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. In 2020, MadiSUN will be working with Full Spectrum Solar and Midwest Solar Power to design and install all solar systems for the group buy program.

Thanks to improvements in solar technology, the cost to install solar has never been better. In 2020, homeowners will receive a Federal Investment Tax Credit for 26% of the cost of their system.

Note:  the Federal Investment Tax Credits are ramping down.  In 2021 the Federal Investment Tax Credit for homeowners will be 22% of the cost of the system.  In 2022 there will be no Federal Investment Tax Credit for residential solar systems. 

In addition, Wisconsin’s Focus on Energy program offers up to $1,000 in additional rebates. 

If you go solar, you’ll be in good company. From 2016 – 2019, our Group Buys have helped over 100 Madison-area homes install solar. That’s over $2 million in local solar investment and nearly 700 kilowatts of new renewable energy generation in our community!

Why should I go solar with MadiSUN?

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 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 26% of the cost of their system. Through Wisconsin’s Focus on Energy program, solar systems qualify for up to a $1000 cash rebate. Madison homeowners also have the ability to finance 100% of the cost of their system through a low-interest loan through the Clean Energy Credit Union.

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.
