MadiSUN makes it easy to make your home solar-powered!

Putting solar panels on your home is a great way to lower your energy costs. And you get to switch to a clean, renewable energy source that you can feel good about for years to come.

The MadiSUN solar group purchase program brings together households from across Dane County and uses their collective buying power to get a great deal on rooftop solar at home. Our team of community members reviews competing offers from solar companies across the region and selects a trusted partner to install your system, saving you time and money. All you have to do is fill out our interest form!

Thanks to improvements in solar technology, the cost to install solar is very affordable.

Have questions? Please reach out to our Clean Technology and Programs Manager at ben@renewwisconsin.org.

In addition, Wisconsin’s Focus on Energy program offers up to $2,400 in additional rebates.

If you go solar, you’ll be in good company. From 2016 – 2025, our Group Buys have helped nearly 400 Madison-area homes install solar. That’s over $3.5 million in local solar investment and more than 1,000 kilowatts of new renewable energy generation in our community!

LOWER COSTS  •  Madison residents come together to purchase and install solar systems as a community. By buying together, we can lower the cost for each participant.

EDUCATION  •  Through free community information sessions, we teach residents about how solar works, what return on investment they can expect, and what financing options are available. See if we’re hosting a session in your neighborhood or let us know if you’d like to host one.

SELECTED SOLAR INSTALLER  •  MadiSUN issues a Request for Proposals that is open to dozens of solar installers in the area, who compete to serve the group. A volunteer Advisory Committee helps review each competing bid and selects preferred installation partners to serve the group buy. When participants sign up, MadiSUN refers them to the selected companies for a free site assessment and customized proposal.

FINANCING SOLUTIONS  •  MadiSUN participants may be eligible for Focus on Energy rebates that help reduce the upfront cost of installing solar. For 2026, qualifying residential solar systems can receive $600 per kW, up to $2,400. If you plan to finance your solar installation, your selected solar installer can also help walk you through financing options available for your project. If you would like to compare financing independently, you can also review the solar financing resources on the MadiSUN Solar Financing page.
