Photovoltaic panel self-checking and self-cleaning device and use method

The invention relates to the technical field of photovoltaic panel maintenance, and discloses a photovoltaic panel self-checking and self-cleaning device and a use method.The photovoltaic panel self-checking and self-cleaning device comprises a dust self-checking data processing end used for dust self-checking and a sweeping processing end used for cleaning a photovoltaic panel; the target distance between the cavitation nozzle and the photovoltaic panel is 30 mm, the divergence angle of the cavitation nozzle is 30 degrees, the convergence angle of the cavitation nozzle is 13.5 degrees, and the diameter of the cavitation nozzle is 1.3 mm; power change is used as a dirt judgment basis of the photovoltaic panel, a dust removal mode based on self-detection and cavitation jet flow is adopted, when the dirt accumulation amount reaches a certain threshold value, the cavitation jet flow spray head is automatically controlled to work, and the cavitation spray head is arranged based on the cavitation jet flow principl
