Lewisville, TX Solar Energy: Panel Permits (2026)

Lewisville requires both a building permit and an electrical permit for residential solar panel installations. Applications are submitted through the Inspections Division at (972) 219-3480. Rooftop systems must meet structural load requirements under the International Residential Code as adopted by the city, ensuring the roof structure can support the additional weight of panels, racking, and ballast. Electrical work must comply with the National Electrical Code including rapid shutdown requirements for rooftop systems. Roof-mounted panels must maintain fire code setbacks from roof edges, ridges, and valleys to provide firefighter access. Ground-mounted solar arrays must comply with accessory structure setback requirements and cannot be placed in front yards or required setbacks. Texas Property Code Section 202.010 prohibits property owners associations from banning solar energy devices entirely. HOAs may only impose reasonable restrictions that do not increase installation cost by more than 10% or decrease system efficiency by more than 10%. Texas Tax Code Section 11.27 provides a property tax exemption for the appraised value added by solar energy devices. CenterPoint Energy and CoServ Electric (the primary utilities serving Lewisville) offer interconnection for grid-tied solar systems. Net metering or value-of-solar tariffs vary by utility provider. Contact the Inspections Division for current permit fees and plan review timelines.
