Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and more specifically, to a photovoltaic module and its processing mold, and photovoltaic equipment. Background Technology

[0002] Foldable photovoltaic modules can be unfolded when in use and folded when not in use, saving a lot of space and thus offering excellent portability.

[0003] Currently, there are three methods for implementing foldable photovoltaic modules: integrated lamination process, sewn-in process, and hinge connection.

[0004] However, the bending area of ​​folded photovoltaic modules using integrated lamination technology becomes brittle at low temperatures, making them difficult to open and close. Sewing and wrapping processes are not effective at waterproofing, and hinge connections also have the problems of complex structure and high cost. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the related art.

[0006] Therefore, the first aspect of this application is to propose a photovoltaic module.

[0007] The second aspect of this application is to provide a processing mold.

[0008] The third aspect of this application is to propose a photovoltaic device.

[0009] In view of the above, according to the first aspect of this application, a photovoltaic module is proposed, comprising: multiple photovoltaic panels, each photovoltaic panel having connecting wires; the multiple photovoltaic panels being connected sequentially by the connecting wires; a connector disposed between two adjacent photovoltaic panels; the connector comprising a first connecting area, a bending area, and a second connecting area; the first connecting area, the bending area, and the second connecting area being arranged sequentially, the first connecting area being connected to one of the two adjacent photovoltaic panels, and the second connecting area being connected to the other of the two adjacent photovoltaic panels; the bending area being made of a flexible material, and the thickness of the bending area being less than the thickness of the first connecting area and the second connecting area, respectively.

[0010] In the above technical solution, by designing a flexible bending area, the photovoltaic module can be folded up when not in use, thereby greatly saving storage and transportation space and improving the portability and practicality of the photovoltaic module; furthermore, the thickness of the bending area is smaller than that of the first connection area and the second connection area, which helps to reduce the resistance during folding, thereby improving the smoothness and fluency of folding.

[0011] In some technical solutions, the first connection area, the second connection area, and the bending area may optionally be made of the same material.

[0012] In practical applications, the first connection area, the second connection area, and the bending area are made of the same material, i.e., the same flexible material. This ensures that all connectors use the same flexible material, making the manufacturing process more uniform and simplified.

[0013] In some technical solutions, optionally, the first connection area and the first connection area respectively wrap around the side of the corresponding photovoltaic panel.

[0014] In the above technical solution, by wrapping the side of the photovoltaic panel with the connection area, a relatively closed sealed space is formed, which can effectively prevent moisture, dust and other pollutants from entering the interior of the photovoltaic module through the connection area, so as to ensure that the photovoltaic module has good waterproof and dustproof performance during use.

[0015] In some technical solutions, the connector may optionally enclose the connecting wire.

[0016] Connecting wires, as a crucial component for transmitting electrical energy in photovoltaic modules, are susceptible to external environmental influences, which can reduce their conductivity and, in severe cases, lead to short circuits or open circuits. Encasing the connecting wires with connectors protects them and further enhances the waterproof performance of the photovoltaic modules. Furthermore, the connectors are made of silicone, which possesses excellent insulation properties, ensuring stable insulation of the connecting wires during power transmission, thereby improving the safety and reliability of the photovoltaic modules.

[0017] In some technical solutions, the connecting wires can optionally be positioned on the back side of the photovoltaic panel. This design avoids the connecting wires casting shadows under sunlight, thereby reducing the impact of shading on the photovoltaic panel's power generation efficiency.

[0018] In some technical solutions, the connecting wires may optionally include busbars, flexible cables, or braided copper tape.

[0019] In some technical solutions, the photovoltaic module may optionally include a handle; the photovoltaic panel has a hollowed-out groove, and when the photovoltaic module is in a folded state, the hollowed-out grooves on multiple photovoltaic panels are aligned with each other to form a handle.

[0020] In the above technical solution, the design of the handle allows users to easily carry and move the photovoltaic modules after folding. Furthermore, the handle is formed by aligning the perforated slots on the photovoltaic panel, utilizing only the structural space of the panel itself without adding extra volume, allowing the photovoltaic modules to maintain a compact structure for easy carrying and storage. Finally, the perforated slot design eliminates the need for additional connections or assembly, thus facilitating processing.

[0021] In some technical solutions, the flexible material may optionally include silicone.

[0022] Silicone has good flexibility and impact resistance, which gives photovoltaic modules a long service life. In addition, silicone material can be used in a temperature range of -60℃ to 200℃ and will not become brittle at low temperatures.

