摘　　要：目前山地光伏电站工程中,非正南向坡面上的固定式组件往往采取和正南向坡面统一的安装参数,这通常无法实现光伏资源的最佳利用。针对非正南向坡面光伏资源开发需要,建立山地坡面组件辐照度计算模型,并分析山体遮挡对组件接收辐照的影响,提出一种坡面安装组件的最佳朝向角和倾角的优化计算方法。最后结合工程案例论证所提方法的有效性。For photovoltaic power station on mountainous area,installation parameters of fixed photovoltaic modules on non-south-facing slope are often the same with south-facing slope’s,which cannot achieve the full utilization of photovoltaic resources. In order to develop solar resources on non-south-facing slope,a solar radiation model for photovoltaic module installed in mountain slope is established,and a novel influence analysis method for self and cast shadows produced by the orography is designed. Moreover,an optimal calculating method of photovoltaic modules installing tilt and orientation angles is proposed. Finally,an engineering case vilifies the efficiency of the method proposed.
