I was even thinking I might be able to mount one or two of the smaller ones on my roof. The HOA that I live in allows for solar, as long as nothing exceeds the roof line. Since my home faces north, I’m thinking two of the smaller ones on the roof, mounted down by the roof edge near the gutter. That would mean it would not be visible from the front, would be below the roof line, and just might make enough power. Might work.
I will have to do more research
There are several solar angle calculators online that will help you see what sort of exposure you can get.
