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 volts of bias voltage at a temperature of 85 degrees Celsius 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%.

Mr. Xianshou Li, ReneSola's chief executive officer, commented, "The fact that our high-wattage 300 W poly module passed TUV SUD's PID test by such a large margin underscores its value proposition. Solar developers not only get more power per square foot with this module, but also a long life cycle with minimal degradation and reliable power output. PID is an important purchasing factor for solar developers,
