A worked example: 8 kW in Utah
An 8 kW system — about 19 × 425-watt panels — at Utah's assumed installed cost of $2.40–$3.15 per watt runs roughly $19,200–$25,200 before incentives. At about 1,450 kWh of production per installed kW, it would generate around 11,600 kWh per year. Valuing self-consumed electricity at the assumed $0.12/kWh retail rate and exports conservatively, first-year savings land near $1,147 — a simple payback of roughly 17–22 years.
There is no federal tax credit in that math: the Section 25D residential credit ended for systems installed after December 31, 2025. State or utility incentives, where they exist, would shorten payback from here.
Net metering in Utah
Utah’s Rocky Mountain Power credits exports at a net billing export rate well below retail, set through rate proceedings. Municipal utilities vary.
Utah solar incentives
Utah’s state solar tax credit phased down to zero for systems installed after 2023. No significant statewide incentive remains.
What changes a Utah solar quote?
Equipment, roof condition, electrical upgrades, permitting, labor, system size, batteries and financing can all change the installed price. Savings also depend on the specific utility rate, how much solar electricity the home uses directly, and what the utility pays for exports.
Frequently asked questions
How much do solar panels cost in Utah?
Using an assumed installed cost of $2.40–$3.15 per watt, a typical 8 kW home system in Utah costs roughly $19,200–$25,200 before incentives. Smaller and larger systems scale roughly with size, though small systems cost more per watt.
Is solar worth it in Utah?
With Utah electricity around $0.12/kWh and production around 1,450 kWh per installed kW per year, an 8 kW system could save roughly $1,147 in year one, for a simple payback of about 17–22 years with no federal credit. Whether that is "worth it" depends on your rate plan, export compensation, roof, and how long you plan to stay in the home.
Does Utah have net metering?
Utah’s Rocky Mountain Power credits exports at a net billing export rate well below retail, set through rate proceedings. Municipal utilities vary.
What solar incentives does Utah offer in 2026?
Utah’s state solar tax credit phased down to zero for systems installed after 2023. No significant statewide incentive remains. Note that the federal Section 25D residential credit ended for systems installed after December 31, 2025, so state, local and utility programs are now the main incentives for purchased systems.
Is there still a federal solar tax credit in Utah?
No — the 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act. Leased or PPA systems may still benefit indirectly because the system owner can claim the commercial 48E credit through 2027.
