Twenty-Five Years of Building Enterprises, Pursuing the Light 
of Trina Solar's Heart
From 1997 to 2022, Trina Solar has travelled 25 years, spanning a quarter of a century, on the road to its dream 
of becoming a photovoltaic company. Since early days, Trina Solar has adhered to the mission of "Solar Energy 
for All", and has always been committed to leading the way in smart solar energy solutions for a net-zero future. 
Looking back on the past 25 years, Trina Solar has made great strides and has never lost sight of its 
commitment.
In 2000, we developed and manufactured the first solar energy building system model house ("Sunshine Hut") 
in China, which was exhibited at the "Trina Solar East-West Development Plan Conference" held at the China 
Science and Technology Hall and became one of the contents of CCTV's promotion for the Green Olympics to 
IOC officials. Since then, Trina Solar has taken the lead in the industry to propose and fully implement a vertical 
integration strategy, gradually forming a PV industry chain of silicon rods - wafers - cells - modules, ensuring 
that the Company has its own raw materials and market while developing technology at a high speed. In 2005, 
Trina Solar deepened its internationalization process and expanded its sales network to all over the world, being 
listed shortly after, in 2006, on the New York Stock Exchange. In 2020, Trina Solar made its A-share debut on 
the Science and Technology Venture Board, becoming the first PV company to be listed on the Board covering 
PV products, PV systems and smart energy. From our humble beginnings, we have grown to become a top-tier 
global PV module manufacturer.
Trina Solar has adhered to the concept of sustainable development during this period. With innovation, 
branding, and globalization as its three main pillars, Trina Solar has accurately predicted the industry trend and 
actively searched for and laid out medium- and long-term growth points while reasonably balancing its existing 
advantages. We are convinced that innovation is the first driver of enterprise development and growth, and 
even in the most dismal period of the market, Trina Solar still continues to improve the ability of technological 
innovation. In 2007, we increased module capacity from 150 MW to 350 MW. In 2010, we became the first 
"Industry Shaper" in the solar industry at the World Economic Forum in Davos, ranking among the top tier of 
global PV companies. In 2014, the Company set and refreshed world records for crystalline silicon cell efficiency 
and module power seven times, including four world records for crystalline silicon cell efficiency and three 
13
world records for crystalline silicon module power, and was awarded the "National Torch Plan Key Hightech 
Enterprise" and the "Excellent Low Carbon Green Management Award" by the British Standards Institution (BSI). 
With technological innovation and brand enhancement, Trina has been the first in the world in total module 
shipments since 2014, with the cumulative module shipments exceeding 30 GW in 2016. In 2018, Trina Solar 
won the China Grand Awards for Industry, becoming the first PV company to win this award. In 2021, Trina 
Solar's "Key Technologies and Applications of High-efficiency and Low-cost Silicon Solar Cell Meter Interface 
Manufacturing" project won the National Technological Invention Award (NTIA) at the 2020 National Science 
and Technology Awards Conference. This was the first time that the field of PV technology in China won the 
National Technological Invention Award. 
In recent years, Trina Solar has launched six new key strategies: innovation, branding, globalization, platform 
development, smart technologies, and synergy between the financial and industrial sectors. In 2021, we 
released 670W+ ultra-high-power modules, leading the industry into the 600W+ era, and led the establishment 
of the 600W+ Photovoltaic Open Innovation Ecological Alliance. In 2022, Trina Solar, together with CEEC and 
CATL, jointly initiated the establishment of the China Energy Storage Industry Innovation Alliance. Our original 
intention for development still strongly guides our way, as we continue to strive to feed the industry and the 
country, and change from being a follower in the PV industry to a promoter, leading it.
Up to 2022, we have set 25 new world records, leading a new generation of advanced cell technology and 
accelerating the industry to a new era of N-type; The "Intelligent Tracking Performance Test Method for PV 
Tracking Brackets" led by Trina Solar was the first tracker intelligence project to be included in the industry 
standards; we were included in the top 100 Chinese multinationals list issued by the China Enterprise 
Confederation in 2022, ranking first in the PV industry; we were also selected for the list "Top 100 Innovators 
Leading the Energy Transition" put together by Reuters, becoming the only Chinese company in the list. 
In the first 25 company years, the photovoltaic products of Trina Solar have entered numerous households and 
gone around the world, responding to the original intention of "Solar Energy for All" from when the Company 
was founded. Standing at the starting line of the next 25 years, Trina Solar will always take innovation as its 
first development strategy and core driving force, build a comprehensive and leading science and technology 
innovation system, continue to promote the development of photovoltaic technology innovation industry 
research in continuous R&D breakthroughs, help accelerate the construction of a clean, low-carbon, safe, and 
efficient new energy system, while continuing to lead the industry's green development, reach ecological union,

