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.
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.
