Design of control system for solar panel automatic tracking

In order to use solar-powered,a system that solar panel can automatic track the sun is produced.The system use combined method of solar movement tracking and maximum power point seeking,it controls solar energy conversion utilization device automatically and rotated it to aim at the sun,and it can raise the solar energy absorption rate.In the system,single-chip microcomputer is used as the controller,small solar battery is used as sensor,and stepper motor is used as actuating mechanism.The system has some practical value for devices which rely on the solar energy.
