Submittal requirements

11 items

  1. #1

    Stamped Engineer Letter

    Licensed PE letter attesting to structural adequacy of the roof for the proposed PV array.

    Frisco note: We produce a draft; your licensed PE reviews, signs, and seals before submission.

    Template-drafted
  2. #1

    Project Permit Transmittal Letter

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

    Frisco note: This is the installer's cover letter — not a PE-stamped engineering document. Any engineering opinion is provided separately by your licensed PE.

    Auto-generated
  3. #2

    Stamped Engineer Letter (PE-sealed)

    Licensed Professional Engineer's letter attesting to structural adequacy of the roof for the proposed PV array. Provided by your engineer of record.

    Frisco note: Required if the jurisdiction or structural review calls for a sealed letter. Upload the PE-sealed PDF here. TexPTO does not generate engineering opinions.

    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.

    Frisco note: The generator will fail safely if the DC max voltage and max current aren't known — you'll be prompted to provide them.

    Portal Submission Cheat Sheet

    One-page reference with all the values you'll need to type into Frisco's AvolveCloud portal. Print or keep on a second monitor while submitting.

    Frisco note: Not a substitute for submission — installer still types values into the portal manually. Full portal automation is a larger future project.

Common rejection reasons

The most frequent reasons Oncor or Frisco kicks back a residential solar permit. Avoid these on your first submittal to skip a 7–14 day correction cycle.

  • Module/inverter mismatch between plans and spec sheets
  • Missing required safety placard content
  • Incomplete roof/array layout fire-access dimensions
  • Missing Rapid Shutdown placard (NEC 690.12)
  • VLLD distance exceeded (>10 ft Oncor limit)
  • Missing meter or disconnect photo documentation
