Sun on a roof in Earth.
The PVWatts model puts a generic roof array in Earth at 1,724 kWh a year for each kW of panels, using typical-year weather from a station 2.4 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 Earth climbs and falls, and the modeled output follows it.

How Earth comparesderived from the figures above
Where Earth sits.
Earth ranks 83rd of 1220 Texas places modeled here, at the 93rd percentile. Its 1,724 kWh per kW is above the Texas median of 1,515. The strongest months are May, June, July and the weakest are December, November, February; output peaks in May and bottoms out in December. In all, 28.5% 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, 459 km to the southwest, at 1,835 kWh per kW. Earth models 111 kWh per kW (6.0%) below it. Earth lies 2.38 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 weather station for Earth is 2.4 km from the modeled point, against 0.9 km for El Paso, so part of the gap can come from which station's typical year was used.
The second-nearest large place is Fort Worth, 496 km east, where the same model gives 1,535 kWh per kW, so Earth runs 189 above that figure. Against the Texas median place month by month, Earth 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.
- South Plains Electric Coop Inc: 11.02¢ per kWh, a bundled average, 58,726 residential customers across 18 counties.
- Bailey County Elec Coop Assn: 9.82¢ per kWh, a bundled average, 3,461 residential customers across 5 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 1,724 kWh would come to $240 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Earth 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.
