Sun on a roof in Lake City.
The PVWatts model puts a generic roof array in Lake City at 1,499 kWh a year for each kW of panels, using typical-year weather from a station 2.3 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 north, at 1,505 kWh per kW. Lake City models 6 kWh per kW (0.4%) below it. The two figures are within 1 percent, which is about the size of the difference you get from two neighboring weather stations alone, so this page's result is effectively the same as San Antonio's.
The second-nearest large place is Austin, 247 km north, where the same model gives 1,483 kWh per kW, so Lake City runs 16 above that figure. Against the Texas median place month by month, Lake City runs at least 2% higher in February, March. It runs at least 2% lower in January, April, July, August, October.
Electricity in San Patricio CountyEIA-861
Electricity prices nearby
EIA lists AEP Texas Central in this county. Where Lake City is on AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Lake City 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 1,499 kWh at $230 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- San Patricio Electric Coop Inc: 14.16¢ per kWh, a bundled average, 10,087 residential customers across 9 counties.
- AEP Texas Central Company: 5.91¢ per kWh, delivery charges only, before the retail energy price, 793,896 residential customers across 44 counties.
These utilities serve other parts of the county, which can include parts of Lake City. 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 Lake City 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 $231 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.
