Solar panel building permit and Oncor interconnection path

City of Dallas solar checklist says a building permit and an electrical permit are required for flush-mounted or tilt-up photovoltaic systems. Oncor separately describes a residential distributed generation interconnection workflow where the installer files an application, Oncor reviews the project, an interconnection agreement is signed, and Permission To Operate is issued before meter programming. Residential solar projects should confirm both the City permit and Oncor interconnection paths before operation.
