Against San Antonio
The nearest of the six largest modeled places is San Antonio, 390 km to the north, at 1,505 kWh per kW. Los Fresnos models 9 kWh per kW (0.6%) above 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 Houston, 462 km northeast, where the same model gives 1,422 kWh per kW, so Los Fresnos runs 92 above that figure. Against the Texas median place month by month, Los Fresnos runs at least 2% higher in February, April. It runs at least 2% lower in June, September, November.

Electricity prices nearby
EIA lists AEP Texas Central in this county. Where Los Fresnos is on AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Los Fresnos 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 1,514 kWh at $232 per kW a year, plain multiplication and not a savings estimate or an offer.

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 Los Fresnos 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 $233 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.
