Are you solar curious?
Many recognize solar as an essential part of our US energy mix. Households are thirsty for more and more energy, and there is a massive energy suck from the quickly expanding AI-fueled data center deluge. We are at a major crossroads.
How will we ever meet the demands of “progress” when building new power generation, coal, natural gas, and nuclear, requires massive investment and years to plan and build?
Should we attempt to slow down the AI revolution, which will determine winners and losers for centuries to come?
These are the significant questions that people far smarter than me are trying to find solutions for.
There must be an easier, simpler way to fight the battle for technological supremacy. Can residential solar help relieve the strain on our aging and inadequate energy infrastructure?
This brief article explores how residential solar is trying to be part of the solution and how equity and structured debt investors can support a widely misunderstood industry.
Solar Investment Dilemma
Why don’t we harness the earth's most abundant renewable energy source? The US is playing catch-up in solar adoption and is well behind worldwide rates. Power magazine reports that the United States adoption rate is about 3%, while Germany, Australia, and Italy recorded rates over 20%! However, there is light on the US solar horizon as deployment factors align, leading to a blistering annual growth rate of 24%.
Solar Alignment
1. Technological Advancements: Ongoing innovations in solar technology have increased solar panels' efficiency, durability, and affordability. Advanced energy storage solutions and smart home integration further enhance the appeal of residential solar systems.
2. Declining Costs: Solar panel costs have significantly declined, making solar energy more accessible to homeowners. This cost reduction, combined with various financing options and incentives, has accelerated the adoption of residential solar installations across the country.
3. Government Incentives: Federal and state-level incentives, such as tax credits and rebates, continue to drive the adoption of residential solar. These policies aim to make solar energy more financially attractive for homeowners and support the growth of the renewable energy sector.
4. Consumer Awareness: Growing environmental consciousness among consumers has increased the demand for clean and sustainable energy solutions. Homeowners are increasingly seeking ways to reduce their carbon footprint, and residential solar offers a tangible and practical solution.
As solar-curious investors, we wonder why operational profitability at residential solar companies is so elusive.
Getting to Breakeven
Despite some mighty tailwinds, residential solar companies have struggled to earn a profit, and investor support has waned. As of writing this piece, leading residential solar system providers Sunrun (founded 2007) and Sunnova (founded 2012) are down nearly 90% from their January 2021 highs. Why?
1. High Initial Costs: Despite declining costs, the initial investment required for residential solar installations can still be significant (~$26K). Many homeowners may be deterred by long payback periods (8-10 years payback period). In the case of PPAs and Leases, in which the solar company bears the upfront costs, profitability can not be expected until a large portion of the portfolio has aged 10+ years.
2. Intense Competition: The residential solar market in the US is highly competitive, with numerous companies vying for market share. This competition can lead to pricing pressures, reducing individual companies' profit margins. Additionally, some companies may use aggressive marketing tactics or price wars to attract customers, further eroding profitability.
3. Regulatory Uncertainty: Changes in government policies, regulations, and incentives can impact the economics of residential solar installations. The Inflation Reduction Act (IRA) restored the 30% solar tax credit, boosting the industry. However, Net Metering 3.0 in CA reduced the price paid by utilities to households for excess energy delivered back to the grid, which has significantly impacted the economic benefits of solar, slowing installations.
4. Customer Acquisition Costs: Acquiring new customers can be expensive for residential solar companies. Marketing, advertising, and sales efforts to educate homeowners about the benefits of solar energy and convince them to invest in solar installations incur significant costs. High customer acquisition costs can strain company finances, especially in competitive markets. Mary Powell, Sunrun CEO, indicated on CNBC that customer acquisition costs can be as high 30% of the total solar system cost.
5. Installation Challenges: The complexity of residential solar installations, including site assessment, permitting, and installation logistics, can lead to delays and cost overruns. Unforeseen challenges such as roof repairs, shading issues, or regulatory hurdles can further impact profitability by increasing project costs and timelines.
