摘　　要：在Klien和Theilacker所提出的倾斜面上月平均太阳辐照量的计算模型基础上,提出了一种使用逐步查找法确定太阳能阵列最佳倾角的新方法,并利用计算机编程语言C#完成了算法的软件实现。利用该方法对我国部分地区全年最佳倾角及其各月平均日辐射量进行了计算与分析。通过与前人研究结果对比表明,该方法具有良好的适用性,为其在光伏系统设计中的工程应用提供了可能。A new method using step by step search function to determine the optimum tilted angle of solar PV arrays was put up. This method bases on Klien and Theilacker＇ s model about calculating the monthly mean daily tilted surface solar radiation. A software implementation of the algorithm was completed with computer programming language C # to calculate and analyze data of yearly optimum tilted angle and its mean daily solar radiation for every month in some regions of China. By compare with previous studies, the results show that it has a good applicability and can work well when being applied in PV projects.
