Round Rock TX solar panel permit rules
City of Round Rock Building & Standards requires a building permit and an electrical permit for rooftop solar PV installations. Apply via roundrocktexas.gov. Texas has no state GC or solar contractor license requirement. A TDLR TECL-licensed electrician must pull the electrical permit (tdlr.texas.gov). Call (512) 218-5500 to confirm current documentation requirements before submitting.
Oncor, as the Transmission and Distribution Utility for Round Rock 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 1-888-554-4732 (Oncor) or 888-554-4732 (PEC) 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.
