A statewide residential electricity rate of 12.47 ¢/kWh puts Wyoming among the cheapest-power states in the country. The 30% federal residential solar credit ended for any system installed after December 31, 2025.
The state incentive stack is thin: a sales-tax exemption on equipment, statutory net metering, and little else. For a typical 8-kW system, that means paying about $26,600 out of pocket with no federal offset.
For a specific group of homeowners, solar still makes financial sense in Wyoming. For most, it does not yet.

Wyoming’s Rate Reality: Low Today, Climbing Fast
Wyoming’s residential electricity costs sit among the 10 lowest in the nation. That single fact is the biggest reason solar payback runs longer here than in most states. Each kilowatt-hour your panels produce offsets less dollar value than it would in Colorado, Montana, or nearly any coastal state.
The rate is low. The trend is not. Over the past five years, Wyoming residential prices have risen from 10.61 ¢/kWh to 12.47 ¢/kWh, a compound annual growth of about 3.3%. That growth is driven by utility rate cases, not inflation, and the filings keep coming.
Rocky Mountain Power, the state’s dominant utility, illustrates why. RMP’s residential Schedule 2 charges a combined $24.24 per month in basic and rider fees, plus 12.175 ¢/kWh flat for energy. The prior general rate case settled at 16.2%. A new filing from May 2026 seeks 8.8% more, with five rider schedules updating annually on top of the base.
Cheyenne Light, Fuel & Power (Black Hills Energy) customers face a similar pattern. WPSC rate-comparison data shows a 1,000-kWh monthly bill in the mid-$160s. Montana-Dakota Utilities, serving northeast Wyoming, filed a 24.36% rate increase in 2025 and a March 2026 application to revise its net metering tariffs.
The question for a Wyoming homeowner considering solar is not what electricity costs right now. It is what electricity will cost in year 8, year 12, and year 20 of a system that produces power for 25 years. If rate-case-driven increases of 3% per year continue, someone paying 12 ¢/kWh today could be paying 16 to 17 ¢/kWh within a decade. A solar system locks in a portion of your energy cost the day it turns on.
What Solar Costs in Wyoming Without the Federal Credit
A typical 8-kW rooftop system in Wyoming runs about $26,600 before incentives, based on Wyoming-specific marketplace data showing an installed cost of $3.33 per watt. National lab and industry sources do not publish a Wyoming-specific median because the state’s installation volume falls below their reporting thresholds.
Here is what the cost looks like across residential system sizes:
System Size | Solar Only | Solar + 13.5 kWh Battery |
|---|---|---|
6 kW | $18,000–$22,000 | $32,000–$38,000 |
8 kW | $24,000–$29,000 | $38,000–$45,000 |
10 kW | $30,000–$36,000 | $44,000–$52,000 |
12 kW | $36,000–$43,000 | $50,000–$59,000 |
Until December 2025, a homeowner who purchased a system could claim the 30% Section 25D Residential Clean Energy Credit. The One Big Beautiful Bill Act eliminated that credit for any system where installation was completed after December 31, 2025. For a $26,600 system, that is about $8,000 in lost value.
Wyoming’s remaining incentives do not fill the gap. The state exempts solar equipment from sales tax, which saves several hundred dollars on hardware. Statutory net metering (covered below) provides ongoing bill credit. There is no state income tax and therefore no state solar credit. No active state rebate program exists. A property-tax exemption is claimed by several online sources, but no primary Wyoming statute confirms it.
For a deeper look at what a full solar installation costs in Wyoming today, see our cost guide.
The result: Wyoming homeowners buying a system with cash in 2026 face the full sticker price. Payback depends on how much electricity the system offsets, how fast rates rise, and how long you plan to stay.
When Solar Is Worth It in Wyoming
Solar makes financial sense in Wyoming under specific conditions. The common thread is high consumption, a long time horizon, and a utility that charges enough per kilowatt-hour for the offset to matter.
