Thermal power plants in Taiwan dominate electric power generation, and it has been reported that are the major contributor of CO2 emission. To prevent the effects related to global warming caused by GHG emission, the renewable energy has been the best substitution strategy. 40 minutes of total solar radiation on earth could provide enough power to meet the energy needs of all human beings for approximately one year therefore, the potential of solar energy is virtually limitless. Moreover, by means of solar powered batteries, solar energy can be directly converted to electrical power. Since it neither pollutes the environment or ecology, solar is an extremely clean source of energy. The life-span of solar cell is very long, possibly 20 years or more. The capability of solar panel to provide energy approximately follows the intensity of the sunlight. This project propose a dual-axis solar tracking system with a new designed sun-position tracker and ZigBee based monitoring/control system. This dual-axis solar tracking system controls elevation and orientation angles of solar panels such that the panels always maintain perpendicular to the sunlight. About tracking the angle of the sun, and further controlling the motor to adjust the tracking angle to follow the sun so that the direct sunlight could be acquired on the motor to increase its power.
