Sun on a roof in Boerne.

The PVWatts model puts a generic roof array in Boerne at 1,529 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.

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

How Boerne comparesderived from the figures above

Where Boerne sits.

Boerne ranks 55th of 157 Texas places modeled here, at the 66th percentile. Its 1,529 kWh per kW is above the Texas median of 1,518. The strongest months are July, August, June and the weakest are December, January, November; output peaks in July and bottoms out in December. In all, 28.9% of the year arrives in June, July and August, less than the 29.4% of the median place.

Against San Antonio

The nearest of the six largest modeled places is San Antonio, 41 km to the southeast, at 1,505 kWh per kW. Boerne models 24 kWh per kW (1.6%) above it. Boerne lies 0.32 degrees of latitude north of San Antonio, 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 2.2 km), so station distance does little to explain the gap, and the weather record does the rest.

The second-nearest large place is Austin, 111 km northeast, where the same model gives 1,483 kWh per kW, so Boerne runs 46 above that figure. Against the Texas median place month by month, Boerne runs at least 2% higher in February, March, October.

Electricity prices nearby

Boerne is served by its own municipal utility, Boerne Utilities. Municipal utilities in Texas generally sit outside retail choice, so homes in the city buy from the city utility. No price for it is on this site, so the Texas average above is the only rate used.

Other providers listed in the county

These serve areas outside the city utility. 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.

Size the array, see the kWh.

Scale the Boerne 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 $237 per kW a year as plain multiplication.

Modeled estimate

About - kWh in an average month. Priced at the chosen rate that energy comes to - a year, by multiplication only.

Assumes the same tilt, direction and equipment as the model below. Real output depends on the roof, shade, equipment and weather.

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.
