Quick Answer: Illinois Solar Permits & Incentives Overview

Installing solar in Illinois requires local permits and a strategy to stack available incentives. These incentives can significantly reduce your net system cost.

Every residential and commercial solar PV installation requires local building and electrical permits. A zoning review may also apply. Illinois does not have a single statewide residential solar permit; cities or counties issue permits, inspect work, and approve interconnection.
