In order to improve the efficiency of photovoltaic power generation,the biaxial solar tracking device was designed with ATmage16 microcontroller as the control chip,on the basis of choosing high accuracy sun location al-gorithm,by using photosensitive resistance eye tracking Angle fine-tuning. And the tracking number and tracking intervals at different time were optimized through the analysis of relationship between energy consumption and pro-duction capacity during the device runtime. Theoretical analysis and experimental results show that the scheme can accurately track the sun,and can effectively improve the utilization rate of solar energy.
