Buying vs Leasing Solar in 2026: Which Should You Choose?
The 2026 tax-credit shake-up rewrote this decision's math — leasing got relatively stronger, and owning got more honest.
By Alex Rivera, Senior Solar Editor · Updated 2026-07-02Ownership still wins the long game for most creditworthy homeowners in high-rate states: with §25D gone for 2026 purchases, paybacks stretched to roughly 8–13 years in our six-state analysis, but 25 years of near-free production after payoff remains unmatched — and owned systems add appraisable home value. Leasing/PPA gained real relative ground: third-party owners still capture commercial clean-energy credits and can pass savings through, so $0-down TPO offers price better against ownership than they have in years. The rule: if you can buy (cash or sane loan) and will stay put ~8+ years, buy. If capital, credit, or tenure argue otherwise, a low-escalator lease from a durable operator is now a respectable second — read the escalator, the buyout schedule, and the transfer terms before signing.
Buying Solar vs Leasing Solar — At a Glance
| Feature | Buying Solar | Leasing Solar |
|---|---|---|
| Upfront cost | Full price (no 2026 federal credit) | $0 down typical |
| Who owns the system | You | The TPO company |
| Who claims remaining credits | No one (residential §25D ended) | TPO claims commercial credits |
| Typical payback (own) | ~8–13 yrs (our 6-state data) | N/A — pay per month/kWh |
| Years 10–25 economics | Near-free production | Ongoing payments + escalator |
| Escalators | None | 0%–3.5%/yr — compounds hard |
| Maintenance responsibility | Yours (warranties cover most) | TPO's, contractually |
| Home sale | Adds appraisable value | Lease transfer/buyout friction |
| Credit requirement | Loan underwriting | TPO credit check (often ~650+) |
Choose buying if...
- You'll own the home ~8+ years — payback then decades of free power.
- You can pay cash or borrow at a rate that keeps the math positive.
- Appraisable home value and no-strings resale matter to you.
- You want incentive independence now that the federal credit is gone.
Choose leasing/PPA if...
- Upfront capital or loan pricing blocks ownership for you.
- A 0%-or-low escalator quote beats your utility's trajectory in writing.
- Maintenance-free operation for 25 years is worth the premium.
- The operator is durable (fleet scale) and transfer terms are clean.
How did 2026 rewrite the buy-vs-lease math?
The residential Clean Energy Credit (§25D) ended for purchases placed in service after 2025 — homeowners buying in 2026 pay full freight, which stretched our measured six-state paybacks into the 8–13 year band and made per-watt quote discipline the whole ballgame for buyers.
Third-party ownership kept its subsidy: TPO fleets claim commercial credits (§48E-family) on the systems they own, and competitive operators pass a slice through as lower lease/PPA pricing. Result: leasing's relative position is the strongest it's been since the mid-2010s — which is precisely why lease contracts deserve harder reading, not softer.
Why ownership still usually wins anyway
Because the contest is 25 years long. An owned system that pays back in year 10 delivers roughly 15 years of production at maintenance-only cost — in high-rate markets like California, that back half is worth multiples of the upfront premium. A leased system keeps charging monthly forever, and a 2.9% escalator roughly doubles the payment by year 25.
Ownership also survives the home sale better: appraisers credit owned arrays; leases inject assumption paperwork, buyout negotiations, or payoff demands into closings. Our lease-vs-loan-vs-PPA breakdown quantifies these mechanics contract by contract.
When leasing is genuinely the right call
Three profiles: capital-constrained households whose loan quotes are ugly enough to eat the ownership advantage; shorter-tenure owners who'd sell before payback; and payment-first buyers who value contractual maintenance over asset economics. For them, 2026's credit-boosted TPO pricing is a fair product — from a durable operator, at a low escalator, with clean transfer terms.
The diligence trio before signing any lease: full 25-year payment schedule (escalator compounded), buyout table by year, and transfer requirements at sale. Then compare cents-per-kWh against your utility's ten-year trend. If the lease only wins against today's rate, it doesn't win.
Frequently Asked Questions
Common questions about Buying Solar vs Leasing Solar.
Is the solar tax credit really gone in 2026?
For homeowner purchases, yes — §25D ended for systems placed in service after 2025. Third-party owners (lease/PPA companies) still claim commercial credits on systems they own, which subsidizes TPO pricing.
What's the payback on buying solar now?
Roughly 8–13 years across our six research states post-credit, driven by utility rates and install price per watt — California's high rates sit at the fast end, low-rate states at the slow end.
Are solar leases a scam?
No — they're a financing product with real trade-offs. The failure mode is contractual: high escalators, opaque buyouts, and messy transfer terms. Low-escalator leases from durable operators are legitimate, especially post-2026.
What escalator is acceptable?
0% is available and worth paying slightly more monthly for; anything approaching 3% compounds brutally — a 2.9% escalator nearly doubles payments by year 25. Demand the full schedule, not the year-one number.
Which is better for selling my home?
Ownership — appraisers credit owned systems and buyers inherit free power. Leases require assumption or buyout at closing; budget that friction if tenure is uncertain.
