Sun on a roof in Mission.
The PVWatts model puts a generic roof array in Mission at 1,598 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.

How Mission comparesderived from the figures above
Where Mission sits.
Mission ranks 13th of 157 Texas places modeled here, at the 92nd percentile. Its 1,598 kWh per kW is above the Texas median of 1,518.

Against San Antonio
The nearest of the six largest modeled places is San Antonio, 363 km to the north, at 1,505 kWh per kW. Mission models 93 kWh per kW (6.2%) above it. Mission lies 3.26 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 (1.5 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 Austin, 459 km north, where the same model gives 1,483 kWh per kW, so Mission runs 115 above that figure. Against the Texas median place month by month, Mission runs at least 2% higher in January, February, March, April, May, June, August, October, November, December.
Electricity in Hidalgo CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery and AEP Texas Central in this county. Where Mission is on Oncor Electric Delivery and AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Mission 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 1,598 kWh at $245 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Magic Valley Electric Coop Inc: 10.51¢ per kWh, a bundled average, 129,596 residential customers across 6 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 Mission. 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 Mission 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 $247 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.
