Solar Panels in Utah (UT)

Last updated: February 24, 2026

Everything you need to know about going solar in Utah (UT) — costs, savings, incentives, and the best equipment for your climate.

Federal Residential Solar Tax Credit Repealed

The 30% residential solar tax credit (Section 25D) was repealed in early 2026. Homeowners who installed solar before the repeal can still claim the credit. Commercial projects retain the 30% ITC under Section 48/48E. Utah state incentives remain available.

Solar Irradiance in Utah (2026)

Utah receives an average of 5.6 peak sun hours per day annually, equivalent to roughly 2044 kWh/m² per year of global horizontal irradiance (GHI). Summer peaks reach about 7.3 h/day, while winter lows drop to around 3.4 h/day.

This places Utah in the excellent solar irradiance band compared with other US states. At 5.6 kWh/m²/day, each 1 kW of rooftop solar in Utah generates approximately 1,594 kWh/year (assuming 78% system performance after inverter, soiling, and temperature losses), which makes an 8 kW system produce around 16,352 kWh per year.

Data source: NREL National Solar Radiation Database (NSRDB), 1998-2020 typical meteorological year averages. Utah (UT) values reflect the statewide average; coastal, mountain, and desert microclimates can vary by ±15% from this figure.

Utah Solar Incentives (2026)

Federal residential tax credit was repealed in early 2026. Utah continues to offer the following state and utility-level programs:

Incentive Value Eligibility Deadline Source
Federal Section 25D ITC 0% (Repealed Q1 2026) N/A Was 12/31/2025 IRS
Residential Renewable Energy Tax Credit 25% (cap $400) 25% credit, max $400 UT resident; primary residence Through 2026 UT OED
Net metering (capped) Verify with state agency DSIRE
Property tax exemption Verify with state agency DSIRE

⚠ Always verify state incentive deadlines, caps, and eligibility before signing a solar contract — programs change annually and many have annual funding caps that exhaust mid-year.

Major utility companies in Utah

Check your utility's net metering policy, interconnection requirements, and rate structure before installing — rules vary significantly within Utah:

  • Rocky Mountain Power (PacifiCorp)
  • Dixie Power
  • Murray City Power

Each utility has different rate structures, net metering caps, and time-of-use schedules. Visit your utility's website for current solar interconnection requirements and queue times.

Net metering in Utah

Status: Net billing (NEM ended 2017; Solar Export Credit)

Export rate: Export credit ~$0.045-0.06/kWh (declines yearly)

System size cap: 25 kW residential

⚠ NEM rules can be amended by state public utility commissions and individual utilities — verify with your utility before committing. Caps and rates shown reflect the most common residential tariff as of 2026.

Solar Incentives in Utah

Federal Residential ITC (Section 25D) -- Repealed

The 30% federal residential solar tax credit (Section 25D) was repealed in early 2026. Homeowners who installed solar before the repeal may still claim the credit for that tax year. Commercial solar projects continue to receive the 30% ITC under Section 48/48E.

State Incentives Available

Utah offers state-level solar incentives that remain available despite the federal ITC repeal. Check with your local utility and the DSIRE database for current programs.

Frequently Asked Questions

How much do solar panels cost in Utah in 2026?

The average cost of an 8 kW solar system in Utah is approximately $24,000 ($3.00/watt installed). Note: The federal residential solar tax credit (Section 25D) was repealed in early 2026, so the full system cost applies unless state incentives are available. State-level incentives may reduce your out-of-pocket cost. Get 3-5 quotes from local installers for accurate pricing.

Is the federal solar tax credit available in Utah?

The federal residential solar tax credit (Section 25D) was repealed in early 2026. Homeowners who installed solar before the repeal can still claim the credit for that tax year. Commercial solar projects continue to receive the 30% ITC under Section 48/48E. Utah still offers state-level incentives that can reduce your solar costs. Consult a tax professional for the latest guidance.

How does Utah's climate affect solar panel efficiency?

Utah receives 5.6 peak sun hours/day, which is excellent for solar production. However, high temperatures can reduce panel efficiency. Choose panels with strong temperature coefficients (closer to 0%/°C) to minimize heat-related losses. An 8 kW system in Utah can produce approximately 2,126 in annual savings.

How much can I save with solar in Utah?

An 8 kW solar system in Utah produces approximately 16,352 kWh/year, saving about $2,126 annually. The estimated payback period is 11.3 years. Over 25 years, total savings can reach $53,150.

Does Utah have net metering?

Net metering policies vary by utility in Utah. Most states offer some form of net metering or net billing that credits solar homeowners for excess electricity sent back to the grid. Contact your local utility or check the DSIRE database for current Utah net metering policies.

What is the best solar panel for Utah?

For Utah's high-sun climate (5.6 hours/day), panels with excellent temperature coefficients perform best since they lose less power in heat. Look for HJT or high-quality TOPCon panels with temp coefficients closer to 0%/°C.

What is the payback period for solar in Utah?

The estimated payback period for an 8 kW solar system in Utah is 11.3 years. This is calculated as: system cost ($24,000) divided by annual savings ($2,126/year). After payback, solar generates essentially free electricity for 15-20+ more years. State incentives may shorten this further.

Do I need a battery for solar in Utah?

A battery is not required for grid-tied solar in Utah, but it provides backup power during outages and can increase savings with time-of-use rate optimization. Utah's incentive programs may include battery storage rebates.

Does Utah have solar incentives?

Yes, Utah offers state-level solar incentives. These may include state tax credits, rebates, property tax exemptions, sales tax exemptions, or SRECs. The federal residential ITC (Section 25D) was repealed in early 2026. Check the DSIRE database for current programs.
