【摘要】 以某钢厂屋顶光伏项目为例，分析了站址太阳能资源数据，通过对钢厂内复杂屋顶和建筑物群的同尺寸3D建模，准确分析了各建筑物屋顶的阴影遮挡区域，优化了光伏组件的布置。最后根据PVsyst软件对屋顶光伏系统的效率和发电量进行了仿真。更多还原

【Abstract】 Taking the roof PV project of a steel plant as an example, this paper first analyzes the solar energy resource data of the station site. Through the same size 3 D modeling of the complex roof and building group in the steel plant, the shadow shielding area of the roof of each building is accurately analyzed, and the layout of photovoltaic modules is optimized. Finally, the system efficiency and power generation of roof photovoltaic system are simulated according to PVsyst software.更多还原
