Against Austin

The nearest of the six largest modeled places is Austin, 66 km to the southeast, at 1,483 kWh per kW. Horseshoe Bay models 63 kWh per kW (4.2%) above it. At 0.24 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 (1.1 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.

The second-nearest large place is San Antonio, 121 km south, where the same model gives 1,505 kWh per kW, so Horseshoe Bay runs 41 above that figure. Against the Texas median place month by month, Horseshoe Bay runs at least 2% higher in January, March, June, August, September, December. It runs at least 2% lower in November.

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 1,546 kWh at $237 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.

Scale the Horseshoe Bay 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 $238 per kW a year as plain multiplication.
