The 30% federal tax credit for residential solar ended for systems installed after December 31, 2025, and that changed the math every homeowner has to do. The short answer: solar is still worth it for many households in 2026, but the payback is longer, the quotes matter more, and the old rules of thumb no longer apply.
- The 25D residential credit is gone for 2026 installs. Systems placed in service by December 31, 2025 can still claim it on 2025 taxes.
- A typical 7 to 8 kW residential system costs $18,000 to $28,000 before any remaining state incentives in 2026.
- Payback periods stretched from 6 to 9 years to roughly 9 to 14 years in most states.
- Solar still pencils out best for homes with high electric bills, expensive utility rates, and good sun exposure.
- Getting multiple quotes matters more than ever: prices for the same roof can vary 30 to 40 percent between installers.
What actually changed in 2026
For nearly two decades, the federal Investment Tax Credit did the heavy lifting in residential solar economics. Under Section 25D of the tax code, homeowners could claim 30% of their system cost as a credit against their federal taxes. On a $25,000 system, that was $7,500 back. It was the single biggest reason payback periods sat in the 6 to 8 year range through the early 2020s.
The 2025 budget reconciliation law ended 25D for residential systems placed in service after December 31, 2025. “Placed in service” generally means installed and operational, not just contracted or paid for. If your system was up and running by the end of 2025, you can still claim the credit when you file your 2025 taxes using IRS Form 5695. If it goes live in 2026, there is no federal credit to claim. Tax law has edge cases around timing, so confirm your situation with a tax professional rather than relying on a salesperson’s reading.
What did not change: the panels got cheaper, not more expensive. Equipment costs have fallen for a decade, and the Department of Energy continues to track residential installed prices in the same band they have occupied for years. What changed is purely the subsidy math. A system that cost $25,000 in 2025 effectively cost $17,500 after the credit. The same system in 2026 costs the full $25,000. Everything downstream, payback, savings, the lease-vs-buy decision, flows from that one fact.
What solar costs now
Nationally, cash prices for residential solar in 2026 land between $2.50 and $3.50 per watt before incentives, according to marketplace data tracked by EnergySage. That band is wide because local labor, permitting costs, roof complexity, and installer business models vary enormously. Here is what that means for common system sizes:
| System size | Typical homes it fits | Cash price range (2026) |
|---|---|---|
| 5 kW | Small homes, low usage (~500 kWh/month) | $12,500 – $17,500 |
| 7.6 kW | Average US home (~900 kWh/month) | $19,000 – $26,500 |
| 10 kW | Large homes, EVs, electric heat | $25,000 – $35,000 |
| 12 kW+ | Very high usage, future EV plans | $30,000 – $42,000+ |
Two warnings about these numbers. First, financed prices are routinely 15 to 30 percent higher than cash prices because of dealer fees baked into solar loans. A quote at $3.80 per watt on a 25-year loan is not the same as a $3.00 per watt cash quote, and salespeople rarely volunteer the comparison. Second, your quotes will vary more than any national average suggests. Our full breakdown of what a typical home system costs in 2026 walks through the line items, and what installers quote versus what you actually pay explains where the gaps hide.
The new payback math
Payback period is simple division: system cost divided by annual electric bill savings. The credit’s end raised the numerator by about 43% (from 70% of cost back to 100%), which stretched paybacks mechanically. Here is a realistic illustration for a 7.6 kW system at $3.00 per watt ($22,800), producing about 11,000 kWh per year:
| Monthly bill before solar | Annual savings (approx.) | Payback with 2025 credit | Payback in 2026 |
|---|---|---|---|
| $120 | $1,150 | 13.9 years | 19.8 years |
| $180 | $1,730 | 9.2 years | 13.2 years |
| $250 | $2,400 | 6.7 years | 9.5 years |
| $350 | $3,360 | 4.8 years | 6.8 years |
These are illustrations, not promises. Real savings depend on your utility’s rate structure, how much of your production you self-consume, and whether your state still has true net metering. But the pattern is honest: without the credit, solar needs a bigger bill to pay back in a reasonable time. A $120 monthly bill barely justified solar even with the credit; at $250 and up, the math still works well. Our detailed payback analysis runs more scenarios if you want the full numbers.
