Sun on a roof in Bastrop.
The PVWatts model puts a generic roof array in Bastrop at 1,465 kWh a year for each kW of panels, using typical-year weather from a station 2.9 km away. A modeled estimate for a standard setup, not a measurement of any roof.

Against Austin
The nearest of the six largest modeled places is Austin, 46 km to the northwest, at 1,483 kWh per kW. Bastrop models 18 kWh per kW (1.2%) below it. At 0.19 degrees of latitude apart, the two sit at almost the same sun angle, so geometry explains little. The weather station for Bastrop is 2.9 km from the modeled point, against 1.5 km for Austin, so part of the gap can come from which station's typical year was used.
The second-nearest large place is San Antonio, 137 km southwest, where the same model gives 1,505 kWh per kW, so Bastrop runs 40 below that figure. It runs at least 2% lower in February, March, April, May, July, September, December.
Electricity in Bastrop CountyEIA-861
Electricity prices nearby
EIA lists Oncor Electric Delivery in this county. Where Bastrop is on Oncor Electric Delivery's lines, homes buy energy from a retail electricity provider and the price depends on the plan. Parts of Bastrop 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 1,465 kWh at $224 per kW a year, plain multiplication and not a savings estimate or an offer.

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 Bastrop 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 $226 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.
