Against Dallas
The nearest of the six largest modeled places is Dallas, 37 km to the southwest, at 1,500 kWh per kW. Mobile City models 24 kWh per kW (1.6%) above it. At 0.13 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 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 Fort Worth, 89 km west, where the same model gives 1,535 kWh per kW, so Mobile City runs 11 below that figure. Against the Texas median place month by month, Mobile City runs at least 2% higher in April, June, October, December. It runs at least 2% lower in February, September, November.

Electricity prices nearby
EIA lists Oncor Electric Delivery in this county. Where Mobile City is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Mobile City 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 1,524 kWh at $233 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.
Scale the Mobile City 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 $235 per kW a year as plain multiplication.

Getting a measured number
A model cannot see your roof. Installers measure pitch, shade and the electrical panel on site. Quote marketplaces such as EnergySage, SolarReviews and WattBuy collect bids from local installers. Rate & Roof does not rank installers.

The sliders above price the energy at one rate. The payback calculator adds the system cost and your buyback plan type, and shows every assumption. It is an estimate, not advice.
