To account for the change in the potential due to different panel efficiencies and rooftop availability, we have documented global and regional potentials for a set of rooftop scaling factors.
The unique properties of roofs, such as good sunlight incidence, good ventilation conditions, no redundant shielding, and flexible tilt angle for PV panels, are advantageous for solar energy harvesting. Accordingly, roofs present the highest efficiency potential for PV generation systems in buildings (Lin et al., 2014). However, the impact of .
In contrast, rooftop PV panels can be easily installed on residential, commercial, and industrial building rooftops, featuring the advantages of effective space utilization and cost-effectiveness, thereby reducing land requirements for utility-scale PV power plants and making rooftop-distributed PV systems a more attractive and encouraged .
The utilization factor is the proportion of a building’s rooftop space in which PV can be installed, and the utilization factors in this paper include the percentage occupancy of the PV array pitch.

6 FAQs about [Rooftop photovoltaic panel space utilization]
What percentage of buildings have rooftop PV systems?
The variations in the proportion of buildings with PVs indicate that the penetration of rooftop PV systems is different across the four regions. In Amsterdam, buildings with rooftop PV installations account for 6.59% of the total, which is the highest, followed by Fujisawa at 6.17%, Berlin at 5.17%, and Boston at 3.16%.
Do rooftop PV resources affect solar energy generation in China?
It is observed that areas with sufficient rooftop PV capacities have moderate to inferior PV efficiency (CF ≤ 0.14), while building roof resources are scare in areas with high PV efficiency (CF close to 0.20). Such spatial inconsistency between roof resources and solar resources somehow reduces the electricity generation of rooftop PVs in China.
Can a rooftop solar system be a non-viable solar plant capacity?
However, the present study was initiated by retrofitting the entire rooftop into PV panel system, which resulted in a non-viable solar plant capacity. Therefore, an optimization was done by limiting the PV panel capacity by the contract demand of each site.
Can PV power be installed on rooftops of urban buildings?
Using Guangzhou, a city in southern China, as an example, we offer four installation scenarios based on rooftop area data and research on relevant characteristics and analyze the technical and economic potential of PV power generation on the rooftops of urban buildings.
Do rooftop photovoltaic solar panels affect urban surface energy budgets?
Our study also reveals that rooftop photovoltaic solar panels significantly alter urban surface energy budgets, near-surface meteorological fields, urban boundary layer dynamics and sea breeze circulations.
Does a high-resolution global assessment of rooftop solar photovoltaics potential exist?
Yet, only limited information is available on its global potential and associated costs at a high spatiotemporal resolution. Here, we present a high-resolution global assessment of rooftop solar photovoltaics potential using big data, machine learning and geospatial analysis.
