Sun on a roof in Gallatin.

The PVWatts model puts a generic roof array in Gallatin at 1,432 kWh a year for each kW of panels, using typical-year weather from a station 1.5 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Scroll from January to December: the noon sun over Gallatin climbs and falls, and the modeled output follows it.

How Gallatin comparesderived from the figures above

Where Gallatin sits.

Gallatin ranks 1093rd of 1220 Texas places modeled here, at the 10th percentile. Its 1,432 kWh per kW is below the Texas median of 1,515. The strongest months are July, August, May and the weakest are February, December, January; output peaks in July and bottoms out in February. In all, 29.6% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against Dallas

The nearest of the six largest modeled places is Dallas, 182 km to the northwest, at 1,500 kWh per kW. Gallatin models 68 kWh per kW (4.5%) below it. Gallatin lies 0.89 degrees of latitude south of Dallas, 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 (1.5 km and 2.4 km), so station distance does little to explain the gap, and the weather record does the rest.

The second-nearest large place is Fort Worth, 229 km northwest, where the same model gives 1,535 kWh per kW, so Gallatin runs 103 below that figure. It runs at least 2% lower in January, February, March, May, June, July, August, September, October, November, December.

Electricity in Cherokee CountyEIA-861

Electricity prices nearby

EIA lists Oncor Electric Delivery in this county. Where Gallatin is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Gallatin 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 1,432 kWh at $219 per kW a year, plain multiplication and not a savings estimate or an offer.

Also listed in the county

These utilities serve other parts of the county, which can include parts of Gallatin. 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 Gallatin 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.

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.

  • A model estimate for a generic system at this point, not a measurement and not a promise of output.
  • Shading, roof pitch, equipment and local rates will differ.
  • All prices on this site are in cents per kWh unless marked otherwise. Bills are US dollars per month.
