太阳能光伏电池板倾角优化研究

对于固定式太阳电池方阵,不同倾角直接影响到太阳能电池方阵接收到的太阳辐射量。为使光伏方阵效率最大化,需要对太阳能光伏电板的倾角进行设计及优化,选择太阳电池方阵的最佳倾角。在前人的简化模型基础上提出更精确的太阳能光伏电池板倾角优化算法,并在使用《天文算法》中的复杂算法得出的高精度太阳位置的基础上自建模型加入晴雨时长系数修正,通过对直接辐射时长的比较提高算法精度。实践证明,经过优化的方法为太阳能设备效率优化提高了精确度。

Study on the Optimizing of the Solar Energy Photovoltaic Panel Angle

For a fixed solar cell array, different angle directly affects the volume of solar radiation received by the solar cell array. In order to maximize its efficiency, the angle of the solar cell array needs to be designed and optimized to select the best angle for it. This paper provides a more accurate calculation method than previous simple mode. It uses the complicated calculation of astronomy arithmetic to get the more accurate position of the sun, and introduced the parameters modification of the duration of rain or fine days, thus greatly improved the accuracy of the calculation. Evidence of experiment shows that this optimizes method can improve the accuracy and efficiency of solar energy equipment.
