JinkoSolar Modules Pass PID Test at 65 Degrees Celsius

JinkoSolar Holding Co., Ltd. (“JinkoSolar” or the “Company”) (NYSE: JKS), a leading global solar power product manufacturer, today announced that the Company’s modules passed potential induced degradation (PID) testing conducted by TUV-SUD and the Canadian Standards Association(CSA).

During the testing period, solar modules were exposed to 1,000 volts of negative socket voltage under the condition of 65 degrees Celsius/85% relative humidity. In order to pass this extreme test, the maximum degradation of power output between initial and final measurement should not exceed 5%. Tested Jinko modules have successfully passed the stringent requirements set by TUV-SUD and the CSA to be PID resistant.

While being exposed to hot and humid conditions, hundreds of volts can accumulate between the solar cell and the module frame affecting the power output of the entire solar system. This can lead to potential induced degradation (PID) in a module, resulting in power losses of up to 50%. The PID test conducted by TUV-SUD and the CSA underscores the importance of being PID certified and the effect it has on the life of JinkoSolar products.

“JinkoSolar has become one of the few companies with modules that have successfully passed TUV-SUD and the CSA’s high-level tests under the condition of 65 degrees Celsius/85% relative humidity. I am very delighted to see this happen since it is a manifestation of the relentless efforts of all Jinko employees,” said Kangping Chen, CEO of JinkoSolar.

“Our customers are increasingly aware of the importance PID plays in the quality of solar modules. PID resistance not only ensures a high power output, but also improves the safety of our solar modules. This is another demonstration of JinkoSolar’s high product quality and reliability, especially under extreme outdoor conditions,” JinkoSolar’s Chief Marketing Officer Arturo Herrero added.
