A street lamp is provided to improve generation efficiency using solar light by increasing irradiation rate of the solar light to a solar cell by cleansing a surface of a solar cell panel with a solar cell panel surface cleaning unit and moving the solar cell panel by tracking the moving sun. A street lamp includes a pole(10), a solar cell panel(20), a wind power generating unit(30), a battery, a lamp, and a solar cell panel surface cleansing unit. The pole is supported on a ground surface. The solar cell panel is rotatably installed on a top end of the pole. The wind power generator is installed by a supporting bar(31) extending from a side surface of the pole and generates power by wind power. The battery is installed in the pole, and stores electric energy generated by the solar cell panel and the wind power generating unit. The lamp emits light by receiving the electric energy of the battery. The solar cell panel surface cleansing unit cleanses a surface of the solar cell panel. |
