Portable solar generation (plug-in solar)

Customers in Utah can use plug-in photovoltaic (PIPV) – also known as balcony or portable solar – as a result of Utah H.B. 340 that was signed it into law in 2025. Unlike traditional solar generation systems that are permanently installed (e.g., rooftop or fixed installations), portable solar generation systems are designed to plug directly into a standard electrical outlet in a home. We're providing guidance for renters and homeowners on how this law applies and what you need to know. 

This is allowed for Utah residential customers per H.B. 340. At this time, it is not available for customers in our other service areas in Wyoming and Idaho.

Solar product criteria

• The PIPV device should have a maximum power output of no more than 1,200 watts.
• It should be designed to connect to a building’s electrical system via a standard 120-volt alternating current (AC) outlet.
• It is intended to offset a portion of the customer’s electricity consumption.
• It should comply with the most recent version of the National Electrical Code (NEC).
• It should be certified by Underwriters Laboratories (UL) or an equivalent nationally recognized testing laboratory.
• It should include a device or feature that prevents backfeed to the utility during a power outage.

How it works

• Customers are exempt from utility net metering interconnection and program requirements.
• Utilities may not require customers to obtain approval prior to installation or use.
• Utilities may not charge fees, require additional controls, or require installation of extra equipment.
• Utilities are not liable for damages or injuries caused by portable solar generation systems.
