4 FAQs about Lightning strike risk for photovoltaic panels

Can a PV system withstand a lightning strike?

Due to outdoor installation, PV systems are vulnerable to lightning strikes, which can cause significant damage to the electrical system and pose a safety hazard.

What happens if a solar panel is struck by a lightning strike?

The PV damage caused during a lightning strike. The damage to the panel comes from a high voltage discharge between cables and cells that occur from indirect lightning strikes. The panels show almost zero output power. Due to the induced overvoltage, the effect is severe as the solar panel between spark discharges is much closer.

How does Lightning affect PV panels?

Referring to, , the high magnitude of a lightning impulse current was applied to PV panels by simulation of a direct lightning strike onto the PV panels. The outcome indicated that the efficiency of the PV panel could be reduced as well as the panels may suffer physical deterioration caused by the high lightning impulse voltage/current.

Does a PV system need a lightning protection system?

Necessity of lightning protection on PV system and its barrier An effective lightning protection system (LPS) is necessary for a PV system depending on the location, construction type and utilisation.
