Sun on a roof in Impact.
The PVWatts model puts a generic roof array in Impact at 1,648 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 Impact comparesderived from the figures above
Where Impact sits.
Impact ranks 172nd of 1220 Texas places modeled here, at the 86th percentile. Its 1,648 kWh per kW is above the Texas median of 1,515. The strongest months are July, May, June and the weakest are December, February, November; output peaks in July and bottoms out in December. In all, 28.4% 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, 227 km to the east, at 1,535 kWh per kW. Impact models 113 kWh per kW (7.4%) above it. At 0.28 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. 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 Dallas, 281 km east, where the same model gives 1,500 kWh per kW, so Impact runs 148 above that figure. Against the Texas median place month by month, Impact runs at least 2% higher in January, February, March, April, May, June, July, September, October, November, December.
Electricity in Taylor CountyEIA-861
Electricity prices nearby
EIA lists AEP Texas North in this county. Where Impact is on AEP Texas North's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Impact 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 1,648 kWh at $252 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Taylor Electric Coop Inc: 16.14¢ per kWh, a bundled average, 19,215 residential customers across 11 counties.
- AEP Texas North Company: 5.86¢ per kWh, delivery charges only, before the retail energy price, 158,488 residential customers across 51 counties.
These utilities serve other parts of the county, which can include parts of Impact. 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 Impact 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 $254 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.