6. Financing and Cash Flow: Offering financing options such as leases, power purchase agreements (PPAs), or loans can make solar installations more affordable for homeowners. However, managing cash flow and financing arrangements can be challenging for solar companies, particularly smaller firms with limited access to capital.
7. Operational Efficiency: Efficiency in project management, supply chain management, and installation processes is crucial for controlling costs and improving profitability. Inefficient operations, including scheduling delays, inventory management issues, and workforce inefficiencies, can negatively impact the bottom line.
8. Technology and Innovation: Keeping pace with technological advancements and innovation in the solar industry is essential for maintaining competitiveness and profitability. Companies that fail to invest in research and development or adopt new technologies may struggle to differentiate themselves in the market and meet evolving customer demands.
Overall, achieving profitability in the residential solar sector requires navigating a complex landscape of market dynamics, regulatory considerations, operational challenges, and customer preferences. Successful companies must effectively manage costs, differentiate their offerings, and adapt to changing market conditions to thrive in the long term.
Solar ABS
The performance of Solar Asset-Backed Securities (ABS) transactions, which typically involve bundling and securitizing portfolios of residential solar leases, power purchase agreements (PPAs), and loans has generally been positive. The securitization market is a vital part of young solar companies' financing mix, in which they sell the future cashflows from solar assets and use the proceeds to pay operating expenses and grow the business.
The performance of the ABS transactions can vary based on factors such as the quality of the underlying assets, market conditions, and issuer practices. Here are some key points regarding the performance of Solar ABS transactions:
1. Steady Growth: Solar ABS transactions have experienced steady growth over the past decade as solar installations have increased and the solar industry has matured. In the first quarter of 2024, four (4) transactions totaling nearly $1 billion were issued. Market participants expect that total issuance for the year will reach ~4.3 billion which is on pace the prior two (2) years.
2. Investor Appetite: Institutional investors, including pension funds, insurance companies, and asset managers, have shown interest in Solar ABS transactions due to their stable cash flows, long-term revenue streams, and potential for diversification. High-credit-quality transactions with strong underlying assets have attracted significant investor demand.
3. Performance Metrics: Solar ABS transactions are typically rated by credit rating agencies based on factors such as the issuer's creditworthiness, the quality of the underlying assets, and the transaction's structural features. Strong credit enhancement mechanisms, such as overcollateralization and reserve accounts, are often employed to mitigate risks and enhance investor protection. More transactions have experienced rating upgrades as they mature and amortize down reducing the prospect of losses.
4. Default Rates: Historically, default rates on solar leases and PPAs underlying Solar ABS transactions have been low (<1% annually), reflecting the reliable nature of solar energy generation and the creditworthiness of residential and commercial customers. However, defaults can occur due to factors such as customer bankruptcies, property foreclosures, or operational issues. The potential for loss is mitigated by overcollateralization and tranche subordination.
5. Yield and Returns: Solar ABS transactions typically offer investors competitive yields relative to other similarly rated fixed-income investments. The excess yield is often attributed to the industry's young age and the long-term nature of the underlying assets, which often mature in 15 – 25 years. Spreads on newly issued 2024 transactions have been nearly 100bps tighter than those issued in 2023, further indicating broadening industry acceptance and increased liquidity.
6. Regulatory Environment: Changes in government policies, regulations, or incentives related to solar energy, such as tax credits or net metering policies, can impact the performance of Solar ABS transactions. Regulatory uncertainty or unfavorable policy changes may affect the financial viability of solar projects and, consequently, the performance of Solar ABS. However, historically, any policy changes that have been made have not affected previously originated “grandfathered” solar projects. Investors must be mindful of new policy changes that may not offer the same reprieve.
Overall, while Solar ABS transactions have generally performed well, investors should conduct thorough due diligence and assess the credit quality of the underlying assets, issuer practices, and structural features of the transaction before investing. Additionally, monitoring market trends, regulatory developments, and the performance of the solar industry can help investors make informed decisions regarding Solar ABS investments.
