The induced voltage generated by lightning electromagnetic (EM) field often damages photovoltaic (PV) panels. To address this issue, a novel solar-cell string wiring is proposed. By the crossover connection of solar-cell strings, the induced voltages are offset by each other. The lightning EM transient of PV array installed on flat ground is computed by using the method of moments. Compared with the conventional wiring, the proposed wiring can not only reduce the induced voltages of most PV panels but also the voltage between the outputs of PV array. The proposed wiring is highly recommended to be used in the PV array on the soil with great resistivity. Moreover, the effect of the proposed solar-cell string wiring on rooftop PV array is assessed. The results indicate that the rooftop PV array with the proposed wiring has a minimum induced voltage. This novel solar-cell string wiring does not require additional protection devices and is easy to implement.
