Protective solar power supply system with high power generation efficiency

Abstract

The invention relates to a protective solar power supply system with a high power generation efficiency. The system includes a solar power supply device, wherein the solar power supply device comprises a photovoltaic panel and a connecting box in a cuboid shape; the photovoltaic panel is arranged in the connecting box and is parallel to the plane where the top of the connecting box is located; a sliding groove is formed in one side of the connecting box; the sliding groove is matched with the photovoltaic panel; the photovoltaic panel is inserted into the sliding groove; a moving mechanism isarranged in the connecting box; a cleaning mechanism is arranged on the side, provided with the sliding groove, of the connecting box. According to the protective solar power supply system, the function of removing dust on the photovoltaic panel is realized through the cleaning mechanism, dust is prevented from influencing light absorption of the photovoltaic panel, and the power generation efficiency is improved; and the function of driving the photovoltaic panel to move is achieved through the moving mechanism, so that the photovoltaic panel can be moved into the connecting box in hail weather, and the photovoltaic panel is protected from being damaged by hail impact.

Description

technical field [0001] The invention relates to the field of new energy batteries, in particular to a protective solar power supply system with high power generation efficiency. Background technique [0002] A solar cell is a type of new energy cell. A solar cell is a photoelectric semiconductor sheet that uses sunlight to generate electricity directly. As long as it is illuminated by light that meets certain illumination conditions, it can output voltage instantly and generate current when there is a circuit. In physics, it is called solar photovoltaic, or photovoltaic for short. A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. The implementation of solar cells by thin-film batteries is still in its infancy. [0003] After the existing solar cells are used for a long time, there will be more dust on the surface, and the dust will affect the absorption of light by the solar cells, t...

Problems solved by technology

[0003] After the existing solar cells are used for a long time, there will be more dust on the surface, and the dust will affect the absorption of light by the solar cells, thereby reducing the power generation efficiency. Not only that, when the hail weather occurs, the surface of the solar cells is vulnerable to hail Damaged by the impact, reducing the protective effect
