Sun on a roof in Bulverde.
The PVWatts model puts a generic roof array in Bulverde at 1,484 kWh a year for each kW of panels, using typical-year weather from a station 1.0 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, 36 km to the south, at 1,505 kWh per kW. Bulverde models 21 kWh per kW (1.4%) below it. Bulverde lies 0.31 degrees of latitude north of San Antonio, and the sun stands higher in the sky the further south you go, which matches its lower modeled output. The weather station for Bulverde is 1.0 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, 88 km northeast, where the same model gives 1,483 kWh per kW, so Bulverde runs 1 above that figure. Against the Texas median place month by month, Bulverde runs at least 2% higher in March, July, October. It runs at least 2% lower in January, February, April, May, June, September, November, December.

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 1,484 kWh would come to $184 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Bulverde 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 $229 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.
