Is Solar Worth It in 2026? An Honest Look After the Tax Credit Ended
It’s the first question every homeowner asks, and in 2026 it’s harder to answer than it was a year ago. The 30% federal tax credit that made the math easy is gone for purchased systems. So is solar still worth it? For many homes, yes — but the answer now depends much more on your numbers. Here’s how to think about it honestly.
The short answer
Solar is most likely worth it if all of these are true:
- Your electricity rate is average or high (roughly 15¢/kWh or more).
- Your roof gets good sun (south-facing, little shade).
- You plan to stay in the home for at least 7–10 years.
- You can either pay cash, get a low-rate loan, or use a lease/PPA.
It’s probably not worth it (yet) if you have very cheap power, a heavily shaded or north-facing roof, or you’re planning to move in a few years.
What changed in 2026
The big shift: the Residential Clean Energy Credit (Section 25D) — the 30% credit for systems you buy — expired December 31, 2025. If you purchase a system in 2026, you no longer get that federal credit. (The full story, and the lease/PPA exception that still carries a federal benefit, is in our guide on the federal solar tax credit ending.)
Losing 30% off the top changes the payback math significantly. A system that paid for itself in ~8 years with the credit might now take ~11–12 years. That doesn’t make solar worthless — it makes it a longer-term play.
The real numbers (2026)
Typical residential pricing in 2026, before any state incentives:
| Metric | Typical range (2026) |
|---|---|
| Cost per watt installed | ~$2.50–$3.50 (avg ≈ $2.75) |
| Typical system cost | ~$15,000–$25,000 |
| Average US home electricity use | ~10,500 kWh/year (~865 kWh/mo) |

How to do your own payback math
You only need three numbers:
- System cost (after any state/local incentives) — e.g. $18,000.
- Annual savings = your annual electricity bill the system offsets — e.g. a $150/month bill ≈ $1,800/year.
- Payback = cost ÷ annual savings → $18,000 ÷ $1,800 = 10 years.
After payback, the electricity is essentially free for the remaining life of the panels (warranties typically run 25 years). If your rate rises over time — and US electricity prices have been climbing — your savings grow and payback shrinks.
What tips the math in your favor
- High electricity rates. The more you pay the utility, the more solar saves. This is why solar pencils out faster in high-rate states than in cheap-power states.
- Rising rates. Locking in your own generation hedges against future increases.
- State and local incentives. These are separate from the (now-expired) federal purchase credit and still exist in many states.
- Financing choice. With the purchase credit gone, leases and PPAs (where the provider keeps a federal credit and passes on savings) are worth comparing against buying. See lease vs buy vs PPA.
What works against it
- Cheap electricity. If you pay well under 15¢/kWh, savings are thin.
- Weak roof conditions. Heavy shade, north-facing slopes, or an old roof that needs replacing first all hurt the return.
- Short time horizon. If you’ll move before payback, you may not recoup the cost (though solar can modestly raise home value).
- Net metering changes. In some states, utilities now pay much less for the power you export. California’s shift to NEM 3.0 is the clearest example — it pushed many homeowners toward adding a battery.
Bottom line
In 2026, solar is still worth it for a lot of homes — just not automatically, and not as fast as when the 30% credit was around. Run your own three-number payback, check your state’s incentives, and get more than one quote. If your payback lands under ~10 years and you’re staying put, it’s usually a solid long-term investment.
