SolSource Solutions has expanded its Propel prepaid third-party ownership (TPO) product into six states, including Pennsylvania and Colorado, marking a significant growth in its residential solar financing offerings. This expansion allows more homeowners to access fixed-payment solar financing with transparent terms, directly impacting the solar market and consumer options.
Propel, launched earlier this year, replaces traditional escalating payments and hidden fees with a predictable, fixed payment structure. It is available through TriBeam Financial, which provides fixed-payment financing, and includes the transfer of federal tax credits to homeowners. The product is currently offered in Arizona, Texas, Maine, California, Pennsylvania, and Colorado.
According to Chris Couture, CEO of SolSource Solutions, the expansion into Pennsylvania and Colorado aims to bring simplified, honest financing options to thousands more households. Over 180 independent installers now offer Propel across active markets, with ongoing onboarding to scale the platform further. The hardware is supplied exclusively by Enphase Energy, including microinverters and batteries, and the financing is facilitated via the Concert Finance Program.
Impact of Broader State Availability for Homeowners
This expansion broadens access to transparent, fixed-cost solar financing for homeowners across more states, potentially increasing solar adoption. It also demonstrates SolSource’s commitment to scaling innovative financing models, which could influence industry standards and consumer choices in residential solar markets.
