【摘要】 对于均衡负载固定式太阳电池方阵,不同倾角将使太阳电池方阵接受到的太阳辐射量差别很大。为使光伏方阵接受到最大的太阳辐射量,需要选择太阳电池方阵的最佳倾角。本实验对两套固定式太阳电池方阵进行了当地实况的测量,采取对比实验法和最大功率比较法寻求固定式太阳电池方阵在北纬40°附近的最佳倾角,并与根据Hay提出的天空散射各向异性模型计算的结果进行比较。结果表明,对比实验法的实验数据更接近理论值,最大偏差不超过1.5%。通过对太阳电池方阵每天输出功率的研究,为长期进行太阳能光伏发电技术的研究做一些实验探索。更多还原

【Abstract】 For even load,different tilt angle will change the amount of solar energy received by the surface of the fixed solar cell panel largely.One of the best ways to collect maximum daily energy is to choose the optimum tilt angle.Two sets of fixed solar cell panels in the region were researched by "correlation method" and "maximum power method" at the optimum tilt angle around the 40 of the north latitude.The results were compared with the calculation according to Hay’s anisotropic model of the sky diffuse radiation.Experiments show that the results of correlation method agree with those from Hay with a deviation of 1.5%.On the research of everyday output power of solar cell panel,experimental explore for serious research of photovoltaic power technique can be carried on.更多还原
