Automatic cleaning method for solar panel

Abstract

A method for automatically cleaning a solar panel, includes: obtaining an environmental intensity of sunlight in the outside environment with an environmental light sensor; obtaining a transmitted intensity of incident sunlight throughout the protection panel with a transmission light sensor; deriving a detection difference value between the environmental intensity and the transmitted intensity; comparing the detection difference value with a predetermined value. Wherein if the detection difference value is larger than the predetermined value, the solar panel will be cleaned; if the detection difference value is smaller than the predetermined value, the solar panel will not be cleaned; the driving device sends execution signals to a perfusion device and a driving device so as to the driving device drives a cleaning device to clean the solar panel when the solar panel needs to be cleaned.

1 . A method for automatically cleaning a solar panel, comprising:
 measuring an environmental light intensity via an environmental light sensor;   measuring a transmitted light intensity through a protection panel covering the solar panel via a received light sensor;   acquiring the difference between the environment light intensity and the transmitted light intensity;   comparing the acquired difference with a predetermined value;   transmitting execution signals to a perfusion device and a driving device upon a condition that the acquired difference exceeds the predetermined value; and   driving a cleaning device to clean the solar panel by using the driving device.   
     
     
         2 . The method as claimed in  claim 1 , wherein the method further comprises:
 providing a time controller;   setting an initial time, a regular detection time point, a cleaning time point and a cleaning duration for each cleaning time;   determining if a current time conforms to the cleaning time point or the detection time point, and if the current time conforms to the cleaning time point, sending an execution signal to the perfusion device and the driving device to clean the solar panel, and if the current time conforms to the regular detection time point, sending an execution signal to re-implement measurement of the environmental and transmitted light intensities.   
     
     
         3 . The method as claimed in  claim 2 , further comprising sending a timer signal to the time controller when the driving device and the perfusion device begin to clean, and after the cleaning duration passes, sending a stop signal via the time controller to the driving device and the perfusion device to stop cleaning
