Solar Panels in Utah: Cost, Payback & ROI (2026)
Is solar still worth it in Utah after the 30% federal tax credit expired? These pre-computed estimates use NREL PVWatts production data and current 10.8¢/kWh Utah electricity rates for a typical home using 900 kWh/month.
Section 25D (30% federal solar tax credit) expired December 31, 2025
All numbers below reflect 2026 math with no federal residential credit. State incentives, where applicable, are noted in the section below.

Is Solar Worth It in Utah in 2026?
Utah's exceptional solar resource at 1,800 kWh/kW/year and relatively low rates of 10.8¢/kWh create a nuanced picture: very high production means systems generate a lot of electricity, but low rates mean each kWh saved is worth less. Payback periods are moderate — not the shortest, but not the longest. Rocky Mountain Power operates under a net metering structure that provides bill credits at near-retail rates.
For a typical Utah home consuming 900 kWh per month, our calculation shows a 6.0 kW system needed for 100% offset. At the current national average installed cost of $2.95/W (LBNL Tracking the Sun 2024), that's $17,700 gross before any state rebates. Year-one savings of $1,166 grow each year as electricity rates escalate — the model assumes 2.5%/year (EIA AEO 2024).
The 13.4 years payback period is moderate — within the national average range of 8–12 years. Over 25 years — the standard warranty period for most premium panels — a Utah homeowner following this profile would save an estimated $37,301 total, for a net benefit of $19,601 after recovering the system cost.
