ReneSola Becomes First PV Solar Company in China to be Certified for TUV SUD PID Testing

ReneSola Ltd. (“ReneSola” or the “Company”) (NYSE: SOL), a leading brand and technology provider of solar photovoltaic (“PV”) products, today announced its ReneSola Jiangsu Product Center Laboratory has successfully completed an audit performed by TUV SUD, one of the world’s leading providers of testing and certification services. The audit certifies that the Company’s laboratory is qualified for potential induced degradation (PID) testing on photovoltaic modules according to International Electrotechnical Commission standards.

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

Dr. Bill Hou, ReneSola’s product center director, said, “PID is a very important issue and can cause a significant decrease in power generation. ReneSola has always aimed to produce PID-free modules and is leading the industry by 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. Moreover, I am pleased that we are the first lab center in China to receive such recognition. Now we will be able to perform onsite PID tests to obtain TUV SUD accreditation, and we will continue to work with other well-known accreditation organizations to ensure top performance in all aspects of our solar testing.”
