Against Dallas
The nearest of the six largest modeled places is Dallas, 159 km to the northwest, at 1,500 kWh per kW. Whitehouse models 42 kWh per kW (2.8%) below it. Whitehouse lies 0.57 degrees of latitude south of Dallas, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The weather station for Whitehouse is 1.1 km from the modeled point, against 2.4 km for Dallas, so part of the gap can come from which station's typical year was used.
The second-nearest large place is Fort Worth, 209 km west, where the same model gives 1,535 kWh per kW, so Whitehouse runs 77 below that figure. Against the Texas median place month by month, Whitehouse runs at least 2% higher in April. It runs at least 2% lower in January, February, March, June, July, August, September, October, November, December.
Electricity in Smith CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery in this county. Where Whitehouse is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Whitehouse 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 1,458 kWh at $223 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 Whitehouse 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 $225 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.
