Sun on a roof in Carrizo Springs.
The PVWatts model puts a generic roof array in Carrizo Springs at 1,575 kWh a year for each kW of panels, using typical-year weather from a station 0.0 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, 166 km to the northeast, at 1,505 kWh per kW. Carrizo Springs models 70 kWh per kW (4.7%) above it. Carrizo Springs lies 0.93 degrees of latitude south of San Antonio, and the sun stands higher in the sky the further south you go, which matches its higher modeled output. The weather station for Carrizo Springs is 0.0 km from the modeled point, against 2.2 km for San Antonio, so part of the gap can come from which station's typical year was used.
The second-nearest large place is Austin, 284 km northeast, where the same model gives 1,483 kWh per kW, so Carrizo Springs runs 92 above that figure. Against the Texas median place month by month, Carrizo Springs runs at least 2% higher in January, February, March, April, August, October, December.

Electricity prices nearby
EIA lists AEP Texas Central in this county. Where Carrizo Springs is on AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Carrizo Springs may instead be served by a co-op or utility listed below, which sets its own rates; check your bill. For scale only, the median 2025 average price across the 60 Texas retail providers on this site is 15.32¢ per kWh, which would put the modeled 1,575 kWh at $241 per kW a year, plain multiplication and not a savings estimate or an offer.

- Medina Electric Coop, Inc: 12.54¢ per kWh, a bundled average, 30,778 residential customers across 17 counties.
- Rio Grande Electric Coop, Inc: 18.29¢ per kWh, a bundled average, 9,371 residential customers across 18 counties.

These utilities serve other parts of the county, which can include parts of Carrizo Springs. They are the largest bundled providers, and the largest delivery-only one, 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 Carrizo Springs 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 $243 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.

Payback, buyback.
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.
