Against Houston
The nearest of the six largest modeled places is Houston, 214 km to the south, at 1,422 kWh per kW. Nacogdoches models 21 kWh per kW (1.5%) below it. Nacogdoches lies 1.82 degrees of latitude north of Houston, and the sun stands higher in the sky the further south you go, which matches its lower modeled output. The weather station for Nacogdoches is 0.9 km from the modeled point, against 2.4 km for Houston, so part of the gap can come from which station's typical year was used.
The second-nearest large place is Dallas, 239 km northwest, where the same model gives 1,500 kWh per kW, so Nacogdoches runs 99 below that figure. It runs at least 2% lower in January, February, March, April, May, June, July, August, September, November, December.

Electricity prices nearby
EIA lists Oncor Electric Delivery in this county. Where Nacogdoches is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Nacogdoches 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 1,401 kWh at $215 per kW a year, plain multiplication and not a savings estimate or an offer.

Size the array, see the kWh.
Scale the Nacogdoches 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 $217 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.
