(1) The cleaning time is best to choose in the early morning, evening or night, avoid cleaning at high temperature periods such as noon, so as to avoid damage to the solar panels.
(2) When cleaning, avoid using hard and sharp objects to directly touch the solar panel.
(3) Solar panels, brackets and other parts cannot be stepped on, which may damage the power station and affect its service life.
According to the current industry operation and maintenance experience, in winter and other rainy and snowy seasons, it is generally sufficient to clean it once a month (if there is snow accumulation, it should be cleaned in time), and it can be cleaned twice a month in the rest of the month. The windy and dusty areas such as the northwest need to be determined according to the specific conditions.
It should be noted that: try not to use soapy water when cleaning the module. Usually when we wash our hands with soap, a thin film will be left on the hands. The same reason, after washing the module with soap, it will also leave on the surface of the photovoltaic module. A layer of film or residues will encourage dust to adhere and accumulate more quickly, affecting the power generation capacity of the power station. In addition, other corrosive cleaning agents should not be used.
