JinkoSolar Holding Co. Ltd., a solar power product manufacturer, says its solar modules have 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 V of negative socket voltage under the condition of 65 degrees C and 85% relative humidity. In order for the modules to pass this test, the maximum degradation of power output between initial and final measurement could not exceed 5%.
Tested Jinko modules have successfully passed the requirements set by TUV-SUD and the CSA to be PID-resistant, the company says.
