Going solar in Pennsylvania: the process
1. Pick a licensed installer. Pennsylvania requires installers to hold a Home Improvement Contractor (HIC) + municipal electrical license (Home Improvement Contractor + Electrical (municipal)) issued by PA Office of Attorney General + local municipal licensing boards. Always verify your contractor's license is active before signing.
2. Sign the contract and submit permits. Permit timelines range widely. Philadelphia and Pittsburgh have online portals and typically 15–30 day timelines. Smaller jurisdictions can be faster or slower.
3. Installation. Most residential rooftop installs take 1–3 days of on-site work. Your contractor coordinates the timing and any roof staging.
4. Final inspection. The local AHJ inspects your install. Once passed, your installer submits the interconnection application to your utility.
5. Permission to Operate (PTO). PECO, PPL, Duquesne Light, Met-Ed, Penelec, West Penn Power, and other Pennsylvania EDCs each have similar Standardized Interconnection Procedures. Most residential systems are reviewed within 30–60 days.
Total typical timeline: 6–12 weeks from contract to PTO.
