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.

Is PV power a problem in China?

Meanwhile, PV power has gradually raised huge concerns in China. According to statistics 7, the installed capacity of PV power in China was only 100 MW in 2007, but grew rapidly to 205,000 MW in 2019, with an average growth of 17,075 MW per year.

Where are PV power stations located in China?

It should also be noted that with the rapid development of China’s PV industry, increasingly more eastern provinces built large-scale PV power stations, including Jiangsu, Anhui and Shandong Province. Areas of PV power stations for each province of China.

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.

Are PV areas overestimated in Zhang's study?

However, as the PV polygons from Zhang's study included several non-PV pixels around PV polygons (Fig. 10 a and b), resulting in the overestimation of PV areas in their study. Table 2. Comparison of PV solar power plant maps between our study and Zhang's study.

How does land cover change in PV solar power plants in Gansu?

Land cover change from the expansion of PV solar power plants The land-use change analysis shows that the newly constructed PV solar power plants in Gansu are mainly converted from four land cover types: gobi (63.9%), sparse grasslands (12.7%), other built-up lands (e.g., large industrial areas, and mines) (8.9%), and croplands (7.6%) (Fig. 9 a).
