摘要
光伏阵列的最佳安装角度是充分利用太阳能发电的有效手段之一,最佳安装角度大多依据当地夏至日的太阳高度角来确定,较少考虑当地区域气候条件的影响。本文基于天文学基础推导出光伏阵列的辐射度计算公式,结合当地的周期气候特征,通过数据拟合的方法对光伏阵列的安装角度进行优化。实验结果表明:桂林理工大学分布式光伏发电站的最佳方位角为南偏西11. 3°,最佳倾斜角为27. 5°,此时光伏发电效能最高。
The optimal installation angle of PV arrays was one of the effective means to make full use of solar power.The best installation angle was based on the sun altitude angle of the local summer solstice,and the effect of the local regional climatic conditions on the optimal installation angle of PV array was less taken into account.The installation angle of PV array was optimized by data fitting method.Based on the astronomical basis,a formula for calculating the radiation of photovoltaic arrays was introduced by combining with the local periodic climatic characteristics.The experimental results show that the optimum azimuth angle of the distributed PV power station in Guilin is 11.3°and the best tilt angle is 27.5°.At this time the photovoltaic power generation is the highest.
