The Residential Solar 30% Tax Credit Officially Died December 31, 2025: Why June 2026 Quotes Are Suddenly $9,000 Higher and Installers Are Cutting Crews

A homeowner in suburban Cincinnati pulled three quotes for an 8 kW rooftop solar system last week. The cheapest came in at $25,400 before any incentives. Her neighbor installed the same size system in October 2025 and paid about $17,000 after the federal credit. Same panels. Same installer. Roughly $8,400 difference in eight months.

That gap is not a pricing mistake or a regional quirk. The federal Residential Clean Energy Credit, the 30% break that powered the rooftop solar boom for two decades, officially expired for new homeowner-owned systems on December 31, 2025. Cash buyers in June 2026 receive zero federal credit. The industry is still absorbing the shock, and so are quote sheets.

Here is what actually changed, what an honest 2026 quote should look like, who can still capture the 30%, and the deceptive sales tactic homeowners are already running into on doorsteps and in junk mail this spring.

What changed: One law, one deadline, no extension

President Trump signed the One Big Beautiful Bill Act (Public Law 119-21) on July 4, 2025. Tucked inside was the termination of Section 25D of the tax code, the Residential Clean Energy Credit that gave cash-purchase homeowners a 30% federal income tax credit on solar, batteries, and related upgrades. The Section 25C Energy Efficient Home Improvement Credit died at the same time.

The cutoff is specific. According to IRS guidance issued in 2025, the credit applies only to expenditures "made" on or before December 31, 2025. The IRS defines that date as when original installation is completed, not the contract date and not the deposit date. If your panels were energized and inspection-ready by New Year's Eve 2025, you can still claim 25D on your 2025 return. Carryforward of unused credit still works under existing rules, as the Congressional Research Service confirmed in its primary analysis.

If your installer was still pulling permits on January 2, 2026, the credit is gone. There is no retroactive clawback for pre-2026 systems, and there is no homeowner-side safe harbor that lets a 2026 install reach back and grab 25D. Anyone telling you otherwise is misreading the statute, or hoping you are.

The June 2026 quote shock, in dollars per watt

National marketplace data from EnergySage puts installed residential solar in June 2026 at roughly $2.50 to $3.50 per watt before any incentives. For a standard 8 kW system, that means:

• Gross cash price in 2026: $20,000 to $28,000 for panels and inverter alone

• With battery, main panel upgrade, or service mast work: commonly $24,000 to $32,000

• Net cash price in 2025 (same system, same installer): about $17,000 after the 30% credit

The swing is $7,000 to $15,000 depending on configuration. Most of that gap is the credit that no longer exists. A smaller piece is modest hardware and labor drift. SolarReviews' 2026 cost reference tracks the same range and notes that gross panel prices themselves did not jump; the consumer just absorbs the full sticker now.

Why installers are cutting crews

The demand cliff was predictable, and the layoffs started landing within weeks of the deadline. Per February 2026 wire reporting and industry trade coverage:

• Enphase Energy cut roughly 160 jobs, about 6% of its workforce.

• Freedom Forever, the country's second-largest residential installer, withdrew from 10 of its 30 state markets and laid off about 20% of staff.

• Purelight Power filed Chapter 11 in late December 2025, affecting roughly 200 workers.

• Sunnova and Mosaic, two of the highest-profile residential solar finance providers, filed for bankruptcy. Canary Media tied both directly to the credit transition.

Ohm Analytics revised its 2026 residential install forecast from +8% to a contraction of 20 to 25%. Wood Mackenzie projects 2026 will be the lowest install year since 2020, the COVID trough, with no recovery expected until late decade. Per CPA Practice Advisor reporting, installers spent late 2025 racing to close every cash deal before the cutoff. The pipeline they would normally have lined up for spring 2026 was pulled forward into Q4, and the cupboard is bare.

For a homeowner this matters in two practical ways. First, the cheapest bid in your stack may come from a company that will not be around in three years to honor its workmanship warranty. Second, the surviving installers have more crew time than work, which usually means faster scheduling and more room to negotiate on price.

Who still gets 30% in June 2026: leases and PPAs

The commercial Investment Tax Credit, Section 48E, survived OBBBA. It still pays 30% on qualifying solar projects, and crucially it applies when the system is owned by a business, not by you. That is the entire mechanism behind solar leases, power purchase agreements (PPAs), and third-party-owned (TPO) systems.

Here is how the math actually flows, as explained by Utility Dive's trade press coverage and NuWatt Energy's plain-language walkthrough:

• The installer or finance company owns the panels on your roof.

• They claim the 30% Section 48E credit on the system's installed cost.

• They also claim MACRS 5-year accelerated depreciation, with a 20% first-year bonus in 2026.

• The stacked tax benefit lets them offer you a lease payment or a PPA rate that is meaningfully below your utility rate.

• You pay either a fixed monthly lease or a per-kWh rate for the power the system produces.

There is a deadline on this pathway too. Per Electrek's May 2026 deadline explainer, Section 48E projects must begin construction by July 4, 2026 to lock in the full 30%, with systems placed in service by the end of 2027 (some pathways stretch to 2028). After that, 48E phases down too. If you want a TPO system at today's economics, the window closes in early July.

The honest tradeoffs of going TPO

A lease or PPA in 2026 is a real product with real savings, but it is not the same product as a cash purchase. Before you sign:

• You do not own the system. The finance company does. You typically have a purchase option at year 6 or 7, and a buyout at end of term.

