I doubt anywhere in the world has an electrical utility designed to support paying for users to produce solar. Folks seem to think it should be 1 to 1 on what you produce should equal whatever you would have paid, ignoring all the other maintenance, redundancy and load balancing the utility has to provide.

Between solar and something like localized battery storage to handle usage surges we could probably handle it better now, but I don’t think anyone is building that kind of system.
