I'm fully off grid (even had utility power but had them remove it). Cook on electric, have electric water heater, using AC and have enough panels and batteries to not even need a backup generator.

This is very cool. I'm guessing you must live somewhere with mild winters. Insulation can do wonders, but it can be overcast for weeks in the north.
Solar panels are so cheap that it makes sense to overbuild, such that even an overcast winter day meets your electricity needs.
I think that depends on where you are. I've heard of 20kW installations producing 500W in December.
Granted 500W isn't nothing, but what if it's snows?

In my experience this requires overbuilding by a factor of 10. That's not a good allocation of money.
