Are photovoltaic panels prone to lightning strikes

Solar panels do not actively attract lightning strikes, as they are not lightning rods, and their height and metal components do not significantly increase the likelihood of a direct strike. . While comprehensive research shows solar installations are remarkably resilient to extreme weather, lightning represents one risk factor worth addressing. When lightning damage does occur, it accounts for 32% of weather-related solar panel incidents, making proper protection a valuable investment. . 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. A typical lightning strike can generate a peak current of 30–200 kA, with voltages reaching up to 100 million volts, all within just a few microseconds. [PDF]
