They came and surveyed our place and turned us down on the grounds that the houses on the street behind us, at the top of the hill, would over shadow us. I found this rather strange as in the summer Trish and I can sit out side on the side where the panels would be from about 10.00 to sunset and never see a shadow unless a cloud crosses the sun.
They turned me down saying my roof (it's an ordinary semi) wasn't a suitable shape for the free panel but someone could come out and discuss if I wanted to buy panels. My friend however did get hers free with no catches.
