ReneSola Ltd today announced its 300 watt ("W") multicrystalline solar module has passed the potential-induced degradation ("PID") test performed by TUV SUD.
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, particularly if the modules are to be used in areas of high humidity and high temperatures. Our TUV SUD test result should reassure customers of the reliability of our solar modules and demonstrate our commitment to producing high-quality solar products."
