Not yet. Illinois has no plug-in solar law.
Without a specific law, connecting any solar device to your home's wiring falls under your utility's interconnection rules. A bill (SB 3104) is still pending.
The spring 2026 session ended without a floor vote on plug-in solar. The bill technically remains on the books until the General Assembly ends in January 2027.
Plug-in solar devices
Approved 9–4 by the Senate Energy and Public Utilities Committee on March 12, 2026, then stalled. Amendments would have delayed larger systems until the National Electrical Code is updated, and sponsors stopped pushing it after opposition from the electrical workers union. Floor amendments were sent back to committee on July 2, 2026.

With no plug-in solar statute, a grid-tied kit is treated like any other generator connected to your home. Utilities generally require an interconnection application before you connect anything that can push power into the wiring, and connecting without approval may violate your utility's terms of service. Plugging in a kit is not clearly legal or clearly illegal; it is unapproved.
Federal bill. Socket Full of Sunshine Act (H.R. 10851): Introduced in Congress on October 19, 2026 by Rep. Rob Menendez (D-N.J.). It would remove utility approval and fees for plug-in systems up to 1.2 kW nationwide, give state regulators two years to set a standard, bar landlords from blocking tenants with some exceptions, and fund state rebates of up to $1,000 for low- and middle-income households. It has not passed. Source.
Illinois's average residential price was 19.2¢ per kWh for January–August 2026, above the US average of 18.2¢ and up 10% from the same months of 2025 (EIA). That ranks 16 of 51 for price, so these are the savings you would see if the kit were allowed.
| 800 W kit, $700 | kWh per year | Savings per year | Payback |
|---|---|---|---|
| Hanging on a south-facing railing | 763 | $119 | 5.9 years |
| Hanging on an east- or west-facing railing | 581 | $102 | 6.9 years |
| Tilted 35° on a stand, facing south | 1111 | $154 | 4.5 years |

Yes. Panels that charge a portable power station, with your devices plugged into the station rather than a wall outlet, are not connected to the grid and do not need utility approval. Grid-tied plug-in kits are a different matter until Illinois passes a law or your utility approves the connection.
At Illinois's average residential price of 19.2¢/kWh, an 800 W kit hanging on a south-facing railing would save about $119 a year in our model, paying back a $700 kit in about 5.9 years. East- or west-facing railings save about $102.
