Description

Technical Field

[0002] Solar photovoltaic (PV) panels, also known as solar cells, are semiconductor optoelectronic devices that utilize the photovoltaic effect of sunlight to directly convert solar radiation energy into electrical energy. They are typically assembled from multiple solar cells connected in series and parallel, encapsulated within glass, a backsheet, and a protective frame. These cells usually use semiconductor materials such as silicon. When sunlight shines on the cells, it excites electron-hole pairs. Under the influence of the electric field inside the cell, the electrons and holes separate and move in different directions, thus forming an electric current and converting solar energy into electrical energy. PV panels are the core component of a solar photovoltaic power generation system, and their performance and quality directly affect the power generation efficiency and stability of the system.

[0003] A solar photovoltaic (PV) panel cleaning device is a piece of equipment used to clean specific objects. It uses various technical means and mechanical structures to remove dust, dirt, leaves, and bird droppings adhering to the surface of the solar PV panel, maintaining its cleanliness. The cleaning device can achieve its cleaning function in multiple ways, using brushes and scrapers for physical contact. The aim is to ensure that the solar PV panel can receive sunlight to the maximum extent, reducing light reflection and shading caused by surface contaminants, thereby improving the power generation efficiency of the PV panel, extending its service life, and ensuring the stable operation of the solar PV power generation system. However, existing solar PV panel cleaning devices cannot adapt to various heights, resulting in a small cleaning area and low efficiency.
