By early 2025, the solar securitization market hit nearly $40 billion, showcasing changes in both market structure and the level of investor involvement. These shifts are reshaping how loan securities and deal structures are approached.
Customer-owned solar systems have grown significantly, jumping from just 10% of the market in 2020 to 40% by 2024. This shift has moved the market away from third-party ownership (TPO) models and toward loan-backed securities. Key players like NextEra Energy, through its Everbright subsidiary, and solar manufacturer Qcells, via its EnFin division, have entered the space. These moves by established companies highlight the market's evolution and its potential for further growth.
Sunrun’s $629 million securitization deal in February 2025 serves as a prime example of the market’s growing sophistication:

| Class A-2A | $276.5M | 200 bps | 6.465% | 7.12 years |
| Class A-2B | $250.0M | Private placement | - | - |
This deal includes 39,458 solar systems spread across 20 states, Washington D.C., and Puerto Rico, showcasing a wide geographic footprint. The portfolio's average customer credit score of 738 underscores the quality of the underlying assets.
"Sunrun's first securitization transaction of 2025, the second largest in the industry's history, demonstrates our continued strong execution in the capital markets. Our ability to consistently access deep pools of competitively priced capital to fuel growth is supported by the quality of our assets and our proven track record as an originator and servicer", said Danny Abajian, Sunrun's Chief Financial Officer.
Solar loan securities bring unique benefits, including longer-term exposure compared to traditional consumer asset-backed securities (ABS), while aligning with sustainability goals. In 2024, the U.S. solar industry added nearly 50 GWdc of capacity - a 21% increase from the prior year - with solar accounting for 66% of all new electricity-generating capacity.
While challenges like originator stability and credit performance persist, institutional investors remain drawn to the combination of stable assets and sustainability-focused investments. This focus on environmental, social, and governance (ESG) principles continues to support the market's growth and long-term appeal.
The solar asset-backed securities (ABS) market continues to grow, with shifting trends in pricing and risk shaping its development. Recent data sheds light on key dynamics influencing market performance.
As of Q3 2024, the solar ABS market hit $5 billion in issuances - a 26% increase compared to the same period in 2023. Tesla's latest securitization earned AAA ratings for its senior bonds, thanks to a sequential payment structure that prioritizes returns for senior bondholders.
| Performance Indicator | 2020 | 2024 | Change |
|---|---|---|---|
| Market Size | $30B | $40B | +33% |
| TPO Delinquency Rate | 10% | 15% | +5% |
| Customer Ownership | 10% | 40% | +30% |
While pricing trends are an essential part of the picture, risk metrics provide deeper insights into the market's foundation.
Tesla’s securitizations stand out with strong risk metrics, including an average borrower FICO score of 793 and down payments averaging 13%. However, the solar ABS sector faces challenges that set it apart from more traditional asset classes.
"Sequential structures have more solid cash flow results, and that was one factor that helped Fitch assign a AAA rating, as it better withstands potential losses", notes Hebbertt Soares, a Fitch Analyst.
Key risk factors affecting the market include:
Regional data highlights notable variations in performance. Third-party ownership (TPO) financing has surged to 56% in leading state markets, while loan-financed solar volumes have dropped by 49% year-over-year. Environmental conditions also play a significant role in system performance:
The market is adapting with increased focus on third-party warranty coverage and measures to boost consumer confidence. Meanwhile, rating agencies continue to closely monitor system performance and cash flows to guide investment ratings .
The rules and policies surrounding solar asset-backed securities (ABS) play a key role in shaping the market. From tax incentives to state-level regulations, these factors influence market behavior and investment strategies in significant ways.
The Investment Tax Credit (ITC) has undergone notable changes under the Inflation Reduction Act (IRA), directly impacting solar securitization. With the ITC rate set at 30%, financing opportunities have expanded, particularly for third-party ownership (TPO) structures. In 2022, the solar ABS market saw transactions totaling $3.89 billion, with an average deal size of $324 million. Industry projections suggest TPO could grow by about 23% in the near future, further shaping market trends. As highlighted in a Treasury Department report:
"Federal income tax credits have long been essential in encouraging investment in clean energy projects" - Treasury Department report
The Congressional Budget Office (CBO) also points out that without these tax credits, solar investments between 2024 and 2026 could drop by nearly one-third. While federal tax credits are vital, state policies also play a critical role in influencing the solar ABS market.
At the state level, net metering policies significantly affect the economics of solar projects by providing credits for excess energy production. These policies, in turn, influence the performance of solar ABS. However, shifts in net metering rules have introduced regional risks. For instance, Nevada's temporary elimination of net metering caused over 2,500 job losses and led to the withdrawal of solar companies before the policy was reinstated. Similarly, Louisiana's 2019 switch from net metering to an "avoided cost" model dramatically changed the financial outlook for rooftop solar investments, impacting the performance of related assets.
Regulatory disclosures are another critical factor in the solar ABS market. In early 2025, the Securities and Exchange Commission (SEC) initiated a review of its climate-related disclosure requirements for solar ABS issuers. Although the SEC adopted rules in March 2024 to standardize such disclosures for public companies and offerings, legal challenges delayed their implementation. By February 2025, Acting SEC Chair Mark Uyeda announced a further review of these requirements, citing concerns about their impact on capital markets. As a result, issuers have taken a more cautious approach to disclosures while awaiting final guidance.
The solar asset-backed securities (ABS) market is on a remarkable growth trajectory, with projections showing an increase from $148.39 billion in 2024 to $782.52 billion by 2032. This represents a compound annual growth rate (CAGR) of 23.1%, signaling a shift in investment opportunities and market dynamics.
