Solar Lease vs Buying in 2026

For years, leasing was the workaround for homeowners who could not use the federal tax credit: the leasing company claimed it and passed some value through as lower payments. In 2026, with the residential credit gone and commercial credit rules tightened, the lease-vs-buy decision runs on different logic. Here is who, if anyone, still gets a tax credit, and how to choose.

How the old lease credit mechanics worked

Under a solar lease or power purchase agreement (PPA), a company installs panels on your roof, owns them, and sells you the power (lease: fixed monthly payment; PPA: per-kWh rate). Because the company owned the system, it claimed the Section 48 business investment credit, historically 30%, rather than the homeowner’s 25D. In theory, competition forced lessors to pass much of that value to customers through lower payments.

In practice, the pass-through was partial and opaque. Lessor economics bundled the credit with depreciation benefits and cheap capital, and homeowners had no way to verify how much of the 30% reached their monthly price. This is one reason purchased systems consistently showed better lifetime economics in independent analyses: the buyer captured the full credit directly via Form 5695, while the lessee captured whatever the lessor chose to share. Our overview of the post-2025 incentive landscape sets the stage for what follows.

What changed in 2026

Two things changed at once. First, 25D ended for residential systems placed in service after 2025, so buyers lost their direct credit. Second, the commercial-side credits that lessors relied on were also curtailed: the 2025 reconciliation law imposed construction-start deadlines and accelerated phase-downs on solar credits for businesses, with particularly tight timelines for leased residential systems that had been using the commercial credit. The era in which third-party owners could count on a straightforward 30% business credit for new residential leases effectively closed.

The practical consequence: lessors’ costs rose at the same time buyers’ credits vanished, so neither side has a tax advantage anymore. Lease pricing in 2026 reflects unsubsidized economics plus the lessor’s margin, which makes the lease-vs-buy comparison cleaner than it has ever been. You are now comparing financing structures, not tax strategies. Tax nuances remain around projects already under construction and safe-harbor provisions, so treat any lessor claim about “grandfathered credits” with skepticism and verify independently.

Who still gets a tax credit

Short version: almost no one on the residential side for new 2026 systems. Homeowners who buy: no 25D. Homeowners who lease: no 25D (and never had it; the lessor’s business credit is the lessor’s). Lessors: facing phased-down commercial credits with deadline constraints that make new residential lease portfolios far less attractive to finance.

The remaining credit action is mostly commercial and industrial: businesses installing solar on their own properties may still access Section 48E credits subject to construction-start deadlines, and tax-exempt entities have elective-pay provisions in some windows. If you are a homeowner being told a lease gives you “access to tax credits,” understand exactly what that means now: it likely means nothing for you directly. What matters is the payment stream, which brings us to the math.

The lease math without credits

A lease is now purely a financing and service proposition: zero down, fixed payments, maintenance included, no ownership. Evaluate it on those terms. Take a typical 7.6 kW lease at $180/month with a 2.9% annual escalator. Year one costs $2,160. By year 15 the payment is about $270/month; by year 25, about $359/month. Total paid over 25 years: roughly $78,000. Against that, stack 25 years of electric bills without solar, which at 3% annual rate growth on a $200 starting bill totals roughly $73,000. The lease saves little or nothing in that scenario, and that is before considering that you own nothing at the end.

The escalator is the term that kills most leases. A 2.9% escalator sounds small; compounded over 25 years it nearly doubles the payment. Some leases escalate at 3.5%, which is worse. Always model the full 25-year payment stream, not the attractive year-one number. And read the buyout, transfer, and end-of-term clauses: selling a home with a leased system means transferring the lease to the buyer, which complicates sales and has generated a long trail of complaints.

The buy math without credits

Buying the same 7.6 kW system for $22,800 cash (at $3.00/watt) with no credit: against the same $200/month bill growing at 3%, simple payback lands around 9 to 10 years, and 25-year net savings land in the $25,000 to $35,000 range depending on rate growth and degradation. Financed at 8% over 20 years with no dealer fee, total cost runs roughly $36,000, still leaving meaningful lifetime savings. Our payback analysis runs these scenarios in detail.

Ownership also brings the home-value effect: research on owned (not leased) solar shows resale premiums, while leased systems are at best neutral and at worst a complication. Maintenance is the buyer’s responsibility, but modern systems need little: monitoring is largely automated, inverters carry 10 to 25 year warranties, and panels degrade slowly. The “hassle” of ownership is smaller than lessors’ marketing suggests.

How to decide

Run both numbers for your specific quotes. Get a purchase quote (cash price per watt, specified equipment) and a lease quote (full 25-year payment schedule with escalator), then compare total 25-year cost of each against 25 years of projected bills. If the lease’s lifetime cost is within a few thousand of buying and you genuinely value zero-hassle, leasing is defensible. If the gap is $20,000+, as it often is, the convenience is wildly overpriced.

Three questions resolve most cases. Can you afford the purchase, by cash or sensible loan? If yes, buy. Is the lease payment, modeled over the full term with the escalator, clearly below your projected bills? If no, walk away. Does the lease transfer cleanly if you sell? Get the answer in writing before signing. SEIA’s market data shows third-party ownership losing share as purchase economics improved, which tells you which way informed buyers are moving. And whatever you choose, verify the installer’s credentials and reviews first; our guide to 2025 credit eligibility is a reminder of how much fine print matters in this industry, credits or no credits.
