Sun on a roof in Aspermont.
The PVWatts model puts a generic roof array in Aspermont at 1,672 kWh a year for each kW of panels, using typical-year weather from a station 1.1 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Against Fort Worth
The nearest of the six largest modeled places is Fort Worth, 271 km to the east, at 1,535 kWh per kW. Aspermont models 137 kWh per kW (8.9%) above it. Aspermont lies 0.36 degrees of latitude north of Fort Worth, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The two weather stations sit a similar distance from their points (1.1 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Dallas, 324 km east, where the same model gives 1,500 kWh per kW, so Aspermont runs 172 above that figure. Against the Texas median place month by month, Aspermont runs at least 2% higher in January, February, March, April, May, June, August, September, October, November, December.
Electricity in Stonewall CountyEIA-861
Electricity prices nearby
EIA lists AEP Texas North in this county. Where Aspermont is on AEP Texas North's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Aspermont 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 1,672 kWh at $256 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Tri-County Electric Coop, Inc (TX): 15.07¢ per kWh, a bundled average, 117,857 residential customers across 16 counties.
- South Plains Electric Coop Inc: 11.02¢ per kWh, a bundled average, 58,726 residential customers across 18 counties.
- Big Country Electric Coop, Inc: 13.33¢ per kWh, a bundled average, 9,533 residential customers across 12 counties.

These utilities serve other parts of the county, which can include parts of Aspermont. 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 Aspermont 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 $257 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.

Payback, buyback.
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.
