Against El Paso

The nearest of the six largest modeled places is El Paso, 398 km to the west, at 1,835 kWh per kW. Wellman models 75 kWh per kW (4.1%) below it. Wellman lies 1.2 degrees of latitude north of El Paso, and the sun stands higher in the sky the further south you go, which matches its lower modeled output. The two weather stations sit a similar distance from their points (0.9 km and 0.9 km), so station distance does little to explain the gap, and the weather record does the rest.

The second-nearest large place is Fort Worth, 475 km east, where the same model gives 1,535 kWh per kW, so Wellman runs 225 above that figure. Against the Texas median place month by month, Wellman runs at least 2% higher in January, February, March, April, May, June, July, August, September, October, November, December.

Size the array, see the kWh.

Scale the Wellman 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 $271 per kW a year as plain multiplication.
