Sun on a roof in Big Sandy.

The PVWatts model puts a generic roof array in Big Sandy at 1,434 kWh a year for each kW of panels, using typical-year weather from a station 2.4 km away. A modeled estimate for a standard setup, not a measurement of any roof.

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

How Big Sandy comparesderived from the figures above

Where Big Sandy sits.

Big Sandy ranks 1084th of 1220 Texas places modeled here, at the 11th percentile. Its 1,434 kWh per kW is below the Texas median of 1,515. The strongest months are July, May, August and the weakest are February, January, December; output peaks in July and bottoms out in February. In all, 30.3% 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, 157 km to the west, at 1,500 kWh per kW. Big Sandy models 66 kWh per kW (4.4%) below it. At 0.2 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The two weather stations sit a similar distance from their points (2.4 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, 211 km west, where the same model gives 1,535 kWh per kW, so Big Sandy runs 101 below that figure. It runs at least 2% lower in January, February, March, April, July, August, September, October, November, 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 1,434 kWh would come to $181 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.

Scale the Big Sandy 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.

8,604 kWh/yr

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.
