Stop thinking so big, and sell a kit that is affordable out the door that chops $100 a month off my electric bill? No net metering, no politics, just a simple package of 5 panels and a powerwall & existing wiring. Like a much smaller scale island power project,, but spread to the masses in scale.
If I have say a $147 power bill, sell me a kit that can take that bill to say $27 a month grid connected. Don't want to gid share by state regs, just want to engineer this math to a $27 grid bill. You take the $1200 profit per year over so many years.
Small, but in scale, very big.
Just give me a $100 a month bling solar/storage X 300 million US electric coustomers.
PS, James Dyson, (just a reminder) your V10 battery storage/charging/hr stills sucks. 9 minutes run/68 minutes charge, "really", charge this battery!!!
