Solar Panels Pid Free

Pid phenomenon potential induced degradation is a voltage driven leakage of current between the solar cells and the front glass of a solar panel operating in hot humid environments.

Solar panels pid free.

Sunfuel provides pid free solar power modules. While concerns have been raised around the way in which these panels are tested pid remains a serious problem affecting a number of solar installations. However in practice pid free does not mean no degradation will occur. Potential induced degradation pid is a potential induced performance degradation in crystalline photovoltaic modules caused by so called stray currents this effect may cause power loss of up to 30 percent.

This may mean a cost increase on the solar panel but at least that pid free claim can be supported. What are pid free solar panels. Meydbray said although frameless and glass glass modules claim to be 100 pid free since there s no metal frame to disrupt voltages. We certainly feel that it is worth taking the time to understand what pid is and what you can do to protect your system against its effects.

The cause of the harmful leakage currents besides the structure of the solar cell is the voltage of the individual photovoltaic pv modules to the ground. As new module configurations enter the market installers are still cautioned to be aware of pid issues.
