We have one roof that is theoretically appropriate for solar. It is on the garage. House roof faces Northwest and Northeast. That is so the big gable windows face (roughly) south. Having big windows, facing south, with a big overhang, is a form of solar.
Half of the garage roof faces south/southeast and is reasonably clear of trees blocking it. I'm sure to be ideal more trees would have to be cut. Some, but not all, of those trees are slated to be cut for view reasons anyway.
Here's the south facing gable, from two weeks ago with the overhang, my passive solar:

Generally I'm afflicted with something I call longterm thinking disease. Essentially I hate redoing things because I didn't consider the "long run." For example, this house will be connected to a septic field that was built 20 years ago, large enough for a three bedroom house. Back then, I built that septic field "just in case" this house ever got built. The guy who did the work thought I was insane to spend that money for a place I used 30x a year. Lo and behold, in this case, that investment is paying off.
I digress. The garage roof that is ok for solar, I COULD have built it with panels, but I'm anxious about having enough money to finish the project. I should be ok, but I am really sensitive about having an awesome garage, and big bucks in a house that I can't afford to finish. That feels like a colossal fuckup that I would never forgive. So I put the regular metal roof on. I'll certainly be curious to live there to see how much sun that side of the roof actual gets. It's a pretty steep roof so it should shed snow.
My mom has a natural gas Generac whole house genny and it is awesome. It detects outages and turns itself on. She doesn't even know when it goes on. In some big storm a few years it ran for four days. It's quiet too.
Almost no progress the last ten days. Probably at least in part my fault. I'd said my top priority was getting the metal roof on and when it is really hot that's not happening. Also two storms have created a lot of havoc and damage for other clients. I believe I haven't suffered any damage.
