摘要
以单位面积全年接收的太阳能总辐射量最大为目标,根据某市典型气象年的逐时气象数据,建立随光照辐射强度变化的光伏电池板最佳铺设倾角动态优化模型。模型仿真计算结果表明,同一地点光照辐射强度的差异对最优倾角有显著影响,与同月固定最优倾角相比,采用动态优化的日固定倾角,光伏电池单位面积全年接收的太阳总辐射量增加57.13%。
The model of PV panel optimum tilt angle with the change of radiation intensity is built based on a city＇s hourly meteorological data in typical meteorological year, in an attempt to receive the maximum annual amount of radiation per unit area. Simulation results show that the optimum tilt angle of the corresponding period has a re- markable influence on the solar radiation in the same district. Compared with the monthly fixed optimum tilt angle, the daily fixed tilt angle can receive 57.13% more of solar radiation.