In order to ensure product and system reliability, Trina Solar has reinforced the 600W+ 
module bezel and tracker, and adopted several patented technologies to reduce the 
failure rate. Take the tracker as an example, it adopted Trina's patented spherical bearing 
technology, which well solved the installation quality hidden problems that may be caused by 
the bending of the column, the undulation of the terrain, the settlement, and the deviation of 
the foundation construction, and reduced the chance of wind and sand jamming the rotating 
shaft, which is very suitable for desert areas.
In Europe, Trina Solar has partnered with developer GP JOULE to support the conversion of 
"brownfield" sites for environmentally friendly use. Building photovoltaic power plants is an 
effective way to renovate and reuse sites. Using Trina Solar's Vertex modules makes a more 
positive contribution to energy transition and climate protection. Trina Solar's 210 Vertex 
modules combine advanced technologies such as non-destructive cutting, multiple main 
grids, and high-density packaging, and have the advantages of high power, high efficiency, 
high power generation, and high reliability, as well as excellent low irradiation performance, 
which can achieve excellent power generation gain and further reduce the cost of electricity 
consumption when combined with the characteristics of local cloudy weather.

TrinaStorage Elementa signs up for UK energy storage project with new 
energy storage battery cabinet
Trina Solar Shines in the Middle East, Boosting Sino-Arab Clean Energy Cooperation
In December 2022, TrinaStorage announced that its previously released high-capacity liquid-
cooled energy storage cabinet product, TrinaStorage Elementa, will be commercially available 
and put into Econergy Renewable Energy's first stand-alone energy storage plant project in 
the UK, the Swangate project. As a leading global provider of energy storage products and 
solutions, Trina Energy Storage will work with G2 Energy to build a 50MW/102MWh capacity 
battery storage project for Yorkshire in Northern England. The system is expected to be grid-
connected in early 2024 and will provide a range of grid-level services to the UK National 
Grid. TrinaStorage Elementa, a new generation of grid-scale liquid-cooled energy storage 
system, has received widespread attention from overseas markets, and signed projects have 
exceeded 500MWh.
TrinaStorage focuses on the new power system, gives full play to the advantages of PV 
storage integration, and takes TrinaCore as its core competitiveness to actively lay out the 
global market and achieve the annual shipment of around 2GWh in 2022.
Chinese President Xi Jinping went to Saudi Arabia to attend the first China-Arab States 
Summit in Riyadh from December 7 to 10, 2022, and proposed that "as the first follow-up 
step to building a China-Arab community with a shared future and implementing the Outline 
of the Comprehensive Cooperation Plan Between China and Arab States, China will, in the 
next three to five years, work with the Arab side to advance cooperation in eight major 
sectors." Among them, "green innovation" and "energy security" are two important elements 
of the "Eight Major Cooperations".
Over the years, Trina Solar has actively contributed to the Sino-Arab clean energy 
cooperation. In April 2022, 44MW of Trina Solar's "210mm N-type 690W" Vertex Series 
modules were shipped to Jubail, Saudi Arabia, to provide green energy for the city's 
independent seawater desalination project. As of the end of the Reporting Period, Trina 
Solar's cumulative PV module shipments in the Middle East and North Africa exceeded 2.3GW 
by project location, equivalent to the production of 3,105 million kWh of clean electricity.

