What Un-incorporated Pinellas expects on a solar permit
Structural designs must utilize 150 mph wind speed, Exposure B, and Risk Category II per FBC 2023 and ASCE 7-22. Installers must provide an engineer's letter or special inspection report verifying at least 3-inch lag screw embedment into trusses. Battery systems must be configured as Partial Home Backup, as Whole Home Backup is not allowed. Documentation must include a Back Up Load Analysis form, PE-stamped load calculations per NEC 220.83, and certifications referencing Florida Statute 377.705. Additional requirements include reflective PV labels, specific fire access pathways, and interconnected heat alarms for ESS installations in attached garages.
- [calcs] Total backup load must not exceed battery capacity per NEC 702.4; the AHJ explicitly notes that NEC 710 references do not supersede this requirement.
- [calcs] Battery power capacity must exceed the single largest load on site, including motor inrush current (LRA), per NEC 710.15(a).
- [calcs] Provide PE-stamped load calculations in KW per NEC 220.83 Optional Method; kWh-only calculations are not accepted for battery systems.
- [documentation] Provide a 'Back Up Load Analysis' form detailing breaker size, kW, inrush current (LRA), running load (RLA), and nameplate/model details for all motor or furnace loads.
- [structural] Structural designs must use 150 mph wind speed, Exposure B, Risk Category II per FBC 2023 / ASCE 7-22.
- [electrical] Whole Home Backup (WHB) is not allowed; battery systems must be configured as Partial Home Backup (PHB).
- [documentation] Submit an Application for Construction in a Floodplain, FEMA Cost Breakdown Worksheet, and Substantial Improvement Disclosure Form for properties located in a flood zone.
- [fire] Install interconnected listed heat alarms in attached garages where ESS is installed per NFPA 855 (2020) 15.9.2.
- [fire] Provide at least two 36-inch wide fire access pathways from gutter to ridge, with one located on the street or driveway side.
- [labeling] PV labels must be reflective with a minimum letter height of 3/8 inch per NFPA 1.
- [documentation] Electrical and structural certifications must explicitly reference Florida Statute 377.705.
- [structural] Provide an engineer's letter of compliance or special inspection report verifying lag screws have at least 3-inch embedment into trusses.
- [electrical] Provide a detailed explanation of the PV connection method and cite specific code sections (e.g., NEC 705) for load-side taps.
- [labeling] Label the disconnect specifically as 'AC Disconnect'.
- [calcs] Energy storage sizing must include a 'days of autonomy' factor (e.g., 1 or 2 days) to determine minimum kWh capacity.
- Repeated rejections for the same issue are subject to a 4x fee ($500) per FS 553.80.
