I'm thinking every house has its own panels, and its own batteries. Grid is optional. You'll have to be more careful about energy usage perhaps, and maybe personally invest up-front for enough battery and power storage. Maybe the grid is still connected and you can sell excess power, or connect in an emergency (maybe it's expensive?). I do have very little reason to doubt that costs for batteries won't come down drastically in the future. If it doesn't, it might just be an investment you make when owning a home. Just thinking out loud here.
