Centrosolar has received the best possible potential induced degradation (PID) test results for its range of photovoltaic modules. The test monitors one of the main causes of reduced performance of photovoltaic modules over their lifecycle.
Centrosolar commissioned the testing institute TÜV Rheinland to perform the analysis. During the test, modules are subjected to a negative voltage of 1,000 volts for seven days. To pass the test the modules performance must not reduce by more than five percent. Following that, the modules are then tested at fluctuating temperatures for a further seven days.
During the PID test, Centrosolar modules performance reduced by less than one percent. The results confirm that modules produced by Centrosolar should perform consistently over decades.
Dr Johannes Kneip, Managing Director of Centrosolar AG, said: “The outstanding results of the PID test are just another indication of the high quality of our modules. We examine cells and modules in our production facility according to the same standards as TÜV. We only deliver systems that are guaranteed to be PID-free.”
