How Alpine comparesderived from the figures above

Where Alpine sits.

Alpine ranks 15th of 1220 Texas places modeled here, at the 99th percentile. Its 1,783 kWh per kW is above the Texas median of 1,515. The strongest months are May, March, April and the weakest are December, November, January; output peaks in May and bottoms out in December. In all, 25.2% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against El Paso

The nearest of the six largest modeled places is El Paso, 311 km to the northwest, at 1,835 kWh per kW. Alpine models 52 kWh per kW (2.8%) below it. Alpine lies 1.49 degrees of latitude south of El Paso, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The two weather stations sit a similar distance from their points (1.1 km and 0.9 km), so station distance does little to explain the gap, and the weather record does the rest.

The second-nearest large place is San Antonio, 505 km east, where the same model gives 1,505 kWh per kW, so Alpine runs 278 above that figure. Against the Texas median place month by month, Alpine runs at least 2% higher in January, February, March, April, May, June, September, October, November, December. It runs at least 2% lower in July.

Electricity prices nearby

EIA lists AEP Texas North in this county. Where Alpine is on AEP Texas North's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Alpine 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 1,783 kWh at $273 per kW a year, plain multiplication and not a savings estimate or an offer.

Also listed in the county

• Rio Grande Electric Coop, Inc: 18.29¢ per kWh, a bundled average, 9,371 residential customers across 18 counties.
• AEP Texas North Company: 5.86¢ per kWh, delivery charges only, before the retail energy price, 158,488 residential customers across 51 counties.

These utilities serve other parts of the county, which can include parts of Alpine. 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 Alpine 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 $275 per kW a year as plain multiplication.
