Sun on a roof in De Kalb.
The PVWatts model puts a generic roof array in De Kalb at 1,455 kWh a year for each kW of panels, using typical-year weather from a station 2.2 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Where De Kalb sits.
De Kalb ranks 1003rd of 1220 Texas places modeled here, at the 18th percentile. Its 1,455 kWh per kW is below the Texas median of 1,515. The strongest months are June, July, May and the weakest are December, February, November; output peaks in June and bottoms out in December. In all, 30.4% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against Dallas
The nearest of the six largest modeled places is Dallas, 216 km to the west, at 1,500 kWh per kW. De Kalb models 45 kWh per kW (3.0%) below it. De Kalb lies 0.72 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 two weather stations sit a similar distance from their points (2.2 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, 267 km west, where the same model gives 1,535 kWh per kW, so De Kalb runs 80 below that figure. Against the Texas median place month by month, De Kalb runs at least 2% higher in June. It runs at least 2% lower in January, February, April, July, August, September, October, November, December.

- 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 1,455 kWh would come to $183 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the De Kalb 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 $224 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.
