Sungage Financial is a U.S.-based financial technology company that specializes in financing for residential solar energy systems, battery storage, and related home energy improvements. Founded in 2011 and headquartered in Boston, the company works primarily through partnerships with solar installation companies to help homeowners afford clean energy projects through loans and financing programs.

The company is known for creating one of the first online loan platforms designed specifically for residential solar projects. Its platform allows homeowners to apply for financing digitally, while solar installers can integrate financing options directly into their sales process. Sungage itself is not the direct lender for all loans; instead, it partners with banks and institutional investors to fund the loans.
