Balcony Solar in Utah
Everything you need to know about plug-in and balcony solar law in Utah, plus what it means for what you're allowed to plug in, and what it saves.
Is it legal?
Yes.
Utah's House Bill 340 took effect on 7 May 2025, making Utah the first U.S. state to legalize plug-in solar. It permits systems up to 1,200W of plug-in solar per customer, which can be plugged into a standard outlet with no permit and no utility approval required.
The law explicitly bars utilities from charging any fee or requiring interconnection review for a qualifying plug-in solar device.
Bright Saver's 180W and 360W kits both sit well below Utah's 1,200W cap, so they need no electrician, no dedicated circuit and no permit.
What You Can Save in Utah
Utah's average residential electricity price is about 11.6 cents per kWh (EIA, 2026 average), among the lowest in the country. A 180 W kit generating about 270 kWh a year saves roughly $31 a year; a 360 W kit roughly $63.
Those are modest numbers on their own. Utah's abundant sunshine keeps the panel producing more hours per day than in most states, and the kit pays for itself over its life with no roof work or contractor needed.
