FAQS about Ground solar China

How big is China's ground-mounted solar power station?

The tool shows China ground mounted solar facilities occupied a surface of 2,467.7 km2 at the end of December 2020. Scientists led by the China Agricultural University have created a national-scale map and dataset of ground-mounted PV power stations in China.

Where is solar power generated in China?

Most of China's solar power is generated within its western provinces and is transferred to other regions of the country. In 2011, China owned the largest solar power plant in the world at the time, the Huanghe Hydropower Golmud Solar Park, which had a photovoltaic capacity of 200 MW.

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.

Are ground-mounted PV power stations in China based on Sentinel-2 imagery?

Scientists led by the China Agricultural University have created a national-scale map and dataset of ground-mounted PV power stations in China. The data is based on Sentinel-2 imagery from 2020 and has a spatial resolution of 10 meters.

Which land is used for PV power stations in China?

Fig. 1 Examples of PV power stations in China. The land used for PV power stations includes gobi (left), grassland (top), water bodies (right), mountain land (bottom), etc. The objective of this study is to provide the first publicly released 10-m national map of ground-mounted PV power stations of China in 2020.

Where are PV power plants located in China?

Eventually, we established a map of PV power plants in China by 2020, covering a total area of 2917 km2. We found that most PV power plants were situated on cropland, followed by barren land and grassland, based on the derived national PV map. In addition, the installation of PV power plants has generally decreased the vegetation cover.
