There's an whole alphabet soup of V2x technologies: https://en.wikipedia.org/wiki/Vehicle-to-grid
The simplest is V1G, that's simply charging your car when there's spare power on the grid, right up to full V2G where lots of EVs form distributed grid scale storage. V2H is an intermediate step, like using a battery bank with your solar PV to help power your home.
One thing that solar PV won't do, is run your home during a power failure. I don't think anyone is yet making kit for domestic PV that will do a reliable changeover into "island" mode. You don't want your PV and/or batteries to try and feed the whole street when the power fails. They won't do it and it's a hazard for the linesmen.
