Common rejection reasons

AI-researched, not yet verified

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

  • Oncor rejects Interconnection Agreement if SLD does not include Voltage Level Line Diagram (VLLD) as a separate diagram showing customer-to-utility meter interface — ensure VLLD is explicitly labeled and uploaded in eTRACK Placards section
  • Ellis County AHJ requires PE-stamped structural letter from Texas-licensed Professional Engineer (PE) confirming ASCE 7-16 wind load compliance (115 mph design wind speed for Waxahachie area) — missing or unsigned letter is a hard block; manufacturer racking letters do not substitute
  • SLD submitted to both AHJ and Oncor must show identical equipment (make, model, serial/part number for inverter, modules, disconnects, and breakers) — mismatches between AHJ submittal and Oncor eTRACK trigger revisions at both agencies
  • HOA (BridgeWater or Myrtle Creek) rejects application if ACC form not submitted BEFORE AHJ permit application — reversing order can trigger stop-work; also confirm subject property division for multi-division HOAs to cite correct CC&R sections
  • Oncor eTRACK application blocked if inverter is not UL-1741 Utility Interactive certified — non-certified systems must use separate PDF form and follow large-DG track with relay settings submission and witness test, adding 21–30 days
  • Ellis County floodplain development permit required if property is in SFHA (Special Flood Hazard Area per NFIP) — ground-mounted arrays or installations with land disturbance must include elevation certificate; Ellis County Engineer's Office must pre-approve drainage if >1 acre disturbed or culvert relocation needed
  • Oncor Certificate of Insurance (ACORD 25) naming Oncor as additional insured must be current at Interconnection Agreement execution and PTO issuance — lapsed or non-current insurance halts eTRACK approval and PTO grant

Which utility handles interconnection in Ellis County?

Oncor is the utility TexPTO lists for Ellis County, but other utilities may serve parts of the area — for a specific address, confirm the utility with your meter or a recent bill (the utility is the company that delivers power to this address, which may not be the one that bills you). Residential solar systems typically need both a permit from the permitting authority (where one is required) AND an interconnection agreement from the serving utility before the utility grants Permission to Operate (PTO).
