What happens when lightning strikes a PV module?
The solar electric system is designed to sustain a lightning strike by being adequately grounded under National Electric Code. The NEC stipulates methods to ensure safety, not necessarily survivability. That said, a direct lightening strike will most likely damage some or all of the modules. The remaining equipment and inverter should be OK. Typically a homeowner’s insurance policy will cover damage but it’s always recommended to contact an insurance agent to discuss coverage of solar electric systems.
