Sun on a roof in Ames.

The PVWatts model puts a generic roof array in Ames at 1,415 kWh a year for each kW of panels, using typical-year weather from a station 0.0 km away. A modeled estimate for a standard setup, not a measurement of any roof.

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

How Ames comparesderived from the figures above

Where Ames sits.

Ames ranks 1130th of 1220 Texas places modeled here, at the 7th percentile. Its 1,415 kWh per kW is below the Texas median of 1,515. The strongest months are July, May, June and the weakest are February, December, January; output peaks in July and bottoms out in February. In all, 28.5% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against Houston

The nearest of the six largest modeled places is Houston, 69 km to the southwest, at 1,422 kWh per kW. Ames models 7 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 Houston's.

The second-nearest large place is Austin, 291 km west, where the same model gives 1,483 kWh per kW, so Ames runs 68 below that figure. It runs at least 2% lower in February, March, April, May, June, July, August, September, October, December.

Electricity in Liberty CountyEIA-861

Electricity prices nearby

EIA lists CenterPoint Energy Houston Electric in this county. Where Ames is on CenterPoint Energy Houston Electric's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Ames 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 1,415 kWh at $217 per kW a year, plain multiplication and not a savings estimate or an offer.

Also listed in the county

  • Entergy Texas Inc.: 13.89¢ per kWh, a bundled average, 469,094 residential customers across 27 counties.
  • Sam Houston Electric Coop Inc: 14.18¢ per kWh, a bundled average, 88,424 residential customers across 10 counties.
  • CenterPoint Energy: 5.41¢ per kWh, delivery charges only, before the retail energy price, 2,529,039 residential customers across 12 counties.

These utilities serve other parts of the county, which can include parts of Ames. 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 Ames 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 $218 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.
