Net metering & export compensation
220 ILCS 5/16-107.5 — retail-rate netting through 2024, then transitioning to a separate distribution rebate plus energy/capacity credit (Smart Inverter Rebate).
Interconnection process
ICC Part 466 distributed generation interconnection standards with Level 1 fast track for ≤10 kW inverter systems.
Permitting & inspection
Local building departments; Chicago has its own electrical code (CEC) that is stricter than NEC.
Utilities operating in this state
ComEd, Ameren Illinois, MidAmerican, plus municipal utilities (Springfield CWLP, Naperville, etc.) and co-ops.
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.

Bottom line for plug-in solar buyers in Illinois
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.
