摘要
提出一种针对光伏发电占地成本日益增加的新型占地集约化光伏阵列布置方式。以太阳能资源丰富的珠海地区为例,根据晴好天气条件下的太阳辐射参数,选择合适的倾角,通过建立倾斜面上瞬时光辐射量数学模型,推导出新型光伏阵列朝东西对称放置与现有朝正南放置时的年太阳辐射量数学模型,建立对比方案,可以看出新型光伏方阵组件在朝东西对称时单位占地面积所接受的辐射量更多,月平均电能输出变化更加平稳。
mode of land increasing This article proposes a new layout intensive photovohaic arrays to prevent land use cost of photovohaic power generation, taking Zhuhai district, which enjoys abundant solar energy resources, as an example, based on solar radiation parameters in the condition of sunny weather and in properly dip angle. It is completed by building instantaneous solar radiation mathematical model on inclined surface to deduce the annual solar radiation mathematical model of the new photovohaic arrays when they are of east-west symmetry and when they are in current Southward placement. The comparison plan is established to reach the conclusion that the new photovohaic arrays of unit land area receive more solar radiation in symmetrical placement and the range of monthly average power output stays steadier.
