Sun on a roof in Hemphill.
The PVWatts model puts a generic roof array in Hemphill at 1,372 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.

How Hemphill comparesderived from the figures above
Where Hemphill sits.
Hemphill ranks 1190th of 1220 Texas places modeled here, at the 3rd percentile. Its 1,372 kWh per kW is below the Texas median of 1,515. The strongest months are May, July, June and the weakest are December, February, January; output peaks in May and bottoms out in December. In all, 28.7% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against Houston
The nearest of the six largest modeled places is Houston, 227 km to the southwest, at 1,422 kWh per kW. Hemphill models 50 kWh per kW (3.5%) below it. Hemphill lies 1.55 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 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 Dallas, 319 km northwest, where the same model gives 1,500 kWh per kW, so Hemphill runs 128 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
- Deep East Texas Elec Coop Inc: 14.05¢ per kWh, a bundled average, 40,593 residential customers across 8 counties.
- Jasper-Newton Elec Coop, Inc: 14.1¢ per kWh, a bundled average, 21,316 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 1,372 kWh would come to $193 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Hemphill 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 $211 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.
