Chint/Astronergy says its mono- and polycrystalline modules have passed a potential induced degradation (PID) test conducted by TUV Rheinland.
PID is an effect that leads to significant power output decline of PV modules under the condition of negative bias voltage, high temperature and increased humidity. During the test, PV modules from Astronergy were assessed after being exposed to -1000 V at a temperature of 85 degrees C and relative humidity of 85% for 96 hours.
Astronergy's PV modules exhibited less than 1.4% degradation result, which is below the TUV standard of not exceeding 5%, the company says.
