Contractor cover letter that introduces the submittal package to the plan reviewer. Editable before sending.
Plano 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.
Plano note: Plano requires the PE letter explicitly call out UL-listed racking and attachment hardware. Have your PE verify module clips match the manufacturer's load table for Plano's 90mph design wind speed before stamping.
PE-stamped structural drawings showing roof framing, attachment locations, and load path.
Plano note: Provided by your licensed PE.
PE-stamped electrical drawings including single-line diagram, wiring layout, and disconnect locations.
Plano note: Provided by your licensed PE.
Manufacturer datasheets for panels, inverters, and (if applicable) batteries.
Plano 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.
Plano 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 Plano's permit portal. Print or keep on a second monitor while submitting.
Plano note: Plano uses its eTRAKiT portal. Search by address, not permit type — the portal's permit-type picker has a separate 'Solar (PV)' category that's easy to miss.
AI-drafted letter to the homeowner's HOA requesting approval for the solar installation. Review, edit, and sign before sending.
Plano note: Commonly required in Plano — check the subdivision's deed restrictions before skipping.
AI-drafted one-page narrative summarizing the project for the permit reviewer. Attach to submittal or paste into portal text areas.
Plano 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).
Plano note: Tailor the blurb to Plano's portal field length if needed — some portals cap at 250 chars, others allow a paragraph.
Roof-plan diagram showing 3' minimum setbacks from ridge and eaves, per Plano's adopted IRC fire-access amendment for PV arrays on rooftops.
Plano note: Plano's Fire Marshal separately reviews fire-access pathways on most residential solar permits. Include this in your initial submittal to avoid a correction loop.
The most frequent reasons Oncor or Plano kicks back a residential solar permit. Avoid these on your first submittal to skip a 7–14 day correction cycle.
