The occurrence of leakage current that can occur in photovoltaic (PV) system depends strongly on the value of parasitic capacitance between PV panel and the ground.

How does leakage current affect a PV system? The leakage current in a PV system is represented by the insulation resistance of the PV string. The decline in the fill factor eventually decreases the

If PV panels have any leakage resistance between their PV wires and frame of PV panels you will get some leakage from AC square wave. In a salty air environment this may happen.
