How to detect PID on your PV plant?

Drone inspectieCharacteristic for PV plants is that they will underperform as a result of Potential Induced Degradation or PID. This phenomenon occurs on all types of PV plants, often without the owner of the installation being aware of it. PID implies that solar modules are subjected to accelerated efficiency losses and therefore don't achieve the expected [...]

How to detect the presence of PID?

Infrarood test

Potential Induced Degradation (PID) is the main reason for efficiency losses of solar panels. Therefore it is important to timely detect this phenomenon. The presence of PID can be detected by means of several tests. 1. Electroluminescence test An electroluminescence test is done at night with a charge-coupled device camera, while the module is energized by […]
