Solar in Wyoming: Frequently Asked Questions

Is solar worth it in Wyoming?
For many homeowners, yes — though payback is longer than average in Wyoming. Low electricity rates (12.85¢/kWh) extend payback to 9.7 years. But the 25-year savings (~$28,714) still significantly exceed system costs, and electricity prices will likely rise. Wyoming has no state income tax and among the lowest electricity rates in the US (~11¢/kWh), making payback 11–13 years despite good sun.
What solar incentives are available in Wyoming?
Wyoming homeowners can stack multiple incentives: the state solar incentives (federal ITC expired Dec 2025) (ITC) — $6,480 on a typical 8 kW system; a property tax exemption (solar-added home value not taxed); sales tax exemption on solar equipment; and net metering through Rocky Mountain Power / Black Hills. Wyoming has no state income tax and among the lowest electricity rates in the US (~11¢/kWh), making payback 11–13 years despite good sun.
How much electricity do solar panels produce in Wyoming?
Wyoming averages 1517.5 kWh per kWp of solar per year — 1% above the US average. An 8 kW system produces roughly 12,140 kWh/year, with a monthly average of 126.5 kWh/kWp. Output varies by location: southern Wyoming produces more than the north.
How much do solar panels cost in Wyoming?
The average 8 kW system in Wyoming costs approximately $21,600.0 before incentives. After the 30% federal ITC ($6,480), your net cost is around $15,120. Prices range from $2.40–$3.20/watt installed depending on installer, panel brand, and high plains — excellent sun, wind-resistant mounting required.

Going Solar in Wyoming: Step by Step

From first quote to first kilowatt — here is the typical timeline for a residential solar installation in Wyoming. Most homeowners complete this process in 6–12 weeks.

  1. 1
    Get 3 quotes

    Prices in Wyoming average $22,400 for an 8 kW system before incentives. Getting three quotes typically saves 10–15%. Use the same system size so you can compare apples to apples.

  2. 2
    Review your electricity bill

    Your last 12 months of usage determines the right system size. At 12.85¢/kWh in Wyoming, a system that offsets 90% of your bill hits the best cost-per-kWh sweet spot.

  3. 3
    Check state incentives

    Wyoming does not have a statewide solar tax credit, but utility rebates and net metering may still apply. Sales tax exemption on solar.

  4. 4
    Sign contract & apply for permits

    Your installer pulls the building permit and files interconnection paperwork with your utility. Permit approval in Wyoming typically takes 1–4 weeks depending on your county.

  5. 5
    Installation day

    A standard 8 kW residential installation takes 1–2 days. Racking goes on first, then panels, then the inverter is wired to your main panel. The crew usually keeps the power on throughout.

  6. 6
    Utility inspection & interconnection

    After installation your utility inspects the system and approves grid connection. This final step can take 1–3 weeks. Once approved, your meter tracks both import and export.
