SHANGHAI, January 23, 2013--JA Solar Holdings Co., Ltd., (NASDAQ: JASO) ("JA Solar" or the "Company"), one of the world's largest manufacturers of high-performance solar power products, today announced that its multicrystalline and monocrystalline PV modules successfully passed Potential Induced Degradation (PID) tests conducted by TÜV SÜD, one of the world's leading providers of testing and certification services.
JA Solar's modules were tested under extreme conditions, including temperatures of 85 degrees Celsius, 85% relative humidity, and 1,000 volts of system bias voltage, for a duration of 96 hours. Test results showed less than 1% power degradation in the modules.
The solid performance of JA Solar's modules stems from the Company's adoption of PID resistant solar cells in the module-manufacturing process. The PID resistant cells significantly decrease undesired power loss caused by high system voltages, lengthen the lifespan of modules, and ensure stable operation in adverse weather conditions.
"The strong performance of our modules in TÜV SÜD's PID tests represents another milestone in JA Solar's efforts to produce industry-leading products with superior stability," said Mr.Yong Liu, CTO of JA Solar. "Customers value JA Solar for the reliability and efficiency of our product offering, and our persistent focus on technological innovation ensures that we meet and exceed their high expectations."
