Sun on a roof in Marquez.

The PVWatts model puts a generic roof array in Marquez 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.

A year on one roof.

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

How Marquez comparesderived from the figures above

Where Marquez sits.

Marquez 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, August, June 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 Austin

The nearest of the six largest modeled places is Austin, 177 km to the southwest, at 1,483 kWh per kW. Marquez models 9 kWh per kW (0.6%) 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 Austin's.

The second-nearest large place is Dallas, 179 km north, where the same model gives 1,500 kWh per kW, so Marquez runs 8 below that figure. It runs at least 2% lower in January, February, March, November, December.

Electricity in Leon CountyEIA-861

Electricity prices nearby

EIA lists Oncor Electric Delivery in this county. Where Marquez is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Marquez 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 Marquez. 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.

Modeled estimateruns in your browser

Size the array, see the kWh.

Scale the Marquez 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.

About - kWh in an average month. Priced at the chosen rate that energy comes to - a year, by multiplication only.

Assumes the same tilt, direction and equipment as the model below. Real output depends on the roof, shade, equipment and weather.

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.

  • 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.
