1. Introduction Rooftop photovoltaic power generation is installed on the roofs of buildings and directly connected to a low-voltage distribution network; it has the advantages of proximity to the user side, local consumption, and reduction in transmission costs. China’s existing residential building area is more than 700 billion m 2.
The results show that current global rooftop potential is 1.5 times the residential electricity demand. The market penetration of rooftop solar PV is much more dependent on socio-economic and policy factors than on the biophysical potential. Several aspects require further discussion.
The research and development of a scientific and feasible system for evaluating the potential of rooftop solar distributed photovoltaic utilization will help to better utilize solar energy, solve the urban energy crisis, and reduce the dependence of buildings on mineral energy.
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.
Rooftop photovoltaic has been important in the past and will likely remain so in the future. We used the IMAGE model to compare two scenarios-one in which we simulated the availability of rooftop photovoltaic and one in which we did not.

Solar rooftop potential for the entire country is the number of rooftops that would be suitable for solar power, depending on size, shading, direction, and location. Rooftop potential is not equivalent to the economic or market potential for rooftop solar—it doesn''t consider availability or cost. Rather, it is the upper limit of solar deployment on rooftops across the country.
