Risks Related to Our Company and Our Industry

Our limited operating history may not serve as an adequate measure of our future prospects and results of operations.

There is limited historical information available about our company upon which you can base your evaluation of our business and prospects. We only began
our current solar module manufacturing business in late 2004. As a result, we have shipped only a limited number of solar modules and have recognized limited revenues from sales of our solar modules. Our future success will depend on our ability to
expand our manufacturing capacity significantly beyond its current level. Our business model, technology and ability to achieve satisfactory manufacturing yields for monocrystalline silicon ingots, wafers, cells and modules at higher volumes are
unproven. Accordingly, you should consider our business and prospects in light of the risks, expenses and challenges that we will face as an early-stage company seeking to develop and manufacture new products in a rapidly growing market.

The current industry-wide shortage of polysilicon and the continuing increase of the price of reclaimable silicon may constrain our revenue growth and decrease
our gross margins and profitability.

Polysilicon is an essential raw material in the production of solar cells and modules, and is
also used in the semiconductor industry. There is currently an industry-wide shortage of polysilicon primarily as a result of the growing demand for solar power products. According to Solarbuzz, the average long-term supply contract price of
polysilicon increased from approximately $35-$40 per kilogram delivered in 2005 to $50-$55 per kilogram delivered in 2006, and is expected to increase to $60-$65 per kilogram delivered in 2007. In

addition, according to Solarbuzz, spot prices for incremental supplies of polysilicon, in some cases, reached $300 per kilogram in 2006. We purchase most of
our polysilicon from the spot market using short-term contracts and purchase orders. Based on our experience, we believe that the average price of polysilicon will continue to remain high or increase in the foreseeable future until a significant
portion of polysilicon manufacturing capacity currently under construction becomes available. Any increase in demand from the semiconductor industry will exacerbate the shortage. Increases in the price of polysilicon have in the past increased our
production costs and may adversely impact our cost of revenues and net income.

We purchase polysilicon from a limited number of
international and domestic suppliers. We cannot assure you that our polysilicon procurement strategy will be successful in ensuring an adequate supply of polysilicon at commercially viable prices to meet our solar module production requirements. If
we are unable to meet customer demand for our products because of a shortage of polysilicon, we could lose customers, market share and revenues. This would materially and adversely affect our business, financial condition and results of operations.

To reduce our reliance on polysilicon, we produce monocrystalline silicon ingots and wafers by using a high proportion of reclaimable
silicon raw materials, which include tops and tails of discarded portions of silicon ingots, pot scraps and broken silicon wafers acquired primarily from the semiconductor industry. However, prices of reclaimable silicon raw materials are also
increasing due to growing demand, and we cannot assure you that we will be able to secure sufficient reclaimable silicon raw materials at commercially viable prices. If we fail to procure sufficient reclaimable silicon raw materials at reasonable
prices, we may be unable to timely manufacture our products or our products may be available only at a higher cost, and we could be prevented from delivering our products to our customers in the required quantities and at prices that are profitable.
This would have a materially negative impact on our business, financial condition and results of operations.

We may be adversely affected by
volatile market and industry trends, such as the recent decrease in the price of solar modules.

There are indications that the
solar energy market and industry have been experiencing a price decrease in solar modules since the second half of 2006. Demand for solar modules in major markets, such as Germany, slowed in 2006, partly due to the adverse weather conditions during
the winter season. With the continued strong global growth in production capacity of cells and modules, the production of modules has risen further compared to 2005. For example, companies in the semiconductor industry have begun to move to solar
wafer and cell production. The growth of young but promising markets, such as Spain and Italy, may not be rapid enough to absorb the modules that are made available on the market. As a result, the price of modules has been adversely affected. Our
business may be materially and adversely affected by the negative market and industry trend if it continues, particularly with respect to the fall in the price of solar modules when more existing and new manufacturers are ramping up production
capacity in modules.

We may not be successful in manufacturing solar cells cost-effectively.

We began manufacturing our own solar cells in April 2007. Prior to April 2007, we did not have any significant operating experience in solar cell
manufacturing and face challenges in starting solar cell production. Manufacturing solar cells is a complex process.

##### Table of Contents

Minor deviations in the manufacturing process can cause substantial decreases in yield and cell conversion efficiency and, in some cases, cause production to
be suspended or yield no output. We have made significant capital expenditures to purchase manufacturing equipment for solar cell production. We will also need to invest significantly in research and development in solar cell technology to achieve
the high conversion efficiency rates required for our solar cells and modules to remain competitive. If we face technological difficulties in our production of solar cells, we may be unable to expand our business as planned.

Currently, we have two production lines with an annual manufacturing capacity of 50 MW, and plan to increase our annual manufacturing capacity to 150 MW
by adding four additional lines by the end of 2007. Of the solar cell lines to be added by the end of 2007, we intend to add two lines, equal to approximately 50 MW of capacity, that are capable of producing multicrystalline solar cells. We are
targeting a conversion efficiency of approximately 15.5% for our multicrystalline solar cells. If we fail to implement our plan as expected or experience a delay in the ramp up, our business and results of operations may be materially and adversely
affected.

We may experience difficulty in achieving acceptable yields and product performance as a result of manufacturing problems.

The technology for the manufacture of silicon ingots and wafers is complex, requires costly equipment and is continuously being
modified in an effort to improve yields and product performance. Microscopic impurities such as dust and other contaminants, difficulties in the manufacturing process, disruptions in the supply of utilities or defects in the key materials and tools
used to manufacture wafers can cause a percentage of the wafers to be rejected, which in each case, negatively affects our yields. We have, from time to time, experienced production difficulties that have caused manufacturing delays and lower than
expected yields. Further, most of our equipment is made domestically, which may be less reliable than foreign-made equipment.

Because our
manufacturing capabilities are concentrated in our manufacturing facilities in Changzhou, China, any problem in our facilities may limit our ability to manufacture products. We may encounter problems in our manufacturing facilities, as a result of,
among other things, production failures, construction delays, human errors, equipment malfunction or process contamination, which could seriously harm our operations. We may also experience floods, droughts, power losses and similar events beyond
our control that would affect our facilities. For example, shortages or suspensions of power supplied to us have occasionally occurred due to severe thunderstorms in the area, and have disrupted our operations and caused severe damages to wafers in
the process. A disruption to any step of the manufacturing process will require us to repeat each step and recycle the silicon debris, thus adversely affecting our yields.

The reduction or elimination of government subsidies and economic incentives for on-grid solar energy applications could cause demand for our products and our revenues to decline.

Most of our products are used for on-grid applications, where solar power is used to supplement a customers electricity purchased from the utility
grid. We believe that the near-term growth of the market for on-grid applications depends in large part on the availability and size of government subsidies and economic incentives for the use of solar power. The reduction or elimination of
government subsidies and economic incentives may adversely hinder the growth of this market or result in increased price competition, which could cause our revenues to decline.

Today, the cost of solar power substantially exceeds the cost of power furnished by the electric utility
grid in many locations, when upfront system costs are factored into cost per kilowatt hour. As a result, federal, state and local governmental bodies in many countries, such as Germany, Spain, Italy, the United States, Japan and China, have provided
subsidies and economic incentives in the form of feed-in tariffs, rebates, tax credits and other incentives to distributors, system integrators and manufacturers of solar power products to promote the use of solar energy in on-grid applications and
to reduce dependency on other forms of energy. These government subsidies and economic incentives could be reduced or eliminated altogether. For example, Germany, our most significant market, has been a strong supporter of solar power products and
systems. Utilities in Germany are generally obliged to purchase electricity generated from grid-connected solar power installation at defined feed-in tariff rates, which decline over time according to a predetermined schedule. Any political or
market changes in Germany could result in significant reductions or eliminations of subsidies or economic incentives, such as a more accelerated reduction of feed-in tariffs than as planned according to the current schedule. Reductions in, or
eliminations of, government subsidies and economic incentives for on-grid solar energy applications before the solar power industry reaches the economies of scale necessary for solar power to become cost-effective in a non-subsidized market place
could result in decreased demand for our products and cause our revenues to decline.

Higher interest rates may cause demand for solar power products
to decline.

Some of our end-customers of solar power products rely on long-term loans to finance their purchases of solar power
systems. An increase in interest rates will have the effect of increasing the prices that end-customers pay for solar power products. While we believe that the overall cost of solar power products will decline as the current polysilicon supply
shortage is alleviated, any increase in interest rates may potentially offset some of the benefits derived from reductions in the cost of solar power products, thereby decreasing the demand for our products.

Existing regulations and policies and changes to these regulations and policies may present technical, regulatory and economic barriers to the purchase and use of
solar power products, which may significantly reduce demand for our products.

The market for electricity generation products is
heavily influenced by government regulations and policies concerning the electric utility industry, as well as policies adopted by electric utilities. These regulations and policies often relate to electricity pricing and technical interconnection
of customer-owned electricity generation. In a number of countries, these regulations and policies are being modified and may continue to be modified. Customer purchases of, or further investment in the research and development of, alternative
energy sources, including solar power technology, could be deterred by these regulations and policies, which could result in a significant reduction in the demand for our products. For example, without a regulatory mandated exception for solar power
systems, utility customers are often charged interconnection or standby fees for putting distributed power generation on the electric utility grid. These fees could increase the cost to our customers of using our solar power products and make them
less desirable, thereby harming our business, prospects, results of operations and financial condition.

We anticipate that our products
and their installation will be subject to oversight and

regulation in accordance with national and local regulations relating to building codes, safety, environmental protection, utility interconnection and
metering and related matters. It is difficult to track the requirements of individual jurisdictions and design products to comply with the varying standards. Any new government regulations or utility policies pertaining to our solar power products
may result in significant additional expenses to us and, as a result, could cause a significant reduction in demand for our solar power products.

If
solar power technology is not suitable for widespread adoption, or sufficient demand for solar power products does not develop or takes longer to develop than we anticipate, our revenues may not continue to increase or may even decline, and we may
be unable to sustain our profitability.

The solar power market is at a relatively early stage of development, and the extent of
acceptance of solar power products is uncertain. Market data on the solar power industry are not as readily available as those for other more established industries where trends can be assessed more reliably from data gathered over a longer period
of time. In addition, demand for solar power products in our targeted markets, including Germany, Italy and Spain, may not develop or may develop to a lesser extent than we anticipate. Many factors may affect the viability of widespread adoption of
solar power technology and demand for solar power products, including:

| |  |  | fluctuations in economic and market conditions that affect the viability of conventional and other renewable energy sources, such as increases or decreases in the
prices of oil and other fossil fuels;

If solar power technology is not suitable for widespread adoption or sufficient demand for solar power products does not develop or takes longer to
develop than we anticipate, our revenues may suffer and we may be unable to sustain our profitability.

Further development in multicrystalline
technology or thin-film technologies or other changes in the solar power industry could render our products uncompetitive or obsolete, which could reduce our market share and cause our sales and profit to decline.

The solar power market is characterized by evolving technologies and standards that result in improved features, such as more efficient and higher power
output, improved aesthetics and smaller size. This requires us to develop new solar power products and enhancements for existing solar power products to keep pace with evolving technologies and changing customer requirements.

##### Table of Contents

Currently, we are focused on monocrystalline silicon technology and the expansion of high efficient
production capacity based on monocrystalline silicon. Some of our competitors also produce solar modules using multicrystalline silicon wafers, which have lower energy conversion efficiency. However, producing multicrystalline silicon wafers is
cheaper than producing monocrystalline silicon wafers of similar dimensions.

In addition, thin-film technologies are competing
technologies in the solar power industry. According to Solarbuzz, in 2006, thin-film technologies represented 8% of the solar market, compared to 92% for crystalline technology. Thin-film technologies allow for lower production costs for solar cells
by using lower amounts of semiconductor materials. Thin-film solar cells generally have a lower conversion efficiency rate than crystalline solar cells.

Further development in competing solar power technologies may result in lower manufacturing costs or higher product performance than those expected from our solar modules. We will need to invest significant financial
resources in research and development to maintain our market position, keep pace with technological advances in the solar power industry and effectively compete in the future. Our failure to further refine our technology, enhance our existing solar
power products, or develop and introduce new products, could cause our products to become uncompetitive or obsolete, which could reduce our market share and cause our revenues to decline.

Because the markets in which we compete are highly competitive and many of our competitors have greater resources than us, we may not be able to compete
successfully and we may lose or be unable to gain market share.

The market for solar power products is competitive and fast
evolving. We expect to face increased competition, which may result in price reductions, reduced margins or loss of market share. We compete with other solar module manufacturing companies such as Yingli Green Energy Holding Co., Ltd., BP Solar
International Inc., ErSol Solar Energy AG, Suntech Power Holdings Co., Ltd. and Sunways AG. Some of our competitors also manufacture solar cells and supply us with solar cells. Some of our competitors have also become vertically integrated, from
polysilicon production, silicon ingot and wafer manufacturing to solar power system integration, such as Renewable Energy Corporation ASA and SolarWorld AG. Many of our competitors have a stronger market position than ours, more sophisticated
technologies and products, and larger resources and better name recognition than we have. Further, many of our competitors are developing and are currently producing products based on new solar power technologies, such as thin-film technology, which
may ultimately have costs similar to, or lower than, our projected costs. In addition, the barriers to entry are relatively low in the solar module manufacturing business, given that manufacturing solar modules is labor intensive and requires
limited technology. Because of the current scarcity of polysilicon, supply chain management and financial strengths are the key barriers to entry. However, if the shortage of polysilicon eases, these barriers may no longer exist and many new
competitors may enter the industry and cause the industry to rapidly become over-saturated.

Many of our current and potential competitors
have longer operating histories, greater name recognition, access to larger customer bases and resources and significantly greater economies of scale, financial, sales and marketing, manufacturing, distribution, research and development, technical
and other resources than us. In addition, our competitors may have



10

##### Table of Contents

stronger relationships or may enter into exclusive relationships with some of our key customers. As a result, they may be able to respond more quickly to
changing customer demands or to devote greater resources to the development, promotion and sales of their products than we can. Our business relies on sales of our solar modules, and our competitors with more diversified product offerings may be
better positioned to withstand a decline in the demand for solar modules. New competitors or alliances among existing competitors could emerge and rapidly acquire significant market share, which would harm our business. If we fail to compete
successfully, our business would suffer and we may lose or be unable to gain market share.

Our dependence on a limited number of solar cell
manufacturers could prevent us from timely delivering our products to our customers in the required quantities, which could result in order cancellations and decreased revenues.

We currently enter into toll manufacturing arrangements by providing silicon wafers to toll manufacturers and receiving solar cells from them in return.
In connection with such toll manufacturing arrangements, we rely on third-party toll manufacturers technologies to convert silicon wafers into solar cells. Our major suppliers of solar cells include Suntech Power Holdings Co., Ltd., Q-Cells
AG, Motech Industries Inc. and DelSolar Co., Ltd. Some of our suppliers are also competitors as they are also makers of solar modules. To reduce our reliance on the toll manufacturers, we built our own solar cell lines with an initial annual
manufacturing capacity of 50 MW to produce solar cells for use in our solar modules. However, if we fail to develop or maintain our relationships with these or our other manufacturers or if these manufacturers experience delays in supplying solar
cells to us, we may be unable to timely manufacture our products or our products may be available only at a higher cost, and we could be prevented from delivering our products to our customers in the required quantities and at prices that are
profitable. These manufacturers could also decide not to supply solar cells to us due to competitive concerns. Problems of this kind could cause us to experience order cancellations and loss of market share and harm our reputation.

Noncompliance with present or future construction and environmental regulations may result in potentially significant monetary damages and fines.

In the past, we had begun constructing and operating facilities without having obtained all of the necessary construction and
environmental permits. Although we have subsequently obtained all of the construction and environmental permits for these facilities, we could be subject to fines or penalties for our past non-compliance.

Because our manufacturing processes generate noise, waste water, gaseous wastes and other industrial wastes, we are required to comply with national and
local environmental regulations. If we fail to comply with present or future environmental regulations, we may be required to pay substantial fines, suspend production or cease operations. Any failure by us to control the use or to restrict
adequately the discharge of hazardous substances could subject us to potentially significant monetary damages and fines or suspensions in our business operations, which would have a materially adverse effect on our business and results of
operations.

Our costs and expenses may increase as a result of entering into fixed price, prepaid arrangements with our suppliers.

We plan to secure our supply of polysilicon increasingly through fixed-price, prepaid



11



---

##### Table of Contents

supply arrangements with both overseas and domestic suppliers. If the price of polysilicon decreases in the future and we are locked into fixed price,
prepaid arrangements, our cost of revenues will be higher than otherwise. Additionally, if demand for our solar modules decreases, we may incur costs associated with carrying excess inventory, which may have a material adverse effect on our cash
flows. To the extent we are not able to pass these increased costs and expenses on to our customers, our business, results of operations and financial condition may be materially and adversely affected. Since some of our supply contracts may require
pre-payment of a substantial portion of the contract price, we may not be able to recover such pre-payments and would suffer losses should such suppliers fail to fulfill their delivery obligations under the contracts or fail to deliver raw materials
meeting the quality stipulated in the contracts. For example, in 2006, we incurred a charge of $2.2 million resulting from failures of three of our suppliers to deliver goods as specified in the contracts and to reimburse us for our advance payment
due to such suppliers own financial difficulties. Such incidents could occur in the future and could have a material adverse effect on our operations.

Our future success substantially depends on our ability to significantly expand both our manufacturing capacity and output, which exposes us to a number of risks and uncertainties.

Our future success depends on our ability to significantly increase both our manufacturing capacity and output. If we are unable to do so, we may be
unable to expand our business, decrease our costs per watt, maintain our competitive position and improve our profitability. Our ability to establish additional manufacturing capacity and increase output is subject to significant risks and
uncertainties, including:



| |  |  | the need to raise significant additional funds to purchase raw materials or to build additional manufacturing facilities, which we may be unable to obtain on
commercially viable terms or at all;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays and cost overruns as a result of a number of factors, many of which are beyond our control, such as increases in the price of polysilicon and problems with
equipment vendors, particularly with respect to major equipment such as monocrystalline ingot pulling machines;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays or denial of required approvals by relevant government authorities;
| | - |  | --------------------------------------------------------------------------



| |  |  | diversion of significant management attention and other resources; and
| | - |  | ----------------------------------------------------------------------



| |  |  | failure to execute our expansion plan effectively.
| | - |  | --------------------------------------------------

If we are unable to establish or successfully operate additional manufacturing capacity, or if we encounter any of the risks described above, we may be unable to expand our business as planned. Moreover, even if we do
expand our manufacturing capacity we might not be able to generate sufficient customer demand for our solar power products to support our increased production levels.

In particular, we believe that the expansion of our manufacturing capacity is an integral part of our long-term strategy to achieve a grid parity cost structure. Our ability to meet our estimate for the scale of
production needed to achieve grid parity is affected by a number of factors, including our ability to achieve vertical integration and to increase our



12



---

##### Table of Contents

efficiencies and margins, the likelihood that we may approach or reach a point of diminishing returns as we continue to expand our scale, the average
purchase price of silicon we will pay in the future to meet our expansion requirements, and the cost of conventional grid electricity which will determine at which point grid parity can be reached. We might not be able to meet our desired scale of
production in order to fully implement our strategy.

Our dependence on a limited number of customers may cause significant fluctuations or declines
in our revenues.

We currently sell a substantial portion of our solar modules to a limited number of customers. In 2005 and 2006,
sales to our top five customers accounted for approximately 59.1% and 48.9%, respectively, of our total net revenues. Each of Inowatt Elektro Technik GmbH and Soleko GmbH contributed over 10% of our net revenues in 2005. Each of Corporación
Zigor S.A. and Scatec AS contributed over 10% of our net revenues in 2006.

Sales to our customers are typically made through
non-exclusive, short-term arrangements. We anticipate that our dependence on a limited number of customers will continue for the foreseeable future. Consequently, any one of the following events may cause material fluctuations or declines in our
revenues:



| |  |  | reduction, delay or cancellation of orders from one or more of our significant customers;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | selection by one or more of our significant customers of products competitive with ours;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | loss of one or more of our significant customers due to disputes, dissatisfaction with our products or otherwise, and our failure to attract additional or
replacement customers; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | failure of any of our significant customers to make timely payment for our products.
| | - |  | ------------------------------------------------------------------------------------

Our business depends substantially on the continuing efforts of our executive officers, and our business may be severely disrupted if we lose their services.

Our future success depends substantially on the continued services of our executive officers, especially Mr. Jifan Gao, our
chairman and chief executive officer. If one or more of our executive officers or key employees were unable or unwilling to continue in their present positions, we might not be able to replace them easily or at all. Our business may be severely
disrupted, our financial condition and results of operations may be materially and adversely affected, and we may incur additional expenses to recruit, train and retain personnel. Since our industry is characterized by high demand and intense
competition for talent, we also may not be able to attract or retain additional highly skilled employees or other key personnel that we will need to achieve our strategic objectives. As we are still a relatively young company and our business has
grown rapidly, our ability to train and integrate new employees into our operations may not meet the growing demands of our business.

If
any of our executive officers or key employees joins a competitor or forms a competing company, we may lose customers, suppliers, know-how and key professionals and staff members. Each of our executive officers has entered into an employment
agreement



13

##### Table of Contents

with us, which contains non-competition provisions. However, if any dispute arises between our executive officers and us, these agreements may not be
enforceable in China, where these executive officers reside, in light of the uncertainties with Chinas legal system. See Risks Related to Doing Business in ChinaUncertainties with respect to the Chinese legal system could
have a material adverse effect on us.

If we fail to manage our growth effectively, our business may be adversely affected.

We have experienced a period of rapid growth and expansion that has placed, and continues to place, significant strain on our management personnel,
systems and resources. To accommodate our growth, we anticipate that we will need to implement a variety of new and upgraded operational and financial systems, procedures and controls, including the improvement of our accounting and other internal
management systems, all of which require substantial management efforts. We also will need to continue to expand, train, manage and motivate our workforce, manage our customer relationships and manage our relationship with foundries and assembly and
testing houses. All of these endeavors will require substantial management effort and skill and incurrence of additional expenditures. We might not be able to manage our growth effectively, and any failure to do so may have a material adverse effect
on our business.

Future acquisitions may have an adverse effect on our ability to manage our business.

If we are presented with appropriate opportunities, we may acquire technologies, businesses or assets that are complementary to our business. Future
acquisitions would expose us to potential risks, including risks associated with the assimilation of new technologies, businesses and personnel, unforeseen or hidden liabilities, the diversion of management attention and resources from our existing
business, and the inability to generate sufficient revenues to offset the costs and expenses of acquisitions. Any difficulties encountered in the acquisition and integration process may have an adverse effect on our ability to manage our business.

We face risks associated with the marketing, distribution and sale of our solar power products internationally, and if we are unable to effectively
manage these risks, they could impair our ability to expand our business abroad.

In 2005 and 2006, we sold approximately 96.9% and
90.7%, respectively, of our products to customers outside of China. The marketing, distribution and sale of our solar power products in the international markets expose us to a number of risks, including:



| |  |  | fluctuations in currency exchange rates;
| | - |  | ----------------------------------------



| |  |  | difficulty in engaging and retaining distributors who are knowledgeable about, and can function effectively in, overseas markets;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | increased costs associated with maintaining marketing efforts in various countries;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | difficulty and costs relating to compliance with the different commercial and legal requirements of the overseas markets in which we offer our products; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | trade barriers such as export requirements, tariffs, taxes and other restrictions and expenses, which could increase the prices of our products and make us less
competitive in some countries.

Problems with product quality or product performance may cause us to incur significant warranty expenses, which may
damage our market reputation, reduce our market share and cause sales to decline.

Our products may contain defects that are not
detected until after they are shipped or are installed because we cannot test for all possible scenarios. In addition, as we currently use toll manufacturers to produce solar cells for our modules, we have limited control over the quality of the
solar cells we receive. Unlike solar modules, which are subject to certain uniform international standards, solar cells generally are not subject to uniform international standards, and it is often difficult to determine whether solar power product
defects are a result of defective solar cells or other defective components of solar modules or other reasons. Furthermore, the solar cells and other components that we purchase from third-party suppliers are typically sold to us with no or only
limited warranties.

