Abstract:

This article focuses on the energy consumption of the solar tracking system and studies the impact of stepper motor's starting frequency on the efficiency of electric power generation.Optimization methods of improving the efficiency of power generation by reducing the frequency of stepper motor's starting frequency is given in theory.Matlab simulation results have shown that lower starting frequency of the stepper motor can reduce the energy consumption of the solar tracking system itself,thereby improving system efficiency of power generation.

Key words: stepper motor;solar energy tracking system;energy consumption
