摘要
基于太阳能辐射强度模型,推导出光伏阵列在任意地区朝向跟踪和固定式接收的总辐射日曝辐量计算方法,进而计算出总辐射年曝辐量,获得光伏阵列朝向跟踪的能量年增加率。最后以北京地区为例,计算出朝向跟踪比固定式(朝南最佳倾角时)年接收能量提高34%。
Based on the (sunny) model of solar radiant intensity, the mathematical formulas for the daily solar ra- diation received by photovoltaie cells toward tracking and fixed ones at any region was deduced . Then the yearly solar radiation received, and obtained energy efficiency increased by photovoltaic cells toward tracking can be cal- culated. Finally, taking Beijing area as an example, we concluded that sun tracking system gains 34% more energy compared with fixed ones.
