Express Permit Program solar path for eligible energy storage paired with PV
Chicago's Express Permit Program solar instructions cover small rooftop solar PV systems with or without associated energy storage. The eligible scope includes installing an energy storage system associated with a solar photovoltaic system up to 20 kWh, with a 10 kWh limit for some battery types, while projects outside the listed limits or occupancy/height restrictions need a different City review path.
