Sun on a roof in Kerrville.
The PVWatts model puts a generic roof array in Kerrville at 1,552 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.

Against San Antonio
The nearest of the six largest modeled places is San Antonio, 87 km to the southeast, at 1,505 kWh per kW. Kerrville models 47 kWh per kW (3.1%) above it. Kerrville lies 0.58 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 (1.5 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, 136 km east, where the same model gives 1,483 kWh per kW, so Kerrville runs 69 above that figure. Against the Texas median place month by month, Kerrville runs at least 2% higher in February, March, April, August, October, November, December. It runs at least 2% lower in September.
Electricity in Kerr CountyEIA-861
Electricity prices nearby
Kerrville is served by its own municipal utility, Kerrville Public Utility Board. Municipal utilities in Texas generally sit outside retail choice, so homes in the city buy from the city utility. Its 2025 residential average was 9.42¢ per kWh, which would put the modeled 1,552 kWh at $146 per kW a year, plain multiplication and not a savings estimate.
Other 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.
These serve areas outside the city utility. 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.

Size the array, see the kWh.
Scale the Kerrville 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 $240 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.
