Against Houston

The nearest of the six largest modeled places is Houston, 88 km to the north, at 1,422 kWh per kW. Sweeny models 31 kWh per kW (2.2%) above it. Sweeny lies 0.74 degrees of latitude south of Houston, and the sun stands higher in the sky the further south you go, which matches its higher modeled output. The weather station for Sweeny is 0.0 km from the modeled point, against 2.4 km for Houston, so part of the gap can come from which station's typical year was used.

The second-nearest large place is Austin, 242 km northwest, where the same model gives 1,483 kWh per kW, so Sweeny runs 30 below that figure. Against the Texas median place month by month, Sweeny runs at least 2% higher in November. It runs at least 2% lower in January, February, March, April, June, July, August, December.

Scale the Sweeny 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 $224 per kW a year as plain multiplication.
