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. . By their very nature, photovoltaic (PV) arrays are generally constructed in large, open, and unobstructed locations. If lightning occurrences are present in those locations, the system may be highly susceptible to a lightning strike. Factors that influence lightning interaction with solar installations: 🔍 Important clarification:. . Lightning is the number one cause of catastrophic failures in solar electric systems and components. That is also the 2nd and 3rd major reason. All photos courtesy of NOAA unless otherwise noted. Robust protection measures ensure the continuity of service and. . Investigating damage to fuses and circuit breakers caused by lightning (poor grounding). The collection area for PV plants are large. Grounding systems have to consist of meshes (20m x 20m/ 40m x 40m).
