The invention discloses a solar streetlamp. The solar streetlamp comprises a solar battery panel (1), an illumination lamp (2), a lamp post (3), a rotary head (5) and a storage battery (6), wherein the solar battery panel (1) is mounted at the top of the lamp post (3) through the rotary head (5); the solar streetlamp further comprises a control circuit and a light induction sheet (11); the light induction sheet (11) is used for determining an inclined angle between the solar battery panel (1) and the sun and pushing the inclined angle to the control circuit; the control circuit is used for controlling the rotary head (5) to rotate according to the inclined angle between the solar battery panel (1) and the sun, so that the angle between the solar battery panel (1) and the sun is adjusted. With the adoption of the solar streetlamp, the angle between the solar battery panel (1) and the sun can be adjusted in real time so that the power generation amount of the solar battery panel (1) is the largest.
