SolSource Solutions and TriBeam Financial introduce Propel, a streamlined TPO financing platform designed to accelerate project deployment and expand access to flexible funding for clean energy partners.
SolSource Solutions, a residential solar and storage finance company, and TriBeam Financial (“TriBeam”), a technology-driven platform that connects large sales channels to low-cost capital providers, have officially launched Propel, a next-generation third-party ownership (TPO) financing product designed to reshape how residential solar and battery storage systems are funded across the United States.
The introduction of Propel marks a significant milestone for the residential clean energy sector at a time when homeowners are increasingly seeking predictable, transparent, and cost-effective financing solutions. As solar adoption accelerates nationwide and battery storage becomes a critical component of home energy resilience, financing structures are playing a larger role in determining accessibility and long-term value for consumers. Propel is positioned as a simplified, compliance-focused solution that aims to eliminate many of the complexities traditionally associated with TPO models.
A New Approach to Residential Solar and Storage Financing
Propel combines SolSource’s proprietary TPO platform with TriBeam’s advanced loan-origination capabilities into a unified, point-of-sale solution. The result is a streamlined financing experience that integrates energy agreements and capital access into one cohesive offering.
Under Propel, homeowners enter into long-term energy agreements — either power purchase agreements (PPAs) or solar leases — directly with SolSource. These agreements require prepayment of amounts due under the contract. Homeowners may satisfy this prepayment requirement either through direct cash payment or by utilizing loans originated by independent capital providers connected through TriBeam’s platform.
Unlike many traditional TPO models that include escalating payment structures, hidden administrative fees, or opaque pricing adjustments, Propel is structured to maintain fixed loan payments. This predictability allows homeowners to better understand the long-term economics of their investment from day one.
In addition, SolSource’s contract terms provide homeowners with the option to obtain ownership of their solar and storage systems beginning after year five of the agreement. This hybrid approach blends the lower upfront cost and operational simplicity of TPO models with a pathway toward eventual ownership — an option many homeowners find appealing as system values mature and energy savings accumulate.
Propel also emphasizes transparency by passing along the value of available tax credits directly to the homeowner. By avoiding price escalators and reducing layered fees, the model seeks to preserve long-term economic value while lowering friction in the purchasing process.
Strategic Partnerships Powering Propel
To ensure strong national scale and operational execution, SolSource has aligned with several leading organizations across the solar ecosystem.
Enphase Energy serves as a strategic partner in the launch of Propel. Enphase will act as the exclusive provider of inverter and battery hardware that meets domestic content requirements. In addition to supplying equipment, Enphase will deliver a suite of services, including Enphase Care operations and maintenance support, access to its Solargraf design and proposal platform, and safe-harboring support for installers and project developers.
Enphase has long been recognized as a pioneer in solar technology. The company was the first to successfully commercialize microinverter technology and has shipped more than 86.4 million microinverters globally. Today, more than 5.1 million Enphase-based systems are deployed across over 160 countries, demonstrating the scalability and reliability of its technology. Through this partnership, Propel customers gain access to industry-leading hardware backed by established service infrastructure.
Distribution and installer logistics will be supported by Greentech Renewables, a division of CED and one of the largest solar distributors in the United States. With more than 100 locations across major U.S. solar markets, Greentech Renewables will provide national distribution, warehousing, and installer support. The company’s logistics expertise and bill-of-material coordination capabilities are expected to reduce installation delays and improve project execution across regions.
TriBeam’s proprietary technology underpins the financing engine of Propel through its Concert Finance program. Concert enables point-of-sale solar and home-energy financing through TriBeam’s established dealer network. By streamlining underwriting processes, ensuring compliance oversight, and connecting dealers to competitive capital providers, TriBeam helps reduce overhead costs and deliver attractive pricing to homeowners.
Together, these partnerships create an integrated ecosystem spanning technology, distribution, capital markets, compliance, and customer service — positioning Propel for rapid yet disciplined expansion nationwide.
Leadership to Drive National Expansion
As part of its growth strategy, SolSource has appointed Chris Couture as Chief Executive Officer. Couture brings deep industry expertise, particularly in residential solar and storage finance.
Prior to joining SolSource, Couture served as Vice President and Head of Customer Financing at Enphase Energy, where he led financing strategy and customer-focused capital programs. Earlier in his career, he held the role of Vice President at SunPower Corporation, overseeing customer financing initiatives and asset management functions.
His experience navigating complex financing structures and building scalable funding programs is expected to play a central role in Propel’s national rollout. Under his leadership, SolSource intends to expand its dealer network, strengthen compliance standards, and refine its homeowner-centric product offerings.
Executive Perspectives
Neil Auerbach, Founder and Executive Chairman of SolSource Solutions and CEO of Hudson Sustainable Group, emphasized the need for reform in traditional TPO structures. He noted that the residential solar and battery storage market increasingly demands straightforward, lower-cost financing solutions that eliminate gimmicks such as hidden fees and escalating payments.
Auerbach highlighted Hudson Sustainable Group’s multi-decade background in solar finance as a foundational element in building Propel. Founded in 2007 and headquartered in Miami with offices in Tokyo, Hudson has mobilized more than $13 billion in capital across over 25 renewable energy investments globally. Its institutional investment experience provides a strong financial backbone to Propel’s long-term strategy.
Chris Couture described Propel as a product the industry has needed for years — one that simplifies the TPO experience and prioritizes homeowner transparency. He expressed confidence that the combined strengths of SolSource’s platform, TriBeam’s capital connectivity, Enphase’s hardware and services, and Greentech’s distribution reach create a powerful framework for responsible scaling.
Alexi Evriviades, CEO of TriBeam Financial, underscored TriBeam’s mission to eliminate inefficiencies in point-of-sale finance. He explained that Propel aligns the interests of homeowners, installers, and capital providers by reducing overhead, maintaining disciplined underwriting, and enabling competitive pricing.
Strengthening the Residential Solar Market
The launch of Propel arrives at a pivotal moment for the U.S. residential solar industry. Rising utility rates, grid reliability concerns, and expanding federal incentives have increased demand for solar-plus-storage systems. At the same time, scrutiny around financing transparency has grown.
By integrating hardware, financing, distribution, and compliance within a single coordinated framework, Propel seeks to restore clarity and trust in TPO financing models. The ability to lock in fixed payments, avoid escalators, pass through tax-credit value, and provide an ownership pathway after five years may significantly improve long-term value perception among homeowners.
With strong institutional backing, established industry partnerships, and leadership experienced in scaling national solar financing programs, SolSource and TriBeam are positioning Propel as a new benchmark in residential solar and battery storage financing.
As the clean energy transition accelerates, financing innovation will remain as critical as technological advancement. Propel represents a strategic step toward making distributed energy more accessible, predictable, and homeowner-focused — potentially setting a new standard for the decade ahead.
