Abstract
    Solar energy as a new energy, which it compared with the conventional and conventional energy has three advantages: first, it is human can be utilized most abundant energy; second, on Earth, wherever there are solar energy, local development and use, there is no transport problems, especially in rural areas with poor communications, islands and remote areas more valuable use; and thirdly, solar energy is a clean source of energy. Therefore, use of solar energy has been a top priority. Solar panel orientation tracking control system allows the utilization of solar energy greatly increased so the solar panel orientation tracking studies are necessary.
    In the study of this design it is to improve the utilization of solar energy, a new single-chip based on fixed tracks roughly tracking and photoelectric sensors to accurately track the dual-mode solar tracking controller. Among them, the fixed trajectory tracking mode is for the controller to track the sun during the day computing device in accordance with the relevant formulas and parameters of position (depending on date of exercise), then converted to the corresponding pulse is sent to the drive, the drive motor in real time to track the sun. Photoelectric sensors accurately tracking control is performed by five ordinary photodiode to achieve precisely track the sun signal strongest point, so sunlight illuminated vertical panels, improve the utilization of solar energy.
