jon, as an electrical engineer and one who uses solar and gensets to power up his RV for full time living, I'm very interested in this subject and have studied and pondered about it a lot. As far as domestic solar the efficiency, initial cost, and any ?? actual cost savings or payback (if ever or any) depends on if your utility allows Grid Tie or you use battery energy storage (or if you even have a grid available ) or not ??? There are several self contained (uses battery energy storage and Inverters) units near me MOSTLY in the Amish community maybe 5000 or so watts subject to what their Bishop permits. If I had a home unit Id use ground mount versus roof solar to make sweeping off the snow possible......... Also Lithium Iron Phosphate and other battery technology, although very pricey initially, is improving the use of solar

NOTE as far as pure economics any PAYBACK may or may not ever come about ???? (Lots of variables and unknowns like sun and wind and installation costs and utility cost etc etc) HOWEVER its still a persons free choice REGARDLESS if anyone here likes or chooses it or not and regardless of economics, Solar and Wind and Off Grid is NOT for everyone.

Your desire to use the otherwise wasted heat energy of generators etc for home or water heating is certainly "feasible" with air to air heat exchangers HOWEVER the cost and efficiency and payback are in question.

This is one of those topics with several different and opposing opinions ITS NOT FOR EVERYONE but I enjoy it and of course to each their own free choices if they like solar and gensets or backup OR THEY HATE IT and again REGARDLESS if it suits anyones economic or payback criteria HEAT HOWEVER YALL PLEASE make your choices and let others make theirs. I wont argue against your decisions and expect the same respect in return

I came across this Prager University video regarding Solar and found it "INTERESTING". Im NOT saying its right or wrong, yes or no, ONLY "interesting", if you have an issue with it take it up with the author its HIS work certainly not mine