[0023] In some technical solutions, optionally, the first connection area and the second connection area are bonded to the corresponding photovoltaic panels, respectively.

[0024] By using adhesive bonding, the adhesive can fill the tiny gaps between the joint areas, thereby further improving the waterproof performance of photovoltaic modules.

[0025] In some technical solutions, the photovoltaic panel optionally includes: a front barrier layer, a first encapsulant layer, a battery layer, a second encapsulant layer, and a rear barrier layer stacked sequentially from top to bottom.

[0026] In some technical solutions, the photovoltaic panel may optionally include a wear-resistant layer; the wear-resistant layer is disposed above the front barrier layer, and a third encapsulant layer is disposed between the wear-resistant layer and the front barrier layer; and / or; the wear-resistant layer is disposed below the rear barrier layer, and a fourth encapsulant layer is disposed between the wear-resistant layer and the rear barrier layer.

[0027] By introducing a wear-resistant layer, the wear resistance and scratch resistance of the photovoltaic panel surface can be improved, thereby extending its service life and maintaining high power generation efficiency.

[0028] In some technical solutions, the photovoltaic panel may optionally include a reinforcement layer disposed between the first encapsulant layer and the front barrier layer; a fifth encapsulant layer is disposed between the reinforcement layer and the front barrier layer.

[0029] By adding a reinforcing layer, the overall structural strength of the photovoltaic panel can be further improved, providing a strong guarantee for the long-term stable operation of the photovoltaic panel.

[0030] According to the second aspect of this application, this application proposes a processing mold for processing the photovoltaic module proposed in the first aspect of this application; thereby, the photovoltaic module processed by the processing mold has all the beneficial effects of any of the above technical solutions, which will not be repeated here.

[0031] Specifically, the processing mold includes: an upper module, which includes a first end face, a first receiving groove, a first groove, and a first protrusion; the first receiving groove is disposed on the first end face and extends along the array direction of multiple photovoltaic panels to penetrate the first end face; the first protrusion is disposed in the first receiving groove, and the first groove is disposed in the first receiving groove and located on both sides of the first protrusion; and a lower module, which includes a second end face, a second receiving groove, a second groove, and a second protrusion; the second receiving groove is disposed on the second end face and extends along the array direction of multiple photovoltaic panels to penetrate the second end face; the second protrusion is disposed in the second receiving groove, and the second groove is disposed in the second receiving groove and located on both sides of the second protrusion; when the upper module and the lower module are molded together, the first receiving groove and the second receiving groove are connected to form a receiving cavity, the thickness of which is the same as the thickness of the photovoltaic panel; the first groove and the second groove are connected to form a connecting area forming cavity, and the first protrusion and the second protrusion are opposite to each other to form a bending area forming cavity.

[0032] According to a third aspect of this application, a photovoltaic device is proposed, comprising the photovoltaic module proposed in the first aspect. Therefore, this photovoltaic device possesses all the beneficial effects of any of the aforementioned technical solutions, which will not be elaborated further.

Detailed Implementation

[0051] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0052] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0053] The following is combined with Figures 1 to 13 The photovoltaic modules, their processing molds, and photovoltaic equipment provided in this application will be described in detail through specific embodiments and application scenarios.

[0054] Reference Figures 1 to 3 The embodiments of this application provide a photovoltaic module 100, including: multiple photovoltaic panels 110 and connectors 120.

[0055] Reference Figure 1 , Figure 2 and Figure 3 Specifically, the photovoltaic panel 110 is provided with connecting lines 130, and multiple photovoltaic panels 110 are connected sequentially through the connecting lines 130. A connector 120 is disposed between two adjacent photovoltaic panels 110; the connector 120 includes a first connecting area 121, a bending area 122, and a second connecting area 123 arranged sequentially; wherein the first connecting area 121 is connected to one of the two adjacent photovoltaic panels 110, and the second connecting area 123 is connected to the other; the bending area 122 is made of flexible material, and the thickness of the bending area 122 is less than the thickness of the first connecting area 121 and the second connecting area 123, respectively.

[0056] In the above embodiments, by designing a flexible bending area 122, the photovoltaic module 100 can be folded up when not in use, thereby greatly saving storage and transportation space and improving the portability and practicality of the photovoltaic module 100; furthermore, the thickness of the bending area 122 is less than the thickness of the first connection area 121 and the second connection area 123, which helps to reduce the resistance during folding, thereby improving the smoothness and fluency of folding.