Compliance
Trina Solar adheres to a "zero tolerance" attitude toward all violations of business ethics, 
makes every effort to establish an internal management system and a monitoring and 
reporting mechanism, continuously improves its compliance management system, regularly 
conducts compliance education and training for all employees, vigorously promotes a culture 
of integrity, and severely prosecutes corruption in all business activities.
Trina Solar strictly abides by the laws and regulations related to business ethics in its 
operating locations, and also formulates and strictly implements compliance management 
systems such as the Code of Business Conduct and Ethics, the Anti-Monopoly Compliance 
Policy, the Anti-Corruption Management System Policy, and the Company Reporting Rewards 
Management Measures. We emphasize the principle of "zero tolerance" for business ethics 
and anti-corruption, and carry out business ethics management from multiple dimensions. At 
the same time, we have established clear regulations for all employees and contract workers 
of the Company establishing how to interact with contractors, suppliers, customers, and 
third-party partners involving corruption, conflicts of interest, gifts, and gratuities, and the 
use and protection of the Company's assets.
Trina Solar is committed to establishing a long-term and standardized audit supervision 
mechanism. An Audit Committee was established under the Board of Directors and an 
Internal Audit Department was also set up. In order to ensure the robustness and efficiency 
of the Company's internal control and internal risk management system, the Company has 
established an internal oversight system in which audit and supervision, internal control, 
compliance, and legal affairs collaborate with each other, and the system is responsible for 
the Company's disciplinary inspection, supervision, audit, and internal control evaluation. 
Based on the China Internal Auditing Standards, We follow the provisions of the Basic 
Standard for Enterprise Internal Control and its accompanying guidelines and other internal 
control regulatory requirements; annually, the Company assesses whether internal control 
compliance in the Company's key management activities, such as corporate organization 
management, strategic management, social responsibility management, asset management, 
capital activities, procurement business management, sales business management, 
financial reporting management, human resources management, and information system 
management, is operating effectively, and an audit report is issued by a third-party auditor, 
in order to promote the establishment and improvement of the internal control system, 
improve management and avoid business risks. In 2022, the Company engaged an external 
organization to conduct an internal control audit, and no significant deficiencies in internal 
control were identified.
Business Ethics and Anti-Corruption
Trina Solar upholds the business ethics of honesty, compliance,and 
fair competition, and is committed to establishing a professional 
and industry-leading business ethics compliance system, building 
a sustainable ethical business culture of integrity, and ensuring the 
highest ethical standards in our interactions with all stakeholders.
Supplier Anti-Corruption Management
Through the Trina Solar Supplier Code of Conduct, the Social Responsibility Management 
Code and the Supplier Management System, Trina Solar conducts anti-corruption 
management for suppliers in three aspects: management requirements, assessment and 
supervision, and training and incentives.
In 2022, based on our supplier compliance training program, we conducted compliance 
training for suppliers on anti-corruption and anti-bribery. We introduced Trina Solar's 
compliance management philosophy and compliance requirements to suppliers, emphasized 
the main items to pay attention to in the procurement process, introduced in detail the 
concept of conflict of interest and related legal backchannels, and explained the ways to 
report violations.
Case
In terms of external audits, Trina Solar engages third-party representatives to provide services for or on behalf of the 
Company in the course of its business. In 2022, the designated third party conducted an independent external audit 
of the Company in accordance with the provisions of applicable laws and regulations and regulatory requirements, and 
issued relevant reports in accordance with the regulatory timeline.
Trina Solar has established and strictly implemented a compliance training system, with compliance training programs and 
courses developed by relevant departments.
All employees must receive regular compliance training from the time they join the Company, and the effectiveness of 
the training will be tested by examinations. Board members, full- and part-time employees, and employees of outsourced 
contractors are all required to attend anti-corruption and business ethics training on a regular basis. We also develop 
additional training programs for key business units to increase the frequency of training.
In addition, The Company has a series of management mechanisms to reasonably ensure the company's compliance 
and legal operations, including: the Company strictly complies with the regulatory requirements of various domestic 
and foreign financial institutions in key business processes that involve the receipt and payment of funds, such as sales 
business, procurement business, fund management and investment management, making efforts to guarantee the 
operational effectiveness of the anti-money laundering internal control mechanism.

