Sun on a roof in Tyler.
The PVWatts model puts a generic roof array in Tyler at 1,463 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 Dallas
The nearest of the six largest modeled places is Dallas, 146 km to the west, at 1,500 kWh per kW. Tyler models 37 kWh per kW (2.5%) below it. Tyler lies 0.47 degrees of latitude south of Dallas, 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 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, 198 km west, where the same model gives 1,535 kWh per kW, so Tyler runs 72 below that figure. Against the Texas median place month by month, Tyler runs at least 2% higher in May. It runs at least 2% lower in January, February, March, June, July, August, September, November, December.
Electricity in Smith CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery in this county. Where Tyler is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Tyler 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 1,463 kWh at $224 per kW a year, plain multiplication and not a savings estimate or an offer.
Also listed in the county
- Southwestern Electric Power Co: 12.6¢ per kWh, a bundled average, 157,119 residential customers across 25 counties.
- Upshur Rural Elec Coop Corp: 12.71¢ per kWh, a bundled average, 44,971 residential customers across 10 counties.

These utilities serve other parts of the county, which can include parts of Tyler. 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 Tyler 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 $226 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.
