Against Fort Worth
The nearest of the six largest modeled places is Fort Worth, 37 km to the southwest, at 1,535 kWh per kW. Flower Mound models 11 kWh per kW (0.7%) above it. The two figures are within 1 percent, which is about the size of the difference you get from two neighboring weather stations alone, so this page's result is effectively the same as Fort Worth's.
The second-nearest large place is Dallas, 42 km southeast, where the same model gives 1,500 kWh per kW, so Flower Mound runs 46 above that figure. Against the Texas median place month by month, Flower Mound runs at least 2% higher in February, June, July, September, October, November. It runs at least 2% lower in January, December.

Electricity prices nearby
EIA lists Oncor Electric Delivery and Texas-New Mexico Power in this county. Where Flower Mound is on Oncor Electric Delivery and Texas-New Mexico Power's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Flower Mound 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 1,546 kWh at $237 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.
Scale the Flower Mound 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 15.47¢ per kWh. At that rate the modeled output is worth $239 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.

Payback, buyback.
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.