Product Lifecycle Green Management
Since its establishment 25 years ago, Trina Solar has been both a producer of green energy and a 
practitioner of green development. We not only produce clean electricity through photovoltaic modules, 
but also contribute to the transition to green and low-carbon manufacturing.
Trina Solar has always attached great importance to carbon emission control in all aspects of the 
module's life cycle. In the low-carbon design process, we systematically consider the impact on 
resources and the environment in the selection, production, distribution, use, recycling, and disposal 
of raw materials, and strive to use as many harmless raw materials as possible to achieve a green and 
low-carbon development. In 2022, Trina Solar received a national certification as an "Industrial Product 
Green Design Demonstration Enterprise". In addition, in 2021, we received the world's first mutual 
recognition marks from UL Solutions and Environmental Product Declaration (EPD) in the PV industry. 
During the Reporting Period, Trina Solar's full series of 210 Vertex modules received the Life Cycle 
Assessment (LCA) certification for PV modules from TÜV Rheinland, making us the first PV company to 
complete the generic LCA certification for 210 PV modules.
Trina Solar supports and practices material recycling, and actively works with upstream and 
downstream suppliers to track and recycle packaging materials of products.
Trina Solar's packaging material recycling categories include cartons, cardboard, wood boards, plastic 
tubes, welded tape turnaround packages,  cell turnaround packages, glass and iron pallets, etc. We have 
established and implemented a production-warehouse-purchase integrated package recycling process. 
In the production process, we carefully sort and pack the recycled packages; in the procurement 
process, we contact the recycling suppliers according to the production and transportation situation 
to improve the efficiency of package recycling; in the warehouse process, we follow the internal 
"Packaging Material Recycling Operation Guideline" and register the information and quantity of 
products to be recycled and the actual package recycling ledger daily.  
In 2022, our package recycling rate was approximately 80%.

Trina Solar's Full Series of 210 Vertex Modules Received LCA Certification for 
Full Lifecycle Low-carbon Management
The Life Cycle Assessment is based on the life cycle assessment methods and requirements 
of ISO 14040/ISO 14044, and is a scientific and rigorous test of the evaluation targets. Based 
on the LCA, Trina Solar has conducted a comprehensive analysis of more than ten indicators 
that affect the global ecological environment, including energy consumption, raw material 
consumption, acid rain, eutrophication, environmental toxins, waste, and other thousands of 
substances collected from the Vertex modules.
During the Reporting Period, Trina Solar's products submitted for testing and approval 
covered the full series of monocrystalline P-type 210 size PV modules from the Vertex S 
410W to the Vertex 670W; the manufacturing factories include all major production bases 
around the world. Trina Solar's Vertex series modules have the lowest carbon emissions 
per unit (per watt) in the industry during the manufacturing process. The average carbon 
emission of domestic PV modules is over 550g per watt, while the carbon emission of Trina 
Solar 210 Vertex modules is within 400g per watt without the use of special silicon materials, 
which is more than 30% lower than the domestic average.  Taking the 30-year product life 
cycle as an example, Trina Solar Vertex Series modules have an emission factor of less than 
0.01 kWh.

Trina Solar Co., Ltd. Sustainability Report 2022
In 2022, while complying with our Environmental Aspect Identification and Evaluation Procedure, we 
adopted the Aqueduct Water Risk Atlas from the World Resources Institute (WRI) to evaluate water risk 
levels in areas where our 12 factories are located.
According to the results, our ten domestic factories were 100% rated medium-to-low risk or low risk. 
Our factory in Thailand was rated medium-to-high risk. Our factory in Vietnam was rated high risk.
To reduce our dependence on local water resources, our factories in Thailand and Vietnam actively 
improve the water recycling rate through multiple measures such as collection and reutilization of 
water, wastewater regeneration, etc. No incidents affecting production due to water shortage have 
occurred in our operations so far.
Our EHS committee conducts monthly statistics and analysis of water consumption and water pollutant 
discharge monitoring data to ensure the implementation progress of water consumption targets. Also, 
it checks potential abnormal water consumption to ensure that the water consumption of the Company 
meets water consumption control targets and that the wastewater meets the local water pollutant 
discharge standards before discharge.
Our water sources mainly include municipal water. Through equipment modification, technology 
upgrading, reclaimed water reuse and other measures, our factories maximize water efficiency in 
production and operation. In 2022, our total water consumption was 14,449,496 tons, of which 
production water accounted for approximately 96%. Our water consumption intensity per unit of cell 
product was 384.89 tons/MW, a decrease of 62.72% from the base year, and water consumption 
intensity per unit of module product was 39.83 tons/MW, a decrease of 53.20% from the base year. As

We classified wastewater into industrial wastewater and domestic sewage and took corresponding 
measures for treatment. We made full use of wastewater that could be recycled, and treated 
wastewater that could not be recycled to meet corresponding standards before discharge. Domestic 
sewage was discharged via the municipal sewer networks for treatment. We monitor the discharge of 
wastewater regularly. In 2022, we further collected and analysed the total amount of wastewater and 
made a detailed breakdown of our wastewater-relevant pollutants.
The wastewater disposal measure "rainwater and sewage separation system" we designed was used 
to separate rainwater from the sewer networks, which prevents possible fire wastewater and chemical 
waste liquid from directly discharging to the rainwater networks. To reduce water pollutants, we 
actively upgrade our cleantech, which enables high utilization efficiency of raw materials and lessens 
discharge of pollutants. Also, we strictly strengthen our control over the discharge of wastewater and 
update the list of water pollutants at least once a year.

