Sun on a roof in Olmos Park.

The PVWatts model puts a generic roof array in Olmos Park at 1,522 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 Olmos Park climbs and falls, and the modeled output follows it.

How Olmos Park comparesderived from the figures above

Where Olmos Park sits.

Olmos Park ranks 536th of 1220 Texas places modeled here, at the 56th percentile. Its 1,522 kWh per kW is above the Texas median of 1,515. The strongest months are August, July, June and the weakest are December, January, February; output peaks in August and bottoms out in December. In all, 29.4% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against San Antonio

The nearest of the six largest modeled places is San Antonio, 3 km to the west, at 1,505 kWh per kW. Olmos Park models 17 kWh per kW (1.1%) above it. At 0.01 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 2.2 km), so station distance does little to explain the gap, and the weather record does the rest.

The second-nearest large place is Austin, 117 km northeast, where the same model gives 1,483 kWh per kW, so Olmos Park runs 39 above that figure. Against the Texas median place month by month, Olmos Park runs at least 2% higher in February, August, October, November, December. It runs at least 2% lower in March, April, May, June, September.

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 1,522 kWh would come to $189 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.

Scale the Olmos Park 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 $234 per kW a year as plain multiplication.

9,132 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.
  • All prices on this site are in cents per kWh unless marked otherwise. Bills are US dollars per month.
