Parasitic

Parasitic capacitance of photovoltaic panels

Leakage current, also referred to as matrix residual current, arises from parasitic capacitance between the photovoltaic (PV) system and the ground. This phenomenon occurs when the PV system lacks a transformer, forming a low-impedance loop with the power grid. This capacitance is not required for the function of the PV array, but comes about essentially from the mechanical structure of the modules and their installation, and is therefore also known as. . Parasitic capacitance in solar PV modules By their design, all solar PV modules will have an electrical capacitance in relation to their environment. The case can be deteriorated in the rainy environment because the CPV increases dramatically due to the rainwater.