On the other hand, our solar modules are typically sold with a two-year warranty for defects in material and
workmanship and a minimum power output warranty of up to 25 years following the date of purchase or installation. We believe our warranty periods are consistent with industry practice. We have only begun to sell solar modules since November 2004.
Although we conduct accelerated reliability testing of our solar modules, our solar modules have not been and cannot be tested in an environment simulating the 2-year and 25-year warranty periods. As a result, we may be subject to unexpected
warranty expense and associated harm to our financial results for as long as 25 years after the sale of our products. Any increase in the defect rate of our products would cause us to increase the amount of our warranty reserves and have a
correspondingly negative impact on our operating results. Furthermore, widespread product failures may damage our market reputation, reduce our market share and cause our sales to decline.

If we are unable to attract, train and retain qualified technical personnel, our business may be materially and adversely affected.

Our future success depends, to a significant extent, on our ability to attract, train and retain qualified technical personnel, particularly those with
expertise in the solar power industry. There is substantial competition for qualified technical personnel, and we might not be able to attract or retain our qualified technical personnel. If we are unable to do so, our business may be materially and
adversely affected.

We may be exposed to infringement or misappropriation claims by third parties, which, if determined adversely to us, could cause
us to pay significant damage awards.

Our success depends largely on our ability to use and develop our technology and know-how
without infringing the intellectual property rights of third parties. The validity and scope of claims relating to solar power technology patents involve complex scientific, legal and factual questions and analysis and, therefore, may be highly
uncertain. We may be subject to litigation involving claims of patent infringement or violation of intellectual property rights of third parties. The defense and prosecution of intellectual property suits, patent opposition proceedings and related
legal and administrative proceedings can be both costly and time consuming and may significantly divert the efforts and resources of our technical and management personnel. An adverse determination in any such litigation or proceedings to which we
may become a party could subject us to significant liability to third



15

##### Table of Contents

parties, require us to seek licenses from third parties, to pay ongoing royalties, or to redesign our products or subject us to injunctions prohibiting the
manufacture and sale of our products or the use of our technologies. Protracted litigation could also result in our customers or potential customers deferring or limiting their purchase or use of our products until resolution of such litigation.

We have limited insurance coverage and may incur losses resulting from product liability claims.

As with other solar power product manufacturers, we are exposed to risks associated with product liability claims if the use of our solar power products
results in injury. Since our products generate electricity, it is possible that users could be injured or killed by our products as a result of product malfunctions, defects, improper installation or other causes. We only began commercial shipment
of our solar modules in November 2004 and, because of our limited operating history, we cannot predict whether product liability claims will be brought against us in the future or the effect of any resulting negative publicity on our business.
Moreover, we do not have any product liability insurance and may not have adequate resources to satisfy a judgment in the event of a successful claim against us. The successful assertion of product liability claims against us could result in
potentially significant monetary damages and require us to make significant payments.

We have significant outstanding bank borrowings, and we may
not be able to arrange adequate financing when they mature.

As of December 31, 2006, we had $93.4 million in cash and cash
equivalents and $76.5 million in outstanding borrowings, of which approximately $71.4 million was due within one year. We might not be able to obtain extensions of these borrowings in the future as they mature. In the event we are unable to obtain
extensions of these borrowings, or if we are unable to obtain sufficient alternative funding at reasonable terms to make repayments, we will have to repay these borrowings with cash generated by our operating activities. Our business might not
generate sufficient cash flow from operations to repay these borrowings, some of which are secured by significant amounts of our assets. In addition, repaying these borrowings with cash generated by our operating activities will divert our financial
resources from the requirements of our ongoing operations and future growth, and would have a material adverse effect on our business, financial condition and future prospects.

There were historical deficiencies with our internal controls and there remain areas of our internal and disclosure controls that require improvement. If we fail to maintain an effective system of internal
controls, we may be unable to accurately report our financial results or prevent fraud, and investor confidence and the market price of our common shares may, therefore, be adversely impacted.

We are subject to reporting obligations under the U.S. securities laws. The Securities and Exchange Commission, or the SEC, as required by
Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, adopted rules requiring every public company to include a management report on such companys internal controls over financial reporting in its annual report, which
contains managements assessment of the effectiveness of its internal controls over financial reporting. In addition, an independent registered public accounting firm must attest to and report on managements assessment of the
effectiveness of the companys internal controls over financial reporting. These requirements will first apply to us for the fiscal year ending on December 31, 2007. Our management may conclude that our



16



---

##### Table of Contents

internal controls over our financial reporting are not effective. Moreover, even if our management concludes that our internal controls over financial
reporting is effective, our independent registered public accounting firm may still decline to attest to our managements assessment or may issue a report that is qualified if it is not satisfied with our internal controls or the level at which
our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. Our reporting obligations as a public company place a significant strain on our management, operational and financial
resources and systems.

Prior to our initial public offering, we were a young, private company with limited accounting and other resources
with which to adequately address our internal controls and procedures. As a result, in our past audits, our auditors had identified material weaknesses and deficiencies with our internal controls. In our audit for the fiscal year ended
December 31, 2006, our auditors observed a number of weaknesses and deficiencies with respect to our internal controls under the standards established by the Public Company Accounting Oversight Board. The material weaknesses identified by our
independent registered public accounting firm include (i) insufficient accounting resources to properly identify adjustments, analyze transactions and prepare financial statements in accordance with U.S. GAAP, (ii) a lack of formal
accounting policies and procedures for U.S. GAAP to ensure that our accounting policies and procedures are appropriately or consistently applied, and (iii) weaknesses in our inventory management. Following the identification of these material
weaknesses and other deficiencies, we have undertaken remedial steps to address them, including hiring additional staff, training our new and existing staff and augmenting our financial information technology systems.

We plan to continue to take additional steps to improve our internal and disclosure controls to meet the deadline for compliance with the requirements of
Section 404 of the Sarbanes-Oxley Act. If, however, we fail to maintain the adequacy of our internal controls, we may not be able to conclude that we have effective internal controls over financial reporting. Moreover, effective internal
controls over financial reporting are necessary for us to produce reliable financial reports and are important to help prevent fraud. As a result, our failure to achieve and maintain effective internal controls over financial reporting could result
in the loss of investor confidence in the reliability of our financial statements, which in turn could harm our business and negatively impact the trading price of our ADSs. Furthermore, we anticipate that we will incur considerable costs and devote
significant management time and efforts and other resources to comply with Section 404 of the Sarbanes-Oxley Act.

Trina or Trina China may be
required by the PRC tax authorities to withhold capital gains tax arising out of our restructuring in May 2006.

In connection with
our restructuring in May 2006, certain former shareholders of Trina China transferred their equity interests in Trina China to Trina for a nominal consideration. As a result of the nominal consideration paid in these related party transactions, such
consideration may be subject to pricing reassessment by the PRC tax authorities, leading to a recognition of capital gains by the transferring shareholders which would be subject to PRC tax. PRC tax law provides a safe harbor exemption from such
capital gains tax in the case of an intra-group restructuring. While our restructuring does not fall squarely within the requirements for the safe harbor, we believe that the PRC tax authorities may deem the restructuring to meet substantially all
of the requirements for the safe harbor for tax-free treatment. The PRC tax authorities could, however, deem these transferring shareholders to have realized capital gains as a result of the restructuring.



17



---

##### Table of Contents

Under PRC tax law, if a transferor is a foreign person without a presence in China, the transferee is
obligated to withhold tax on any of the transferors gains arising from the transaction. As all of these transferring shareholders are deemed to be foreign persons without a presence in China, Trina China may be required to withhold tax on
capital gains deemed to have been received by these former shareholders. These former shareholders have agreed to indemnify us against any withholding obligations or liabilities due to or imposed by the PRC tax authorities that may arise out of the
restructuring. The PRC tax authorities could impose such withholding obligation on Trina or Trina China or impose fines or penalties on Trina or Trina China for its failure to make such withholding. If such withholding obligation is imposed and we
are not indemnified by these transferring shareholders, our potential tax exposure would be approximately $2.8 million, excluding any fines or penalties. The amount of such fines or penalties is difficult to estimate as the determination of whether
any such fines or penalties would be imposed and the amount of such fines or penalties are at the discretion of the PRC tax authorities.

Our
principal shareholders have substantial influence over our company and their interests may not be aligned with the interests of our other shareholders.

Our principal shareholders have substantial influence over our business, including decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, election of directors and other
significant corporate actions. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our
company and might reduce the price of our ADSs. These actions may be taken even if they are opposed by our other shareholders. Furthermore, our articles of association contain a quorum requirement of at least one-third of our total outstanding
shares present in person or by proxy. Two or more shareholders with an aggregate shareholding of more than one-third could constitute a quorum and approve actions which may not be in the best interest of our other shareholders.

Fluctuations in exchange rates could adversely affect our business.

Most of our sales are denominated in U.S. dollars, with the remainder in Renminbi and Euros, while a substantial portion of our costs and expenses is denominated in U.S. dollars, with the remainder in Renminbi.
Fluctuations in exchange rates, particularly among the U.S. dollar, Renminbi and Euro, may affect our net profit margins and could result in fluctuations in foreign exchange and operating gains and losses. In 2006, we entered into two short-term
foreign exchange derivative contracts to protect against volatility of cash flows caused by fluctuations in exchange rates between Renminbi and U.S. dollars. As of December 31, 2006, we had no outstanding foreign exchange hedge contracts. We
have not used any other forward contracts, currency options or borrowings to hedge our exposure to foreign currency exchange risk. We cannot predict the impact of future exchange rate fluctuations on our results of operations and may incur net
foreign currency losses in the future.

Risks Related to Doing Business in China

Adverse changes in political and economic policies of the PRC government could have a material adverse effect on the overall economic growth of China, which could reduce the demand for our products and
materially and adversely affect our competitive position.

All of our business operations are conducted in China and some of our
sales are made in China. Accordingly, our business, financial condition, results of operations and prospects are affected significantly by economic, political and legal developments in China. The Chinese economy differs from the economies of most
developed countries in many respects, including:



| |  |  | the amount of government involvement;
| | - |  | -------------------------------------



| |  |  | the level of development;
| | - |  | -------------------------



| |  |  | the growth rate;
| | - |  | ----------------



| |  |  | the control of foreign exchange; and
| | - |  | ------------------------------------



| |  |  | the allocation of resources.
| | - |  | ----------------------------

While
the Chinese economy has grown significantly in the past 20 years, the growth has been uneven, both geographically and among various sectors of the economy. The PRC government has implemented various measures to encourage economic growth and guide
the allocation of resources. Some of these measures benefit the overall Chinese economy, but may also have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over
capital investments or changes in tax regulations that are applicable to us.

The Chinese economy has been transitioning from a planned
economy to a more market-oriented economy. Although in recent years the PRC government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets and the
establishment of sound corporate governance in business enterprises, a substantial portion of the productive assets in China is still owned by the PRC government. The continued control of these assets and other aspects of the national economy by the
PRC government could materially and adversely affect our business. The PRC government also exercises significant control over Chinese economic growth through the allocation of resources, controlling payment of foreign currency-denominated
obligations, setting monetary policy and providing preferential treatment to particular industries or companies. Efforts by the PRC government to slow the pace of growth of the Chinese economy could result in decreased capital expenditure by solar
energy users, which in turn could reduce demand for our products.

Uncertainties with respect to the Chinese legal system could have a material
adverse effect on us.

We conduct substantially all of our manufacturing operations through our wholly-owned subsidiary, Trina
China, a limited liability company established in China. Trina China is generally subject to laws and regulations applicable to foreign investment in China and, in particular, laws applicable to wholly foreign-owned enterprises. The PRC legal system
is based on written statutes. Prior court decisions may be cited for reference but have limited precedential value. Since 1979, PRC legislation and regulations have significantly enhanced the protections afforded to various forms of foreign
investments in China. However, since these laws and regulations are relatively new and the PRC legal system continues to rapidly evolve, the interpretations of many laws, regulations and rules are not always uniform and enforcement of these laws,
regulations and rules involves uncertainties. We cannot predict the



19



---

##### Table of Contents

effect of future developments in the PRC legal system, including the promulgation of new laws, changes to existing laws or the interpretation or enforcement
thereof, the preemption of local regulations by national laws, or the overturn of local governments decisions by the superior government. These uncertainties may limit legal protections available to us. In addition, any litigation in China may
be protracted and result in substantial costs and diversion of resources and management attention.

We rely on dividends paid by our subsidiary for
our cash needs.

We conduct substantially all of our operations through Trina China. We rely on dividends paid by Trina China for
our cash needs, including the funds necessary to pay dividends and other cash distributions to our shareholders, to service any debt we may incur and to pay our operating expenses. The payment of dividends by entities organized in China is subject
to limitations. Regulations in the PRC currently permit payment of dividends only out of accumulated profits as determined in accordance with accounting standards and regulations in China. According to the relevant PRC laws and regulations
applicable to Trina China and its articles of association, Trina China is required to maintain a general reserve fund and a staff welfare and bonus fund. Contributions to such reserves are made from Trina Chinas net profit after taxation. As a
result of these PRC laws and regulations, Trina China is restricted in its ability to transfer the net profit to us in the form of dividends. In addition, under a new PRC tax law to be effective in January 2008, dividends from Trina China to us may
become subject to a 20% withholding tax. See Item 3. Key InformationD. Risk FactorsRisks Related to Doing Business in ChinaOur business benefits from certain PRC government tax incentives, and the expiration of, or changes
to, these incentives could have a material adverse effect on our results of operations and Item 4. Information on the CompanyRegulationTax. Furthermore, if Trina China incurs debt on its own behalf in the future, the
instruments governing the debt may restrict its ability to pay dividends or make other distributions to us.

Fluctuation in the value of the Renminbi
may have a material adverse effect on your investment.

The change in value of the Renminbi against the U.S. dollar, Euro and other
currencies is affected by, among other things, changes in Chinas political and economic conditions. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar. Under the new
policy, the Renminbi is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change in policy has resulted in an approximately 8.0% appreciation of Renminbi against the U.S. dollar between
July 21, 2005 and June 8, 2007. While the international reaction to the Renminbi revaluation has generally been positive, there remains significant international pressure on the PRC government to adopt an even more flexible currency
policy, which could result in a further and more significant appreciation of the Renminbi against the U.S. dollar. On May 18, 2007, Chinas central bank announced that it would allow Renminbi to fluctuate more during each days
foreign exchange rate trading. As a portion of our costs and expenses is denominated in Renminbi, the revaluation in July 2005 and potential future adjustment or revaluation have increased and could further increase our costs in U.S. dollar terms.
In addition, as we rely entirely on dividends paid to us by Trina China, any significant adjustment or revaluation of the Renminbi may have a material adverse effect on our revenues and financial condition, and the value of, and any dividends
payable on, our ordinary shares or ADSs. For example, to the extent that we need to convert U.S. dollars we receive from our overseas sales into Renminbi for our operations, appreciation of the

Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we receive from the conversion. Conversely, if we decide to convert our
Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount
available to us.

Restrictions on currency exchange may limit our ability to receive and use our revenues effectively.

Certain portions of our revenues and expenses are denominated in Renminbi. If our revenues denominated in Renminbi increase or expenses denominated in
Renminbi decrease in the future, we may need to convert a portion of our revenues into other currencies to meet our foreign currency obligations, including, among others, payment of dividends declared, if any, in respect of our ordinary shares or
ADSs. Under Chinas existing foreign exchange regulations, Trina China is able to pay dividends in foreign currencies without prior approval from the State Administration of Foreign Exchange, or SAFE, by complying with certain procedural
requirements. However, the PRC government could take further measures in the future to restrict access to foreign currencies for current account transactions.

Foreign exchange transactions by Trina China under capital accounts continue to be subject to significant foreign exchange controls and require the approval of, or registration with, PRC governmental authorities. In
particular, if Trina China borrows foreign currency loans from us or other foreign lenders, these loans must be registered with the SAFE, and if we finance Trina China by means of additional capital contributions, these capital contributions must be
approved by certain government authorities including the Ministry of Commerce or its local counterparts. These limitations could affect the ability of Trina China to obtain foreign exchange through debt or equity financing.

Our business benefits from certain PRC government tax incentives, and expiration of, or changes to, these incentives could have a material adverse effect on our
results of operations

The PRC government has provided various incentives to foreign invested enterprises. Because Trina China is a
foreign invested enterprise engaged in manufacturing businesses and located in Changzhou, which is within a coastal economic zone, it is entitled to a preferential enterprise income tax rate of 24%. In addition, Trina China has been qualified as an
advanced technological enterprise and, as a result, enjoyed a preferential enterprise income tax rate of 12% for the years 2004 to 2006. As the tax benefit for an advanced technological enterprise expired in 2006, the tax
rate of Trina China has increased to 27% (24% enterprise income tax plus 3% local income tax) in 2007. However, because income from incremental investment to the registered capital of a foreign invested enterprise is entitled to a two-year exemption
and a 50% reduction of the applicable income tax rate for the succeeding three years, and Trina Chinas registered capital was increased from $7.28 million to $40 million, Trina China is eligible for an income tax exemption for 81.8% of its
income from August 2006 to December 2007 and a 50% reduction from January 2008 to December 2010. 18.2% of Trina Chinas income remains subject to a tax rate of 27% starting from January 2007. In addition, Chinas parliament, the National
Peoples Congress, adopted the Enterprise Income Tax Law on March 16, 2007. This new tax law will replace the existing separate income tax laws for domestic enterprises and foreign-invested enterprises and become effective on
January 1, 2008. Under the new tax law, a unified enterprise income tax rate is set at 25% for both domestic enterprises and foreign-invested enterprises.

However, there will be a five-year transition period for foreign-invested enterprises. In addition, an enterprise that enjoys a preferential tax treatment
for a fixed term may continue to enjoy such treatment until the fixed term expires. During the transition period, Trina China will be allowed to continue to enjoy the existing preferential tax treatment. In addition, under the new tax law, a
resident enterprise, which includes an enterprise established outside of China with management located in China, will be subject to PRC income tax. If the PRC tax authorities subsequently determine that Trina should be deemed a resident
enterprise, then Trinas global income will be subject to PRC income tax at a tax rate of 25%. The exemption to the 20% withholding tax on dividends distributed by foreign-invested enterprises to their foreign investors under the current tax
laws may no longer be available under the new tax law. Since the new law has only been adopted recently, there is uncertainly as to how it should be interpreted or implemented. Any discontinuation of tax preferential tax treatment, any increase of
the enterprise income tax rate applicable to Trina China, the imposition of PRC income tax on Trinas global income or the imposition of withholding tax on dividends distributed from Trina China to Trina could have a material adverse effect on
our financial condition and results of operations.

The approval of the Chinese Securities Regulatory Commission might have been required in
connection with our initial public offering under a recently adopted PRC regulation, and, if required, we could be subject to sanction, fines and other penalties.

On August 8, 2006, six PRC regulatory agencies, including the Chinese Securities Regulatory Commission, or CSRC, promulgated the Regulation on Mergers and Acquisitions of Domestic Companies by Foreign Investors,
which became effective on September 8, 2006. This new regulation, among other things, requires offshore special purpose vehicles, formed for overseas listing purposes through acquisitions of PRC domestic companies and controlled by PRC
individuals, to obtain the approval of the CSRC prior to publicly listing their securities on an overseas stock exchange. We believe, based on the advice of Fangda Partners, our PRC counsel, that this regulation does not apply to us and that CSRC
approval is not required because (1) Trina is not a special purpose vehicle formed for the purpose of acquiring a PRC domestic company because Trina China was a foreign-invested enterprise before it was acquired by Trina, and, accordingly,
Trina China did not fall within the definition of a PRC domestic company as set forth in the new regulation; and (2) such acquisition was completed before the new regulation became effective. On September 21, 2006, the CSRC published a
notice specifying the documents and materials that are required to be submitted for obtaining CSRC approval. In the opinion of Fangda Partners, the new notice does not contradict its interpretation of the new regulation, nor does it add greater
clarity to the applicability of the new regulation to us or our initial public offering. Based on the advice we have received from our PRC counsel, we did not seek the CSRC approval in connection with our initial public offering.

Since the new regulation has only recently been adopted, there is some uncertainty as to how this regulation will be interpreted or implemented. If the
CSRC or other PRC regulatory body subsequently determines that the CSRCs approval was required for our initial public offering, we may face sanctions by the CSRC or other PRC regulatory agencies. In that case, these regulatory agencies may
impose fines and penalties on our operations in the PRC, limit our operating privileges in the PRC, restrict or prohibit payment or remittance of dividends by Trina China, or take other actions that could have a material adverse effect on our
business, financial condition, results of operations, reputation and prospects, as well as the trading price of our ADSs.

Recent regulations relating to offshore investment activities by PRC residents may limit our ability to acquire PRC
companies and could adversely affect our business, financial condition and results of operations.

In October 2005, SAFE
promulgated a regulation known as Circular No. 75. that states that if PRC residents use assets or equity interests in their PRC entities as capital contributions to establish offshore companies or inject assets or equity interests of their PRC
entities into offshore companies to raise capital overseas, they must register with local SAFE branches with respect to their overseas investments in offshore companies. They must also file amendments to their registrations if their offshore
companies experience material events involving capital variation, such as changes in share capital, share transfers, mergers and acquisitions, spin-off transactions, long-term equity or debt investments or uses of assets in China to guarantee
offshore obligations. Under this regulation, failure to comply with the registration procedures set forth in such regulation may result in restrictions being imposed on the foreign exchange activities of the relevant PRC entity, including the
payment of dividends and other distributions to its offshore parent, as well as restrictions on the capital inflow from the offshore entity to the PRC entity. While we believe our shareholders have complied with existing SAFE registration
procedures, any future failure by any of our shareholders who is a PRC resident, or controlled by a PRC resident, to comply with relevant requirements under this regulation could subject our company to fines or sanctions imposed by the PRC
government, including restrictions on Trina Chinas ability to pay dividends or make distributions to us and our ability to increase our investment in or to provide loans to Trina China.

We face risks related to health epidemics and other outbreaks.

Our business could be adversely affected by the effects of avian flu, SARS or other epidemics or outbreaks. China reported a number of cases of SARS in April 2004. In 2005 and 2006, there have been reports on the
occurrences of avian flu in various parts of China, including a few confirmed human cases and deaths. Any prolonged recurrence of avian flu, SARS or other adverse public health developments in China may have a material adverse effect on our business
operations. These could include our ability to travel or ship our products outside of China, as well as temporary closure of our manufacturing facilities. Such closures or travel or shipment restrictions would severely disrupt our business
operations and adversely affect our results of operations. We have not adopted any written preventive measures or contingency plans to combat any future outbreak of avian flu, SARS or any other epidemic.

Risks Related to Our Ordinary Shares and ADSs

| | - |  | --------------------------------------------

In addition, the securities markets have from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies. These market fluctuations may also have a material
adverse effect on the market price of our ADSs.

Substantial future sales or perceived sales of our ADSs or ordinary shares in the public market
could cause the price of our ADSs to decline.

Sales of our ADSs or ordinary shares in the public market, or the perception that
these sales could occur, could cause the market price of our ADSs to decline. As of date of this annual report, we had 2,537,687,322 ordinary shares outstanding, including 1,121,658,000 ordinary shares represented by 11,216,580 ADSs. All ADSs are
freely transferable without restriction or additional registration under the Securities Act of 1933. All shares owned by our directors, executive officers, selling shareholders and certain other shareholders will be available for sale upon the
expiration of the 90-day lock-up period from May 31, 2007 placed on those shares in connection with our follow-on public offering, subject to volume and other restrictions as applicable under Rule 144 and Rule 701 under the Securities Act. Any
or all of these shares may be released prior to expiration of the relevant lock-up period at the discretion of the underwriters. For example, the underwriters have waived the lock-up provisions with respect to the shares being sold by us and the
selling shareholders in our follow-on public offering that were placed on those shares in connection with our initial public offering. To the extent shares are released before the expiration of the relevant lock-up period and these shares are sold
into the market, the market price of our ADSs could decline.

