Sun on a roof in Lexington.
The PVWatts model puts a generic roof array in Lexington at 1,492 kWh a year for each kW of panels, using typical-year weather from a station 1.0 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Against Austin
The nearest of the six largest modeled places is Austin, 72 km to the west, at 1,483 kWh per kW. Lexington models 9 kWh per kW (0.6%) above 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 Austin's.
The second-nearest large place is Houston, 170 km southeast, where the same model gives 1,422 kWh per kW, so Lexington runs 70 above that figure. It runs at least 2% lower in February, March, June, July, December.

Providers listed in the county
- Bluebonnet Electric Coop, Inc: 11.59¢ per kWh, a bundled average, 119,030 residential customers across 14 counties.
- Fayette Electric Coop, Inc: 12.53¢ per kWh, a bundled average, 14,439 residential customers across 8 counties.
- Bartlett Electric Coop, Inc: 15.23¢ per kWh, a bundled average, 12,402 residential customers across 5 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 1,492 kWh would come to $173 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Lexington 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 $230 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.
