Against Houston
The nearest of the six largest modeled places is Houston, 42 km to the northeast, at 1,422 kWh per kW. Thompsons models 37 kWh per kW (2.6%) above it. Thompsons lies 0.31 degrees of latitude south of Houston, and the sun stands higher in the sky the further south you go, which matches its higher modeled output. 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, 223 km northwest, where the same model gives 1,483 kWh per kW, so Thompsons runs 24 below that figure. Against the Texas median place month by month, Thompsons runs at least 2% higher in November. It runs at least 2% lower in February, April, June, July, August, September, December.

Electricity prices nearby
EIA lists CenterPoint Energy Houston Electric in this county. Where Thompsons 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 1,459 kWh at $224 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.
Scale the Thompsons 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.
