Philadelphia Solar Permit Guide

Philadelphia solar work can require electrical permits, building permits, PECO interconnection, contractor licensing, and inspection certification.

Permit takeaway

Philadelphia says solar installation, replacement, repair, renewal, or alteration requires the appropriate permits, including an Electrical Permit and sometimes a Building Permit.

Zoning and placement

EZ permit eligibility is limited by system size, dwelling type, historic status, and compliance with the city's solar PV standards.

Building and trade review

Projects that do not meet EZ solar standards need an Electrical Permit, a Building Permit, and submitted plans.

Call before applying when

Call before applying if the system is over the EZ threshold, on a historic property, ground-mounted, includes structural changes, or has complex interconnection requirements.
