Banshi Village Photovoltaic Power Station Introduction

Can epvi improve the accuracy of national-scale PV power stations?

EPVI inclusion can improve the mapping accuracy of national-scale PV power stations, with China’s total PV installation area in 2020 estimated as 2635.64 km 2, achieving an overall accuracy of 0.9756 and a Kappa coefficient of 0.9394.

How big is China's PV power station?

China’s total PV power station area in 2020 was estimated as 2635.64 km 2. China’s PV power generation in 2020 was calculated to be 238.65 TWh. This power amount is equivalent to reducing carbon emissions by 149.63 million tons. Evaluation results favor Sustainable Development Goals and carbon neutrality.

Which slopes are not suitable for building PV power stations?

Firstly, based on a priori knowledge in the field of PV, regions with slopes > 25° are not suitable for building PV power stations due to high construction and maintenance costs, thereby filtering out the noise with slopes > 25° .

How is the spatial distribution of China's PV power stations mapped?

The spatial distribution of China's PV power stations in 2020 was mapped based on the GEE platform by including the proposed EPVI to provide real-world data support for further scientific evaluation.

What percentage of PV power stations are located on grasslands?

The statistical results showed that in 2020, 40.89 % of PV power stations were established on grasslands, 24.88 % on croplands, 17.01 % and 14.14 % on barren lands and buildings, 2.12 % on water, and only 0.96 % on forests or shrubs. Fig. 11. The statistics of land-use coverage type occupied by China’s PV power stations in 2020. 3.3.

How are PV arrays arranged in the construction of PV power stations?

In the construction of PV power stations, the distribution of PV arrays is usually concentrated in areas with gentle terrain, while their arrangement in areas with undulating terrain takes more consideration of the influence of topographic factors, resulting in a large variance in spacing between PV arrays.
