Sun on a roof in Bandera.
The PVWatts model puts a generic roof array in Bandera at 1,478 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.

How Bandera comparesderived from the figures above
Where Bandera sits.
Bandera ranks 912th of 1220 Texas places modeled here, at the 25th percentile. Its 1,478 kWh per kW is below the Texas median of 1,515. The strongest months are August, July, June and the weakest are December, November, January; output peaks in August and bottoms out in December. In all, 29.9% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against San Antonio
The nearest of the six largest modeled places is San Antonio, 61 km to the southeast, at 1,505 kWh per kW. Bandera models 27 kWh per kW (1.8%) below it. At 0.27 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The weather station for Bandera 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, 142 km northeast, where the same model gives 1,483 kWh per kW, so Bandera runs 5 below that figure. Against the Texas median place month by month, Bandera runs at least 2% higher in February. It runs at least 2% lower in May, June, September, November, December.

Providers listed in the county
- City of San Antonio: 12.4¢ per kWh, a bundled average, 888,946 residential customers across 8 counties.
- Bandera Electric Coop, Inc: 12.77¢ per kWh, a bundled average, 35,906 residential customers across 7 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 1,478 kWh would come to $183 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Bandera 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 $228 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.
