County Snapshot — Harris County
Utility Rate
CenterPoint Energy (TDU): Estimated $0.14/kWh residential rate. Harris County is in the deregulated ERCOT market. CenterPoint Energy delivers power as the wires-only Transmission and Distribution Utility (TDU), but you choose your own Retail Electric Provider (REP) which sets your solar buyback rate. Solar export rates vary widely by REP and plan -- shop for a REP with a competitive solar buyback plan to maximize your savings. Illustrative residential rate range: $0.12-$0.16/kWh depending on REP and plan choice.
Permit Office
City of Houston Permitting Center (City of Houston (unincorporated areas via Harris County)). Typical turnaround: 2-6 weeks, varies by jurisdiction. Houston and other incorporated cities in Harris County each have their own building departments. Permit timelines vary -- confirm with your local jurisdiction. Your installer manages the application.
Climate Zone
Hot-humid Gulf Coast climate: Hot, humid summers with frequent afternoon thunderstorms. High cooling demand from May through September. Hurricane and tropical storm risk requires wind-rated equipment. Coastal humidity and salt air require corrosion-resistant hardware. Battery backup is valuable for multi-day post-storm outages.
County Context
Harris County is the most populous county in Texas, centered on Houston and spanning the Gulf Coast flatlands. The hot, humid climate drives high summer cooling loads, making solar highly valuable for offsetting air conditioning costs. Winter Storm Uri (February 2021) caused multi-day statewide blackouts, underscoring the importance of battery backup for grid resilience. Hurricane preparedness is a priority -- solar + battery systems provide critical backup power during multi-day post-storm outages.

Why Solar + Battery Storage in Harris County?
Homeowners in Harris County are served by CenterPoint Energy (TDU), which has seen significant residential rate increases in recent years. Residential solar + battery storage offers a way to lock in energy costs at installation prices and protect against future rate hikes.
A solar + battery system combines rooftop panels, battery storage, and inverters to power your home's biggest loads — heating, cooling, and major appliances — while maximizing the power you make and use yourself, plus backup power during grid outages. A licensed local installer sizes and installs the system.
Most of Texas is a deregulated ERCOT market, so solar export (buyback) rates depend on the Retail Electric Provider and plan you choose — they can vary widely. In Harris County, the reliable value is in storing and using your own power rather than depending on a favorable buyback rate. Ask your local installer about current interconnection and buyback options for your utility.
