Against Austin

The nearest of the six largest modeled places is Austin, 60 km to the south, at 1,483 kWh per kW. Florence models 33 kWh per kW (2.2%) above it. Florence lies 0.54 degrees of latitude north of Austin, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The two weather stations sit a similar distance from their points (1.5 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.

The second-nearest large place is San Antonio, 169 km southwest, where the same model gives 1,505 kWh per kW, so Florence runs 11 above that figure. Against the Texas median place month by month, Florence runs at least 2% higher in January, February, March. It runs at least 2% lower in April, June, July.

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 1,516 kWh at $232 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.

Scale the Florence 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 $233 per kW a year as plain multiplication.
