The invention relates to a solar street light, which comprises a lamp post, a solar panel, a battery, a control module, a base, a lamp tube and a lamp tube controller. The input end of the battery control module is connected with the solar panel, the output end of the battery control module is connected with the battery; the battery is connected with the lamp tube controller, the lamp tube controller is connected with the lamp tube, the periphery of the lamp post is provided with a transparent cover, and the lamp tube is arranged in the lamp post. The solar street light is characterized in that the solar panel is a mono-crystal line silicon solar cell. The invention has the advantages that: the bulb of the traditional street light is not used as the light source, the lamp post is made of transparent material, and the lamp tube is arranged in the lamp post. Since the lamp post can directly emit light, the invention reduces the height of the light source and the loss of the surrounding illumination, thereby achieving the effect of reducing the energy consumption and facilitating the continuous power supply of the solar cell.