Sustainable Construction of Qinghai Crystal & Silicon production base
In 2022, we invested the 35GW monocrystalline Czochralski (CZ) Project in Nanchuan Industrial 
Park in the Xining Economic and Technological Development Zone, Qinghai, to achieve win-win 
situations of local economic development and enterprise development. The project complies with 
the planning requirements of Nanchuan Industrial Park, Xining, and obtained the environmental 
impact assessment report issued by a third-party institution in September 2022.
The premise of our factory lays out on a planar slope. Each functional domain in the factory is 
relatively independent, but also closely combined, which forms an organic whole. The project site 
is crossed by the Xiamen Gorge River, so we designed a green landscape within 10 meters of both 
sides of the river without polluting facilities. The shortest distance between the buildings along 
the riverway and the river is equal to the distance between the solid waste warehouse and the 
river, which is 16 meters.
In addition, we set a certain area of green belt around the factory. Transporting equipment for raw 
materials and finished products and noisy equipment are all arranged indoors.

Continuous Reduction of Hazardous Waste Production and 
Emission Through Optimized Design
In our module workshops, silica gel and AB gel are used in the framing process. The packaging 
drums and waste gel used to be disposed of as hazardous waste, resulting in large amounts 
of hazardous waste.
In 2022, we implemented the following measures to reduce hazardous waste:
 Tinfoil is added inside the silica gel vat for gluing on the frame. Then the tinfoil dipped in 
gel is taken out and disposed of as hazardous waste, while the clean silica gel vat can be 
recycled as recyclable waste.
 We use 5-gallon-plastic drums for the bottom glue of the original wiring box. The drums 
are also disposed of as hazardous waste. During the Reporting Period, we replaced the 
5-gallon-plastic drums with large iron drums to increase the piping to the bottom glue when 
we revamped the workshops.
 The residue of silica gel in iron drums is used as much as possible. The wasted silica gel 
is monitored by weighing the residue to ensure that the quantity of waste is maintained 
below 10kg each time.

no relevant data had been collected for the year.
12.The increase in sulfoxide in 2022 was mainly driven by the fact that the Vietnam Taiyuan production base, which 
manufactures our cells, began recording sulfoxide emissions for the first time in 2022.
Exhaust Gas Management
Our exhaust gas mainly consists of greenhouse gases, particulate matter, and nitrogen oxides from the use of purchased 
electricity and combustion of natural gas. We continuously improve the management of exhaust gas emissions. In 2022, 
the exhaust gas sensing device installed in the Yiwu production base effectively monitored exhaust gas emissions online, 
ensuring that the exhaust gas was treated before emission to reduce the risk and adverse effects of non-compliance 
with environmental standards. In addition, we regularly invite qualified third-party institutions to conduct on-site 
environmental tests and issue test reports.

and considers it an integral part of our business operations and 
practices for sustainable corporate development. Our workplace 
safety system covers full-time, part-time and contractor employees, 
including those whose work or workplace is under our control.
In 2022, Trina Solar further updated the EHS Committee Management System to optimize the work 
contents including a monthly inspection and implementation of rectification programs, employee 
safety training, performance tracking, and employee safety suggestions. In the EHS Responsibility 
Management System, we refined the safety responsibilities of important positions such as the person 
in charge, the EHS person in charge, and the person in charge of the production base. In the meantime, 
we optimized the content of the EHS Accident Investigation Management System during the Reporting 
Period, clarifying that accident reports should be reported to management and emphasizing the 
adoption of different accident reporting processes for accidents of different levels, in order to improve 
the efficiency of accident investigation and analysis and to take timely corrective measures to prevent 
similar incidents from recurring.

management and have all obtained ISO 45001 occupational health and safety management system 
certification. We have established a global safety incident management mechanism that requires all 
factories worldwide to report safety incidents within a specified time frame, submit and take timely 
and targeted corrective and preventive measures for the causes of incidents, and hold responsible 
managers accountable for causing serious accidents to promote a long-term safety production 
management mechanism.
