Plug-in systems aren't net-metered: surplus sent to the grid earns nothing. ~80% is typical without a battery; 95%+ with one.

What to do now

  1. 1Don't connect a grid-tied plug-in system yet — without a law, it may breach your utility agreement.
  2. 2Consider an off-grid setup in the meantime: a panel charging a portable power station is legal everywhere.
  3. 3Cut your bill today with no-cost measures — see our guide to lowering your electric bill.
  4. 4Contact your Wyoming state legislators: constituent support is what moved the 2026 bills.

Wyoming plug-in solar FAQ

Is plug-in solar legal in Wyoming?

Not yet. A plug-in solar bill was killed or stripped this session. Without a law, connecting a grid-tied plug-in system may violate your utility's interconnection rules. Off-grid setups (a panel charging a portable power station) are allowed everywhere.

How much can balcony solar save in Wyoming?

At Wyoming's average residential rate of 14.36¢/kWh (EIA, July 2026) and about 5.2 peak sun hours a day, a south-facing, tilted 800 W kit saves roughly $150 a year, paying back a $900 kit in about 6.0 years. Vertical railing mounts produce about 30% less.

What is the maximum plug-in solar size in Wyoming?

There is no Wyoming-specific cap yet. Most state laws settle on 1,200 W, the practical limit for a standard 15-amp, 120 V circuit.
