Is Solar Worth It in 2026 Without the Federal Tax Credit?

- The federal 30% ITC expired for residential homeowners owning their system on January 1, 2026, removing an upfront $9,000 credit on a $30,000 installation.
- Without the federal credit, the average solar payback period in high-cost states like Massachusetts extends from 2.3 years to 4.1 years, but systems still deliver more than $40,000 in lifetime avoided electricity costs over 25+ years.
- Electricity rates, not the tax credit, remain the primary ROI driver, with states like Massachusetts hitting $0.36/kWh and national averages at $0.18/kWh in early 2026 (up 21% from 2022). These rates are expected to rise an additional 15% by year-end.
The 30% federal solar tax credit is gone.
As of January 1, 2026, homeowners who buy their system with cash or a loan no longer receive the 30% Investment Tax Credit. On a $30,000 installation, that was $9,000 back. It's no longer on the table.
So the question is real: does solar still make financial sense?
By the end of this, you'll know what the numbers actually look like without the credit, which incentives are still available, and whether going solar in 2026 still pays off.
What Changed on January 1, 2026
On July 4, 2025, Congress passed H.R. 1, the "One Big Beautiful Bill," which eliminated the residential solar Investment Tax Credit (Section 25D) for systems installed from January 1, 2026 onward.
The rule is simple: if you own your solar system, bought with cash or a loan, the 30% federal credit is gone.
Three things did survive:
Leases and PPAs: If a third party owns the system on your roof (and you pay a monthly rate to use it), that company still qualifies for the credit through 2027 and can pass the savings to you through lower rates.
Commercial solar (Section 48E): Projects that begin construction before July 4, 2026 can still claim the full 30% commercial credit. This matters for business owners, not residential homeowners.
State and utility incentives: The federal bill did not touch these. More on that below.
The Honest Math in 2026
Here is what the numbers actually show.
Without the federal credit, the average solar payback period extends from roughly 4.3 years to 6.1 years. That is a real change. On a $30,000 system, you are looking at about $1,700 more per year until payback instead of the credit cushioning the difference upfront.
But here is the context: a well‑installed solar system produces energy for 25 years or more. A 6.1‑year payback period on a 25‑year asset still represents an exceptionally strong return. Over the system's lifetime, the average homeowner saves over $40,000 in avoided electricity costs.
The deeper driver of solar ROI has never been the tax credit. It is electricity rates.
In certain parts of the country, electric rates can get as high as $0.36 per kWh. Rates across the nation are increasing, driven by data center demand and grid infrastructure costs. The EIA projects another 13% to 18% increase by the end of 2026.
Solar locks in your rate. The grid does not.
For homeowners paying $0.20/kWh or more (California, Hawaii, Massachusetts, Connecticut, New York), the credit expiry changes the payback math by roughly two years. The 25‑year savings story does not change.
What the ROI Actually Looks Like Without the Credit
A $28,000 system in a state with $0.20/kWh rates and full net metering generates roughly $2,000 to $2,500 in annual energy savings. At that rate, payback lands around 11 to 14 years before state incentives. With state incentives and rising rates factored in, it moves closer to 7 to 9 years.
The after‑credit IRR on a purchased system in a high‑rate state still compares favorably to most fixed‑income alternatives. The credit expiry reduced the return. It did not kill it.
One important note: system costs have also dropped. Solar hardware prices fell roughly 8% in 2025. Installer competition has increased in most markets. The credit is gone, but the baseline cost of going solar is lower than it was three years ago.
Incentives That Are Still on the Table
The federal 30% credit is gone for homeowners who own their system. The incentive landscape is not.
New York: The NY‑Sun program continues to offer per‑watt incentives through the megawatt block structure, with enhanced support for low‑to‑moderate income homeowners through Solar for All. NY also provides a 25% state tax credit (up to $5,000). For installations within the five boroughs, the NYC SEGS Abatement adds a 30% property tax reduction over four years. Together, these state and local incentives effectively mitigate the 2025 repeal of the federal residential tax credit, maintaining a 5–7 year payback period in the ConEd territory.
Massachusetts: A 15% state income tax credit (up to $1,000) remains active. Massachusetts also has one of the strongest net metering programs in the country; however, new systems now participate in the SMART Program (providing fixed‑rate monthly payments for 10 years) rather than the legacy SREC market.
New Jersey: The Successor Solar Incentive Program (SuSI) is active, providing fixed‑rate payments through the Administratively Determined Incentive (ADI) for 15 years; this replaces the volatile legacy SREC market with a predictable certificate value (currently around $85–$95 per MWh) that typically recovers 10% to 20% of the total system cost.
California: State rebates have scaled back, but California's high utility rates (averaging $0.30/kWh or more in many territories) make the ROI math work without them. SGIP incentives remain for battery storage.
Illinois: The Illinois Shines program offers Adjustable Block incentives for residential solar, structured as renewable energy credit payments over 15 years.
Net metering (nationwide): Most states still require utilities to credit excess solar energy you export to the grid. In a well‑sized system, this can reduce your annual electricity bill to near zero. Net metering policy is the single biggest variable in your solar ROI after electricity rates.
$0‑down loans: Financing structures exist that eliminate the upfront cost entirely. With the right loan terms, monthly loan payments come in below your current utility bill from day one. The economics work even without the tax credit when the loan is structured correctly.
The Best Time to Be a Solar Buyer
Here is something worth noting: the credit expiry actually removes one of the most common high‑pressure sales tactics in solar.
For years, installers used "you have to act before the tax credit expires" as a closing lever. That deadline is over. You now have time to compare multiple quotes, vet installers carefully, and move on your timeline, not theirs.
The installers worth working with do not need urgency tactics. They earn the business on price, reviews, and quality.
The price variation between installers is also larger than most homeowners expect. The same system, same equipment, same roof, can be quoted at $22,000 by one company and $29,000 by another. The difference is not quality. It is overhead, sales commissions, and margin.
Getting three or more quotes saves the average homeowner $3,000 to $5,000 on the final price. That is often more than the tax credit would have returned on smaller systems. Your leverage as a buyer has not changed. Installers still compete for your business.

Is Solar Worth It in 2026 for You?
It depends on four things.
Your electricity rate. Above $0.15/kWh, solar pays back strongly. Above $0.20/kWh, it is a clear financial win. The national average is $0.18/kWh and rising.
Your state incentives. New York, Massachusetts, New Jersey, Illinois, and California residents have meaningful state‑level support that partially offsets the federal credit loss.
Your roof. A south‑facing roof with good sun exposure and no major shading produces the most energy. A credible proposal will model your actual roof conditions, not an average.
Your timeline. Homeowners planning to stay 8 to 10 years or more get full benefit from the payback period. Homeowners who move earlier still benefit: solar adds an average of 3% to 4% to home resale value, according to Zillow.
The federal credit is gone. The fundamentals that made solar a strong investment are not.
The Bottom Line
A 6.1‑year payback period on a 25‑year asset, in a market where electricity rates are climbing at 5% per year, is still a strong return. In high‑cost states the payback period is shortened by 2 years.
The tax credit extended the honeymoon. The math never depended on it.
See your system design, compare your installer options, and make the call on your timeline.
