Sun on a roof in Garland.
The PVWatts model puts a generic roof array in Garland at 1,522 kWh a year for each kW of panels, using typical-year weather from a station 2.4 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, 19 km to the southwest, at 1,500 kWh per kW. Garland models 22 kWh per kW (1.5%) above it. At 0.12 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 (2.4 km and 2.4 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Fort Worth, 69 km west, where the same model gives 1,535 kWh per kW, so Garland runs 13 below that figure. Against the Texas median place month by month, Garland runs at least 2% higher in January, April, June, August, September, December. It runs at least 2% lower in July, November.

Electricity prices nearby
Garland is served by its own municipal utility, City of Garland. Municipal utilities in Texas generally sit outside retail choice, so homes in the city buy from the city utility. Its 2025 residential average was 13.68¢ per kWh, which would put the modeled 1,522 kWh at $208 per kW a year, plain multiplication and not a savings estimate.
Other providers listed in the county
- Denton County Elec Coop, Inc: 13.18¢ per kWh, a bundled average, 310,805 residential customers across 6 counties.
- Grayson-Collin Elec Coop, Inc: 17.04¢ per kWh, a bundled average, 97,950 residential customers across 4 counties.
- Farmers Electric Coop, Inc: 11.95¢ per kWh, a bundled average, 88,221 residential customers across 12 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 serve areas outside the city utility. 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 Garland 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 $235 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.
