[0002] The global demand for new energy is growing, especially the new energy industry represented by photovoltaics is gradually growing, and the construction of photovoltaic power stations is accelerating. Due to the demand for light and land, photovoltaic power stations are mostly built in deserts or marine beaches far away from cities. Attachments such as wind, sand, sea salt, and bird droppings have a serious impact on the efficiency of photovoltaic power generation, and remote areas rely on daily manual operation and maintenance, which creates unfavorable factors.
