Is Solar Worth It in 2026? An Honest Answer

Short answer: it depends on your electricity rate, your sun, and how you pay for the system — and the math changed materially on January 1, 2026. The 30% federal residential tax credit (Section 25D) expired on December 31, 2025. If you buy a system with cash or a loan in 2026, your federal credit is $0. That single change adds roughly two to four years to most payback periods.

That doesn't make solar a bad deal everywhere. It makes it a deal you have to actually run the numbers on, instead of assuming the credit bails you out. Here's how we'd think about it.

What changed in 2026

For about a decade, the federal government refunded 30% of a home solar system's cost through the 25D residential credit. A $24,000 system effectively cost $16,800. That credit is now gone for homeowners who own their systems.

There is a wrinkle worth understanding: the commercial clean-electricity credit (Section 48E) still exists. Homeowners can't claim it — but a leasing company or a PPA provider that owns the panels on your roof can. That's a big reason the market has tilted hard toward third-party ownership in 2026. More on that below.

The three numbers that decide it

Whether solar pays off comes down to three inputs, all local:

• Your electricity price. At $0.32/kWh (California, Massachusetts, much of New England), solar offsets expensive power and pays back fast. At $0.11/kWh (Washington, Louisiana), the same panels save far less.
• Your sun. Arizona and Nevada roofs produce 30–40% more per installed watt than roofs in the Pacific Northwest. Same hardware, very different output.
• Your install price. Cost per watt ranges from roughly $2.20 in competitive markets like Texas and Florida to $3.50+ in the Northeast. A 7 kW system can cost $15,000 or $25,000 depending on where you live.

Put high rates, good sun, and a competitive installer together and solar still pays back in well under 10 years. Put low rates, mediocre sun, and a pricey installer together and it may never beat just paying the utility. Our solar cost calculator runs your state's actual numbers so you're not guessing.

So what's a realistic payback now?

For a typical owner-occupied home buying with cash or a loan in 2026:

• Great markets (high rates, strong sun, cheap installs): roughly 7–9 years.
• Average markets: roughly 10–13 years.
• Weak markets (low rates or poor sun): often 15+ years, sometimes longer than the warranty.

Panels are warrantied for 25 years and typically keep producing past that, so even a 12-year payback leaves a decade-plus of nearly free electricity. The question is whether you'll stay in the home long enough — and whether you'd rather have that capital working elsewhere.

Lease and PPA: the 2026 workaround

Because the leasing company can still claim the Section 48E commercial credit, third-party ownership is the one channel where the federal subsidy survives. With a lease or power-purchase agreement (PPA):

• You put $0 down and pay a fixed monthly amount (lease) or a per-kWh rate (PPA).
• The provider owns, insures, and maintains the system.
• You typically save 10–25% versus your utility bill from day one — less than owning, but with no upfront cost and no maintenance risk.

The trade-off: you don't own the asset, the savings are smaller, and an escalator clause can erode them over time. A lease can also complicate a home sale. We break the decision down in solar lease vs. buy in 2026.

Net metering matters more than ever

With the credit gone, the value of the power you export to the grid carries more weight. Full 1:1 net metering (you get retail credit for every exported kWh) makes solar dramatically better than NEM 3.0–style policies that pay wholesale rates for exports. If your state has moved to low export credit, adding a battery — or simply sizing the system to your own usage rather than overproducing — changes the calculus. Size it right with our sizing calculator.

Quick gut check

Solar is probably worth it for you in 2026 if most of these are true:

• Your electricity rate is above ~$0.20/kWh and rising.
• Your roof gets good, unshaded sun (south or west-facing helps).
• You'll stay in the home at least 8–10 years, or you're comfortable with a lease.
• You have favorable net metering, or you're sizing to your own load.

If only one or two are true, look hard at a lease/PPA — or wait. There's no federal deadline pressuring you to buy this year anymore.

Run your own number

National averages are a starting point, not an answer. The same roof can pay back in 8 years or 18 depending on your state's rates, sun, and install prices. Plug in your monthly bill and state to see your real payback, system size, and 25-year savings — with the math shown.
