He doesn't but few on the street do. Could hack something over the summer that provides some charge on my driveway when I am net producing. Not sure if any legal/tax issues with the setup though. An interesting community project.
It might even be a greater option to have a community battery booth(a bank of LFP or the upcoming Sodium ion batteries). Everyone throws their excess energy into it, and it can be a charging station for e-bikes, EVs etc.
