Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a photovoltaic panel which can generate electricity using solar energy and can be automatically cleaned. Background Art

[0002] Photovoltaic panels, also known as solar panels or photocell panels, are devices that convert solar energy into electrical energy. They consist of multiple solar cells that generate current through light, thereby achieving the conversion and storage of electrical energy. Photovoltaic panels are usually made of silicon materials, the most common of which are monocrystalline silicon, polycrystalline silicon and amorphous silicon. These materials have semiconductor properties. When sunlight shines on photovoltaic panels, photons excite electrons in the material to form an electric current. This process is called the photoelectric effect. Photovoltaic panels are widely used in solar power generation systems. They can be installed on roofs, ground or other suitable locations to capture solar energy and convert it into usable electrical energy; photovoltaic panels can also be used in combination with batteries to continue to provide power at night or on cloudy days. The advantages of photovoltaic panels include renewable, environmentally friendly, long life, low maintenance costs, etc. With the advancement of technology With continuous progress, the efficiency of photovoltaic panels is also improving, but the current photovoltaic panels do not have an automatic cleaning structure. After long-term use, dust, leaves, bird droppings and other dirt will accumulate on the surface of the photovoltaic panels. These substances will hinder the incidence of sunlight and affect the power generation efficiency of the photovoltaic panels. In sandstorm weather, a large amount of sand and dust will cover the surface of the photovoltaic panels, resulting in reduced power generation efficiency. At the same time, after rainfall, water droplets remaining on the photovoltaic panels will also form water marks, affecting the transmittance of light, and insects will also enter the gaps between the photovoltaic panels, affecting the normal operation of the photovoltaic system; therefore, regular cleaning of photovoltaic panels is an important measure to maintain their efficient power generation. For this reason, we propose a solar power generation photovoltaic panel that can be automatically cleaned to solve the above-mentioned problems. Utility Model Content
