Where are photovoltaic panels located in China?

The photovoltaic panel areas in Hebei, Jiangsu, and Shandong were relatively large (132.84 km 2, 98.35 km 2, and 93.63 km 2), and accounted for about 63.71% of total photovoltaic panel area in the coastal regions. Moreover, these three provinces are the regions with the highest grid-connected capacity.

How can photovoltaic power generation help China's coastal regions?

Photovoltaic power generation is an effective way for China’s coastal regions to achieve energy decarbonization and environmentally sustainable development.

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.

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.

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.

What is the spatial resolution of photovoltaic power generation station data?

The photovoltaic power generation station data (PV_China_2020) in China in 2020 were obtained from the GEE platform, using the random forest algorithm. The data sources were Landsat images, and the spatial resolution was 30 m . In contrast, our PV map (2021_PV) had the higher spatial resolution of 10 m.
