Solar Panel Cost in Wyoming (2026)

Net metering: Net metering required of all utility types to 25 kW

Wyoming requires net metering of every kind of electricity provider. Investor-owned utilities such as Rocky Mountain Power, rural electric cooperatives and municipal providers must all offer it for residential solar systems up to 25 kW. That is worth stating because it is genuinely unusual. Across the states covered on this site, the recurring caution is that a statutory requirement reaches only the investor-owned utilities while cooperatives and municipals set their own terms, which is why so many pages tell readers to check who bills them before trusting a figure. Wyoming largely removes that problem: whoever serves your address, the obligation applies. The individual system capacity limit of 25 kW is comfortably above what a household would install, so it rarely constrains a design. What deserves more attention is the fixed side of the bill. The Rocky Mountain Power January 2026 tariff carries a basic charge of $24.24 per month alongside a flat energy rate of 12.175 cents per kWh under Schedule 2. Roughly $291 a year of that bill is not about kilowatt hours at all and does not fall as your consumption does. A solar system reduces the energy portion of your bill; it does not touch the basic charge. So a projection that models savings as a percentage of your current bill will overstate the result, sometimes substantially, and the correct approach is to model avoided kilowatt hours at the energy rate and leave fixed charges untouched.