Situation | Why It Works in Wyoming | What It Means in Practice |
|---|---|---|
High electricity bills on RMP or CLFP ($130+/month) | More grid power replaced at 12+ ¢/kWh means faster value accumulation, and rate-case increases compound the savings each year | An 8–10 kW system can offset most of the energy charge; payback runs 10–13 years for high-consumption homes |
Planning to stay in the home 10+ years | Wyoming’s payback is longer than most states, so the benefit builds in the second decade, not the first | A system purchased with cash can deliver $6,000–$14,000 in net savings over 25 years |
Buying with cash or a low-rate loan | No interest payments eating into the offset; full ownership of net-metering credits and any future resale value | Cash purchase yields the shortest payback; loans work if the monthly payment stays below the electricity savings |
South-facing roof, low shading, outside the I-80 wind corridor | Standard racking and engineering; no wind-load premium; strong production at Wyoming’s 5.5+ peak sun hours | System cost stays near the $3.33/W baseline; annual production runs about 1,650 kWh per installed kW |
The strongest case in Wyoming is a homeowner on Rocky Mountain Power or CLFP with monthly bills above $130, a roof in good condition, and no plans to sell for at least a decade.
The rising-rate math is what tips the balance: $26,600 is a large upfront cost, but if RMP’s rate trajectory holds, the system pays for itself before year 13 and produces electricity at no additional cost for another 12+ years under warranty.
When Solar May Not Be Worth It in Wyoming
Solar does not make financial sense for a large share of Wyoming homeowners. The reasons are specific to this state, and acknowledging them up front is more useful than a vague “it depends.”
Situation | Why It’s a Problem in Wyoming | What to Consider Instead |
|---|---|---|
Monthly bill under $80 (below ~600 kWh/month) | Low consumption means less grid power to offset; RMP’s $24/month basic charge cannot be solar-eliminated | Energy-efficiency upgrades first; revisit solar if consumption rises |
Served by a rural co-op with avoided-cost crediting | Many Wyoming co-ops credit excess at wholesale, not retail; bundled rates fall below 9 ¢/kWh | Check your co-op’s specific net-metering terms before assuming retail-rate value |
Planning to sell within 5 years | Wyoming’s longer payback leaves too little time to recover the investment, even with a home-sale premium | A solar lease with transfer provisions, or waiting until the next home |
Home on the I-80 high-wind corridor (Cheyenne to Rock Springs) | ASCE 7 design wind speeds of 115–130 mph require upgraded racking, adding $2,000–$5,000+ to install cost | Get a wind-engineering assessment before signing; ground-mount may be more cost-effective |
Only a north-facing roof plane available | Wyoming’s latitude means north-facing panels lose 30–45% of production versus south-facing | A ground-mount system if the property allows; otherwise, solar is unlikely to pay back |
Municipal electric utility customer | Wyoming’s net-metering statute does not apply to municipal utilities; no guaranteed credit rate | Verify your municipal utility’s solar policy directly before assuming any savings |
Wyoming’s rural co-op territories cover large portions of the state, the I-80 corridor runs through the most populated southern tier, and many homes outside Cheyenne and Casper have monthly bills well under $100. For these homeowners, skipping solar or delaying the decision is the financially sound call.
How You Pay Changes Whether Wyoming Solar Works
The financing method does not just change the monthly payment. In Wyoming’s low-rate environment, it changes whether solar is worth doing at all.
Option | What Happens in Wyoming | Who It Works For |
|---|---|---|
Cash purchase | You own the system, keep all net-metering credits, and face the longest payback (10–13+ years for high-consumption homes) with no interest cost | Homeowners with available capital and a 10+ year time horizon |
Solar loan | Monthly loan payments may exceed the electricity savings in early years; the math works only if the payment stays close to your current bill reduction | Homeowners with strong credit (680+ FICO) who want ownership without upfront cash |
Solar lease | The leasing company owns the system, claims the Section 48E commercial credit (active through 2027 for TPO), and passes some value through lower payments; you pay less but build no equity | Homeowners who want lower risk and no upfront cost, and accept smaller long-term savings |
PPA | Legally uncertain in Wyoming: the state has not authorized residential PPAs, and a third-party electricity seller risks “public utility” classification under W.S. § 37-1-101 | Approach any PPA offer with caution; demand the legal basis in writing and prefer a lease instead |
The lease path deserves a closer look in 2026. With the residential Section 25D credit gone, leases from third-party owners are the only remaining way for a Wyoming homeowner to indirectly benefit from a federal credit. The solar company claims the Section 48E Clean Electricity Investment Credit and prices it into the lease payment.
