Utility Rate

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 competitive solar buyback to maximize savings. Illustrative residential rate range: $0.12-$0.16/kWh depending on REP choice.

Climate Zone
Hot-humid North Texas / Hail Alley: Hot, humid summers with high cooling demand. Tarrant County is in "Hail Alley" -- severe spring/summer hailstorms require hail-rated solar equipment. Winter storms (like Uri in February 2021) and summer heat events make battery backup valuable for grid resilience.
County Context
Tarrant County is the Fort Worth metro area, centered on Fort Worth and Arlington. The hot, humid climate drives high summer cooling loads. Located in "Hail Alley," hail-rated solar equipment is essential. Winter Storm Uri caused multi-day blackouts, highlighting the importance of battery backup for energy resilience.

Why Solar + Battery Storage in Tarrant County?
Homeowners in Tarrant County are served by Oncor (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 Tarrant 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.
