ReneSola Ltd. says its 300 W multicrystalline solar module has passed the potential induced degradation (PID) test performed by TUV SUD, a provider of testing, inspection and certification solutions.
The PID test was conducted by TUV SUD to assess loss of power output of solar modules under severe conditions of high voltage, high temperature and high humidity. ReneSola's 300 W multicrystalline solar module was exposed to 1,000 V of bias voltage at a temperature of 85 degrees C and a relative humidity of 85% for 96 consecutive hours.
During the test, ReneSola's maximum degradation of power output was 1.34%, significantly below the maximum allowable power output degradation of 5%, the company says.
