Sun on a roof in Roanoke.
The PVWatts model puts a generic roof array in Roanoke at 1,546 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.

Against Fort Worth
The nearest of the six largest modeled places is Fort Worth, 28 km to the southwest, at 1,535 kWh per kW. Roanoke models 11 kWh per kW (0.7%) above it. The two figures are within 1 percent, which is about the size of the difference you get from two neighboring weather stations alone, so this page's result is effectively the same as Fort Worth's.
The second-nearest large place is Dallas, 49 km southeast, where the same model gives 1,500 kWh per kW, so Roanoke runs 46 above that figure. Against the Texas median place month by month, Roanoke runs at least 2% higher in January, February, June, July, August, September, November, December. It runs at least 2% lower in October.
Electricity in Tarrant County, Denton CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery and Texas-New Mexico Power in this county. Where Roanoke 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 Roanoke 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 1,546 kWh at $237 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Denton County Elec Coop, Inc: 13.18¢ per kWh, a bundled average, 310,805 residential customers across 6 counties.
- Tri-County Electric Coop, Inc (TX): 15.07¢ per kWh, a bundled average, 117,857 residential customers across 16 counties.
- United Electric Coop Service Inc: 13.91¢ per kWh, a bundled average, 91,268 residential customers across 14 counties.
- Oncor Electric Delivery Company LLC: 5.64¢ per kWh, delivery charges only, before the retail energy price, 3,545,814 residential customers across 99 counties.
These utilities serve other parts of the county, which can include parts of Roanoke. 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 Roanoke 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 $238 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.
