Lewisville TX solar panel permit rules

Texas has no state GC or solar contractor license requirement. A TDLR TECL-licensed electrician must pull the electrical permit (tdlr.texas.gov).

Oncor, as the Transmission and Distribution Utility for Lewisville in ERCOT's deregulated market, requires a separate interconnection application for solar systems connected to the grid. The interconnection process is distinct from your Retail Electric Provider's net-metering agreement — contact Oncor at 1-888-313-4747 for interconnection requirements. Net metering terms vary by REP — compare REP solar tariffs before selecting your Retail Electric Provider. Texas has no state-mandated solar access law equivalent to California's, but local HOA restrictions may apply — verify HOA rules before installation.
