Houston Solar
Permit Design.
Electrical Permit Only.
Choose Your REP First.
Houston solar permit drawings and plan sets for City of Houston and all Harris County AHJs. Houston is unique in Texas: residential solar under 50kW needs only an electrical permit — no building permit. CenterPoint handles interconnection. But your customer gets zero export credit without a solar buyback REP. Pick that first. Free for first-time clients.
No Building Permit for Residential Solar. And Without a Solar Buyback REP, Your Customer Exports for Free. Both Matter Before You Pull the First Panel.
Houston has the most permitting-friendly residential solar rules of any major Texas city — electrical permit only for systems under 50kW on existing roofs. But the deregulated ERCOT electricity market creates a trap: CenterPoint Energy owns the grid and handles interconnection, but CenterPoint does not buy excess solar generation. Your customer needs a solar buyback Retail Electric Provider (REP) enrolled before the system goes live, or every exported kilowatt-hour earns nothing.
