Sun on a roof in La Grange.
The PVWatts model puts a generic roof array in La Grange at 1,487 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.

Against Austin
The nearest of the six largest modeled places is Austin, 94 km to the northwest, at 1,483 kWh per kW. La Grange models 4 kWh per kW (0.3%) 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, 144 km east, where the same model gives 1,422 kWh per kW, so La Grange runs 65 above that figure. Against the Texas median place month by month, La Grange runs at least 2% higher in February, May, November. It runs at least 2% lower in January, March, July, August, September, December.

- San Bernard Electric Coop, Inc: 14.11¢ per kWh, a bundled average, 32,557 residential customers across 8 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 1,487 kWh would come to $172 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the La Grange 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 $229 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.
