[Highlander]

That was an interesting link Nix, but as was expected still a mix of opinions,.. an interesting point refering to the panels being earthed well against lightning strikes may protect against EMP,..made me think,.... are panels on our roofs earthed in such a way?,..I have a roof full and have never thought about it, of course everything that is linked after the panels is well earthed, but I wonder about the panels themselves,.. I must find out
