Utah Solar in 2026: The Honest Picture

Utah is one of the sunniest states in the nation, with an average solar irradiance of 5.2 kWh/m2/day. That puts Utah in the top tier for solar potential. However, the solar incentive landscape changed significantly in 2026. The federal Residential Clean Energy Credit (Section 25D) expired at the end of 2025, removing what was once the largest financial incentive for homeowners. Most Utah residents installing solar in 2026 will not qualify for a federal tax credit unless they pursue a third-party lease structure.

The good news: Utah has some of the strongest state-level solar incentives in the country. A 25% state income tax credit, full property tax exemption, sales tax exemption on equipment, and net metering through Rocky Mountain Power make solar financially viable even without federal support. For many Utah homeowners, the combination of state incentives, utility credits, and long-term electricity savings still justifies the investment.

This guide walks you through real costs, savings scenarios, available incentives, and what to look for in an installer.

Average Solar System Cost in Utah (2026)

A typical 6-kW residential solar system in Utah costs between $24,000 and $29,000 before incentives, with an average of $26,500. This breaks down to roughly $4.40 per watt after accounting for equipment, labor, permitting, and interconnection.

Cost factors specific to Utah:

  • Equipment costs: Panels and inverters represent 40-45% of the total. Utah’s remote location in some areas may add shipping costs, but competition among installers keeps prices competitive.
  • Labor: Installation labor typically runs $8,000 to $12,000 for a 6-kW system, depending on roof complexity and local wage rates.
  • Permitting and interconnection: Utah municipalities charge $500 to $1,500 for permits. Interconnection fees with Rocky Mountain Power or other utilities range from $200 to $800.
  • Sales tax: None. Utah exempts solar equipment from sales tax, saving homeowners roughly $1,600 to $2,000 on a typical system.

After applying Utah’s 25% state income tax credit (max $2,000), the net cost drops to approximately $24,500 to $27,500. For comparison, see EnergySage’s Utah solar cost benchmarks.

Real Utah Homeowner Savings (Sample Scenarios)

Savings depend on your location, electricity rates, system size, and available incentives. Here are five realistic scenarios for Utah homeowners:

Salt Lake City (Rocky Mountain Power, 6-kW system)

  • Annual electricity bill: $1,400
  • Annual solar production: 8,500 kWh
  • Annual savings: $1,020
  • 25-year lifetime savings: $28,500
  • Payback period: 9 years

Provo (Rocky Mountain Power, 5-kW system)

  • Annual electricity bill: $1,200
  • Annual solar production: 7,200 kWh
  • Annual savings: $864
  • 25-year lifetime savings: $24,100
  • Payback period: 10 years

St. George (Dominion Energy Utah, 6-kW system)

  • Annual electricity bill: $1,600
  • Annual solar production: 9,200 kWh
  • Annual savings: $1,104
  • 25-year lifetime savings: $30,800
  • Payback period: 8 years

Ogden (Rocky Mountain Power, 6-kW system)

  • Annual electricity bill: $1,350
  • Annual solar production: 8,300 kWh
  • Annual savings: $996
  • 25-year lifetime savings: $27,900
  • Payback period: 9 years

Cedar City (Dominion Energy Utah, 5-kW system)

  • Annual electricity bill: $1,100
  • Annual solar production: 8,000 kWh
  • Annual savings: $960
  • 25-year lifetime savings: $26,800
  • Payback period: 8 years

These estimates assume 2% annual electricity rate increases and do not include the state income tax credit, which would reduce payback by 1-2 years.

Utah Solar Incentives Still Available in 2026

State Income Tax Credit

Utah offers a 25% tax credit on the cost of a residential solar system, capped at $2,000 per system. The credit applies to systems installed on your primary residence and is claimed on your state income tax return. This is one of the strongest state incentives in the country and directly reduces your tax liability.

Example: A $26,500 system qualifies for a $2,000 credit (25% of cost, capped). This reduces your net cost to $24,500.

