Sun on a roof in Irving.
The PVWatts model puts a generic roof array in Irving at 1,499 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.

Against Dallas
The nearest of the six largest modeled places is Dallas, 20 km to the southeast, at 1,500 kWh per kW. Irving models 1 kWh per kW (0.1%) below it. The two figures are within 1 percent, which is about the size of the difference you get from two neighboring weather stations alone, so this page's result is effectively the same as Dallas's.
The second-nearest large place is Fort Worth, 37 km west, where the same model gives 1,535 kWh per kW, so Irving runs 36 below that figure. Against the Texas median place month by month, Irving runs at least 2% higher in May, October. It runs at least 2% lower in April, August, November.
Electricity in Dallas CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery and Texas-New Mexico Power in this county. Most homes in Irving buy energy from a retail electricity provider over the lines of Oncor Electric Delivery and Texas-New Mexico Power, so the price depends on the plan you choose. 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 1,499 kWh at $230 per kW a year, plain multiplication and not a savings estimate or an offer.

These utilities serve other parts of the county, which can include parts of Irving. 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 Irving 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 $232 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.
