Sun on a roof in McLean.
The PVWatts model puts a generic roof array in McLean at 1,685 kWh a year for each kW of panels, using typical-year weather from a station 2.9 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How McLean comparesderived from the figures above
Where McLean sits.
McLean ranks 123rd of 1220 Texas places modeled here, at the 90th percentile. Its 1,685 kWh per kW is above the Texas median of 1,515. The strongest months are July, June, May and the weakest are November, December, January; output peaks in July and bottoms out in November. In all, 28.6% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against Fort Worth
The nearest of the six largest modeled places is Fort Worth, 405 km to the southeast, at 1,535 kWh per kW. McLean models 150 kWh per kW (9.8%) above it. McLean lies 2.45 degrees of latitude north of Fort Worth, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The weather station for McLean is 2.9 km from the modeled point, against 1.5 km for Fort Worth, so part of the gap can come from which station's typical year was used.
The second-nearest large place is Dallas, 445 km southeast, where the same model gives 1,500 kWh per kW, so McLean runs 185 above that figure. Against the Texas median place month by month, McLean runs at least 2% higher in January, February, March, April, May, June, July, August, September, October, November, December.

- Greenbelt Electric Coop, Inc: 17.88¢ per kWh, a bundled average, 3,929 residential customers across 9 counties.
They are the largest bundled providers 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. Priced at the first provider's average, the modeled 1,685 kWh would come to $235 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the McLean 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 $259 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.
