Solar power in Madison, Wisconsin

Madison Electric and Gas offers its Madison customers a net metering program. Madison Gas and Electric will pay its solar customers for excess electricity their solar system generates at the full retail rate of electricity. The utility measures electricity usage every 15 minutes and if energy production exceeds energy consumption, the customer is credited on their bill. 

Madison residents can take advantage of the MadiSUN Focus on Energy rebate. This incentive provides a rebate equal to 12% of the installed cost of a solar system, up to $2,000. Combine this with the federal solar tax credit and almost half of the cost of your system is covered! And that doesn’t take into account how much you’ll save through net metering.
