How many ground-mounted PV power stations are there in China?

According to our dataset, China has a total of 2467.7 km 2 ground-mounted PV power stations in 2020. The top three largest provinces refer to Xinjiang, Inner Mongolia and Qinghai, whose PV area ratio are 14.92%, 12.49% and 11.26%, respectively, with a total of nearly 40% of all the PV power stations of China.

Will PV power play a role in China's future?

It should be noted that China’s central government released the Carbon Peak and Carbon Neutrality strategy in 2020, which committed that China’s carbon emissions would reach the peak by 2030 and achieve carbon neutrality by 2060 8. Therefore, it is predictable that PV power would play an increasingly essential role in the near future.

Does China have a spatial map of PV power stations?

Although some researchers released several PV power station maps, most only met a medium resolution of 30 meters 9, 10. There thus still lacks a national map of China’s PV power stations with a higher spatial resolution (i.e., 10 meters) that could provide a global understanding of PV’s spatial deployment patterns.

Can random forest predict PV power stations of China Parallelly on Gee?

Finally, the trained random forest model is adopted to predict PV power stations of China parallelly on GEE. Technical validation has been carefully performed across China which achieved a satisfactory accuracy over 89%.
