Against San Antonio
The nearest of the six largest modeled places is San Antonio, 33 km to the north, at 1,505 kWh per kW. Sandy Oaks models 12 kWh per kW (0.8%) below it. The two figures are within 1 percent, which is about the size of the difference you get from two neighboring weather stations alone, so this page's result is effectively the same as San Antonio's.
The second-nearest large place is Austin, 140 km northeast, where the same model gives 1,483 kWh per kW, so Sandy Oaks runs 10 above that figure. Against the Texas median place month by month, Sandy Oaks runs at least 2% higher in January, March, December. It runs at least 2% lower in February, April, May, September, November.

Priced at the first provider's average, the modeled 1,493 kWh would come to $185 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Sandy Oaks 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 $230 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.
