Sun on a roof in Frost.
The PVWatts model puts a generic roof array in Frost at 1,518 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.

How Frost comparesderived from the figures above
Where Frost sits.
Frost ranks 572nd of 1220 Texas places modeled here, at the 53rd percentile. Its 1,518 kWh per kW is above the Texas median of 1,515. The strongest months are July, June, August and the weakest are February, January, December; output peaks in July and bottoms out in February. In all, 30.2% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against Dallas
The nearest of the six largest modeled places is Dallas, 79 km to the north, at 1,500 kWh per kW. Frost models 18 kWh per kW (1.2%) above it. Frost lies 0.71 degrees of latitude south of Dallas, 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 (1.5 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 Fort Worth, 93 km northwest, where the same model gives 1,535 kWh per kW, so Frost runs 17 below that figure. Against the Texas median place month by month, Frost runs at least 2% higher in June, September. It runs at least 2% lower in January, February, May.
Electricity in Navarro CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery in this county. Where Frost is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Frost 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 1,518 kWh at $233 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Navarro County Elec Coop, Inc: 12.92¢ per kWh, a bundled average, 19,029 residential customers across 5 counties.
- Oncor Electric Delivery Company LLC: 5.64¢ per kWh, delivery charges only, before the retail energy price, 3,545,814 residential customers across 99 counties.
These utilities serve other parts of the county, which can include parts of Frost. 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 Frost 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 $234 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.
