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.

Pending legislation

Coming Soon — Illinois is considering plug-in solar legislation

Would permit plug-in solar systems up to 391W to connect to standard outlets without utility approval, fees, or UL certification requirements.

Solar you can use in Illinois today, while you wait

Plug-in solar that ties into your home's wiring isn't legal here yet — but a portable solar generator (a panel charging a battery you plug devices into directly) never touches your home's wiring, so it's legal everywhere, including Illinois, right now.

What to Expect If This Passes

🔌

Up to 391W, no permit

The bill as drafted would allow systems up to 391W AC connected to a standard household outlet — no permit, no utility approval required.

No net metering

The bill does not include net metering for plug-in systems. Excess generation would not be credited. Self-consumption maximization is key.

🏠

Renters included

The bill does not restrict installation to homeowners. Renters would still need landlord consent, but no permanent installation is required.

Panels typically last 25–30 years with a 25-year output warranty. Microinverters carry a 10–25 year warranty depending on brand. Battery modules degrade faster — expect 10–15 years before capacity drops below 80%. The 25-year savings figure above assumes the panel and inverter run for the full window; budget ~$200–$400 for an inverter swap around year 15 if needed.

Frequently Asked Questions

Can my HOA stop me from installing solar panels in Illinois?
No. The Homeowners' Energy Policy Statement Act (765 ILCS 165) prohibits HOAs, condo associations, and deed restrictions from banning solar energy systems outright. The association can regulate placement, but restrictions cannot cut a system's production by more than 10%.
Does the Illinois Solar Rights law protect renters from landlord restrictions?
Not directly. The 765 ILCS 165 protections focus on HOA/association rules for property owners, not landlord-tenant relationships. As of mid-2026, landlords can still restrict balcony or plug-in solar devices, since proposed legislation that would have limited such restrictions did not become law.
Is plug-in or balcony solar legal to use in Illinois right now?
There's no law specifically banning small plug-in solar devices, but there's also no specific exemption from standard utility interconnection rules. A 2025-2026 bill (the Plug-In Illinois Act) that would have exempted units up to 1200W from interconnection requirements stalled after opposition, so legal clarity is still pending.
How does net metering work for new solar customers with ComEd or Ameren Illinois?
Since January 1, 2025, new solar customers are on 'Smart Solar Billing,' a supply-only net metering structure that credits excess exported electricity at a lower rate than the old full retail-rate net metering. ComEd customers also receive a one-time Distributed Generation rebate of $300 per kW to help offset the change.
Do I need utility approval to connect a small solar device to my home outlet in Illinois?
Under current rules, any grid-connected generation device generally needs to go through Ameren Illinois or ComEd's Distributed Generation Interconnection process and receive a Certificate of Completion under Illinois Administrative Code Title 83 Part 466. Proposed legislation to waive this for very small plug-in units has not yet passed.