Holders of our ADSs do not have the same voting rights as the holders of our ordinary
shares and may not receive voting materials in time to be able to exercise their right to vote.

Holders of our ADSs are not
treated as one of our shareholders. Instead, the depositary will be treated as the holder of the shares underlying ADSs. Holders of our ADSs, however, may exercise some of the shareholders rights through the depositary and have the right to
withdraw the shares underlying their ADSs from the deposit facility.

Except as described in this annual report and provided in the deposit agreement, holders of our ADSs will
not be able to exercise voting rights attaching to the shares evidenced by our ADSs on an individual basis. Holders of our ADSs may instruct the depositary to exercise the voting rights attaching to the shares represented by the ADSs. If no
instructions are received by the depositary on or before a date established by the depositary, the depositary shall deem the holders to have instructed it to give a discretionary proxy to a person designated by us to exercise their voting rights.
Holders of our ADSs may not receive voting materials in time to instruct the depositary to vote, and holders of our ADSs, or persons who hold their ADSs through brokers, dealers or other third parties, might not have the opportunity to exercise a
right to vote.

Holders of our ADSs may not be able to participate in rights offerings that are made available to our shareholders, and may not
receive cash dividends if it is impractical to make them available to them.

We may from time to time distribute rights to our
shareholders, including rights to acquire our securities. Under the deposit agreement, the depositary bank will not make rights available to holders of our ADSs unless the distribution to ADS holders of both the rights and any related securities are
either registered under the Securities Act, or exempted from registration under the Securities Act with respect to all holders of ADSs. We are under no obligation to file a registration statement with respect to any such rights or securities or to
endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. Accordingly, holders of our ADSs, may be unable to participate in our rights
offerings and may experience dilution in their holdings.

In addition, the depositary of our ADSs has agreed to pay to holders of our ADSs
the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. Holders of our ADSs will receive these distributions in proportion to the number of
ordinary shares their ADSs represent. However, the depositary may, at its discretion, decide that it is inequitable or impractical to make a distribution available to any holders of ADSs. For example, the depositary may determine that it is not
practicable to distribute certain property through the mail, or that the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may decide not to distribute such property and holders of our ADSs will
not receive such distribution.

Holders of our ADSs may be subject to limitations on transfer of their ADSs.

Our ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it
deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or
the depositary deem it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

We are a Cayman Islands company and, because judicial precedent regarding the rights of shareholders is more
limited under Cayman Islands law than that under U.S. law, our shareholders may have less protection for their shareholder rights than they would under U.S. law.

Our corporate affairs are governed by our memorandum and articles of association, the Cayman Islands Companies Law and the common law of the Cayman Islands. The rights of shareholders to take action against the
directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in
part from comparatively limited judicial precedent in the Cayman Islands as well as that from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands. The rights of our shareholders and the fiduciary
responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body
of securities laws than the United States. In addition, some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. As a result of all of the above, shareholders of a
Cayman Islands company may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as shareholders of a company incorporated in a
jurisdiction in the United States. The limitations described above will also apply to the depositary, which is treated as the holder of the shares underlying our ADSs.

You may have difficulty enforcing judgments obtained against us.

We are a Cayman Islands
company and substantially all of our assets are located outside of the United States. Substantially all of our current operations are conducted in the PRC. In addition, most of our directors and officers are nationals and residents of countries
other than the United States. A substantial portion of the assets of these persons are located outside the United States. As a result, it may be difficult for you to effect service of process within the United States upon these persons. It may also
be difficult for you to enforce in U.S. courts judgments obtained in U.S. courts based on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors, most of whom are not residents in the United
States and the substantial majority of whose assets are located outside of the United States. In addition, there is uncertainty as to whether the courts of the Cayman Islands or the PRC would recognize or enforce judgments.

|B. | Business Overview
|-- | -----------------

Overview

We are an integrated solar-power products manufacturer based in China. Since we began our solar-power products business in 2004, we have integrated the
manufacture of monocrystalline ingots, wafers and solar cells for use in our solar module production. By the end of 2007, we expect to expand our platform to include the production of multicrystalline ingots, wafers and solar cells for use in our
solar module production. Our solar modules provide reliable and environmentally-friendly electric power for residential, commercial, industrial and other applications worldwide.

We produce standard solar modules ranging from 160 watts (W) to 185 W in power output. Our solar modules are built to general specifications as well
as to our customers specifications. We sell and market our products worldwide, including in a number of European countries, such as Germany, Spain and Italy, where government incentives have accelerated the adoption of solar power. We sell
most of our products to distributors, wholesalers and system integrators, including Corporación Zigor S.A., Scatec AS, SKR Energie GmbH, Schüco International KG, Conergy AG and Phönix SonnenStrom AG. Since our initial public
offering in December 2006, we have expanded into other European markets such as Spain and Italy and have added customers such as Enerpoint srl, Enercat, Enerpal and Ensol.

We address the industry-wide shortage of polysilicon by forging supply relationships with several global and domestic silicon distributors, silicon
manufacturers, semiconductor manufacturers and silicon processing companies. In addition, our experience and know-how in working with monocrystalline silicon have enabled us to use a higher proportion of low-cost, reclaimable silicon raw materials
in the production of ingots, as compared to other manufacturing methods generally used in the industry. We purchase polysilicon and reclaimable silicon materials from our network of over 20 suppliers and leverage our ability to use a higher
proportion of lower-cost reclaimable silicon materials, currently accounting for up to 80% of our total silicon requirements. We have entered into long-term supply contracts with polysilicon suppliers, including Wacker Chemie AG and DC Chemical, as
the industry-wide supply of polysilicon expands in line with current expectations. We also capitalize on our low-cost manufacturing capability in China to produce quality products at competitive costs.

As of December 31, 2006, we had an annual module manufacturing capacity of 59.8 megawatts (MW). We expect to increase our total annual production
capacity from ingots to solar modules to 150 MW by the end of 2007 and to 350 MW by the end of 2008. We currently use toll manufacturers by providing wafers to them and receiving solar cells from them in return. Such wafers are converted into solar
cells using the toll manufacturers own technology. From time to time, we also sell a portion of our ingots to toll manufacturers and



27

##### Table of Contents

purchase wafers from them in return. Toll manufacturing is a type of contract manufacturing frequently used in the solar power industry whereby part of the
manufacturing process is outsourced to qualified third parties, or toll manufacturers. The raw materials used by toll manufacturers are usually supplied by the originating company in order to control sourcing quality. To complete our vertical
integration strategy, we have built our own solar cell plant with an initial annual manufacturing capacity of 50 MW and have begun production of solar cells in April 2007.

We began our research and development efforts in solar products in 1999. In 2002, we began our system integration business, in late 2004 we began our
current solar module business, and in April 2007 we began our production of solar cells. In 2005 and 2006, we had net revenues of $27.3 million and $114.5 million, respectively, and net income of $3.2 million and $13.2 million, respectively, from
our continuing operations.

Products

We design, develop, manufacture and sell solar modules. Solar modules are arrays of interconnected solar cells encased in a weatherproof frame. We produce standard solar modules, ranging from 160 W to 185 W in power output, built to general
specifications for use in a wide range of residential, commercial, industrial and other solar power generation systems. This power output is slightly below the amount of power required for a typical 29-inch television set with a 200 W specification.
The variation in power output is based on the conversion efficiency of the cells used in our solar modules. We also design and produce solar modules based on our customers specifications. Our solar modules are sealed, weatherproof and able to
withstand high levels of ultraviolet radiation and moisture. We primarily sell our modules under our own brand.

Manufacturing

We manufacture ingots, wafers, cells and modules. Our facilities include ingot, wafer, cell and module production lines with the current annual
manufacturing capacity of 90 MW, 75.8 MW, 50 MW and 75 MW, respectively. The following table sets forth our manufacturing capacity and production output in MW equivalent of module production as a result of our ramp-up for each of our facilities.

| |  |  | Silicon feedstock. We purchase polysilicon and reclaimable silicon raw materials from various suppliers, including silicon distributors, silicon
manufacturers, semiconductor manufacturers and silicon processing companies. We test and categorize reclaimable silicon raw materials based on their technical properties. These reclaimable silicon raw materials then undergo mechanical grinding and
chemical cleaning before they are mixed using our proprietary formula. Our ability to mix the materials in the right proportion is critical to the production of high-quality silicon ingots.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Ingots. We began manufacturing ingots in August 2005 with pulling machines. As of December 31, 2006, we had 90 pulling machines with an aggregate annual
capacity of approximately 229.3 metric tonnes, which typically yields 90.0 MW of modules based on current manufacturing processes. In the first quarter of 2007, we added another 20 pulling machines and our ingot output can support an estimated
annual module capacity of 150 MW.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

To produce monocrystalline silicon ingots, silicon raw materials are first melted in a
quartz crucible in the pulling machine, which acts as a furnace. Then, a thin crystal seed is dipped into the melted material to determine the crystal orientation. The seed is rotated and then slowly extracted from the melted material which
solidifies on the seed to form a single crystal.

We intend to establish a platform for the production of multicrystalline ingots by the end
of 2007 and have purchased the necessary equipment, such as DSS (Directional Solidification System) furnaces, for its establishment. To produce multicrystalline ingots, silicon raw materials are first melted and cast into ingots. The resulting ingot
consists of multiple smaller crystals as opposed to the single crystal of a monocrystalline ingot.



| |  |  | Wafers. Currently, we slice silicon wafers to a 220 micron thickness, while maintaining a low breakage rate. We began manufacturing wafers in February 2006.
Ingots are squared and then sliced into wafers by high-precision cutting techniques using steel wires and silicon carbon powder. After being inserted into frames, the wafers go through a cleansing process to remove debris from the previous
processes, and are then dried. Wafers are inspected for contaminants and packed and shipped in boxes to solar cell manufacturers. Our annual wafer manufacturing capacity as of December 31, 2006 was approximately 32.4 million wafers, which
typically yields 75.8 MW of modules based on current manufacturing processes. We currently use toll manufacturers to produce a portion of our silicon wafers. We plan to increase our annual manufacturing capacity to approximately 66 million
wafers by the end of 2007 to meet our estimated annual module capacity of 150 MW.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Solar cells. We currently produce our own solar cells, as well as use toll manufacturers for use in our solar modules. In April 2007, we began production of
cells and have achieved an average conversion efficiency of 16.3%. We currently have two production lines with an annual manufacturing capacity of 50 MW and produce approximately 39,000 solar cells per day. We plan to increase our annual
manufacturing capacity to 150 MW by adding four additional lines by the end of 2007. Of the solar cell lines to be added by the end of 2007, we intend to add two lines, equal to approximately 50 MW of capacity, that are capable of producing
multicrystalline solar cells. We are targeting a conversion efficiency of approximately 15.5% for our multicrystalline solar cells.

To manufacture solar cells, the crystalline silicon wafer is used as the base substrate. After cleaning
and texturing the surface, emitter is formed through a diffusion process. The front and back sides of the wafer are then isolated using the plasma etching technique, the oxide formed during the diffusion process is removed and thus an electrical
field is formed. We then apply an anti-reflective coating to the surface of the cell using plasma enhanced chemical vapors to enhance the absorption of sunlight. The front and back sides of the cell are screen printed with metallic inks and the cell
then undergoes a fire treatment in order to preserve its mechanical and electrical properties. The cell is tested and classified according to its parameters.



| |  |  | Solar modules. We began module manufacturing in November 2004. We increased our annual manufacturing capacity of modules from 6 MW per year as of November
2004 to 59.8 MW per year as of December 31, 2006. We currently have eight production lines, and plan to increase our annual manufacturing capacity to 150 MW by adding six additional lines by the end of 2007.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

To assemble solar modules, we interconnect multiple solar cells by taping and stringing the cells into a desired electrical configuration. The
interconnected cells are laid out, laminated in a vacuum, cured by heating and then packaged in a protective light-weight aluminum frame. Through this labor-intensive process, our solar modules are sealed and become weatherproof and are able to
withstand high levels of ultraviolet radiation and moisture.

Solar module assembly remains a labor intensive process. We leverage
Chinas lower labor costs by using a greater degree of labor in our manufacturing process when it proves to be more efficient and cost-effective than using equipment. We are in close proximity to Chinese solar equipment manufacturers that offer
many of the solar manufacturing equipment we require at competitive prices compared to most similar machinery offered by international solar equipment manufacturers.

Silicon Raw Material Supplies

Our business depends on our ability to obtain silicon raw materials,
including polysilicon, reclaimable silicon raw materials and, from time to time, ingots. We procure polysilicon from international manufacturers as well as international and domestic distributors, and purchase reclaimable silicon raw materials from
over 20 suppliers, including semiconductor manufacturers and silicon processing companies.

We have three procurement offices located in
Asia and Europe. We believe our procurement teams geographical proximity to the supply sources helps us better communicate with the suppliers and respond to them more efficiently. We believe our efforts to procure silicon raw materials from
various sources will enable us to better control the silicon supply chain, increase manufacturing efficiency, and reduce margin pressure.

We have secured approximately 90% of our silicon raw material requirements to support our estimated production output in 2007 and 60% of our silicon raw material requirements in 2008. Most of this supply has been secured through one to
three year medium-term contracts with polysilicon manufacturers, semiconductor companies and silicon reclamation companies. In addition, we are in active discussions with our suppliers to secure the rest of our silicon raw material requirements
needed for our production output in 2007.

##### Table of Contents

We intend to leverage the global reach of our procurement personnel to secure the remainder of our silicon requirements. In January and February 2007, we
entered into two long-term contracts for the procurement of polysilicon with Wacker Chemie AG and DC Chemical, respectively. The shipments are expected to begin in 2009.

We believe that current polysilicon shortages may ease due the establishment of new polysilicon projects and the expansion of capacity in existing manufacturers. Our focus is to work closely with the new or expansion
projects that we have identified as projects with the highest likelihood of success.

Solar Cell Supplies

We have historically purchased solar cells from third-party solar cell manufacturers. After we installed our monocrystalline ingot and wafer production
lines, we began manufacturing silicon raw materials into ingots and wafers in-house, and outsourcing the fabrication of solar cells to solar cell manufacturers. We have developed collaborative relationships with various international and domestic
manufacturers of solar cells, including Suntech Power Holdings Co., Ltd., Q-Cells AG, Motech Industries, Inc. and DelSolar Co., Ltd. To reduce our dependence on third-party solar cell manufacturers and to increase our efficiencies both in solar cell
technology and solar module manufacturing, we began production of cells in April 2007. We currently have two production lines with an annual manufacturing capacity of 50 MW and produce approximately 39,000 solar cells per day. We plan to increase
our annual manufacturing capacity to 150 MW by adding four additional lines by the end of 2007. In addition, in December 2006, we entered into a strategic cooperation agreement with Q-Cells AG, pursuant to which Q-Cells AG agreed to provide
technical assistance to us during the ramp-up phase of our solar cell production lines. We also agreed to supply Q-Cells AG with a certain amount of high-quality monocrystalline wafers to be processed into high efficiency cells for our module
assembly facility.

From time to time, we purchase monocrystalline ingots, wafers or cells not manufactured under toll arrangements to take
advantage of favorable market conditions or to meet any of our production requirements. We expect to discontinue purchasing solar cells from toll manufacturers by late 2007, when our solar cell manufacturing output capacity is expected to be in line
with our ingot, wafer and module manufacturing output capacity.

Quality Assurance

Our quality control was set up according to the quality system requirements of ISO 9001:2000. Our quality control consists of three components: incoming
inspection through which we ensure the quality of the raw materials that we source from third parties, in-process quality control of our manufacturing processes, and output quality control of finished products through inspection and conducting
reliability and other tests.

We have received international certifications for our quality assurance programs, including
ISO 9001:2000, which we believe demonstrate our technological capabilities as well as instill customer confidence. The following table sets forth the major certifications we have received and major test standards our products have met as of the
date of this annual report.

Customers and Markets

We currently sell our solar modules primarily to distributors, wholesalers and system integrators. Some of the system integrators also resell our modules to other system integrators. Our customers typically design and
sell integrated systems that include our branded solar modules along with other system components. Our major customers for 2006 included Corporación Zigor S.A., Scatec AS, SKR Energie GmbH, Schüco International KG, Conergy AG and
Phönix SonnenStrom AG.

A small number of customers have historically accounted for a majority of our net sales. The top five of our
customers collectively accounted for approximately 59.1% and 48.9% of our net revenues in 2005 and 2006, respectively. Each of Inowatt Elektro Technik GmbH and Soleko GmbH contributed over 10% of our net revenues for 2005. Each of Corporación
Zigor S.A. and Scatec AS contributed over 10% of our net revenues for 2006.

We currently sell most of our solar modules to customers
located in Europe. Solar manufacturers like us have capitalized on the government and regulatory policies for the promotion of solar power in many jurisdictions. In order to continue growing our sales and to reduce our exposure to any particular
market segment, we intend to broaden our geographic presence and customer base. While Germany continues to be a major market for us, we have significantly expanded our sales of solar modules to several solar power markets, including Spain and Italy.
Since our initial public offering in December 2006, we have expanded into other European markets such as Spain and Italy and have added customers such as Enerpoint srl, Enercat, Enerpal and Ensol. In May 2007, we progressed towards some of our
previously stated sales and marketing objectives by signing several agreements with well-recognized companies in Spain and Italy. One of the contracts represents a commitment to supply a range of 80 to 150 MW to Ibersolar of Spain from 2007 to 2010.
These new contracts are in line with our goals of increasing our market presence in Europe outside of Germany and building a brand as one of the top global solar products companies.

In the first quarter of 2007, sales to Spain, Italy and Germany consisted of approximately 34.3%,
24.3%, and 13.4% of our total net revenues, respectively. Germany accounted for a smaller percentage of our total net revenues due to slower demand for solar power products in such market during the winter season.

Many of our solar module sales are conducted via short-term purchase orders placed by our customers. We sometimes enter into long-term sales contracts
with terms of three years under which we are obligated to sell our products at a set price during the term of the contract. In the past, given the strong industry demand for solar modules and increases in average selling price per watt, the
short-term nature of our contractual arrangements allowed us to benefit from the price increases. Depending on the credit status of our customers, market demand and the term of the contracts, we generally require our customers to make a prepayment,
with the remaining balance to be paid within 30 days after shipment.

As we plan to enhance our relationship with our key customers, we
intend to enter into longer term sales contracts with flexible pricing in order to secure demand for our solar modules.

Pursuant to our
sales contracts, we provide customers with warranty services. Our solar modules are typically sold with a two-year warranty for defects in material and workmanship and a minimum power output warranty for up to 25 years following the date of purchase
or installation.

Sales and Marketing

We market and sell our solar power products primarily to distributors, wholesalers and system integrators, such as Enerpoint srl and Enerpal. Most of our sales personnel are based in Changzhou, China, and five of our employees are located
in Europe. Our marketing programs include industry conferences, trade fairs and public relations events. Our sales and marketing group works closely with our research and development and manufacturing groups to coordinate our product development
activities, product launches and ongoing demand and supply planning. We have near-term plans to expand our sales network by establishing offices in Europe and the United States dedicated to regional sales.

##### Table of Contents

Intellectual Property

In manufacturing our solar power products, we use know-how available in the public domain and unpatented know-how developed in-house. We rely on a combination of trade secrets and employee contractual protections to
establish and protect our proprietary rights. We believe that many elements of our solar power products and manufacturing processes involve proprietary know-how, technology or data that are not covered by patents or patent applications, including
technical processes, equipment designs, algorithms and procedures. We have taken security measures to protect these elements. Substantially all of our research and development personnel have entered into confidentiality, non-competition and
proprietary information agreements with us. These agreements address intellectual property protection issues and require our employees to assign to us all of their inventions, designs and technologies they develop during their terms of employment
with us.

As of December 31, 2006, we had 15 issued patents and three patent applications pending in China. In general, most of our
issued patents relate to technology that we do not use in our current production of solar power products, while some of our issued patents and our pending patent applications relate to technology that we are going to use, including technology
relating to integration of construction elements into our solar modules or solar systems. As we expand our product portfolio and enter into solar cell manufacturing in the future, we believe that the development and protection of our intellectual
property will become more important to our business. We intend to continue to assess appropriate opportunities for patent protection of those aspects of our technology that we believe provide significant competitive advantage to us.

Competition

The market for solar power products is
competitive and fast evolving. We expect to face increasing competition, which may result in price reductions, reduced margins or loss of market share. We believe that the key competitive factors in the market for solar modules include:



| |  |  | manufacturing efficiency;
| | - |  | -------------------------



| |  |  | power efficiency and performance;
| | - |  | ---------------------------------



| |  |  | price;
| | - |  | ------



| |  |  | strength of supplier relationships;
| | - |  | -----------------------------------



| |  |  | aesthetic appearance of solar modules; and
| | - |  | ------------------------------------------



| |  |  | brand name and reputation.
| | - |  | --------------------------

We
compete with other module manufacturing companies such as Yingli Green Energy Holding Co., Ltd., BP Solar International Inc., ErSol Solar Energy AG, Suntech Power Holdings Co., Ltd. and Sunways AG. Some of our competitors also manufacture and supply
us with solar cells. We believe one of our key advantages over some of these competitors is our high degree of vertical integration, which will be further strengthened with the completion of our proposed solar cell plant. Some of our competitors
have also become vertically integrated, from silicon wafer manufacturing to solar power system integration, such as Renewable Energy Corporation ASA and SolarWorld AG. Many of our competitors have a stronger market position than ours and have
greater resources and better brand recognition than we have. Further, many of our competitors are developing and are currently producing products based on new solar power technologies, such as thin-film technology, which may ultimately have costs
similar to, or lower than, our projected costs.

##### Table of Contents

We may also face new competition from semiconductor manufacturers, several of which have already
announced their intention to start production of solar cells. If we fail to compete successfully, we may be unable to expand our customer base and our business would suffer.

In the immediate future, because of the growing demand for solar power products, shortage of polysilicon and rising cost of silicon raw materials, we
believe that the competitive arena will increasingly center around securing silicon supply and forming strategic relationships to secure supply of key components and technologies. Consolidation of the segments of the solar industry supply chain is
already occurring and will continue. We believe that should the supply of silicon stabilize while the demand for modules remains strong, the key to competing successfully will shift to more traditional marketing and sales activities, and strong
relationships that we are currently building will support us in the new competitive environment.

Environmental Matters

We believe we have obtained all of the environmental permits necessary to conduct our business. Our manufacturing processes generate noise, waste water,
gaseous wastes and other industrial wastes. However, we have devoted efforts to reduce such wastes to acceptable levels. We have installed various types of anti-pollution equipment in our facilities to reduce, treat, and where feasible, recycle the
wastes generated in our manufacturing process. We believe we are currently in compliance with all applicable environmental laws and regulations. Our operations are subject to regulation and periodic monitoring by local environmental protection
authorities. If we fail to comply with present or future environmental laws and regulations, we could be subject to fines, suspension of production or a cessation of operations.

Insurance

We maintain property insurance policies with reputable insurance companies for covering
our equipment, facilities, buildings and their improvements, and office furniture. These insurance policies cover losses due to fire, earthquake, flood and a wide range of other natural disasters. We maintain director and officer liability insurance
for our directors and executive officers. We do not maintain product liability insurance. We consider our insurance coverage to be in line with other manufacturing companies of similar size in China. However, significant damage to any of our
manufacturing facilities, whether as a result of fire or other causes, could have a material adverse effect on our results of operation. We paid an aggregate of approximately $13,000 and $62,000 in insurance premiums in 2005 and 2006, respectively,
for insurance coverage up to October 2007. The increase in premium was largely due to an increase in the scope of our insurance coverage, including our purchase of business interruption insurance.

