Monitoring operation and maintenance method, system and device for photovoltaic power station, and storage medium

The invention relates to a monitoring operation and maintenance method, system and device for a photovoltaic power station, and a storage medium. According to the technical scheme, the method comprises the following steps: obtaining dust images on all photovoltaic panels; calculating the amount of dust on each photovoltaic panel according to the dust image; the dust quantity on each photovoltaic panel is compared with a preset dust threshold value, and the dust rating of each photovoltaic panel is obtained; according to the dust rating of each photovoltaic panel, a corresponding preset cleaning mode is selected to correspondingly clean each photovoltaic panel, and the cleaning state of each photovoltaic panel is monitored in real time; according to the cleaning state of each photovoltaic panel, the cleaning effect of each photovoltaic panel is recognized, and if the recognition result is that the photovoltaic panel is cleaned thoroughly, cleaning is stopped; if the recognition result is that cleaning is abnor
