Major Korean PV module manufacturer, SolarPark Korea has had two 60 cell mono-crystalline and three multi-crystalline modules pass the Potential Induced Degradation (PID) test, conducted at Photovoltaic Institute Berlin (PI Berlin) and certified by TÜV-SUD.
PI Berlin exposed the modules to 1,000 volts of bias voltage for 96 hours at a temperature of 60°C and relative humidity of 85%, resulting in a ‘Quality Categorization A’ indicating a measurement of less than 0.1% power output degradation.
“Knowing that this test was becoming an important issue, our quality lab conducted several internal PID tests on modules to ensure good results,” noted Hyunwoo Park, CEO of SolarPark Korea. “Our modules were able to achieve this through our 100% automated production, which only leaves room for perfection and consistent high quality. Customers know that we stand by our quality and that we are reliable.”
