Sun on a roof in Quintana.
The PVWatts model puts a generic roof array in Quintana at 1,508 kWh a year for each kW of panels, using typical-year weather from a station 1.5 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Against Houston
The nearest of the six largest modeled places is Houston, 97 km to the north, at 1,422 kWh per kW. Quintana models 86 kWh per kW (6.0%) above it. Quintana lies 0.87 degrees of latitude south of Houston, and the sun stands higher in the sky the further south you go, which matches its higher modeled output. The two weather stations sit a similar distance from their points (1.5 km and 2.4 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Austin, 280 km northwest, where the same model gives 1,483 kWh per kW, so Quintana runs 25 above that figure. Against the Texas median place month by month, Quintana runs at least 2% higher in April, May, October. It runs at least 2% lower in January, February, June, July, September, November, December.
Electricity in Brazoria CountyEIA-861
Electricity prices nearby
EIA lists CenterPoint Energy Houston Electric and Texas-New Mexico Power in this county. Where Quintana is on CenterPoint Energy Houston Electric and Texas-New Mexico Power's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Quintana may instead be served by a co-op or utility listed below, which sets its own rates; check your bill. For scale only, the median 2025 average price across the 60 Texas retail providers on this site is 15.32¢ per kWh, which would put the modeled 1,508 kWh at $231 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Jackson Electric Coop, Inc: 14.55¢ per kWh, a bundled average, 15,670 residential customers across 6 counties.
- CenterPoint Energy: 5.41¢ per kWh, delivery charges only, before the retail energy price, 2,529,039 residential customers across 12 counties.
These utilities serve other parts of the county, which can include parts of Quintana. They are the largest bundled providers, and the largest delivery-only one, whose EIA service territory lists the county. A county can list several, and which one serves a street depends on the address, so check your bill.

Size the array, see the kWh.
Scale the Quintana model to another array size, take off extra losses for shade or dirt, and price the energy at any rate. It is arithmetic on the PVWatts output above, nothing more: not a quote, not a savings estimate and not advice.
Starting rate: the Texas residential average of 15.4¢ per kWh. At that rate the modeled output is worth $232 per kW a year as plain multiplication.

Getting a measured number
A model cannot see your roof. Installers measure pitch, shade and the electrical panel on site. Quote marketplaces such as EnergySage, SolarReviews and WattBuy collect bids from local installers. Rate & Roof does not rank installers.

The sliders above price the energy at one rate. The payback calculator adds the system cost and your buyback plan type, and shows every assumption. It is an estimate, not advice.
