How to Protect Solar PV Modules from Overvoltage and Lightning Strikes in Grid-Tied Systems
Solar photovoltaic (PV) systems, especially grid-tied ones, are increasingly deployed due to their capability to produce renewable energy. However, these systems are vulnerable to external disturbances like overvoltage and lightning strikes. These issues can significantly impact the longevity and efficiency of the PV modules if not adequately protected. This article focuses on the various protection strategies that can be implemented to safeguard solar PV modules in grid-tied systems from overvoltage conditions and lightning strikes. Understanding Overvoltage in Solar PV Systems Overvoltage occurs when the voltage level in a system exceeds the designed capacity. In a solar PV system, overvoltage can result from grid disturbances, improper system design, or a surge caused by lightning strikes. Overvoltage, if not properly mitigated, can lead to severe damage to the PV modules, inverters, and other electrical components, shortening the lifespan of the entire system. Overvoltage scenarios c…
