摘　　要：通过RETScreen4软件仿真数据和实测数据对比,简要介绍光伏组件倾角、方位角、阴影和污物等因素对并网光伏系统发电量的影响,得出结论:光伏组件倾角对发电量的影响远大于方位角的影响;应结合场地条件合理选择组件安装方位角和倾角;尽量避免周围建筑和设施对组件的遮挡。This paper briefly introduces the influence of dip angles, azimuth angles, shadow and pollutants in photovoltaic module on the generating capacity of grid-connected photovoltaic system, and concludes that the influence of dip angles in PV module is greater than that of azimuth angles, and that the azimuth angle and dip angle for installation of PV module shall be selected reasonably in combination with on-site conditions to avoid the overlapping of module by surrounding buildings and facilities as much as possible.
