Sun on a roof in Texarkana.
The PVWatts model puts a generic roof array in Texarkana at 1,425 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 Texarkana climbs and falls, and the modeled output follows it.

How Texarkana comparesderived from the figures above
Where Texarkana sits.
Texarkana ranks 147th of 157 Texas places modeled here, at the 7th percentile. Its 1,425 kWh per kW is below the Texas median of 1,518. The strongest months are June, August, May and the weakest are December, February, November; output peaks in June and bottoms out in December. In all, 29.7% of the year arrives in June, July and August, more than the 29.4% of the median place.

Against Dallas
The nearest of the six largest modeled places is Dallas, 260 km to the west, at 1,500 kWh per kW. Texarkana models 75 kWh per kW (5.0%) below it. Texarkana lies 0.66 degrees of latitude north of Dallas, and the sun stands higher in the sky the further south you go, which matches its lower modeled output. The weather station for Texarkana is 0.9 km from the modeled point, against 2.4 km for Dallas, so part of the gap can come from which station's typical year was used.
The second-nearest large place is Fort Worth, 313 km west, where the same model gives 1,535 kWh per kW, so Texarkana runs 110 below that figure. It runs at least 2% lower in February, April, July, August, September, October, November, December.

Providers listed in the county
- Southwestern Electric Power Co: 12.6¢ per kWh, a bundled average, 157,119 residential customers across 25 counties.
- Bowie-Cass Electric Coop, Inc: 13.35¢ per kWh, a bundled average, 34,727 residential customers across 6 counties.
- Southwest Arkansas E C C: 13.29¢ per kWh, a bundled average, 1,094 residential customers across 2 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 1,425 kWh would come to $180 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Texarkana 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 $220 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.
