Is home solar worth it in 2026? How payback really works

Rooftop solar still makes financial sense for many homes, but the 2026 math is different from the numbers you'll see in older articles. The 30% federal residential credit expired at the end of 2025, so the payback now rests on your system cost, your electricity rate, and your utility's export (net-metering) policy. Here's how to work it out honestly.

Key takeaways

  • The 30% federal residential solar credit (Section 25D) expired December 31, 2025, homeowners who buy a system outright in 2026 receive $0 federal credit.
  • Standard panels run about $2,300–$3,000 per kW installed; a typical 6 kW system is roughly $13,800–$18,000 before any state or utility incentives.
  • Payback = net system cost ÷ annual bill savings, where savings ≈ production × your electricity rate.
  • Your local electricity rate and net-metering credit now matter more than raw sunshine.
  • Adding a battery increases cost by roughly half but adds backup power and self-use value.

How payback is calculated

Solar's return is a payback period, not a coupon. Take your net system cost (after any state or utility incentives) and divide by your estimated annual bill savings. Annual savings is roughly your yearly production in kWh multiplied by the electricity rate you avoid paying.

For example, a 6 kW system in a moderate-sun region might produce around 8,000–9,000 kWh a year. At a typical residential rate that's several hundred to over a thousand dollars of avoided electricity annually, and net cost divided by that figure is your payback in years.

What the 2026 incentive landscape looks like

The headline change is the expiration of the 30% federal credit (25D) with no phase-down, 2026 cash buyers get nothing from it. Many states have also scaled back net metering, replacing full-retail export credits with lower supply-only rates, which lengthens payback where it's happened.

State programs, utility rebates, and SREC markets still add value in some areas, and a lease or PPA can indirectly tap the business 48E credit through 2027. The point: 2026 economics are local, so model your own utility rather than trusting a national average.

What drives your return

  • Electricity rate: the higher the rate you offset, the faster solar pays back. This is often the single biggest factor.
  • Net-metering policy: what your utility pays for exported power swings the return materially; confirm the current rate before you buy.
  • System cost: panel tier, roof complexity, and whether you add a battery set the net price.
  • Roof condition: panels last 25+ years, so install on a roof with plenty of life left, replace an aging roof first.

Frequently asked questions

Is there still a federal solar tax credit in 2026?
No. The 30% residential solar credit (Section 25D) expired December 31, 2025, with no phase-down. Homeowners who buy a system outright in 2026 receive $0 federal credit. Some state programs, utility rebates, and SREC markets still add value, and leases/PPAs can use the business 48E credit through 2027.
What's the payback period on solar now?
It varies widely by location because it depends on your system cost, electricity rate, and net-metering credit. Without the federal credit, expect a longer payback than older national figures suggested, which is exactly why you should model your own utility rate rather than rely on an average.
Do I need a battery?
Not necessarily. A battery adds roughly half again to the project cost. It's most worthwhile if you want backup power during outages or your utility's export credit is weak enough that storing your own power beats exporting it.