Renewable Energy Law and Other Government Directives

In February 2005, China enacted its Renewable Energy Law, which became effective on January 1, 2006. The Renewable Energy Law sets forth policies to
encourage the development and use of solar energy and other non-fossil energy. The renewable energy law sets forth the national policy to encourage and support the use of solar and other renewable energy and the use of on-grid generation. It also
authorizes the relevant pricing authorities to set favorable prices for the purchase of electricity generated by solar and other renewable power generation systems.

The law also sets forth the national policy to encourage the installation and use of solar energy water-heating systems, solar energy heating and cooling systems, solar photovoltaic systems and other solar energy
utilization systems. It also provides financial incentives, such as national funding, preferential loans and tax preferences for the development of renewable energy projects. In January 2006, Chinas National Development and Reform Commission
promulgated two implementation directives of the Renewable Energy Law. These directives set forth specific measures in setting prices for electricity generated by solar and other renewal power generation systems and in sharing additional expenses
occurred. The directives further allocate the administrative and supervisory authorities among different government agencies at the national and provincial levels and stipulate responsibilities of electricity grid companies and power generation
companies with respect to the implementation of the Renewable Energy Law.

Chinas Ministry of Construction also issued a directive in
June 2005, which seeks to expand the use of solar energy in residential and commercial buildings and encourages the increased application of solar energy in different townships. In addition, Chinas State Council promulgated a directive in July
2005 which sets forth specific measures to conserve energy resources.

Environmental Regulations

We are subject to a variety of governmental regulations related to environmental protection. The major environmental regulations applicable to us include
the Environmental Protection Law of the PRC, the Law of PRC on the Prevention and Control of Water Pollution, Implementation Rules of the Law of PRC on the Prevention and Control of Water Pollution, the Law of PRC on the Prevention and Control of
Air Pollution, Implementation Rules of the Law of PRC on the Prevention and Control of Air Pollution, the Law of PRC on the Prevention and Control of Solid Waste Pollution, and the Law of PRC on the Prevention and Control of Noise Pollution.

Restriction on Foreign Ownership

The principal regulation governing foreign ownership of solar power businesses in the PRC is the Foreign Investment Industrial Guidance Catalogue (effective as of January 1, 2005), or Catalogue. The Catalogue classifies the various
industries into four categories: encouraged, permitted, restricted and prohibited. As confirmed by the government authorities, Trina China, our operating subsidiary, is engaged in an encouraged industry. Trina China is permitted under the PRC laws
to be wholly owned by a foreign company. Trina China is, accordingly, also entitled to certain preferential treatment granted by the PRC government authorities, such as exemption from tariffs on equipment imported for its own use.

Tax

PRC enterprise income tax is calculated primarily on the basis of taxable income determined under PRC accounting principles. In accordance with Income Tax Law of China for Enterprises with Foreign Investment and Foreign Enterprises, or the
Income Tax Law, and the related implementing rules, foreign invested enterprises incorporated in the PRC are generally subject to an enterprise income tax of 30% and a local income tax of 3%. The Income Tax Law and the related implementing rules
provide certain preferential favorable tax treatments to foreign invested enterprises which qualify as advanced technological enterprises or are established in certain areas in the PRC.

In 2002, Trina China relocated to a high-tech zone in Changzhou, and as a high and new technology enterprise, it qualified for a preferential
enterprise income tax rate of 15% in 2002 and 2003. As a foreign invested enterprise engaged in a manufacturing business, Trina China was also entitled to a two-year exemption from the enterprise income tax for its first two profitable years of
operation, which were 1999 and 2000, and to a 50% reduction of its applicable income tax rate for the succeeding three years, which were from 2001 to 2003. Therefore, Trina China had a tax rate of 7.5% in each of 2002 and 2003. In 2004, Trina China
moved out of the high-tech zone and no longer qualified for a preferential enterprise income tax rate of 15%. Trina China, a foreign invested enterprise engaged in a manufacturing business and established in Changzhou, which is within a coastal
economic zone, is entitled to a preferential enterprise income tax rate of 24%. In addition, Trina China was qualified as an advanced technological enterprise and, as a result, enjoyed a preferential enterprise income tax rate of 12% for
the years 2004 to 2006. As the tax benefit for an advanced technological enterprise expired in 2006, the tax rate of Trina China has increased to 27% (24% enterprise income tax plus 3% local income tax) in 2007. However, because income
from incremental investment to the registered capital of a foreign invested enterprise is entitled to a two-year exemption and a 50% reduction of the applicable income tax rate for the succeeding three years, and Trina Chinas registered
capital was increased from $7.28 million to $40 million, Trina China is eligible for an income tax exemption for 81.8% of its income from August 2006 to December 2007. 18.2% of Trina Chinas income remains subject to a tax rate of 27% starting
from January 2007. In addition, Chinas parliament, the National Peoples Congress, adopted the Enterprise Income Tax Law on March 16, 2007. This new tax law will replace the existing separate income tax laws for domestic enterprises
and foreign-invested enterprises and become effective on January 1, 2008. Under the new tax law, a unified enterprise income tax rate is set at 25% for both domestic enterprises and foreign-invested enterprises. However, there will be a
five-year transition period for foreign-invested enterprises. In addition, an enterprise that enjoys a preferential tax treatment for a fixed term may continue to enjoy such treatment until the fixed term expires. During the transition period, Trina
China will be allowed to continue to enjoy the existing preferential tax treatment. In addition, under the new tax law, a resident enterprise, which includes an enterprise established outside of China with management located in China,
will be subject to PRC income tax. If the PRC tax authorities subsequently determine that Trina should be deemed a resident enterprise, then Trinas global income will be subject to PRC income tax at a tax rate of 25%. The exemption to the 20%
withholding tax on dividends distributed by foreign-invested enterprises to their foreign investors under the current tax laws may no longer be available under the new tax law. Since the new law has only been adopted recently, there is uncertainly
as to how it should be interpreted or implemented.

Pursuant to the Provisional Regulation of China on Value Added Tax and its implementing
rules, all entities and individuals that are engaged in the sale of goods, the provision of processing, repairs and replacement services and the importation of goods in

##### Table of Contents

China are generally required to pay value added tax, or VAT, at a rate of 17.0% of the gross sales proceeds received, less any deductible VAT already paid or
borne by the taxpayer. Further, when exporting goods, the exporter is entitled to a portion or all of the refund of VAT that it has already paid or borne. Imported raw materials that are used for manufacturing export products and are deposited in
bonded warehouses are exempt from import VAT.

Foreign Currency Exchange

The principal regulation governing foreign currency exchange in China is the Foreign Exchange Administration Regulations (1996), as amended. Under the
Regulations, Renminbi is freely convertible for current account items, including the distribution of dividends, interest payments, trade and service-related foreign exchange transactions, but not for capital account items, such as direct investment,
loan, repatriation of investment and investment in securities outside China, unless the prior approval of the State Administration for Foreign Exchange of China, or SAFE, is obtained.

Pursuant to the Administration Rules of the Settlement, Sale and Payment of Foreign Exchange (1996), foreign invested enterprises in China may purchase
and/or remit foreign exchange, subject to a cap approved by the SAFE, for settlement of current account transactions without the approval of the SAFE. Foreign exchange transactions under the capital account are still subject to limitations and
require approvals from, or registration with, the SAFE and other relevant PRC governmental authorities.

Dividend Distribution

The principal regulations governing distribution of dividends of wholly foreign-owned enterprises include the Wholly Foreign-owned Enterprise Law (1986),
as amended by the Decision on Amending the Law of the Peoples Republic of China on Wholly Foreign-owned Enterprise (2000), and the Implementing Rules of the Wholly Foreign-owned Enterprise Law (1990), as amended by the Decision of the State
Council on Amending the Implementing Rules of the Law of the Peoples Republic of China on Wholly Foreign-owned Enterprise (2001).

Under these regulations, foreign invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with Chinese accounting standards and regulations. In addition, wholly foreign owned
enterprises in China are required to set aside at least 10% of their respective after-tax profits based on PRC accounting standards each year, if any, to fund its general reserves fund, until the accumulative amount of such reserves reaches 50% of
its registered capital. These reserves are not distributable as cash dividends. Wholly foreign owned enterprises are also required to allocate a portion of its after-tax profits, as determined by its board of directors, to its staff welfare and
bonus funds, which may not be distributed to equity owners.

In addition, under a new PRC tax law to be effective in January 2008,
dividends from Trina China to us may become subject to a 20% withholding tax. See RegulationTax.

|A. | Operating Results
|-- | -----------------

Overview

Our net revenues have increased rapidly in recent years. In 2006, our net revenues were $114.5 million compared to $27.3 million in 2005. Our net revenues
increased primarily due to our increased manufacturing capacity as demand for our products remained strong. In addition, our gross margins during those periods improved from 23.1% to 26.2%, and we recorded net income from continuing operations of
$13.2 million in 2006 compared to net income of $3.2 million in 2005. Our gross margins and net income improved as the average selling prices of our products increased and as we enhanced vertical integration and achieved greater economies of scale,
which partially offset by higher silicon raw material costs.

The most significant factors that affect the financial performance and
results of operations of our solar products business are:

Industry
Demand

Our business and revenue growth depends on market demand for solar power. Although solar power technology has been used for
several decades, the solar power market has only grown significantly in the past several years. According to Photon Consulting, the global solar power market, as measured by annual solar power production, increased by 41.7% from 1.2 GW in 2004 to
1.7 GW in 2005. During the same period, solar power industry revenues grew from approximately $8 billion in 2004 to approximately $12 billion in 2005. Photon Consulting projects that solar power industry revenues and solar power production will
reach $72 billion and 10.4 GW, respectively, by 2010. Solar power production is expected to grow at a CAGR of 43.7% from 2005 to 2010, driven largely by rising grid prices, government initiatives and new distribution channels, according to Photon
Consulting.

Government Subsidies and Economic Incentives

We believe that the near-term growth of the market for on-grid applications depends in large part on the availability and size of government subsidies and
economic incentives. Today, the cost of solar power substantially exceeds the cost of power provided by the



40

##### Table of Contents

electric utility grid in many locations, when upfront system costs are factored into cost per kilowatt. As a result, governmental bodies in many countries,
most notably Germany, Spain, Italy, the United States, Japan and China, have provided subsidies and economic incentives to reduce dependency on non-renewable sources of energy. These subsidies and economic incentives have come in the form of capital
cost rebates, feed-in tariffs and tax credits and other incentives to end users, distributors, system integrators and manufacturers of solar power products. The demand for our solar modules in our targeted or potential markets is affected
significantly by these government subsidies and economic incentives.

Availability and Price of Polysilicon and Reclaimable Silicon
Raw Materials

Reclaimable silicon raw materials are essential raw materials for our business. Our proprietary process technology
allows us to use a higher proportion (currently approximately 80%) of reclaimable silicon raw materials in the production of monocrystalline silicon ingots. The costs of these reclaimable silicon raw materials have historically been significantly
less than the costs of polysilicon. However, due to the solar power industrys growing demand for reclaimable silicon raw materials, prices of these reclaimable silicon raw materials are also increasing. We currently purchase reclaimable
silicon raw materials from over 20 suppliers, including semiconductor manufacturers and silicon processing companies. Moreover, we are currently in discussions with other China-based semiconductor manufacturers to secure additional reclaimable
silicon raw materials.

For the procurement of reclaimable raw materials, we enter into short-term contracts with terms of no more than six
months each. The contracts provide for a fixed price and fixed amount and generally require prepayment prior to shipment. Most of the contracts give us the right to reject any shipment by our suppliers that does not meet our quality standards based
on usability and resistivity of the materials. The contracts also specify a time period during which we can inspect the goods to ensure their quality.

Increases in the price of polysilicon have in the past increased our production costs and may impact our cost of revenues and net income. According to Solarbuzz, the average long-term supply contract price of
polysilicon increased from approximately $35-$40 per kilogram delivered in 2005 to $50-$55 per kilogram delivered in 2006, and is expected to increase to $60-$65 per kilogram delivered in 2007. In addition, according to Solarbuzz, spot prices for
incremental supplies of polysilicon, in some cases, reached $300 per kilogram in 2006. Based on our experience, we believe that the average price of polysilicon will continue to remain high or increase in the foreseeable future until a significant
portion of polysilicon manufacturing capacity currently under construction becomes available. Any increase in demand from the semiconductor industry will exacerbate the shortage.

We purchase polysilicon mostly from silicon distributors and silicon manufacturers. For procurement of polysilicon, we enter into short-term, medium-term
and long-term contracts. Our short-term contracts have terms of no more than one-year each. The contracts provide for a fixed price and fixed amount and generally require prepayment prior to shipment. Most of the contracts give us the right to
reject any shipment by our suppliers that does not meet our quality standards based on grade levels, such as semiconductor grade or solar grade, of the polysilicon. The contracts also specify a time period during which we can inspect the goods to
ensure their quality. Our medium-term contracts have terms ranging from one to three years, and our long-term contracts have terms ranging from five to ten years. These contracts generally have a fixed amount and fixed price subject to adjustments
or variable price. These contracts generally require us to make an advance payment of a



41

##### Table of Contents

certain negotiated amount. In 2009, some of our medium-term and long-term contracts will become increasingly important as the suppliers will be required to
perform under their silicon wafer supply commitment to us. In January and February 2007, we entered into two long-term contracts for the procurement of polysilicon with Wacker Chemie AG and DC Chemical, respectively. The shipments under those
contracts are expected to begin in 2009.

Given the current state of the industry, suppliers of polysilicon and reclaimable silicon raw
materials typically require customers to make payments in advance of shipment. Our suppliers generally require us to make a prepayment at a certain percentage of the order value prior to shipping. As a result, the purchase of silicon raw materials
has required, and will continue to require, us to make significant working capital commitments beyond the capital generated from our cash flows from operations. We are required to manage our borrowings and equity contributions to support our
purchases of raw materials.

Vertically Integrated Manufacturing Capabilities

We believe that our vertical integration strategy has allowed us, and will continue to allow us, to capture value throughout the solar power value chain,
achieve better quality control of our products and realize synergistic cost savings. As part of our vertical integration efforts, we began manufacturing silicon ingots in August 2005 and wafers in February 2006. We began to use toll manufacturers in
August 2005 to produce solar cells for our modules. As our current wafer output is insufficient to meet our wafer requirements, we also sell a portion of our ingots to toll manufacturers and purchase wafers from them in return.

Depending on prevailing market prices of silicon raw materials, from time to time, we purchase ingots from ingot manufacturers to take advantage of
favorable market prices relative to other silicon raw materials. We also purchase wafers and cells, from time to time, to supplement any shortfalls we have with respect to our production capacity or to take advantage of favorable market conditions.
As a result, we have developed relationships with various international and domestic suppliers of ingots, wafers and solar cells.

To
further our vertical integration strategy, we began production of solar cells in April 2007, which we expect will enhance our margins. Our vertically integrated business model allows us to reduce excess costs, such as those associated with packaging
and transportation, and the breakage loss that occurs during shipment between various production locations associated with toll manufacturing.

Product Pricing

We began selling our solar module products in November 2004. Our solar modules are priced based on
the number of watts of electricity they generate as well as the market price per watt for solar modules. We price our standard solar modules based on the prevailing market prices at the time we enter into sales contracts with our customers or our
customers place their purchase orders with us, taking into account the size of the contract or the purchase order, the strength and history of our relationship with each customer, and our silicon raw materials costs. Over the past few years, the
average selling prices for standard solar modules have risen year-to-year across the industry primarily because of high demand and rising polysilicon costs. Correspondingly, the average selling price of our standard solar module products increased
from $3.45 in 2004 to $4.02 in 2005 but decreased slightly to $3.98 in 2006. There are indications that the solar energy market and industry have been experiencing a price decrease in solar modules since the second half of 2006. Our business

may be materially and adversely affected if such trend continues. See Item 3. Key InformationD. Risk FactorsRisks Related to Our Company
and Our IndustryWe may be adversely affected by volatile market and industry trends, such as the recent decrease in the price of solar modules for more details.

Most of our solar module sales are conducted via short-term purchase orders placed by our customers. We sometimes enter into short-term sales contracts
with terms of three to six months with our customers under which we are obligated to sell our products at a set price during the term of the contract. Given the strong industry demand for solar modules and increases in average selling price per watt
in the past, the short-term nature of our contractual arrangements had allowed us to benefit from price increases which helped to offset higher polysilicon costs. Our sales contracts typically require our customers to make a prepayment depending on
the credit status of our customers, market demand and the term of the contracts, with the remaining price to be paid within 30 days after shipment. As we plan to enhance our relationship with key customers, we intend to enter into longer-term sales
contracts with variable pricing in order to secure demand for our solar modules

Overview of Financial Results

We evaluate our business using a variety of key financial measures.

Net Revenues

Our net revenues are net of business tax, value-added tax and returns and
exchanges. We began to generate net revenues from the sales of solar modules in November 2004. We also generated revenues from our solar power system integration business in 2003 and 2006. Factors affecting our net revenues include average selling
price per watt, unit volume shipped and product demand for our solar modules.

In 2005 and 2006, sales to our top five customers accounted
for approximately 59.1% and 48.9% of our net revenues, respectively, and sales to our largest customer accounted for 20.6% and 14.4% of our net revenues, respectively. We currently sell most of our solar modules to customers located in Europe, in
particular Germany. The following table sets forth our total net revenues by geographical region for the periods indicated:

##### Table of Contents

In the first quarter of 2007, sales to Spain, Italy and Germany consisted of approximately 34.3%, 24.3%,
and 13.4% of our total net revenues, respectively. Germany accounted for a smaller percentage of our total net revenues due to slower demand for solar power products in such market during the winter season.

Cost of Revenues

Our cost of
revenues consists primarily of:



| |  |  | Silicon raw materials. Silicon raw materials comprise the majority of our cost of revenues. We purchase polysilicon and reclaimable silicon raw materials
from various suppliers, including silicon distributors, silicon manufacturers, semiconductor manufacturers and silicon processing companies.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Other direct materials for solar modules. Such materials include direct materials for the production of solar modules such as plastic, metallic pastes,
tempered glass, laminate material, connecting systems and aluminum frames.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Toll manufacturing. We enter into toll manufacturing arrangements by providing wafers to toll manufacturers and receiving solar cells from them in return.
The toll manufacturing cost is recorded as a part of our cost of revenues. As our wafer output is not sufficient to meet all of our wafer requirements, currently we also sell a portion of our ingots to toll manufacturers and purchase wafers from
them in return. Before we established our current ingot and wafer manufacturing capabilities, we recorded the purchase price of the solar cells, as opposed to the toll manufacturing cost, as part of our cost of revenues.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Overhead. Overhead costs include equipment maintenance and utilities such as electricity and water used in manufacturing.
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | Direct labor. Direct labor costs include salaries and benefits for our manufacturing personnel.
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | Depreciation of facilities and equipment. Depreciation of manufacturing facilities and related improvements is provided on a straight-line basis over the
estimated useful life of 20 years and commences from the date the facility is ready for its intended use. Depreciation of manufacturing equipment is provided on a straight-line basis over the estimated useful life of five to ten years, commencing
from the date that the equipment is placed into productive use.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Solar power system integration. Our cost of revenues for system integration includes solar modules, batteries, inverters, electronic components, supporting
structures, other related construction materials and labor.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Gross Margin

Our gross margin is affected by changes in our net revenues and cost of revenues. Our net revenues are determined by the average selling prices of our
products as well as the number of units of our products that we are able to sell. Our cost of revenues is affected by our ability to control raw material costs, to achieve economies of scale in our operations, and to efficiently manage our supply
chain, including our successful execution of our vertical integration strategy and our judicious use of toll manufacturers to fill potential shortfalls in production capability along the supply chain.



44



---

##### Table of Contents

Our gross margins increased from 23.1% in 2005 to 26.2% in 2006, despite increases in silicon raw
material prices. We were able to improve our gross margins as the average selling price of our solar modules increased and as we became more fully vertically integrated with the production of ingots beginning in August 2005 and wafers beginning in
February 2006. Moreover, we achieved higher manufacturing efficiencies and greater economies of scale as we expanded production output of solar modules from 6.8 MW in 2005 to 27.4 MW in 2006.

We may face margin compression in the sales of solar modules due to the increase in the market price of polysilicon and if we are unable to increase our
average selling price of solar modules due to market pressure to reduce the price per watt in order to achieve grid parity. However, we have been able to alleviate some of the margin pressure by manufacturing ingots using a higher proportion of
reclaimable silicon materials. Furthermore, we believe that as our solar module business expands, additional economies of scale and successful execution of our vertical integration strategy will improve our margins.

We intend to enhance our margin by completing our vertical integration, including operating a solar cell manufacturing facility. Achieving our vertical
integration strategy will allow us to reduce excess costs, such as those associated with packaging and transportation, and the breakage loss that occurs during shipment between various production locations associated with toll manufacturing.

Operating Expenses

Our operating expenses include selling expenses, general and administrative expenses and research and development expenses.

Selling Expenses

Selling expenses consist primarily of provisions for product warranties, travel and entertainment
expenses, freight expenses, employee salaries, pensions and other sales and marketing expenses. In 2006, we recognized a one-time share-based compensation expense in connection with the transfer of beneficial interests in our company to our
marketing personnel, as well as share-based compensation expenses in connection with our grants of restricted shares to employees. Our selling expenses have increased since 2004 primarily due to a warranty provision for solar modules that was
established in 2005 and will be included in our selling expenses going forward. Our solar modules are typically sold with a two-year warranty for defects in material and workmanship and a minimum power output warranty of up to 25 years following the
date of purchase or installation. We accrue the estimated cost of warranty based on 1% of the revenues generated from solar modules, consistent with the average industry level. Our selling expenses, excluding share-based compensation expense, as a
percentage of net revenues decreased between 2004 and 2005 primarily due to a significant increase in net revenues driven by high market demand for our products, and slightly increased between 2005 and 2006. We expect our selling expenses, excluding
share-based compensation expense, to increase in the near term as we increase our sales efforts, hire additional sales personnel, target new markets, establish representative offices and initiate additional marketing programs to build our brand.

##### Table of Contents

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and benefits for our administrative and finance personnel, bad debt provision,
amortization of land use rights and travel and entertainment expenses. In 2006, we recognized a one-time share-based compensation expense in connection with the transfer of beneficial interests in our company to our administrative personnel, as well
as share-based compensation expenses in connection with our grants of restricted shares to employees. Our general and administrative expenses have increased since 2004, primarily due to increases in the number of our administrative employees as well
as their salaries and benefits. Our provision for uncollectible accounts has remained immaterial since 2004 as we have not had significant collection issues for receivables generated from our solar module business. We expect our general and
administrative expenses, excluding share-based compensation expense, to increase as we hire additional personnel and incur expenses to support our operations as a public company, including compliance-related costs. However, we expect our general and
administrative expenses to decrease as a percentage of net revenues as we achieve greater scale.

Research and Development Expenses

Research and development expenses consist primarily of costs of raw materials used in our research and development activities, salaries and
benefits for research and development personnel and prototype and equipment costs relating to the design, development, testing and enhancement of our products and manufacturing process. In 2006, we recognized a one-time share-based compensation
expense in connection with the transfer of beneficial interests in our company to our research and development personnel, as well as share-based compensation expenses in connection with our grants of restricted shares to employees. In late 2004, we
disposed of our research and development subsidiary, Tianhe Research Institute Co., Ltd., or Tianhe Research, and in 2005 we received an annual research grant from the PRC government of an amount greater than that we received in 2004. Both of these
events led to decreases in research and development expenses in 2005. Between 2005 and 2006, our research and development expenses increased significantly due to investment in solar cell technology in preparation of ramping up our solar cell
production in April 2007. We expect our research and development expenses, excluding share-based compensation expense, to increase as we hire additional research and development personnel, expand and promote innovation in our process technologies of
manufacturing monocrystalline ingots, wafers, cells and solar modules. We will continue to devote efforts to improve our technical know-how to produce monocrystalline ingots and wafers by using a higher proportion of reclaimable silicon raw
materials. Moreover, as we continue to generate more reclaimable silicon from our own processes, we intend to establish a platform to use reclaimable silicon that we have identified as better suited and more cost-effective to be used for
multicrystalline silicon production processes. Therefore, we will devote some of our research and development resources to develop such platform in order to improve our production efficiency.

