Data current as of May 2026. Rates, incentives, and regulatory dockets are subject to change.
The federal residential solar credit ended in December 2025. That was the single largest financial offset available to Wyoming homeowners buying a system outright. Its loss exposed how narrow the state’s own support has been all along.
What follows explains the incentives that actually apply, how each one functions as a mechanism, and where the policy ground is shifting beneath them.

What Wyoming’s Solar Incentive Stack Actually Looks Like
Wyoming’s active solar incentives fit on a short list. Two are state-level, one is federal but available only through third-party ownership, and several others commonly cited online are either discontinued or unverifiable.
Incentive | Status | Estimated Value | Key Detail |
|---|---|---|---|
Sales-tax exemption (solar equipment) | Active | ~$1,100–$1,600 on typical system | Applied at point of sale; no application needed |
Net metering (W.S. § 37-16-101) | Active | Retail-rate kWh credit, ongoing | 25 kW cap; annual sweep at avoided cost |
Solar Rights statute (W.S. § 34-22-101) | Active | Legal protection only | Limits HOA prohibitions on solar installations |
Federal residential credit (Section 25D) | Terminated Dec 31, 2025 | Was 30% of system cost | Carryforward available for pre-2026 installs only |
Federal commercial credit (Section 48E) | Active for TPO only | 30% for the leasing company | Through Dec 2027; FEOC sourcing rules apply |
Property-tax exemption | ⚠️ Unverified | Unknown | Conflicting sources; not confirmed in primary law |
State solar rebate ($3,000 / 50% cap) | Discontinued | N/A | No administering agency |
The sales-tax exemption and net metering are the foundation. Everything else is gone, limited to third-party ownership structures, or unverifiable in primary law.
A homeowner searching online will find pages listing programs that no longer exist: a $3,000 state rebate with no administering agency, a property-tax exemption cited by several sources but not confirmed in Wyoming statute, and a federal credit described as if it were still active. Starting from verified facts matters more than repeating what’s expired.
The Federal Credit Ended: What That Means for Wyoming Homeowners
The federal residential clean energy credit under Section 25D of the Internal Revenue Code allowed homeowners to deduct 30% of their solar system cost from federal income taxes. The Inflation Reduction Act scheduled that credit to run through 2032. The One Big Beautiful Bill Act (Public Law 119-21, signed July 4, 2025) accelerated its termination to December 31, 2025.
Per IRS guidance, the operative trigger is installation completion. If your system was fully installed by that deadline, you can still claim the credit on your 2025 return using IRS Form 5695. Any unused credit from a qualifying 2025 installation carries forward to future tax years.
For systems installed in 2026 or later, the 30% residential credit no longer applies. In a state where no state-level credit existed to backstop the federal one, the loss is total for homeowners who buy or finance a system with a loan.
One pathway remains. Under Section 48E, the Clean Electricity Investment Credit, third-party system owners can still claim a 30% credit on qualifying systems. The solar company owns the equipment, claims the credit, and may reflect that value in lower monthly lease payments. This credit remains available for systems that begin construction by July 4, 2026, or are placed in service by December 31, 2027, subject to Foreign Entity of Concern sourcing rules.
How You Get Solar | Federal Credit Available? | Who Claims It | Key Deadline |
|---|---|---|---|
Cash purchase or loan | No (Section 25D terminated) | N/A | Expired Dec 31, 2025 |
Solar lease | Yes (Section 48E, 30%) | The leasing company | Construction start by Jul 4, 2026, or in service by Dec 31, 2027 |
Power purchase agreement | Technically yes, but PPAs lack legal authorization in WY | The PPA provider | Same as lease; carries regulatory risk |
If you are buying a system in Wyoming in 2026, your out-of-pocket cost is the full price. If you are leasing, some of the federal value may flow back to you through lower monthly payments. Understanding how zero-down solar programs work in Wyoming matters more now than when every buyer had direct access to 30%.
