Are you planning to finance a home solar or battery installation in the next year?

SolSource has closed $300 million in tax credit and warehouse financing to support the expansion of its Propel solar and storage product. This funding enables the service to launch in Connecticut, Illinois, Massachusetts, Ohio, Oregon, Rhode Island, and Washington.

Why it matters

This financing allows SolSource to increase its geographic footprint, giving more households access to solar and storage systems. By monetizing tax credits for consumers, the company aims to lower the barrier to entry for residential renewable energy adoption.

SolSource raised $300 million in new capital to grow its footprint to 13 states. This includes a recent expansion into seven new states where homeowners can now utilize the Propel system for solar acquisition.

The players

SolSource

A renewable energy provider that offers solar and storage systems by monetizing tax credits for homeowners.

TriBeam Financial

A financial services firm that originates fixed-payment loans for customers acquiring home energy hardware.

Enphase Energy

A manufacturer of microinverter and battery technology used in residential energy storage systems.

Greentech Renewables

A distribution and service company that supports the installation of renewable energy equipment.

The details

The Propel system works by helping homeowners monetize tax credits to offset the costs of acquiring solar and battery hardware. Customers can finance these systems through fixed-payment loans originated by TriBeam Financial. The hardware, including microinverters and batteries, is supplied by Enphase Energy, while installation and local support are managed through Greentech Renewables.

Timeline

  1. SolSource launched nationwide operations in early 2026.

  2. The company closed $300 million in financing on October 1, 2026.

  3. Additional market openings are scheduled for Q4 2026.

The Home Front

This development follows a trend of private firms streamlining the use of the Inflation Reduction Act's residential energy tax credits to reduce upfront household costs. It highlights an ongoing shift where installers bundle financing, tax incentives, and hardware into single packages.

If you are considering home solar, research whether your state is among the 13 currently served by SolSource. When evaluating these agreements, request a full breakdown of the fixed-payment loan terms and compare the total cost of ownership against quotes from local, independent installers.

The takeaway

The expansion of service-based solar models indicates that financing mechanisms are becoming as critical to residential energy as the hardware itself. Review your utility bill and home energy usage data to determine if a solar-plus-storage system aligns with your long-term household budget.

What happens next

SolSource is scheduled to open additional markets in the fourth quarter of 2026.
