Utility rules and programs for Champaign

Ameren Illinois and Eastern Illini Electric Cooperative serve Champaign County, so which rules apply depends on your address.

UtilityTypeSolar export rule
Ameren Illinois Companyinvestor-ownedAmeren Illinois credits exports for 2025-and-later systems against supply and transmission charges only; systems completed by Dec. 31, 2024 keep full netting, which ends for delivery charges if you take the generation rebate. We could not open Ameren’s own pages, so these terms come from summaries; confirm with Ameren.
Eastern Illinois Elec Coopmember-owned cooperativeEastern Illini Electric Cooperative’s net metering program has been full since July 2020; new systems use net billing, which values your own use at retail and pays an excess-power rate for the rest (systems up to 100 kW and 110 percent of past use).

Program details are from each utility’s own pages (read October 2026). See the Illinois incentives table for statewide credits and a status for every program.

Solar Panel Installation in Champaign FAQs

Is solar worth it in Champaign?

The sun is strong (about 1,170 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Illinois incentives for the state credit.

Is there a federal solar tax credit in 2026?

No. The federal 25D credit ended for expenditures after December 31, 2025. Illinois has no state solar income tax credit that we found; its state help is the Illinois Shines payment, utility rebates and a property tax valuation rule (35 ILCS 200/10-10).

Do I need a permit for solar panels in Champaign?

Usually yes, and the utility may need to approve solar and batteries. Champaign Fire Department, Building Safety Division handles permits in Champaign; see the permit information above.
