Description

Technical Field

[0001] The utility model relates to the technical field of solar energy, and more specifically to a flexible integrated solar cell panel. Background Art

[0002] A solar panel is a device that converts solar energy into electrical energy. Its working principle is based on the photoelectric effect. When sunlight shines on a solar panel, photons interact with semiconductor materials (such as silicon) on the surface of the solar panel to generate electric charges. These charges are collected by wires to form an electric current, thereby achieving the conversion of solar energy into electrical energy.

[0003] As the concept of energy conservation and environmental protection has become more popular and the photovoltaic field has developed rapidly, the technology of generating electricity with solar cells has continued to improve and has been applied in more fields. Conventional integrated solar panels (i.e. integrated folding bags) have a high fragmentation rate, are heavy, and have a poor outdoor experience; although conventional thin-film solar panels can effectively resist fragmentation and are light, they have low efficiency and thermal deformation after the operating temperature is too high, which are unavoidable technical defects. The thermal deformation of solar panels will not only affect their appearance and aesthetics, but more importantly, will have a negative impact on their performance and lifespan.

[0004] Therefore, there is an urgent need for an integrated flexible solar panel that can not only achieve light specifications and weight, but also ensure the impact resistance of the battery cells, and can also supplement the light intensity to increase the power generation efficiency, while taking into account the usage scenarios of different temperatures.

[0031] The utility model is implemented as follows Figure 1-Figure 5 As shown in, it relates to a flexible integrated solar panel, including a battery layer 1 and a composite material layer 3, a polymer layer 4 and a cloth layer stacked on both sides of the battery layer 1, a light enhancement layer 2 is provided on one side of the battery layer 1, and an anti-thermal distortion layer 5 is provided on the other side of the battery layer 1, and the composite material layer 3 is arranged between the light enhancement layer 2 and the anti-thermal distortion layer 5. Furthermore, the utility model is provided with a battery layer 1 that can be used to receive sunlight for power generation, the polymer layer 4 and the cloth layer are used to protect the battery layer 1 and isolate the battery layer 1 from the external environment, the light enhancement layer 2 can be used to increase the intensity of light irradiated on the battery layer 1, so as to increase the power generation efficiency of the battery layer 1, and the anti-thermal distortion layer 5 can be used to increase the stability of the solar panel structure.

[0032] See also Figure 1-Figure 3 The composite material layer 3 is made of a mixture of fibers and impregnated rubber particles, so as to improve the impact resistance of the battery layer 1 and have little effect on the weight of the lightweight solar panel module, thereby ensuring the portability of the lightweight solar panel module.

[0033] In this embodiment, the light enhancement layer 2, the anti-thermal distortion layer 5, the composite material layer 3, the polymer layer 4 and the fabric layer can all be made of transparent materials to ensure that the solar panel structure has a certain strength while not affecting the sunlight irradiating on the battery layer 1.

[0034] See also Figure 1-Figure 3 In this embodiment, the battery layer 1 includes a battery cell 101 and a film protective layer 102 arranged on both sides of the battery cell 101. The existence of the film protective layer 102 can prevent the battery cell 101 from being eroded by the external environment, such as rain, snow, sand, dust, etc., thereby improving the durability and extending the service life of the battery cell 101. The film protective layer 102 has a high light transmittance, which helps the battery cell 101 to fully absorb solar energy and improve the power generation efficiency of the photovoltaic module. The film protective layer 102 has a high water vapor barrier property and can effectively prevent water vapor from entering the battery cell 101 and affecting the normal operation of the battery circuit. At the same time, the film protective layer 102 also has a certain strength and can play a structural support role during the component installation process to ensure the safety and stability of the solar panel.

[0035] In this embodiment, at least one polymer layer 4 is provided and is disposed on a side of the light enhancement layer 2 and / or the anti-thermal distortion layer 5 away from the battery layer 1 .

[0036] See also Figure 1-Figure 3 In this embodiment, the polymer layer 4 can be made of polytetrafluoroethylene material to enhance the weather resistance of the solar panel. Under extreme weather conditions, such as high temperature and humidity, the solar panel is easily damaged. The addition of fluoride can greatly improve the solar panel's resistance to high temperature, cold, humidity and ultraviolet rays, thereby ensuring that the solar panel can work stably in various environments.

[0037] In this embodiment, the composite material layer 3 includes a substrate body 301, and the substrate body 301 includes one or more layers of glass fiber and / or carbon fiber material. Granular or molten thermoplastic resin 302 is arranged on both sides of the substrate body 301. Furthermore, the thermoplastic resin 302 has good waterproof and moisture-proof properties, which can prevent moisture from invading the interior of the solar panel, thereby protecting the internal electronic components and circuits. The thermoplastic resin 302 can ensure that sunlight is fully irradiated on the battery cell 101, thereby increasing the power generation capacity of the battery cell 101. Optionally, the thermoplastic resin 302 can be at least one of EVA plastic, POE plastic, polyester resin, acrylic resin, and epoxy resin.

[0039] In this embodiment, the anti-thermal distortion layer 5 includes one or more layers of transparent PC film and / or one or more layers of transparent PCB. The anti-thermal distortion layer 5 is arranged on the backlight side of the battery layer 1, and plays a supporting and reinforcing role when the ambient temperature changes. Due to the continuous effect of solar radiation, the internal temperature of the solar panel will rise, thereby generating thermal stress. This thermal stress may cause the solar panel to deform, affecting its performance and life. The anti-thermal distortion layer 5 can effectively reduce this thermal stress, thereby reducing the risk of distortion.

[0040] In this embodiment, the battery layer 1 , the light enhancement layer 2 , the composite material layer 3 , the polymer layer 4 , the anti-thermal distortion layer 5 and the fabric layer are all bonded and packaged with a packaging film 7 .

A limiting protrusion 809 is provided at one end of the limiting plate 808 away from the sliding groove. The limiting plate 808 can slide out of the sliding groove so that when the solar panel is placed on the anti-slip bearing plate 801, the limiting protrusion 809 acts on both ends of the solar panel to prevent the solar panel from falling.
