Abstract: 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. However, traditional method to acquire that value is by experience estimation.
The capacitor represents the accumulation of charges in the PV device. The capacitance of a PV device is attributed to both junction capacitance and diffusion capacitance, both of which are voltage dependent.
The effect of solar cell capacitance in the electrical characterization of photovoltaic (PV) modules at Standard Test Conditions (STC) is known since the 1990s.
However, the proposed model is only for the PV panels under dry and clean environmental conditions. The dependence of rain water on the capacitance is simply described rather than analyzing in detail. Furthermore, the effects of water are addressed quite differently in papers.
ABSTRACT: Considering the structure of PV systems, a stray capacitance can appear between the PV arrays and the ground. When transformerless inverters are used, this capacitance can cause leakage currents to the ground.
The capacitance of a PV device is attributed to both junction capacitance and diffusion capacitance, both of which are voltage dependent. Junction capacitance represents charge storage in the depletion region of the diode and is more observed at low voltages (at cell level, for c-Si: from ∼ 0 to 0.3 V).
