What happens if a PV system is not protected against lightning?

Many PV systems may not be properly protected against lightning. Due to this exposure, the PV systems may be liable to suffer a crucial impact in a way that can lead towards severe damage for instances; failure of the electrical and electronic parts in the building or PV installation and disruption of their normal operation.

What happens if lightning strikes a PV system?

If a surge occurs when any personnel are present, it will jeopardize their safety as well. Indirect lightning strikes can be fatal if the person is within 60 feet from the point of the lightning strike . When a PV system is located on an industrial site, the business operations and equipment are also at jeopardy.

Why are solar PV inverters so expensive?

Inverters are expensive, but for industrial applications, an even more expensive failure is the cost of downtime. When lightning strikes a solar PV system, it causes an induced transient current and voltage within the solar PV system wire loops.

What is the effect of induced overvoltage on solar panels?

Due to the induced overvoltage, the effect is severe as the solar panel between spark discharges is much closer.
