Sun on a roof in Lyford.

The PVWatts model puts a generic roof array in Lyford at 1,545 kWh a year for each kW of panels, using typical-year weather from a station 1.0 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How Lyford comparesderived from the figures above

Where Lyford sits.

Lyford ranks 383rd of 1220 Texas places modeled here, at the 69th percentile. Its 1,545 kWh per kW is above the Texas median of 1,515. The strongest months are August, June, July and the weakest are December, January, November; output peaks in August and bottoms out in December. In all, 28.7% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against San Antonio

The nearest of the six largest modeled places is San Antonio, 347 km to the north, at 1,505 kWh per kW. Lyford models 40 kWh per kW (2.7%) above it. Lyford lies 3.05 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 Lyford is 1.0 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, 433 km north, where the same model gives 1,483 kWh per kW, so Lyford runs 62 above that figure. Against the Texas median place month by month, Lyford runs at least 2% higher in February, March, April, October. It runs at least 2% lower in July.

Electricity in Willacy CountyEIA-861

Electricity prices nearby

EIA lists AEP Texas Central in this county. Where Lyford is on AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Lyford 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 1,545 kWh at $237 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 Lyford. 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 Lyford 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 $238 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.

  • A model estimate for a generic system at this point, not a measurement and not a promise of output.
  • Shading, roof pitch, equipment and local rates will differ.
  • All prices on this site are in cents per kWh unless marked otherwise. Bills are US dollars per month.
