The potential induced degradation (PID) is addressed with the standard IEC TS 62804-1. The standard defines two methods that enable analyzing occurring PID effects in a specific PV module type.
PSE AG offers the necessary equipment for the test in a climate chamber.
The test equipment can work with any climate chamber on the market and is delivered turnkey. It comes with all necessary equipment, high voltage power sources, sensors, data acquisition and software.
As the high voltage sources can supply negative and positive, it is also possible to anneal solar PV modules that show potential induced degradation effects.
An electrical isolated rack for the installation of the PV module inside the climatic chamber and a UPS (uninterruptable power supply) to continue the measurements during electrical break down can optionally be ordered with the equipment.
