Why Solar + Battery Storage in Grand Prairie?
- ●High sun exposure: Grand Prairie averages an estimated 5.3 peak sun hours per day — strong solar production potential year-round.
- ●High local utility rates: Oncor (TDU) customers in Grand Prairie pay an estimated $0.14/kWh, making solar self-consumption economics strong. Tarrant 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 competitive solar buyback to maximize savings. Illustrative residential rate range: $0.12-$0.16/kWh depending on REP choice.
- ●Deregulated market choice: across most of Texas you pick your Retail Electric Provider, and solar buyback rates vary widely by plan — so the reliable value is in storing and using your own power. Ask your local installer about current federal and state incentives; consult a tax professional for your situation.
- ●Home value: Studies suggest homes with owned solar systems sell for more than comparable homes without — though results vary by market.

When the grid goes down, your lights stay on
Winter Storm Uri and hurricane-season outages have left Grand Prairie-area homes without power for hours — sometimes days. A solar + battery system keeps your fridge, lights, and Wi-Fi running while the grid is down. No generator, no fuel runs, no scramble.
