Commercial Solar Installation in Illinois
Illinois is one of the most commercially active solar markets in the Midwest. Commercial solar can still claim the federal Clean Electricity Investment Credit (Section 48E) in 2026, though it is phasing down with begin-construction and placed-in-service deadlines so timing matters. Accelerated depreciation improves the after-tax payback, and both ComEd and Ameren Illinois offer net metering under ICC rules. Illinois Shines (the Adjustable Block Program) also has a commercial and community solar track that can reduce your effective project cost. We match your building with an installer who actually does commercial solar in Illinois, we do not install ourselves.

Section 48E commercial credit applies in 2026
Commercial solar can still claim the federal Clean Electricity Investment Credit (Section 48E) in 2026, though it is phasing down with begin-construction and placed-in-service deadlines. Businesses can layer accelerated depreciation on the system value to improve the after-tax return further. Your installer and accountant confirm the current rate, deadlines, and how both apply to your project.
Illinois Shines
State REC payments reduce commercial cost
Illinois Shines (the Adjustable Block Program) includes a commercial and community solar track where REC incentive payments can be passed on through reduced project pricing. Your installer confirms current block availability and how much of the incentive applies to a commercial system of your size.
Rate hedge
Lock in a major operating cost for 25 years
Commercial power rates from ComEd and Ameren Illinois trend up over time. A solar roof fixes a portion of that cost for the life of the system, turning an unpredictable line item into a known, declining one as the system pays down.

"We installed our system over a year ago and everything went pretty smoothly. When I had trouble with the system I had someone responding within an hour or so of my support ticket being opened. Great system so far and we love being as green as we can by having solar."
