@toodles

unfortunately our roof pitch is only 14 degrees (another reason winter solstice production is pants) so rain and wind isn’t enough to wash everything off.
love the idea of ground mount, but we don’t have an ideal spot unless I build a solar car port at the bottom of the drive. Did you need to apply for planning permission for it?

@papahuhu I read the planning requirements very carefully and took advice. The wording refers to ‘Ground Mounted’ whereas my panels are resting on but not affixed to the ground. As such, I don’t comply due to the very restrictive requirements of a limitation on the square meterage and distance from the boundary with my neighbours …. no planning inspectors have knocked yet!

Are you not concerned about high winds catching hold of panels and relocating them to a neighbour's garden, @toodles?

@toodles

you must have discovered the secrets of quantum gravity to get them to float above the ground then, or are a Jedi 😀

It’s an absurd regulation anyway, how is a solar panel any different to a green house for reflectivity.

@majordennisbloodnok The frames alone weigh over 100 kilos, then there is the weight of the ballast blocks and the panels themselves - maximum height above ground level is approx 20 cm. We are surrounded by high fences (hence the shading problem in winter time) and houses on all four sides. Toodles.
