Sun on a roof in Brownsville.
The PVWatts model puts a generic roof array in Brownsville at 1,517 kWh a year for each kW of panels, using typical-year weather from a station 1.5 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Against San Antonio
The nearest of the six largest modeled places is San Antonio, 399 km to the north, at 1,505 kWh per kW. Brownsville models 12 kWh per kW (0.8%) 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 San Antonio's.
The second-nearest large place is Houston, 468 km northeast, where the same model gives 1,422 kWh per kW, so Brownsville runs 95 above that figure. Against the Texas median place month by month, Brownsville runs at least 2% higher in February, March, April, May, October. It runs at least 2% lower in January, July, September, December.
Electricity in Cameron CountyEIA-861
Electricity prices nearby
Brownsville is served by its own municipal utility, Brownsville Public Utilities Board. Municipal utilities in Texas generally sit outside retail choice, so homes in the city buy from the city utility. Its 2025 residential average was 11.22¢ per kWh, which would put the modeled 1,517 kWh at $170 per kW a year, plain multiplication and not a savings estimate.
Other providers listed in the county
- Magic Valley Electric Coop Inc: 10.51¢ per kWh, a bundled average, 129,596 residential customers across 6 counties.
- AEP Texas Central Company: 5.91¢ per kWh, delivery charges only, before the retail energy price, 793,896 residential customers across 44 counties.
These serve areas outside the city utility. They are the largest bundled providers, and the largest delivery-only one, 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 Brownsville 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 15.47¢ per kWh. At that rate the modeled output is worth $235 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.
