Orland Park, IL Solar Energy: Panel Permits (2026)

Orland Park requires a building permit for solar PV system installation, including structural review of the roof to confirm it can support the additional load, electrical review for compliance with the National Electrical Code Article 690 (PV systems) and 705 (interconnection), and fire access pathway requirements per the International Fire Code. Roof-mounted residential systems on single-family homes are generally permitted by right in residential zones consistent with the Illinois Solar Rights Act (765 ILCS 165), which limits the ability of municipalities and HOAs to prohibit solar. Ground-mounted systems on residential lots may require special review for setbacks and screening. Permit applications typically include manufacturer specs, structural calculations, electrical single-line diagram, and a site plan. ComEd net energy metering interconnection is processed separately through ComEd's online application portal. Inspections include rough electrical, final electrical, and witness of utility commissioning. Battery storage systems trigger additional electrical and fire code requirements including spacing, ventilation, and signage.
