Sun on a roof in Groom.
The PVWatts model puts a generic roof array in Groom at 1,702 kWh a year for each kW of panels, using typical-year weather from a station 0.9 km away. A modeled estimate for a standard setup, not a measurement of any roof.

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

How Groom comparesderived from the figures above
Where Groom sits.
Groom ranks 111th of 1220 Texas places modeled here, at the 91st percentile. Its 1,702 kWh per kW is above the Texas median of 1,515. The strongest months are May, June, July and the weakest are December, February, November; output peaks in May and bottoms out in December. In all, 28.4% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against Fort Worth
The nearest of the six largest modeled places is Fort Worth, 439 km to the southeast, at 1,535 kWh per kW. Groom models 167 kWh per kW (10.9%) above it. Groom lies 2.43 degrees of latitude north of Fort Worth, 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 (0.9 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Dallas, 482 km southeast, where the same model gives 1,500 kWh per kW, so Groom runs 202 above that figure. Against the Texas median place month by month, Groom runs at least 2% higher in January, February, March, April, May, June, July, August, September, October, November, December.

Providers listed in the county
- Southwestern Public Service Co: 13.94¢ per kWh, a bundled average, 223,685 residential customers across 45 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 1,702 kWh would come to $237 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Groom 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 $262 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.

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.
