Abstract

Photovoltaic (PV) array, which is generally installed outside, has the possibility of being damaged by high voltage due to lightning. primarily because the electrical characteristics of PV array have not been fully identified by lightning yet, there is a very important issue whether PV array should be connected with a ground or not. In this paper, a basic model of PV array is provided considering the PV cell's barrier capacitance and ground capacitance for analysis of electrical characteristics by lightning.
