Sun on a roof in Goliad.
The PVWatts model puts a generic roof array in Goliad at 1,450 kWh a year for each kW of panels, using typical-year weather from a station 2.4 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How Goliad comparesderived from the figures above
Where Goliad sits.
Goliad ranks 1025th of 1220 Texas places modeled here, at the 16th percentile. Its 1,450 kWh per kW is below the Texas median of 1,515. The strongest months are July, August, June and the weakest are February, November, December; output peaks in July and bottoms out in February. In all, 29.7% 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, 141 km to the northwest, at 1,505 kWh per kW. Goliad models 55 kWh per kW (3.7%) below it. Goliad lies 0.79 degrees of latitude south of San Antonio, 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 (2.4 km and 2.2 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Austin, 185 km north, where the same model gives 1,483 kWh per kW, so Goliad runs 33 below that figure. It runs at least 2% lower in January, February, April, May, June, August, September, November.
Electricity in Goliad CountyEIA-861
Electricity prices nearby
EIA lists AEP Texas Central in this county. Where Goliad is on AEP Texas Central's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Goliad 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 1,450 kWh at $222 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Guadalupe Valley Elec Coop Inc: 11.83¢ per kWh, a bundled average, 95,358 residential customers across 13 counties.
- Victoria Electric Coop, Inc: 12.4¢ per kWh, a bundled average, 21,716 residential customers across 6 counties.
- Karnes Electric Coop Inc: 10.25¢ per kWh, a bundled average, 13,599 residential customers across 12 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 Goliad. 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 Goliad 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 $223 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.
