Municipal roofs, residential retrofits, and the sheets behind them.

More than 4,000 permitted projects have gone out of this office. Below is a cross-section — built systems, design models and the sealed drawing sheets that got them through review.

01 / Case study

Orlando Fire Station 6

A 142 kW rooftop array on an operating fire station. Because a fire station is an essential facility, 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, with fire-rated penetration details drawn for every conduit that crosses the apparatus bay wall, and a data logger tied back to the station IT room.

02 / Built work

Systems on Florida roofs.

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

Residential

Standing-seam metal roof array

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

Residential

Two-orientation shingle roof array

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

03 / Drawings

The part your reviewer actually reads.

Photographs sell the finished job. These sheets are what decides whether the permit clears on the first pass.

Electrical one-line diagram with conduit schedule, voltage drop calculations and label details — **Electrical diagram — Orlando Fire Station 6.** Full one-line from modules to the 800 A service, with conduit schedule, DC and three-phase AC voltage-drop calculations, OCPD sizing checks against NEC 690.8(B), and every required label drawn with its type and location.

Equipment elevation sheet showing inverter layout and fire barrier penetration details — **Equipment elevations — sheet E-03.** Inverter and disconnect elevations inside the apparatus bay, IT room data logger, exterior service entrance, plus two detail callouts 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 individually tagged — **Estate isometric.** Twenty-three separate 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, modelled 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 interconnection method before the set is drawn.

04 / Deliverable

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 is consistent, so your permit runner always knows where to look.
