Optimal design of array spacing for tracking photovoltaic devices

提出一种跟踪式光伏设备的阵列排布优化设计方法.该方法从分析影响阴影形成的要素着手,构造跟踪式光伏设备的电池面板在太阳照射下的阴影测算模型,从而推导其阴影的全年变化规律,实现跟踪式光伏设备阵列式排布的最优间距设计.实验表明,该方法给出的排布方案能保证光伏阵列在开机运动时段内不产生阴影遮挡,且排布间距最小,可有效节省建设用地.

An optimal method of array spacing design for tracking photovoltaic devices is proposed. The method analyzes factors affecting the formation of shadow, structures the calculating model of photovoltaic cell panels＇ shadow in the sunlight, and then designs a spacing measurement of the solar tracking device array through simulating experiments of finding the rules of shadow in a whole year. The experiment results show that the proposed method can minimum the photovoltaic device configuration distance by ensuring the photovoltaic panels without shelter, can effectively save area of earth in building the photovoltaic power station.
