中文摘要
摘要 准确且详细地估算屋顶光伏（PV）安装潜力对于指导屋顶光伏部署策略具有重要意义，有助于加速实现碳中和目标。屋顶光伏安装系数是估算屋顶可安装光伏面积的关键参数。现有方法通常通过在未安装光伏系统的屋顶上设计假设布局来估算该系数。然而，此类方法可能与实际安装后的观测值存在偏差。本研究提出一种基于大量已安装光伏系统建筑的实际数据来确定屋顶光伏安装系数的方法。采用无人机（UAV）航拍技术快速、全面地获取屋顶光伏安装信息，包括光伏面积与屋顶面积之比、建筑类型、屋顶类型以及安装方式。本文收集并分析了中国三个城市共279栋建筑的屋顶光伏安装数据，针对六类建筑类型推导出相应的屋顶光伏安装系数，可用于估算城市范围内的屋顶光伏安装潜力。以武汉市中心城区为例进行案例研究，计算了不同功能区的光伏安装潜力以及单体建筑的平均安装潜力。结果表明，武汉市各类建筑的屋顶光伏安装系数介于0.26至0.50之间，全市平均值为0.32，显著低于以往大多数未考虑实际安装数据的研究所报告的数值。武汉市中心城区的屋顶光伏可安装面积潜力约为38 km²，最大年发电潜力约为9308 GWh。根据武汉市2024年的总用电量，该发电潜力可满足全市总电力需求的18.9%。
English Abstract
Abstract An accurate and detailed estimation of rooftop photovoltaic (PV) installation potential is important for guiding rooftop PV deployment strategies, thereby accelerating progress toward carbon neutrality. The rooftop PV installation coefficient is a key parameter for estimating the rooftop installable PV areas. Existing methods typically estimate the rooftop PV installation coefficient by designing hypothetical layouts on rooftops without installed PV systems. However, such approaches may lead to discrepancies from the actual installation coefficients observed after installation. This study proposes a method for determining rooftop PV installation coefficients based on real-world data collected from a large number of buildings with existing PV installations. Unmanned aerial vehicle (UAV) photography is employed to rapidly and comprehensively capture rooftop PV installation information, including the ratio of PV to rooftop area, building type, roof type, and installation method. PV installation data from 279 buildings across three cities in China have been collected and analyzed. Rooftop PV installation coefficients were derived for six building types, which can be applied to estimate the city-wide rooftop PV installation potential. Taking Wuhan central urban area as a case study, the PV installation potential of different functional zones and the average installation potential of individual buildings have been calculated. The results indicate that the rooftop PV installation coefficients for various building types in Wuhan range from 0.26 to 0.50, with an overall citywide average of 0.32. These values are significantly lower than those reported in most previous studies that did not incorporate actual installation data. The rooftop PV installation area potential in Wuhan central urban is estimated at 38 km 2 , with a maximum power generation potential of approximately 9308 GWh/year. Based on Wuhan's total electricity consumption in 2024, this could meet 18.9 % of the city's total electricity demand
