What is PID (performance induced degradation) of a Solar Panel?

 

This question is part of the Super Big Solar Panel FAQ from Solar Mango, where expert answers to over 100 important questions on solar panels are provided.

 

Potential Induced Degradation (PID) is a degradation of the solar panel caused by voltage, heat and humidity.

If your solar panel is affected by PID, there is a good chance that it will be completely damaged within a few years from the time of installation, and might need to be replaced – a rather costly exercise.

It is possible to minimize or prevent PID through incorporation of effective anti-PID elements in the panels.

This – the presence of anti-PID feature – is one aspect you should check in the panel before you decide to purchase it. Details of this are usually provided in the data sheet. If you cannot find the details, ask the installer/EPC about this.
