Submittal requirements

10 items

  1. #1

    Project Permit Transmittal Letter

    Contractor cover letter that introduces the submittal package to the plan reviewer. Editable before sending.

    Carrollton note: Carrollton straddles Dallas, Denton, and Collin counties. The fee schedule differs by county — confirm the permit-desk has the correct county code for the service address before submittal.

  2. #2

    Stamped Engineer Letter (PE-sealed)

    Licensed Professional Engineer's letter attesting to structural adequacy of the roof for the proposed PV array.

    Carrollton note: Carrollton requires a TX-licensed PE seal on structural letters. Upload the PE-sealed PDF here. TexPTO does not generate engineering opinions.

    Upload required

    PE-stamped structural drawings showing roof framing, attachment locations, and load path.

    Carrollton note: Provided by your licensed PE.

  5. #5

    Solar Panel Specifications (Cut Sheets)

    Manufacturer datasheets for panels, inverters, and (if applicable) batteries.

    Carrollton note: If the project is an ADDITION to an existing PV system, Carrollton wants as-built documentation of the existing system (previous permit number, existing system size) attached to the cut-sheets bundle.

    Compiled from sources
  6. #6

    NEC Warning Labels

    NEC-mandated placards (rapid shutdown, PV disconnect, dual power source, etc.) sized for label printing. Requires DC voltage/current values from your design.

    Carrollton 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.

  7. #7

    Portal Submission Cheat Sheet

    One-page reference with values to paste into Carrollton's permit portal. Print or keep on a second monitor while submitting.

    Carrollton note: Not a substitute for submission — installer still types values into the portal manually. TexPTO does not automate portal submissions.

  8. #8

    HOA Approval Request Letter (draft)

    AI-drafted letter to the homeowner's HOA requesting approval for the solar installation. Review, edit, and sign before sending.

    Carrollton note: Commonly required in Carrollton — check the subdivision's deed restrictions before skipping.

    Template-drafted
  9. #9

    Project Narrative (draft)

    AI-drafted one-page narrative summarizing the project for the permit reviewer. Attach to submittal or paste into portal text areas.

    Carrollton note: Always review the AI output before including in submittal.

  10. #10

    Portal 'Description of Work' Blurb (draft)

    Short AI-drafted blurb sized to paste into the AHJ portal's Description of Work field (typically 150-250 words).

    Carrollton note: Tailor the blurb to Carrollton's portal field length if needed — some portals cap at 250 chars, others allow a paragraph.
