Is Solar Worth It in Illinois?
Illinois is a solid solar market, driven by the Illinois Shines Adjustable Block Program (ABP). The program provides upfront SREC value that significantly lowers net system cost, on top of the 17.3-year payback in our base planning model.
Nationally, EnergySage reports the average homeowner saves about $61,000 over 25 years by going solar — though actual savings vary by state, electricity rate, and system size.
Key Advantage
Illinois Shines ABP provides upfront lump-sum payment for 15 years of SREC value at signing — eliminating the uncertainty of waiting for annual SREC payments.
Watch Out For
Illinois Shines has experienced program pauses and waitlists. Current status should be verified before sizing your system around incentive availability.
