Solar panels are not resistant to lightning. A solar panel struck by lightning will experience severe damage due to the excessive heat and electrical charge in a lightning bolt.
Can lightning damage 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. Many PV systems may not be properly protected against lightning.
4.2. 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.
There are several ways to record the lightning ground flash density such as lightning flash counters, lightning location systems (LLS) and satellite-based optical or radio-frequency radiation detectors,, . 4. Lightning protection on photovoltaic system 4.1. Previous work of lightning effect on PV system
How will a lightning protection system affect PV power generation?
All this kind of destruction will undoubtedly affect the economic aspects or the return on investment that could be earned from PV power generation as well as the cost of repair or replacement to recover from the damage, all of which can be mitigated by implementing a lightning protection system (LPS) .
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 protection work?
So lightning protection is a two part process. First make sure there is a lightning arresting system completely separate from the PV system designed to attract lightning strikes and shunt them to ground. This is where the short, fat, and straight part comes in for all those conductors.
