Do you really want to lease your roof when if the PV company fits cheap panels there's a chance they'll catch fire and burn your house down? One of my riding mates is an insurance assessor and has two burnt out homes on his patch. Checking with my panel supplier he was able to name the panels concerned, I've forgotten though. He assured me there's no problem with Solar World.
I'm not being presumptuous about anything, Teasel. You're carrying a grudge across from another forum though.
