Against Fort Worth

The nearest of the six largest modeled places is Fort Worth, 62 km to the east, at 1,535 kWh per kW. Cool models 20 kWh per kW (1.3%) above it. At 0.02 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 (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 Dallas, 116 km east, where the same model gives 1,500 kWh per kW, so Cool runs 55 above that figure. Against the Texas median place month by month, Cool runs at least 2% higher in January, February, March, April, May, June, September, December. It runs at least 2% lower in July, August.

Electricity prices nearby

EIA lists Oncor Electric Delivery in this county. Where Cool is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Cool may instead be served by a co-op or utility listed below, which sets its own rates; check your bill. 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 1,555 kWh at $238 per kW a year, plain multiplication and not a savings estimate or an offer.

A county can list several, and which one serves a street depends on the address, so check your bill.

Size the array, see the kWh.

Scale the Cool 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 $239 per kW a year as plain multiplication.
