Research on energy saving and carbon reduction throughout whole life cycle of rooftop photovoltaics: A case study of a tourism and resort complex project
摘要：
建筑屋顶全年辐照度资源丰富且施工便捷,光伏技术与建筑屋顶相结合具有极佳的应用潜力。本文以淇水湾旅游度假综合体的建筑屋顶光伏系统为研究对象,建模分析其全年运行及全生命周期运行过程中的节能及减碳特性,以评估建筑屋顶光伏系统的节能降碳效果。研究结果表明:屋顶光伏系统全年累计发电量及减碳量分别为67.30万kW·h和390.3 t;随着运行年限的增长,屋顶光伏系统发电量及减碳量呈不断减少的趋势,首年发电量及减碳量分别减少2.03万kW·h和11.7 t,而后每年减少0.43万kW·h和2.4 t,全生命周期运行过程中屋顶光伏发电量累计减少11.67万kW·h。本文研究结果可为实际工程项目中的屋顶光伏系统节能减碳测算及评估提供一定参考。
Abstract：
The combination of photovoltaic technology and building roofs has excellent application potential due to the abundant annual irradiance resources of building roofs and the convenient construction. In this paper, the building rooftop photovoltaic system of Qishuiwan tourism and resort complex project is taken as the research object, and the energy saving and carbon reduction characteristics of the whole year operation and the whole life cycle operation are analysed by modeling to evaluate the energy saving and carbon reduction effects of the building rooftop photovoltaic system. The results show that the annual cumulative photovoltaic generation and carbon reduction of the rooftop photovoltaic system are 673 000 kWh and 390.3 tons, respectively. With the growth of the operation years, the photovoltaic generation and carbon reduction of the rooftop photovoltaic system show a decreasing trend. The first year, the photovoltaic generation and carbon reduction are reduced by 20 300 kWh and 11.7 tons respectively, and then reduced by 4 300 kWh and 2.4 tons every year. The cumulative reduction of rooftop photovoltaic generation during the whole life cycle operation is 116 700 kWh. This study can provide a reference for the calculation and evaluation of energy saving and carbon reduction of rooftop photovoltaic systems in practical engineering projects.
