Can 3D building models be used to assess rural solar PV potential?

The significance of this study is that the proposed approach alleviates the challenges in accurately assessing rural solar PV potential posed by the lack of 3D building models. The determined PV potential ranks for rooftops and façades with different orientations provide a reliable basis for PV planning in rural areas.

Are roof-mounted solar PV systems a viable energy source for rural microgrids?

In rural areas, roof-mounted solar PV systems are among the main energy system development targets, and the spatial distribution information of PV power generation is crucial for the construction of rural microgrids.

Can GIS data accurately estimate solar PV potential in rural areas?

In this study, we proposed a novel approach that for the first time constructed rural 3D building models from publicly available GIS data and accurately estimated the rooftop-and-façade solar PV potential in rural areas. We used Google Earth satellite images to create a rural building dataset, which was then used to train an RF model.

Can a 3D model predict solar PV potential of rural rooftops & facades?

To address this issue, we proposed a novel approach, which for the first time constructs rural 3D building models from publicly available satellite images and vector maps. Based on these models, it precisely evaluates the solar PV potential of rural rooftops and facades.

How can solar PV be used in rural areas?

The rural annual electricity demand can be satisfied by installing PV modules on all rooftops or facades. Rooftops facing south and north and facades facing south and west have the highest PV potential ranks. They account for more than 80% of the rooftop solar PV potential and over 90% of the facade solar PV potential respectively.

Can a 3D building model accurately estimate solar PV potential?

Characterization of solar photovoltaic (PV) potential is crucial for promoting renewable energy in rural areas, where there are a large number of roofs and facades ideal for PV module installation. However, accurately estimating solar PV potential on three-dimensional (3D) rural surfaces has been challenging due to the lack of 3D building models.
