> individuals can get all their energy from the sun, store it with batteries
Good luck storing that energy in batteries through the winter. Having a portion of $50/kWh batteries that cycle once a year results in pretty high energy costs. At some point non-battery storage (e.g. generators running on diesel) take over.
Of course, if people are willing to go totally off-grid then good luck to them.

I think solar will be cheap enough it'll be more like you need to over-provision the panels and just have storage for a week of cloudy days.

1 week of storage that is cycled perhaps once or twice a year. 30 year lifetime, say, so 60 cycles in its lifetime. $50/kWh so perhaps $1/kWh for two (presumably cold and dark) weeks a year.
