Photovoltaic (PV) power generation is booming in rural areas, not only to meet the energy needs of local farmers but also to provide additional power to urban areas.
1. Introduction Rooftop photovoltaic power generation is installed on the roofs of buildings and directly connected to a low-voltage distribution network; it has the advantages of proximity to the user side, local consumption, and reduction in transmission costs. China's existing residential building area is more than 700 billion m 2.
Distributed rooftop photovoltaic (PV) cells, in comparison to hydropower and wind generation, use only space and radiation resources and are the least restricted by geography and climate, making them a significant choice for communities looking to create green electricity.
Yet, only limited information is available on its global potential and associated costs at a high spatiotemporal resolution. Here, we present a high-resolution global assessment of rooftop solar photovoltaics potential using big data, machine learning and geospatial analysis.
Gernaat et al. (2020) estimated that the global suitable roof area for PV generation was 36 billion square meters. This represents a potential of 8.3 PWh/y, which is equivalent to 150% of the global residential electricity demand in 2015. This demonstrates the potential of replacing traditional electricity sources with rooftop PVs.
Particularly in the residential sector, rooftop PV systems have seen significant adoption as decentralized electricity generators 3. Projections from the International Energy Agency (IEA) indicate that rooftop PV capacity is expected to reach 143 GWp by 2024, a substantial increase from 58 GWp in 2018 4.
The evaluation of rooftop PV utilization potential is mainly divided into three parts: geographical potential, physical potential, and technical potential. Figure 1 illustrates the framework of the proposed method. Figure 1. Potential evaluation flow chart of rooftop PV. 3. Methodology 3.1.
