SolarWorld quality ensures long-term high performance and stability

PID-free label for SolarWorld modules

The independent solar module test laboratory PV Evolution Labs (PVEL) in Berkeley, California, has awarded solar power modules from the SolarWorld AG the highest level certification: free from Potential Induced Degradation (PID-free). With this, the laboratory certifies products from the German solar energy group as possessing high quality and lasting performance.

In principle, there is always a difference in electrical potential between the frame and solar cells. Low-grade materials, susceptible solar cells, and a warm and humid climate – combined with this difference in potential – can lead to a significant reduction in output, known as Potential Induced Degradation (PID).

The goal of the test is to determine the stability of SolarWorld modules in regard to PID. PVEL compares module performance after a stress test with the original performance. During the 600-hour test in an extremely warm and humid climate (85°C/85% humidity), very high voltages of +1000 V or -1000 V exist between solar cell and frame. PVEL engineers determined that SolarWorld modules performed far better than the allowable degradation limit.

"With this test result and certification by PVEL, SolarWorld modules have proven their ability to deliver high performance over a long period of time," said SolarWorld Chairman and CEO Dr.-Ing. E. h. Frank Asbeck. "This is an additional investment safeguard for our customers and investors."
