Why Solar + Battery Storage in Galveston?
- ●High sun exposure: Galveston averages an estimated 5.2 peak sun hours per day — strong solar production potential year-round.
- ●High local utility rates: CenterPoint Energy (TDU) customers in Galveston pay an estimated $0.14/kWh, making solar self-consumption economics strong. Galveston 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.
- ●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 Galveston-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.
