The core of the solar street lamp is the solar panel which can convert solar energy into electric energy, but the utilization rate of the solar energy is low due to the fact that the conversion efficiency of the solar panel is about 25%, and therefore the solar street lamp has great significance on how to improve the utilization rate of the solar energy. At present, most of solar panels in street lamp systems are fixedly installed, and the solar panels are not complete enough in light collection, so that the utilization rate of solar energy is low. For example, in our country, for a fixedly installed solar cell panel, the inclination angle relative to the horizontal plane is preferably 30-40 degrees, the direction is the best in the south, and the ideal inclination angle is the inclination angle which enables the annual power generation amount of the solar cell to be as large as possible, and the difference between the power generation amounts in winter and summer is as small as possible, and the local latitude or the local latitude plus several degrees is generally taken as the inclination angle for installing the local solar cell module.