Wyoming’s Sales-Tax Exemption on Solar Equipment
Wyoming exempts solar energy equipment from the state’s sales tax. This applies to panels, inverters, racking, batteries, and related system components. The exemption traces to H.B. 319 (2007) and is confirmed by the Wyoming Legislative Service Office.
The exemption is applied at the point of sale. Your installer does not charge state sales tax on qualifying equipment, which reduces the upfront cost immediately.
On a typical 8 kW system priced at approximately $26,600 before incentives, the exemption saves roughly $1,100 to $1,600, depending on the equipment breakdown and how the state’s 4% rate applies. A system with battery storage would see additional savings on the battery hardware.
This incentive requires no application, has no funding cap, and does not expire under a competitive enrollment process. It is a standing tax policy.
With the federal credit gone, this exemption is Wyoming’s only mechanism that reduces what you pay at installation. It is real, but it is not 30% of a $26,600 system. Knowing what solar panels actually cost in Wyoming before incentives helps put the exemption’s value in its proper context.
How Wyoming’s Net Metering Law Works and Why It Matters More Now
If one policy determines whether solar pencils in Wyoming, it is net metering. The state statute (W.S. § 37-16-101 through § 37-16-104) requires electric utilities to offer net metering for customer-generators with systems up to 25 kW.
How the Credits Work
When your panels produce more electricity than your home uses within a billing period, the excess flows to the grid and earns a kilowatt-hour credit on your next bill. You pay only for the net difference. Credits roll forward month to month throughout the year.
At the beginning of each calendar year, any remaining unused kWh credits are purchased by the utility at its filed avoided cost. For Rocky Mountain Power, that tracks Schedule 37 QF rates: 1.16 ¢/kWh on-peak in winter, 3.62 ¢/kWh on-peak in summer. That is a fraction of the roughly 12 ¢/kWh retail rate you receive for in-month credits.
The practical lesson: size your system to match annual consumption, not to overproduce. Every kWh you offset within the month is worth retail. Every kWh that survives to the annual sweep is worth pennies.
The 25 kW System Cap
Wyoming’s statute defines a “net metering system” as one with generating capacity of not more than 25 kW. Systems above that threshold do not qualify and must use a QF/PURPA path at avoided cost, which is rarely attractive for residential customers.
Most residential installations fall well within this limit. A typical 8 kW system covers average household consumption of about 10,400 kWh per year with Wyoming’s strong solar resource.
Who Is Covered and Who Isn’t
The statute applies to investor-owned utilities and electric cooperatives. Municipal electric utilities are explicitly excluded. If your home is served by a municipal utility, you have no statutory net metering right. Very few Wyoming municipalities operate electric utilities, but confirm directly if you are unsure.
The sales-tax exemption reduces what you pay once. Net metering determines what your system earns you for the next 25 years. With the federal credit gone, net metering is the single most valuable policy protecting a Wyoming solar investment.
Net Metering by Utility: Where the Credit Rules Actually Vary
The statute sets the floor. What each utility charges and how it handles crediting in practice varies.
Utility | Credit Structure | Monthly Minimum | Regulatory Watch |
|---|---|---|---|
Rocky Mountain Power | Retail rate (12.175 ¢/kWh flat) | ~$24/mo basic charge | Rate case filed May 2026 (8.8% increase requested) |
Black Hills Energy (CLFP) | Retail rate | ~$16.50/mo service charge | DSM rebate program withdrawn; rate docket active |
Montana-Dakota Utilities | Retail rate (pre-revision) | Uncertain (rate case pending) | Docket 20004-179-ET-26: net metering rates under review |
Rural electric cooperatives | Varies; many credit at avoided cost | Varies by co-op | Not consolidated by WPSC; contact directly |
Municipal utilities | No statutory requirement | N/A | Excluded from net metering statute |
Rocky Mountain Power serves the largest share of Wyoming’s residential customers. The January 2026 tariff (P.S.C. Wyoming No. 19) sets a basic charge of $24.24 per month and a flat energy rate of 12.175 ¢/kWh under Schedule 2. An optional time-of-use pilot (Schedule 19) is available: 16.092 ¢/kWh on-peak, 9.870 ¢/kWh off-peak, with a $2.06/month metering fee.
