SolSource Solutions has expanded its Propel prepaid third-party ownership (TPO) product into Pennsylvania and Colorado, adding to its existing markets in Arizona, Texas, Maine, and California. This expansion allows more homeowners in these states to access fixed-payment solar financing with federal tax credit benefits.
Propel, launched earlier this year, offers homeowners a predictable, fixed payment structure that replaces traditional escalator-based payments and hidden fees. The product is delivered through fixed-payment financing originated by TriBeam Financial, with hardware supplied exclusively by Enphase Energy, including microinverters and batteries. Over 180 independent installers currently offer Propel in active markets, and SolSource plans to continue onboarding new installers as it scales. The expansion into Pennsylvania and Colorado is part of the company’s broader strategy to grow its footprint throughout 2026, with the goal of making transparent, honest solar financing accessible to more households.
According to Chris Couture, CEO of SolSource Solutions, the response to Propel has been positive, with homeowners showing strong interest in simple and transparent financing options. The product also provides the option for homeowners to purchase their systems after five years, leveraging federal tax credits through the financing structure. The expansion is supported by the Concert Finance Program, which facilitates point-of-sale financing via TriBeam Financial.
Impact of Propel Expansion on Solar Financing Access
The expansion of Propel into Pennsylvania and Colorado broadens access to transparent, fixed-payment solar financing for thousands of homeowners, potentially accelerating solar adoption in these states. By replacing complex payment escalators with predictable costs and allowing access to federal tax credits, the product addresses common barriers to solar investment. This move signals a growing trend toward simplified, honest financing options in the residential solar market, which could influence industry standards and consumer preferences moving forward.
