Data current as of May 2026. Federal incentive information reflects the One Big Beautiful Bill Act, signed July 4, 2025.
Wyoming homeowners pay some of the lowest electricity rates in the country. That has kept solar off most people’s radar for years. Rocky Mountain Power’s residential rates have climbed 3.3% annually since 2019, though, and the utility just filed for another 8.8% increase in May 2026. Montana-Dakota Utilities requested 24.36% the year before.
The federal 30% residential solar credit is gone. No state rebate exists. Solar in Wyoming comes down to one question: does locking in your electricity cost now, while the grid gets more expensive every year, justify a $24,000 to $29,000 commitment that takes 12 to 18 years to pay back?
What an 8 kW System Actually Costs in Wyoming
A properly sized residential system in Wyoming runs about $3.33 per watt installed before incentives. That figure comes from Wyoming-specific marketplace data as of May 2026, not a national average.
The average Wyoming home uses 863 kWh per month. At 5.5 to 5.7 peak sun hours per day, an 8 kW system produces about 13,200 kWh per year, more than enough to cover that usage. Wyoming’s high altitude and cold, clear air boost panel efficiency compared to hotter states.
System Size | Solar Only (Before Incentives) | Solar Plus Battery | Best Fit |
|---|---|---|---|
6 kW | $18,000 to $22,000 | $32,000 to $38,000 | Smaller home or partial offset |
8 kW | $24,000 to $29,000 | $38,000 to $45,000 | Average Wyoming home (863 kWh/mo) |
10 kW | $30,000 to $36,000 | $44,000 to $52,000 | Higher usage or all-electric home |
12 kW | $36,000 to $43,000 | $50,000 to $59,000 | Large home, EV, or shop |
Costs based on $3.33/W installed with a range reflecting real installer-to-installer variation in Wyoming. Battery figures add a 13.5 kWh system at $1,000 to $1,200/kWh. Actual quotes vary by roof type, equipment, and location within the state.
Those numbers are higher per watt than what you would see in Arizona or Texas. The reasons are specific to Wyoming’s geography and market.
Why Solar Pricing Runs Higher Along the I-80 Corridor
Wind-load engineering is the biggest driver. The I-80 corridor from Cheyenne through Laramie, Rawlins, and Rock Springs carries ASCE 7 basic design wind speeds of 115 to 130 mph, among the highest in the lower 48. Racking that meets those standards requires additional attachment points, upgraded hardware, and more labor. Panels and mounts designed for calmer states will not pass inspection here.
Few installers serve the state. Solar marketplaces list only two active installers in Wyoming. The main local company, Creative Energies, operates from offices in Lander and Laramie. Most other quotes come from installers based in Salt Lake City or Bozeman, Montana. Travel distance gets built into the price.
Snow load adds cost in the mountains. Jackson, Pinedale, and Star Valley require ground snow loads of 50 to 100+ pounds per square foot. Racking sized for those conditions is heavier and more expensive than what a Cheyenne or Casper install needs.
What pulls the price down? Wyoming’s labor and overhead costs run lower than in coastal markets. The state charges no sales tax on solar equipment. The solar resource itself, at 5.5 to 5.7 peak sun hours per day, means you can size a smaller system here to produce the same annual output. Higher hardware costs, lower soft costs, and a per-watt price above the national average but below the Northeast.
The Federal Credit Is Gone for Wyoming Homebuyers
The One Big Beautiful Bill Act, signed July 4, 2025, terminated the 30% Residential Clean Energy Credit (Section 25D) for any system installed after December 31, 2025. If you are buying solar with cash or a loan in 2026, there is no federal tax credit.
The IRS has confirmed the rule: if installation is completed after December 31, 2025, the homeowner cannot claim the credit. Installation completion is what matters, not the contract date. The Congressional Research Service analysis reached the same conclusion.
Wyoming has no state income tax, so there was never a state solar credit to begin with. In most other states, homeowners lost one credit. Wyoming buyers lost the only one that ever existed.
One option for federal value remains. If you go solar through a lease, the company that owns the system can claim the 30% commercial Investment Tax Credit under Section 48E, active through 2027. They pass some of that savings to you through lower monthly payments.
Without the credit, the entire system cost must be repaid through utility bill savings. That is why the rate trajectory matters more in Wyoming than in any incentive-heavy state.