Black Hills Energy (Cheyenne Light, Fuel & Power) serves the Cheyenne area under Tariff No. 13, with a service charge of approximately $16.50 per month. A 1,000 kWh bill runs in the mid-$160s before tax. The 2026 DSM rebate program was withdrawn.
Montana-Dakota Utilities serves northeastern Wyoming and has filed both a 24.36% retail rate increase (Docket 20004-174-GR-25) and a separate application to revise its net metering rates (Docket 20004-179-ET-26, filed March 2026). If the Commission approves a shift from retail-rate crediting to avoided-cost or net-billing, the long-term solar economics in MDU territory change significantly.
Your utility’s basic service charge of $16 to $24+ per month cannot be offset by solar. You will still pay that minimum regardless of how much your system produces.
Why Rising Utility Rates Change Wyoming’s Incentive Math
In a state with almost no upfront incentives, the value of solar depends on how much the electricity it replaces would have cost you.
Wyoming residential rates have climbed approximately 3.3% per year over the past five years, rising from 10.61 ¢/kWh in 2019 to 12.47 ¢/kWh in 2024. The most recent monthly snapshot (March 2026, EIA Table 5.6.A) shows 13.59 ¢/kWh, up from 12.41 ¢/kWh in March 2025.
Rocky Mountain Power announced a new general rate case on May 14, 2026, requesting an 8.8% increase. The prior case (Docket 20000-664-EM-24) settled at 16.2% overall. Multiple rider schedules reset annually, adding rate volatility on top of base-rate increases.
Each rate increase makes every kWh your system produces worth more. An 8 kW system generating roughly 13,200 kWh per year at today’s RMP rate offsets about $1,600 in annual electricity cost. If rates continue rising at 3% per year, that same production offsets approximately $2,150 per year by year 10 and $2,900 per year by year 20.
The rate trajectory is Wyoming’s strongest incentive. It is not a program you apply for. It is the economic reality that makes the remaining mechanisms worth having. For a broader look at how rates, incentives, and system cost combine, see our analysis of whether solar panels are worth the investment in Wyoming.
Policy Risks Wyoming Solar Buyers Should Understand
Wyoming’s two main incentive mechanisms are statutory, which provides some stability. The pressure on both is real and current.
Net metering is the primary target. The Wyoming Outdoor Council documented 2024–2025 legislative attempts to end retail-rate net metering for new system owners by July 2025 and for existing owners by 2030. Those bills failed, but they established the direction of the debate. MDU’s Docket 20004-179-ET-26 proposes revising its net metering tariff. If the Commission approves a shift from retail-rate crediting to avoided-cost or net-billing, new customers in MDU territory face a materially different economic picture.
PPAs lack legal authorization. Wyoming is not on the DSIRE list of states that have affirmatively authorized residential third-party power purchase agreements. A third party selling electricity to a Wyoming homeowner could be classified as a “public utility” under W.S. § 37-1-101. Solar leases are legal and available through national providers. PPAs are a different structure and carry regulatory risk.
The sales-tax exemption’s precise current sunset should be verified. The exemption traces to 2007 legislation. Its current statutory cite and any sunset provision should be confirmed with the Wyoming Department of Revenue before it becomes a factor in a purchasing decision.
An incentive that exists today is only as valuable as the likelihood it will still exist when your system needs it. If you are evaluating solar in MDU territory, factor in the possibility that net metering compensation could change before your system pays back.
When Wyoming’s Solar Incentives Won’t Reach You
Not every Wyoming homeowner will benefit from the incentives described above. Saying so plainly is more useful than pretending the math works everywhere.
