Against San Antonio

The nearest of the six largest modeled places is San Antonio, 371 km to the north, at 1,505 kWh per kW. Weslaco models 35 kWh per kW (2.3%) above it. Weslaco lies 3.3 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.
