Sun on a roof in Von Ormy.
The PVWatts model puts a generic roof array in Von Ormy at 1,520 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 San Antonio
The nearest of the six largest modeled places is San Antonio, 24 km to the northeast, at 1,505 kWh per kW. Von Ormy models 15 kWh per kW (1.0%) above it. At 0.18 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The weather station for Von Ormy is 1.1 km from the modeled point, against 2.2 km for San Antonio, so part of the gap can come from which station's typical year was used.
The second-nearest large place is Austin, 143 km northeast, where the same model gives 1,483 kWh per kW, so Von Ormy runs 37 above that figure. Against the Texas median place month by month, Von Ormy runs at least 2% higher in January, August, October, November, December. It runs at least 2% lower in February, April, May.

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 1,520 kWh would come to $188 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Von Ormy 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 $234 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.
