Is Plug-In Solar Really Plug-and-Play?

Summary

In a few places, legally, close to it: Utah lets qualifying devices run with no utility approval and no fees. The catch is the word qualifying. Utah and Virginia both require a device of 1,200 W or less that meets the National Electrical Code, carries certification from a nationally recognized testing laboratory, and includes a feature that keeps it from energizing the building's wiring during an outage.

The device has to qualify first

Utah defines a portable solar generation device as a moveable PV device with a maximum output of 1,200 W, designed to connect through a standard 120-volt AC outlet, built to the latest National Electrical Code, and certified by Underwriters Laboratories or an equivalent lab. A separate provision requires a device or feature that prevents it from energizing the building's electrical system in a power outage.

California's SB 868, which cleared the Legislature in August 2026, goes further on paper. It calls for certification "as a plug-in photovoltaic system," and it requires the outage-isolation feature itself to be certified.

Some states want to hear from you

Virginia, starting January 1, 2027, requires customers to notify the utility before installing. SB 868 would let California utilities ask for the address, make, model, and size through a simple online registration form. No approval is not the same as no paperwork.

What utilities are worried about

The California Assembly utilities committee's June 2026 analysis collects the utilities' objections: nothing physically prevents these devices from exporting to the grid; unexpected grid conditions could compound phase imbalances and circuit overloads; and standard U.S. receptacles (NEMA 5-15) are not fully touch-safe. It also cites a late-2025 UL white paper warning that overload current can pose a risk of fire or shock.

Virginia's law has a narrower carve-out as well. Devices that put no more than 391 W into the receptacle are exempt from product listing provisions that would require changes to the building's premises, wiring, or electrical panels.
