Flower Mound, TX Solar Energy: Panel Permits (2026)

Solar panel installations in Flower Mound require both a building permit (for structural attachment) and an electrical permit (for the inverter and grid interconnection) from the Building Department. Roof-mounted photovoltaic systems must comply with the adopted International Residential Code structural requirements including roof load capacity verification and International Fire Code setback requirements that maintain clear pathways for firefighter access. Ground-mounted solar arrays must comply with Chapter 98 Zoning setback and height restrictions for the applicable zoning district and are treated as accessory structures. Interconnection with the Oncor Electric Delivery distribution system requires a separate application through the utility for net metering or distributed generation. Texas Property Code Section 202.010 provides statewide protection for solar energy device installations on single-family residential properties. Under this statute, HOAs may not include or enforce provisions that prohibit or effectively prohibit the installation of solar energy devices, though HOAs may require that panels be installed in a manner that does not void the roof warranty and may regulate placement to the extent that such regulation does not effectively prevent installation or significantly increase cost. The Building Department reviews applications for code compliance and issues permits within standard processing timelines. Contact the Building Department at (972) 874-6350 for solar permit requirements.
