Illinois Solar FAQ

+How much does residential solar cost in Illinois?

A typical 8–10 kW system runs $20,000–$35,000 before incentives. The federal ITC currently covers 30%, and Illinois may offer additional state rebates.

+Do I need a battery with solar in Illinois?

Optional — but a battery (Tesla Powerwall, Enphase) provides backup during Illinois outages and improves time-of-use savings under the local utility's rate plan.

+How long does solar permitting take in Illinois?

On-site work runs 1–3 days. Permitting and PTO (permission to operate) in Illinois can add 4–10 weeks depending on the utility.
