鉴于国内能源消耗实际情况,为了使太阳能新能源更好地服务于现代化建设,笔者通过居民的电力情况和屋顶结构的研究,分析不同屋顶结构的光伏系统的安装发电和盈利能力,并对其经济效益进行了估算,表明城市坡面屋顶更适合安装光伏系统,如果采用全部电能自发自用的消费模式,其投资回收期最短,经济效益最高。笔者通过本次内容研究,以为民用光伏发电系统经济效益的研究提供一定的参考价值。
In view of the actual situation of domestic energy consumption, in order to better serve the modernization of new solar energy sources, the author analyzes the electricity generation and profitability of photovoltaic systems with different roof structures through the study of residents’ electricity conditions and roof structure, and analyzes its economy The results show that the urban slope roof is more suitable for the installation of photovoltaic systems. If all the consumption patterns of electricity are used for their own consumption, the investment recovery period is the shortest and the economic benefit is the highest. Through this content research, the author thinks that it provides a certain reference value for the research of economic benefits of civil photovoltaic power generation system.
