Contractor cover letter that introduces the submittal package to the plan reviewer. Editable before sending.
Coppell note: This is the installer's cover letter — not a PE-stamped engineering document. Any engineering opinion is provided separately by your licensed PE.
Licensed Professional Engineer's letter attesting to structural adequacy of the roof for the proposed PV array.
Coppell note: Coppell's plan reviewer routinely asks for a 1.5x safety-factor analysis from the PE on older roofs (20+ years). Include the rafter size/spacing + attachment spec in the letter up front.
PE-stamped structural drawings showing roof framing, attachment locations, and load path.
Coppell note: Provided by your licensed PE.
PE-stamped electrical drawings including single-line diagram, wiring layout, and disconnect locations.
Coppell note: Provided by your licensed PE.
Manufacturer datasheets for panels, inverters, and (if applicable) batteries.
Coppell note: Upload each manufacturer datasheet. The submittal package concatenates them in order.
NEC-mandated placards (rapid shutdown, PV disconnect, dual power source, etc.) sized for label printing. Requires DC voltage/current values from your design.
Coppell note: The generator will fail safely if the DC max voltage and max current aren't known — you'll be prompted to provide them. Use the 'Edit specs' button on this row to override extracted values.
One-page reference with values to paste into Coppell's permit portal. Print or keep on a second monitor while submitting.
Coppell note: Not a substitute for submission — installer still types values into the portal manually. TexPTO does not automate portal submissions.
AI-drafted letter to the homeowner's HOA requesting approval for the solar installation. Review, edit, and sign before sending.
Coppell note: REQUIRED for Coppell — every residential subdivision is HOA-governed. Do not submit without HOA approval in hand.
AI-drafted one-page narrative summarizing the project for the permit reviewer. Attach to submittal or paste into portal text areas.
Coppell note: Always review the AI output before including in submittal.
Short AI-drafted blurb sized to paste into the AHJ portal's Description of Work field (typically 150-250 words).
Coppell note: Tailor the blurb to Coppell's portal field length if needed — some portals cap at 250 chars, others allow a paragraph.
Roof-plan diagram with a 3' pathway on both sides of the ridge for the fire department. Coppell's code amendment is stricter than base IRC.
Coppell note: Coppell enforces pathway-on-both-sides strictly. Arrays that pack all modules to one side of the ridge will bounce.
The most frequent reasons Oncor or Coppell kicks back a residential solar permit. Avoid these on your first submittal to skip a 7–14 day correction cycle.
