When Is a Solar Lease Actually the Right Call?

Before July 2025, the answer to "is leasing solar the right call" was almost always no. The federal tax credit went to whoever owned the system, ownership produced 20+ years of bill savings, and leases captured a small slice of the value for the homeowner while the leasing company kept most of it. The One Big Beautiful Bill Act changed that math by terminating the residential Section 25D tax credit on December 31, 2025, leaving the commercial Section 48E credit intact only for third-party owners. The result: in 2026 and beyond, a lease or PPA is the only way for most homeowners to indirectly access the 30% federal credit. That doesn\u2019t make leases the right answer for everyone, but it does flip the analysis for a meaningful share of the market.

Why the math changed in 2026

The Inflation Reduction Act of 2022 set the federal residential solar tax credit at 30% through 2032, with a step-down to 2034. Under that framework, a homeowner who bought solar with cash or a loan claimed the credit themselves, and a homeowner who leased solar got nothing from the federal government (the leasing company captured the credit). Owning was unambiguously better.

The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, accelerated termination of the residential credit by nearly a decade. Section 25D, which covered customer-owned residential solar, ended for systems installed after December 31, 2025. Section 48E, the commercial credit, was preserved with new deadlines: projects beginning construction by July 4, 2026 have until December 31, 2030 to be placed in service; projects starting later must be placed in service by December 31, 2027.

Section 48E applies to any entity that owns a qualifying clean energy system, including a solar leasing company that owns equipment installed on a residential roof. The credit goes to the system owner (the leasing company), and the electricity benefits the homeowner. The leasing company can also claim accelerated depreciation (MACRS) and, in qualifying cases, stack bonus adders for domestic content and energy communities that can push the effective credit to 40% or even 50% of system cost.

Practical consequence: in 2026, the only way a residential customer indirectly accesses the 30%+ federal tax credit is through a third-party-owned system (lease or PPA). The leasing company captures the credit and decides how much to pass through to the homeowner via lower payments. Some pass through most of it; some keep most of it.

The four cases where a lease is now defensible

With that context, here are the situations where a solar lease or PPA in 2026 is genuinely the right call:

Case 1: You can\u2019t qualify for a solar loan and can\u2019t pay cash

Solar loans typically require a FICO score of 640\u2013660+, and the best APRs are reserved for 700+. Below that threshold, traditional solar financing becomes hard to access. A lease or PPA typically underwrites at lower credit thresholds (often 600+, with some programs accepting 580). If your credit puts loan financing out of reach and you don\u2019t have $20,000+ in cash on hand, a lease or PPA is the practical way to get solar at all. The credit-quality bar is the dominant constraint here, not the optimization question.

Case 2: You can\u2019t use the tax credit yourself (retirees, low federal tax liability)

Before OBBBA, this was already the strongest case for leasing: homeowners with insufficient federal tax liability to absorb a $6,000+ credit got partial or no value from Section 25D. Now that Section 25D is gone, this situation no longer favors leases over loans on tax grounds alone, but it does explain why leasing makes sense for retirees on Social Security or anyone whose federal tax bill is small. The leasing company captures the Section 48E credit on your behalf; the value flows through to you via the lease pricing. Consult a qualified tax advisor about how the credit interacts with your specific situation.

Case 3: You\u2019re moving in 3\u20137 years and want some solar savings without the ownership headache

A 20-year solar loan on a home you might sell in 5 years is a complicated proposition. The owned system adds measurable resale value (Lawrence Berkeley National Laboratory\u2019s Selling into the Sun research puts the premium around $4 per watt for owned systems), but you carry a remaining loan balance that needs to be paid off or transferred at sale. A lease has its own transfer complications, but it doesn\u2019t involve a loan payoff. For homeowners with shorter time horizons who still want some solar savings during their ownership period, a lease with a clear transfer process can be a workable middle ground.

Case 4: You want a system but don\u2019t want to own the equipment

Some homeowners simply prefer not to own a depreciating asset on their roof that they\u2019ll be responsible for maintaining, monitoring, and eventually replacing. A lease shifts these responsibilities to the leasing company: they own the equipment, they monitor production, they handle repairs, they replace components that fail. For a homeowner who values minimal-hassle ownership over maximum long-term return, this is a real tradeoff worth considering. The lower lifetime savings buys you a different kind of relationship with the system.

