Annex 2

Limited Warranty for PV Modules

for PV Modules sold to IBC

1. Limited Product Warranty  Five Years Repair, Replacement or Refund Remedy (for deliveries in 2007 the period will be 2 years)

Subject to Clause 3 below, Changzhou Trina Solar Energy Co., Ltd (TRINA) warrants its Photovoltaic Solar Modules, including factory-assembled DC
connectors and cables, if any (together, the MODULES), to be free from defect in materials and workmanship under normal application, installation, use and service conditions, for a period ending sixty (60) months from the date of
sale as shown on the invoice to the original end customer (the CUSTOMER). If MODULES fail to conform to this warranty during such sixty (60) month period, TRINA will, at its option, either repair or replace the product, or refund
the purchase price as paid by the CUSTOMER. Such repair, replacement or refund shall be the sole and exclusive remedy provided under this Clause 1 and shall not extend beyond the sixty (60) month period set forth herein. It will be performed
directly to the CUSTOMER only. This Clause 1 does not warrant a specific power output, which shall be exclusively covered under Clause 2 below (Limited Peak Power Warranty). According to the valid laws in Germany and the European Union,
in case of any defect of the Modules within the first 24 months from the date of sale as shown on the invoice to the original end consumer, TRINA will bear supplementary to the above described liability all other cost to handle the warranty, such as
cost for evaluation, transport, deinstallation, reinstallation and missing energy production.

2. Limited Peak Power Warranty  Limited Remedy

12 years (for deliveries in 2007 the period will be 10 years)

Subject to Clause 3 below, if, within a period of twelve (12) years (10 years for deliveries in 2007) from the date of sale as shown in the invoice to the CUSTOMER, any MODULE(s) exhibits a power output less than 90% of the
Peak Power at STC as specified at the date of invoice in TRINAs applicable product information sheet (the PRODUCT INFORMATION SHEET), TRINA will, at its option, either provide additional MODULES to the CUSTOMER to make
up for such loss in power, or replace the defective MODULE(s).

25 years

Subject to Clause 3 below, if, within a period of twenty-five (25) years from the date of sale as shown in the invoice to the CUSTOMER, any MODULE(s) exhibits a power output of less than 80% of the Peak
Power at STC as specified at the date of invoice in TRINAs PRODUCT INFORMATION SHEET, TRINA will, at its option, either provide additional MODULES to the CUSTOMER to make up for such loss in power, or replace the defective MODULE(s).

---

The remedies set forth in this Clause 2 shall be the sole and exclusive remedies with respect to any deficiency in the
power output of MODULES.

Peak Power at STC

Peak Power at STC is the power in Watt peak that a PV-module generates in its Maximum Power Point. STC
(Standards-Test-Conditions) are as follows: (a) light spectrum of AM 1.5, (b) an irradiation of 1.000W per m2and (c) a cell
temperature of 25 degree centigrade at right angle irradiation. The measurements are carried out in accordance with IEC 61215:2005 as tested at the connectors per calibration and testing standards according to IEC 60904-1 ...... IEC 60904-10.