What Wyoming Actually Offers in 2026
The state incentive stack is short. Here is what exists, what is gone, and what online sources get wrong:
Incentive | Type | 2026 Status | Estimated Value |
|---|---|---|---|
Equipment sales-tax exemption | State exemption | Active | About $1,300 to $1,600 on a typical system |
Net metering (W.S. § 37-16-101) | Utility bill credit | Active (statutory) | About $1,200 to $1,300/yr in avoided bills (RMP) |
Property-tax exemption | Claimed by third-party sites | Unverified in primary law | Unknown |
Section 25D (federal, 30%) | Residential tax credit | Terminated (Dec 31, 2025) | $0 |
Section 48E (federal, 30%) | Commercial tax credit | Active (lease only) | Varies via lease pricing |
State solar rebate ($3,000 cap) | Legacy rebate | Defunct | $0 |
The sales-tax exemption is real. Wyoming exempts solar equipment from the state sales tax. On a $26,600 system, that saves $1,300 to $1,600 at purchase. Your installer should reflect this in the quote.
Net metering is the real incentive. Under W.S. § 37-16-101 through 104, your utility credits you at the full retail rate for every kilowatt-hour your system sends to the grid within a billing month. On a Rocky Mountain Power bill, that monthly offset is the mechanism that makes the math work at all.
The property-tax exemption is unverified. Several websites claim Wyoming exempts solar from property taxes. ConsumerAffairs explicitly contradicts this. No primary statute or Department of Revenue guidance confirms the exemption. Do not count on it until you verify directly with the Wyoming Department of Revenue.
No RPS, no SREC market, no state rebate. Wyoming has no renewable portfolio standard, so there is no SREC income. The legacy $3,000 state rebate is defunct with no administering authority.

How Net Metering Works Under Wyoming’s Statute
Net metering is the single most valuable solar policy in Wyoming. Understanding exactly how it works, and where it falls short, is what separates a good decision from a bad one here.
The Wyoming net metering statute applies to investor-owned utilities and electric cooperatives. It covers systems up to 25 kW, well above any residential size.
Within each billing month, your utility measures the net flow between your system and the grid. If your panels produce more than you use, the excess carries forward as a kilowatt-hour credit at the full retail rate. No check. A credit on your next bill.
At the start of each calendar year, any remaining unused credits are purchased by the utility at its filed avoided cost. For Rocky Mountain Power, that avoided cost runs 1.16¢/kWh in winter and 3.62¢/kWh in summer under Schedule 37. That is a fraction of the 12.175¢/kWh retail rate. Size your system to match your actual consumption as closely as possible. Any large surplus that rolls to the annual sweep loses most of its value.
Municipal utility customers are excluded. The statute expressly excludes municipalities from the “electrical company” definition. If your power comes from a municipal electric utility, you have no statutory net-metering right.
The policy is under pressure. The Wyoming Outdoor Council documented 2024-2025 legislative attempts to end retail-rate net metering for new customers by July 2025 and for existing customers by 2030. Those bills failed. MDU has since filed Docket 20004-179-ET-26 to revise its net metering tariff. Your current terms are governed by your interconnection agreement, but there is no explicit statutory grandfather provision protecting them.
What Payback Looks Like on a Rocky Mountain Power Bill
Most Wyoming solar customers are on Rocky Mountain Power’s Schedule 2: $24.24 per month basic charge plus 12.175¢/kWh flat energy rate, effective January 1, 2026.
Here is the payback math for an 8 kW purchased system on that rate:
Line Item | Figure | Notes |
|---|---|---|
Gross system cost | About $26,600 | 8 kW at $3.33/W, before incentives |
Sales-tax exemption | About minus $1,400 | Applied at purchase |
Net cost after incentives | About $25,200 | No federal credit, no state rebate |
Annual bill offset (Year 1) | About $1,200 to $1,300/yr | 10,356 kWh/yr at $0.12175, net of annual avoided-cost sweep |
Basic charge (not offset) | $291/yr | $24.24/mo stays regardless of solar |
Payback at 3 to 4%/yr rate growth | About 12 to 15 years | Supported by RMP’s 3.3% CAGR and 8.8% new filing |
Payback at 2%/yr rate growth | About 16 to 18 years | Conservative scenario |
Value, years 16 to 25 | About $15,000 to $25,000+ | Avoided cost of rising electricity over remaining panel life |
The payback depends almost entirely on how fast rates rise. At the historical 3.3% annual increase, payback falls in the 13 to 15 year range. If RMP’s 8.8% filing succeeds and the pattern holds, it could be closer to 12. At a conservative 2% assumption, payback stretches past 16 years.
That is a longer wait than in high-rate states like Massachusetts or California, where systems pay back in 6 to 9 years. Wyoming solar is a 25-year investment, not a 5-year win. The value is real, but it is back-loaded. Years 1 through 12 are repayment. Years 13 through 25 are where the savings accumulate.
Your basic charge ($24.24/month, $291/year) cannot be offset by solar. That bill stays regardless.

How to Pay for Solar in Wyoming Without a Federal Credit
The 25D termination has reshaped how Wyoming homeowners finance solar.
Cash purchase still delivers the best long-term return. You own the system, keep every dollar of net-metering savings, and pay no interest. The downside: $24,000 to $29,000 out of pocket with no credit to soften the cost. For homeowners who plan to stay 15 years or more, cash is the strongest option.
Solar loans are available through Credit Human (referred by Creative Energies) and national platforms like GoodLeap and Mosaic. Without the 25D credit to make a lump-sum payment against the balance in Year 1, your monthly payment is higher than pre-2026 projections. Make sure the loan payment is genuinely lower than your current electricity bill before signing.
Leases are the only way to capture a federal credit in 2026. The leasing company claims the Section 48E commercial ITC (30%) and passes some of that value to you through lower monthly payments. You do not own the system or build equity, but your monthly cost should be lower than your current utility bill from day one.
Power purchase agreements are legally uncertain in Wyoming. Wyoming is not on the list of states that have authorized residential third-party PPAs. A third party selling electricity to a Wyoming homeowner could be classified as a “public utility” under W.S. § 37-1-101. Loans and leases are the safer options.
Watch for misleading “$0-down” marketing. A leased system is never free. The lessor recovers cost through 20 to 25 years of payments. Escalator clauses of 2.9% to 3.9% per year can erase savings against Wyoming’s lower-than-average utility rates. Verify production assumptions against NREL PVWatts before signing.

