Solar in Wyoming: Plenty of Sun, Not Much Support

Wyoming has some of the best solar resources in the country. High altitude, dry air, and wide-open skies mean panels produce more electricity per watt here than in most states east of the Mississippi. It also has some of the cheapest electricity and fewest solar incentives.

That combination creates an unusual situation — excellent production potential paired with weak economic motivation. Here is what Wyoming homeowners need to know in 2026.

The Good News

Excellent Solar Resource

Wyoming averages 5.0-5.8 peak sun hours per day, putting it in the top tier nationally. High altitude reduces atmospheric interference, and low humidity means fewer cloudy days. A solar panel in Cheyenne produces 15-25% more electricity annually than the same panel in Chicago or Atlanta.

Net Metering Available

Wyoming requires net metering for systems up to 25 kW through investor-owned utilities like Rocky Mountain Power (PacifiCorp) and Black Hills Energy. Excess generation is credited at the full retail rate and rolls over monthly. This is the single most important policy for making solar work in Wyoming.

Property Tax Exemption

Wyoming exempts the added value of renewable energy systems from property taxes for the first four years after installation. After four years, the system is assessed at its depreciated value. The first four years are the most impactful since that is when the system value is highest.

No State Income Tax

Wyoming has no state income tax. Like Washington and Texas, this means no state solar tax credit exists — but your overall tax burden is already lower.

The Challenges

Very Low Electricity Rates

This is the primary obstacle. Wyoming's average residential electricity rate is $0.10-$0.12/kWh — among the lowest in the nation. Cheap electricity means every kWh your panels produce saves you less money. The payback math suffers significantly compared to states with $0.15-$0.18/kWh rates.

Wyoming's low rates come from abundant coal and natural gas. Ironically, the fossil fuel resources that make Wyoming an energy powerhouse also make solar a harder economic case.

Zero State Incentives

No state tax credit. No rebate program. No SREC market. No sales tax exemption for solar equipment. Wyoming's 4% sales tax (plus local additions up to 6%) applies to your solar purchase. The state government offers essentially nothing to support residential solar adoption.

Wind, Not Solar, Is the State Priority

Wyoming is the windiest state in America and has invested heavily in wind energy. Solar policy has received almost no legislative attention. Do not expect state-level solar incentives to materialize anytime soon.

Small Installer Market

Wyoming's low population density and small solar market means fewer installers compete for your business. Less competition can mean higher per-watt prices. Getting three or more quotes may require including installers from Colorado or Montana.

The Wyoming Solar Math (2026)

Typical 8kW system:

• Installed cost: $27,200 ($3.40/watt — limited competition premium)
• Federal ITC: $0 (expired January 1, 2026)
• State credits: $0
• Sales tax exemption: None (4-6% applies)
• Net cost: ~$27,200

Annual production: ~11,600 kWh (Wyoming sun is strong)

Average rate: $0.11/kWh

Annual savings: $1,276

Payback period: ~21 years at flat rates, ~17 years with 4% annual rate increases

25-year savings: $10,000-$18,000

The production numbers are great. The savings per kWh are not. This is the fundamental tension of Wyoming solar.

When Solar Makes Sense

Install if:

• You value energy independence and self-sufficiency (a Wyoming value if there ever was one)
• Your property is remote and electricity reliability is a concern — a home battery like the Tesla Powerwall provides backup during outages
• You plan to stay 15+ years and expect electricity rates to rise
• You have a large south-facing roof with no shading
• You are willing to accept a longer payback for long-term savings

Wait or skip if:

• Financial payback within 10 years is your requirement
• Your electricity bill is under $80/month
• You plan to move within 10 years
• You are in a location with extreme wind exposure that could stress mounting hardware

Key Takeaways

• Wyoming has excellent sun — 5.0-5.8 peak sun hours, top tier nationally
• Low electricity rates ($0.10-$0.12/kWh) are the biggest obstacle to solar economics
• No state incentives of any kind and no federal ITC in 2026
• Net metering at retail rate is mandated and is the only meaningful policy support
• Property tax exemption covers the first four years post-installation
• Limited installer competition may mean higher per-watt costs — get quotes from neighboring states
• Typical payback: 17-21 years with 25-year savings of $10,000-$18,000
• Wyoming solar is a long-term self-sufficiency investment more than a quick financial play
