Against Austin
The nearest of the six largest modeled places is Austin, 71 km to the southeast, at 1,483 kWh per kW. Highland Haven models 41 kWh per kW (2.8%) above it. Highland Haven lies 0.31 degrees of latitude north of Austin, 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 (1.9 km and 1.5 km), so station distance does little to explain the gap, and the weather record does the rest.
The second-nearest large place is San Antonio, 128 km south, where the same model gives 1,505 kWh per kW, so Highland Haven runs 19 above that figure. Against the Texas median place month by month, Highland Haven runs at least 2% higher in January, November, December. It runs at least 2% lower in March, May.

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.
