"Convincing someone to attach something to their house has significant costs. Like, "over $2000 per install" significant." Not any more. We've got 50-state legal solar stuff where you just lay the panels out in the yard, literally plug them into your wall outlet, and every outlet on that circuit is energized. You can even leave it hooked to your power at night time, as the junction boxes have barrier rectifier diodes that prevent the panels from consuming power at night. Install costs are becoming almost negligible due to advancing technology. Cell efficiency is up there. Typical monocrystalline panels run 20+% now days (and look utterly gorgeous - https://imgur.com/a/sZGtYmB https://imgur.com/a/sZGtYmB - picture from my job.) Opportunity costs? Each cell runs on average $1.00 for most manufacturers, so you just need to shop around. A typical 60-cell panel at 300W runs about $150-200. Most of your concerns have not been concerns for about 5 years.
