[0054] Step 1: Calculate the pressure F generated by air flow on the photovoltaic panel 3 according to formula (1), the wind speed sensor and the angle sensor detection values. g :

[0055]

[0056] Wherein δ is the wind coefficient (wind coefficient refers to the coefficient of wind acting on the structure related to the structure size, with a value range of 0.68-0.79), ρ is the air density, θ is the angle sensor detection value, sin is sine, V is the wind speed sensor detection value, A is the wind-exposed area of ​​the photovoltaic panel 3, λ is the environmental impact coefficient (a parameter used to measure the degree of environmental impact of a specific activity or project, with a value range of 0.70-1.15), μ is the terrain characteristic coefficient (used to describe and quantify the impact of terrain on a specific phenomenon or process (such as water flow, climate, land use, etc.), with a value range of 0.15-0.37), is the wind direction influence coefficient (used to measure the influence of wind direction on a specific phenomenon or process, with a value range of 0.23-0.59);

[0065] The controller compares the actual total pressure of the air flow on the photovoltaic panel 3 and the angle adjustment mechanism with the preset total pressure range. When the actual total pressure is higher than the preset total pressure range, the controller controls the alarm to sound an alarm, thereby reminding the staff to effectively reinforce the photovoltaic panel 3 support mechanism in time so that it can operate normally, thereby meeting the user's needs for this type of solar photovoltaic panel cleaning device.
