State solar guide
Wyoming solar economics in 2026 depend entirely on your utility rate, available state incentives, and net-metering rules. The federal residential credit expired December 31, 2025. We present the honest picture for your location.

Net metering
The Wyoming Public Service Commission mandates net energy metering statewide for systems up to 25 kW. All homeowners connected to investor-owned utilities have access to the program. Excess solar earns full retail-rate credits (minus minor fees) for exported generation. Credits roll forward monthly. At year-end, utilities purchase unused credits at an avoided-cost rate.
Rocky Mountain Power (PacifiCorp) is the primary investor-owned utility serving most of Wyoming. Montana-Dakota Utilities serves northeastern Wyoming. Black Hills Power and Light serves the Black Hills region. All three offer full retail net metering under Wyoming PSC rules. Year-end unused credits are purchased at avoided cost by the utility. Wyoming's high sun resource means systems are often sized to maximize self-consumption and minimize year-end avoided-cost settlement. Source: EnergySage Wyoming 2026, Wyoming PSC.

State incentive stack
The federal residential credit expired December 31, 2025. The programs below are what remains for Wyoming homeowners. Amounts and availability change; every program is date-stamped and linked to its DSIRE source.
Federal residential solar credit (Section 25D): expired. The Section 25D residential investment tax credit expired December 31, 2025. The residential credit rate is 0%. State and local incentives below may still significantly reduce your net system cost. Commercial systems still qualify for Section 48E (30%).
| Program | Benefit | Eligibility | Status | Source |
|---|---|---|---|---|
| Wyoming Solar Incentives State and local programs Incentive amounts and availability change frequently. Verify at dsireusa.org before relying on any program. | See description Wyoming does not offer a statewide solar rebate program. No major utility rebate programs identified for residential solar as of June 2026. The property tax exemption and full retail net metering are the primary policy supports. Wyoming's strong sun resource (5.36 average peak sun hours) is a natural advantage. | Wyoming homeowners. Verify current programs at dsireusa.org. | Limited | DSIRE (opens in new tab) |
| Wyoming Solar Property Tax Exemption Property tax exemption Confirm exemption filing requirements with your county assessor. | Exemption on solar-added home value (amount varies by local tax rate and system size) Wyoming exempts solar energy systems from property tax assessment under state statute. Home value added by solar installation is not subject to property tax. Exemption applies statewide to systems used for generating electricity. | Wyoming residential property owners with qualifying solar installations. | Active | DSIRE (opens in new tab) |

Savings example
This example uses real Wyoming market data. No federal residential credit is applied. Figures are illustrative; your in-home assessment uses your actual utility bills and the current rate schedule for your specific utility.
Annual production estimated at approximately 12,200 kWh for an 8 kW system at 5.36 peak sun hours. Full retail net metering: assumes 70 percent self-consumption at 13.04 cents per kWh; remaining 30 percent exported at 13.04 cents per kWh full retail (with year-end settlement at avoided cost for any unused carry-forward). Wyoming's below-average electricity rate (13.04 cents) limits the per-kWh savings value, extending payback despite the strong sun resource. Sales tax on hardware not exempt (additional cost). Utility rate escalation at 3 percent annually. Federal residential credit: $0 (expired). Figures are illustrative; your in-home assessment will use your actual bills.

Permitting
Wyoming does not have a statewide solar permit fee cap. Permit requirements vary by municipality and county. Cheyenne, Casper, Laramie, and Gillette each have separate building departments. Given lower solar installation volume in Wyoming, some local AHJs have limited solar permitting experience. Typical residential solar permit approval takes 2 to 6 weeks. SolarAPP+ adoption in Wyoming is limited. Contract to energization typically runs 10 to 16 weeks statewide.
Rocky Mountain Power (PacifiCorp) interconnection review is separate from the building permit and must be completed before energization. Verify current interconnection queue times with Rocky Mountain Power before signing a contract.
Commercial solar in Wyoming
The commercial solar credit (Section 48E, 30 percent) remains available for qualifying commercial projects. Construction must begin by July 4, 2026 to qualify for the full placed-in-service window. Combined with MACRS accelerated depreciation and 100 percent first-year bonus depreciation, the combined first-year federal benefit can reach 45 to 55 percent of project cost for many Wyoming business owners. Direct Pay is also available for nonprofits, municipalities, and other tax-exempt entities.
Commercial solar overviewCommercial solar projects must begin construction by July 4, 2026 to qualify for the 30 percent Section 48E federal tax credit. After that date, the system must be placed in service by December 31, 2027.
