Against Houston

The nearest of the six largest modeled places is Houston, 57 km to the east, at 1,422 kWh per kW. Pattison models 55 kWh per kW (3.9%) above it. At 0.03 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The weather station for Pattison is 1.1 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, 179 km west, where the same model gives 1,483 kWh per kW, so Pattison runs 6 below that figure. Against the Texas median place month by month, Pattison runs at least 2% higher in November. It runs at least 2% lower in January, February, March, July, August, September, October, December.

Scale the Pattison 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 $227 per kW a year as plain multiplication.
