A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity -generating solar panels mounted on the rooftop of a residential or commercial building or structure.
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.
Urban building rooftops provide promising locations for solar photovoltaic installations and can contribute effectively to make nearly net-zero energy buildings . Rooftop solar photovoltaics can be considered an effective solution for urban energy management to solve urban energy requirements and environmental problems .
The roof-mounted solar PV is installed at the optimum angle for each latitude and is sun-facing and shade-free to generate maximum electricity output. The building rooftops are flat in design leading to the utilization of the entire rooftop for the installation of solar panels.
The building rooftop presents a wealth of spatial opportunities for promoting the utilization and conservation of solar energy. The installation of photovoltaic panels on rooftops is a feasible and convenient method for integrating renewable energy sources into 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.
