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 photovoltaics alone cannot meet the demand for clean electricity. All regions should develop multiple types of new energy sources according to local conditions, in order to achieve clean replacement and sustainable development of traditional energy sources as soon as possible. All authors contributed to the study conception and design.
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.
The United Kingdom and United States are among the most costly countries, costing $251 and $238 per megawatt-hour. "For the first time, we can analyse the spatial and temporal characteristics of global rooftop photovoltaics with improved accuracy using a combination of big data, machine learning and GIS.
