Abstract: Photovoltaic (PV) system is easy getting stroke for its outdoor characteristics and defendless protective measures. To provide the quantify basis for PV lightning protection formulation, a lightning transient modeling method is presented. With the PV lightning transient model, the lightning transient response that includes the currents on the branches and the potentials at the nodes of PV frame structure could be calculated. The simulated results reveal that the positions of the striking node and the structure of frame system have pronounced influence to the transient responses. The flowing currents on the frame branches closing to the striking node are significantly higher than distant ones. Meanwhile, the transient potential distribution on supporting frame work has an initial distortion and then tends to approximate equalization.
