Sun on a roof in Commerce.

The PVWatts model puts a generic roof array in Commerce at 1,492 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.

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

How Commerce comparesderived from the figures above

Where Commerce sits.

Commerce ranks 807th of 1220 Texas places modeled here, at the 34th percentile. Its 1,492 kWh per kW is below the Texas median of 1,515. The strongest months are July, May, August and the weakest are December, February, January; output peaks in July and bottoms out in December. In all, 29.8% 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, 95 km to the southwest, at 1,500 kWh per kW. Commerce models 8 kWh per kW (0.5%) below 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 Dallas's.

The second-nearest large place is Fort Worth, 145 km west, where the same model gives 1,535 kWh per kW, so Commerce runs 43 below that figure. Against the Texas median place month by month, Commerce runs at least 2% higher in May. It runs at least 2% lower in February, March, August, September, October.

Electricity in Hunt CountyEIA-861

Electricity prices nearby

EIA lists Oncor Electric Delivery and Texas-New Mexico Power in this county. Where Commerce 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 Commerce 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 1,492 kWh at $229 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 Commerce. 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 Commerce 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 $230 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.
