Photovoltaic Automatic Tracing System

With the resources being used continuously, the energy structure based on conventional energy resources will not more and more adapt to requirement of sustainable development. So accelerating the exploitation and utilization of renewable resources that solar energy is principle part has been our common ideas. Using the clean solar light energy, the technology of photovoltaic generating electricity is very promising. The thesis presents a new optimal design method.This thesis mainly describes a method of single axis solar energy automatic tracing system. Every part of this automatic system and its function are analyzed in detail. A set of automatic tracing device is designed with Microcontroller C8051F310. This system has four characteristics, such as smaller cubage, lower power, lower cost, more robust despite strong interfere . Moreover, some programs are designed to debug the designed system, to test its reliability and the results of test are given.Single axis solar energy automatic tracing system follows the orientation angle with Microcontroller system.Height angle can be adjusted by hand ,it makes the solar cell keep the higher electricity power.The single axis solar energy automatic tracing system is compared with the double axis solar energy automatic tracing system,we testify its feasibility in theory . Double axis solar energy automatic tracing system consists of solar transducer,this device gets rid of transducer,it uses power of solar cell as angle regulation basis to realize controlling.In a pasturing area of our country, they use photovoltaic system without tracing device, solar electricity efficiency is lower, the tracing system we designed has better tracing effect ,its configuration is simple, the capability price ratio is high, it is adapt to be use there in particular.
