What the law says now
HB 146 remains a failed proposal, not an enacted law. The Wyoming legislature lists its last action as “Died in Committee” on March 3, 2026. Bright Saver describes it as deferred to the 2027 session; that differs from the official action wording, and an expected return is not passage.
The proposal would define qualifying devices with “a maximum power output of not more than” 1,200 W per meter. The bill does not say whether this is AC or DC output. It also specifies connection through a standard 120 volt AC outlet and certification of the system by Underwriters Laboratories or an equivalent nationally recognized testing laboratory.
If passed, the proposal would exempt qualifying devices from interconnection agreements and prohibit utilities from requiring approval before installation or use. It would also require a feature preventing energization of the building or backfeeding into the utility system during an outage. These are proposed protections, not permissions you can rely on now.
Your options before buying
A solar-charged portable power station offers an option without a grid connection when used separately from your home's electrical system. EcoFlow says its DELTA Pro 3 supports solar charging. Homeowners can also seek rooftop solar quotes rather than wait for a plug-in solar bill.
Before buying a grid-connected kit, ask your utility what requirements apply, and check permission with your landlord or HOA where relevant. HB 146's proposed utility exemptions do not resolve those questions today. Check certification for the complete system, rather than assuming a component certification covers the kit.
For planning if a law passes, the calculator gives 877 kWh in a typical year for an 800 W panel array with an 800 W inverter limit, mounted vertically facing south near Wyoming's population center. With a 164 W home base load, 444 kWh is used at home, worth $62 a year at 13.95 cents/kWh, with no payment assumed for exports. Use the calculator to compare your location and mounting.
