Sun on a roof in Horizon City.
The PVWatts model puts a generic roof array in Horizon City at 1,883 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 El Paso
The nearest of the six largest modeled places is El Paso, 30 km to the northwest, at 1,835 kWh per kW. Horizon City models 48 kWh per kW (2.6%) above it. At 0.17 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The two weather stations sit a similar distance from their points (1.5 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 San Antonio, 774 km east, where the same model gives 1,505 kWh per kW, so Horizon City runs 378 above that figure. Against the Texas median place month by month, Horizon City runs at least 2% higher in January, February, March, April, May, June, July, August, September, October, November, December.

Providers listed in the county
- El Paso Electric Co: 13.86¢ per kWh, a bundled average, 320,320 residential customers across 3 counties.
- Rio Grande Electric Coop, Inc: 18.29¢ per kWh, a bundled average, 9,371 residential customers across 18 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 1,883 kWh would come to $261 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Horizon City 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 15.47¢ per kWh. At that rate the modeled output is worth $291 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.
