Best way to fix solar panels to a flat GRP roof?
Hi, I’ve just bought some large plug in solar panels. They’re about 2mx1m and im planning on putting them on my flat roof. It’s in Manchester and the roof is above the 1st floor so relatively exposed. Im trying to decide between ballast and fixings. Has anybody got experience with this? What did you do? One option im also considering would be to screw metal brackets over the edge of the roof and through the soffit and into the end of the joists/wall plate.
