The principle is fair, but the specific price can be unfair. Especially if the home as provider could be supplying into spot or other markets. Thats where a neighborhood or coty consortium/ cooperative of community users could make sense to maintain a better pricing deal from the utility.

Sorry, I forgot to add;

1. They also won't allow battery storage while connected to the grid. If they wanted to buy surplus but allowed my to store my own production, I would be fine with it.

2. They also net bill daily. So while I may produce extra within the billing cycle, they zero out excess production daily.
