PROBLEM TO BE SOLVED: To provide a cleaning device of a solar panel which reduces a load acting on a guide motor in elevating a cleaning body, and suppresses an increase of power consumption of the guide motor.SOLUTION: A cleaning device of a solar panel includes: a cleaning body which contacts with a light receiving surface inclined to a horizontal direction of the solar panel and cleans it; a movement guide part which holds the cleaning body and reciprocates the cleaning body in a vertical direction by following an inclination of the light receiving surface; a guide motor which drives the movement guide part; and biasing means which biases the cleaning body in an upper direction which follows the inclination of the light receiving surface. The biasing means is a weight member, and biases the cleaning body in the upper direction which follows the inclination of the light receiving surface when a weight of itself acts in a lower direction which follows the inclination of the light receiving surface. |
