Sun on a roof in Ingram.
The PVWatts model puts a generic roof array in Ingram at 1,541 kWh a year for each kW of panels, using typical-year weather from a station 2.2 km away. A modeled estimate for a standard setup, not a measurement of any roof.
A year on one roof.
Scroll from January to December: the noon sun over Ingram climbs and falls, and the modeled output follows it.

How Ingram comparesderived from the figures above
Where Ingram sits.
Ingram ranks 406th of 1220 Texas places modeled here, at the 67th percentile. Its 1,541 kWh per kW is above the Texas median of 1,515. The strongest months are July, August, June and the weakest are December, November, February; output peaks in July and bottoms out in December. In all, 29.3% of the year arrives in June, July and August, about the same than the 29.3% of the median place.

Against San Antonio
The nearest of the six largest modeled places is San Antonio, 98 km to the southeast, at 1,505 kWh per kW. Ingram models 36 kWh per kW (2.4%) above it. Ingram lies 0.62 degrees of latitude north of San Antonio, 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 (2.2 km and 2.2 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Austin, 145 km east, where the same model gives 1,483 kWh per kW, so Ingram runs 58 above that figure. Against the Texas median place month by month, Ingram runs at least 2% higher in January, February, March, August, September, October. It runs at least 2% lower in November, December.

Providers listed in the county
- Pedernales Electric Coop, Inc: 12.75¢ per kWh, a bundled average, 420,753 residential customers across 24 counties.
- Central Texas Elec Coop, Inc: 12.17¢ per kWh, a bundled average, 40,305 residential customers across 11 counties.
- Bandera Electric Coop, Inc: 12.77¢ per kWh, a bundled average, 35,906 residential customers across 7 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 1,541 kWh would come to $196 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Ingram 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 $237 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.
