Contractor cover letter that introduces the submittal package to the plan reviewer. Editable before sending.
Richardson 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.
Richardson note: Richardson requires a TX-licensed PE seal on structural letters. Upload the PE-sealed PDF here. TexPTO does not generate engineering opinions.
PE-stamped structural drawings showing roof framing, attachment locations, and load path.
Richardson note: Provided by your licensed PE.
PE-stamped electrical drawings including single-line diagram, wiring layout, and disconnect locations.
Richardson note: Richardson requires a SEPARATE electrical permit in addition to the building permit. Both reference the same stamped drawings; you'll just file two applications.
Manufacturer datasheets for panels, inverters, and (if applicable) batteries.
Richardson 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.
Richardson 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 Richardson's permit portal. Print or keep on a second monitor while submitting.
Richardson note: Multi-family / townhome / condo installs in Richardson route through a different review track (HOA + city) than single-family — confirm the permit type before submitting.
AI-drafted letter to the homeowner's HOA requesting approval for the solar installation. Review, edit, and sign before sending.
Richardson note: Varies by subdivision in Richardson. Check deed restrictions.
AI-drafted one-page narrative summarizing the project for the permit reviewer. Attach to submittal or paste into portal text areas.
Richardson 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).
Richardson note: Tailor the blurb to Richardson's portal field length if needed — some portals cap at 250 chars, others allow a paragraph.
The most frequent reasons Oncor or Richardson kicks back a residential solar permit. Avoid these on your first submittal to skip a 7–14 day correction cycle.
