Upsolar, a provider of solar PV modules, says its product portfolio has demonstrated "exceptional" resistance to potential induced degradation (PID), according to specifications set forth by the International Electrotechnical Commission (IEC).

Testing conducted by the Institute of Industrial Certification for Mechanics (ICIM), an independent certification body based in Italy, yielded minimal performance impact under extreme conditions.

Designed to analyze module performance after extended use, PID evaluation subjects PV modules to high humidity, elevated temperature levels and voltage stresses. After an evaluation period, products are assessed in terms of output and durability. Electroluminescence imaging is also performed to identify defects with potentially negative impact on module performance.

Upsolar modules were PID-tested under IEC 62804 Ed. 1.0 specifications. The products' performances significantly exceeded the threshold set forth by IEC parameters, passing the test by a wide margin, according to the company.
