Oncor is the utility TexPTO lists for Rockwall 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).

Common rejection patterns for Rockwall County, compiled by TexPTO from permitting requirements and industry sources (not yet verified against filed rejections): 1) Oncor eTRACK rejects application if inverter is not UL 1741 (or declared as non-certified system) and applicant does not have signed Tariff Application + Interconnection Agreement; non-certified systems must use separate PDF form and contact DG Group directly; 2) Rockwall County Fire Marshal rejects site plan if it does not show NEC 690.12 rapid-shutdown boundary, does not depict 3-foot ridge/valley setbacks per 2015 IFC, or lacks fire-access pathway clearance; plan resubmission triggers 10–14 day re-review cycle; 3) PE-stamped structural letter rejected if engineer is not Texas-licensed or if letter does not address ASCE 7 wind uplift for Rockwall County's design wind speed (inland North Texas ~90–100 mph); manufacturer racking specs alone may not satisfy if county requires explicit PE seal. Avoid these on your first submittal to skip a 7–14 day correction cycle.
