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.
A total of 676 counties in China are currently serving as pilots, and 100 % of the available roofs of their public buildings, such as party and government offices, institutions, public schools, and public hospitals, must be installed with PV .
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.
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.
Land is a fundamental resource for the deployment of PV systems, and PV power projects are established on various types of land. As of the end of 2022, China has amassed an impressive 390 million kW of installed PV capacity, occupying approximately 0.8 million km2 of land .
According to the photovoltaic power installation distribution, the spatial-temporal characteristics of the photovoltaic power installation in China can be depicted. The photovoltaic power development stages could be classified into Full operation, Partial operation, Announced construction, Permitted construction, and Under construction.

Solar energy in the EU
Furthermore, the solar energy sector in Europe lacks skilled workers, and the energy storage and conversion rate are also in need of improvement. Lastly, as pointed out in a recent EPRS note on solar as a source of EU energy security, China is the dominant producer of solar PV panels, which creates a risk of a new dependency from this supplier.
