Solar Payback by City (2026)

Solar economics are local. This index covers 1067 U.S. cities, each with an estimated payback derived from the real state electricity rate (EIA 2026), NREL PVWatts v8 production, and state incentives — with city-level solar production modeled from the state value and the city's latitude. Pick your state, then your city.

Modeled estimates: City production figures are modeled from each state's real NREL PVWatts v8 value adjusted for latitude — not a site-specific simulation. Rates are real EIA 2026 YTD state averages; costs are regional estimates. Sources dated (retrieved 2026-08-29). Federal residential ITC (Section 25D) expired Dec 31, 2025.
