Going solar in Ohio: the process
1. Pick a licensed installer. Ohio requires installers to hold a Ohio Electrical Contractor License (Electrical (state) + local) issued by Ohio Construction Industry Licensing Board (OCILB) — Electrical Section. Always verify your contractor's license is active before signing.
2. Sign the contract and submit permits. Columbus, Cleveland, Cincinnati, Toledo, and Akron each have their own permit submission processes. Most municipalities process within 10–25 business days.
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). Ohio EDC interconnection follows PUCO Standardized Interconnection Procedures. Residential systems are typically reviewed within 30–45 days of complete application.
Total typical timeline: 6–12 weeks from contract to PTO.