When a lease is still the wrong call

Even with the post-OBBBA math, leases remain the worse choice in several common situations:

You can pay cash and have meaningful federal tax liability. Wait, you say, didn\u2019t the federal residential credit go away? Yes, but cash ownership still wins on lifetime savings against any lease structure, even with the 48E pass-through. The leasing company\u2019s captured profit margin and the lease escalator clauses produce 25-year math that\u2019s materially worse than owned cash, even without the federal credit on the owned side.

You have FICO 700+ and want a 10\u201315 year loan. A traditional solar loan on an owned system produces better lifetime economics than a lease in most states, especially with the new federal tax credit context. The loss of the 25D credit hurts the owned-with-loan case relative to its old self, but it doesn\u2019t flip the comparison versus leases.

You\u2019re in a state with strong SREC markets (NJ, MD, MA, IL). Some state-level programs require system ownership to capture the value. Massachusetts SMART payments, for example, go to the system owner; if you lease, the SMART payments go to the leasing company, not you. The leasing company should factor SMART revenue into the lease pricing, but verify how that pass-through is structured.

You plan to stay in the home 10+ years and can finance. The escalator clause compounds painfully over long contract terms. A 2.9% annual escalator turns a $120/month year-1 payment into roughly $235/month by year 25. A fixed-rate loan over 15 years produces lower lifetime cost and the system is paid off in the back half of its life.

What to watch for in a lease contract

If a lease or PPA is the right structure for your situation, these contract terms determine whether you\u2019re getting a fair deal or a bad one:

The escalator rate. The annual percentage your payment increases. Anything above 2% compounds heavily over 20+ years. Look for flat-rate (0% escalator) contracts when available; they usually have slightly higher year-1 payments but better long-term math.

The buyout formula. How much it costs to buy the system from the leasing company at year 5\u20136 (after tax-credit recapture for them) and at end of term. Some buyouts are fair-market-value; some use formulas that result in buyouts of 60\u201380% of original system price even after 6 years of use. Get the formula in writing.

The transfer process. Exactly what happens when you sell the home. The buyer\u2019s credit qualification requirements, the seller\u2019s buyout option price, any transfer fees. This is the most common source of regret for lease customers.

The pass-through math. Ask the lease provider for the cash-equivalent system price (what they would charge if you paid upfront) and compare to the total of all your lease payments. The difference reveals how much of the Section 48E credit value flows to you versus stays with the leasing company. Some providers pass through 25\u201330% of system cost; some pass through 5\u201310%. The variation is large.

The production guarantee. Most reputable PPAs include a minimum production guarantee with credit or compensation if the system underperforms. Verify what threshold triggers compensation and what the compensation is.

The maintenance and monitoring inclusions. One of the real benefits of TPO is that the leasing company handles maintenance, monitoring, and equipment replacement during the contract. Verify what specifically is included; some "leases" are really thinly-disguised loans that don\u2019t actually transfer maintenance responsibility.

The honest comparison versus cash and loan

Pulling it together for an apples-to-apples comparison on a $25,000 system in a state with strong solar economics:

• Cash purchase (2026): $25,000 upfront, no federal credit, full electricity savings over 25 years. Typical net lifetime value: $35,000\u2013$50,000 depending on state. Best lifetime economics for those who can do it.
• Solar loan (15-year, 8% APR, 2026): $0 down, monthly payment around $240, no federal credit on the owned system. Typical net lifetime value: $20,000\u2013$35,000 depending on state. Strong middle ground for credit-qualified homeowners.
• Solar lease (20-year, 1.99% escalator, 2026): $0 down, monthly payment around $100\u2013$130, leasing company captures Section 48E credit and (in theory) prices the lease lower as a result. Typical net lifetime value: $8,000\u2013$20,000 depending on state and provider. Worst lifetime economics but lowest qualification barrier.
• Solar PPA (20-year, 0\u20131.99% escalator, 2026): Similar economics to a lease but priced per kWh of production. Typical net lifetime value: $8,000\u2013$22,000 depending on state and provider.

The gap between cash/loan ownership and lease/PPA is now narrower than it was pre-OBBBA, but it still exists. The structure of who captures the tax credit and how the leasing company prices it determines how narrow.

What to do next

If you\u2019ve worked through the four cases above and one of them describes your situation, the next step is comparing actual lease and PPA offers. The pass-through math varies enormously between providers; the best way to evaluate them is to collect multiple quotes and ask each provider for the cash-equivalent system price along with the lease terms.

Our solar calculator gives you a baseline system size and savings estimate for your specific roof. When you\u2019re ready, compare quotes from pre-screened local installers; most offer both ownership and TPO financing structures and can model both for your home. The right answer depends on your specific credit, your tax situation, your time horizon, and your state\u2019s incentive landscape.
