County-Specific Requirements
Orange County uses e-permitting for solar applications at ocfl.net. Duke Energy Florida serves most of the county — submit the Duke DER interconnection application at duke-energy.com simultaneously with your county permit. A portion of Orlando is served by OUC (Orlando Utilities Commission), a municipal utility with its own interconnection process at ouc.com. Confirm your utility from your electric bill before filing any applications.
Required Permit Documents
- Completed permit application — from Orange County Building Division
- Site plan — overhead drawing, to-scale, showing panels, north arrow, setback dimensions
- Roof plan with panel layout — IFC fire setbacks (18-inch perimeter; 36-inch hip-to-ridge on hip roofs)
- Single-line electrical diagram (SLD) — all equipment by make, model, and ratings
- Equipment spec sheets — panels, inverter, racking
- Structural engineering letter — typically required over 10kW; confirm with your AHJ
- Permit fee — $200–$600 (verify current schedule with AHJ before submitting)
Utility Interconnection
Duke Energy Florida requires a Distributed Energy Resource (DER) Interconnection Application submitted at duke-energy.com before or concurrent with your county permit. Duke's process includes a technical review (typically 15–20 days) and a final review after the county inspection. Timeline to PTO: 15–30 business days post-final inspection. Florida's retail-rate net metering applies to Duke Energy Florida customers.
Filing your utility interconnection application the same day as your AHJ permit application runs both reviews in parallel — saving 3–6 weeks of total timeline to Permission to Operate.

Ask your installer for the permit application or record number. Use that number to search the permit status at the Orange County Building Division online portal, or call (407) 836-5550. You want to see the permit listed as "issued" (approved) and eventually "finaled" (final inspection passed). The utility will not issue PTO until the permit is finaled — a permit stuck at "issued" means the process is not complete.
This is an unfortunately common situation. As the permit holder (the permit is in your name as property owner), you can contact Orange County Building Division directly to understand the permit's status and options for completing the required inspections with a different licensed contractor. You will need a licensed electrician or solar contractor to complete any outstanding work and schedule the remaining inspections. Keep all original permit documents and equipment spec sheets — you'll need them for the replacement contractor.
No — adding battery storage after the initial solar installation requires a new permit in most jurisdictions, including Orange County (Orlando Metro). Battery energy storage systems require their own permit under NEC Article 706 covering the battery enclosure, electrical connections, and ventilation requirements. If you anticipate adding storage within a few years, discuss this with your installer upfront — some jurisdictions allow a combined solar + storage permit that can reduce total permitting cost and complexity.