The tradeoff is real: you pay less upfront but own nothing, and escalator clauses of 2.9% to 3.9% per year can erode savings over time.

What Wyoming’s Net Metering Rules Mean for Your Savings
Wyoming’s net-metering statute (W.S. § 37-16-101 through 37-16-104) is the state’s single most valuable solar policy. It requires investor-owned utilities and electric cooperatives to offer net metering for systems up to 25 kW.
The mechanics matter. Within each billing month, any electricity your system produces beyond what your home uses rolls forward as a kilowatt-for-kilowatt credit at the full retail rate. That credit offsets future consumption one-for-one. At the start of each calendar year, any remaining unused credit is purchased by the utility at its filed avoided cost, not at retail.
The avoided-cost rate is where the real math lives. Rocky Mountain Power’s Schedule 37 wind QF prices run 1.16 ¢/kWh on-peak in winter and 3.62 ¢/kWh on-peak in summer. A system that produces more than the home uses in a given month carries that excess at retail for the rest of the year, but any balance left in January drops to a few cents per kilowatt-hour. Right-sizing the system to match annual consumption, rather than exceed it, matters more in Wyoming than in states with year-round retail crediting.
Municipal utility customers have no statutory net-metering right. The statute explicitly excludes municipalities from its definition of “electrical company.” Few Wyoming municipalities operate their own electric utilities, but if yours does, verify its solar policy directly.
The policy is also not guaranteed to last. The Wyoming Outdoor Council documented 2024 legislative attempts to end retail-rate net metering for new systems by July 2025 and for existing systems by 2030. Those efforts failed, but Montana-Dakota Utilities has filed Docket 20004-179-ET-26 to revise its net metering tariff. Existing interconnection agreements provide some protection, though the statute includes no explicit grandfather clause.

How to Tell If Solar Fits Your Wyoming Home
Every factor below you can check yourself, before requesting a single quote.
What is your monthly electricity bill? The threshold in Wyoming is higher than in most states. Homes spending $130 or more per month on RMP or CLFP tend to see the clearest returns. Below $80, the offset value is too small for the system to pay back within a reasonable time frame.
Which utility serves your home? RMP and CLFP customers benefit from full-retail net metering and a clear rate-escalation trend. Co-op customers should check their specific tariff: many credit excess at avoided cost, which cuts the savings significantly. Municipal utility customers need to verify their provider’s terms directly.
How long do you plan to stay? Payback in Wyoming runs 10 to 13 years for the strongest cases. If you may sell in fewer than 7 years, the financial return is unlikely to justify the upfront cost. A lease with transfer provisions may fit better, or it may make sense to wait.
How old is your roof? Wyoming insurers commonly require roofs under 15 years old to bind policies covering solar installations. If a roof replacement is already planned, bundling solar with it reduces disruption and may improve the timing.
Are you in the I-80 wind corridor? Homes between Cheyenne and Rock Springs face ASCE 7 design wind speeds of 115 to 130 mph. Racking upgrades and additional labor can add thousands to the install cost. A local installer with high-wind experience is essential for an accurate quote.
What direction does your usable roof face? South-facing planes perform best at Wyoming’s latitude. West-facing is workable. North-facing roofs lose 30 to 45% of potential output and rarely justify the investment.
What to Look for in a Wyoming Installer
Wyoming has few active solar installers. Online marketplace platforms list only two active installers in the state. The dominant local company is Creative Energies, a Certified B-Corp with offices in Lander and Laramie, operating since 2000 and named the state’s top solar contractor by Solar Power World.
