Yeah, solar isn't for everyone. There are plenty of ways to reduce energy loss. We've very slowly been redoing the rooms in the house one by one, down to bare studs. New insulation where needed, filling cracks and voids to stop drafts. I was actually quite surprised to see blown insulation in the ceiling when we put the new roof on. We probably could/should have added some more, however finds didn't permit us to do so. We're eventually planning an addition to the house, with that new windows in the whole house. Takes time when you're doing that stuff for yourself. (I'm sure as you know.)
We selected our panels and inverter based in what my Aunt, Uncle and father in law have. The inverter company isn't very old, but I'm not super worried about finding another inverter if this one goes out. Nothing other then the bi directional meter came from or through the power company, nor do they offer any incentives for going solar. Our rates doubled back in 2020. Basically made the solar a no brainer at that point.
