Sun on a roof in Laguna Vista.

Scroll from January to December: the noon sun over Laguna Vista climbs and falls, and the modeled output follows it.

Against San Antonio

The nearest of the six largest modeled places is San Antonio, 391 km to the north, at 1,505 kWh per kW. Laguna Vista models 64 kWh per kW (4.3%) above it. Laguna Vista lies 3.35 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 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 Houston, 450 km northeast, where the same model gives 1,422 kWh per kW, so Laguna Vista runs 147 above that figure. Against the Texas median place month by month, Laguna Vista runs at least 2% higher in February, March, May, August, September, October. It runs at least 2% lower in January.

Electricity in Cameron CountyEIA-861

Electricity prices nearby

EIA lists AEP Texas Central in this county. Where Laguna Vista is on AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Laguna Vista 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 1,569 kWh at $240 per kW a year, plain multiplication and not a savings estimate or an offer.

Also listed in the county

These utilities serve other parts of the county, which can include parts of Laguna Vista. 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 Laguna Vista 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 $242 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.
