摘　　要：提高光伏阵列电站的发电量和工作效率,系统实行向阳跟踪技术是关键。研制了一种新型光方位传感器,由两个布置成一定角度感光面朝外硅光电池组成,并进行实验。实验表明长时间跟踪引发的能量损失得到降低,光伏阵列电站能量转换得到改善,控制和机械装置简化,成本低应用推广方便。It is of crucial importance for PV power generation systems to work at efficiency conditions and to maximum the electrical power output by using a sun tracking system.A novel approach using two photocells placed in a wedge shaped form as a new tracking sensor is studied and tested.The power loss caused by over long time tracking can be reduced,and the energy conversion efficiency of photovoltaic can be improved.The control and mechanism is very simple,which can reduce the cost and make the implementation easily.