Property Tax Exemption

Utah exempts the entire assessed value of a residential solar system from property taxes. This means your property tax bill will not increase when you add solar, even though the system increases your home’s market value. This exemption is permanent and applies to all residential systems.

Sales Tax Exemption

Solar equipment, including panels, inverters, racking, and installation labor, is exempt from Utah sales tax. This saves homeowners 6-7% on the total system cost, or roughly $1,600 to $2,000 on a typical 6-kW system.

Net Metering (Rocky Mountain Power)

Rocky Mountain Power, which serves most of northern and central Utah, offers 1:1 net metering. Excess solar generation is credited to your account at the full retail electricity rate. These credits roll over month to month and are paid out annually if you have a surplus. This is a strong incentive for homeowners with systems sized to offset most or all of their annual consumption.

PacifiCorp and Dominion Energy Utah have more limited net metering policies. Check with your local utility for specifics.

Utility Rebates

Dominion Energy Utah offers a solar rebate of up to $1,500 per residential system. Eligibility and rebate amounts vary by service territory. Contact your utility directly for current programs.

For a comprehensive list of all available incentives, see the DSIRE database, which tracks state and local solar programs.

Federal Section 48E (Third-Party Lease Only)

The only federal incentive available in 2026 is the Investment Tax Credit (Section 48E) for third-party-owned solar leases. However, construction must have begun before July 4, 2026. Most homeowners purchasing systems outright in 2026 will not qualify. For details, see IRS Section 25D guidance.

Is Solar Worth It in Utah Without the Federal Credit?

Yes, for most homeowners. Utah’s state incentives, strong solar resource, and net metering through Rocky Mountain Power make solar financially sound even without the federal credit.

Payback analysis:

  • With state tax credit and property tax exemption: 8-10 years
  • Without federal credit but with state incentives: 9-12 years
  • System lifespan: 25-30 years

After payback, you generate free electricity for 15-20+ years. Over 25 years, the average Utah homeowner saves $28,000 to $32,000.

Break-even factors:

  • You own your home for at least 10 years (or plan to stay through payback).
  • Your roof has 15+ years of remaining life.
  • Your electricity rates are at or above the state average ($0.12 to $0.14 per kWh).
  • You can use the state tax credit (you owe at least $2,000 in state income tax).

If you rent, have a roof in poor condition, or plan to move within 8 years, solar may not be the right choice.

What to Look for in a Utah Solar Installer

  1. Licensing and insurance: Verify the installer holds a current Utah electrical contractor license and carries general liability and workers’ compensation insurance. Check the Utah Division of Occupational and Professional Licensing (DOPL) database.

  2. Experience with Rocky Mountain Power interconnection: Most Utah homeowners use Rocky Mountain Power. Choose an installer familiar with their net metering application process and timeline (typically 30-60 days).

  3. Familiarity with state tax credit: The installer should help you document the system cost and guide you through claiming the 25% state tax credit on your return.

  4. Warranty coverage: Expect 10-year workmanship warranties and 25-year panel warranties. Confirm the installer backs their work in writing.

  5. References and reviews: Ask for at least three local references and check Google, Yelp, and the Better Business Bureau. Look for installers with 4.5+ star ratings and no unresolved complaints.

  6. Transparent pricing: Get written quotes from at least three installers. Avoid vague estimates. The quote should itemize equipment, labor, permitting, and incentives.

  7. Monitoring and support: Confirm the system includes real-time monitoring (app or web portal) and that the installer provides ongoing technical support for at least five years.

Get Free Quotes From Vetted Utah Installers

The best way to compare costs and incentives is to request quotes from multiple installers. Most offer free consultations and site assessments. When you request quotes, ask each installer to:

  • Itemize the system cost and show the impact of the state tax credit.
  • Confirm net metering eligibility with your utility.
  • Provide a timeline for permitting and installation.
  • Explain their warranty and monitoring offerings.

Utah has a growing solar market with dozens of qualified installers. Comparing at least three quotes will help you find the best price and service for your home.
