The present invention relates to a solar panel cleaning device, more specifically, by allowing the cleaning device to be directly supported and moved to the side of the solar panel, so that it is possible to quickly install and work without a separate rail or the like. It is possible to combine the washing part and the moving part detachably, so that regardless of the size and number of solar panels, it is possible to wash at a time through a single washing device. It relates to a sliding-type solar panel cleaning device as possible.
