Sun on a roof in Happy.
The PVWatts model puts a generic roof array in Happy at 1,721 kWh a year for each kW of panels, using typical-year weather from a station 1.1 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Against Fort Worth
The nearest of the six largest modeled places is Fort Worth, 470 km to the southeast, at 1,535 kWh per kW. Happy models 186 kWh per kW (12.1%) above it. Happy lies 1.96 degrees of latitude north of Fort Worth, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The two weather stations sit a similar distance from their points (1.1 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 Dallas, 518 km southeast, where the same model gives 1,500 kWh per kW, so Happy runs 221 above that figure. Against the Texas median place month by month, Happy runs at least 2% higher in January, February, March, April, May, June, July, August, September, October, November, December.

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 1,721 kWh would come to $240 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Happy 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 $265 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.
