Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation equipment, and more specifically to a photovoltaic component for increasing sunlight irradiation efficiency. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] An existing patent for a photovoltaic panel, patent authorization number CN220874479U, has a guide plate that can discharge rainwater on the photovoltaic panel assembly and the frame in time through an inverted "V"-shaped structure in heavy rain weather, which can reduce rainwater residue and penetration, and prevent it from entering the interior of the photovoltaic panel and causing damage to the photovoltaic panel. At the same time, this type of photovoltaic panel is not restricted by direction and angle when placed, and the inverted "V"-shaped guide plates arranged on the board surface of the upper frame, lower frame, left frame and right frame can all drain rainwater.

[0004] However, the photovoltaic panel in patent authorization number CN220874479U does not have the function of refracting light. It is affected by light intensity and incident angle. Light intensity refers to the light energy flow density per unit area, usually expressed in watts per square meter (W / m2). When sunlight is irradiated at an angle perpendicular to the horizontal plane, the light intensity is the maximum; when sunlight is irradiated at an oblique angle, the light intensity will weaken. The incident angle is the angle between the sunlight and the normal direction. The smaller the incident angle, the greater the light intensity. Since the incident angles of sunlight on the light-receiving surface of the photovoltaic panel are different in the morning, noon and afternoon, the power generation rate of the photovoltaic panel in the morning and afternoon is not as good as that at noon. In order to improve the irradiation efficiency of the photovoltaic panel, we have proposed a photovoltaic component that increases the efficiency of sunlight irradiation to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a photovoltaic module that increases the efficiency of sunlight exposure. It can refract incident light in the morning and afternoon through the refractive protrusions on the microstructured refractive glass, so that the angle between the incident angle and the normal direction of the light-receiving surface of the photovoltaic panel body is reduced. When the incident angle is smaller, the light intensity is greater, thereby improving the lighting efficiency of the photovoltaic panel body, and reducing the reflection of light through the anti-reflection film, the light exposure efficiency of the photovoltaic panel body can be further improved.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A photovoltaic assembly for increasing sunlight irradiation efficiency, comprising a photovoltaic panel body, a light-receiving surface of the photovoltaic panel body being provided with a microstructured refractive glass, a surface of the microstructured refractive glass away from the photovoltaic panel body being integrally formed with a refractive protrusion, and a plurality of the refractive protrusions being arranged in an array structure;

[0010] The surface of the microstructure refractive glass provided with refractive protrusions is connected to a tempered glass cover;

[0011] The inner facade of the tempered glass cover is compositely bonded with an anti-reflection film;

[0012] The outer facade of the tempered glass cover is compositely bonded with a tempered film.

[0013] Furthermore, a heating wire is embedded inside the tempered glass cover, and the heating wire is arranged in a continuous S-shaped structure.

[0014] Furthermore, a positive terminal and a negative terminal are respectively installed at the ends of the tempered glass cover, and the positive terminal and the negative terminal are respectively electrically connected to the two ends of the heating wire.

[0015] Furthermore, the positive terminal and the negative terminal are both copper sheets.

[0016] Furthermore, a boss is integrally formed at the edge of the surface of the tempered glass cover close to the microstructure refractive glass, and the boss surrounds the edge of the tempered glass cover.

[0017] Furthermore, the boss arranged at the edge of the tempered glass cover is connected to the microstructure refractive glass by bonding with EVA glue.

[0018] Furthermore, the microstructure refractive glass, the tempered glass cover and the tempered film are all ultra-white high-transmittance glass.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) In this scheme, when sunlight shines at an oblique angle, the light intensity will be weakened (such as incident light in the morning and afternoon). The incident light in the morning and afternoon is refracted by the refractive protrusions on the microstructured refractive glass, so that the angle between the incident angle and the normal direction of the light-receiving surface of the photovoltaic panel body is reduced. When the incident angle is smaller, the light intensity is greater, thereby improving the lighting efficiency of the photovoltaic panel body. By reducing the reflection of light through the anti-reflection film, the light irradiation efficiency of the photovoltaic panel body can be further improved.

[0022] (2) In this solution, the positive terminal and the negative terminal are connected to an external power source. When snow accumulates on the surface of the tempered glass cover, the heating wire is energized to melt the snow covering the surface of the tempered glass cover, thereby enabling the photovoltaic panel to receive light and generate electricity.

