研究目的
To propose a spatial photovoltaic (PV) potential evaluation method based on the combination of aerial photogrammetry and Geographic Information System (GIS) for PV potential evaluation of built environment (BE), applicable to not only building roofs but also built environments such as carpark.
研究成果
The method combining photogrammetry and GIS provides an accurate geometrical model and comprehensive analysis of the PV potential in BE with a much lower cost compared with LiDAR-based method. It is suitable for evaluating the PV potential of BEs including carparks, corridors, reservoirs, roads, and other horizontal planes. The method has been successfully applied to evaluate the PV potential of a carpark and rooftop in Singapore, demonstrating its feasibility and effectiveness.
研究不足
The method is only used to evaluate BEAPV potential on horizontal plane and does not cover the calculation of the PV application potential on facades. Additionally, a small UAV can directly obtain the geographical information of an area with a radius of less than 500m, limiting its application to larger scales without further development.
1：Experimental Design and Method Selection:
The method involves processing images captured by UAV to establish a point cloud model of the studied field, which is then imported into GIS for sunlight analysis to estimate the available area for PV installation after offsetting the identified borders of the urban and ecological infrastructures. The PV potential is determined based on the installation configurations of PV modules.
2：Sample Selection and Data Sources:
The study evaluates the PV potential of a carpark and a rooftop of a building in Singapore using UAV-captured images.
3：List of Experimental Equipment and Materials:
UAV DJI PHANTOM 3 Advanced equipped with a 12‐megapixel RGB camera FC300S, Photoscan software for 3D point cloud model construction, ArcGIS software for spatial analysis, and PVSYST software for PV potential simulation.
4：Experimental Procedures and Operational Workflow:
The process includes site investigation, UAV flight for image capture, 3D point cloud model construction, GIS-based sunlight analysis, and PV potential simulation using PVSYST.
5：Data Analysis Methods:
Solar radiation analysis in GIS to determine areas suitable for PV installation based on sunshine hours and solar irradiance, followed by PV potential calculation using PVSYST.
