From my research, basically the best thing going sorta is the actual tesla shingles and battery, but even then making some sense only for high end homes and commercial stuff. And believing panels last as long as stated along with them staying in business for the warranty. Basically it's a "wait 5 years" if it succeeds and watch costs come down. The shingles very pricey, I think it was like 100k total for average good sized home before rebates etc. Something like 9 to 12k of that is just the battery.

Battery tech is still got some things to overcome, and fortunately costs are coming down some and seen a few possible lithium alternatives coming on line including one by the guy who originally made the lithiums that power all our phones etc.


So suffice to say I'd skip for now. In the very early days it was better when utilities were paying you a lot but theyve been cutting payments so it's a lot harder to recoup investment unless you are eco nut.
