Abstract: Lightning strikes can affect photovoltaic generators and their exposed installation sites as well as the sensitive electronics of the inverter. Therefore, it is necessary, to estimate the risk by lightning strikes, and to take these results into account for the design. IEC (EN) 62305-2 states procedures and data for the calculation of the risk resulting from lightning strikes into structures and for the choice of lightning protection systems. Actually, the technical guidelines for installation suggest protecting with SPD’s (surge protective device) both the DC and AC sides of the PV plant. The aim of this paper is to estimate voltages due to lightning discharges and to determine the effective need of lightning protection measures on the basis of the risk analysis and the protection costs.
