Sun on a roof in Atlanta.
The PVWatts model puts a generic roof array in Atlanta at 1,406 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.
A year on one roof.
Scroll from January to December: the noon sun over Atlanta climbs and falls, and the modeled output follows it.

How Atlanta comparesderived from the figures above
Where Atlanta sits.
Atlanta ranks 1143rd of 1220 Texas places modeled here, at the 6th percentile. Its 1,406 kWh per kW is below the Texas median of 1,515. The strongest months are July, August, June and the weakest are February, December, November; output peaks in July and bottoms out in February. In all, 29.9% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against Dallas
The nearest of the six largest modeled places is Dallas, 245 km to the west, at 1,500 kWh per kW. Atlanta models 94 kWh per kW (6.3%) below it. Atlanta lies 0.32 degrees of latitude north of Dallas, and the sun stands higher in the sky the further south you go, which matches its lower modeled output. 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, 299 km west, where the same model gives 1,535 kWh per kW, so Atlanta runs 129 below that figure. It runs at least 2% lower in January, February, March, April, May, June, July, August, September, October, November, December.

Providers listed in the county
- Southwestern Electric Power Co: 12.6¢ per kWh, a bundled average, 157,119 residential customers across 25 counties.
- Upshur Rural Elec Coop Corp: 12.71¢ per kWh, a bundled average, 44,971 residential customers across 10 counties.
- Bowie-Cass Electric Coop, Inc: 13.35¢ per kWh, a bundled average, 34,727 residential customers across 6 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 1,406 kWh would come to $177 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Atlanta 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 $217 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.
