The Project
The Solar Commons Project has created the tools for a new, commons-based model of community solar ownership to be implemented throughout the US.
The twenty-first century energy transition will generate billions of dollars in energy savings from solar technologies. Our goal is to ensure that these savings can stay in the hands of local communities to build community wealth. We work in “living labscommunity groups that co-develop the research and test the prototypes of the Solar Commons Toolkit” with community partners who use our legal and digital dashboard tools to transparently share solar energy savings through community trusts. We are making available a free, robust solar commons toolkit so that, just as the sun shines for everyone, the sun’s common wealth can be claimed and distributed by solar commoning communities for decades to come.

School Solar Commoning
Our first two Solar Commons prototypes are with schools. In Tuscon, Arizona and northern Minnesota, our Solar Commons legal agreements made schools the long-term community stewards of the common wealth trust funds. Schools use school participatory budgeting to annually share the wealth in their neighborhoods for community benefit. We created an interactive game to introduce the idea of commons to the school children. In the game, the players take turns selecting cards that contain scenarios about cooperating with nature, neighbors, and community.
By placing tiles, the players build their own neighborhoods while learning about social resiliency, environmental responsibility, and sharing the sun’s commonwealth. In Arizona, the schoolyard mural ties in themes of the Solar Commons game. In Minnesota, the game includes Ojibwe language elements and teachings. School solar commoners use our digital dashboard to track solar savings going to the trust and engage citizen science curriculum. The dashboard makes visible the sun’s solarity next to data from other types of place-based common wealth such as air quality, water quality and, in northern MN, the health of wild rice (Manoomin).

Value and Scalability Studies

The Solar Commons Project embeds solar technology in social and ecological relationships that support equitable local livelihoods for low-income communities in rural and urban regions. Research from Rocky Mountain Institute (RMI) has demonstrated the capacity of the Solar Commons Model to iterate across the US within the span of a decade. RMI found that the Solar Commons could produce a positive net present value to donors as it proliferates across the US.

Research Team
The Solar Commons Project is hosted by the Minnesota Design Center at the University of Minnesota’s College of Design. The project is led by legal anthropologist Prof. Kathryn Milun. who collaborates with community and university researchers from several disciplines including law, public art, architecture, engineering, economics, and computer science. Learn about the team.
Partners
From hot and cold climates, our partners work with the research team on Solar Commons legal, economic, and governance tools. Partners include community and tribal groups in Minnesota and Arizona as well as the University of Arizona School of Art, the Sustainable Economy Law Center in California, and the solar manufacturing company Heliene, Inc. in Minnesota. Learn more about our partners.
Funders
This Project has been supported by financial contributions from many: the US Department of Energy which awarded the Tucson Solar Commons a “Sunny Award for Equitable Community Solar.” In Arizona we received grants from the Pulliam Charitable Trust, the Lodestar Foundation and the US Green Building Council (Arizona Chapter). In Minnesota, the Institute on the Environment at the University of Minnesota and the MN Department of Commerce Solar on Public Buildings Program and others. Learn more about our funders.
