How to assess PV power generation potential of rooftop in China?

In this paper, we present an assessment method for the PV power generation potential of rooftop in China. Using machine learning model processes the big data that consists of the gross domestic product, building footprint, road length and population, at a high geographic resolution of 10 km by 10 km.

How many rooftop solar photovoltaic projects are there in China?

There are 676 rooftop solar photovoltaic (RTSPV) pilot projects in 31 provinces in China in 2021 (Anon, 2021a). Rooftop solar photovoltaics use building roof resources to design distributed photovoltaic power stations (Tripathy et al., 2016).

What is the potential of rooftop PV in Guangzhou?

A novel systematic method for assessing the potential of urban rooftop PV is proposed. Residential areas contribute 50% of the total rooftop PV potential in Guangzhou, China. The rooftop PV potential in Guangzhou reaches 44.06–72.12 billion kWh per year. Rooftop PV reduces carbon emissions in the power sector in Guangzhou by 72.12–100%.

How big is China's photovoltaic installed capacity in 2021?

According to the International Energy Agency (IEA), additional global photovoltaic installed capacity is 134 GW in 2020, an increase of 22 percent from 2019 (Anon, 2021c). In 2021, China’s newly installed capacity of distributed PV is 29.27 GWp, accounting for 55% of the total installed capacity.

What is a high-resolution solar photovoltaic potential map of China?

A high-resolution solar photovoltaic potential map of China utilizes the open dataset and one novel neural network model. The data are stated by provinces and cities showing the regional differences. The rooftop photovoltaic generation will be closed to half of the electricity generation of China mainland in 2020.

How much power does rural residential building PV generate in China?

The total installed capacity of rural residential building PV in China is 972.9–1232.34 GWp, and the total annual average power generation is 1158.55–1467.47 TWh (Zhang et al., 2021). They evaluate the potential based on the existing statistical data. And the data resolution can only reach the municipal level.
