The demand on resource is increasing when human beings have entered the 21st century, as the one-time fossil fuels get mined-out, such as coal, natural gas and petroleum the energy crisis has become a central issue. Because the solar energy density is small and the solar orientation changes over time, it’s difficult to collect, transmit and store the solar energy. Therefore, the utilization of solar energy is improved by using the technology of high-power condenser and automatic tracking, and the scope of solar energy application is also expanded. Tracking photovoltaic system be made of sun sensor, automatic tracking control system, the tracking actuator, solar panel, battery. With the guidance of the sensor, the control system can accurately track the position of the sun, so that the solar panel is always vertical to sunlight, to maximize use of eventually reaching solar efficiency. Data show that the utilization efficiency of solar energy can be improved about 10%.
