Starting to think about Solar and battery, with emergency power capability
I was looking for a website where I can estimate what can go on my roof in terms of panels. I found several which use satelite photos but they don't get the roof size very accurate (under-sized). Is there one where I can enter the details like this:
The house is rectangular, 8.2m (in line with the apex) and 6.7m (at right angles to the apex). My roof is a symmetric pitched roof, one side facing 125° from North (i.e. approx SE), and the other facing 305° (i.e. approx NW). The roof has an additional overhang of 0.25m past all walls, making it 0.5m larger in both directions. The roof pitch is about 33°. Interlocking concrete roof tiles (if that matters), 1990 construction using premade A-frame roof trusses.