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0032] Example:

[0033] See also Figure 1-6 A photovoltaic module for increasing sunlight irradiation efficiency comprises a photovoltaic panel body 1, a light-receiving surface of the photovoltaic panel body 1 is provided with a microstructured refractive glass 2, a surface of the microstructured refractive glass 2 away from the photovoltaic panel body 1 is integrally formed with a refractive protrusion 3, and a plurality of the refractive protrusions 3 are arranged in an array structure;

[0034] The surface of the microstructure refractive glass 2 provided with the refractive protrusions 3 is connected to a tempered glass cover 4;

[0035] The inner surface of the tempered glass cover 4 is compositely bonded with an anti-reflection film 5;

[0036] The outer surface of the tempered glass cover 4 is compositely bonded with a tempered film 9;

[0037] It should be noted that when the photovoltaic assembly for increasing sunlight irradiation efficiency is used, the photovoltaic panel body 1 is first installed in a designated installation area using a photovoltaic frame, and the tempered glass cover 4 is protected by a tempered film 9. Figure 2 As shown, the three incident light rays are respectively incident light rays in the morning, midday and afternoon. When the sunlight irradiates at an angle perpendicular to the horizontal plane, the light intensity is the largest (such as the incident light at noon); and when the sunlight irradiates at an oblique angle, the light intensity will be weakened (such as the incident light in the morning and afternoon). The incident light rays in the morning and afternoon are refracted by the refractive protrusions 3 on the microstructured refractive glass 2, so that the angle between the incident angle and the normal direction of the illuminated surface of the photovoltaic panel body 1 is reduced. When the incident angle is smaller, the light intensity is greater, thereby improving the lighting efficiency of the photovoltaic panel body 1, and reducing the reflection of light by the anti-reflection film 5, the light irradiation efficiency of the photovoltaic panel body 1 can be further improved.

[0038] like Figure 4 , Figure 5 , Figure 6 As shown, a heating wire 8 is embedded inside the tempered glass cover 4, and the heating wire 8 is arranged in a continuous S-shaped structure. A positive terminal 6 and a negative terminal 7 are respectively installed at the ends of the tempered glass cover 4, and the positive terminal 6 and the negative terminal 7 are respectively electrically connected to the two ends of the heating wire 8, and the positive terminal 6 and the negative terminal 7 are both copper sheets;

[0039] It should be noted that, by connecting the positive terminal 6 and the negative terminal 7 to an external power source, when snow accumulates on the surface of the tempered glass cover 4, the heating wire 8 is energized to melt the snow covering the surface of the tempered glass cover 4, thereby enabling the photovoltaic panel body 1 to generate electricity by receiving light.

[0040] like Figure 1 , Figure 2 , Figure 4 As shown, a boss is integrally formed at the edge of the tempered glass cover 4 near the surface of the microstructure refractive glass 2, and the boss surrounds the edge of the tempered glass cover 4. The boss arranged at the edge of the tempered glass cover 4 is bonded to the microstructure refractive glass 2 by EVA glue.

[0041] It should be noted that it is ensured that the tempered glass cover 4 and the microstructure refractive glass 2 can be stably connected together.

[0042] like Figure 2 As shown, the microstructure refractive glass 2, the tempered glass cover 4 and the tempered film 9 are all ultra-white high light-transmittance glass;

[0043] It should be noted that the light transmittance during illumination can be improved, thereby improving the power generation efficiency of the photovoltaic panel body 1.

[0044] When in use: first use the photovoltaic frame to install the photovoltaic panel body 1 in the designated installation area, and use the tempered film 9 to protect the tempered glass cover 4. Figure 2 As shown, the three incident light rays are respectively incident light rays in the morning, midday and afternoon. When the sunlight irradiates at an angle perpendicular to the horizontal plane, the light intensity is the largest (such as the incident light at noon); and when the sunlight irradiates at an oblique angle, the light intensity will be weakened (such as the incident light in the morning and afternoon). The incident light rays in the morning and afternoon are refracted by the refractive protrusions 3 on the microstructured refractive glass 2, so that the angle between the incident angle and the normal direction of the illuminated surface of the photovoltaic panel body 1 is reduced. When the incident angle is smaller, the light intensity is greater, thereby improving the lighting efficiency of the photovoltaic panel body 1, and reducing the reflection of light by the anti-reflection film 5, the light irradiation efficiency of the photovoltaic panel body 1 can be further improved.

[0045] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
