Sun on a roof in Diboll.
The PVWatts model puts a generic roof array in Diboll at 1,374 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 Diboll comparesderived from the figures above
Where Diboll sits.
Diboll ranks 1189th of 1220 Texas places modeled here, at the 3rd percentile. Its 1,374 kWh per kW is below the Texas median of 1,515. The strongest months are August, July, May and the weakest are February, January, December; output peaks in August and bottoms out in February. In all, 29.4% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against Houston
The nearest of the six largest modeled places is Houston, 166 km to the south, at 1,422 kWh per kW. Diboll models 48 kWh per kW (3.4%) below it. Diboll lies 1.4 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, 259 km northwest, where the same model gives 1,500 kWh per kW, so Diboll runs 126 below that figure. It runs at least 2% lower in January, February, March, April, May, June, July, August, September, October, November, December.
Electricity in Angelina CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery in this county. Where Diboll is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Diboll 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 1,374 kWh at $210 per kW a year, plain multiplication and not a savings estimate or an offer.

- Sam Houston Electric Coop Inc: 14.18¢ per kWh, a bundled average, 88,424 residential customers across 10 counties.
- Houston County Elec Coop Inc: 15.28¢ per kWh, a bundled average, 21,761 residential customers across 9 counties.
- Jasper-Newton Elec Coop, Inc: 14.1¢ per kWh, a bundled average, 21,316 residential customers across 5 counties.

These utilities serve other parts of the county, which can include parts of Diboll. 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 Diboll 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 $212 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.
