The utility model discloses a solar street lamp relates to the technical field of lamps and lanterns, including the lamp pole and a plurality of
solar energy institutions, the lamp pole is parallel to the up and down direction, a plurality of
solar energy institutions are arranged on the lamp pole along the up and down direction, and the light receiving surface of a plurality of
solar energy institutions is perpendicular to the horizontal direction. In the
morning,
evening etc. When the solar
elevation angle is small, the light of low angle
oblique incidence and the incident angle of the light receiving surface of the vertical setting of solar energy institution significantly reduce, make the light more close to the front illumination state, the
energy loss of traditional horizontal light receiving surface because of the large angle reflection is reduced greatly, effectively improve the
photoelectric conversion efficiency of solar energy institution in the
morning and
evening period, and then be favorable to guarantee the illumination effect of solar street lamp in the
morning and
evening period.
