Driven by my country's strong photovoltaic industry, photovoltaic power generation has been widely used around the world.

A layer of transparent electrode (lower electrode) is covered on the solar panel, such as aluminum-doped zinc oxide (AZO) or indium tin oxide (ITO) electrode, and an electrode plate (upper electrode) is placed at a certain distance on top and bottom. A DC high voltage is applied between the electrodes, and the high voltage electric field charges the dust on the lower electrode and removes it from the surface of the lower electrode under the action of electrostatic force. The movement of the upper electrode plate controlled by the motor traverses the entire solar panel covered with transparent electrodes to complete dust removal. This solution requires adding transparent electrodes on the solar panel, which increases the cost of the solar panel; the moving device of the upper electrode plate increases the complexity and energy consumption of the dust removal device, making the cost higher; this solution is suitable for environments with relative humidity greater than 30%.

The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, but should not be construed as limiting the present application.
具体而言，图1为根据本申请实施例提供的一种自供能太阳能板静电除尘装置结构示意图。Specifically, FIG. 1 is a schematic structural diagram of a self-powered solar panel electrostatic precipitator provided according to an embodiment of the present application.
如图1所示，该自供能太阳能板静电除尘装置10包括：电源模块100、作为下电极的
太阳能板200和上电极300。As shown in FIG1 , the self-powered solar panel electrostatic precipitator 10 comprises: a power module 100, a Solar panel 200 and upper electrode 300 .
其中，电源模块100用于提供直流高电压。太阳能板200内部的电极与电源模块100的一端相连。上电极300以预设间距设置于太阳能板200上方，并与电源模块100的另一端相连，以与太阳能板200构成电容，利用电容与太阳能板200之间产生的非均匀电场使得太阳能板200上的灰尘极化，并在非均匀电场作用下受介电电泳力，使得极化后的灰尘脱离太阳能板200的表面，完成太阳能板200的静电除尘任务。Among them, the power module 100 is used to provide DC high voltage. The electrodes inside the solar panel 200 are connected to one end of the power module 100 . The upper electrode 300 is disposed above the solar panel 200 at a preset distance and is connected to the other end of the power module 100 to form a capacitor with the solar panel 200. The non-uniform electric field generated between the capacitor and the solar panel 200 is used to cause the upper electrode 300 to The dust is polarized, and is subject to dielectrophoretic force under the action of the non-uniform electric field, causing the polarized dust to break away from the surface of the solar panel 200, completing the electrostatic dust removal task of the solar panel 200.
