Sun on a roof in Killeen.
The PVWatts model puts a generic roof array in Killeen at 1,530 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.

Against Austin
The nearest of the six largest modeled places is Austin, 87 km to the south, at 1,483 kWh per kW. Killeen models 47 kWh per kW (3.2%) above it. Killeen lies 0.78 degrees of latitude north of Austin, 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 (1.5 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 Fort Worth, 192 km north, where the same model gives 1,535 kWh per kW, so Killeen runs 5 below that figure. Against the Texas median place month by month, Killeen runs at least 2% higher in January, April. It runs at least 2% lower in July, October.
Electricity in Bell CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery in this county. Where Killeen is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Killeen 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 1,530 kWh at $234 per kW a year, plain multiplication and not a savings estimate or an offer.

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 Killeen 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 15.47¢ per kWh. At that rate the modeled output is worth $237 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.
