County Snapshot — Dallas County

Utility Rate

Oncor (TDU): Estimated $0.14/kWh residential rate. Dallas County is in the deregulated ERCOT market. Oncor delivers power as the wires-only 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 competitive solar buyback to maximize savings. Illustrative residential rate range: $0.12-$0.16/kWh depending on REP choice.

Permit Office

Dallas Development Services (City of Dallas (other cities and unincorporated areas have separate processes)). Typical turnaround: 2-6 weeks, varies by jurisdiction. Dallas and other incorporated cities in Dallas County each have their own building departments. Permit timelines vary by jurisdiction -- confirm with your local building department. Your installer manages the application.

Climate Zone

Hot-humid North Texas / Hail Alley: Hot, humid summers with high cooling demand. Dallas is part of "Hail Alley" -- severe spring/summer hailstorms are common, requiring hail-rated solar equipment. Winter Storm Uri (February 2021) caused multi-day blackouts. Battery backup is valuable for both winter storms and summer heat events.

County Context

Dallas County is the urban core of North Texas, centered on Dallas and surrounding cities. The hot, humid climate drives high summer cooling loads. Dallas sits in "Hail Alley" -- hail-rated solar equipment is essential. Winter Storm Uri underscored the importance of battery backup for grid resilience during extreme weather events.

Why Solar + Battery Storage in Dallas County?

Homeowners in Dallas County are served by Oncor (TDU) / Garland Power & Light (municipal), 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 Dallas 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.
