Hi Wayne, A couple of things I would become familiar with before getting too deep into home solar: 1. UL 1741 2. "As of October 2019, the Tesla Powerwall 2 costs $14,600 for the recommended two units (plus $2,500 to $4,500 for installation) in the US; this price does not include the cost of solar panels." / 1. Rooftop solar -- not looking too good these days. Sounds like the power companies would just rather you didn't ... "They" have rules in place (UL 1741), .. turning the table on grid tie home solar. Old way -- individual uses the grid as a battery to back up their home solar. New way -- power company turns your home solar down to almost no output, only to use it as a 'peaker plant' under high grid demand. (or just discourage you from installing it in the first place) http://evtv.me/2019/06/grid-wars/ / 2. Return on investment calculations https://en.wikipedia.org/wiki/Tesla_Powerwall It's hard to know what to believe ... isn't it?