Share-based Compensation Expenses

We adopted our 2006 share incentive plan in July 2006 and have granted a total of 45,725,760 restricted shares as of December 31, 2006. For a description of the restricted shares granted, including the exercise prices and vesting
periods thereof, see Item 6. Directors, Senior Management and EmployeesB. Compensation of Directors and Executive Officers2006 Share Incentive Plan. Under Statement of Financial Accounting Standards No. 123(R),
Share-Based Payment, we are required to recognize share-based compensation as compensation expense in our statement of operations based on the fair value of equity awards

on the date of the grant, with the compensation expense recognized over the period in which the recipient is required to provide services to us in exchange
for the equity award. For restricted shares granted to our employees, we record share-based compensation expense for the excess of the fair value of the restricted shares at the date of the grant over the purchase price that a grantee must pay to
acquire the shares during the period in which the shares may be purchased. We have categorized these share-based compensation expenses in our (i) cost of revenues; (ii) selling expenses; (iii) general and administrative expenses; and
(iv) research and development expenses, depending on the job functions of the grantees of our restricted shares.

In 2006, we
transferred certain beneficial interests of our Company to our employees and granted the following restricted shares to our employees.



|                |  |                                                                  |  |                                     |  |                                       |

Discontinued Operations

Prior to June 30, 2006, we were engaged in the aluminum siding business, which included the production, marketing and sale of aluminum exterior wall products used for cladding the exteriors of buildings and
houses. On June 28, 2006, our board of directors resolved to discontinue our aluminum siding business and committed to a plan to settle the related liabilities and realize the related assets through the sale of scrap. Our aluminum siding
operations ceased on June 30, 2006, and all of the employees from our aluminum siding business were transferred to our solar module business. We had net gains from our aluminum siding business of $354,237 and $91,010 in 2004 and 2005,
respectively, and a net loss of $753,277 in 2006. In accordance with Financial Accounting Standards, or FAS, No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, the financial position and results of operations from our
aluminum siding business are reflected as discontinued operations in our consolidated financial statements included elsewhere in this annual report. In December 2006, we entered into a contract to sell the manufacturing equipment and buildings with
the underlying land use rights, previously used in our aluminum siding business, for a total price of RMB5.8 million ($742,761) to Mr. Weifeng Wu and Mr. Weizhong Wu, brothers-in-law of Mr. Jifan Gao, our chairman and chief

executive officer. The price was determined based on the higher of two formal offers, one of which came from a third party unrelated to us, and was approved
by our audit committee and all of our independent directors.

Taxation

We recognize deferred tax assets and liabilities for temporary differences between financial statement and income tax bases of assets and liabilities. Valuation allowances are provided against deferred tax assets when
management cannot conclude that it is more likely than not that some portion or all of the deferred tax asset will be realized.

Under
current PRC laws and regulations, a foreign invested enterprise in China is typically subject to an enterprise income tax of 30% and a local income tax of 3%. In 2002, Trina China relocated to a high-tech zone in Changzhou and was qualified as a
high and new technology enterprise. As a result, it was entitled to a preferential enterprise income tax rate of 15%. In addition, as a foreign invested enterprise engaged in a manufacturing business, Trina China was entitled to a
two-year exemption from the enterprise income tax for its first two profitable years of operation, which were 1999 and 2000, and to a 50% reduction of its applicable income tax rate for the succeeding three years, which were from 2001 to 2003.
Therefore, Trina China had a tax rate of 7.5% in 2003.

In 2004, Trina China moved out of the high-tech zone and was no longer qualified
for a preferential enterprise income tax rate of 15%. Trina China, as a foreign invested enterprise engaged in a manufacturing business and established in Changzhou, which is located within a costal economic zone, is entitled to a preferential
enterprise income tax rate of 24%. Furthermore, the PRC government provides various incentives to foreign invested enterprises which qualify as advanced technological enterprises. Trina China has been qualified as an advanced
technological enterprise and enjoyed a preferential enterprise income tax rate of 12% for the years 2004 to 2006. The PRC has enacted a new tax law to be effective in January 2008 that may change the tax treatment of Trina and Trina China. See
Item 4. Information on the CompanyRegulationTax.

Critical Accounting Policies

We prepare financial statements in accordance with U.S. GAAP, which requires us to make judgments, estimates and assumptions that affect (i) the
reported amounts of our assets and liabilities, (ii) the disclosure of our contingent assets and liabilities at the end of each fiscal period and (iii) the reported amounts of revenues and expenses during each fiscal period. We continually
evaluate these estimates based on our own historical experience, knowledge and assessment of current business and other conditions, our expectations regarding the future based on available information and reasonable assumptions, which together form
our basis for making judgments about matters that are not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, our actual results could differ from those estimates. Some of our
accounting policies require a higher degree of judgment than others in their application.

When reviewing our financial statements, you
should consider (i) our selection of critical accounting policies, (ii) the judgment and other uncertainties affecting the application of such policies and (iii) the sensitivity of reported results to changes in conditions and
assumptions. We believe the following accounting policies involve the most significant judgment and estimates used in the preparation of our financial statements.

Revenue Recognition

We recognize revenues for product sales when persuasive evidence of an arrangement exists, delivery of the product has occurred and title and risk of loss
has transferred to the customer, the sales price is fixed or determinable, and the collectibility of the resulting receivable is reasonably assured. Our sales agreements typically contain our customary product warranties but do not contain any
post-shipment obligations nor any return or credit provisions. We recognize sales of our solar modules based on the terms of the specific sales contract. Generally, we recognize sales when we have delivered our products to our customers
designated point of shipment, which may include commercial docks or commercial shipping vessels. Some of our contracts may stipulate that we must defer recognizing revenues until we have delivered the product to our customers location and we
receive documentation that they have accepted delivery. Revenues also include reimbursements of shipping and handling costs of products sold to customers.

Most of our sales contracts require our customers to make a prepayment depending on the credit status of our customers, market demand and the term of the contracts, with the remaining balance to be paid within 30 days
after shipment. We record these prepayments as advances from customers until revenues are recognized. Our customers generally pay within 30 days after they receive a proof of shipment from us.

We also generate revenues from our solar power system integration business. We recognize revenues on a per project basis and based on the percentage of
completion of the project at the time of determination. The percentage of completion is based on the cost incurred over the total cost budgeted for the project. If we determine that the estimated total cost of completion to be incurred on a project
exceeds the amount of revenues under the contract, we expense that portion of excess cost in the period that we make such determination.

Warranty Cost

It is customary in our business and industry to warrant or guarantee the performance of our solar
module products at certain levels of power output for extended periods. Our solar modules are typically sold with a two-year warranty for defects in material and workmanship and a minimum power output warranty of up to 25 years following the date of
purchase or installation. If a solar module is defective, we will either repair or replace the module at our discretion. We maintain warranty reserves (recorded as accrued warranty costs) to cover potential liability that could arise from our
warranties. Our accrued warranty cost reflects our best estimate of such liabilities. Due to our limited warranty claims to date, we accrue the estimated costs of warranties based on an assessment of our competitors and average industry level. The
provision of the warranty accrues at the time of sale and is recognized as a component of selling expenses. Actual warranty costs are accumulated and charged against the accrued warranty liability. To the extent that actual warranty costs differ
from the estimates, we will prospectively revise our accrual rate.

Impairment of Long-lived Assets and Definite-lived Intangibles

We evaluate our long-lived assets and definite-lived intangibles for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. When these events occur, we measure impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from

the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, we
will recognize an impairment loss based on the fair value of the assets.

Allowance for Doubtful Accounts

We conduct credit evaluations of customers and generally do not require collateral or other security from them. We establish an allowance for doubtful
accounts primarily based upon the age of the receivables and factors surrounding the credit risk of specific customers. We generally do not require collateral or other security interests from our customers when we grant them credit. With respect to
advances to suppliers, our suppliers are primarily suppliers of silicon raw materials. We perform ongoing credit evaluations of our suppliers financial conditions. We generally do not require collateral or security against advances to
suppliers. However, we maintain a reserve for potential credit losses and such losses have historically been within our expectations.

Share-based Compensation

Determining the value of our share based compensation expense in future periods requires
the input of highly subjective assumptions, including estimated forfeitures and the price volatility of the underlying shares. We grant our restricted shares at their fair value which generally represents the fair value of an unrestricted share less
a discount calculated based on the length of time the share is restricted. We estimate our forfeitures based on past employee retention rates, our expectations of future retention rates, and we will prospectively revise our forfeiture rates based on
actual history. Our restricted share compensation charges may change based on changes to our actual forfeitures. See Overview of Financial ResultsShare-based Compensation Expenses.

Inventories

Inventories are
stated at the lower of cost or market. Cost is determined by the weighted average method. Cost comprises direct materials and where applicable, direct labor costs, toll manufacturing costs and those overheads that have been incurred in bringing the
inventories to their present location and condition.

Adjustments are recorded to write down the cost of obsolete and excess inventory to
the estimated market value based on historical and forecast demand.

Income Taxes

Deferred income taxes are recognized for temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial
statements, net operating loss carry forwards and credits by applying enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in our opinion, it is more likely than not that some portion
or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities. The components of the deferred tax assets and liabilities are individually classified as
current and non-current based on the characteristics of the underlying assets and liabilities.

Year Ended December 31, 2006 Compared to Year Ended December 31, 2005

Net Revenues.Our total net revenues increased by $87.2 million, or 319.8%, from $27.3 million in 2005 to $114.5 million in 2006. Our net
revenues increased due to an increase in the volume of the solar modules we sold. The volume of the solar modules we sold increased from 6.8 MW in 2005 to 27.4 MW in 2006 due to the expansion of our manufacturing capacity. In addition, our average
selling price decreased from $4.02 per watt in 2005 to $3.98 per watt in 2006 due to slower demand for solar modules in major markets such as Germany.

We did not generate any system integration revenues in 2005 and recorded net revenues of $162,367 in 2006 from our system integration business in Zhejiang.

Cost of Revenues.Our cost of revenues increased by $63.5 million, or 302.4%, from $21.0 million in 2005 to $84.5 million in 2006. Our cost
of revenues increased primarily due to the rapid expansion of our solar module business. The increase in our cost of revenues was also impacted by the rising prices of silicon raw materials due to the industry-wide shortage of polysilicon. Moreover,
we experienced an increase in depreciation costs due to the wafer manufacturing equipment we installed in 2006 as we ramped up our wafer manufacturing

facilities in February 2006. Cost of revenues in 2006 also included charges of $2.2 million resulting from shipments by suppliers of defective raw materials
to us. These suppliers refused to accept the return of the defective materials or to reimburse us for the amount we had prepaid. These suppliers are not our related parties. We have not made any other prepayment to these suppliers, and we do not
intend to use these suppliers until these disputes have been settled. Any future use of these suppliers will be subject to modified contracts or credit terms. Cost of revenues in 2006 also included $414,941 of share-based compensation expenses. As a
percentage of our total net revenues, our cost of revenues decreased from 76.9% to 73.8% during the same periods. The decrease was primarily due to cost savings derived from the vertical integration of the ingot-to-wafer manufacturing process which
significantly reduced our expenditures on ingots and wafers from third-party suppliers. Our cost of revenues as a percentage of total net revenues decreased also due to the economies of scale we have achieved as our solar module business has grown.

We did not incur any cost of revenues attributable to our system integration business in 2005 and recorded cost of revenues of $158,090 in
2006 attributable to our system integration business in Zhejiang.

Gross Profit.As a result of the foregoing, our gross profit
in 2006 increased by $23.7 million to $30.0 million, from $6.3 million in 2005. Our gross margin increased from 23.1% to 26.2% during the same periods.

Operating Expenses.Our operating expenses increased by $11.1 million, from $2.0 million in 2005 to $13.1 million in 2006. The increase in operating expenses was due to increases in selling expenses,
general and administrative expenses and research and development expenses. As a percentage of total net revenues, operating expenses increased from 7.4% in 2005 to 11.5% in 2006.

Share-based compensation expenses allocated to our selling expenses, general and administrative expenses and research and development expenses in 2006
were $323,003, $389,431 and $1.6 million, respectively, based on the department where such employees worked at the time of the grant. In March 2006, we transferred beneficial interests in our company by our chairman and his wife to certain employees
through the transfer of a 29% ownership interest in Perseverance International Investment Limited, or Perseverance, through which Ms. Chunyan Wu, the wife of our chairman, holds shares of our company, as well as grants of restricted shares to
our employees. Perseverance was established as a British Virgin Islands company by Ms. Wu, as a special purpose vehicle solely for the purpose of holding a portion of the ordinary shares of our company upon restructuring. The special purpose
vehicle Perseverance was used as one of the several options that Mr. Jifan Gao and Ms. Chunyan Wu considered when planning the transfer of interests in our company to certain employees. Ultimately, they considered using Perseverance for
such purpose due in part to a desire to avoid diluting other shareholders beneficial interests in our company. The Perseverance shares were granted for free, and we recorded a share-based compensation expense equal to the fair value of our
ordinary shares on the grant date. Due to a restructuring of Perseverance in May 2007, Ms. Chunyan Wu no longer holds shares in Perseverance. In addition, we adopted our 2006 share incentive plan in July 2006 and granted a total of 45,725,760
restricted shares in July and August 2006. We recorded share-based compensation expenses of $413,679 of our operating expenses in connection with the grants of the restricted shares.

Selling Expenses. Our selling expenses increased by $2.1 million from $520,736 in

solar modules, as well as share-based compensation expenses. Other selling expenses increased due to costs associated with growing our solar module business. Selling expenses as a percentage of net revenues also increased from 1.9% to 2.2%.

General and Administrative Expenses. Our general and administrative expenses increased by $7.3 million, from $1.4 million in 2005 to
$8.7 million in 2006. The increase was due in part to charges of a total amount of $2.2 million that were made in 2006 resulting from failures of three of our suppliers to deliver goods as specified in the contracts and to reimburse us for our
advance payment due to such suppliers own financial difficulties. These suppliers are not related parties to us. We have not made any other prepayments to the suppliers, and we do not intend to use these suppliers until these disputes have
been settled. Any future use of the suppliers will be subject to modified contracts or credit terms. We do not expect similar charges to be a regular occurrence in our ongoing operations. Other than the $2.2 million charges and the $2.2 million
charges related to the suppliers who refused to accept the return, we have not recorded any additional valuation allowance against our advances to supplier balance of $34.6 million as of December 31, 2006. The increase in general and
administrative expenses was also partially attributable to share-based compensation expenses, as well as accruals of audit and legal fees and bonuses to employees. Other general and administrative expenses increased due to the expansion of our solar
module business.

Research and Development Expenses.Research and development expenses increased from $121,594 to $1.9 million
between 2005 and 2006, primarily due to the incurrence of share-based compensation expenses.

Interest Expenses.Our interest
expenses increased by $1.7 million, from $470,245 in 2005 to $2.1 million in 2006. Our interest expenses increased due to increases in interest payments in connection with two long-term loans which we entered into in June and July 2005,
respectively, as well as increases in our short-term borrowings.

Income Tax Expenses.Our income tax expenses
increased by $1.2 million, from $570,723 in 2005 to $1.8 million in 2006. Our income tax expenses increased primarily due to a significant increase in our profitability between 2005 and 2006. Trina China is subject to a preferential income tax rate
of 12% in 2006.

Net Income from Continuing Operations.Net income from our continuing operations increased significantly
between 2005 and 2006, from $3.2 million to $13.2 million. Net margin from our continuing operations decreased from 11.8% to 11.5% over the same periods due to share-based compensation expenses recorded in 2006.

Net Income from Discontinued Operations. We had a net gain of $91,010 and a net loss of $753,277 from our discontinued aluminum sidings
business in 2005 and 2006, respectively, as we wound down such business.

Net Income.As a result of the foregoing, our net
income increased significantly, from $3.3 million in 2005 to $12.4 million in 2006, representing an increase of $9.1 million. Our net margin decreased from 12.1% to 10.8% over the same periods partially due to share-based compensation expenses
recorded in 2006.

Year Ended December 31, 2005 Compared to Year Ended December 31, 2004

Net Revenues. Our total net revenues increased by $26.9 million, or 6,494%, from $413,632 in 2004 to $27.3 million in 2005. The increase
was due to the significant increase in revenues in our solar module business, which completed its first full year of operations. The volume of the solar modules we sold significantly increased from 0.12 MW in 2004 to 6.79 MW in 2005. The average
selling price of our solar modules rose from $3.45 per watt in 2004 to $4.02 per watt in 2005 due to industry-wide higher prices for solar modules.

We did not generate any system integration revenues in 2004 and 2005.

Cost of Revenues. Our cost of revenues
increased by $20.6 million, or 5,526%, from $373,028 in 2004 to $21.0 million in 2005. Our cost of revenues was driven by the rising prices of silicon raw materials due to the industry-wide shortage of polysilicon and high demand for such materials.
We also experienced an increase in depreciation of equipment due to the installation of our ingot manufacturing capacities in July 2005. As a percentage of our total net revenues, cost of revenues decreased from 90.2% in 2004 to 76.9% in 2005. The
decrease in our cost of revenues as a percentage of our total revenues was due primarily to the rapid increase in our net revenues in the first full year of our solar module operations, offset in part by an increase in our expenditures on silicon
raw materials and other direct costs.

We did not incur any cost of revenues in 2004 and 2005 attributable to our system integration
business.

Gross Profit. As a result of the foregoing, our gross profit increased by $6.2 million, or 15,390%, from $40,604 in
2004 to $6.3 million in 2005. Our gross margin increased from 9.8% in 2004 to 23.1% in 2005.

Operating Expenses. Our operating
expenses increased by $1.6 million, or 448%, from $368,287 in 2004 to $2.0 million in 2005. The increase in our operating expenses was due to increases in selling expenses and general and administrative expenses, offset by a decrease in research and
development costs. Operating expenses as a percentage of our total net revenues decreased from 89.0% in 2004 to 7.4% in 2005.

Selling
Expenses. Our selling expenses increased by $452,522, or 686.4%, from $66,214 in 2004 to $520,736 in 2005. The increase in our selling expenses was due primarily to provision for warranty for solar modules that was established in 2005. Selling
expenses as a percentage of our net revenues decreased from 16.0% in 2004 to 1.9% in 2005. Selling expenses as a percentage of net revenues decreased primarily due to our achieving economies of scale in our operations.

General and Administrative Expenses. Our general and administrative expenses increased by $1.3 million, or 3,367%, from $39,650 in 2004 to $1.4
million in 2005. The increase in our general and administrative expenses was due primarily to increases in salaries and benefits for our administrative and finance personnel as we hired additional personnel in connection with our expansion into
solar module business. General and administrative expenses as a percentage of our total net revenues decreased from 9.6% in 2004 to 5.0% in 2005 primarily due to our achieving economies of scale in our operations.

Research and Development Expenses. Our research and development expenses

decreased by $140,829, or 53.7%, from $262,423 in 2004 to $121,594 in 2005. At the end of 2004 we sold our research and development subsidiary, Tianhe
Research Institute, and in 2005 we received an annual research grant from the PRC government that exceeded the amount we received in 2004. Both of these events contributed to decreases in research and development expenses between 2004 and 2005.

Interest Expenses. Our interest expense increased by $397,631, or 547.6%, from $72,614 in 2004 to $470,245 in 2005 due to
increases in interest payments in connection with our two long-term loans which we entered into in 2005, as well as increases in our short-term borrowings.

Income Tax Expenses. Our income tax expenses increased by $622,530, from an income tax benefit of $51,807 in 2004 to an income tax expense of $570,723 in 2005. The income tax benefit in 2004 was primarily
due to a loss in our income before income tax in 2004, which partly offset the taxable income from our discontinued operations. In 2005, we had a taxable income from our continuing operations of $3.8 million. Trina China was subject to preferential
enterprise income tax rates of 12% in 2004 and 2005.

Net Income from Continuing Operations. Net income from our continuing
operations increased significantly by $3.6 million, from a loss of $366,647 in 2004 to $3.2 million in 2005. The net margin of our continuing operations increased from a negative 88.6% to 11.8% over the same periods.

Net Income from Discontinued Operations. The gain from our discontinued aluminum operations decreased by $263,227 from $354,237 in 2004 to
$91,010 in 2005 as we wound down such business.

Net Income. As a result of the foregoing, our net income increased
significantly by $3.3 million, from a loss of $12,410 in 2004 to $3.3 million in 2005. Our net margin increased from a negative 3.0% to 12.1% over the same periods.



|B. | Liquidity and Capital Resources
|-- | -------------------------------

Cash Flows and Working
Capital

We have financed our operations primarily through short-term borrowings, term loans and equity contributions by our
shareholders and, to a lesser extent, cash generated from operations. As of December 31, 2004, 2005 and 2006, we had $3.4 million, $1.2 million and $93.4 million, respectively, in cash and cash equivalents and $3.7 million, $11.6 million and
$76.5 million, respectively, in outstanding borrowings, of which $3.7 million, $6.6 million and $71.4 million, respectively, were due within one year. Our cash and cash equivalents primarily consist of cash on hand and demand deposits with original
maturities of three months or less that are placed with banks and other financial institutions. Our short-term borrowings outstanding as of December 31, 2004, 2005 and 2006 bore an average interest rate of 5.91%, 6.10% and 6.10%, respectively.
In connection with our short-term borrowings, we have granted security interests over significant amounts of our assets. For example, in September 2006, we pledged our raw materials and inventories of a total appraised value of RMB144.31 million
($18.49 million) to secure repayment of our short-term borrowings of RMB70.0 million ($8.97 million) that will become due in September and October 2007. In March 2007, we mortgaged 20,381 square meters of our facilities and the underlying land use
rights of 51,746 square meters to secure repayment of our RMB34.0 million ($4.36 million) short-term borrowings that will become due on

March 30, 2008. We did not have any outstanding long-term borrowings as of December 31, 2004, and had $5.0 million and $5.1 million of long-term
borrowings as of December 31, 2005 and 2006, respectively, from two term loans. These term loans have three-year terms expiring on June 20, 2008 and July 7, 2008, respectively, and are guaranteed by Changzhou Fulai Property
Development Co., Ltd., a related party. Each of the term loans bears an interest rate of 6.91% per annum. We have historically been able to repay our total borrowings as they became due mostly from capital contributions from our shareholders
and proceeds from short-term and long-term borrowings. We may also seek additional debt or equity financing to repay the remaining portion of our borrowings. As we continue to ramp up our current and planned operations in order to complete our
vertical integration and expansion strategies, we also expect to generate cash from our expanded operations to repay a portion of our borrowings.

We have significant working capital commitments because suppliers of polysilicon and reclaimable silicon raw materials require us to make prepayments in advance of shipment. Due to the industry-wide shortage of polysilicon, working capital
and access to financings to allow for the purchase of silicon raw materials are critical to growing our business. Our short-term borrowings increased primarily as a result of our need to fund our expanded working capital, including advances to
supplier and increase in our inventory. Our advances to suppliers increased significantly from $426,669 as of December 31, 2004 to $34.6 million as of December 31, 2006 due to the significant growth of our solar module business.

We expect that our accounts receivable and inventories, two of the principal components of our current assets, will continue to increase
as our net revenues increase. Although we require prepayments (depending on the credit status of our customers, market demand and the term of the contracts), we also allow some of our customers to pay a major portion of the purchase price by letters
of credit. Until the letters of credit are drawn in accordance with their terms, the amount earned is recorded as accounts receivable. Because of the prepayment and the letters of credit payment requirements that we impose on our customers, our
allowance for doubtful accounts has not been significant with respect to our solar module business.

