Trina Solar will supply approximately 320,000 TSM-PC05A modules with power outputs of 245 Wp, 250Wp and 255 Wp. All modules are of the highest anti-PID level currently available – up to 85°C / 85% relative humidity. In addition, all modules come with a 25-year linear power output performance guarantee. Module shipments are expected to be completed by the end of 2014.
Based on the way conventional photovoltaic systems work, voltage differences occur between the frames and the solar cells of a module. Especially in wet weather this can lead to undesired leakage currents which can decrease the performance of the cells. According to a report by the industry journal Photon (12 / 2010), this can result in yield losses of 20 % or more. This effect has been named “Potential Induced Degradation”, abbreviated “PID”.
“We are very proud to have secured this contract and to supply our advanced anti-PID modules to this unique project, which is one of the first few large-scale power plants designed to an 85°C / 85% relative humidity anti-PID standard,” said Zhiguo Zhu, President of the Module Business Unit of Trina Solar. “This once again showcases our ability to produce the very best solar products and to continue to meet our customer’s evolving needs. Trina Solar remains deeply committed to product innovation and we continue to integrate R&D successes into our solar products. Our focus remains on enhancing product performance, reducing costs and delivering both commercial and financial benefits to our customers.”
By optimizing cell and module manufacturing technologies, Trina Solar’s anti-PID modules effectively reduce the loss in solar panel power output caused by severe environmental conditions including high voltage, severe salt mist and high humidity.
