Against San Antonio

At 0.29 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The weather station for Spofford is 1.0 km from the modeled point, against 2.2 km for San Antonio, so part of the gap can come from which station's typical year was used.

The second-nearest large place is Austin, 286 km northeast, where the same model gives 1,483 kWh per kW, so Spofford runs 67 above that figure. Against the Texas median place month by month, Spofford runs at least 2% higher in January, February, March, December. It runs at least 2% lower in June.

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 1,550 kWh at $237 per kW a year, plain multiplication and not a savings estimate or an offer.

Scale the Spofford 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 $239 per kW a year as plain multiplication.