The following table sets forth a
summary of our cash flows for the periods indicated:

Net cash used in operating activities amounted to $54.0 million in 2006, mainly as a result of a
significant increase in advances to suppliers and inventories primarily due to increases in volumes of silicon raw materials purchased, partially offset by a positive net income and an increase in accounts payable. Net cash used in operating
activities in 2005 was $8.0 million, compared to $1.9 million in 2004. The net cash used in operating activities in 2005 was mainly a result of significant increases in accounts receivable, other receivables and inventories primarily due to
increases in prices and volumes of silicon raw materials

purchased. The net cash used in operating activities in 2005 was partially offset by a positive net income and an increase in accounts payable in 2005. In
2004, net cash used in operating activities was mainly a result of increases in inventories and accounts receivable due to growth in our solar module operations and amounts due from related parties.

Net cash used in investing activities amounted to $46.6 million in 2006, primarily as a result of an increase in property, plant and equipment
expenditures, comprised mainly of purchases of wafer sawing machines related to the beginning of our production of silicon wafers in February 2006, and the continuing expansion of our other manufacturing facilities. Net cash used in investing
activities in 2006 also included an increase in restricted cash, which includes cash pledged to banks to secure our notes payable and letter of credit facilities. Net cash used in investing activities increased from $1.5 million in 2004 to $8.3
million in 2005, primarily as a result of an increase in property, plant and equipment expenditures in 2005 comprised mainly of purchases of ingot pulling machines related to the beginning of our production of silicon ingots in August 2005 and the
expansion of our assembly lines for the production of solar modules. In 2004, net cash used in investing activities was comprised of property, plant and equipment expenditures for our solar module assembly lines and the acquisition of land use
rights.

Net cash provided by financing activities amounted to $191.0 million in 2006, which consisted primarily of net proceeds received
from our initial public offering. Net cash provided by financing activities amounted to $13.9 million in 2005, consisting of proceeds received from short-term and long-term borrowings and subscriptions for our shares. Net cash provided by financing
activities was $6.1 million in 2004, consisting of proceeds from short-term borrowings and subscriptions for our shares.

We believe that
our current cash and cash equivalents, anticipated cash flow from operations and proceeds from our initial public offering will be sufficient to meet our anticipated cash needs, including our cash needs for working capital and capital expenditures
for the next 12 months. We may, however, require additional cash due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our existing cash is insufficient to meet our
requirements, we may seek to sell additional equity securities, debt securities or borrow from lending institutions. We cannot assure you that financing will be available in the amounts we need or on terms acceptable to us, if at all. The sale of
additional equity securities, including convertible debt securities, would dilute our earnings per share. The incurrence of debt would divert cash for working capital and capital expenditures to service debt obligations and could result in operating
and financial covenants that restrict our operations and our ability to pay dividends to our shareholders.

Capital Expenditures

We had capital expenditures of $676,166, $7.7 million and $41.4 million in 2004, 2005 and 2006, respectively. Our capital expenditures were used
primarily to purchase equipment for the production of ingots, wafers, cells and modules. We estimate that our capital expenditure in 2007 will be used primarily to build our own solar cell plant and purchase equipment for the expansion of our
manufacturing and assembly lines. We expect our total capital expenditures to be approximately $100 million in 2007. We plan to increase our annual manufacturing capacity from ingots to solar modules to 150 MW by the end of 2007. We expect our total
expenditures to be approximately $200 million in 2008. We plan to increase our annual manufacturing capacity from ingots to solar modules to 350 MW by the end of 2008.

|C. | Research and Development
|-- | ------------------------

We focus our research and
development efforts towards improving our ingot, wafer, solar cell and solar module manufacturing capabilities. We seek to reduce manufacturing costs and improve the performance of our products. As of December 31, 2006, our research and
development staff consisted of 38 employees. In addition, some of our manufacturing employees regularly participate in our research and development programs.

Our research and development department is divided into teams responsible for research of each stage of the solar power value chain, such as ingot, wafer, solar cell and solar module production and system integration.
We also have a technology committee, which meets regularly to review current development progress and identify new research and development areas. Our technology committee is spearheaded by our senior management and is comprised of both our
employees and external solar energy experts.

Our research efforts are currently focused on our four main product areas, namely ingots,
wafers, solar cells and solar modules. We seek to increase the size of the ingots we produce and to use a higher proportion of reclaimable silicon raw materials in the production of ingots. We are working towards the production, on a trial basis, of
silicon wafers with a width of 156 millimeters, from 125 millimeters currently, sliced from larger ingots. We are exploring ways to reduce the thickness of such wafers to a 200 micron thickness from the current 220 micron thickness. For the assembly
of modules, our research and development team works closely with our manufacturing team and customers to improve our solar module and system designs, including integrating construction elements with our modules for use in system integration projects
that require our modules to be built for certain applications, such as roof tiles and glass panels. We hope to increase the power output of our solar modules to 230 MW by 2008, as well as to reduce the number of solar cells within a module.

As we expand into solar cell manufacturing, we are developing the process technology to make full use of the conversion efficiency
advantages of monocrystalline silicon over other solar power technologies, while simultaneously reducing the manufacturing costs. We have achieved an average conversion efficiency of 16.3% and plan to increase the efficiency to 17.2% by the end of
2008. We have a team of ten employees dedicated to the development and implementation of this process technology. In December 2006, we entered into an arrangement with Q-Cells AG pursuant to which Q-Cells AG has agreed to provide technical
assistance to us during the ramp-up phase of our solar cell production lines. We also plan to make additional efforts to realize the technical and cost synergies of having in-house vertically integrated manufacturing capabilities.

In each of the three years ended December 31, 2004, 2005 and 2006, our research and development expenditures were $262,423, $121,594 and $1.9
million, representing 63.4%, 0.4% and 1.7% of our total revenues for 2004, 2005 and 2006, respectively.

No executive officer is entitled to any severance benefits

2006 Share Incentive Plan

In July 2006, our board of directors adopted a 2006 share incentive plan to link the personal interests of our board members, employees and consultants to
those of our shareholders by providing them with an incentive to generate superior returns for our shareholders, as well as to provide us with the flexibility to motivate, attract and retain the services of these individuals upon whose judgment,
interest and special effort the successful conduct of our operations is dependent. We have reserved 52,631,579 shares for issuance under our 2006 share incentive plan. The following paragraphs describe the principal terms of our 2006 share incentive
plan.

Administration. Our 2006 share incentive plan is administered by our compensation committee or, in its absence, by our
board of directors. Our compensation committee will determine the provisions, terms and conditions of our awards, including, but not limited to, vesting schedule, repurchase provisions, forfeiture provisions, form of payment upon settlement of the
award, payment contingencies and satisfaction of any performance criteria. The compensation committee may delegate to a committee of one or more members of our board of directors the authority to make grants or amend prior awards to employees,
consultants and directors.

Awards.The following briefly describe the principal features of the various awards that may be
granted under our 2006 share incentive plan.



| |  |  | Options. Options provide for the right to purchase our ordinary shares at a specified price, and usually will become exercisable in the discretion of our
compensation committee in one or more installments after the grant date. The option exercise price may be paid in cash, by check, our ordinary shares which have been held by the option holder for such time as may be required to avoid adverse
accounting treatment, other property with value equal to the exercise price, through a broker assisted cash-less exercise or such other methods as our compensation committee may approve from time to time.

Termination of Plan. Unless terminated earlier, our 2006 share incentive plan will expire in
2016. Our board of directors has the authority to amend or terminate our share incentive plan subject to shareholder approval to the extent necessary to comply with applicable law. However, no such action may impair the rights of any recipient of
the awards unless agreed by the recipient and the share incentive plan administrator.

Restricted Shares

As of the date of this annual report, our board of directors has granted certain of our officers, employees and consultants an aggregate of 50,846,754
restricted shares in our company. The following paragraphs describe the principal terms of our restricted shares.

Restricted Share
Award Agreement. Restricted shares issued under our 2006 share incentive plan will be evidenced by a restricted share award agreement that contains, among other things, provisions concerning the purchase price for the shares, if any,
vesting and repurchase by us upon termination of employment or consulting arrangement, as determined by our compensation committee.

Vesting Schedule. In general, provided the holder remains an employee, director or consultant, as the case may be, twenty percent (20%) of the restricted shares issued under our 2006 share incentive plan shall vest on the
first anniversary following the award grant. The remaining eighty percent (80%) will vest ratably in twenty percent (20%) increments on the second, third, fourth and fifth anniversaries of the award grant date. Restricted shares also fully
vest upon termination of service due to death or disability.

Transfer Restrictions. Until vested, the restricted shares are
not transferable and may not be sold, pledged or otherwise transferred.

Dividend and Voting Rights. The restricted shares will
not be entitled to dividends paid on the ordinary shares until such restricted shares are vested. A holder will not be entitled to vote restricted shares until such restricted shares are vested.

Repurchase of Restricted Shares. Following the holders termination of service with us, except if such termination is a result of death
or disability, the restricted shares that are unvested will be repurchased by us for an amount equal to the price paid, if anything, for such shares. Such repurchase must be accomplished within 180 days after the termination of service.

Third-Party Acquisition. If a third party acquires us through the purchase of all or substantially all of our assets, a merger or other
business combination, all outstanding awards will be assumed or equivalent awards substituted by the successor corporation or parent or subsidiary of successor corporation. In the event that the successor corporation refuses to assume or substitute
for awards, all awards will become fully vested and exercisable immediately so long as the recipient remains an employee, consultant or director on the effective date of the acquisition.

|-- | ---------------

Board of Directors

Our board of directors consists of seven directors. Our directors are elected by the holders of our ordinary shares. At each annual general meeting,
one-third of our directors are subject to re-election. The directors to retire by rotation shall include (so far as necessary to ascertain the number of directors to retire by rotation) any director who wishes to retire and does not offer himself
for re-election. Any other directors to retire will be those of the other directors who are longest in office since their last re-election or appointment, or by lot should they be of the same seniority. Our directors have the power to appoint a
director to fill a vacancy on our board or as an addition to the existing board. Any director so appointed shall hold office only until the next following annual general meeting and shall then be eligible for re-election. In May 2007,
Mr. Canfang Liu retired from our board and Mr. Qian Zhao was appointed as a director by our directors. On the basis of the foregoing, Mr. Jifan Gao and Mr. Jianwei Shi are of the same seniority, and they and Mr. Qian Zhao
shall be subject to re-election in the first annual general meeting following our initial public offering. Mr. Liping Qiu and Dr. Sven M. Hansen shall be subject to re-election in the second annual general meeting following our
initial public offering. The remaining independent director shall be subject to re-election in the third annual general meeting following our initial public offering. A director is not required to hold any shares in our company by way of
qualification. A director may vote with respect to any contract, proposed contract or arrangement in which he is materially interested. A director may exercise all the powers of the company to borrow money, mortgage its undertakings, property and
uncalled capital, and issue debentures or other securities whenever money is borrowed or pledged as security for any obligation of our company or of any third party.

Duties of Directors

Under Cayman Islands law, our directors have a statutory duty of loyalty to act honestly in good faith with a view to our best interests. Our directors also have a duty to exercise the skill they actually possess with
the care and diligence that a reasonably prudent person would exercise in comparable circumstances. In fulfilling their duty of care to us, our directors must ensure compliance with our memorandum and articles of association. A shareholder has the
right to seek damages if a duty owed by our directors is breached.

Terms of Directors and Officers

A director may be removed by ordinary resolution passed by our shareholders before the expiration of such directors term. Officers are elected by
and serve at the discretion of the board of directors.

Employment Agreements

We have entered into employment agreements with each of our executive officers. Under these agreements, each of our executive officers is employed for a
specified time period. We may terminate the employment for cause, at any time, without notice or remuneration, for certain acts of the employee, including but not limited to a conviction or plea of guilty to a felony, negligence or dishonesty to our
detriment and failure to perform the agreed-to duties after a reasonable opportunity to cure the failure. An executive officer may terminate his employment at any time without notice or penalty if there is a material reduction in his authority,
duties and responsibilities or if there is a material reduction in his annual salary before the next annual salary review. Furthermore, either party may terminate the employment at any time without cause upon advance written notice to the other
party. If we terminate the executive officers employment without cause, the executive officer will be entitled to a severance payment equal to a certain specified number of months of his or her then base salary, depending on the length of his
or her employment with us.

Each executive officer has agreed to hold, both during and after the employment agreement expires or is earlier
terminated, in strict confidence and not to use, except as required in the performance of his duties in connection with the employment, any confidential information, technical data, trade secrets and know-how of our company or the confidential
information of any third party, including our affiliated entities and our subsidiaries, received by us. The executive officers have also agreed to disclose in confidence to us all inventions, designs and trade secrets which they conceive, develop or
reduce to practice and to assign all right, title and interest in them to us.

Restructuring

In connection with the establishment of Trina in March 2006, Trina issued 10,000 ordinary shares at par value $1.00 per share to the following entities,
which are the nominees of shareholders of Trina China, based on such shareholders proportionate ownership in Trina China:



|                                              |  |                                                                                                         |  |

In April 2006, these 10,000 ordinary shares with par value of $1.00 each were sub-divided into 1
billion ordinary shares with par value of $0.00001 each. In May 2006, Trina issued 545.8 million Series A preferred shares with par value of $0.00001 each for cash proceeds of approximately $40.0 million. Trina then used $5.1 million out of the
proceeds to purchase all of the outstanding equity interests in Trina China from the shareholders of Trina China as follows;

Tianhe Investment Co., Ltd. and Changzhou Wujin Nanfang Bearing Co., Ltd.,

were paid not less than their investment cost in Trina China. Such amount was then contributed back to Trina China by these PRC shareholders as cash advances
to finance Trina Chinas operations. We repaid RMB40.7 million ($5.1 million) to the former PRC shareholders in October 2006. In October and November 2006, these shareholders remitted to us as gift an aggregate of $4.9 million. As a result,
Trina will effectively have paid nominal consideration to all transferors, including both former foreign and PRC shareholders for all equity interests in Trina China.

The foreign shareholders of Trina China have provided us with an indemnity against any withholding obligations and liabilities due to or imposed by the PRC tax authorities that may arise out of the restructuring.

Please see Item 3. Key InformationD. Risk FactorsRisks Related to Our Company and Our IndustryTrina or Trina China
may be required by the PRC tax authorities to withhold capital gains tax arising out of our restructuring in May 2006. for more details.

The effect of these transactions was that, post-restructuring and prior to our initial public offering, Trina Chinas former shareholders held a proportionate share of Trinas ordinary shares based on their prior proportionate
equity interests in Trina China excluding Trinas Series A preferred shareholdings. Trina China became a wholly-owned subsidiary of Trina.

Issuance and Sale of Series A Preferred Shares

In May 2006, we sold a total of 545,808,968 Series A preferred shares in a
private placement at a price of $0.0732857 per share for an aggregate of approximately $40 million. The investors in our Series A preferred share private placement consisted of Milestone Solar Holdings I Limited, which purchased 136,452,242 shares,
Milestone Solar Holdings II Limited, which purchased 13,645,225 shares, VDCI S.A., which purchased 20,467,836 shares, IPROP Holdings Limited, which purchased 20,467,836 shares, Triumph Sky Technology Limited, which purchased 68,226,121 shares,
Accurate Group Holdings Limited, which purchased 13,645,224 shares, Indopark Holdings Limited, which purchased 136,452,242 shares, and Good Energies Investments Limited, which purchased 136,452,242 shares. We used the proceeds from the Series A
private placement primarily to fund capital investment for the expansion of our facilities in Changzhou.

Each of the Series A preferred
shares was converted into one ordinary share upon completion of our initial public offering. Holders of ordinary shares issued upon conversion of our Series A preferred shares are entitled to certain registration rights, including demand
registration, piggyback registration and Form F-3 or Form S-3 registration.

Loans and guarantees

In June
and July 2005, we entered into two long-term loans with Bank of Communications. These loans have been guaranteed by Changzhou Fulai Property Development Co., Ltd., a related party controlled by Mr. Canfang Liu and Mr. Lai Shing Yip, two of
our beneficial shareholders. As of date of this annual report, an aggregate of $5.1 million of the long-term loans were outstanding.

We
have also entered into short-term loans with domestic banks, some of which are guaranteed by related parties. As of December 31, 2006, an aggregate of RMB250.0 million ($32.0 million) of the short-term loans guaranteed by related parties were

| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, we have also entered into the following guarantee arrangements:

| |  |  | In February 2006, Changzhou Fulai Property Development Co., Ltd. entered into an agreement with Bank of Agriculture and us to guarantee up to RMB64.0 million ($8.2
million) for our short-term borrowings that will expire by February 2008.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Some of short-term loans are guaranteed by
unrelated parties. A guarantee by an unrelated party is in turn guaranteed by related parties in an arrangement called counter-guarantee. In December 2005, Changzhou City Hengtai Investment Guarantee Co., Ltd., an unrelated party, agreed
to provide a guarantee up to RMB27.0 million ($3.5 million) for our short-term borrowings that will expire by December 2007. Changzhou Tianhe Investment Co., Ltd. provided counter-guarantee against the guarantee, and Mr. Jifan Gao and
Ms. Chunyan Wu also jointly and severally provided a counter-guarantee against the guarantee. Trina China granted a security interest in its property and equipment to the provider of the guarantee. In May 2006, Changzhou Hengtai Investment
Guarantee Co., Ltd. provided a guarantee for our short-term borrowings of RMB30.0 million ($3.8 million). In June 2006, Changzhou Hengtai Investment Guarantee Co., Ltd. provided guarantees for our short-term borrowings of RMB50.0 million ($6.4
million) and $10.0 million ($1.3 million), which were fully repaid. In October 2006, Changzhou Hengtai Investment Guarantee Co., Ltd. provided a guarantee for our short-term borrowings of RMB50.0 million ($6.4 million). The
counter-guarantee arrangement terminated in March 2007. Currently, the guarantees provided by Changzhou City Hengtai Investment Guarantee Co., Ltd. are not counter-guaranteed by any related parties.

In 2006, we also obtained short-term financings from Changzhou Fulai Property Development Co., Ltd. and Jiangsu Jiuzhou Investment Group Co., Ltd., a
company controlled by Mr. Canfang Liu. The amounts of such short-term financings were RMB8.0 million ($1.0 million), RMB18.0 million ($2.3 million) and RMB20.0 million ($2.6 million), and the terms ranged from four days to 34 days. Interest was
charged at 7.2% per annum. We recorded a total amount of RMB162,680 ($20,845) in interest expense in the year ended December 31, 2006. These financings were fully repaid prior to December 31, 2006.

Disposal of Tianhe Research

In December 2004, we disposed of our entire equity interest in Tianhe Research, a former subsidiary established to conduct research and development, to Mr. Jiqing Gao, the brother of our chairman and one of our employees, and Changzhou
Tianhe Investment Co., Ltd, a company controlled by our chairman and Mr. Jiqing Gao. The net assets of Tianhe Research at the date of disposal were $160,595 and the consideration for the disposal was $326,225, the registered capital of Tianhe
Research. The purpose of the disposal was to streamline our research and development capabilities. Concurrent with the disposal, Tianhe Research transferred all of its technology relating to solar research and development to Trina China and retained
assets consisting of a building and cash.

Sun Era

In the past, we procured raw materials and made toll manufacturing purchases from certain suppliers through Sun Era Industries Limited, or Sun Era, whose
sole shareholder is Ms. Chunyan Wu, the wife of our chairman. Sun Era was established as a British Virgin Islands company in October 2002 by our chairman Mr. Jifan Gao, and his wife, Ms. Wu, as an offshore special purpose vehicle. It
was subsequently used solely for facilitating our sale and purchase arrangements with our overseas silicon suppliers at the suggestion of our overseas silicon suppliers. It is customary for PRC-based manufacturing companies to establish such
offshore special purpose vehicles to conduct trading activities, such as finding overseas suppliers and buyers and sourcing and shipping products.

##### Table of Contents

Sun Era did not engage in any business until 2005. In 2005, Trina China sold $0.8 million of silicon
ingots and wafers to Sun Era for Sun Era to arrange for further processing under toll manufacturing arrangements with third party suppliers. In 2005 and 2006, Trina China purchased $0.4 million and $0.9 million, respectively, of silicon raw
materials through Sun Era and purchased $0.4 million and nil, respectively, of solar cells pursuant to toll manufacturing arrangements through Sun Era. These sales and purchases were effected through customary agreements or purchase orders between
Trina China and Sun Era. Sun Era has not made any profit from doing business with us. In 2005 and 2006, Sun Era had net losses of $144,518 and $110,584, respectively.

Disposal of Assets Used in Discontinued Operation

Prior to June 30, 2006, we were
engaged in the aluminum siding business, which included the production, marketing and sale of aluminum exterior wall products used for cladding the exteriors of buildings and houses. On June 28, 2006, our board of directors resolved to
discontinue our aluminum siding business and committed to a plan to settle the related liabilities and realize the related assets through the sale of scrap. Our aluminum siding operations ceased on June 30, 2006, and all of the employees from
our aluminum siding business were transferred to our solar module business. In December 2006, we sold the manufacturing equipment and buildings with the underlying land use rights of 7,633 square meters, previously used in our aluminum siding
business, for a total price of RMB5.8 million ($742,761) to Mr. Weifeng Wu and Mr. Weizhong Wu, brothers-in-law of Mr. Jifan Gao, our chairman and chief executive officer.

Legal and Administrative Proceedings

We are currently not a party to any material legal or administrative proceedings, and we are not aware of threatened material legal or administrative

paid in U.S. dollars.



|B. | Significant Changes
|-- | -------------------

In January 2007, we sold an
additional 510,300 ADSs, representing 51,030,000 ordinary shares, pursuant to the underwriters over-allotment option to purchase these additional ADSs from us at the initial public offering price less the underwriting commission. We received
net proceeds of approximately $8.8 million from this over-allotment sale. On June 6, 2007, we completed a follow-on public offering of 5,406,280 ADSs, representing 540,628,000 ordinary shares, sold by us and certain selling shareholders.
As a result, our outstanding share capital increased from 2,121,534,728 ordinary shares as of December 31, 2006 to 2,537,687,322 ordinary shares as of the date of this annual report.

During the follow-on public offering, we have granted to the underwriters an option, which is exercisable within 30 days from May 31, 2007, to

The following summary of the material
Cayman Islands and United States federal income tax consequences of an investment in our ADSs or ordinary shares is based upon laws and relevant interpretations thereof in effect as of the date of this annual report, all of which are subject to
change. This summary does not deal with all possible tax consequences relating to an investment in our ADSs or ordinary shares, such as the tax consequences under state, local and other tax laws.

Cayman Islands Taxation

The Cayman Islands currently
levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the Government
of the Cayman Islands except for stamp duties which may be applicable on

##### Table of Contents

instruments executed in, or brought within the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties. There are no
exchange control regulations or currency restrictions in the Cayman Islands.

United States Federal Income Taxation

The following discussion describes the material United States federal income tax consequences to U.S. Holders (defined below) under present law of the
ADSs or ordinary shares. This summary applies only to U.S. Holders that hold the ADSs or ordinary shares as capital assets and that have the U.S. dollar as their functional currency. This discussion is based on the tax laws of the United States as
in effect on the date of this annual report and on United States Treasury regulations in effect or, in some cases, proposed, as of the date of this annual report, as well as judicial and administrative interpretations thereof available on or before
such date. All of the foregoing authorities are subject to change, which change could apply retroactively and could affect the tax consequences described below.

The following discussion does not deal with the tax consequences to any particular investor or to persons in special tax situations such as:



| |  |  | banks;
| | - |  | ------



| |  |  | financial institutions;
| | - |  | -----------------------



| |  |  | insurance companies;
| | - |  | --------------------



| |  |  | broker dealers;
| | - |  | ---------------



| |  |  | traders that elect to mark to market;
| | - |  | -------------------------------------



| |  |  | tax-exempt entities;
| | - |  | --------------------



| |  |  | persons liable for alternative minimum tax;
| | - |  | -------------------------------------------



| |  |  | persons holding an ADS or ordinary share as part of a straddle, hedging, conversion or integrated transaction;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | persons that actually or constructively own 10% or more of our voting shares;
| | - |  | -----------------------------------------------------------------------------



| |  |  | persons who acquired ADSs or ordinary shares pursuant to the exercise of any employee share option or otherwise as consideration; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | persons holding ADSs or ordinary shares through partnerships or other pass-through entities.
| | - |  | --------------------------------------------------------------------------------------------

U.S. Holders are urged to consult their tax advisors about the application of the United States federal tax rules to their particular circumstances as well as the
state and local and foreign tax consequences to them of the purchase, ownership and disposition of ADSs or ordinary shares.