• Escalator clauses. Most leases and PPAs raise your payment 1.9% to 2.9% per year. If utility rates rise faster, you win. If they flatten, the gap narrows.

• Home sale friction. Buyers and their lenders need to either assume the lease or see it bought out at closing. Realtors in some markets are getting more cautious about this.

• Lifetime savings are lower than a cash purchase would have been at the old 30% rate. They are still positive, but the finance company keeps a share of the value that a 2025 cash buyer would have kept.

TPO makes sense if you cannot use a tax credit anyway (low federal tax liability), if you do not have $25,000 in cash or a low-rate home equity option, or if you plan to move within a few years and want the savings without the asset. Cash still wins on lifetime net cost when you can afford it, even at 2026 sticker prices, in any state with healthy electricity rates.

State programs are doing more of the work now

The federal 30% is gone for cash buyers, but state stacks still exist and they matter more than ever. Per Solar.com's 2026 incentive roundup and Joule's state-by-state reference:

• New York: NY-Sun pays a declining per-watt block grant, plus a 25% state income tax credit capped at $5,000. Stacked, the state still covers a meaningful share of a typical install.

• Massachusetts: SMART pays generation-based incentives at $0.06 to $0.12 per kWh over 10 to 20 years. Worth reading the fine print, the solar-only adder is currently $0 per kWh in most utility territories, so the real value is the underlying generation rate.

• California: DAC-SASH provides up to about $3 per watt for qualifying homeowners in disadvantaged communities. SGIP pays a rebate on storage. NEM 3.0 has compressed export rates, which makes a battery close to mandatory for the economics to pencil.

• Illinois: Illinois Shines pays SREC lump sums worth roughly $10,000 to $12,000 over 15 years on a typical residential system.

States where the economics genuinely struggle without 25D, because there is no meaningful local program and electricity rates are low: Georgia, Louisiana, Tennessee, West Virginia, and Arkansas. Cash solar in those states in 2026 is a much harder pencil. TPO may be the only realistic path, and even then you should run the numbers carefully.

2026 payback math: three scenarios

Per EnergySage's analysis, payback periods extend roughly 43% longer without the federal credit. The actual range depends heavily on where you live and what you pay for power. Per SolarInfoPath's 2026 state table:

• High electricity rates plus strong state incentives (Connecticut, Massachusetts, New Jersey): payback around 7 to 8 years on a $25,000 system.

• Mid-tier states with active programs (New York, Illinois, much of California): 9 to 12 years.

• States with no local incentives and cheap power (Georgia, Louisiana, Tennessee, West Virginia, Arkansas): 15 to 21 years, which approaches the useful life of the inverters.

One thing to keep in mind: every payback number assumes a flat or modestly rising electricity rate. If your utility files for 8 to 12% rate hikes (and many are), those payback periods shorten in your favor. The bull case for solar post-25D is essentially a bet on continued rate inflation.

Red flags for June 2026 shoppers

The credit is gone, but the marketing has not caught up. Some installers are exploiting that gap. Watch for:

"30% off!" billboards, door-knocks, and mailers. First Response Solar documented the pattern and the U.S. Treasury has issued consumer guidance: some installers inflate their list price about 10% above market, then "discount" it 30% to land back at roughly a competitive price. The customer thinks they captured the federal credit. They did not. The credit no longer exists for cash buyers.

"25D safe harbor" or "we filed before December" claims. The IRS rules do not allow this for homeowner-owned systems installed in 2026. If a salesperson tells you they have a way to get you 25D on a new install this year, get it in writing and run it past a tax professional before you sign.

High-pressure deadline language tied to fake credits. If the urgency in the pitch is about a federal deadline, ask which one. The only real 2026 federal solar deadline is the July 4 construction-start cutoff for Section 48E, and that applies to leases and PPAs, not cash purchases. See EnergySage's consumer-protection guide for the broader pattern of solar misrepresentation.

How to verify a 2026 quote before you sign

• Compare per-watt, not per-system. Divide the total price by the system size in watts. You want $2.50 to $3.50 per watt for a standard install in 2026. Significantly higher needs a justification (battery, MPU, complex roof). Significantly lower deserves scrutiny on equipment quality and warranties.

• Get three bids minimum. The post-cliff market has wide quote spreads. Walking away from the first quote is genuinely cheaper than it was a year ago because crews need work.

• Look up your actual state incentives. The DSIRE database (dsireusa.org) is the federally-maintained reference. Cross-check anything a salesperson tells you about local programs.

• Decide cash vs. TPO before you take pitches. They are different products with different math. Letting a salesperson pivot you mid-meeting usually serves them, not you.

• Verify license, insurance, and warranty terms. Workmanship warranties are only as good as the installer's solvency. Ask how long the company has operated, and what happens to your warranty if they exit your state.

What happens next

The Section 48E commercial credit phases down after 2027, which puts the lease and PPA channel on a longer fuse. State programs in active markets are likely to expand to fill some of the federal gap, but they cannot match the scale of a 30% federal credit. Per the Solar Energy Industries Association's analysis, residential install volumes are not expected to recover to 2024 levels before the end of the decade. That is the industry consensus, not a worst case.

If you were planning to install in 2026, the practical takeaway is simple. Cash purchase economics still work in states with strong utility rates and state programs, just on a longer payback. TPO still delivers 30% benefit through July 4, 2026 on the construction-start clock. And the next 12 months will sort the durable installers from the ones who built their business model on a credit that no longer exists.
