Fig. 12 shows the annual solar PV potential of rooftops and facades with different orientations, as well as the total amount of these potentials in the village. The total solar PV potential (T_R + T_F) is 1.9 GWh, among which the rooftops and façades account for 71.7% (1.4 GWh) and 28.3% (0.5 GWh), respectively.
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.
South- and north-facing rooftops and south- and west-facing facades are the highest ranks. The former two account for more than 70% of the total rooftop solar PV potential while the latter two contribute over 90% of the façade solar PV potential.
The results showed that rural rooftops facing south and north, and facades facing south and west, have the highest PV potential ranks. North-facing rooftops with a slope of 30° represent 32.7% of the total rooftop solar PV potential, therefore, they should not be neglected in future evaluations.
Based on a DeepLab v3 algorithm, Zhong et al. extracted city-scale roofs from google earth satellite images, and then estimated the rooftop PV potential for urban and rural areas using a physical PV model. The most crucial feature of this approach is the low cost of data acquisition.
North-facing rooftops with a slope of 30° represent 32.7% of the total rooftop solar PV potential, therefore, they should not be neglected in future evaluations. The proposed approach is cost-effective and valid for accurately assessing micro- and macro-scale rural solar PV potential that can facilitate rural renewable energy penetration. 1.
