Batteries are a thing.
My power load closely correlates to sunlight intensity.
And my 100m^2 figure is already near 150% of baseline.
I’d keep grid connection (if they’ll agree, see CA) for convenience.
Got some more numbers to crunch and graphs to draw, but upshot is full home solar is reasonable if a few limits are accommodated.
It may not work for me because we use a lot of electricity. Although we do use a good portion of gas which reduces our electric consumption. Ironic, huh. Gas is a must if you have solar or wind. Lol.
I have not seriously considered solar and so I haven't run the numbers but I am betting that it is not that great vs $. And takes 10 - 15 years to reach the ROI point. I do know that there are some shady deals and dealers and a person could easily get ripped off.
