Design model of the 142 kW rooftop array across the main station roof and apparatus bay at Orlando Fire Station 6
Design modelMain station + apparatus bay

01 · Case study

Orlando Fire Station 6

A 142 kW rooftop array on an operating fire station. A fire station is an essential facility, so the whole set is designed to Risk Category IV, the strictest loading class in the code, at 140 mph design wind over a TPO membrane roof.

Four SolarEdge inverters feed an AC accumulation panel. Every conduit that crosses the apparatus bay wall gets a fire-rated penetration detail, and a data logger ties back to the station IT room.

  • 142.27 kW DC
  • 112.7 kW AC
  • 347 modules
  • Risk Cat. IV

Systems on Florida roofs.

Every array below was permitted from a set drawn and sealed in this office.

Standing-seam metal roof array

A full-slope, all-black array covering the entire south face of a Miami-Dade residence. It is clamped directly to the standing seams, so the roof was never penetrated and the manufacturer warranty stayed intact.

Two-orientation shingle roof array

A composition-shingle roof split across two orientations and boxed in by mature tree cover. The shade study drove the layout: modules only where they actually produce.

Photographs sell the finished job. These sheets decide whether the permit clears on the first pass.

Electrical one-line diagram for Orlando Fire Station 6 with conduit schedule, voltage-drop calculations and label details
Electrical diagram · Orlando Fire Station 6 Full one-line from the modules to the 800 A service, with conduit schedule, DC and three-phase AC voltage-drop calculations, OCPD sizing checked against NEC 690.8(B), and every required label drawn with its type and location.
Sheet E-03 showing inverter and disconnect elevations and fire barrier penetration details
Equipment elevations · Sheet E-03 Inverter and disconnect elevations inside the apparatus bay, the IT room data logger and the exterior service entrance, plus two details for fire-rated conduit penetrations through the existing concrete wall.
Residential system riser diagram with microinverter circuits and a 200 amp combiner panel
Residential riser diagram Seven microinverter circuits into a 200 A combination panel with surge protection, a 175 A fused AC disconnect, and a line-side tap detailed at the existing 200 A service.
Isometric drawing of an estate with twenty-three module rows, each tagged with module and mount counts
Estate isometric Twenty-three module rows across a multi-level roof, each tagged with its module and mount count, so the crew can stage hardware row by row instead of guessing.
Design model of a 96-module array across two commercial buildings
Commercial design model A 96-module array laid across a hip roof and an adjacent outbuilding, modeled before layout to confirm setbacks and walkways.
Annotated sample riser diagram with a wiring schedule
Annotated sample The reference riser I share with contractors, so everyone agrees on conductor sizes and the interconnection method before the set is drawn.

What arrives in your inbox.

A single sealed PDF, sheet-numbered and ready to upload to the AHJ portal.

Sheet count varies with scope. A simple residential retrofit runs lighter than an essential-facility commercial array, but the structure stays the same, so your permit runner always knows where to look.