[0057] In the above embodiments, no special requirements are placed on the connecting wire 130, and any known material with good conductivity can be selected. Exemplarily, the connecting wire 130 includes a busbar, a flexible cable, or a braided copper tape.

[0058] In the above embodiments, no special requirements are placed on the flexible material; any known material with high strength and weather resistance can be selected. For example, the flexible material includes silicone or rubber. Silicone has good flexibility and impact resistance, giving the photovoltaic module 100 a long opening and closing lifespan. Furthermore, silicone is suitable for a temperature range of -60℃ to 200℃ and does not become brittle at low temperatures.

[0059] In some embodiments, the first connecting area 121, the second connecting area 123, and the bending area 122 are made of the same material, that is, they are made of the same flexible material. In this way, the connectors 120 all use the same flexible material, making the processing more uniform and simplified.

[0060] In some embodiments, the first connection area 121 and the second connection area 123 respectively wrap around the side of the corresponding photovoltaic panel 110. By wrapping the side of the photovoltaic panel 110 with the connection area, a relatively closed sealed space is formed, which can effectively prevent moisture, dust and other pollutants from entering the interior of the photovoltaic module 110 through the connection area, thereby ensuring that the photovoltaic module 100 has good waterproof and dustproof performance during use.

[0061] In practical applications, connector 120 also encloses connecting wire 130. Connecting wire 130, as a crucial component for transmitting electrical energy in photovoltaic module 100, is susceptible to external environmental factors (such as moisture erosion and dust accumulation), which can reduce its conductivity and, in severe cases, even lead to short circuits or open circuits. In this embodiment, enclosing connecting wire 130 with connector 120 protects it and further improves the waterproof performance of photovoltaic module 100. Furthermore, connector 120 is made of silicone, which has excellent insulation properties, ensuring that connecting wire 130 maintains stable insulation performance during electrical energy transmission, thereby enhancing the safety and reliability of photovoltaic module 100.

[0062] In the above embodiment, the first connection area 121 and the second connection area 123 are respectively bonded to the corresponding photovoltaic panel 110. By bonding, the adhesive can fill the tiny gaps between the connection areas, thereby further improving the waterproof performance of the photovoltaic module 100.

[0063] Reference Figure 3 and Figure 4 In some embodiments, the connecting wire 130 is disposed on the back surface 113 of the photovoltaic panel 110. Placing the connecting wire 130 on the back surface of the photovoltaic panel 110 can prevent the connecting wire 130 from casting a shadow under sunlight, thereby reducing the impact of shadow shading on the power generation efficiency of the photovoltaic panel 110.

[0064] Reference Figure 1 In some embodiments, the photovoltaic module 100 also includes a handle 140. The photovoltaic panel 110 is provided with a hollowed-out groove 111; when the photovoltaic module 100 is in a folded state, the hollowed-out grooves 111 on multiple photovoltaic panels 110 are aligned with each other to form the handle 140.

[0065] In the above embodiment, by designing the handle 140, the user can easily carry and move the photovoltaic module 100 after folding. Simultaneously, the handle 140 is formed by aligning the hollow slots 111 on the photovoltaic panel 110, utilizing only the structural space of the photovoltaic panel 110 itself without adding extra volume, allowing the photovoltaic module 100 to maintain a compact structure, facilitating carrying and storage. Finally, the design of the hollow slots 111 eliminates the need for additional connections or assembly, thus facilitating processing.

[0066] Reference Figure 4 and Figure 9 In some embodiments, the photovoltaic panel 110 includes a front barrier layer 1100, a first encapsulant layer 1101, a battery layer 1102, a second encapsulant layer 1103, and a rear barrier layer 1104, which are stacked sequentially from top to bottom (from the light-receiving surface 112 toward the backlight surface 113).

[0067] In the above embodiments, the front barrier layer 1100 and the rear barrier layer 1104 are made of the same material, PET. The first adhesive film layer 1101 and the second adhesive film layer 1103 are made of the same material.

[0068] In the above embodiments, there are no special requirements for the materials of the front barrier layer 1100 and the rear barrier layer 1104; any known material with good water vapor barrier properties can be selected. For example, the front barrier layer 1100 and the rear barrier layer 1104 may be made of PET (Polyethylene terephthalate), CPC (Coating-PET-Coating), or glass fiber composite materials.