One more factor: electricity rates keep rising. The EIA reports residential rates climbing steadily for a decade, and every rate increase shortens your payback after installation because your savings are measured against the bill you avoided. Solar is a hedge against future rate hikes, and that hedge got relatively more valuable, not less.
Who solar still makes sense for
Solar in 2026 is not for everyone, but it is clearly worth it for households that check several of these boxes:
- High electric bills. At $200 or more per month, most systems pay back inside 12 years even with zero incentives. High usage is the single best predictor of good solar economics.
- Expensive utility rates. California, Hawaii, New England, and parts of New York charge 25 to 45 cents per kWh. At those rates, every kWh your roof produces is worth two to three times what it is worth in a 12-cent state.
- Good roof and sun. A south or west-facing roof with minimal shade produces meaningfully more than an east-facing or shaded one. Production differences of 20% are common and flow straight to payback.
- You plan to stay. With 9 to 14 year paybacks, solar favors owners who will be in the home at least a decade. Selling in three years changes the calculation toward home value effects instead.
- An EV or electric heat is coming. Adding a major electric load after installing solar means buying cheap kWh from your roof instead of expensive kWh from the grid.
Who should probably wait
Honesty cuts both ways. Solar is a weak investment right now if your monthly bill is under about $120, your roof is heavily shaded or faces north, your utility pays almost nothing for exported power and charges low rates, or you plan to move within five years. In those cases the payback can stretch past 20 years, which is longer than the inverter warranty and uncomfortably close to the panel warranty. Renters, condo owners without roof rights, and homes needing a $15,000 roof replacement first should also pause: solve the roof, then revisit solar.
None of this is permanent. Panel prices continue their slow decline, batteries are getting cheaper every year, and several states are expanding their own incentive programs to fill the federal gap. Waiting two years is a legitimate strategy if your situation is marginal today.
How to make the numbers work
If you are in the “maybe” zone, four levers improve the math. First, get more quotes. The spread between the highest and lowest bid for identical equipment is routinely 30 to 40 percent, and the cheapest reputable bid can cut two to three years off payback by itself. Learn how to read a solar quote line by line before you sign anything.
Second, pay cash or use a low-fee loan if you can. Dealer fees on solar loans often add 20 to 30 percent to the price. Third, check your state programs. Property tax exemptions, state credits, and utility rebates still exist in many states; DSIRE maintains the authoritative database. Fourth, size the system to your actual usage, not the biggest system a salesperson proposes. Oversizing past what your utility credits you for just donates cheap power to the grid.

Is solar still worth it in 2026 without the tax credit?
For many homeowners, yes, but the bar is higher. Homes with monthly bills above $200, high utility rates, and good sun exposure typically see paybacks of 9 to 12 years. Homes with small bills or shaded roofs often do not pencil out anymore.
Can I still get the 30% credit if I sign a contract in 2026?
No. The credit depends on when the system is placed in service (installed and operational), not when you sign. Systems placed in service after December 31, 2025 do not qualify for the 25D residential credit.
Will there be a new federal solar incentive?
As of 2026, no replacement federal credit for residential solar has been enacted. Some states have expanded their own programs, so check DSIRE for your state’s current offerings.
Does leasing still make sense without the credit?
Leases can still make sense if you want zero upfront cost and the monthly payment is clearly below your current bill. But compare the 25-year total cost against buying, because lease escalators compound. Our lease vs purchase guide breaks down the math.
How much has the payback period increased?
Roughly 40 to 50 percent longer than the credit era. A system that paid back in 7 years with the credit typically pays back in 10 to 11 years without it, holding all else equal.
