Community Solar Garden❏What is a Community Solar Garden?
❏A developer owns a PV array and sells the electricity to subscribers.
❏Why is it beneficial to the University of Minnesota?❏lower risk for the University❏Don’t have to worry about
maintenance❏get billed for energy
consumption
Community Solar Garden3 Ways to Participate in CSG
❏Lease property to a developer:❏Pay for space, and buy electricity from the developer.
❏Develop own CSG:❏Control over project, but much more cost and risk.
❏Purchase power from a CSG:❏Pay utility bill to developer that owns the site.
Outreach❏MN is a national leader on
renewable energy❏Outreach campaign to move
decision makers❏Develop messaging around
solar❏Website for publicity,
petition collection❏Get articles in campus, local
media❏Run campaign to get alumni,
student, staff support
