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.

What is remote sensing derived dataset for large-scale photovoltaic power stations in China?

We provide a remote sensing derived dataset for large-scale ground-mounted photovoltaic (PV) power stations in China of 2020, which has high spatial resolution of 10 meters. The dataset is based on the Google Earth Engine (GEE) cloud computing platform via random forest classifier and active learning strategy.

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.

Why are photovoltaic installations moving eastward in China?

In contrast, it has moved southeastward annually from 2013 to 2019, to reduce transportation losses and costs, photovoltaic installations are gradually in the densely populated eastern region in China, and the photovoltaic to urban distance can also reflect this trend (Fig. 5 b).

How long will China's photovoltaic power stations last?

From the perspective of photovoltaic scrap time, suppose the lifetime of photovoltaics to be 25 years (Libra et al.,2023), it can be inferred from Fig. 3 b and Fig. 4 c that China's photovoltaic power stations will face widespread scrapping starting from 2038, which highlights the importance of planning for areas to be decommissioned.
