Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panels, and in particular to a solar photovoltaic panel with an anti-shading structure. Background Art

[0002] A solar photovoltaic panel is a device that uses the photovoltaic effect to convert solar energy into electrical energy. It is mainly made of semiconductor materials such as silicon, and it absorbs photons in sunlight to stimulate electrons to generate current. Solar photovoltaic panels are clean, renewable, and flexible to install. They are widely used in homes, businesses, and industries to provide people with green energy. Their performance depends on factors such as material quality, manufacturing process, and lighting conditions. With the continuous advancement of technology, the efficiency and reliability of solar photovoltaic panels are gradually improving, and their costs are gradually decreasing, playing an important role in promoting global energy transformation.

[0003] When in use, photovoltaic panels are usually placed outdoors. There are a lot of dust and other impurities in the outdoor environment, which can easily cover the photovoltaic panels and cause uneven lighting. Uneven lighting will cause different areas of the solar panel to receive different intensities of sunlight, resulting in inconsistent electrical energy generated in each area. This will make the output power of the entire solar panel unstable and difficult to achieve the designed optimal output power. Areas with strong light will generate more current, while areas with weak light will have less current. If this difference is large, local hot spots may form inside the solar panel. The temperature in the hot spot area will increase, which will not only reduce the power generation efficiency of the area, but may also damage the solar cells and shorten the service life of the solar panel. Therefore, we propose a solar photovoltaic panel with an anti-covering structure. Summary of the invention

[0007] Wherein, the protection mechanism comprises:

[0008] A protective plate, which is made of ETFE plastic and is used to cover the top of the photovoltaic array. A rotating frame is symmetrically arranged on one side of the protective plate close to the bottom plate, and a side of the rotating frame away from the bottom plate is fixedly connected to the inner side of the protective plate;

[0009] A spring plate, which is arranged in a V-shape and is used to support two rotating frames, the two sides of the spring plate are respectively fixedly connected to the two rotating frames on one side away from the protective plate, a fixing seat is arranged at the interval between the two rotating frames, and the two fixing seats on the sides close to each other are fixedly connected to the surface of the spring plate;

[0012] The light shines on the protective plate, and then passes through the protective plate and shines on the photovoltaic panels on the photovoltaic array. The photovoltaic panels convert solar energy into electrical energy, and finally transmit the electrical energy to the energy storage device. The protective plate covers the photovoltaic array, which can prevent dust, rain and other impurities from directly contacting the photovoltaic array, and can play a good protective effect. When cleaning impurities, it can prevent tools from directly contacting the photovoltaic panels, and can prevent the photovoltaic panels from being scratched, and the power generation efficiency from being affected. ETFE plastic material has good elasticity and light transmittance, can withstand light for a long time, is not easily corroded, and can protect the photovoltaic array for a long time. When there is wind, the disturbance component will shake under the drive of the wind, and the shaking will be transmitted to the rotating frame, which can drive the protective plate to shake and deform when there is wind, which will have an adverse effect on the adhesion Impurities such as fallen leaves on its surface are peeled off and shaken off, and when there is wind, the natural wind can further completely peel off the initially peeled impurities and blow the impurities away, which can effectively prevent the protective plate from being covered for a long time. The elastic structure of the strengthened component can limit the elasticity of the protective plate within an appropriate range to prevent the protective plate from frequent deformation and fatigue. When the protective plate is hit, the protective plate moves, driving the rotating frame to move, and the spring plate is deformed, thereby acting as a buffer to prevent damage to the protective plate. At the same time, the protective plate deforms and vibrates after the deformation is restored, which can further peel off impurities such as dust and fallen leaves.

When there is no wind and impact for a long time, impurities will gather in the depressions, and other parts will still have good light transmission effects. The photovoltaic array can still maintain a good working effect. At the same time, the curved surface of the protective plate can refract light. When the photovoltaic array is covered, it can ensure that the entire photovoltaic array can be illuminated more evenly, avoiding uneven illumination, avoiding uneven current and voltage distribution inside the photovoltaic array causing accelerated aging, and avoiding uneven illumination causing repeated thermal expansion and contraction and stress changes of solar cell materials.

The movement of the column drives the limiting plate to deform, and under the elastic force of the limiting plate to restore the deformation, the column completes the reset, thereby maintaining the waveform distribution of the column, ensuring the diversion effect of rainwater and impurities.
