Evaluation of Photovoltaic Utilization Potential of Urban Building Roof

The evaluation method and step of photovoltaic utilization potential of urban buildings roof are put forward based on a three-step method: Firstly, the roof of the building was identified according to the improved SegNeXt and GIS, and then the roof was reduced according to the provisions of the national Code for Design of Photovoltaic Power Station GB50797-2012. Finally, the photovoltaic utilization potential of the roof was calculated based on this. This method has low cost, high precision and is suitable for large-scale urban buildings.
