摘　　要：本文对中国内地各个省份农村建筑屋顶可用于太阳能光伏发电的空间资源进行了评估,进一步计算其发电能力,并对其经济效益进行综合分析。研究结果表明:中国内地农村地区目前拥有超过64亿m^(2)的建筑屋顶面积可以用来安装光伏组件,其年发电量1158.55~1467.47 TWh,最多可达到2019年农村用电量的1.55倍;同时,结合能源效益和经济效益,可以将中国内地分为三类资源区,一类资源区回本时间短,二类资源区回本时间稍长但发电总量大,三类资源区回本时间最长且发电量少,对比发现一、二类资源区农村适合建设屋顶分布式光伏系统。This paper evaluates the spatial resources available for solar photovoltaic power generation on the rooftops of rural buildings in each province of China's Mainland,further calculates their power generation capacity,and provides comprehensive analysis of their economic benefits.The research results show that rural areas in China's Mainland currently have more than 6.4 billion m^(2) of building rooftop area that can be used to install PV modules,with an annual power generation capacity of 1158.55~1467.47TWh,up to 1.55 times the rural electricity consumption in 2019.At the same time,combining energy efficiency and economic benefits,China's mainland can be divided into three types of resource areas,the first class resource area with a short payback time,the second class resource area with slightly longer payback time but more power generation,and the third class resource area with the longest payback time and less power generation,which indicates that the first and second class resource rural areas are suitable for the construction of rooftop distributed photovoltaic systems.
