Abstract
An automatic cleaning system for solar panels has a time controller, a detection device, a perfusion device, a driving device and a cleaning device. Based on predetermined time values, execution signals are sent to the perfusion device, the driving device and the detection device to implement prompt assessment of the need for cleaning and cleaning, if warranted. Also provided is an automatic cleaning method using the system.
Claims16
An automatic cleaning system for solar panels covered by a protection panel, comprising:
- a cleaning device, provided on the protection panel;
- and
- a driving device capable of driving the cleaning device.
- a detection device connected with the cleaning device and the driving device and capable of to determining whether the solar panel need to be cleaned.
1 more element
A method for automatically cleaning solar panels, comprising:
- providing an automatic cleaning system for a solar panel;
- 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, and acquiring the difference between the environment light intensity and the transmitted light intensity;
- comparing the acquired difference with a predetermined value, and if the acquired difference exceeds the predetermined value, the solar panel is cleaned, and if the acquired difference is less than the predetermined value, the solar panel is not cleaned;
- and
- if the solar panel is to be cleaned, transmitting execution signals to a perfusion device and a driving device, whereby the driving device drives a cleaning device to clean the solar panel.
