New to plug-in solar?

Plug-in solar lets anyone generate free electricity — no roof, no permit, no contractor. A single panel on your balcony can meaningfully cut your bill, especially as rates keep rising.

Wyoming

Not yet legal

Wyoming's plug-in solar push effectively stalled in early 2026: House Bill 146, the 'Affordable Electricity Act of 2026' sponsored by Rep. Liz Storer (D-Jackson), would have exempted small plug-in solar devices from state inspection and utility interconnection approval requirements, but it died in the House Transportation, Highways and Military Affairs Committee around February 17-21, 2026 for lack of a motion to advance, after Rocky Mountain Power, Black Hills Energy, and the Wyoming Rural Electric Association testified against it citing fire and wiring-overload risks. Wyoming has excellent sun hours (~5.5/day) and moderate rates (~$0.115/kWh), giving plug-in solar strong economics if a future bill succeeds.

What You Can Use in Wyoming While You Wait

Plug-in solar that ties into your home's wiring isn't legal here yet — but a portable solar generator (a panel charging a battery you plug devices into directly) never touches your home's wiring, so it's legal in Wyoming right now, no law required.

What a Wyoming Law Could Look Like

⚡

Based on neighboring states

Utah (1,200W), Maine (600W), and Virginia (1,000W pending) provide the template. A Wyoming law would likely allow 600–1,200W systems to plug into standard household outlets — no permit required.

💸

High rates = strong economics

At Wyoming's avg. $0.115/kWh, a 600W system generating ~880 kWh/year saves roughly $101/year. Payback in as few as 8 years at current rates.

Renters and condo owners

Plug-in solar requires no permanent installation — just an outlet. This makes it uniquely accessible to renters and condo owners who can't get rooftop solar.

FAQ

Is plug-in (balcony) solar legal in Wyoming?
There's no Wyoming law specifically authorizing plug-in solar devices, and a 2026 attempt to change that failed. House Bill 146, sponsored by Rep. Liz Storer, would have exempted small plug-in solar systems from state inspection and utility approval requirements, but it died in committee in February 2026 after utility opposition. Plug-in devices remain in a legal gray area.
Why did Wyoming's plug-in solar bill (HB 146) fail?
HB 146 died in the House Transportation, Highways and Military Affairs Committee around February 17-21, 2026, for lack of a motion to advance it. Rocky Mountain Power, Black Hills Energy, and the Wyoming Rural Electric Association testified against the bill, arguing that exempting plug-in solar from inspection and interconnection approval could overload home wiring and create fire hazards.
Can my HOA block solar panels in Wyoming?
Yes, likely. The Wyoming Solar Rights Act establishes solar access as a property right against local government interference but does not restrict HOA covenants. Wyoming has no comprehensive HOA solar-access law, so HOAs generally retain broad authority to prohibit or restrict solar installations, including balcony or patio plug-in devices, through their governing documents.
Does Rocky Mountain Power offer net metering for small solar systems?
Yes, Rocky Mountain Power offers net metering for systems up to 25kW with no overall statewide cap, under its Net Metering Service Schedule No. 135. However, the utility has taken a notably cautious stance specifically toward plug-in solar, testifying against HB 146 in 2026 over safety concerns - distinct from its general support for conventional, professionally-installed net-metered systems.
What's Wyoming's solar potential for a plug-in panel?
Wyoming has excellent solar potential, averaging around 5.5 peak sun hours per day, among the better solar resources in the country, especially in the southern part of the state. Combined with moderate electricity rates (~$0.115/kWh), this gives plug-in solar strong technical performance, even though current state policy and utility opposition limit its legal clarity.