[0069] In the above embodiments, there are no special requirements for the materials of the first adhesive layer 1101 and the second adhesive layer 1103; any known material with good adhesive properties can be selected. For example, the first adhesive layer 1101 and the second adhesive layer 1103 may be selected from POE (Polyolefin Elastomer), EVA (Ethylene-Vinyl Acetate), EPE (EVA / POE / EVA co-extrusion), or PVB (Polyvinyl Butyral).

[0070] Reference Figure 10 and Figure 11In some embodiments, the photovoltaic panel 110 further includes a wear-resistant layer 1105. The wear-resistant layer 1105 is disposed above the front barrier layer 1100, and a third adhesive film layer 1106 is provided between the wear-resistant layer 1105 and the front barrier layer 1100; and / or; the wear-resistant layer 1105 is disposed below the rear barrier layer 1104, and a fourth adhesive film layer 1107 is provided between the wear-resistant layer 1105 and the rear barrier layer 1104.

[0071] In the above embodiments, by introducing the wear-resistant layer 1105, the wear resistance and scratch resistance of the photovoltaic panel 110 surface can be improved, thereby extending its service life and maintaining high power generation efficiency. In this embodiment, there are no special requirements for the material of the wear-resistant layer 1105; any known material with good wear resistance and strength can be selected. For example, the wear-resistant layer 1105 is selected from PVDF (Polyvinylidene fluoride), PVF (Polyvinyl Fluoride), and ETFE (Ethylene-Tetrafluoroethylene).

[0072] In practical applications, the materials of the third adhesive layer 1106 and the fourth adhesive layer 1107 are the same as those of the first adhesive layer 1101, which facilitates processing.

[0073] Reference Figure 12 In some embodiments, the photovoltaic panel 110 further includes a reinforcement layer 1108. The reinforcement layer 1108 is disposed between the first adhesive film layer 1101 and the front barrier layer 1100; a fifth adhesive film layer 1109 is disposed between the reinforcement layer 1108 and the front barrier layer 1100.

[0074] In the above embodiments, by adding a reinforcing layer 1108, the overall structural strength of the photovoltaic panel 110 can be further improved, providing a strong guarantee for the long-term stable operation of the photovoltaic panel 110.

[0075] The reinforcing layer 1108 is made of fiberglass prepreg or other fiber composite materials. Fiberglass prepreg is a composite material made of glass fiber as the base material, which is impregnated with resin and other adhesives after processing. It has good mechanical strength, anti-aging properties, and corrosion resistance; at the same time, fiberglass prepreg also has a certain degree of flexibility, which can adapt to various deformations of the photovoltaic panel 110 during manufacturing and installation.

[0076] In practical applications, the fifth adhesive layer 1109 and the first adhesive layer 1101 are made of the same material. Using adhesive layers of the same material facilitates processing.

[0077] Reference Figures 5 to 8In some embodiments, this application also provides a processing mold 200 for processing the photovoltaic module 100 provided in any of the above embodiments. The photovoltaic module processed by this processing mold thus possesses all the beneficial effects of any of the above embodiments, which will not be elaborated further here.

[0078] Reference Figure 1 , Figure 5 , Figure 6 and Figure 8 Specifically, the processing mold 200 includes an upper module 210 and a lower module 220. The upper module 210 includes a first end face 211, a first receiving groove 212, a first groove 213, and a first protrusion 214; the first receiving groove 212 is disposed on the first end face 211 and along the array direction of the multiple photovoltaic panels 110. Figure 1 The first protrusion 214 is disposed in the first receiving groove 212, and the first groove 213 is disposed in the first receiving groove 212 and located on both sides of the first protrusion 214. (The direction indicated by B in the middle) extends to penetrate the first end face 211; the first protrusion 214 is disposed in the first receiving groove 212 and located on both sides of the first protrusion 214. The lower module 220 includes a second end face 221, a second receiving groove 222, a second groove 223, and a second protrusion 224. The second receiving groove 222 is disposed on the second end face 221 and extends along the array direction of the multiple photovoltaic panels 110 to penetrate the second end face 221. The second protrusion 224 is disposed in the second receiving groove 222, and the second groove 223 is disposed in the second receiving groove 222 and located on both sides of the second protrusion 224. When the upper module 210 and the lower module 220 are molded together, the first receiving groove 212 and the second receiving groove 222 are connected to form a receiving cavity 230, and the thickness of the receiving cavity 230 is the same as the thickness of the photovoltaic panel 110. The first groove 213 and the second groove 223 are connected to form a connecting area forming cavity 240, and the first protrusion 214 and the second protrusion 224 are opposite to form a bending area forming cavity 250.
