Are PV panels suitable for large-scale applications in China's coastal regions?

The area of PV panels in China’s coastal regions is rapidly increasing, due to the huge demand for renewable energy. However, a rapid, accurate, and robust PV panel mapping approach, and a practical PV panel classification strategy for large-scale applications have not been established.

How many photovoltaic panels are there in China in 2021?

The total area of photovoltaic panels in China’s coastal regions in 2021 was about 510.78 km 2, and the average PV panel density reached 378.77 m 2 per km 2. The photovoltaic panel area in the different regions, and the cumulative grid-connected capacity in 2021 are shown in Figure 6 d.

What percentage of solar panels are made in China?

China’s solar PV manufacturing also accounts for about 71 per cent of the world’s total capacity. With over 260 PV module manufacturers in China, 35.4 GW of PV products were exported in the first five months this year, representing a 34 per cent year-on-year increase. In fact, China dominates all sectors of the world’s PV solar panel production.

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.

Can spectral and textural features identify PV panels in coastal China?

Here, we developed a new approach that uses spectral and textural features to identify and map the PV panels there were in coastal China in 2021 using multispectral instrument (MSI) and synthetic aperture radar (SAR) images, and the Google Earth Engine (GEE), to differentiate PV panels according to their underlying surface properties.

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.
