Lightning (surge) arrestors are designed to absorb voltage spikes caused by electrical storms (or out-of-spec utility power), and effectively allow the surge to bypass power wiring and your equipment. An electrical path to ground will constantly. . Solar PV systems are designed to collect energy from sunlight, but they also have large metallic components including panels, frames, and mounts, along with extensive electrical wiring. Both metal and wiring serve as excellent paths for electrical currents, making solar installations natural. . When lightning damage does occur, it accounts for 32% of weather-related solar panel incidents, making proper protection a valuable investment in system longevity. Solar installations represent significant investments across residential, commercial, and utility-scale projects. Learn about grounding, surge protectors, and lightning rods to prevent costly damage. That is also the 2nd and 3rd major reason. All photos courtesy of NOAA unless otherwise noted.
