Plug-in solar in Utah
Utah's plug-in solar law has been in effect since May 2025, longer than any of the other enacted state laws here. It sets a single 1,200 W limit and bars the utility from requiring approval or a fee.
What is Utah's power limit?
The statute allows a portable solar generation device with a maximum output of 1,200 W, connected through a standard 120-volt AC outlet.
Does the utility have to approve it first?
No. The statute bars the electrical corporation from requiring the customer to obtain approval before installing or using the system, and from charging a fee. The device is exempt from interconnection requirements and agreements.
Is notification required?
The statute does not state a notification step. It does not require the customer to notify the utility before or after installation.
What certification does Utah require?
The device must be certified by Underwriters Laboratories or an equivalent nationally recognized testing laboratory, and meet the most recent National Electrical Code. It must also include a feature that prevents it from energizing the building during a power outage.
How Utah differs
Utah took effect in May 2025, earlier than the other states here. It uses a single 1,200 W limit, with no utility approval and no notification step written into the statute.
