Everything Wyoming homeowners need to know: costs, incentives, net metering policy, and what makes this state unique for solar.
Quick answer
Wyoming solar economics depend mainly on 5.6 average peak sun hours, an estimated $2.9/W installed cost, 9.0¢/kWh electricity, and the state's current net-metering rules.

Key fact about Wyoming solar
Wyoming has outstanding sun hours (5.6/day, better than Florida) but the cheapest electricity in the US (~$0.09/kWh). The math is challenging — solar makes more sense bundled with EV charging or backup power needs.

Wyoming Net Metering Policy
Full retail net metering (WPSC rules)
Wyoming requires full retail net metering for systems up to 25 kW. Rocky Mountain Power and other utilities must credit exports at retail. Wyoming has some of the best solar resources in the US but the lowest electricity rates.
Wyoming Solar Incentives
Available in addition to any utility rebates. Federal 25D credit is $0 for homeowner-owned systems from 2026.
- ✓No state income tax (no credit opportunity)
- ✓Property tax exemption on solar

State-specific decision guide
What to verify before signing a Wyoming solar quote
In Wyoming, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models full retail net metering (wpsc rules). Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 4–8 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
