It’s a stretch, I realize. Panels are getting better and cheaper. I would like to try unless it’s a complete boondoggle. I’m willing to concede use of other appliances to maintain charge when needed.
I think the Tesla power wall goes for about $5K. You could obvious make it work, and there are mini splits that are made for solar power, but I doubt you would ever save any money on your utility bill. If you want to do it just to be off the grid, that’s another story.
