Trina Solar Awarded Underwriter Laboratories' CTDP Certification

Trina Solar's Changzhou PV Testing Center is now eligible to participate in the Client Test Data Program after undergoing a rigorous inspection and audit by Underwriters Laboratories

CHANGZHOU, China, Nov. 15, 2012 /PRNewswire/ -- Trina Solar Limited (NYSE: TSL) ("Trina Solar" or the "Company"), a leading integrated manufacturer of solar photovoltaic (PV) products, today announced that it has obtained the Client Test Data Program ("CTDP") certification from UL (Underwriters Laboratories). The Company is the first solar PV company to be awarded this certification, reflecting Trina Solar's continued commitment to its PV testing capabilities and its emphasis on product quality and reliability.

Trina Solar's Changzhou PV Testing Center is now eligible to participate in the Client Test Data Program after undergoing a rigorous inspection and audit by UL. As the first CTDP-certified PV company, Trina Solar goes one step beyond the Witness Test Data Program ("WTDP"). Trina Solar is now able to independently conduct testing programs and to issue UL recognized test data without requiring the on-site presence of UL dispatched engineers.

In conjunction with the certification, UL and Trina Solar have signed a framework agreement to strengthen collaboration.

"Trina Solar's collaboration with UL will further the quality and reliability of our products," commented Mr. Zhiguo Zhu, SVP and President of Trina Solar's Module Business Unit. "Being the first PV company to receive the CTDP certification is an important milestone in the development of Trina Solar. It affirms that our testing staff, standards and capabilities are of the highest caliber in the PV industry."

Mr. Zhu added, "The certification and collaboration also highlight Trina Solar's commitment to research and development and product excellence, which are key to solidifying our Company's brand in the U.S. and other global markets. In order to overcome the challenges we face in the global PV industry today, Trina Solar is working tirelessly to improve the overall value of its PV products and the affordability of solar-generated electricity."

"We are pleased to have awarded the CTDP certification to Trina Solar. Dedicated efforts from both sides allowed the review and certification to be accomplished in a relatively short period. During the entire process, we were very impressed by the professional and technical qualities that Trina Solar's staff demonstrated," commented Mr. Jun Shi, Deputy General Manager of UL China. "By signing this collaboration with Trina Solar, we look forward to continuing to work together in advancing safety and quality standards in the PV industry."

Encompassing a total area of ??over 7000 square meters, Trina Solar's Testing Center supports product certification, material reliability testing, highly accelerated aging test, and a comprehensive range of test material evaluation and research. Testing capabilities cover PV product testing standards including IEC61215, IEC61730 and UL1703. These tests simulate stresses in the natural environment and examine the ability of PV products to withstand and maintain performance in the extreme weather conditions, which they are subject to.
