Against Dallas
The nearest of the six largest modeled places is Dallas, 46 km to the northwest, at 1,500 kWh per kW. Post Oak Bend models 20 kWh per kW (1.3%) below it. At 0.16 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 (2.9 km and 2.4 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Fort Worth, 98 km west, where the same model gives 1,535 kWh per kW, so Post Oak Bend runs 55 below that figure. Against the Texas median place month by month, Post Oak Bend runs at least 2% higher in July. It runs at least 2% lower in January, February, March, April, September, October, November, December.

Size the array, see the kWh.
Scale the Post Oak Bend 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.

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.
