Full Breakdown
Under the Philadelphia Fire Code, Section F-105.9.12, a construction permit is required to install or modify any solar photovoltaic power system, issued through the Department of Licenses and Inspections. Beyond the permit itself, the Zoning Code sets physical standards for the equipment: roof-mounted solar collectors and their support structures are allowed as accessory structures in every zoning district, but the support structure can't exceed 9 ft. above the roof surface unless the building's total height with the collector stays under the zoning district's maximum. Ground-mounted collectors must sit in side or rear yards, capped at 20 ft. tall at maximum tilt, and in Residential districts their combined surface area can't exceed 1,000 sq. ft. per lot.
Violations & Fines
Installing or modifying panels without the required Licenses & Inspections construction permit is a Fire Code violation; ground- or roof-mounted collectors that exceed the height, setback, or area limits also violate the Zoning Code.
