Against Houston

The nearest of the six largest modeled places is Houston, 67 km to the east, at 1,422 kWh per kW. Wallis models 55 kWh per kW (3.9%) above it. At 0.16 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The two weather stations sit a similar distance from their points (2.2 km and 2.4 km), so station distance does little to explain the gap, and the weather record does the rest.

The second-nearest large place is Austin, 179 km northwest, where the same model gives 1,483 kWh per kW, so Wallis runs 6 below that figure. Against the Texas median place month by month, Wallis runs at least 2% higher in October. It runs at least 2% lower in January, April, June, July, August, December.

Electricity prices nearby

EIA lists CenterPoint Energy Houston Electric in this county. Where Wallis is on CenterPoint Energy Houston Electric's lines, homes buy energy from a retail electricity provider and the price depends on the plan.

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 1,477 kWh at $226 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.

Scale the Wallis 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.
