Why Solar + Battery Storage in Denton County?
Homeowners in Denton County are served by Denton Municipal Electric (municipal) / 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 Denton 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.
