Sun on a roof in DeSoto.
The PVWatts model puts a generic roof array in DeSoto at 1,525 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 Dallas
The nearest of the six largest modeled places is Dallas, 23 km to the north, at 1,500 kWh per kW. DeSoto models 25 kWh per kW (1.7%) above it. At 0.19 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The weather station for DeSoto is 1.1 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, 50 km northwest, where the same model gives 1,535 kWh per kW, so DeSoto runs 10 below that figure. Against the Texas median place month by month, DeSoto runs at least 2% higher in January, May, July, November. It runs at least 2% lower in June, October.

Electricity prices nearby
EIA lists Oncor Electric Delivery and Texas-New Mexico Power in this county. Where DeSoto is on Oncor Electric Delivery and Texas-New Mexico Power's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of DeSoto may instead be served by a co-op or utility listed below, which sets its own rates; check your bill. For scale only, the median 2025 average price across the 60 Texas retail providers on this site is 15.32¢ per kWh, which would put the modeled 1,525 kWh at $234 per kW a year, plain multiplication and not a savings estimate or an offer.

- Farmers Electric Coop, Inc: 11.95¢ per kWh, a bundled average, 88,221 residential customers across 12 counties.
- Trinity Valley Elec Coop Inc: 12.24¢ per kWh, a bundled average, 82,224 residential customers across 6 counties.

These utilities serve other parts of the county, which can include parts of DeSoto. They are the largest bundled providers, and the largest delivery-only one, 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.

Size the array, see the kWh.
Scale the DeSoto 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 $236 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.
