Sun on a roof in Vega.
The PVWatts model puts a generic roof array in Vega at 1,745 kWh a year for each kW of panels, using typical-year weather from a station 0.9 km away. A modeled estimate for a standard setup, not a measurement of any roof.
A year on one roof.
Scroll from January to December: the noon sun over Vega climbs and falls, and the modeled output follows it.

How Vega comparesderived from the figures above
Where Vega sits.
Vega ranks 57th of 1220 Texas places modeled here, at the 95th percentile. Its 1,745 kWh per kW is above the Texas median of 1,515. The strongest months are July, May, June and the weakest are December, February, November; output peaks in July and bottoms out in December. In all, 28.4% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against El Paso
The nearest of the six largest modeled places is El Paso, 529 km to the southwest, at 1,835 kWh per kW. Vega models 90 kWh per kW (4.9%) below it. Vega lies 3.4 degrees of latitude north of El Paso, and the sun stands higher in the sky the further south you go, which matches its lower modeled output. The two weather stations sit a similar distance from their points (0.9 km and 0.9 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, 543 km southeast, where the same model gives 1,535 kWh per kW, so Vega runs 210 above that figure. Against the Texas median place month by month, Vega runs at least 2% higher in January, February, March, April, May, June, July, August, September, October, November, December.

Providers listed in the county
- Southwestern Public Service Co: 13.94¢ per kWh, a bundled average, 223,685 residential customers across 45 counties.
- Deaf Smith Electric Coop, Inc: 8.57¢ per kWh, a bundled average, 2,993 residential customers across 4 counties.
- Rita Blanca Electric Coop, Inc: 8.41¢ per kWh, a bundled average, 1,166 residential customers across 8 counties.
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 1,745 kWh would come to $243 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Vega 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 $269 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.
