Cleaning method of photovoltaic cleaning robot and photovoltaic cleaning system

The invention discloses a cleaning method of a photovoltaic cleaning robot and a photovoltaic cleaning system. The method comprises the following steps: collecting real-time meteorological data; obtaining a cleaning angle range according to the real-time meteorological data; whether the real-time meteorological data and the angle of the photovoltaic tracker where the current photovoltaic panel to be cleaned is located are within the cleaning angle range or not is judged, and if yes, the cleaning task is executed; and when it is judged that the cleaning task is started to be executed, the photovoltaic cleaning robot cleans the current photovoltaic panel to be cleaned, communicates with the photovoltaic trackers of the next group of photovoltaic panels to be cleaned, and rotates the photovoltaic trackers of the next group of photovoltaic panels to be cleaned to the cleaning angle. According to various real-time climates, corresponding strategies for the photovoltaic cleaning robot and the photovoltaic tracker t
