Description

Technical Field

[0001] The utility model relates to the technical field of solar panels, and particularly relates to a high-strength solar panel. Background Art

[0002] Traditional solar panels use tempered glass as the panel, which has good impact resistance and weather resistance, but is heavy, large in size, and non-bendable, and is not suitable for installation on curved surfaces and mounting surfaces with limited bearing capacity. Therefore, flexible panels have been introduced in the industry, but most of them solve the risk of power attenuation caused by cell microcracks by using imported cells. Some manufacturers use transparent TPT or PET and other materials to replace the tempered glass panel. The flexible panels made with this structure have poor anti-microcrack ability, so the power quickly decays due to microcracks during use. In particular, in scenarios such as RVs, yachts, and curved buildings, the working conditions are complex, and the conventional flexible panels will cause cell microcracks due to vibration and bending after being used for a period of time, resulting in a serious decline in power generation. For this reason, a high-strength solar panel is proposed. Summary of the Utility Model

[0025] Embodiment

[0026] After improvement, we use anti-tensile fiber materials. On the basis of conventional materials such as EVA and PET / TPT, a layer of fiber material is added to both the front and back sides of the battery cells. After lamination, the multi-layer materials are fused into a whole. In addition to normal power generation, the product also has good tensile strength. After being bent and squeezed greatly, the battery cells will not show large-area hidden cracks, so there will be no significant power attenuation caused by hidden cracks in the battery cells. The specific solution is as follows:

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution: a high-strength solar panel, including a battery panel body 1. The battery panel body 1 includes battery cells 2, a first surface layer structure and a second surface layer structure. The first surface layer structure and the second surface layer structure are respectively arranged on both side surfaces of the battery cells 2. A through hole 4 is provided on the side of the battery panel body 1. A wiring terminal 3 electrically connected to the battery cells 2 is provided on the back of the battery panel body 1 to facilitate the output of electric energy to the outside.

[0028] Both the first surface layer structure and the second surface layer structure include a fiber material layer 8 and two EVA layers 9. The fiber material can be a fiberglass cloth or a composite material obtained by coating and infiltrating the fiberglass cloth with components such as epoxy resin. The two EVA layers 9 are respectively fixed on both sides of the fiber material layer 8. One side of one EVA layer 9 away from the fiber material layer 8 is fixedly connected to the battery cells 2. After adding the fiber material, through lamination, the multi-layer materials are fused into a whole, and the overall strength and toughness are greatly improved. During the production, turnover, transportation and use processes, the occurrence of hidden cracks in the battery cells can be effectively avoided, so as to ensure the continuous and stable operation of the solar panel.

[0029] The first surface layer structure further includes a first surface layer 10. One side surface of the first surface layer 10 is fixedly connected to one side surface of the other EVA layer 9 in the first surface layer structure;

[0030] The second surface layer structure further includes a second surface layer 11. One side surface of the second surface layer 11 is fixedly connected to one side surface of the other EVA layer 9 in the second surface layer structure.

[0031] The first surface layer 10 can be selected from the PET layer among the PET layer, the TPT layer and the ETFE layer.

[0032] The second surface layer 11 can be selected from the ETFE layer among the PET layer and the TPT layer.

[0033] In order to make the anchoring more stable and prevent wear, a first end cap 5 and a second end cap 6 are respectively inserted into both ends of the through hole 4. The first end cap 5 is threadedly connected to the second end cap 6. Through the threaded connection method, the first end cap 5 and the second end cap 6 can be firmly fixed on the battery panel body 1 after connection to avoid falling off. In order to prevent the anchoring nail or other anchor fittings from wearing against the inner wall of the through hole 4, an inner cylinder 7 is rotatably connected inside the first end cap 5. By passing the anchoring nail through the rotatable inner cylinder 7, the anchoring nail will not directly wear against the through hole, and the wear between the anchoring nail and the inner cylinder 7 is reduced, thereby effectively improving the service life of the battery panel body 1.

[0034] In order to enable the inner cylinder 7 to rotate inside the first end cap 5, the first end cap 5 is provided with a circular hole, and an annular groove is provided inside the circular hole. An annular protrusion that slidably engages in the annular groove is provided on the outer side of the inner cylinder 7. This enables the inner cylinder 7 to rotate smoothly under the cooperation of the annular groove and the annular protrusion.

[0035] Particularly, in scenarios such as RVs, yachts, and curved buildings, the working conditions are complex. After using a conventional flexible panel for a period of time, the battery chips will be invisibly cracked due to vibration and bending, resulting in a serious decline in power generation. Under the same working conditions, after adding fiber materials to this high-strength solar panel and through lamination, the strength after the integration of multiple layers of materials into a whole is greatly improved compared to the conventional flexible panel. It can effectively resist vibration and bending stress, so it has more stable performance, is more durable, and its service life is greatly extended.
