However, a harsh truth before the people , energy , etc. are now using either coal, oil or natural gas are finite non-renewable energy sources, such as if one day these energy depletion how to do ? In order to present the need for sustainable development , wind, hydro and solar and other renewable energy by the people higher priority . With the development of semiconductor technology photovoltaic technology is more mature , and his development is also growing. This paper discusses the methods and principles of the suns rays to track , data acquisition equipment to receive and drive control hardware and software design . This design is a real-time dual-axis solar tracking system is the core of the light detector , microcontroller and motor drive circuits. Light is detected by detecting the intensity of light sensitive resistor suns rays , and the results transmitted to the microcontroller ; each point MCU function is to receive the returned light detector to determine the direction of the light intensity and control of motor rotation ; motor drive is receiving microcontroller instruction came under the instruction rotational motor. After a series of actions can make solar panels and
