Against Dallas
The nearest of the six largest modeled places is Dallas, 79 km to the northwest, at 1,500 kWh per kW. Gun Barrel City models 19 kWh per kW (1.3%) below it. Gun Barrel City lies 0.46 degrees of latitude south of Dallas, which on sun angle alone would point the other way, so clouds, haze and the weather station's record carry the difference. The weather station for Gun Barrel City is 0.9 km from the modeled point, against 2.4 km for Dallas, so part of the gap can come from which station's typical year was used.
The second-nearest large place is Fort Worth, 125 km northwest, where the same model gives 1,535 kWh per kW, so Gun Barrel City runs 54 below that figure. It runs at least 2% lower in January, February, March, April, November, December.

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.
