Photovoltaic panels on Yesanpo Mountain

Where are large-scale photovoltaic solar panels installed?

Large-scale photovoltaic solar panels have been installed on the Taihang Mountains in Shexian county, North China's Hebei province, to make use of large mountainous areas and to promote clean energy. The installed capacity of the photovoltaic systems, which convert light into electricity, is expected to reach 321 megawatts annually.

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.

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.

What land is used for PV power stations?

The land used for PV power stations includes gobi (left), grassland (top), water bodies (right), mountain land (bottom), etc. As for PV power station mapping, previous methods mainly focused on field survey and visual inspection, where manual annotation was performed to delineate the locations or boundaries based on the remote sensing imagery.

What is the slope of a PV power station?

To further investigate this issue, we also calculated the histogram of land slope in each direction (Fig. 4b). It depicts that most of the PV power stations in the northern parts (i.e., north, northeast, and northwest) have a slope of below 5°, i.e., most lying on the flatten ground instead of the nightside of the mountain.
