In order to improve the efficiency of solar street lamp system, the maximum power point tracking (MPPT) method was applied to its controller. After the analysis of MPPT principle, specific methods to implement MPPT and drive Buck circuit were proposed. Also, by using AVR Studio program and Multisim and Proteus as the platform, a control system based on ATmega16 was finally built. On the basis of a simulation test that was passed, the experiment was conducted. The results show that the duty cycle of PWM waves is in accordance with the empirical value, which indicates that the solar panel charges the storage battery with maximum power, and the controller charges and discharges the battery in a scientific way.
