Sun on a roof in Cibolo.
The PVWatts model puts a generic roof array in Cibolo at 1,496 kWh a year for each kW of panels, using typical-year weather from a station 0.0 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, 32 km to the southwest, at 1,505 kWh per kW. Cibolo models 9 kWh per kW (0.6%) 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, 93 km northeast, where the same model gives 1,483 kWh per kW, so Cibolo runs 13 above that figure. Against the Texas median place month by month, Cibolo runs at least 2% higher in March, November. It runs at least 2% lower in February, April, May, June, September.

Size the array, see the kWh.
Scale the Cibolo 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 $231 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.

The sliders above price the energy at one rate. The payback calculator adds the system cost and your buyback plan type, and shows every assumption. It is an estimate, not advice.