##### Table of Contents

The discussion below of the United States federal income tax consequences to U.S. Holders
will apply if you are the beneficial owner of ADSs or ordinary shares and you are, for United States federal income tax purposes,



| |  |  | a citizen or individual resident of the United States;
| | - |  | ------------------------------------------------------



| |  |  | a corporation (or other entity taxable as a corporation for United States federal income tax purposes) organized under the laws of the United States, any State or
the District of Columbia;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an estate whose income is subject to United States federal income taxation regardless of its source; or
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | a trust that (1) is subject to the supervision of a court within the United States and the control of one or more United States persons or (2) has a valid
election in effect under applicable United States Treasury regulations to be treated as a United States person.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If you
are a partner in a partnership or other entity taxable as a partnership that holds ADSs or ordinary shares, your tax treatment depends on your status and the activities of the partnership.

The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and
any related agreement will be complied with in accordance with their terms. If you hold ADSs, you will be treated as the holder of the underlying ordinary shares represented by those ADSs for United States federal income tax purposes.
Accordingly, deposits or withdrawals of ordinary shares for ADSs will not be subject to United States federal income tax.

The U.S.
Treasury has expressed concerns that parties to whom ADSs are pre-released may be taking actions that are inconsistent with the claiming, by U.S. Holders of ADSs, of foreign tax credits for United States federal income tax purposes. Such actions
would also be inconsistent with the claiming of the reduced rate of tax applicable to dividends received by certain non-corporate U.S. Holders, as described below. Accordingly, the availability of the reduced tax rate for dividends received by
certain non-corporate U.S. Holders could be affected by future actions that may be taken by the U.S. Treasury or parties to whom ADSs are pre-released.

Taxation of Dividends and Other Distributions on the ADSs or Ordinary Shares

Subject to the passive foreign
investment company rules discussed below, the gross amount of all our distributions to you with respect to the ADSs or ordinary shares generally will be included in your gross income as foreign source dividend income on the date of receipt by the
depositary, in the case of ADSs, or by you, in the case of ordinary shares, but only to the extent that the distribution is paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). The
dividends will not be eligible for the dividends-received deduction allowed to corporations in respect of dividends received from other U.S. corporations.

With respect to non-corporate U.S. Holders including individual U.S. Holders, for taxable years beginning before January 1, 2011, dividends may be taxed at the lower applicable capital gains rate, and thus may
constitute qualified dividend income provided that (1) the ADSs or ordinary shares are readily tradable on an established securities market in the United States, (2) we are not a passive foreign investment company (as discussed
below) for either our taxable year in which the dividend was paid or the preceding taxable



82



---

##### Table of Contents

year, and (3) certain holding period requirements are met. Under Internal Revenue Service authority, common or ordinary shares, or ADSs representing
such shares, are considered for the purpose of clause (1) above to be readily tradable on an established securities market in the United States if they are listed on the New York Stock Exchange, as our ADSs are. You should consult your tax
advisors regarding the availability of the lower rate for dividends paid with respect to our ADSs or ordinary shares. For taxable years beginning after December 31, 2006, dividends paid on our common shares will generally constitute
passive category income but could, in the case of certain U.S. Holders, constitute general category income.

To the
extent, if any, that the amount of any such distribution exceeds our current or accumulated earnings and profits, it will be treated first as a tax-free return of your tax basis in the ADSs or the ordinary shares (thereby increasing the amount of
any gain or decreasing the amount of any loss realized on the subsequent sale or disposition of such ADSs or ordinary shares) and thereafter as capital gain. However, we do not intend to calculate our earnings and profits under U.S. federal income
tax principles. Therefore, a U.S. Holder should expect that a distribution generally will be treated as a dividend even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described
above.

Taxation of Disposition of Shares

Subject to the passive foreign investment company rules discussed below, you will recognize taxable gain or loss on any sale, exchange or other taxable disposition of an ADS or ordinary share equal to the difference
between the amount realized (in U.S. dollars) for the ADS or ordinary share and your tax basis (in U.S. dollars) in the ADS or ordinary share. The gain or loss will be capital gain or loss. If you are a non-corporate U.S. Holder, including an
individual U.S. Holder, who has held the ADS or ordinary share for more than one year, you will be eligible for reduced tax rates. The deductibility of capital losses is subject to limitations. Any such gain or loss that you recognize will be
treated as United States source income or loss (in the case of losses, subject to certain limitations).

Passive Foreign Investment Company

We believe that for our taxable year ending December 31, 2006, we were not a passive foreign investment company, or PFIC, for
United States federal income tax purposes. A non-U.S. corporation is considered a PFIC for any taxable year if either:



| |  |  | at least 75% of its gross income is passive income, or the income test, or
| | - |  | --------------------------------------------------------------------------



| |  |  | at least 50% of the value of its assets (based on an average of the quarterly values of the assets during a taxable year) is attributable to assets that produce or
are held for the production of passive income, or the asset test.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We will be treated as owning our proportionate share
of the assets and earning our proportionate share of the income of any other corporation in which we own, directly or indirectly, more than 25% (by value) of the shares.



83



---

##### Table of Contents

We must make a separate determination each year as to whether we are a PFIC. As a result, our PFIC status
may change. In particular, because the total value of our assets for purposes of the asset test generally will be calculated using the market price of our ADSs and ordinary shares, our PFIC status will depend in large part on the market price of our
ADSs and ordinary shares which may fluctuate considerably. Accordingly, fluctuations in the market price of the ADSs and ordinary shares may result in our being a PFIC for any year. In addition, the composition of our income and assets is affected
by how, and how quickly, we spend the cash we raise in any offering. If we are a PFIC for any year during which you hold ADS or ordinary shares, we will continue to be treated as a PFIC for all succeeding years during which you hold ADS or ordinary
shares.

If we are a PFIC for any taxable year during which you hold ADSs or ordinary shares, you will be subject to special tax rules with
respect to any excess distribution that you receive and any gain you realize from a sale or other disposition (including a pledge) of the ADSs or ordinary shares, unless you make a mark-to-market election as discussed below.
Distributions you receive in a taxable year that are greater than 125% of the average annual distributions you received during the shorter of the three preceding taxable years or your holding period for the ADSs or ordinary shares will be treated as
an excess distribution. Under these special tax rules:



| |  |  | the excess distribution or gain will be allocated ratably over your holding period for the ADSs or ordinary shares,
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we became a PFIC, will be treated as ordinary
income, and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to each other taxable year will be subject to the highest tax rate in effect for that taxable year and the interest charge generally applicable
to underpayments of tax will be imposed on the resulting tax attributable to each such taxable year.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The tax liability
for amounts allocated to years prior to the year of disposition or excess distribution cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the ADSs or ordinary shares cannot be
treated as capital, even if you hold the ADSs or ordinary shares as capital assets.

Alternatively, a U.S. Holder of marketable
stock (as defined below) in a PFIC may make a mark-to-market election for such stock of a PFIC to elect out of the tax treatment discussed in the two preceding paragraphs. If you make a mark-to-market election for the ADSs or ordinary shares,
you will include in income each year an amount equal to the excess, if any, of the fair market value of the ADSs or ordinary shares as of the close of your taxable year over your adjusted basis in such ADSs or ordinary shares. You are allowed a
deduction for the excess, if any, of the adjusted basis of the ADSs or ordinary shares over their fair market value as of the close of the taxable year. However, deductions are allowable only to the extent of any net mark-to-market gains on the ADSs
or ordinary shares included in your income for prior taxable years. Amounts included in your income under a mark-to-market election, as well as gain on the actual sale or other disposition of the ADSs or ordinary shares, are treated as ordinary
income. Ordinary loss treatment also applies to the deductible portion of any mark-to-market loss on the ADSs or ordinary shares, as well as to any loss realized on the actual sale or disposition of the ADSs or ordinary shares, to the extent that
the amount of such loss does not exceed the net mark-to-market gains previously included for



84

##### Table of Contents

such ADSs or ordinary shares. Your basis in the ADSs or ordinary shares will be adjusted to reflect any such income or loss amounts. If you make a
mark-to-market election, tax rules that apply to distributions by corporations which are not PFICs would apply to distributions by us (except that the lower applicable capital gains rate would not apply).

The mark-to-market election is available only for marketable stock which is stock that is traded in other than de minimis quantities on at
least 15 days during each calendar quarter on a qualified exchange or other market, as defined in applicable Treasury regulations. We expect that the ADSs will continue to be listed and traded on the New York Stock Exchange, which is a qualified
exchange for these purposes, and, consequently, if you are a holder of ADSs, it is expected that the mark-to-market election would be available to you were we to become a PFIC.

If you hold ADSs or ordinary shares in any year in which we are a PFIC, you will be required to file Internal Revenue Service Form 8621 regarding
distributions received on the ADSs or ordinary shares and any gain realized on the disposition of the ADSs or ordinary shares.

You are
urged to consult your tax advisor regarding the application of the PFIC rules to your investment in ADSs or ordinary shares.

Estate Taxes

An individual shareholder who is a citizen or resident of the United States for United States federal estate tax purposes will have
the value of the ordinary shares or ADSs held by such holder included in his or her gross estate for United States federal estate tax purposes.

Information Reporting and Backup Withholding

Dividend payments with respect to ADSs or ordinary shares and proceeds
from the sale, exchange or redemption of ADSs or ordinary shares may be subject to information reporting to the Internal Revenue Service and possible United States backup withholding at a current rate of 28%. Backup withholding will not apply,
however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes any other required certification or who is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status must
provide such certification on Internal Revenue Service Form W-9. U.S. Holders should consult their tax advisors regarding the application of the United States information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against your United States federal income tax
liability, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the Internal Revenue Service and furnishing any required information.

|Item 11. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

Inflation

Since our inception, inflation in China has not materially impacted our results of operations. According to the National Bureau of Statistics of China, the change of consumer price index in China was 3.9%, 1.8% and
1.5% in 2004, 2005 and 2006, respectively.

Foreign Exchange Risk

Most of our sales are currently denominated in U.S. dollars, with the remainder in Renminbi and Euros, while a substantial portion of our costs and
expenses is denominated in U.S. dollars, with the remainder in Renminbi. Therefore, fluctuations in currency exchange rates could have an adverse impact on our financial stability due to a mismatch among various foreign currency-denominated
sales and costs. Fluctuations in exchange rates, particularly among the U.S. dollar, Renminbi and Euro, affect our gross and net profit margins and could result in foreign exchange and operating losses. Our exposure to foreign exchange risk
primarily relates to currency gains or losses resulting from timing differences between signing of sales contracts and settling of these contracts. As of December 31, 2005 and 2006, we held $4.9 million and $29.4 million in accounts receivable,
respectively, most



86

##### Table of Contents

of which were denominated in U.S. dollars. Had we converted all of our accounts receivable as of either date into Renminbi at an exchange rate of RMB7.8041
for $1.00, the exchange rate as of December 31, 2006, our accounts receivable would have been RMB38.4 million and RMB229.1 million as of December 31, 2005 and December 31, 2006, respectively. Assuming that Renminbi appreciates by a
rate of 10% to an exchange rate of RMB 7.0237, we would record a decrease or loss in the fair value of our accounts receivable in Renminbi terms. Our calculation model is based on multiplying our accounts receivable, which are held in U.S. dollar,
by a smaller Renminbi equivalent amount resulting from an appreciation of Renminbi. Our calculation model does not take into account optionality nor does it take into account the use of financial instruments. Based on our calculation model, we
estimate that a 10% appreciation of Renminbi would result in our holding Renminbi equivalents of RMB34.6 million and RMB206.2 million for our accounts receivable as of December 31, 2005 and December 31, 2006, respectively. These amounts
would therefore reflect a theoretical loss of RMB3.8 million and RMB22.9 million for our accounts receivable as of December 31, 2005 and December 31, 2006, respectively.

Furthermore, we translate monetary assets and liabilities denominated in other currencies into Renminbi, our functional currency, at the rates of
exchange in effect at each balance sheet date. We record these exchange gains and losses in the statements of operations. We recorded net foreign currency gains of $103, $260,316 and $1.6 million in 2004, 2005 and 2006, respectively. In 2006, we
entered into two short-term foreign exchange derivative contracts with respect to raw material supplies to protect against volatility of cash flows caused by fluctuations in exchange rates between Renminbi and U.S. dollars. As of December 31,
2006, we had no outstanding foreign exchange hedge contracts. We have not used any other forward contracts, currency options or borrowings to hedge our exposure to foreign currency exchange risk. We cannot predict the impact of future exchange rate
fluctuations on our results of operations and may incur net foreign currency losses in the future. As our sales denominated in foreign currencies, such as Euros, continue to grow, we will consider using derivate instruments to hedge our exposure to
foreign currency exchange risk.

Our financial statements are expressed in U.S. dollars but our functional currency is Renminbi. The
value of your investment in our ADSs will be affected by the foreign exchange rate between U.S. dollars and Renminbi. To the extent we hold assets denominated in U.S. dollars, including the net proceeds to us from our initial public
offering, any appreciation of the Renminbi against the U.S. dollar could result in a change to our statement of operations and a reduction in the value of our U.S. dollar denominated assets. On the other hand, a decline in the value of
Renminbi against the U.S. dollar could reduce the U.S. dollar equivalent amounts of our financial results, the value of your investment in our company and the dividends we may pay in the future, if any, all of which may have a material
adverse effect on the prices of our ADSs.

Interest Rate Risk

Our exposure to interest rate risk primarily relates to interest expenses incurred by our short-term and long-term borrowings, as well as interest income
generated by excess cash invested in demand deposits and liquid investments with original maturities of three months or less. Such interest-earning instruments carry a degree of interest rate risk. We have not used any derivative financial
instruments to manage our interest rate risk exposure. We have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates. However, our future interest expense may increase due to changes in market
interest rates.

We completed our initial public offering
of 530,000,000 ordinary shares, in the form of ADSs, at $18.50 per ADS on December 22, 2006. The aggregate price of the offering amount registered and sold was $98.05 million, of which we received net proceeds of $87.2 million. The net proceeds
from our initial public offering were allocated as follows:



| |  |  | approximately $30.0 million to purchase raw materials;
| | - |  | ------------------------------------------------------



| |  |  | approximately $30.0 million to complete a manufacturing facility for the production of solar cells and to expand our manufacturing lines for the production of
silicon ingots, wafers, cells and solar modules; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the remaining amount for general corporate purposes, including funding our working capital needs.
| | - |  | -------------------------------------------------------------------------------------------------

As of December 31, 2006, our cash resources amounted to $93,380,212, comprising of cash on hand and demand deposits.

In addition, in January 2007, the underwriters exercised their over-allotment option for the purchase of an additional 510,300 ADSs, generating net
proceeds of $8.8 million. The net proceeds will be used for general corporate purposes.

In June 2007, we completed our follow-on public
offering of ADSs sold by us and certain selling shareholders. In this follow-on public offering, we issued and sold 360,001,600 ordinary shares, in the form of ADSs, at $45.00 per ADS on June 6, 2007. The aggregate price of the offering amount
registered and sold was approximately $243.3 million, of which we received net proceeds of approximately $154.3 million. The net proceeds from our follow-on public offering have been allocated as follows:



| |  |  | approximately $125 million to expand our manufacturing lines for the production of silicon ingots, wafers, solar cells and solar modules;

|Item 15. | CONTROLS AND PROCEDURES
|-------- | -----------------------

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this annual report, our management,
with the participation of our chief executive officer and our chief financial officer, has performed an evaluation of the effectiveness of our disclosure controls and procedures within the meaning of Rules 13a-15e and 15d-15(3) of the Securities
Exchange Act of 1934. Based on their evaluation of the effectiveness of our disclosure controls and procedures as described above, our chief executive officer and chief financial officer have concluded that, solely because of the material weaknesses
in internal control over financial reporting described below, as of the end of the period covered by this annual report, our disclosure controls and procedures were effective.

In May 2007, our auditors, Deloitte Touche Tohmatsu CPA Ltd. reported to us that, in the course of its audit of our financial statements for the year
ended December 31, 2006, it had identified three material weaknesses and certain other deficiencies in our internal control and financial reporting. The material weaknesses identified by our independent registered public accounting firm include
(i) insufficient accounting resources to properly identify adjustments, analyze transactions and prepare financial statements in accordance with U.S. GAAP, (ii) a lack of formal accounting policies and procedures for U.S. GAAP to ensure
that our accounting policies and procedures are appropriately or consistently applied, and (iii) weaknesses in our inventory management. Following the identification of these material weaknesses and other deficiencies, we have undertaken
remedial steps to address them, including hiring additional staff, training our new and existing staff and augmenting our financial information technology systems.

In addition, since the beginning of 2007, we have engaged an advisory firm to advise us about complying with requirements of the Sarbanes-Oxley Act, have formed a task force led by senior management members in
pursuing compliance with the requirements of the Sarbanes-Oxley Act and are currently continuing to recruit more senior level staff to ensure we complete the process according to the timetable.

Changes in Internal Controls over Financial Reporting

There were no adverse changes in our internal controls over financial reporting that occurred during the period covered by this annual report that have materially affected, or are reasonably likely to materially affect, our internal
controls over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Trina Solar Limited

We have audited the accompanying
consolidated balance sheets of Trina Solar Limited and subsidiaries (the Company) as of December 31, 2004, 2005, and 2006, and the related consolidated statements of operations, shareholders equity and comprehensive income
(loss), and cash flows for each of the three years in the period ended December 31, 2006, and the related financial statement schedule included in Schedule I. These financial statements and the related financial statement schedule are the
responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Companys internal control over financial reporting. Accordingly, we
express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our
opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Trina Solar Limited and subsidiaries as of December 31, 2004, 2005, and 2006, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 2006, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the related financial statement schedule, when
considered in relation to the basic financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

TRINA SOLAR LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2004, 2005 AND 2006

(In U.S. dollars)

1. Organization and Principal Activities

Trina Solar Limited, (Trina) was incorporated in the Cayman Islands under the laws of the Cayman Islands on March 14, 2006.

Trina, its subsidiaries and variable interest entity (VIE) (collectively the Company) are principally engaged in the
manufacturing and selling of solar modules in the Peoples Republic of China (the PRC) and overseas markets. During the periods covered by the consolidated financial statements, substantially all of the Companys business was
conducted through an operating subsidiary, Changzhou Trina Solar Energy Co., Ltd. (Trina China), established in the PRC on December 26, 1997. Tianhe Research Institute Co., Ltd. (Tianhe Research), a former subsidiary of
Trina China, was established in the PRC on May 19, 2003 for conducting research and development and was disposed of on December 29, 2004. In addition, Trina China consolidates the operations of Sun Era Industries Limited (Sun
Era) that was incorporated in the British Virgin Islands on October 18, 2002 by the founder of Trina China and his wife to procure raw materials, provide sales support and make toll manufacturing purchases exclusively for Trina China and
was determined to be a VIE of Trina China. We believe through the related party nature of the arrangement to establish Sun Era that we own the majority of its outstanding equity ownership rights and we believe that we are the primary beneficiary of
Sun Era. We have consolidated Sun Era since its establishment. On July 18, 2006, the Company established a Hong Kong incorporated wholly-owned subsidiary, Top Energy International, Ltd. (Top Energy) to assist the Company in
procuring raw materials and trading silicon wafers.

In connection with pre-IPO planning, the Company initiated a restructuring process.
Trina was established in March 2006 and issued 10,000 ordinary shares at par value of $1.00 per share to the nominees of the then existing equity owners of Trina China, based on their proportionate ownership in Trina China. In April 2006, the issued
10,000 ordinary shares were sub-divided into 1,000,000,000 ordinary shares at par value of $0.00001 each. In May 2006, the Company issued 545.8 million Series A preferred shares for cash proceeds of approximately $40 million. Trina then
acquired the entire equity interest in Trina China from the then existing equity owners by paying nominal consideration to the foreign equity owners and an aggregate of approximately RMB40.7 million (equivalent to $5.1 million) to the PRC equity
owners. The consideration of $5.1 million paid to these PRC equity owners was regarded as a return of capital upon restructuring. These PRC equity owners then advanced the amounts they received back to Trina China. Trina China fully repaid these
advances in October 2006 while these PRC equity owners, through their designated nominee shareholders of the Company, contributed in aggregate of approximately $4.9 million as a gift or donated capital to the Company in October and November 2006.
The restructuring process has resulted in the nominees of the former equity owners of Trina China holding ordinary shares of the Company consistent with the percentage of ownership of the former equity owners in Trina China and has been accounted
for as a recapitalization. Accordingly, the consolidated financial statements include the results of Trina China prior to the recapitalization with all share and per share data being restated to give retroactive effect of this restructuring and the
share capital represents the capital amount of the Company as if the restructuring has been completed as of the earliest period presented.

2. Summary
of Principal Accounting Policies

(a) Basis of presentation

These consolidated financial statements are prepared and presented in accordance with accounting principles generally accepted in the United States of
America (US GAAP) and include the accounts of the Company and its subsidiaries and VIE. We have eliminated all inter-company transactions and balances during consolidation.



F-7

##### Table of Contents

(b) Use of estimates

The preparation of financial statements in conformity with US GAAP requires us to make estimates and assumptions that affect reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Significant accounting estimates reflected in our financial statements include provision for doubtful accounts, provision for warranty expenses, valuation of deferred tax assets, valuation of the useful lives of our intangible assets and property,
plant and equipment, valuation of share-based compensation and related forfeiture rates.

(c) Cash and cash equivalents

Cash and cash equivalents consist of cash on hand and demand deposits, which are unrestricted as to withdrawal and use, and which have maturities of
three months or less when purchased.

Restricted cash comprises amounts pledged to our banks to secure notes payable and letters of credit
facilities. These deposits carry fixed interest rates and will be released when the related letters of credit are settled by us. As of December 31, 2004, 2005 and 2006, the Companys notes payable of $241,668, $nil and $nil are secured
with the Companys bank deposits of $241,668, $nil and $nil. As of December 31, 2004, 2005 and 2006, the Company issued letters of credit of $nil, $526,975 and $7,817,975 secured by the Companys bank deposits of $nil, $526,975 and
$5,003,871, respectively.

(d) Inventories

We report our inventories at the lower of cost or market. We determine cost on a weighted-average basis. These costs include direct material, direct labor, toll manufacturing costs, inventory movement and fixed and
variable indirect costs, including depreciation and amortization.

We regularly review the cost of inventory against its estimated fair
market value and will record a lower of cost or market write-down for inventories that have a cost in excess of estimated market value. We also provide obsolescence reserves for silicon materials that may not meet our required specifications for
inclusion in our manufacturing process. These materials are periodically sold for scrap.

We have outsourced portions of our manufacturing
process, including cutting ingots into wafers, and converting wafers into solar cells, to various third-party manufacturers. These outsourcing arrangements may or may not include transfer of title of the raw material inventory (silicon, ingots or
wafers) to the third-party manufacturers. Such raw materials are recorded as raw materials inventory when originally purchased from suppliers.

For those outsourcing arrangements in which title does not transfer, we maintain the inventory in the balance sheet as raw materials inventory while it is in physical possession on the third-party manufacturers. Upon receipt of the
processed inventory from the third-party manufacturers, it is reclassified to work-in-progress inventory with the processing fee capitalized as a cost of inventory.

For those outsourcing arrangements in which title (including risk of loss) does transfer to the third-party manufacturer, we are constructively obligated to repurchase the inventory once processed. To accomplish this,
we enter into raw materials sales agreements and processed inventory purchase agreements simultaneously with the third-party manufacturer. In such instances, we maintain the inventory in the consolidated balance sheets while it is in the
physical possession of the third-party manufacturer. The cash received from the third-party manufacturer is classified as a current liability on the balance sheet and not as revenue or deferred revenue. Upon receipt of the processed inventory,
it is reclassified to work-in-process inventory and a processing fee is paid to the third-party manufacturer. Cash payments for outsourcing arrangements which require prepayment for repurchase of the processed inventory are classified as
current assets on the balance sheet. There is no right of

offset for these arrangements and accordingly, the associated assets and liabilities remain on the balance sheet until the processed inventory is settled.

