Both multicrystalline and monocrystalline PV modules from JA Solar have passed normal potential induced degradation (PID) tests conducted by TÜV SÜD.
The modules tested were found to have demonstrated less than 1% power degradation after experiencing temperatures of 85 degrees Celsius, 85% relative humidity, and 1,000 volts of system bias voltage, for a duration of 96 hours. Normal PID testing allows for up to a 5% power loss to have passed the test.
