Solar permitting and interconnection in Florida

The building permit

Rooftop solar is a structural and electrical modification to your home, so it is permitted and inspected like other construction work. The review covers the array’s wind loading, the attachment method, and the electrical design including how generation is connected to your panel.

Requirements and turnaround differ by jurisdiction, and the difference is real: two neighbouring Florida cities can vary substantially in both. In Miami-Dade and Broward, the High-Velocity Hurricane Zone applies stricter product approval and inspection requirements, which affects both the hardware that may be used and the documentation the installer must produce.

The interconnection agreement

Separately, your utility must agree to connect the system. For investor-owned utility customers this runs under Florida PSC Rule 25-6.065, which sets the tier structure and the requirement that the system is not expected to produce more than 115% of annual consumption. Municipal utilities and cooperatives run their own processes, which can differ in both requirements and speed.

Permission to operate — the utility’s final sign-off — usually comes after both the inspection and the utility’s own review. Until it arrives, a fully installed system stays switched off.

What actually causes delay

• Incomplete applications sent back for correction, which is the most common cause and entirely within the installer’s control.
• Electrical panel issues discovered late, particularly where a service upgrade turns out to be required.
• Inspection scheduling and re-inspection after a correction.
• Utility review queues, which lengthen when local demand spikes — typically after a major storm.
• HVHZ documentation requirements catching out installers who mainly work elsewhere in the state.
