Renesola qualified for PID testing on PV modules

ReneSola Jiangsu Product Center Laboratory is qualified for potential induced degradation (PID) testing on photovoltaic modules according to International Electrotechnical Commission standards.

The certification follows an audit performed by TUV SUD.

The ReneSola Jiangsu Product Center Laboratory is the first lab in China to receive the TUV SUD accreditation for PID testing. ReneSola mono-crystalline and high-efficiency polycrystalline (Virtus II) solar panels regularly undergo the rigorous PID testing process, the company said.

The tests are designed to evaluate the loss of power output of solar panels under severe conditions of high voltage, high temperature and high humidity.


Bill Hou, ReneSola’s product center director, says PID is a very important issue and can cause a significant decrease in power generation. ReneSola has focused on producing PID-free modules and optimizing both the solar cells and the encapsulation materials of our panels.

Our lab team has done an excellent job in obtaining this accreditation, which signifies our ability to conduct reliable and quality testing of solar panels.

With these tests, ReneSola is able to perform onsite PID tests to obtain TUV SUD accreditation. The company will continue to work with other well-known accreditation organizations to ensure top performance in all aspects of our solar testing.
