The product, already active in Arizona, Texas, Maine, and California, offers homeowners fixed payments and access to federal tax credits, providing a transparent alternative to traditional solar financing.

Since its launch in February 2026, Propel has seen positive response, prompting the company to expand into Pennsylvania and Colorado. Currently, over 180 independent installers offer Propel across the active markets, with SolSource continuing to onboard new installers as the platform scales. The hardware is exclusively provided by Enphase Energy, including microinverters and batteries, with financing handled through the Concert Finance Program.
