HI, I am installing solar panels on roof. would like advise as regards lightning protection.?

We Answered:

I don't know that solar panels require lightning protection anymore than the rest of the roof surface area.
There isn't anything about a solar panel that would attract lightning nearly as much as a standard TV tower.

I have a small solar system at my weekend peoperty & have had the solar panels installed for about 10 years without any lightning protection or ground connection directly to the panels themselves.

I have a ground connection just to the batteries with a 4 AWG stranded wire to a grounding stake driven about 4 ft into the ground.

I wouldn't try grounding the panels unless the manufacturer recommends it. I would think that grounding the panels will be more likely to attract lightning to the panels rather than protect them from it.
