Author to whom correspondence should be addressed. Urban expansion and fossil fuel dependence have led to energy and environmental concerns, highlighting the need for sustainable solutions. Rooftop photovoltaic (RPV) systems offer a viable solution for urban energy transition by utilizing idle rooftop space and meeting decentralized energy needs.
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.
Rooftop photovoltaic (RPV) systems can be deployed on various buildings, contributing considerable power generation potential through intensive small-scale installations . Additionally, RPV systems can be directly connected to energy consumers, effectively accommodating the increasingly decentralized energy demand .
In built-up areas, ground space for further development is limited due to high-intensity land use, making building rooftops ideal for utilizing solar energy resources . Rooftop photovoltaic (RPV) systems can be deployed on various buildings, contributing considerable power generation potential through intensive small-scale installations .
Rooftop photovoltaic (RPV), initially a niche solution 8, may also offer a global-scale opportunity to reduce fossil fuel reliance 9. Previous studies have shown that the carbon mitigation potential of RPVs in China is up to 4 gigatonnes (Gt), accounting for 70% of the country’s emissions from the electricity and heat sector 10.
