Common rejection reasons

AI-researched, not yet verified

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

  • PE-stamped structural letter does not reference specific roof type, racking system, or ASCE 7-16/7-22 edition — Lowry Crossing Building Inspector requires all three details before acceptance
  • Single-Line Diagram lacks facility study reference or TNMP study number — PowerClerk rejects incomplete SLDs; installer must reference pre-interconnection study findings before final approval
  • Site Plan setbacks do not comply with IRC and IFC 3-foot fire-access pathway spacing — confirm Lowry Crossing has not published supplemental setback requirements; apply IRC minimum and allow inspector to waive if needed
  • NEC 690/705 label placement does not match NEC 2020 wording or placement locations — City Inspector rejects non-compliant labeling; confirm adopted code cycle with City Hall before submitting
  • Manufacturer cut sheets do not show UL 1741 SA listing (inverter) or UL 61730/1703 listing (modules) — TNMP PowerClerk flags missing or non-compliant certifications; obtain current spec sheets directly from manufacturer
  • Oncor DG Portal account not yet active — contractor must email dg@oncor.com to request eTRACK access before submitting DG interconnection application; registration can delay by 3-5 business days
  • Customer does not confirm PowerClerk authorization email within 5 business days — application goes dormant; installer must remind customer to check inbox and click confirmation link to restart TNMP review clock
