We are at the point where batteries are so cheap they are going to leapfrog household solar - at $100 / kWh (half that in china or 1/3rd in actual cell costs) it doesn't make sense to pay thousands for someone to install solar when you can plug and play relatively simple battery and arbitrage using virtual power plant. Even V2G isn't so appealing anymore - actual bidirectional chargers cost 5-10k for some bizarre reason. You can commission equivalent of your cars battery for that, without too much of electrical work.
