Sun on a roof in Hamilton.
The PVWatts model puts a generic roof array in Hamilton at 1,558 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 Hamilton comparesderived from the figures above
Where Hamilton sits.
Hamilton ranks 313th of 1220 Texas places modeled here, at the 74th percentile. Its 1,558 kWh per kW is above the Texas median of 1,515. The strongest months are July, August, June and the weakest are February, December, November; output peaks in July and bottoms out in February. In all, 29.1% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against Fort Worth
The nearest of the six largest modeled places is Fort Worth, 140 km to the northeast, at 1,535 kWh per kW. Hamilton models 23 kWh per kW (1.5%) above it. Hamilton lies 1.08 degrees of latitude south of Fort Worth, 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 (2.2 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is Austin, 160 km south, where the same model gives 1,483 kWh per kW, so Hamilton runs 75 above that figure. Against the Texas median place month by month, Hamilton runs at least 2% higher in January, March, April, July, October, November, December.
Electricity in Hamilton CountyEIA-861
Electricity prices nearby
EIA lists Texas-New Mexico Power in this county. Where Hamilton is on Texas-New Mexico Power's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Hamilton 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 1,558 kWh at $239 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- United Electric Coop Service Inc: 13.91¢ per kWh, a bundled average, 91,268 residential customers across 14 counties.
- Hamilton County Elec Coop Assn: 12.64¢ per kWh, a bundled average, 19,876 residential customers across 7 counties.
- Heart of Texas Electric Coop: 11.89¢ per kWh, a bundled average, 18,476 residential customers across 7 counties.
- Texas-New Mexico Power Co: 7.09¢ per kWh, delivery charges only, before the retail energy price, 237,930 residential customers across 42 counties.
These utilities serve other parts of the county, which can include parts of Hamilton. 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 Hamilton 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 $240 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.
