Sun on a roof in Brenham.
The PVWatts model puts a generic roof array in Brenham at 1,469 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.

Against Houston
The nearest of the six largest modeled places is Houston, 106 km to the southeast, at 1,422 kWh per kW. Brenham models 47 kWh per kW (3.3%) above it. Brenham lies 0.37 degrees of latitude north of Houston, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The two weather stations sit a similar distance from their points (2.2 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 Austin, 131 km west, where the same model gives 1,483 kWh per kW, so Brenham runs 14 below that figure. It runs at least 2% lower in January, March, April, June, July, September, December.

Electricity prices nearby
Brenham is served by its own municipal utility, City of Brenham. Municipal utilities in Texas generally sit outside retail choice, so homes in the city buy from the city utility. Its 2025 residential average was 10.36¢ per kWh, which would put the modeled 1,469 kWh at $152 per kW a year, plain multiplication and not a savings estimate.
Other providers listed in the county
- Entergy Texas Inc.: 13.89¢ per kWh, a bundled average, 469,094 residential customers across 27 counties.
- 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.
These serve areas outside the city utility. 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.

Size the array, see the kWh.
Scale the Brenham 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 $226 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.
