Sun on a roof in Danbury.

The PVWatts model puts a generic roof array in Danbury at 1,459 kWh a year for each kW of panels, using typical-year weather from a station 2.4 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Scroll from January to December: the noon sun over Danbury climbs and falls, and the modeled output follows it.

How Danbury comparesderived from the figures above

Where Danbury sits.

Danbury ranks 986th of 1220 Texas places modeled here, at the 19th percentile. Its 1,459 kWh per kW is below the Texas median of 1,515. The strongest months are May, June, July and the weakest are December, February, January; output peaks in May 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.

Closest modeled neighbors

  • Angleton, 10 km southwest: 1,459 kWh per kW, 0 the same as Danbury.
  • Liverpool, 11 km northeast: 1,447 kWh per kW, 12 less than Danbury.

  • Holiday Lakes, 17 km west: 1,445 kWh per kW, 14 less than Danbury.
  • Bailey's Prairie, 17 km southwest: 1,458 kWh per kW, 1 less than Danbury.
  • Richwood, 20 km south: 1,448 kWh per kW, 11 less than Danbury.
  • Hillcrest Village, 22 km northeast: 1,453 kWh per kW, 6 less than Danbury.

Against Houston

The nearest of the six largest modeled places is Houston, 62 km to the north, at 1,422 kWh per kW. Danbury models 37 kWh per kW (2.6%) above it. Danbury lies 0.56 degrees of latitude south of Houston, and the sun stands higher in the sky the further south you go, which matches its higher modeled output. The two weather stations sit a similar distance from their points (2.4 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 Austin, 260 km northwest, where the same model gives 1,483 kWh per kW, so Danbury runs 24 below that figure. It runs at least 2% lower in January, February, April, June, July, August, December.

Electricity prices nearby

EIA lists CenterPoint Energy Houston Electric and Texas-New Mexico Power in this county. Where Danbury is on CenterPoint Energy Houston Electric and Texas-New Mexico Power's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Danbury 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 1,459 kWh at $224 per kW a year, plain multiplication and not a savings estimate or an offer.

Also listed in the county

  • Jackson Electric Coop, Inc: 14.55¢ per kWh, a bundled average, 15,670 residential customers across 6 counties.
  • CenterPoint Energy: 5.41¢ per kWh, delivery charges only, before the retail energy price, 2,529,039 residential customers across 12 counties.

These utilities serve other parts of the county, which can include parts of Danbury. 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 Danbury 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 $225 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.

  • A model estimate for a generic system at this point, not a measurement and not a promise of output.
  • Shading, roof pitch, equipment and local rates will differ.
  • All prices on this site are in cents per kWh unless marked otherwise. Bills are US dollars per month.
