Why Every Solar Salesperson Suddenly Wants You to Lease

A reader in Clovis forwarded me two proposals from the same company, eleven months apart. The October 2025 version quoted a 7.2 kW system at $23,400 with a $7,020 federal credit called out in bold on page one. The August 2026 version quoted the same roof, the same panel count, and never mentioned a purchase price at all — just "$164/month, $0 down." Same company, same rep, same house.

Nothing about that rep's honesty changed. The tax code did.

The credit homeowners could claim is gone. The one companies claim is not.

The One Big Beautiful Bill Act, signed July 4, 2025, repealed Section 25D — the 30% Residential Clean Energy Credit — for expenditures made after December 31, 2025. It did not phase down. There is no 26% year, no 22% year. A homeowner who paid cash for a system in December 2025 claims 30% on Form 5695 Part I. A homeowner who paid cash in January 2026 claims nothing. The same bill killed Section 25C on the same date, which is why the heat pump incentive math also looks different this year.

What survived is Section 48E, the Clean Electricity Investment Credit. That one belongs to whoever owns the generating equipment as a business asset. On a residential rooftop that can never be you — you are not in the electricity business. It can, however, be a tax-equity fund that owns the panels on your roof and sells you the output.

So in 2026 there is exactly one legal structure that still pulls a 30% federal credit into a residential solar deal, and it requires the homeowner not to own the system. Third-party ownership went from roughly half of new residential installs this summer toward a projected two-thirds by the end of the year. That is not the market discovering that leases are good. That is the market following the only remaining credit.

The 30% is calculated on their basis, not your price

Here is the part that gets skipped. When a fund claims 48E, the credit is 30% of the fund's eligible cost basis — its installed cost — not 30% of the retail price you would have paid. A residential rooftop system is far under the one-megawatt threshold, so it qualifies for the full 30% rate without the prevailing-wage and apprenticeship gymnastics larger projects go through. Good for them.

But none of that obligates anyone to pass a defined share of the credit through to you. The credit is an input to how the fund prices your monthly payment. It is not a line item you can audit. When a rep says "you're still getting the 30%," ask what your payment would be if the fund did not qualify. If they cannot answer, you are not being shown a pass-through — you are being shown a payment.

Run the escalator to term before you look at anything else

Every third-party agreement I read gets evaluated in the same order now: escalator first, term second, everything else third. The escalator is a clause that raises your rate a fixed percentage each year, typically between 1.9% and 3.9%. It is the mechanism that makes year-one payments look competitive.

A PPA that starts at 26 cents per kWh with a 2.9% escalator is charging roughly 45 cents per kWh by year 20 — a 73% increase. A $180 monthly lease payment with the same 2.9% escalator collects about $78,000 over a 25-year term. Compare that against a cash purchase of the same system at, say, $3.20 per watt, and the cash number is under a third of it.

Escalator	Year 1 payment	Year 25 payment	25-year total
0%	$180	$180	~$54,000
1.9%	$180	~$283	~$68,300
2.9%	$180	~$358	~$77,700
3.9%	$180	~$451	~$88,800

That comparison is not complete, and I want to be fair about why. Those lease payments are replacing utility bills you would otherwise pay, and retail electricity is also escalating. If your utility raises rates faster than 2.9% a year for 25 years, the escalator is not the villain. In California, where NEM 3.0 already reshaped the ownership math, that is a live argument. The point is that you cannot evaluate the deal without running both curves — and the proposal will only show you one.

Zero-escalator products exist. Several providers now lead with them precisely because a flat rate is easier to sell against a rising utility bill. If a rep tells you escalators are standard and unavoidable, that is a statement about their product, not the market.

The July 4 deadline is real — and it is not yours

You will hear urgency this fall, and some of it is grounded in something true. July 4, 2026 was the statutory begin-construction deadline under the OBBBA for 48E projects. Projects that did not begin construction by then must be placed in service by December 31, 2027 to remain credit-eligible. The rules around how a project proves it began construction have been genuinely chaotic: IRS Notice 2025-42 sharply limited the old 5% cost safe harbor in August 2025, and a federal district court vacated that notice outright in June 2026, restoring the safe harbor while the IRS reconsiders. Projects beginning construction after December 31, 2025 also carry new foreign-entity material-assistance documentation requirements.

All of that is the installer's problem. It is a reason their fund has a clock. It is not a reason you have one. The useful move is to turn the urgency into a written answer: "Has the fund covering my system already begun construction or safe-harbored equipment, and under which test?" A company operating inside a safe-harbored fund will answer that in a sentence. A company using the deadline as a closing tool will change the subject.

Five lines to read before the payment line

1. Escalator rate and term. Multiply it out to the final year. Ask for the number in the contract, not the brochure.
2. Production guarantee versus production estimate. An estimate is marketing. A guarantee names a kWh floor and says what you are paid if the system misses it. Find out which one you have.
3. Transfer on sale. Does the buyer have to qualify on credit? What fee applies? A lease that a buyer's lender balks at becomes your problem at the closing table.
4. Buyout formula. Most are "greater of scheduled amount or fair market value," which means the exit price is not knowable today. Ask how FMV gets determined and by whom.
5. Roof work. If you reroof in year 12, who pays to remove and reinstall the array? Get the dollar figure or the formula. This is the single most common surprise I hear about, and it is why I tell people to settle the roof condition question before any solar contract gets signed.

One more reason to read slowly: enforcement activity around residential solar sales has picked up. Connecticut's attorney general issued a civil investigative demand to a solar company in March 2026 over warranty and complaint-handling practices, and separate state actions have alleged that homeowners were locked into long-term agreements without informed consent, including claims of forged signatures. Those are allegations, not verdicts. They are also a reasonable argument for never signing anything on a tablet a stranger is holding.

State programs did not change — but check who keeps them

The federal repeal left state and utility incentives untouched. New Jersey's SuSI program still pays per megawatt-hour of production for 15 years. Massachusetts SMART still pays a per-kWh adder. California still exempts qualifying solar from property tax reassessment and still funds batteries through SGIP.

Here is the catch: most of those programs pay the system owner. Under a lease or PPA, that is the provider. Some contracts pass state incentives through, some keep them, and a few are ambiguous enough that you would not know without asking. Add it to the written-questions list. If you are comparing offers in California, New Jersey, or Texas, the state-level answer can swing the comparison more than the escalator does.

What I would actually do this fall

Get one cash-or-loan quote and one third-party quote from different companies, not two products from the same rep. Run both to term. If you have real federal tax liability, understand that you no longer have a 30% reason to rush a purchase — and paradoxically that makes this a calmer year to buy, because the deadline pressure that used to distort December is gone. If you have little or no tax liability, a lease may genuinely be your best structure, and it always was.

Either way, the question that matters is not "lease or buy." It is "what does this cost in year 25, and who owns what at the end." Ask that first and most of the 2026 sales scripts stop working.