You’re on a rural cooperative with avoided-cost crediting. Several Wyoming co-ops credit excess generation at their avoided cost, not retail. If your bundled rate is below about 9 ¢/kWh, the offset value is minimal and payback stretches past 18 years.
Your consumption is under 6,000 kWh per year. Fixed monthly charges of $20 to $33+ cannot be solar-offset. Below roughly 500 kWh per month, the energy charge portion of your bill is too small to justify a system.
Your only available roof plane faces north. At Wyoming’s latitude, a north-facing array loses 30% to 45% of output compared to south-facing. Combined with snow load, the production rarely supports the investment.
You plan to sell within five years. Wyoming’s low rates and the absence of a federal credit mean payback runs 12 to 18 years for most owned systems. A short hold cannot recover the upfront cost, even with a documented home-value premium.
You’re in the I-80 high-wind corridor. Sites along Cheyenne, Laramie, Rawlins, Rock Springs, and Elk Mountain carry ASCE 7 basic design wind speeds of 115 to 130 mph. The additional structural engineering pushes installed cost above the statewide average and can extend payback past 15 years.
Your utility is actively revising net metering. MDU’s Docket 20004-179-ET-26 could move compensation below retail. New customers in that territory should expect the credit structure they sign up for to potentially change within a few years.

Frequently Asked Questions
No. Wyoming has no personal income tax, which means no state-level solar tax credit is possible. The state’s support comes through a sales-tax exemption on solar equipment and a statutory net metering law. These two mechanisms are the only state-level financial benefits currently in effect.
Not for homeowner-owned systems installed after December 31, 2025. The 30% residential credit (Section 25D) was terminated by the One Big Beautiful Bill Act. Third-party-owned systems (leases) can still access a 30% commercial credit under Section 48E through 2027, but the solar company claims that credit, not the homeowner.
Under W.S. § 37-16-101, utilities must offer net metering for systems up to 25 kW. Excess electricity you generate in a billing month earns a kilowatt-hour credit at your retail rate. Credits roll forward monthly. At the start of each calendar year, unused credits are purchased by the utility at its filed avoided cost, which is significantly lower than retail.
All investor-owned utilities and electric cooperatives are covered by the state statute. Municipal electric utilities are excluded. If your home is served by a municipal utility, there is no statutory net metering right. Co-op credit rates and terms vary and are not consolidated by the Wyoming Public Service Commission.
This is genuinely uncertain. Multiple secondary sources claim a residential solar property-tax exemption took effect in April 2022. ConsumerAffairs directly contradicts the claim. No primary Wyoming statute supporting it has been identified. Do not rely on this exemption without confirming it with the Wyoming Department of Revenue Property Tax Division.
Wyoming has not affirmatively authorized residential power purchase agreements. A third party selling electricity to a homeowner could be classified as a public utility under W.S. § 37-1-101. Solar leases are legal and available. PPAs carry regulatory risk in Wyoming, and buyers should understand the distinction before signing any agreement.
Unused kilowatt-hour credits remaining at the start of a new calendar year are purchased by the utility at its filed avoided cost. For Rocky Mountain Power, that rate runs approximately 1 to 4 ¢/kWh depending on season. This is why systems should be sized to match annual consumption, not to overproduce.
Without the federal credit, a cash-purchased 8 kW system at approximately $26,600 has an estimated payback period of 12 to 18 years, depending on your utility’s rate, your consumption, and how quickly rates rise. Estimated 25-year net savings range from roughly $6,000 to $14,000 for an owned system.
Yes. National providers such as Sunrun and Sunnova offer solar leases through installer networks. The leasing company owns the system, claims the Section 48E credit (through 2027), and may pass some of that value to you through lower monthly payments. Watch for annual escalator clauses: a 2.9% to 3.9% annual escalator can erode savings against Wyoming’s historically moderate rate growth of about 3.3% per year.
No. Wyoming has no renewable portfolio standard and no SREC market. You cannot generate additional income by selling renewable energy certificates from a residential system.
