How much do solar panels cost in 2026?

For a typical U.S. home, solar systems run about $2.50–$3.50 per watt, or roughly $18,000–$26,000 for an average 7–9 kW system. The 30% federal tax credit ended December 31, 2025 for purchased systems, so most 2026 buyers pay close to the full price, though state and local incentives may still help.

Is the 30% federal solar tax credit still available?

No, not for purchased home systems. The federal Residential Clean Energy Credit (Section 25D) ended on December 31, 2025. Systems had to be installed and operational by that date to qualify. In 2026, homeowners who buy solar no longer receive the 30% credit, though many state and local incentives remain.

How long until solar pays for itself?

Most homeowners reach payback in roughly 9–15 years in 2026 — somewhat longer now that the federal credit has ended — after which electricity is essentially free for the rest of the system's life. Payback is fastest in states with high electricity rates and strong sun.

These figures are estimates based on average installed prices (~$3.00/watt), your state's average residential electricity rate, and local sunlight data. The 30% federal tax credit ended Dec. 31, 2025 for purchased systems and is not included; state, utility, or local incentives may still apply. Actual quotes depend on your roof, equipment, and installer. Solar Cost Advisor does not install solar or sell equipment.

Solar cost questions, answered

For a typical U.S. home, solar systems run about $2.50–$3.50 per watt, or roughly $18,000–$26,000 for an average 7–9 kW system. Note that the 30% federal tax credit ended Dec. 31, 2025 for purchased systems, so most 2026 buyers pay close to the full price (state and local incentives may still help). Your exact cost depends on your electricity usage, roof, and state — which is what the calculator above estimates for you.

No — not for purchased home systems. The federal Residential Clean Energy Credit (Section 25D) ended on December 31, 2025 under the 2025 budget law. To have claimed it, a system had to be installed and operational by that date. In 2026, homeowners who buy solar no longer get the 30% credit. (A separate business credit can still apply to third-party-owned leases/PPAs through 2027, claimed by the owner — not you.) Many state and local incentives remain. This is general information, not tax advice — confirm with a tax professional.

Most homeowners reach payback in roughly 9–15 years in 2026 — a bit longer now that the federal credit has ended — after which the electricity is essentially free for the rest of the system's 25+ year life. Payback is fastest in states with high electricity rates and strong sun. The calculator above estimates your specific payback period.
