Sun on a roof in China.
The PVWatts model puts a generic roof array in China at 1,410 kWh a year for each kW of panels, using typical-year weather from a station 1.1 km away. A modeled estimate for a standard setup, not a measurement of any roof.
A year on one roof.
Scroll from January to December: the noon sun over China climbs and falls, and the modeled output follows it.

How China comparesderived from the figures above
Where China sits.
China ranks 1139th of 1220 Texas places modeled here, at the 7th percentile. Its 1,410 kWh per kW is below the Texas median of 1,515. The strongest months are May, July, June and the weakest are December, February, January; output peaks in May and bottoms out in December. In all, 27.9% of the year arrives in June, July and August, less than the 29.3% of the median place.
Closest modeled neighbors
- Nome, 8 km west: 1,407 kWh per kW, 3 less than China.
- Sour Lake, 13 km northwest: 1,404 kWh per kW, 6 less than China.
- Bevil Oaks, 14 km northeast: 1,387 kWh per kW, 23 less than China.
- Beaumont, 19 km east: 1,401 kWh per kW, 9 less than China.
- Rose Hill Acres, 22 km northeast: 1,393 kWh per kW, 17 less than China.

- Lumberton, 26 km northeast: 1,364 kWh per kW, 46 less than China.
- Taylor Landing, 28 km southeast: 1,445 kWh per kW, 35 more than China.
- Rose City, 29 km east: 1,392 kWh per kW, 18 less than China.
Against Houston
The nearest of the six largest modeled places is Houston, 105 km to the west, at 1,422 kWh per kW. China models 12 kWh per kW (0.8%) 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, 329 km west, where the same model gives 1,483 kWh per kW, so China runs 73 below that figure. It runs at least 2% lower in February, March, April, May, 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.
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 1,410 kWh would come to $196 per kW a year, plain multiplication and not a savings estimate.

Size the array, see the kWh.
Scale the China 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.

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.
