How are solar panels fixed to a roof?
I ask because I'd like to buy and install our PV after we have built the roof. I'd like to build the clips / fixing system into the roof at the time we build the roof, rather than dig around in all that expensive insulation and waterproofing after it has been fitted. We are putting the rafters in in the next week or so, and that would be the time to install the anchor points for the panels
I have searched YT and found the usual nutcases: Watching most of the videos makes me wince - simple 8mm roofing screws screwed right into the roof with no regard whatever for water ingress. And people carrying heavy weights merrily waltzing around on a steeply pitched roof with absolutely no regard for safety
@Construction Channel (he isn't a nutcase) hasn't done his yet, so I can't watch what he's done. Hurry up Ed will you, please?
Are there any guidelines for attaching solar panels, any regulations I need to know about ?
