摘要： 随着光伏行业的发展， 分布式光伏的建设技术趋于完善， 中国近几年分布式光伏的安装多为户用型。以甘肃
省金昌市永昌县朱王堡镇居民房屋屋顶安装分布式光伏发电站为例进行研究， 根据项目所在地的光照条件和所搭设光伏
组件的建筑物屋顶条件， 设计了最佳倾角式安装系统， 并对其进行经济技术评估， 对比发电量和系统回收期确定系统的
可行性， 为分布式光伏发电设计提供一些参考。

Abstract: With the development of the photovoltaic industry, the construction technology of distributed photovoltaic tends to be
improved. In recent years, the installation of distributed photovoltaic is mostly household type. This paper studied the installation
of distributed photovoltaic power station on the roof of residential houses in Zhuwangbao Town, Yongchang County, Jinchang City,
Gansu Province. According to the lighting conditions of the project site and the roof conditions of the buildings where the
photovoltaic modules were installed, the optimal inclined installation system was designed, and its economic and technical
evaluation was carried out. The feasibility of the system was determined by comparing the power generation and the system
recovery period, which provides some reference for the development of distributed photovoltaic power generation design.
Key words: photovoltaic power generation; grid-connected photovoltaic; optimal economic analysis; on-grid subsidies
