1. A solar panel cleaning system comprising:
a detection traveling vehicle configured to travel on a solar panel and including one or more sensors configured to detect dirt on the solar panel;
at least one processor configured to:
generate a dirt map including dirt positions of detected dirt on the solar panel on the basis of detection results sensed by the one or more sensors of the detection traveling vehicle; and
generate a cleaning path for performing cleaning of the solar panel on the basis of the generated dirt map; and
a cleaning traveling vehicle configured to travel on the solar panel on the basis of the generated cleaning path and perform cleaning of the solar panel;
wherein the one or more sensors are configured sense a respective dirt degree of detected dirt on the solar panel for each position of detected dirt and the processor is configured to generate the dirt map such that it includes dirt positions and respective dirt degrees for detected dirt on the solar panel, and
wherein the processor is configured to generate the cleaning path such that the cleaning traveling vehicle passes through dirt positions of detected dirt a plurality of times when the respective dirt degree is higher than a predetermined reference dirt degree.