National providers including Sunrun, Sunnova, Palmetto, and Tesla Energy supply some inventory through lease and loan programs. Availability varies by county, and response times for warranty service in remote areas can be longer.
Wyoming does not have a statewide solar-specific contractor license. Electrical work on a PV system must be performed by or supervised by a licensee of the Wyoming Department of Fire Prevention and Electrical Safety. The Town of Jackson and Teton County uniquely require NABCEP certification (or an equivalent approved by the Building Official) for solar specialty installers.
What to verify before signing:
- Electrical license from the Wyoming Department of Fire Prevention and Electrical Safety
- Wind-load engineering credentials if your site sees design wind speeds above 110 mph
- Workmanship warranty length: Creative Energies and a few peers offer 10 to 25 years; smaller firms may cover only 5 to 10
- Service-network density: ask where the nearest service crew is based, especially in remote counties
- Net-metering expertise: confirm the installer handles the interconnection application and understands Wyoming’s annual avoided-cost sweep

The Wyoming Verdict: A Narrow Yes, an Honest No
Solar can work in Wyoming. The conditions are specific: high electricity consumption, a utility subject to ongoing rate-case pressure (RMP, CLFP, or MDU), a time horizon of 10 years or longer, and a cash or low-interest-loan purchase. For that group, an 8-kW system at current prices can deliver $6,000 to $14,000 in net savings over 25 years, with most of the value accumulating after the payback period as rate escalation widens the gap between grid cost and solar-generated cost.
For homeowners with monthly bills under $80, co-op service at avoided-cost crediting, plans to move within five years, or sites requiring high-wind engineering, solar in 2026 is not the right financial move. That may change: a WPSC order improving net-metering terms, a future federal residential credit, or continued rate escalation could shift the math. For most Wyoming homeowners right now, waiting costs very little and rushing costs real money.

Frequently Asked Questions
For high-consumption homeowners on Rocky Mountain Power or CLFP, the answer can still be yes. Payback runs 10 to 13 years at current rates, with net savings of $6,000 to $14,000 over 25 years. For lower-consumption homes or co-op customers, the loss of the credit pushes the math into negative territory.
It depends on consumption, utility, and financing. High-consumption RMP customers paying cash see payback in the range of 10 to 13 years. Lower-consumption homes or those with loan interest may run 14 to 18+ years. Co-op customers with avoided-cost crediting face even longer timelines.
Yes. W.S. § 37-16-101 requires investor-owned utilities and cooperatives to offer net metering for systems up to 25 kW. Monthly excess rolls forward at full retail. Any credit remaining at the start of each calendar year is purchased at the utility’s avoided cost, which runs as low as 1 to 4 ¢/kWh.
An 8-kW system costs about $24,000 to $29,000 solar-only, or $38,000 to $45,000 with a 13.5 kWh battery. Wyoming-specific installed cost averages $3.33 per watt. No federal residential credit applies for systems installed after December 31, 2025.
Solar leases are legal and available through national providers. PPAs are legally uncertain: Wyoming has not affirmatively authorized residential third-party power sales, and a PPA provider could face “public utility” classification. Prefer a lease if going the zero-down route.
Directly. RMP’s May 2026 filing for an 8.8% increase, on top of prior rate cases, shortens payback for existing solar owners and improves the math for new buyers. Each 1 ¢/kWh increase in the residential rate adds about $130 per year in offset value for an 8-kW system producing 13,200 kWh annually.
The I-80 corridor from Cheyenne to Rock Springs sees ASCE 7 basic design wind speeds of 115 to 130 mph. Racking and attachment systems must be engineered for these loads, which adds cost and requires an installer with local structural experience. Mountain communities also face snow-load requirements of 50 to 100+ psf.
Wyoming exempts solar equipment from state sales tax. Net metering provides ongoing bill credit. There is no state income-tax credit (Wyoming has no income tax), no confirmed property-tax exemption in primary law, and no active rebate program.
