Very low electricity rates, harsh winters — the Wyoming solar reality.
| ☀️ Peak Sun Hours | 4.6 hrs/day (good — better than most northern states) |
| ⚡ Avg Electricity Rate | $0.108/kWh (EIA 2025 — among the lowest in the U.S.) |
| 🏠 Typical 6 kW System Cost | $17,500 after 30% Federal Tax Credit (ITC) |
| 📈 Payback Period | 15–18 years (industry estimate for average WY home) |
| 🔌 Net Metering Policy | ⚠️ Limited — not state-mandated, varies by utility |
| 💰 25-Year Total Savings | $28,000+ (estimate based on 4% annual electricity inflation) |
Wyoming has the lowest electricity rates in the country and harsh winters — two factors that make solar economics very challenging. Here's an honest assessment:
Wyoming's average electricity rate ($0.108/kWh) is the lowest in the country (EIA 2025). This means each kWh of solar production saves you very little money — and payback periods are the longest of any state (15–18 years with net metering, 22+ years without).
Despite its northern latitude, Wyoming gets about 4.6 peak sun hours per day annually (NREL data) — better than Montana, North Dakota, or South Dakota. A 6 kW system in Cheyenne produces about 7,400 kWh/year.
Wyoming does not have a state law requiring net metering. Some utilities may offer it voluntarily, but terms vary widely. Most Wyoming electricity customers are served by rocky Mountain Power (PacifiCorp) or electric cooperatives — check directly with your utility.
The 30% Federal ITC applies to Wyoming solar installations. For a $25,000 system, that's $7,500 — a substantial reduction in upfront cost.
Wyoming's harsh winters, remote locations, and occasional severe weather make battery storage a particularly smart addition to solar. With battery backup, you maintain power during outages that can last days in remote Wyoming areas.
Wyoming solar customers can claim 30% of total system cost as a federal tax credit, including equipment, installation, permitting, and battery storage.
Since Wyoming has no state net metering law, check directly with your utility:
Wyoming offers a property tax exemption for renewable energy systems, meaning your solar installation will not increase your property tax assessment.
Location: Cheyenne, WY
System size: 6 kW (18 × 350W panels)
Roof direction: South-facing, 41° tilt
Electricity rate: $0.108/kWh (Rocky Mountain Power)
Annual production: ~7,400 kWh (NREL PVWatts estimate for Cheyenne, WY)
| Item | Amount |
|---|---|
| Annual solar production | 7,400 kWh |
| Value at retail rate ($0.108/kWh) | $799 |
| System cost after 30% ITC | $17,500 (upfront, after tax credit) |
| Simple payback period | ~17 years |
Estimated monthly savings: ~$67 | Yearly: $799
Note: Without net metering, payback extends to 24+ years. Adding battery storage ($10,000–$15,000) extends payback further but provides backup power value in remote WY locations.
Wyoming has some of the harshest winters in the U.S. Here's how that affects solar:
| Month | Production (kWh) | % of July Production |
|---|---|---|
| January | 290 | 24% |
| April | 790 | 66% |
| July | 1,200 | 100% |
| December | 250 | 21% |
Key takeaway: Winter production in WY is very low (21–24% of peak). Snow cover can persist for days or weeks. Solar in WY works best with battery storage (to provide backup power during outages and store summer surplus) or in off-grid applications where connecting to the grid is prohibitively expensive.
Wyoming does not have a state law requiring net metering. Some utilities may offer it voluntarily — check with Rocky Mountain Power or your local electric cooperative for current terms.
Solar in WY has the longest payback period of any state (15–18 years with net metering, 24+ years without). It makes the most sense for (1) off-grid properties where grid connection costs $20,000+, (2) homes with battery storage for backup power, or (3) customers who want to hedge against future electricity rate increases.
Battery storage is highly recommended in Wyoming. The state's harsh winters, remote locations, and occasional severe weather make backup power very valuable. In off-grid applications, battery storage is essential.
Wyoming has abundant coal and natural gas resources, and most electricity is generated in-state at low cost. However, as coal plants retire due to environmental regulations, rates are projected to rise — making solar a potential hedge.
Not all solar installers are equal. When choosing a solar installer in Wyoming, consider these factors:
Verify the installer holds the required state and local licenses. In Wyoming, solar installers should have proper electrical contractor licensing. Also look for North American Board of Certified Energy Practitioners (NABCEP) certification — this is the gold standard for solar installation training.
Ask how many solar systems the company has installed in Wyoming. A local installer with 5+ years of experience and 500+ installations is preferable to a new national chain with less local knowledge. Local installers also know local permitting requirements and utility interconnection processes.
Not all solar panels and inverters are equal. Ask which brands the installer uses and why. Tier 1 solar panel manufacturers (like SunPower, LG, Panasonic, Jinko, LONGi) offer better warranties and degradation rates. For inverters, Enphase microinverters and SolarEdge power optimizers are widely regarded as top-tier.
Solar panels typically come with 25-year performance warranties (guaranteeing 80-85% production at year 25). Inverters have shorter warranties (10-12 years for microinverters, 5-10 years for string inverters). Make sure your installer offers workmanship warranties (covering installation errors) of at least 10 years.
Always get at least 3 quotes from different installers. Compare not just price per watt, but total system cost, equipment quality, warranty terms, and customer reviews. The cheapest quote is not always the best value — a slightly more expensive system with better equipment and warranty can save you money over 25 years.
Solar panels require minimal maintenance, but a few simple steps can maximize their lifespan and production:
With proper maintenance, solar panels typically last 30-35 years (exceeding their 25-year warranty). The inverter may need replacement around year 12-15, but this is a normal part of system lifecycle.

The average cost of a residential solar system in Wyoming is $15,000-$25,000 before incentives (for a 6-10 kW system). After the 30% federal Investment Tax Credit (ITC), the net cost drops to roughly $10,500-$17,500. Actual costs vary based on roof complexity, panel brand, installer choice, and local permitting fees. Wyoming homeowners should get at least 3 quotes to compare pricing.
All U.S. homeowners qualify for the 30% federal Investment Tax Credit (ITC) through 2032. This credit reduces your federal taxes by 30% of your total system cost. In addition to the federal ITC, some states offer additional rebates, property tax exemptions, or sales tax exemptions on solar equipment. Check with your local utility and the Database of State Incentives for Renewables & Efficiency (DSIRE) for Wyoming-specific programs.
The typical solar payback period in Wyoming ranges from 7 to 12 years, depending on your electricity rate, system size, available incentives, and financing terms. After the payback period, your solar panels essentially produce free electricity for the remaining 15+ years of their 25-30 year lifespan. Higher electricity rates and strong sun exposure lead to faster payback periods.
Yes. According to a study by Lawrence Berkeley National Laboratory (LBNL), homes with solar systems sell for an average of $15,000-$25,000 more than comparable homes without solar. The exact premium depends on your location, system size, and age. Many states including Wyoming offer property tax exemptions for the added value from solar, so you won't pay higher taxes even though your home is worth more.
Solar works best on south-facing roofs with minimal shading, but east-west orientations can still produce 80-90% of optimal output. Key factors include: roof condition (should have 15+ years of life left), tilt angle (30-45 degrees ideal), and shading from trees or nearby buildings.
