Sun on a roof in Graham.
The PVWatts model puts a generic roof array in Graham at 1,555 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 Fort Worth
The nearest of the six largest modeled places is Fort Worth, 120 km to the east, at 1,535 kWh per kW. Graham models 20 kWh per kW (1.3%) above it. Graham lies 0.32 degrees of latitude north of Fort Worth, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The two weather stations sit a similar distance from their points (1.1 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Dallas, 172 km east, where the same model gives 1,500 kWh per kW, so Graham runs 55 above that figure. Against the Texas median place month by month, Graham runs at least 2% higher in January, February, March, April, July, December. It runs at least 2% lower in September, November.
Electricity in Young CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery and Texas-New Mexico Power in this county. Where Graham 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 Graham 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 1,555 kWh at $238 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- 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 Graham. 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 Graham 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 $239 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.