When the Rate-Hedging Math Fails in Wyoming
Solar does not make financial sense for every Wyoming home. Here are the specific situations where the numbers fall apart.
Your utility is a low-rate cooperative. Wyoming has 10 rural electric cooperatives, including High West Energy, Carbon Power & Light, Wheatland REA, and Bridger Valley Electric. Many charge bundled rates below 9¢/kWh and credit excess generation at avoided cost, not retail. At those rates, the annual savings are too small to recover the system cost in a reasonable timeframe.
Your consumption is below 500 kWh per month. Fixed basic charges from RMP, CLFP, and MDU run $20 to $33 per month and cannot be offset by solar. Below about 6,000 kWh per year, there is not enough energy cost to work with.
You plan to sell within five years. Solar adds home value, but in Wyoming’s low-rate market, the resale premium may not cover your remaining balance if you are financing. The payback math requires a hold period of at least 12 years.
Your roof faces north. At Wyoming’s latitude, north-facing planes lose 30% to 45% of production compared to south-facing. Combined with snow accumulation, north-mounted panels rarely pay back.
You are in the I-80 wind corridor without the engineering budget. Sites near Rawlins, Arlington, and Elk Mountain face ASCE 7 wind speeds that require structural upgrades. If the added cost pushes total installation past $4.00 per watt, the payback timeline extends past the useful life of the equipment.
Your utility is MDU with active rate proceedings. MDU’s Docket 20004-179-ET-26 is seeking to revise its net metering tariff. If avoided-cost crediting replaces retail, the solar value for MDU customers could weaken significantly.
What to Ask a Wyoming Installer Before You Sign
The Wyoming solar market is small. Fewer options means higher vetting stakes. Before signing, ask:
- Can you show ASCE 7 wind-load compliance for my county’s design speed? Any I-80 corridor install requires this. If the installer cannot produce the engineering calculations, they should not be on your roof.
- Do you hold a license from the Wyoming Department of Fire Prevention and Electrical Safety? Wyoming has no statewide solar-specific license, but electrical work on a PV system must be performed by a licensed electrician. Verify this directly.
- Are you NABCEP-certified? Jackson and Teton County require NABCEP certification for solar installers. Even outside Teton, NABCEP certification is the strongest independent quality marker in the industry.
- What is your workmanship warranty, and who services it in five years? In remote Wyoming counties, an installer based in Salt Lake City may not provide timely warranty service. Ask where the nearest service crew is.
- Will you size the system to stay under 25 kW? Systems above 25 kW fall outside Wyoming’s net metering statute and must use a far less favorable PURPA/QF tariff.

Frequently Asked Questions
An 8 kW system, which covers the average Wyoming home, costs $24,000 to $29,000 before incentives at $3.33 per watt installed. The state sales-tax exemption saves $1,300 to $1,600, but there is no federal credit for purchased systems in 2026.
No. The Section 25D residential credit was terminated for systems installed after December 31, 2025. Wyoming has no state income tax, so no state credit exists either. The only federal credit remaining (Section 48E) is available to leasing companies, not to homeowners who buy.
For a purchased system on Rocky Mountain Power, payback runs 12 to 18 years depending on how fast electricity rates rise. At the historical 3.3% annual growth rate, payback is closer to 13 to 15 years. The value is back-loaded: years 15 to 25 are when the real savings accumulate.
Yes. Under W.S. § 37-16-101, investor-owned utilities and cooperatives must credit excess solar production at the full retail rate within each billing month. Unused credits at year-end are purchased at the utility’s avoided cost, which is much lower: 1 to 4¢/kWh for RMP. Municipal utility customers are excluded.
Yes. Solar leases are legal and available through national providers. The leasing company claims the Section 48E commercial credit (30%) and passes some value to you through lower payments. Power purchase agreements are legally uncertain in Wyoming and should be approached with caution.
It depends on your rate, your usage, and how long you plan to stay. For RMP customers paying 12¢/kWh and rising, solar is a long-term rate hedge that delivers real value over 25 years. For co-op customers below 9¢/kWh or homes using less than 500 kWh per month, the math does not work.
Cold temperatures improve panel efficiency. Snow is the main concern: accumulated snow blocks production until it clears. A properly pitched system with appropriate racking sheds snow quickly. Any production estimate that ignores seasonal snow cover is too optimistic.
This is disputed. Several websites claim Wyoming exempts solar from property taxes, but no primary statute or Department of Revenue guidance confirms it. Do not rely on this exemption until you have verified it directly with the Wyoming Department of Revenue.
