Tax credit
#01
Federal solar tax credit (Section 25D, ended for 2026 purchases)
The 30 percent federal residential tax credit (Section 25D) applied through December 31, 2025 and is not available for a purchased home system placed in service after that date, so most 2026 homeowner purchases cannot claim it. If you go solar through a lease or a power purchase agreement, the provider may still claim the business version of the credit (Section 48E) and pass part of the value through in your rate. Confirm your eligibility with your installer and a tax advisor.

Illinois Shines (Adjustable Block Program)
Illinois Shines is the state-administered solar incentive program run by the Illinois Power Agency. Under the Distributed Generation track, Approved Vendors receive Renewable Energy Credit (REC) payments from utilities and may pass those savings on to homeowners through reduced equipment or installation costs. Two changes took effect with the 2026-27 Program Year, which opened on June 1, 2026, and both matter to what you are quoted. First, under the Clean and Reliable Grid Affordability Act the Small DG payment structure changed from 100 percent payment at energization to 50 percent at energization with the remainder paid ratably over the subsequent six years, for applications ICC-approved on or after June 1, 2026. That halves the cash an Approved Vendor has in hand at the point they price your job, so expect the upfront discount to be smaller than older guidance suggests and ask how the vendor is handling the deferred half. Second, a $20 per REC adder is available for customer-owned Small DG projects during the 2026-27 Program Year, which the program states is to alleviate the known challenge of the lost availability of the federal Investment Tax Credit, so it partly offsets the end of Section 25D. When shopping installers, ask each vendor for their Disclosure Form showing exactly how much of the Illinois Shines REC payment they are passing on to you, and whether the adder is included. Participation requires using an Approved Vendor; the Block Capacity Dashboard is the authority on current availability.

Illinois Solar for All
Illinois Solar for All is a separate state program for income-eligible residents. Qualifying households receive solar through terms that guarantee their electricity costs are lower than they would have been without solar, either through on-site panels or community solar subscriptions. The program serves homeowners, renters (via community solar), and multifamily building owners. Eligibility is income-based; check the program website to see if your household qualifies before getting a quote.

Net metering · Illinois
Net metering (ICC-regulated, ComEd and Ameren Illinois)
Illinois requires investor-owned utilities to offer net metering under Illinois Commerce Commission (ICC) rules. Excess power your panels send to the grid is credited against what you draw at other times. ComEd and Ameren Illinois are the two major providers serving most of the state. Illinois net metering rules have been subject to ongoing ICC proceedings as part of broader distributed generation policy updates, so credit rates and program terms can change. Your installer confirms the current net-metering tariff and any applicable charges for your utility before your project is quoted.
Worth checking before you sign:
taking a rebate can change your net-metering terms, and export credit rules
differ by utility. Your matched installer confirms the exact numbers for
your address.
