Group Buy for Homes

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 across the city 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.

Thanks to improvements in solar technology, the cost of solar has never been better. Plus, homeowners can receive a Federal Tax Credit for 30% of the cost of their system and Wisconsin’s Focus on Energy program offers up to $2,000 in additional rebates. New this year, homes that don’t qualify for Focus on Energy Incentives can apply for a MadiSun rebate. MadiSUN also offers excellent financing terms through the new Solar Energy Loan Program, in partnership with Summit Credit Union.

And if you go solar, you’ll be in good company. Through 2016 and 2017, our Group Buys have helped 80 Madison-area homes install solar. That’s over $1.2 million in local solar investment over 400 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.

REBATES  •  For Madison homes that are high-quality solar sites but don’t qualify for the statewide Focus on Energy program rebates, the City of Madison is offering a limited pool of rebates to support your solar investment.

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 a preferred installation partner or partners to serve the group buy. When participants sign up, MadiSUN refers them to the selected company for a free site assessment and customized proposal.

FINANCING SOLUTIONS  •  MadiSUN participants are eligible for incentives and financing to lower their costs even further. Participants can receive a Federal Tax Credit equal to 30% of the cost of their system. Through Wisconsin’s Focus on Energy program, solar systems qualify for up to a $2000 cash rebate. Madison homeowners also have the ability to finance 100% of the cost of their system through a low-interest, fixed-rate loan through the Solar Energy Loan Program.

Go solar with MadiSUN in 4 easy steps!


Tell us you’re interested.


We’ll assess your home virtually and give you a call to discuss solar viability for your home. If solar looks like a good investment, a team member from one of our selected contractors will conduct an on-site solar assessment and walk through their installation process with you.


You’ll sign a contract, pay a down payment, and schedule the installation.


Solar will be installed on your home. The City of Madison will inspect the installation, and the local utility will conduct tests to formally interconnect it with their electrical grid. Savings on your utility bill will start immediately.
