Sun on a roof in Somerset.
The PVWatts model puts a generic roof array in Somerset at 1,504 kWh a year for each kW of panels, using typical-year weather from a station 2.2 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How Somerset comparesderived from the figures above
Where Somerset sits.
Somerset ranks 714th of 1220 Texas places modeled here, at the 42nd percentile. Its 1,504 kWh per kW is below the Texas median of 1,515. The strongest months are August, July, June and the weakest are February, December, November; output peaks in August and bottoms out in February. In all, 29.8% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against San Antonio
The nearest of the six largest modeled places is San Antonio, 29 km to the northeast, at 1,505 kWh per kW. Somerset models 1 kWh per kW (0.1%) below 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 San Antonio's.
The second-nearest large place is Austin, 148 km northeast, where the same model gives 1,483 kWh per kW, so Somerset runs 21 above that figure. Against the Texas median place month by month, Somerset runs at least 2% higher in January, March, August. It runs at least 2% lower in February, April, July, November.

Providers listed in the county
- City of San Antonio: 12.4¢ per kWh, a bundled average, 888,946 residential customers across 8 counties.
- Pedernales Electric Coop, Inc: 12.75¢ per kWh, a bundled average, 420,753 residential customers across 24 counties.
- Guadalupe Valley Elec Coop Inc: 11.83¢ per kWh, a bundled average, 95,358 residential customers across 13 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 1,504 kWh would come to $186 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Somerset 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 $232 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.
