The invention discloses a solar street lamp which comprises a lamp post, a
solar cell panel supporting rod, a
solar cell panel, a street lamp supporting rod, a street lamp mounting base and a street lamp body. A
solar cell panel supporting rod and a street lamp supporting rod are arranged on the left and right sides of the upper end of the lamp post correspondingly. The outer sides of the solar
cell panel supporting rod and the street lamp supporting rod are respectively provided with a solar
cell panel and a street lamp supporting rod which are vertical to the
sunlight when the sun just rises; street lamp installation bases are fixed to the outer sides of the street lamp supporting rods. A street lamp for illumination is arranged at the bottom of the street lamp mounting base; and the solar street lamp further comprises a deflection mechanism which is used for driving the solar
cell panel to rotate along with the rising direction of the sun. According to the solar street lamp, by arranging the deflection mechanism, the solar
cell panel can be kept approximately perpendicular to
solar illumination continuously, and therefore the illumination conversion efficiency is improved; by arranging the lifting mechanism, the heights of the street lamp and the solar
cell panel can be conveniently adjusted, and therefore maintenance and cleaning are convenient.
