Both multicrystalline and monocrystalline modules from Canadian Solar have passed the Fraunhofer ISE's PID test in accordance with the draft IEC62804 (System Voltage Durability Qualification Test for Crystalline Silicon Modules).
The major PVEP (PV energy provider) said it was the third consecutive year its modules had passed PID testing.
Canadian Solar noted that its CS6P-P series (60 cell, polycrystalline) and its monocrystalline MWT (Metal Wrap Through) cell modules, ELPS CS6P-MM series (60 MWT cell, monocrystalline) passed the testing regime for potential induced degradation.
The company did not reveal power degradations for the various modules, which must be below 5% to pass.
Fraunhofer ISE's PID test includes chamber air temperature pf 60 degrees Celsius +/- 2 degrees Celsius and a chamber relative humidity of 85% +/- 5% RH. The test duration was 96 hours and the standard -1000V voltage.
