Design of Automatic Sunlight Tracking Solar Panel System Based on Single Chip Microcomputer

Solar energy is a kind of renewable energy, it‘s abundant, clean and environmental protection. In the current theme that calls for saving energy and reducing pollution, it’s undoubtedly of great significance to make full use of solar energy. In order to effectively use solar energy, we developed an automatic sunlight tracking solar panel system based on single chip microcomputer. We use MC9S12XS128 single chip microcomputer as the main control chip, and acquire signal with the sensor composed of photoconductive resistances. According to the signal collected by sensors, the control signal drives step motor to rotate, so that the system can follow the sun, ensuring that solar panel is always vertical to the sunlight, so it can absorb and convert solar energy to the maximum extent.
