Installers, contractors and solar service companies whose service area covers Wyoming.
Wyoming is America's coal king and least populous state — and quietly one of its sunniest, averaging more than 5 kilowatt-hours of sunlight per square meter a day across high, clear-skied country. Solar arrived late: the Sweetwater Solar farm, the state's first utility-scale project, came online in 2018, and rooftop systems are still a small but growing sight on ranches and homes where the nearest power line can be a mile — and a five-figure line-extension bill — away.
The one firm rule is net metering, in state law since 2001 for investor-owned utilities, cooperatives, and irrigation districts, covering systems up to 25 kW. With Rocky Mountain Power, which serves about 4 in 10 Wyoming homes, extra power becomes a kilowatt-hour credit on your next bill, one for one, and credits roll month to month. The catch comes each January: any credits left unused are sold to the utility at its avoided-cost rate — about 1.4 cents per kilowatt-hour for fixed solar in 2026, against roughly 14 cents at retail — so a Wyoming system should be sized to your annual usage, never above it. Bills to rewrite the law failed in 2025, so these rules stand; but some co-ops credit monthly excess at avoided cost instead, and city-run utilities (Gillette, Cody, Powell, and others) aren't covered by the state law at all, so get your utility's terms in writing.
There are no state rebates or tax breaks to chase — Wyoming's case is self-reliance: power for stock tanks, shops, and homes that doesn't depend on a long feeder line staying up in a blizzard.
