onversion efficiency. The system is based on singlechip, orbit the sun elevation angle formula using the sun and calculating azimuth and take the time chip advantage of dualaxis stepper motor driven tracking system, make the solar panels perpendicular to the solar incidence line, to improve the absorption efficiency of solar energy. At present, the design of a simple formula was only for calculating the data, the eastwest to the point of view will be changed once an hour, the northouth perspective will be changed once a day, and then the MCU to return to control things through the night to determine, as well as every haif a year to track the direction of the northsouth change in control. Because of the time and the current limitations of the knowledge of the author’s , the tracking system to track the point of view is rough , there are many errors , if the opportunity arised the design will be iomproved in the future.
