Title:
ELECTROSTATIC DUST REMOVAL APPARATUS AND METHOD FOR SELF-POWERED SOLAR PANEL
Document Type and Number:
WIPO Patent Application WO/2024/060980
Kind Code:
A1
Abstract:
An electrostatic dust removal apparatus and method for a self-powered solar panel. The apparatus comprises: a power supply module (100), which is used for providing a direct-current high voltage; a solar panel (200), which is used as a lower electrode, wherein an electrode inside the solar panel (200) is connected to one end of the power supply module (100); and an upper electrode (300), which is arranged above the solar panel (200) at a preset distance and is connected to the other end of the power supply module (100), so as to form a capacitor with the solar panel (200), wherein dust on the solar panel (200) is polarized by using a non-uniform electric field between the capacitor and the solar panel (200), and the dust is subjected to a dielectrophoresis force under the action of the non-uniform electric field, such that the polarized dust is separated from the surface of the solar panel (200), and an electrostatic dust removal task of the solar panel (200) is completed in combination with the action of gravity. Accordingly, dust removal of a solar panel can be achieved without consuming water, without depending on manpower, without requiring additional moving apparatuses, and without adding anything on the solar panel (200), and there is no requirement for humidity, such that an application environment is wide, a power supply circuit is simple, the power consumption is low, and the cost is low.
