Sun on a roof in Chester.
The PVWatts model puts a generic roof array in Chester at 1,346 kWh a year for each kW of panels, using typical-year weather from a station 2.2 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How Chester comparesderived from the figures above
Where Chester sits.
Chester ranks 1214th of 1220 Texas places modeled here, at the 1st percentile. Its 1,346 kWh per kW is below the Texas median of 1,515. The strongest months are May, August, July and the weakest are December, January, February; output peaks in May and bottoms out in December. In all, 29.1% of the year arrives in June, July and August, less than the 29.3% of the median place.

Against Houston
The nearest of the six largest modeled places is Houston, 147 km to the southwest, at 1,422 kWh per kW. Chester models 76 kWh per kW (5.3%) below it. Chester lies 1.13 degrees of latitude north of Houston, and the sun stands higher in the sky the further south you go, which matches its lower modeled output. The two weather stations sit a similar distance from their points (2.2 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 Dallas, 292 km northwest, where the same model gives 1,500 kWh per kW, so Chester runs 154 below that figure. It runs at least 2% lower in January, February, March, April, May, June, July, August, September, October, November, December.

Providers 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.
They are the largest bundled providers 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. Priced at the first provider's average, the modeled 1,346 kWh would come to $187 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Chester 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 $207 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.
