Wyoming Solar Guide: Costs, Incentives & Net Metering (2026)

Cost of solar in Wyoming

Currently, there is insufficient public data from sources like the Lawrence Berkeley National Laboratory (LBNL) to provide a reliable, statistically significant median installed cost for residential solar in Wyoming. Because the residential solar market in Wyoming is relatively small compared to other states, system costs can vary widely depending on your location, your chosen installer, and the specifics of your roof.

Wyoming residents consume an average of 8,317 kWh of electricity per year. Despite the lack of specific pricing data, Wyoming's strong average of 4.57 peak sun hours per day means that panels installed here will generate a robust amount of electricity (about 1,601 kWh per kW of solar capacity annually).

Net metering and export rules

Wyoming has a statewide net metering law (Wyo. Stat. § 37-16-101) that mandates investor-owned utilities, electric cooperatives, and irrigation districts to offer net metering for renewable energy systems, including solar, up to 25 kW in size. This ensures that you can connect your solar panels to the grid and get credit for the excess electricity you send back.

However, the way utilities value your excess electricity can differ. The Wyoming Public Service Commission (PSC) gives utilities some flexibility:

• Retail Rate vs. Avoided Cost: Some utilities credit your monthly excess generation at the full 1:1 retail rate, meaning a kilowatt-hour (kWh) sent to the grid offsets a kWh you consume from the grid equally. Other utilities use an "avoided-cost" rate, which is typically much lower than what you pay for electricity.
• Annual True-Up: At the start of each calendar year, any unused credits remaining in your account are purchased by the utility at their avoided-cost rate.
• No Extra Fees: Utilities are legally prohibited from charging net-metered customers any additional fees beyond standard minimum monthly charges.

Export rates vary by utility. Monthly excess generation may be credited at the full retail rate (a 1:1 kWh credit) or converted to a monetary credit using the utility's avoided-cost rate. All unused credits remaining at the end of the calendar year are purchased by the utility at the avoided-cost rate.
