Sun on a roof in Conroe.
The PVWatts model puts a generic roof array in Conroe at 1,395 kWh a year for each kW of panels, using typical-year weather from a station 1.9 km away. A modeled estimate for a standard setup, not a measurement of any roof.

How Conroe comparesderived from the figures above
Where Conroe sits.
Conroe ranks 155th of 157 Texas places modeled here, at the 2nd percentile. Its 1,395 kWh per kW is below the Texas median of 1,518. The strongest months are July, August, May and the weakest are February, December, January; output peaks in July and bottoms out in February. In all, 29.2% of the year arrives in June, July and August, less than the 29.4% of the median place.

Against Houston
The nearest of the six largest modeled places is Houston, 61 km to the south, at 1,422 kWh per kW. Conroe models 27 kWh per kW (1.9%) below it. Conroe lies 0.54 degrees of latitude north of Houston, and the sun stands higher in the sky the further south you go, which matches its lower modeled output. The two weather stations sit a similar distance from their points (1.9 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, 218 km west, where the same model gives 1,483 kWh per kW, so Conroe runs 88 below that figure. It runs at least 2% lower in January, February, March, April, May, June, July, August, September, October, November, December.

Size the array, see the kWh.
Scale the Conroe 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 $216 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.
