City of Philadelphia - Streamlined Solar Permitting and Fee Reduction
Quick Summary
Residential solar systems of 10 kW or less on 1- or 2-family homes qualify for streamlined permitting through Philadelphia's combined "EZ Permit" process and reduced fees, simplifying what would normally require separate electrical and building permits. Your roof must have a slope of 17% or less, cannot be on engineered trusses without a structural engineer's letter, and the property cannot be historically designated; Philadelphia's Solar Panel Installation Overview guides you through the full permitting and installation process.
