Where does PV power come from in China?

However, most of the PV potential in China is distributed in sparsely populated regions such as northwest and Tibet of China, and more than 95% of PV power generation in these areas is centralized PV power generation .

How big are PV power plants in China?

The total area of the PV power plants in China is about 897 km2, based on Dunnett's dataset. We manually modified this dataset with Google Earth's background to ensure that the PV samples are located inside the PV power plants.

Can machine learning map PV power plants across China?

This study developed a workflow, combining machine learning and visual interpretation methods with big satellite data, to map PV power plants across China. We applied a pixel-based random forest (RF) model to classify the PV power plants from composite images in 2020 with a 30 m spatial resolution on the Google Earth Engine (GEE).

Do PV power plants reduce vegetation in China?

The PV power plants in China are more likely to be installed in suitable natural conditions but with low power demand or in areas with high local energy demand. We also found that installing PV power plants will generally decrease the vegetation. Our dataset is conducive to policy management and environmental assessment.

Does China have a potential for solar PV power station installation & generation?

The results of this study indicated that China, as one of the fast-growing countries in the global south, shows outstanding potential for solar PV power station installation and generation potential.

Do misclassified PV power plants still exist in China?

A large number of misclassified PV power plants due to commission errors in the machine learning step still exists in China. After transferring the pixel clusters to objects of vectors, we have spent dozens of hours on visual interpretation work to filter the misclassification regions with commission error.
