✓ LegalPlug-In Solar Legal Guide
First US state to legalize plug-in solar. Systems must be UL-listed and plug into a standard 120V or 240V outlet. No permit, no utility notification required under 1,200W.
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.

HOA & Landlord Rules
The #1 real-world blocker for renters & condo ownersUtah has no state law prohibiting HOAs from restricting plug-in solar. HOAs may ban or restrict balcony/plug-in systems through their CC&Rs. However, because plug-in systems require no permanent installation or structural modification, many HOAs have not specifically addressed them — review your CC&Rs carefully.
HB 340 does not override landlord authority. Landlords may restrict modifications to the property. Because plug-in solar requires only an outlet (no wiring changes), it is more likely to be permitted than rooftop systems. Get written permission before installing.
Utility: Rocky Mountain Power
Rocky Mountain Power does NOT allow net metering for plug-in solar systems. Excess generation that flows to the grid is not credited — any unself-consumed power is simply donated to the grid. Under HB 340, systems under 1,200W do not require an interconnection agreement with RMP. Rocky Mountain Power has not formally opposed plug-in solar legislation.
