How far is it from the roof edge?
When I did my C&G course it was 300mm from the roof edge & 60cm from chimney and that in order to reduce the wind load the rule of thumb for the array was 5 times the distance between the modules and roof surface. Do bare in mind England & Wales have to satisfy building regs. so not particularly appropiate for Scotland.
I’ll dig into it later but 200mm comes to mind however, in the mean time south Larnarkshire advices:
If your property doesn’t come into any of the above categories then you do not need to apply for planning permission:
“when attached to your house or flat, the solar panels will project more than one metre from any outside wall of the house, or any part of the roof or chimney”
You could ring buildg/planning control for a definate answer from roof edge.
