Sun on a roof in Flatonia.

The PVWatts model puts a generic roof array in Flatonia at 1,488 kWh a year for each kW of panels, using typical-year weather from a station 1.0 km away. A modeled estimate for a standard setup, not a measurement of any roof.

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

How Flatonia comparesderived from the figures above

Where Flatonia sits.

Flatonia ranks 835th of 1220 Texas places modeled here, at the 32nd percentile. Its 1,488 kWh per kW is below the Texas median of 1,515. The strongest months are July, August, May and the weakest are December, January, February; output peaks in July and bottoms out in December. In all, 29.2% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against Austin

The nearest of the six largest modeled places is Austin, 92 km to the northwest, at 1,483 kWh per kW. Flatonia models 5 kWh per kW (0.3%) 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 San Antonio, 139 km west, where the same model gives 1,505 kWh per kW, so Flatonia runs 17 below that figure. Against the Texas median place month by month, Flatonia runs at least 2% higher in May, November. It runs at least 2% lower in January, March, June, July, September, December.

Providers listed in the county

They are the largest bundled providers 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. Priced at the first provider's average, the modeled 1,488 kWh would come to $172 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.

Scale the Flatonia 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 $229 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.

  • 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.
