Short answer: for many US homeowners, yes, but the maths changed on January 1, 2026. The 30% federal tax credit for solar you buy yourself has ended, so a typical system now takes longer to pay for itself. Rising electricity prices pull the other way. Whether it is worth it for you comes down to three numbers: what you pay per kWh, how much of your solar power you use yourself, and what the system costs where you live.
This guide explains what changed, shows the payback maths with and without the old credit, and tells you which situations still make sense.
What changed in 2026
1. The 30% credit for homeowner-owned solar ended
The federal Residential Clean Energy Credit (Section 25D) covered 30% of the cost of solar panels and home batteries you own. The 2025 budget law ended it for systems placed in service after December 31, 2025. If your system was switched on in 2026, there is no federal credit for it, even if you signed the contract in 2025.
2. Leases and power purchase agreements can still get a credit
If a solar company owns the panels on your roof (a lease or a PPA), the company can still claim a commercial credit (Section 48E). For projects that began construction after July 4, 2026, the system generally has to be in service by December 31, 2027. Nothing forces the company to pass that saving on to you, so compare the lease price with the cost of buying outright.
3. Electricity keeps getting more expensive
The average US residential price was 18.83¢ per kWh in April 2026, up from 17.55¢ a year earlier, a rise of about 7%. Every kWh your panels replace is worth more than it was. In high-price states such as California, New York and Massachusetts, it is worth far more than the average.
4. Power you send back to the grid is often worth less
Many utilities no longer credit exported solar at the full retail price. California's Net Billing Tariff (often called NEM 3.0) pays for exports at "avoided cost" rates that are usually a fraction of what you pay to buy power. Other states have similar plans. So the more of your solar you use yourself, the better the payback.
The payback maths, with real numbers
Here is a typical 8 kW system at the 2026 national average quote of about $2.60 per watt, in a location with 4.5 peak sun hours a day and an electricity price of 18.2¢ per kWh (EIA's forecast average for 2026).
| Step | Working | Result |
|---|---|---|
| System cost | 8,000 W × $2.60 | $20,800 |
| Yearly production | 8 kW × 4.5 h × 365 × 0.8 (real-world losses) | about 10,500 kWh |
| Yearly saving, all power used at home or fully credited | 10,500 × $0.182 | about $1,910 |
| Yearly saving, half exported at 5¢ | 5,250 × $0.182 + 5,250 × $0.05 | about $1,220 |
| Scenario | Upfront cost | Simple payback |
|---|---|---|
| 2025, with the 30% credit, full credit for exports | $14,560 | about 7.6 years |
| 2026, no credit, full credit for exports | $20,800 | about 10.9 years |
| 2026, no credit, half exported at 5¢ | $20,800 | about 17 years |
Panels usually carry 25-year performance warranties, so a 10 to 12 year payback still leaves more than a decade of low-cost power. A 17-year payback is marginal. These are simple paybacks: they ignore electricity price rises (which shorten payback), panel degradation of roughly 0.5% a year, financing costs and maintenance (which lengthen it).

Buy, lease or wait?
- Buying with cash gives the best long-term return if you plan to stay in the home, but you now pay the full price.
- A solar loan works when the monthly payment is close to or below the bill it replaces. At 7 to 9% interest, payback stretches by several years.
- A lease or PPA needs no upfront money and may reflect the company's 48E credit. You do not own the system, savings are smaller, and the contract can complicate selling your home. Read the escalator clause: a price that rises 3% a year can outpace your utility.
- Waiting rarely helps: equipment prices are fairly flat and electricity prices are rising. The exception is if a state or utility programme you qualify for opens soon.
Is a battery worth adding?
Home batteries lost the same 30% federal credit, so they are expensive again. A battery pays for itself mainly when your utility pays little for exports and charges much more in the evening than at midday (time-of-use rates). It also keeps your essentials running in an outage, which has value a payback number does not capture. If backup is the main goal, a portable power station may cover your fridge, lights and internet for far less; see our guide to choosing a solar generator for home backup.
Who should still go solar in 2026
Good candidates:
- You pay well above the national average per kWh (roughly 25¢ or more).
- Your roof faces south or west with little shade and does not need replacing soon.
- Your utility still credits exports at or near retail, or you use most of your power during the day.
- You plan to stay at least 10 years.
- A state, utility or local rebate is available to you.
Probably not yet:
- Your electricity is cheap (under about 13¢ per kWh).
- Your roof is shaded, north-facing or near the end of its life.
- You expect to move within five years.
- Most of your solar would be exported for a low credit and a battery does not fit your budget.
Frequently asked questions
Can I still get the 30% solar tax credit in 2026?
Not for a system you own that was placed in service after December 31, 2025. The commercial credit can still apply to leased systems and PPAs owned by a solar company, within the deadlines above. Confirm your situation with a tax professional.
I signed my contract in 2025 but the system went live in 2026. Do I qualify?
Generally no. The residential credit depends on when the system is placed in service (installed and ready to use), not when you signed.
How long do solar panels take to pay for themselves in 2026?
Without the federal credit, roughly 10 to 12 years is typical where exports are credited near retail, and longer where exports earn little. High electricity prices and good sun shorten it.
Do state incentives still exist?
Yes, in some places: state tax credits, utility rebates, property-tax exemptions and solar renewable energy certificates (SRECs). They vary widely and change often, so check your state energy office and utility before you get quotes.