The integration of energy storage systems with solar installations is reshaping the ABS landscape. In 2024, battery storage capacity is expected to grow by 64%, reaching 7.4 GW - securing its spot as the second-largest share of new capacity additions. Meanwhile, residential solar-plus-storage attachment rates are projected to rise from 14% in 2023 to 25% in 2024.
When combined, solar and storage assets in securitization pools offer more stable revenue streams and improved risk profiles. These benefits stem from consistent cash flows during peak demand periods. As Nick Rogers, Head of Non-Traditional ABS Origination at RBC Capital Markets, explains:
"Fintech lenders helped to start the rooftop energy revolution, but large and global players are positioned to accelerate it, both growing the pie and also taking significant share."
This shift highlights the importance of diversified approaches to investment in the solar sector.
In addition to energy storage, a diversified portfolio strategy strengthens the resilience of solar ABS. The evolution of solar ABS is driving more sophisticated portfolio management practices. For example, utility-scale solar and wind projects accounted for nearly 90% of new energy builds through September 2024, enabling broader investment opportunities.
| Asset Type | Key Characteristics | Market Trends |
|---|---|---|
| Residential Solar | Higher individual loan values | Increasing integration of storage |
| Commercial & Industrial | Stable long-term contracts | Rising demand for corporate PPAs |
| Community Solar | Shared subscription model | Growth in state-level programs |
| Utility-Scale | Large project portfolios | Focus on enhanced grid storage |
Key considerations for the solar ABS market include originator financial stability, regulatory compliance, and credit performance metrics, as highlighted by KBRA. Advances in technology, such as AI and machine learning, are playing a critical role in optimizing system performance and improving risk assessments, while ESG initiatives continue to shape market priorities.
The growing energy demands of data centers are driving the development of larger renewable energy projects, which, in turn, influence the creation of new market standards. These emerging benchmarks are paving the way for future market consolidation and setting the stage for continued growth in the solar ABS sector.
The solar asset-backed securities (ABS) market is riding a wave of growth, highlighted by record-breaking deal volumes and expanding industry activity. This momentum reflects how the market has matured and continues to attract significant investment interest.
One key driver of this growth is the shift in customer ownership models, which have jumped from just 10% in 2020 to an impressive 40% in 2024. Raj Prabhu, CEO of Mercom Capital Group, summed it up perfectly when he said:
"That says more about solar as an asset class. A mature asset class that is an attractive investment."
A standout example of this confidence is Sunrun’s March 2025 securitization of $369 million in residential solar and battery systems. With a 6.36% yield, this transaction underscores the market's resilience and growing appeal, even amid broader economic uncertainties.
The solar ABS market is shaped by a variety of factors, including innovative deal structures and evolving regulations. Utility-scale solar, battery storage, and the increasing energy demands of data centers are expected to drive substantial capacity additions. These trends are further bolstered by investor enthusiasm and supportive regulatory policies.
However, the market isn’t without its challenges. While the Inflation Reduction Act provides substantial backing, rigorous technical due diligence remains essential to manage risks effectively. According to KBRA, solar loan ABS offers unique advantages for investors, such as longer-term exposure and alignment with ESG goals, while also helping homeowners shield themselves from rising utility costs.
Looking ahead, the market is poised to grow further, with institutional investors playing a larger role and market standards continuing to evolve. By 2024, the solar ABS market is expected to reach nearly $40 billion, setting the stage for even more opportunities in the years to come.
The transition from third-party ownership (TPO) models to customer-owned solar systems is shaking up the securitization market in the solar energy industry. Unlike TPO models, which depend on steady cash flows from leases or power purchase agreements, customer-owned systems bring a different kind of underlying asset to the table. These assets often come with more stable returns because they are tied directly to ownership and may even appreciate in value over time.
This shift is also injecting more liquidity into the securitization market, making these assets attractive to a broader pool of investors. With customer-owned systems gaining popularity, favorable market conditions, and the steady rise in solar installations, the residential solar asset-backed securities (ABS) market is experiencing strong growth. This trend is opening up new opportunities for both investors and issuers in the solar financing world.
Solar asset-backed securities (ABS) come with a variety of risks that investors should carefully weigh. These include the reliability of sponsors or servicers, credit defaults, fluctuations in solar insolation, technology malfunctions, and volatility in grid electricity prices. Other challenges may arise from issues like gaps in insurance coverage, complications in lease agreements, or the structural intricacies of the securities themselves.
To navigate these risks, investors can take several proactive steps. For one, standardizing contracts and operational processes can help reduce uncertainties. Diversifying investments across various geographic areas is another effective strategy, as it minimizes exposure to localized risks. Additionally, having better access to performance data allows for more informed and confident decision-making. By tackling these challenges head-on, investors can position themselves more effectively in this expanding market.
Policies like the Investment Tax Credit (ITC) and net metering are key drivers in the expansion of solar securitization markets. The ITC provides a 30% tax credit for solar investments, significantly lowering the upfront costs of solar projects. This makes solar installations more accessible and appealing to homeowners, businesses, and investors alike. As a result, the adoption of solar technology grows, creating a larger pool of financing assets that can be securitized.
On the other hand, net metering allows solar energy producers to sell their surplus electricity back to the grid. This generates a consistent and reliable revenue stream, which adds financial stability to solar projects. For investors, this predictability increases confidence in solar assets, making them more attractive for securitization. Together, these policies not only improve the financial viability of solar projects but also encourage greater engagement in the solar asset-backed securities (ABS) market.
