Solar Electric Systems for Income-Qualified Thornton Homeowners

Income qualified Thornton residents can receive rooftop solar at no cost through the City of Thornton and GRID Alternatives. GRID is a non-profit solar company that installs solar electric systems for eligible families who own and live in their own home. Federal grant funding is provided by the City of Thornton. Homeowners can save up to 75% on their electric bill.

Once the panels are installed, the system is the property of the homeowner. GRID Alternatives will assist with the interconnection with Xcel Energy and with service or maintenance to the system. The income limits are 80% of the area's median family income.

To find out if you qualify, contact GRID Alternatives at 720-943-5162 or email
