Against San Antonio

The nearest of the six largest modeled places is San Antonio, 230 km to the northwest, at 1,505 kWh per kW. Port Aransas models 39 kWh per kW (2.6%) above it. Port Aransas lies 1.64 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 (1.5 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 Houston, 275 km northeast, where the same model gives 1,422 kWh per kW, so Port Aransas runs 122 above that figure. Against the Texas median place month by month, Port Aransas runs at least 2% higher in March, April, May, August, October, November. It runs at least 2% lower in January, February, December.

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 1,544 kWh at $237 per kW a year, plain multiplication and not a savings estimate or an offer.

Scale the Port Aransas 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.
