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. . The concept and purpose of grounding in DC systems, such as solar panels and photovoltaic arrays, are the same as in AC systems. However, the grounding process and methods differ slightly, offering multiple options, such as separate grounding or combined grounding. What is Lightning Protection, and Why Does It Matter?. Lightning protection and grounding standards for stems as well as its recommended practices are also discussed in e (IEC) and various other national and inte power plants that are utility owned and/or utility scale (5 MW or greater). The focus of the guide is on d fferences in practices from. . 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).
