Solar Rebates in Chicago, Illinois (2026)

Chicago — in ComEd territory — is one of the strongest Illinois solar markets thanks to the Illinois Shines (Adjustable Block Program) SREC market. Customers receive Solar Renewable Energy Credits over 15 years, typically worth $9,000–$14,000 cumulative on an 8 kW system. Most Chicago installers offer upfront SREC monetization in exchange for the assignment — homeowners receive a lump-sum payment at install. Combined with federal 25D (30%), Illinois property tax exemption (added value not assessed), Illinois sales tax exemption, and ComEd 1:1 net metering, Chicago solar delivers ~50–60% effective cost coverage. ComEd Hourly Pricing rate plan offers additional savings for time-shift households.

Chicago-specific FAQ

Illinois Shines lump-sum vs annual? +

Most Chicago installers offer lump-sum upfront monetization. Annual sale gives upside if SREC market rises but adds complexity.

Chicago snow load and roof orientation? +

Heavy winter snow reduces production December–February. Annual production ~1,000 kWh per kW installed. Optimal orientation south or southwest.

ComEd Hourly Pricing — worth switching? +

For households with EV or large midday loads, yes. Off-peak rates significantly lower than tier 2.

Federal pathway
