Plug-In Solar in Idaho

Idaho has no statewide net-metering law. Each utility runs its own program approved by the IPUC; Idaho Power moved residential solar onto a non-NEM net billing structure in 2024.

Policies change frequently — verify every detail with your utility, state public utility commission, energy office, local building department, and a licensed electrician before purchasing or installing any plug-in solar equipment.

Net metering & export compensation

Electrical code (NEC) considerations

The U.S. National Electrical Code (NEC) does not have a listed pathway for backfeeding a standard 120 V receptacle from a solar inverter. Article 705 covers interconnected power production sources and generally expects a dedicated, breakered, labeled circuit. Many AHJs that follow NEC 2017/2020/2023 will not approve a cord-and-plug PV connection on that basis, regardless of state policy.

HOA, landlord & solar access

Check your lease, HOA covenants, and condo rules. Many states have a 'solar access' or 'solar rights' law that limits HOA restrictions on rooftop PV, but those statutes were written for permanent installations and rarely mention plug-in or balcony kits explicitly. Renters almost always need written landlord permission.

Official sources to consult

Bottom line for plug-in solar buyers in Idaho

Even where state policy is favorable, U.S. utilities and inspectors generally do not recognize a cord-and-plug PV connection. If you want to be fully code-compliant and earn export credits, plan on a permitted, hard-wired install by a licensed electrician with a signed interconnection agreement. Off-grid uses (running a single appliance, charging a battery, RV/shed power) avoid most of these rules but still need to follow product instructions and basic electrical safety.
