Can lightning cause a photovoltaic system failure?
Lightning can cause photovoltaic (PV) system failures as lightning that strikes the system from a great distance away, or even between clouds, can generate high-voltage surges.
Can a PV system be struck by lightning?
A PV system installed above the protective zone offered by the existing Lightning Protection System may be at risk of receiving a direct lightning strike. This could make the existing Lightning Protection System non-compliant and provide a path for lightning currents to enter the building and endanger life.
