6 FAQs about [Rooftop solar photovoltaic power generation mapping]

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.

How accurate is the spatial distribution of rooftop PV power generation potential?

By combining the above results and setting the solar radiation parameters and PV system efficiency, we can obtain the spatial distribution of the rooftop PV power generation potential in rural areas. This method is applied in northern China on a village and a town scale, and the overall accuracy of the revised U-Net model can reach over 92%.

Is rooftop PV the future of solar energy?

In 2020, 127 GW of new PV power generation were installed globally, bringing the cumulative installed capacity to 707 GW. Among the available technologies, rooftop PV is the inevitable trend of the coming decades. Understanding rooftop PV potential is critical for the development and utilization of solar energy.

What is the maximum rooftop solar PV power generation in village a?

When we only considered the PI method, the maximum rooftop solar PV power generation of a single building in Village A was over 40,000 kWh, with an average of 16,900 kWh. Fig. 19. Rural rooftop solar photovoltaic (PV) potential distribution of each roof in Village A; OTI: optimal tilt installation, PI: parallel installation.

What is solar rooftop potential?

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.

How can we estimate rooftop photovoltaic electricity potential in different regions?

Some researchers have studied estimating the PV potential in different regions using different methods. F.M. Kouhestani et al. used a multi-criteria approach based on geo-graphic information systems (GIS) and light detection and ranging (LiDAR) to estimate rooftop photovoltaic electricity potential of buildings in the city of Lethbridge [ 1 ].