We do not recognize revenue or costs of revenue until our finished solar modules are delivered and title has passed to our customers.

(e) Property, plant and equipment

We report our property, plant and equipment at cost, less accumulated depreciation and amortization. Costs include the prices paid to acquire or construct the assets, including capitalized interest during the
construction period, and any expenditures that substantially extend the useful life of an existing asset. Interest capitalized into property, plant and equipment was $nil, $52,731 and $74,685 during 2004, 2005 and 2006, respectively. We expense
repair and maintenance costs when they are incurred.

We compute depreciation expense using the straight-line method over the estimated useful lives of
the assets presented below. We amortize leasehold improvements over the lesser of their estimated useful lives or the term of the lease. Capitalized costs related to assets under construction are not depreciated until construction is complete and
the asset is ready for its intended use. Repairs and maintenance are expensed as incurred.

|Motor vehicles                               |  | 5    
|Electronic equipment, furniture and fixtures |  | 5    

(f) Intangible assets

Our land use rights are reported at cost, less accumulated amortization. We amortize the land use rights on a straight-line basis over 50 years based on
the contractual life of the right.

(g) Long-lived assets

We evaluate our long-lived assets and definite-lived intangibles for impairment whenever events or changes in circumstances indicate that the carrying
amount of an asset may not be recoverable. When these events occur, we measure impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventual
disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, we would recognize an impairment loss equal to the excess of the carrying amount over the fair value of the assets.

(h) Income taxes

We recognize
deferred income tax assets and liabilities for the future tax consequences attributable to differences between the tax basis of assets and liabilities and their reported amounts in the financial statements and for net operating loss carryforwards
and credits. We measure deferred tax assets and liabilities by using enacted statutory tax rates expected to apply to taxable income in the years in which we expect those temporary differences to be recovered or settled. We recognize the effects of
any changes to applicable tax rates in the



F-9

##### Table of Contents

period in which the new rate is enacted. Our deferred tax assets are reduced by a valuation allowance when we determine it is more likely than not that some
portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of each relevant taxing authority. We classify the components of our deferred tax assets and liabilities individually
as current and non-current based on the characteristics of the underlying assets and liabilities, or on the expected period of their use, if not related to an asset or liability.

(i) Revenue recognition

We
recognize revenue for product sales when persuasive evidence of an arrangement exists, delivery of the product has occurred and title and risk of loss has transferred to the customer, the sales price is fixed or determinable, and the collectibility
of the resulting receivable is reasonably assured. Our sales agreements typically contain customary product warranties but do not contain any post-shipment obligations nor any return or credit provisions.

We recognize sales of our solar modules based on the terms of the specific sales contract. Generally, we recognize sales when we have delivered our
products to our customers designated point of shipment, which may include commercial docks or commercial shipping vessels. Some of our contracts may stipulate that we must defer recognizing revenue until we have delivered the product to our
customers location and we receive documentation that they have accepted delivery.

We recognize revenue on sales of our aluminum
siding when we have delivered it to our customers location and they have accepted delivery.

We recognize revenue related to our
solar systems integration on the percentage-of-completion method. We estimate our revenues by using the cost-to-cost method, whereby we derive a ratio by comparing the costs incurred to date to the total costs expected to be incurred on the project.
We use the ratio computed in the cost-to-cost analysis by applying it to the contract price to determine the estimated revenues earned in each period. When we determine that total estimated costs will exceed total revenues under a contract, we
record a loss accordingly.

(j) Shipping and handling costs

Customer payments of shipping and handling costs are included in our net revenues. Shipping and handling costs relating to solar module sales of $3,357,
$7,187 and $194,948 are included in selling expenses for the years ended December 31, 2004, 2005 and 2006, respectively. Shipping and handling costs relating to inventory purchases of $56, $18,065 and $109,257 are included as a component of
cost of revenues for the years ended December 31, 2004, 2005 and 2006, respectively.

(k) Research and development

Research and development costs are incurred during the period we are developing new products or refining existing products or technologies. These
costs are expensed as incurred until the products have been developed and tested and are ready for production and sale.

We periodically
qualify for grants from the PRC government for achieving certain research and development milestones. We record these grants as an offset to our research and development expenses in the periods in which we earn them. Grants that we receive prior to
when we achieve the specified milestone are reported as a liability. We recorded $116,762, $151,638 and $198,693 of earned grants as reductions of research and development expenses for the years ended December 31, 2004, 2005 and 2006,
respectively.

(l) Product warranties

We provide a limited warranty to the original purchasers of our solar modules for two years following delivery for defects in materials and workmanship.
We provide a minimum power output warranty for up to 25 years following delivery. We accrue warranty costs as we recognize revenues. Due to our limited solar module manufacturing history, we do not have a significant history of warranty claims. We
currently accrue for product warranties at 1% of solar module sales based on our assessment of industry norms which also represents our best estimate to date. Should we begin to experience warranty claims differing from our accrual rate, we would
prospectively revise the warranty accrual rate.

(m) Advances from customers

We frequently require that our customers pay us for our solar modules prior to the delivery of the products. These advance payments are recorded as
advances from customers under our current liabilities.

(n) Foreign currency translation and foreign currency risk

Our functional currency is the Renminbi (RMB), the currency of the PRC. Transactions that we denominate in other currencies are recorded in
RMB at the rates of exchange on the date when the transactions occur. We translate monetary assets and liabilities denominated in other currencies into RMB at the rates of exchange in effect at each balance sheet date. We record these exchange gains
and losses in the statements of operations.

We have chosen the US dollar as our reporting currency. Our assets and liabilities are
translated at the exchange rate at each balance sheet date and we use an average exchange rate for the period to translate our statements of operations. We report the adjustments that result from these translations as a component of our
shareholders equity under other comprehensive income.

The RMB is not a freely convertible currency. The PRC State Administration for
Foreign Exchange, under the authority of the PRC government, controls the conversion of RMB into foreign currencies. The value of the RMB is subject to changes in central government policies and to international economic and political developments
affecting supply and demand in the China foreign exchange trading system market. Our cash and cash equivalents and restricted cash denominated in RMB amounted to $3,298,173, $363,156 and $6,359,816 as of December 31, 2004, 2005 and 2006,
respectively.

(o) Concentrations of credit risk

Our financial instruments that potentially expose us to concentrations of credit risk are primarily our trade accounts receivable. We conduct credit evaluations of our customers but generally have not required
collateral or other security interests from our customers when we grant them credit. We make a provision for estimated uncollectible accounts based primarily on the age of the receivables but also when we identify potential payment problems with
specific customers.

We have not had significant collections issues for receivables generated from sales of our solar modules. We often
require significant down payments or letter of credit by our customers prior to shipment and may require settlement via wire transfer within 30 days of shipment as these are typically export sales.

Our historical write-offs have been within management estimates.

(p) Fair value of financial instruments

Our trade accounts receivables, other receivables, advances
to suppliers, trade accounts payable, and short-term borrowings all approximate their fair values due to their short-term maturity dates.

Our long-term borrowings had carrying values approximating their fair values of December 31, 2004, 2005 and 2006.

(q) Share-based compensation

The Company has adopted SFAS No. 123R, Share-based Payment, which requires that share-based payment transactions with employees, such as
restricted shares, be measured based on the grant-date fair value of the equity instrument issued and recognized as compensation expense over the requisite service period, with a corresponding addition to paid-in capital. Under this method,
compensation cost related to employee restricted shares is measured at the grant date based on the fair value of the award and is recognized over the period during which an employee is required to provide service in exchange for the award, which
generally is the vesting period.

(r) Derivative financial instruments

The Companys primary objective for holding derivative financial instruments is to manage currency risk. The Company records derivative
instruments as assets or liabilities, measured at fair value. The recognition of gains or losses resulting from changes in fair values of those derivative instruments is based on the use of each derivative instrument and whether it qualifies for
hedge accounting.

In 2006, the Company entered into certain foreign exchange contracts to protect against volatility of future cash flows
caused by the changes in foreign exchange rates associated with the outstanding accounts payable. The foreign exchange hedge contracts do no qualify for hedge accounting and, as a result, the changes in fair value of the foreign currency hedge
contracts are recognized in the statement of operations.

As of December 31, 2006, the Company has no outstanding foreign exchange
hedge contracts.

(s) Income per share

Basic income per share is computed by dividing net income by the weighted average number of ordinary shares outstanding during the period. Diluted income per ordinary share reflects the potential dilution that could
occur if securities or other contracts to issue ordinary shares were exercised or converted into ordinary shares. Ordinary share equivalents are excluded from the computation in loss periods as their effects would be anti-dilutive.

The following table sets forth the computation of the basic and diluted income from continuing operations per share for the periods indicated:

Since the Series A preferred shareholders had the right to participate equally with the common
shareholders in any dividends declared, the Company has presented 2006 basic and diluted earnings per share using the two-class method.

(t) Recently issued accounting pronouncements

In June 2006 the FASB released Interpretation No. 48, Accounting for
Uncertainty in Income Taxesan Interpretation of FASB Statement No. 109, (FIN 48) which prescribes a recognition threshold and a measurement attribute for tax positions taken, or expected to be taken, in a tax return. FIN 48
also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. We are required to adopt FIN 48 as of January 1, 2007. We do not anticipate that the adoption of this
interpretation will have a material impact on our financial position, cash flow or results of operations.

In June 2006, the Emerging
Issues Task Force (EITF) reached a consensus on Issue No. 06-3, How Taxes Collected from Customers and Remitted to Governmental Authorities Should be Presented in the Income Statement (That Is, Gross Versus Net
Presentation) (EITF 06-3). The scope of EITF 06-3 includes sales, use, value added and some excise taxes that are assessed by a governmental authority on specific revenue-producing transactions between a seller and customer. EITF
06-3 states that a company should disclose its accounting policy (i.e. gross or net presentation) regarding the presentation of taxes within its scope, and if significant, these disclosures should be applied retrospectively to the financial
statements for all periods presented. EITF 06-3 is effective for interim and annual reporting periods beginning after December 15, 2006. The Company is currently evaluating the impact, if any, of this statement on its consolidated financial
statements and related disclosures.

In September 2006, the FASB released FAS 157, Fair Value Measurement (FAS 157). FAS 157
defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. FAS 157 applies under other accounting pronouncements that require or permit
fair value measurements and the FASB had previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, FAS 157 does not require any new fair value measurements. FAS157 is effective for
financial statements issued for fiscal years beginning after November 15, 2007. We are in the process of assessing the impact of the adoption of FAS 157 on the Companys financial position or results of operations.

In February 2007, the FASB released FAS 159, The Fair Value Option for Financial Assets and Financial Liabilities (FAS 159). FAS 159 permits
entities to choose to measure certain financial instruments at fair value to expand the use of fair value measurement and improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by
measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. FAS 159 is effective as of the beginning of an entitys first fiscal year that begins after November 15, 2007. We are in the
process of assessing the impact of the adoption of FAS 159 on the Companys financial position or results of operations.

3. Discontinued
Operations

Due to the continuing erosion of the gross margins related to the aluminum siding business and the Companys decision
to focus its future efforts on the solar module business, the Company decided to discontinue the aluminum siding business, which previously represented a business segment of the Company, in June 2006. In December 2006, Trina China entered into a
contract to sell the assets of the aluminum sidings business, including the land use rights of 7,633 square meters, buildings on the land and equipment, for a total price of RMB5.8 million ($742,761) to Mr. Wu Weifeng and Mr. Wu Weizhong,
the brothers of Ms. Chunyan Wu, one of our directors and wife of Mr. Jifan Gao, the Chairman of our company. These assets include land use rights of 7,633 square meters, buildings on the land and equipment. The sales price was determined
based on the

higher of the two formal offers, one of which came from a third party unrelated to the Company, and was approved by the audit committee and all the
independent directors. The resulting loss on disposal of $244,130 is reflected in loss on discontinued operations for the year ended December 31, 2006.

Ms. Chunyan Wu, wife of Mr. Jifan Gao, transferred certain beneficial interests in the Company to certain employees of the Company for their past services through the transfer of approximately 29% ownership interest in Perseverance
International Investment Limited (Perseverance), a shareholder of the Company, which is controlled by Ms. Wu. The transfer of Perseverance shares was made for no consideration. Perseverance was established for the sole purpose of
holding a portion of equity interest in the Company and is not engaged in any other business. On the date of the grant, the Company was a shell company and as such, there was no value attributable to the interest transferred. As discussed in note 1,
the Company acquired all the equity interests in Trina China in May 2006. This restructuring transaction resulted in a new measurement date for the beneficial interests previously granted to these employees. As such, the Company recorded a
compensation charge of $2,288,116, which was based on approximately 29% of the aggregate fair value of 106,400,000 ordinary shares of the Company held by Perseverance, or $0.0710 per share on the new measurement date.

The fair value of the ordinary shares was based upon the May 2006 issuance of Series A preferred shares. Based on the consideration paid for the Series A
preferred shares, we determined an overall equity of approximately $107 million for our company after the transaction. The interest in the equity value of the Company includes both preferred shares and ordinary shares. The fair value of the equity
interest was allocated to preferred shares using the option pricing method. The fair value of the ordinary shares was calculated as the residual, or total equity value less the fair value of the preferred shares. Under the option pricing method, the
Company treated the preferred shares as a call option on the Companys equity value, with the excise price based on the liquidation preference of the preferred shares. Because a call option is used, the option pricing method

commonly used is the Black-Scholes model, which takes into account the strike price of the option, risk free interest rates, and the volatility of the
Company. Because the Company is a private company, the Company approximates volatility using the historical volatility of comparable publicly traded companies. The significant assumptions used in the Black-Scholes model include: expected life of 8
months; risk-free interest rate of 3.8%; volatility of 29.9%; and no dividend yield.

Based on this methodology, we calculated the residual
fair value of our ordinary share to be $0.0710 per share.

On July 24 and August 10, 2006, the Company issued 45,725,760 shares
to certain officers and employees at $0.00001 par value with a fair value of $0.1096 as of the grant date. The shares are subject to repurchase by the Company and can be released from the repurchase in the amount of 1/5 per annum on the
anniversary of the grant date until 2011 for as long as the officer or employee is employed with the Company.

A summary of the restricted
share activity is as follows:

The fair value of the ordinary shares for both our July 24 and August 10, 2006
restricted shares grants was based on a retrospective valuation conducted by an independent third party. This valuation used a combination of a market approach with a 60% weighting and an income approach with a 40% weighting in order to derive the
equity value of the Company. The valuation model then allocated the equity value between the ordinary shares and the preference shares in a manner consistent with that of our May 2006 valuation described above. The significant assumptions used in
the Black-Scholes model included: expected life of 3.7 years; risk-free interest rate of 3.8%; no dividend yield; and volatility of 65.8%. Based on this methodology, we calculated the residual fair value of our ordinary shares to be $0.1096 per
share.

Trina China is a foreign invested enterprise located in Changzhou, Jiangsu Province, and was recognized
as a high technology enterprise. Our enterprise income tax rate is derived from the standard enterprise income tax rate of 24% for this district, reduced for applicable exemptions.

In accordance with the tax legislations applicable to foreign investment enterprises (FIE), we are entitled to exemptions from PRC enterprise
income tax for the two years commencing from our first profit-making year of operations, after offsetting all unexpired tax losses carried forward from previous years, and thereafter, entitled to a 50% relief from PRC enterprise income tax for the
next three years (the Tax Exemption). 1999 was the first year we commenced benefiting from the Tax Exemption. In 2004 we were granted a further three year extension in the 50% relief from PRC enterprise income tax of 24%. As a result,
Trina China was subject to preferential enterprise income tax rates of 12% in 2004, 2005 and 2006.

Tianhe Research is subject to an
enterprise income tax rate of 33%. We have not provided for any PRC enterprise income taxes for Tianhe Research as we incurred losses in that company in 2004 prior to disposal.

Reconciliation between the provision for income tax computed by applying the applicable enterprise income tax rate of 24% to income before income taxes
and the actual provision of income taxes is as follows:

reserve fund and a staff welfare and bonus fund which is non-distributable. Appropriations to such reserves are made out of net profit after taxation of
Trina China. Trina China is required to transfer 10% of its profit after taxation, as reported in our PRC statutory financial statements, to the general reserve fund until the balance reaches 50% of its registered capital. The general reserve fund
may be used to make up prior year losses incurred and, with approval from the relevant government authority, to increase capital. Trina China is also required to allocate a portion of its net profit after taxation to its staff welfare and bonus
fund, which may not be distributed to its equity owners. However, the amount to be allocated to the staff welfare and bonus fund is at the sole discretion of the board of directors. PRC regulations currently permit payment of dividends only out of
Trina Chinas accumulated profits as determined in accordance with PRC accounting standards and regulations. As a result of these PRC laws and regulations, Trina China is restricted in its ability to transfer a portion of net profit to us in
the form of dividends.

The amount of the non-distributable general reserve fund was $175,221, $506,367 and $1,776,998 as at
December 31, 2004, 2005 and 2006, respectively. The amount of the welfare fund and bonus fund was $Nil, $Nil and $Nil as at December 31, 2004, 2005 and 2006, respectively, as Trina China elected not to make any appropriations to this fund.

The amount that is not subject to restrictions, and which may be transferred from Trina China in the form of dividends, loans or advances,
is $Nil, $2,835,992 and $14,271,675 as at December 31, 2004, 2005 and 2006, respectively.

As a result of these PRC laws and
regulations, the Companys PRC subsidiary is restricted in its ability to transfer the registered capital and general reserve fund to the Company in the form of dividends, loans or advances and the restricted portion amounted to $3,930,221,
$7,181,367 and $41,171,998 of December 31, 2004, 2005 and 2006, respectively.

The Company obtained short-term financing from Changzhou Fulai Property Development Co., Ltd., a related
party controlled by Mr. Canfang Liu and Mr. Lai Shing Yip, beneficial shareholders of the Company, and Jiangsu Jiuzhou Investment Group Co., Ltd., a related party controlled by Mr. Canfang Liu. The amount and the duration of these
short-term financings ranged from RMB8 million ($1.02 million) to RMB20 million ($2.56 million) and from four days to 34 days, respectively. Interest was charged at 7.2% per annum. Trina recorded $20,335 in interest expenses related to these
financings during the year ended December 31, 2006. Both principal and interest were repaid prior to December 31, 2006.

In
connection with the restructuring of Trina in 2006, certain of the former equity holders of Trina China may be subject to income tax on capital gain while transferring their equity interest in Trina China to Trina. Trina or Trina China may be
subject to withholding obligation with respect to the income tax on their capital gains. These former equity holders of Trina China have provided indemnity to the Company against such withholding obligations or liabilities due to or imposed by the
PRC tax authority arising from the restructuring.

In December 2006, Trina China entered into a contract to dispose of the plant and
equipment of the aluminum siding business for a total price of RMB5.8 million ($742,761) to Mr. Weifeng Wu and Mr. Weizhong Wu, the brothers of Ms. Chunyan Wu, one of our directors and wife of Mr. Jifan Gao, the Chairman of our
company. These assets include land use rights of 7,633 square meters, buildings on the land and equipment. The sales price was determined based on the higher of the two formal offers, one of which came from a third party unrelated to the Company,
and was approved by the audit committee and all the independent directors. The resulting loss on disposal of $244,130 is reflected in loss on discontinued operations for the year ended December 31, 2006.

Commitments to purchase property, plant and equipment as at December 31, 2005 and 2006 relate
to building and machinery associated with expansion of our solar module business.

b) Operating lease commitments

We had operating lease agreements principally for our office properties in the PRC. These leases had expired by December 31, 2006 and were not
renewed. Our rental expense was $60,647, $50,404 and $3,515 for the years ended December 31, 2004, 2005 and 2006, respectively.

c)
Contingencies

As of December 31, 2005, we were contingently liable to the local government with respect to accumulated
under-payment of social insurance and employee welfare benefits which were estimated to be $94,894 and recognized as a liability by the Company. Subsequently in 2006, we have settled with the local government authority in relation to the outstanding
payments and indicated that no further penalty would be charged to the Company. However, the Company might still be subject to fines or penalty for the underpayment in the past as of December 31, 2006. Mr. Jifan Gao has agreed to indemnify us
against any future loss or penalty for such past non-compliance.

As of December 31, 2005, we were contingently liable to the local
government for commencing construction of new buildings without acquiring all required construction and environmental permits. Subsequently in 2006, we have obtained all of the outstanding permits. However, the Company might still be

subject to fines or penalties for the past non-compliance as of December 31, 2006. Mr. Jifan Gao has agreed to indemnify us against any future economic
loss or penalty as a result of such non-compliance.

In connection with the restructuring of Trina in 2006, certain former shareholders of
Trina China may be subject to income tax on capital gains from transferring their equity interests in Trina China to Trina. Trina or Trina China may be subject to withholding obligations with respect to the income tax on capital gains. These former
shareholders of Trina China have provided indemnity to the Company against such withholding obligations or liabilities due to or imposed by the PRC tax authority that may arise out of the restructuring.

18. Segment Information

Prior to electing to
discontinue our aluminum siding business, the Company was operating in three operating segments, namely solar modules, aluminum siding and system integration. Upon the election to discontinue the aluminum siding business in June 2006, we have been
operating our business under the two remaining segments. We have retroactively reclassified all of the segment activity to reflect our current segment structure. The results of the system integration business are included as non-allocated in the
segment information as the amounts involved are insignificant.

Our solar operations comprises the production of monocrystalline silicon
ingots and wafers, from which solar cells are fabricated, and the subsequent assembly and marketing of solar modules, which are panels packed with interconnected solar cells that convert sunlight into electricity.

Our system integration operations comprise the design, installation and testing of interconnected solar modules with system components such as batteries
and inverters, to produce and reserve electricity.

Chief operating decision maker is the CEO of the Company.

The following tables summarize the selected revenue, expense and balance sheet information for each operating segment:

The accounts receivable from the customers with the largest receivable balances represent 100%,
37% and 35% at December 31, 2004, 2005 and 2006, respectively.

20. Subsequent Events

On January 1, 2007, the Company issued 5,120,994 shares to certain officers and employees at $0.00001 par value with a fair value of $0.1915 as of
the grant date. The shares are subject to repurchase by the Company, and 3,380,994 shares and 1,740,000 shares can be released from the repurchase in the amount of 1/5 and 1/3, respectively, per annum on the anniversary of the grant date until
2012 and 2010, for as long as the officer or employee is employed with the Company.

In February 2007, the State Tax Bureau of Changzhou
High-Tech Industry Development Zone (the STB), the location in which Trina China is registered, approved Trina Chinas application for tax holiday in conjunction with an increase of $32,720,000 in its registered capital, from
$7,280,000 in August 2005 to $40,000,000 in July 2006. In accordance with the approval of the STB, Trina China is exempt from income taxes for 81.8%, representing the proportion of its increase in registered capital in 2006 of its taxable profit
from August 2006 to December 2007, followed by a 50% reduction in its tax rate from 2008 to 2010.

The 2006 income tax was calculated based
on a tax rate of 12% as the STB did not issue their approval until February 2007. If the STB approval had been issued in 2006, the income tax provision and net income for 2006 would have been reduced and increased by approximately $0.7 million,
respectively.

We completed our follow-on public offering in June 2007 of ADSs sold by us and certain selling shareholders. In this
follow-on public offering, we issued and sold 360,001,600 ordinary shares and certain selling shareholders sold 180,626,400 ordinary shares, in the form of ADSs, at $45.00 per ADS on June 6, 2007. The aggregate price of the offering amount
registered and sold (including secondary sale) was approximately $243.3 million, of which we received net proceeds of approximately $154.3 million.
