Are solar panels still worth it in 2026?

By the RenoRange team · Reviewed by [EXPERT NAME], [CREDENTIAL] · Updated 2026

Solar economics changed materially for 2026: the federal residential solar tax credit (Section 25D) ended for systems placed in service after December 31, 2025. For years, that credit knocked 30% off a purchased system. Without it, does home solar still make sense? Honest answer: sometimes — and it now depends much more on where you live.

The new math

Installed residential solar runs about $2.50–$3.50 per watt in 2026, so a typical 8 kW system costs $20,000–$28,000. With no federal credit, payback comes purely from avoided electric bills plus any state or utility incentives. At high electric rates (the Northeast, California), payback lands roughly in the 9–13 year range; at cheap-power rates (much of the South and Midwest), it can stretch past 15 — longer than many owners keep the house.

What still cuts the cost

State and utility programs survived the federal change: net-metering or export credits, state rebates, property-tax exemptions, and performance programs in some states. Leases and power-purchase agreements are the other path — third-party owners may still capture separate commercial incentives and pass some through as a lower rate, at the cost of you owning nothing. Compare 25-year totals, not monthly payments.

When solar is still clearly worth it

High electric rates, a south-facing unshaded roof, strong state incentives or net metering, and a long expected stay — check three of those four boxes and purchased solar still pencils. If you check one or none, the honest move in 2026 is to run the numbers before falling for a glossy proposal — which is exactly what the calculator below does with your actual bill.
