The traditional solar power system is installed by focus sun in fixed angle. It will not trace sun moving track. But, the output power of solar panel is affected by the angle and the strength of sun shine. And the traditional solar power system not always get the upright angle of input sun shine. So the absorbed energy is limited. To increase the power absorbed by solar panel as maximum, we need to use sun focus and tracking system to improve the power generation efficency. This paper is focusing on how to improving power generation efficiency by implementing 2-axises auto sun tracking system. The sun focus system mentioned in this paper is using image sensor device to detect the sun current location by projection method and using DSP to process the image get by image sensor and calculate the angle for motor to rotate to the right angle of X-axis and Y-axis. In this way, the solar panel will always focus the sun and thus achieve a real time sun focus system. Image sensor device is like human eyes to get the image of outside world and DSP is like the human brain to think and judge the information. So by using the DSP equipped with the Image sensor component, we can get the real time sun movement and location more precisely. And, by using projection method, we can prevent over exposure cause by sun light shining on the image sensor directly and the angle extension got is better, too. And, In this paper, by using the recycled material in our daily life. So this implementation is both good to environment protection and meet the goal of CO2 reduction and green design.
