The presence of green roofs reduced energy consumption by about 0.1%, while photovoltaic systems could generate 26 megawatt-hours annually, with a payback period of 6.5 to 7.5 years. Office buildings present significant potential for the installation of solar photovoltaic roofs.
While the cities have a significant share of energy consumption, they can also be considered high-potential energy producers. So, an effective solution for urban energy management to solve urban energy requirements, as well as environmental issues, is the use of rooftop solar photovoltaics .
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.
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.
A comprehensive analysis of research on solar PV roofs reveals that integrating PV components with building elements (roofs, sunshades, and louvers) is a common form in practical applications. The design challenge lies in finding a balance between the original functionality of the components and the added photovoltaic performance.
