摘要
提出一种间歇性优化调节的固定式太阳电池板最佳安装倾角的计算方法。在研究直接太阳辐射、散射辐射和地面反射辐射量的变化情况和太阳电池板光电转换关系的基础上，导出固定式安装的太阳电池板聚光能量瞬时值的计算模型。通过对倾斜面上瞬时辐射量在调整周期内的连续积分，获得在年能量收益最大化下的按月、季、半年进行调整以及全年固定式太阳电池板的最佳安装倾角。仿真计算表明，与水平安装的太阳电池板电池板相比，在不同地区按冬、夏半年期进行最佳倾角调整的太阳电池板聚光能量可增加23．8％～29．6％，有较好的综合效益。
This paper presents a method of calculating the optimization tilt angle of intermittent adjusted PV panels. Variation trends of photoelectric conversion at different direct radiation, diffuse radiation and terrain reflecting radiation were studied. Furthermore, a model of instantaneous photoelectric energy calculation of fixed PV panels was established. It could calculate the optimum tilt angles of PV panels adjusted monthly, quarterly, half yearly and yearly which make annual energy maximum by continuous integration. The result shows, relative to horizontal mounting, adjusting PV panels every half year increases the energy collection by 23.8%-29.6%. The adjustment has better comprehensive benefits.
