Solar installation across Illinois.
ETW Energy installs solar and battery storage for homes across Illinois, from the Chicago metro to central Illinois. Illinois supports residential solar through state incentive programs, and outage resilience is a common reason homeowners add storage — especially now that exported energy is credited at a lower value than it used to be.
Yes, Illinois has real winters — but modern solar still produces meaningfully here across a full year, and the design accounts for the local climate rather than pretending it away.
The Illinois solar landscape
Which utility serves you shapes the design — the Chicago metro is largely served by ComEd, while central and southern Illinois are served by Ameren Illinois. An important 2025 change: for systems connected after the end of 2024, Illinois moved from full retail net metering to supply-only net billing, so exported energy now credits the supply portion of your bill rather than the full retail rate. To help offset that, the state added a smart inverter rebate, and the Illinois Shines program continues to support solar and storage.
Because these programs and their details change over time, we confirm exactly what currently applies to your project before you count on it. And because exports are worth less than they were, using more of your own power — often with a battery — matters more than it used to.

Solar in Illinois — common questions
Are there incentives for solar or batteries in Illinois?
Yes — the Illinois Shines program supports solar and storage, and new systems can qualify for a smart inverter rebate. One important change: as of 2025, Illinois moved new solar customers from full retail net metering to supply-only net billing, so export credits are worth less than they used to be. We confirm exactly what currently applies before you commit.
Does solar work in Illinois’ climate?
Yes. Production is lower in winter and higher in summer, but over a full year a properly sized system produces meaningfully. We design for the local sun, not a sunbelt assumption.
