摘　　要：根据太阳能电池方阵斜面太阳辐射量计算模型,计算得出了广州市不同年份太阳能电池方阵斜面年总辐射量随倾角的变化关系,并求得历史不同年份的方阵最佳倾角。以半年、季度、月为时间间隔,对太阳能电池方阵南北向进行了二步、四步、十二步的不连续跟踪研究,得出不同跟踪时间段内的斜面最佳倾角及相应的辐射增益,据此计算出不同跟踪方式的全年总辐射增益,分析了不同安装方式对提高太阳能电池方阵斜面辐射量的效果。Depending on solar radiation calculation mode for inclined PV panel, yearly global radiation on surfaces tilt at different angles were calculated on several years. Historicaly change was obtained on optimum tilt angle. Yearly north-south step tracking for PV panels were researched by two, four, twelve steps according to different intervals like half year, season and month. Optimum tilt angels and corresponding radiation plus for different tracking time intervals and the whole year were calculated. To maximize yealy global radiation, the effects of different install modes were analyzed.
