Customer ServiceFig. 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.
Overall, the national rooftop areas are substantial across all scenarios, ranging from 2100 to 4500 km2. The applied methods and scenarios provide a straightforward way to reveal the spatiotemporal variability and define realistic ranges of the solar photovoltaic potential without requiring detailed information about each building.
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.
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.
The rooftop PV potential was estimated to total 22,551 GWh. Therefore, the performance of the rooftop PV potential estimation method performs well. In this study, the solar radiation data are the global surface solar radiation (3 h, 10 km) which is more suitable for large-scale photovoltaic potential assessment.
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.
