You can essentially already do that. I live in a place basking with sun most of the year, and have 22k of panels with a 15kw inverter (max allowed before being considered commercial). My production is a wide hill with a considerable plateau, thanks to the amount of panels (as an example, produced 140kwh yesterday). It is clearly not economically viable for most regions, but for us it luckily is

Even more important, if you're on batteries as opposed to grid-tied, your battery costs can go down significantly. Since the worst days of the year tend to be winter and overcast, if you can install enough capacity to still generate a significant fraction of your needs on those days (eg at 10% of summer peak) the size of the required batteries can be much smaller.

It doesn't work so well in the north east, but if weather is only bad for a few days, you might need much less backup or generator power. Batteries and generator power tends to be much less than adding excess solar.

I imagine you sell a lot of electricity back. I can't imagine using anywhere near that much power.

Definitely, haven’t paid an electric bill since the installation, even during the winter
