A Solar Power Storage Trolley

In order to improve the accumulating efficiency of solar energy, we designed a trolley with a 2-DOF attitude regulation structure of solar panels. hi it, a solar orientation sensor was used to detect the solar orientation and the solar light intensity. A trolley's differential wheels and a steering engine were used to keep the solar panels of the trolley vertically facing the Sun. At a certain interval, the steering engine adjusted the elevation angle of the solar panels and the trolley's differential wheels adjusted the solar panels' azimuth angle. Test experiment results show that the trolley can improve the accumulating efficiency of solar energy.
