UFC911B110 3BHE037864R0110 of photovoltaic (PV) power generation technology has been intensively researched and promoted in foreign countries, and our country has basically matured technologically and has entered the stage of promotion and application [1]. However, solar energy has the problems of low density, intermittency, and constant changes in the direction and intensity of light over time, which puts forward higher requirements for solar energy collection and utilisation devices. Many current solar panel arrays are basically fixed, which cannot make full use of solar energy resources and have low power generation efficiency.

UFC911B110 3BHE037864R0110 can always keep the solar panels and light perpendicular to maximise the reception of solar energy, then it can make full use of the abundant solar energy resources. According to experiments, in solar power generation, under the same conditions, the use of auto-tracking power generation equipment is required to increase power generation by about 35% compared to fixed power generation equipment. Therefore, the design and development of a control system that can automatically track solar light is a very valuable research topic.
