Sun on a roof in Riverside.
The PVWatts model puts a generic roof array in Riverside at 1,412 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 Riverside comparesderived from the figures above
Where Riverside sits.
Riverside ranks 1134th of 1220 Texas places modeled here, at the 7th percentile. Its 1,412 kWh per kW is below the Texas median of 1,515. The strongest months are May, July, August and the weakest are December, January, February; output peaks in May and bottoms out in December. In all, 29.5% of the year arrives in June, July and August, more than the 29.3% of the median place.

Against Houston
The nearest of the six largest modeled places is Houston, 118 km to the south, at 1,422 kWh per kW. Riverside models 10 kWh per kW (0.7%) below it. The two figures are within 1 percent, which is about the size of the difference you get from two neighboring weather stations alone, so this page's result is effectively the same as Houston's.
The second-nearest large place is Austin, 233 km west, where the same model gives 1,483 kWh per kW, so Riverside runs 71 below that figure. It runs at least 2% lower in January, February, March, April, June, July, August, September, October, November, December.

Providers listed in the county
- Entergy Texas Inc.: 13.89¢ per kWh, a bundled average, 469,094 residential customers across 27 counties.
- Sam Houston Electric Coop Inc: 14.18¢ per kWh, a bundled average, 88,424 residential customers across 10 counties.
- Mid-South Electric Coop Assn: 15.37¢ per kWh, a bundled average, 37,251 residential customers across 6 counties.
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. Priced at the first provider's average, the modeled 1,412 kWh would come to $196 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the Riverside 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 $217 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.

Payback, buyback.
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.
