Abstract—In the photovoltaic (PV) plant, the parasitic capacitance between the PV panel and the ground (CPV) causes leakage current in the non-isolated systems. The case can be deteriorated in the rainy

The fluctuating voltage constantly changes the charge state of the parasitic PV capacitor (i.e. capacitance to PE). This is associated with a displacement current, which is proportional to the

Thus, this paper gives complete parasitic capacitance model of the PV panel considering the rain water. The effect of the water on the capacitance is systematically investigated through 3D finite element

Indeed, you have no capacitance between case and ground to take into account as they must be connected for equipotentiality reasons (important against lightning).
