Design and Application of Solar Power Supply System

In order to reduce the loss of power transmission and distribution and save electricity, this paper discusses the mechanism of solar photovoltaic power generation and photovoltaic system maximum power tracking point Principle in depth and adopt disturbance observation method to realize the most power tracing and design an intelligent power supply system, whose main power is solar panels and batteries, and the backup power is city power. These power supplies are switched on different conditions. Practical application shows that: the voltage and current outputted by this intelligent power supply system are pretty good. In a word, this design realize the concept of low carbon green.
