Sun on a roof in Carbon.
The PVWatts model puts a generic roof array in Carbon at 1,590 kWh a year for each kW of panels, using typical-year weather from a station 2.4 km away. A modeled estimate for a standard setup, not a measurement of any roof.
A year on one roof.
Scroll from January to December: the noon sun over Carbon climbs and falls, and the modeled output follows it.

How Carbon comparesderived from the figures above
Where Carbon sits.
Carbon ranks 242nd of 1220 Texas places modeled here, at the 80th percentile. Its 1,590 kWh per kW is above the Texas median of 1,515. The strongest months are July, April, June and the weakest are December, February, January; output peaks in July and bottoms out in December. In all, 28.6% of the year arrives in June, July and August, less than the 29.3% of the median place.
Closest modeled neighbors
- Eastland, 14 km north: 1,594 kWh per kW, 4 more than Carbon.

- Rising Star, 23 km southwest: 1,609 kWh per kW, 19 more than Carbon.
- Ranger, 26 km northeast: 1,570 kWh per kW, 20 less than Carbon.
- De Leon, 33 km southeast: 1,597 kWh per kW, 7 more than Carbon.
- Cross Plains, 36 km southwest: 1,602 kWh per kW, 12 more than Carbon.
- Putnam, 37 km west: 1,616 kWh per kW, 26 more than Carbon.

Against Fort Worth
The nearest of the six largest modeled places is Fort Worth, 150 km to the northeast, at 1,535 kWh per kW. Carbon models 55 kWh per kW (3.6%) above it. Carbon lies 0.51 degrees of latitude south of Fort Worth, and the sun stands higher in the sky the further south you go, which matches its higher modeled output. The two weather stations sit a similar distance from their points (2.4 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, 202 km east, where the same model gives 1,500 kWh per kW, so Carbon runs 90 above that figure. Against the Texas median place month by month, Carbon runs at least 2% higher in January, February, March, April, June, September, November, December.
Electricity in Eastland CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery, AEP Texas North, and Texas-New Mexico Power in this county. Where Carbon is on Oncor Electric Delivery, AEP Texas North, and Texas-New Mexico Power's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Carbon 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 1,590 kWh at $244 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.
- Taylor Electric Coop Inc: 16.14¢ per kWh, a bundled average, 19,215 residential customers across 11 counties.
- Comanche County Elec Coop Assn: 15.65¢ per kWh, a bundled average, 7,487 residential customers across 7 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 Carbon. 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 Carbon 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 $245 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.
