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.
Their incorporation into building roofs remains hampered by the inherent optical and thermal properties of commercial solar cells, as well as by esthetic, economic, and social constraints. This study reviews research publications on rooftop photovoltaic systems from building to city scale.
Using Guangzhou, a city in southern China, as an example, we offer four installation scenarios based on rooftop area data and research on relevant characteristics and analyze the technical and economic potential of PV power generation on the rooftops of urban buildings.
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.
Shrestha and Raut (2020) assessed the technical, financial, and market potential of the rooftop PV system on residential buildings in three major cities of Nepal through a field survey instead of simulation, and the results showed that 35% of the city's annual electricity consumption could be covered by solar power.
