Very good sir you have done your homework
As an engineer with 30 years in the business Id be happy to give you free advice
Is it safe to say that putting a bunch of solar now doesn't add much to the resale of the home?
If I knew today that I'd get a significant portion of my money back I'd go ahead and get solar now w/o care of if my wife and I downsize and move out in a few years. As it is I'm a bit timid in going into solar unless I know I'm going to be around long enough to get my money's worth out of it. Does that sound like a good plan?
