A solar power generation system according to claim 8, characterized in that: The controller controls the alarm to work based on the solar radiation meter and the temperature sensor, including the following steps: Step 1: According to formula (1) and the detection values ​​of the solar radiation meter and the temperature sensor, calculate the actual working temperature T of the photovoltaic panel when dust adheres to the surface of the photovoltaic panel during the power generation process of the environmentally friendly solar module c : Among them, T c is the actual working temperature of the photovoltaic panel after dust adheres to the surface of the photovoltaic panel, τ is the transmittance of the photovoltaic panel, I is the detection value of the irradiance intensity on the surface of the environmentally friendly solar panel when it is generating electricity by the solar radiometer, S is the effective area of ​​the photovoltaic panel, η0 is the power generation efficiency of the photovoltaic panel under theoretical conditions, λ is the battery temperature coefficient under theoretical conditions of the photovoltaic panel, T is the detection value of the ambient temperature of the environmentally friendly solar panel when generating electricity by the temperature sensor, k is the absorption rate of the photovoltaic panel, T0 is the working temperature of the photovoltaic panel under theoretical conditions, U a , U b is the heat loss coefficient of the front plate (4) and the rear plate (5) in the environmentally friendly solar panel; Step 2: According to the following formula (2), the actual output power W of the current environmentally friendly solar panel power generation process is calculated. The controller compares the actual output power W of the current environmentally friendly solar panel power generation process with the preset output power range. When the actual output power is lower than the preset output power range, the controller controls the alarm to sound an alarm: W=I×τ1×η0×S×[1-λ×(T0-T| c )] (2); Among them, W is the actual output power of the current environmentally friendly solar panel power generation process, and τ1 is the transmittance of the outer layer of the photovoltaic panel.
