Germany-based Centrosolar AG says that testing agency TUV Rheinland has certified that its modules are resistant to voltage-related performance degradation.

This effect, which is referred to as potential induced degradation (PID), is one of the main causes of reduced performance of photovoltaic modules over the course of their life cycle. During TUV Rheinland's test, the modules are subjected to a negative voltage of 1,000 volts for seven days at room temperature. The test qualifies as passed once the performance of the modules is reduced by no more than 5%.

The Centrosolar modules showed performance reduction of less than 1%, the company says.
