Do I need a permit for solar panel installation in Lower Merion?
Yes. In Pennsylvania, solar panel installation generally requires a permit, and Lower Merion is no exception.
Under the Pennsylvania UCC a rooftop solar system is an alteration plus electrical-system work, so it requires a permit and both structural and electrical review. Ground-mounts add their own foundation and setback review. The permit covers code compliance only. Your electric utility runs a separate interconnection and net-metering approval. Confirm both with your local code office and utility. Lower Merion issues solar panel permits through its online permitting portal and requires separate building and electrical permits for a solar installation. Electrical work is verified by a Township-approved third-party electrical inspection agency; a certificate of inspection must be furnished to the Code Official within 15 days of completion. Ground-mounted arrays and roof arrays visible from a public way in a historic district may require HARB review. Confirm with Lower Merion Building & Planning at 610-645-6200.
