I think that's one use case when having solar panels on your roof, this way you can also help make the grid even more distributed and resilient by having your own storage. Sometimes you might not even need the solar you can just take very cheap electricity from the grid during the day and sell it back in the evening or use it in the evening yourself

One of those cases where selfishness actually benefits others, just don't disconnect from the grid, that's a dick move if you have neighbors

If you have solar panels on your house, and your car isn't at home when that sun is shining, then that would be a good use of one of these for a residential application.

well its usually not in your basement, but should be outside in a home sized battery cage (similar to those used in parking lots to charge EVs). in a more ideal time period, itll just be another external installment like outdoor AC units. to get there, home energy storage has to get cheap enough so that people installing solar at home also opt for energy storage.

one of the big problems EV have is most charge at home at night when peak usage is at instead of the most opportune time, which is when the sun is up during working hours. Its why theres a movement to install charging stations at workplace buildings as a benefit to workers (no longer pay for "gas"). If the average home user had a battery wall, then you can just circumvent that problem alltogether.
