Design of Solar Street Light System Based on the Maximum Power Point Tracking and Energy Output Coordination Strategy

Abstract

The paper presents a design of solar street lamp system based on the maximum power point tracking and energy output coordination strategy. It uses chip CC2530F256 which carries with the ADC sampling output voltage and current of the solar cell to adjust the PWM duty cycle and achieve maximum power point tracking. Besides, it uses the information of the switch of ZigBee wireless network and streetlight node battery voltage to adjust the output power of the battery, thus, achieving the reasonable control of street lighting brightness. By using a chip optimized for energy inputs and outputs, the program realized simple structure and strong practical.
