Sun on a roof in Tenaha.
The PVWatts model puts a generic roof array in Tenaha at 1,397 kWh a year for each kW of panels, using typical-year weather from a station 1.5 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Scroll from January to December: the noon sun over Tenaha climbs and falls, and the modeled output follows it.

How Tenaha comparesderived from the figures above
Where Tenaha sits.
Tenaha ranks 1158th of 1220 Texas places modeled here, at the 5th percentile. Its 1,397 kWh per kW is below the Texas median of 1,515. The strongest months are July, August, May and the weakest are December, February, November; output peaks in July and bottoms out in December. In all, 29.6% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against Dallas
The nearest of the six largest modeled places is Dallas, 255 km to the west, at 1,500 kWh per kW. Tenaha models 103 kWh per kW (6.9%) below it. Tenaha lies 0.85 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 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 Houston, 263 km southwest, where the same model gives 1,422 kWh per kW, so Tenaha runs 25 below that figure. It runs at least 2% lower in January, February, March, April, May, June, July, August, September, October, November, December.

Providers listed in the county
- Southwestern Electric Power Co: 12.6¢ per kWh, a bundled average, 157,119 residential customers across 25 counties.
- Deep East Texas Elec Coop Inc: 14.05¢ per kWh, a bundled average, 40,593 residential customers across 8 counties.
- Rusk County Electric Coop, Inc: 13.3¢ per kWh, a bundled average, 18,253 residential customers across 5 counties.
They are the largest bundled providers whose EIA service territory lists the county. A county can list several, and which one serves a street depends on the address, so check your bill. Priced at the first provider's average, the modeled 1,397 kWh would come to $176 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Tenaha 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 $215 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.
