Sun on a roof in Seadrift.
The PVWatts model puts a generic roof array in Seadrift at 1,527 kWh a year for each kW of panels, using typical-year weather from a station 2.0 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, 201 km to the northeast, at 1,422 kWh per kW. Seadrift models 105 kWh per kW (7.4%) above it. Seadrift lies 1.38 degrees of latitude south of Houston, and the sun stands higher in the sky the further south you go, which matches its higher modeled output. The two weather stations sit a similar distance from their points (2.0 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 San Antonio, 211 km northwest, where the same model gives 1,505 kWh per kW, so Seadrift runs 22 above that figure. Against the Texas median place month by month, Seadrift runs at least 2% higher in January, May, November, December. It runs at least 2% lower in April, July.
Electricity in Calhoun CountyEIA-861
Electricity prices nearby
EIA lists AEP Texas Central in this county. Where Seadrift is on AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Seadrift may instead be served by a co-op or utility listed below, which sets its own rates; check your bill. For scale only, the median 2025 average price across the 60 Texas retail providers on this site is 15.32¢ per kWh, which would put the modeled 1,527 kWh at $234 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Victoria Electric Coop, Inc: 12.4¢ per kWh, a bundled average, 21,716 residential customers across 6 counties.
- Jackson Electric Coop, Inc: 14.55¢ per kWh, a bundled average, 15,670 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 utilities serve other parts of the county, which can include parts of Seadrift. 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 Seadrift 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 $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.

Payback, buyback.
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.
