Trina Solar Announces Achieves Anti-PID Ability for all Self-Produced Solar PV Cells

Anti-PID Solar PV Cells that Conform to IEC62804 Ed.1.0 (82/685/NP) Standards to be Used in Module Manufacturing

CHANGZHOU, China, March 25, 2014 -- Trina Solar Limited (NYSE: TSL) ("Trina Solar" or the "Company"), a global leader in photovoltaic ("PV") modules, solutions, and services, today announced that all solar PV cells produced by the Company have achieved anti-PID (Potential-Induced Degradation) ability following the optimization of the Company's manufacturing technology.

From April 2014, all Trina Solar modules using the Company's self-produced cells will conform to IEC62804 Ed.1.0 (82/685/NP) standards, a system voltage durability testing standard (commonly known as the PID Test). Trina Solar will also be able to produce modules to meet stricter PID testing criteria based on customers' needs. Additionally, the Company's PV modules, which use anti-PID solar PV cells, have been successfully certified by TUV SUD.

"Trina Solar is committed to providing our customers with products that offer the highest standards of performance," commented Mr. Zhiguo Zhu, President of Trina Solar's Module Business Unit. "Achieving anti-PID ability in all cells we produce is a significant milestone for our Company and demonstrates our commitment to continuous optimization of our manufacturing technology and implementation of the strictest standards in product quality management."

By optimizing cell and the module manufacture technology, our anti-PID modules can effectively reduce loss in power output from solar panels due to induced degradation, as well as that caused by severe conditions including high voltage, severe salt mist and high humidity such as that common in coastal area.
