Sun on a roof in Dayton.
The PVWatts model puts a generic roof array in Dayton at 1,427 kWh a year for each kW of panels, using typical-year weather from a station 0.0 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How Dayton comparesderived from the figures above
Where Dayton sits.
Dayton ranks 1109th of 1220 Texas places modeled here, at the 9th percentile. Its 1,427 kWh per kW is below the Texas median of 1,515.

Against Houston
The nearest of the six largest modeled places is Houston, 50 km to the southwest, at 1,422 kWh per kW. Dayton models 5 kWh per kW (0.4%) 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 Houston's.
The second-nearest large place is Austin, 272 km west, where the same model gives 1,483 kWh per kW, so Dayton runs 56 below that figure. It runs at least 2% lower in January, February, March, April, May, June, July, August, September, November.
Electricity in Liberty CountyEIA-861
Electricity prices nearby
EIA lists CenterPoint Energy Houston Electric in this county. Where Dayton is on CenterPoint Energy Houston Electric's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Dayton 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 1,427 kWh at $219 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Entergy Texas Inc.: 13.89¢ per kWh, a bundled average, 469,094 residential customers across 27 counties.
- Sam Houston Electric Coop Inc: 14.18¢ per kWh, a bundled average, 88,424 residential customers across 10 counties.
- CenterPoint Energy: 5.41¢ per kWh, delivery charges only, before the retail energy price, 2,529,039 residential customers across 12 counties.
These utilities serve other parts of the county, which can include parts of Dayton. 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 Dayton 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 $220 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.
