San Antonio requires a building permit for residential solar panel installations. Most jurisdictions have adopted streamlined or expedited permitting for standard rooftop solar systems. Plans must show panel layout, structural capacity of the roof, electrical interconnection, and setbacks from roof edges. Electrical permits cover the inverter, disconnect, and utility interconnection. Net metering agreements with the local utility allow credited excess generation. Solar access laws in many states protect existing solar installations from new shading by neighboring properties or structures. Ground-mounted systems may face additional zoning setback requirements.
