Sun on a roof in Annona.

Against Dallas
The nearest of the six largest modeled places is Dallas, 194 km to the southwest, at 1,500 kWh per kW. Annona models 63 kWh per kW (4.2%) below it. Annona lies 0.79 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 Annona is 1.4 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, 244 km west, where the same model gives 1,535 kWh per kW, so Annona runs 98 below that figure. It runs at least 2% lower in January, February, April, June, August, September, October, November, December.
Electricity in Red River CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery and Texas-New Mexico Power in this county. Where Annona 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 Annona 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 1,437 kWh at $220 per kW a year, plain multiplication and not a savings estimate or an offer.
Also 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.

These utilities serve other parts of the county, which can include parts of Annona. 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 Annona 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 $221 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.

Payback, buyback.
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.
