Solar potential of rooftops in Cáceres city, Spain

Climate change is one of the challenges our society has to deal with nowadays. Photovoltaic is one of the main renewable energies and it is gaining ground all around the world. The prediction of solar radiation is crucial for this kind of energy. The aim of this work is to produce a solar potential map of rooftops the city of Cáceres (Spain) providing an overview of the employed methodology. The estimation of global radiation is based on LiDAR data of high density. Historical radiation records have been also employed to define the calculation parameters. The representation of the estimated global radiation on each building provides a wide range of new possibilities in the use of renewable energies and changes the conception of rooftops to a potential source of photovoltaic energy.

气候变化是当今人类社会亟需应对的重大挑战之一。光伏（Photovoltaic）作为核心可再生能源之一，目前在全球范围内得到愈发广泛的应用。太阳能辐射预测对这类能源的开发利用具有关键意义。本研究旨在绘制西班牙卡塞雷斯（Cáceres）城市屋顶的太阳能潜力分布图，并对所采用的研究方法进行全面概述。全球辐射量的估算基于高密度激光雷达（LiDAR）数据，同时借助历史辐射观测数据确定计算参数。将各建筑的估算全球辐射量可视化后，可为可再生能源的开发利用带来诸多全新可能，同时重塑了人们对屋顶的认知，将其视为潜在的光伏能源开发载体。
