Optimal algorithm of fixed PV panel optimum tilt angle

针对安装固定式的光伏电池板建立瞬时辐射量模型,并给出固定安装时的年最佳设计倾角计算方法。以步长为0.01°逐一计算不同安装倾角下的年辐射量,利用设定角度范围进行循环穷举法寻优的方式计算安装固定式的光伏太阳电池板的最佳倾角。以部分城市为例计算固定安装时的年最佳设计倾角,另外给出了以北京为例一个城市的每月最佳倾角及平均日光辐射总量。结果分析表明,本算法具有一定的实用参考价值。

Annual optimum design tilt angle algorithm in fixed installation was given upon assemble fixed PV panel establishing instantaneous radiation model. At 0.01° step size, the annual radiation volumes at different assemble tilt angles were calculated respectively. Angle range setting was utilized to conduct circulation exhaustive method for searching optimum in the calculation of optimum title angle of assemble fixed PV panel. Some cities were taken as examples for calculating the annual optimum design tilt angle in fixed assembling. Also, Beijing was taken as an example where optimum tilt angles at each month and average solar radiation total volume were given. Results and analysis show that this algorithm possesses some practical reference value.
