Netmetering?

Net metering is a billing arrangement that allows solar system owners to receive credits for the excess electricity they generate and send back to the grid. When your solar panels produce more electricity than you need, the surplus is automatically fed back into the grid. The utility company then credits you for the excess energy, which can offset or reduce your future electricity bills.

Credited to customer's next bill at retail rate (including generation, transmission and distribution) for systems 100 kW or less, and at generation rate for larger systems up to 1MW For virtual net-metered community solar systems, excess credits carry over to a customer's next bill.
