Do solar panels need lightning protection? The short answer is: it depends on your location, system size, and local lightning activity-but most systems benefit from some level of protection.
Annex D of IEC 62305-3 deals specifically with the protection of photovoltaic installations. It covers in particular the positioning of PV panels in protection zones, the separation distances to be observed between down conductors and DC cables, and the rules for grounding chassis.
In this guide, we'll crack open the toolbox of professional welding skills specifically for PV station brackets, complete with real-world examples that'll make you rethink your current approach.
For standard PV power stations, grounding resistance should be below 4 ohms; for large-scale PV power stations or areas with frequent lightning, it should be below 1 ohm.
Lightning protection systems (LPS) provide a protective zone to assure against direct strikes to PV systems by utilizing basic principles of air terminals, down conductors, equipotential bonding, separation distances and a low‐impedance grounding electrode system.
