The grounding lug is used to bring the excess flow of current to the earth to protect panels. Each long rail needs a grounding lug at the end.

The grounding lug brings the excess flow of current to the earth to protect the panels - the earth connection point of the PV system.
Each long rail needs a grounding lug at the end - plan one lug per long rail in your grounding design.
It connects the rail to the grounding conductor that carries excess current to the earth, protecting the panels from fault current.
It routes excess current safely to the earth to protect the panels, so every long rail gets its defined earth path.
