Sun on a roof in Littlefield.
The PVWatts model puts a generic roof array in Littlefield at 1,755 kWh a year for each kW of panels, using typical-year weather from a station 1.4 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Against El Paso
The nearest of the six largest modeled places is El Paso, 447 km to the southwest, at 1,835 kWh per kW. Littlefield models 80 kWh per kW (4.4%) below it. Littlefield lies 2.07 degrees of latitude north of El Paso, and the sun stands higher in the sky the further south you go, which matches its lower modeled output. The two weather stations sit a similar distance from their points (1.4 km and 0.9 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Fort Worth, 480 km east, where the same model gives 1,535 kWh per kW, so Littlefield runs 220 above that figure. Against the Texas median place month by month, Littlefield runs at least 2% higher in January, February, March, April, May, June, July, August, September, October, November, December.

Providers listed in the county
- Southwestern Public Service Co: 13.94¢ per kWh, a bundled average, 223,685 residential customers across 45 counties.
- South Plains Electric Coop Inc: 11.02¢ per kWh, a bundled average, 58,726 residential customers across 18 counties.
- Bailey County Elec Coop Assn: 9.82¢ per kWh, a bundled average, 3,461 residential customers across 5 counties.
They are the largest bundled providers 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. Priced at the first provider's average, the modeled 1,755 kWh would come to $245 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Littlefield 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 $270 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.
