摘要： 通过对上海市居民用电情况和居民建筑屋顶结构形式的调研，分析了不同屋顶结构安装光伏系统的发电量和
收益情况，及不同用电方式的经济效益估算。结果表明，与平屋顶相比，坡面的别墅屋顶更适合安装光伏系统，方便在
城市推广和操作实施，若同时采用全部自发自用的消费模式，经济回收期最短，收益更大。

Abstract: By the research on residential electricity situation and residential building roof structure in Shanghai City, this paper
analyzed generating capacity and earnings of installed photovoltaic system in different roof structures and economic benefit
estimation of different electricity using way. The result showed that villa roof with slope surface was more suitable for the
installation of photovoltaic system compared with the flat roof, which is convenient to promote and implement in city. If
spontaneous private consumption patterns were applied, the payback period is the shortest and benefits were more.

Key words: residential electricity; household photovoltaic system; economic benefits
