摘要
提出一种针对任意朝向安装的固定式光伏电池板计算最佳安装倾角的计算方法。通过建立倾斜面上瞬时光辐射量数学模型,推导出年聚光量的计算方法。以步长为0.2°逐一计算不同安装倾角下的年辐射量,寻优比较得到任意朝向安装的固定式光伏电池板的最佳安装倾角。以太阳能资源丰富的青海省部分地区为例,根据晴好天气条件下的太阳辐射参数,计算了不同坡度、不同朝向安装的光伏电池板的年聚光量。
A method of calculating the optimum tilt angle of fixed PV panels for arbitrary direction installation was presented. By establishing a model of instantaneous photoelectric energy on tilted surface, a method of annual collection energy was deduced. At 0.2° step size, the annual radiation energy at different assembled tilt angles were calculated respectively, optimum title angle of fixed PV panels for arbitrary direction installation was obtained by comparing with optimization. The regions of Qinghai province rich in solar resources were taken as an example, annual collection energy of PV panels installed by different slope and different orientation were calculated according to the data of solar radiation in sunny days.
