Against San Antonio

The nearest of the six largest modeled places is San Antonio, 115 km to the north, at 1,505 kWh per kW. Three Rivers models 28 kWh per kW (1.9%) above it. Three Rivers lies 0.99 degrees of latitude south of San Antonio, and the sun stands higher in the sky the further south you go, which matches its higher modeled output. The two weather stations sit a similar distance from their points (2.2 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, 208 km north, where the same model gives 1,483 kWh per kW, so Three Rivers runs 50 above that figure. Against the Texas median place month by month, Three Rivers runs at least 2% higher in February, March, October, November, December. It runs at least 2% lower in January, June, September.

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 1,533 kWh at $235 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.

Scale the Three Rivers 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 $236 per kW a year as plain multiplication.
