Against Austin
The nearest of the six largest modeled places is Austin, 24 km to the south, at 1,483 kWh per kW. Cedar Park models 38 kWh per kW (2.6%) above it. At 0.21 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The two weather stations sit a similar distance from their points (2.2 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is San Antonio, 135 km southwest, where the same model gives 1,505 kWh per kW, so Cedar Park runs 16 above that figure. Against the Texas median place month by month, Cedar Park runs at least 2% higher in January, April. It runs at least 2% lower in February, March, November.

Size the array, see the kWh.
Scale the Cedar Park 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 $235 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.
