Rate & Roof

Odessa, TXLocal --:--Sun now --Daylight today --

Sun on a roof in Odessa.

The PVWatts model puts a generic roof array in Odessa at 1,759 kWh a year for each kW of panels, using typical-year weather from a station 1.5 km away. A modeled estimate for a standard setup, not a measurement of any roof.

A year on one roof.

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

How Odessa comparesderived from the figures above

Where Odessa sits.

Odessa ranks 4th of 157 Texas places modeled here, at the 98th percentile. Its 1,759 kWh per kW is above the Texas median of 1,518. The strongest months are May, July, April and the weakest are December, November, January; output peaks in May and bottoms out in December. In all, 27.7% of the year arrives in June, July and August, less than the 29.4% of the median place.

Against El Paso

The nearest of the six largest modeled places is El Paso, 385 km to the west, at 1,835 kWh per kW. Odessa models 76 kWh per kW (4.1%) below it. At 0.03 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The two weather stations sit a similar distance from their points (1.5 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, 454 km southeast, where the same model gives 1,505 kWh per kW, so Odessa runs 254 above that figure. Against the Texas median place month by month, Odessa runs at least 2% higher in January, February, March, April, May, June, July, August, September, October, November, December.

Electricity in Midland County, Ector CountyEIA-861

Electricity prices nearby

EIA lists Oncor Electric Delivery in this county. Where Odessa is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Odessa 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 1,759 kWh at $269 per kW a year, plain multiplication and not a savings estimate or an offer.

Also listed in the county

  • Southwestern Public Service Co: 13.94¢ per kWh, a bundled average, 223,685 residential customers across 45 counties.
  • Oncor Electric Delivery Company LLC: 5.64¢ per kWh, delivery charges only, before the retail energy price, 3,545,814 residential customers across 99 counties.

These utilities serve other parts of the county, which can include parts of Odessa. 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 Odessa 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 15.47¢ per kWh. At that rate the modeled output is worth $272 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.

  • 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.
