What is a photovoltaic PID module
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. 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. In most ungrounded P. HistoryThe term "potential-induced degradation" (PID) was first introduced in the English language in a published study by S. Pingel and coworkers in 2010.
