[0002] With the depletion of fossil energy and the improvement of environmental protection, solar power station systems constructed using photovoltaic modules are becoming more and more popular.

[0003] Among the existing methods for fixing flexible photovoltaic module power stations, the main method is to stick the flexible thin-film photovoltaic modules on flat surfaces such as metal roof panels or concrete surfaces through adhesive strips. This method of fixing the modules with the back of the modules completely glued is limited by the installation environment and is mainly used on building surfaces that can provide large areas for direct gluing or large areas for fixing metal back panels, such as metal roof distributed projects, where butyl tape and structural adhesive are glued on the roof floor to fix the flexible modules.

[0004] However, this method is not safe for fixing photovoltaic modules. The adhesive fixing method may cause damage to the modules in windy and rainy weather, which may easily lead to leakage. If the fixing is not firm, the flexible modules may bend easily, which reduces the service life of the flexible modules. Utility Model Content

[0031] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 It is a schematic diagram of the structure of a solar device 100 in one embodiment of the utility model; Figure 2 yes Figure 1 A schematic structural diagram of the solar device 100 from another perspective is shown; Figure 3 yes Figure 1 The solar device 100 is shown in a side view. The embodiment of the present application provides a solar device 100, comprising a corrugated metal plate 1, a plurality of metal square tubes 2, and a plurality of solar cells 3; the corrugated metal plate 1 comprises crests and troughs arranged alternately in sequence; the metal square tubes 2 are mounted and fixed on the crests of the corrugated metal plate 1, and the plurality of metal square tubes 2 are arranged at intervals; and the plurality of solar cells 3 are arranged in sequence on a side of the metal square tubes 2 away from the corrugated metal plate 1.

[0032] The embodiment of the utility model provides a solar device 100, which fixes the metal square tube 2 on the wave crest of the corrugated metal plate 1, and the plurality of metal square tubes 2 are arranged at intervals, so that the battery cell 3 is arranged on the fixed metal square tube 2, and the battery cell 3 can be well supported by the metal square tube. In addition, the metal square tube 2 is relatively flat, which is conducive to the fixation of the battery cell 3 and prevents the battery cell 3 from being deformed and damaged. Through the cooperation of the corrugated metal plate 1 and the metal square tube 2, the battery cell 3 of the solar device 100 is fixed more firmly and has a longer service life.

[0033] In the embodiment of the present application, the cell 3 may be a solar panel. For example, the cell 3 may be a composite cell 3 including a central cell 3, a prepreg layer, a resin layer, and a fluoroplastic layer. The interlayers may be bonded by an adhesive. The corrugated metal plate 1 may be a metal plate with a regular wave shape or an irregular wave shape. For example, it may be a color steel tile with a regular wave shape. The crest and trough of the corrugated metal plate 1 are respectively the highest point and the lowest point of the "wave" of the corrugated metal plate 1 after the corrugated metal plate 1 is fixed.

[0034] In some embodiments, multiple cells 3 are connected in series. The series connection between cells 3 can reduce the use of cables. Only a few cables are needed to connect to the inverter, which reduces the power loss caused by the cables and improves the power generation efficiency of the power station. Cells 3 absorb solar energy and convert it into electrical energy by connecting in series, and then convert the direct current generated by the cells 3 into alternating current through the inverter to provide electrical energy to the electrical appliances.

[0035] In some embodiments, the two ends of the battery cell 3 are fixed between two adjacent metal square tubes 2. The metal square tubes 2 are used as the support points for laying the battery cell 3. This method increases the force-bearing area of ​​the battery cell 3, and the structural fixation is also safer, which not only avoids the wear of the battery cell 3, prolongs the life of the battery cell 3, but also avoids the risk of leakage.

[0036] In some embodiments, the metal square tube 2 may be an aluminum square tube.

[0037] In some embodiments, the two ends of the battery cell 3 are connected to at least one metal square tube 2. The metal square tube 2 is provided in the middle of the battery cell 3 for support, which can further increase the force-bearing area of ​​the battery cell 3, make the structural fixation of the battery cell 3 safer, further extend the life of the battery cell 3, and avoid the risk of leakage.

[0038] In some embodiments, the battery cell 3 is fixedly connected to the metal square tube 2 by an adhesive, so that the battery cell 3 and the metal square tube 2 are firmly attached to each other to prevent the battery cell 3 from being damaged by external forces, such as wind, etc. Exemplarily, the adhesive may be a structural adhesive.

[0039] In some embodiments, the solar device 100 further includes a fastener 4; one end of the fastener 4 is fixed to the corrugated metal plate 1, and the other end is fixedly connected to the metal square tube 2. The metal square tube 2 and the corrugated metal plate 1 can be fastened by the fastener 4, so that the metal square tube 2 is fixed more firmly, and then the battery cell 3 is fixed more firmly. Exemplarily, the fastener 4 can be an anchor bolt; by using the anchor bolt on the corrugated metal plate 1, the metal square tube 2 is easier to install, disassemble, replace, maintain, and is more firmly installed.

[0040] In some embodiments, both ends of the metal square tube 2 are fixedly connected by fasteners 4. Both ends of the metal square tube 2 are fastened by fasteners 4, so that the fixation of the metal square tube 2 is more secure. In other embodiments, in order to further enhance the firmness of the metal square tube 2, a fastener 4 can be added to the middle of the metal square tube 2 for fastening.

[0041] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 4 yes Figure 3 The enlarged structural diagram of part A in the figure. The connection of the two connected metal square tubes 2 is fixedly connected by the same fastener 4. The connection of the two metal square tubes 2 uses the same anchor bolt, which can reduce the use of anchor bolts, save installation costs, and greatly improve the output power of the solar device 100.

[0042] In some embodiments, the middle position of the fastener 4 may include a protrusion, and the protrusion is at a certain distance from the end connected to the corrugated metal plate 1, so as to ensure that after the metal square tube 2 is fastened and connected to the fastener 4, it can have a certain distance between the troughs of the corrugated metal plate 1, which is convenient for the heat dissipation of the battery cell 3. After the position of the corrugated metal plate 1 is installed, the fastener 4 is installed to the appropriate position on the corrugated metal plate 1, and one end of the two adjacent metal square tubes 2 is respectively set on the fastener, and then one end of the two metal square tubes 2 is fixed by bolts, and then the other end of the metal square tube 2 is fixed. Finally, the battery cell 3 is arranged and installed according to the power station sequence by an adhesive, and its lead wires are connected in series to generate electricity. Thereby, the battery cell 3 of the solar device 100 is fixed more firmly and has a longer service life. At the same time, the power efficiency and output power of the solar device 100 are also greatly improved.

[0043] In some embodiments, an adhesive is provided at the connection between the fastener 4 and the corrugated metal plate 1; the adhesive is used to fix the connection between the fastener 4 and the corrugated metal plate 1; and the adhesive is used to seal the gap at the connection between the fastener 4 and the corrugated metal plate 1. Exemplarily, the adhesive may be a structural adhesive. The connection between the fastener 4 and the corrugated metal plate 1 is bonded by the structural adhesive, which can achieve a good sealing of the gap at the connection while fastening the connection. Exemplarily, the structural adhesive bonds the anchor bolts and the color steel tile to ensure that the color steel tile is watertight.

[0044] In some embodiments, the distance between the troughs of the corrugated metal plate 1 used by the battery cell 3 is between 40mm and 60mm. The distance between the battery cell 3 and the trough of the corrugated metal plate 1 is 40mm-60mm, which can ensure that the back heat dissipation effect of the battery cell 3 is good, and solve the defect of poor heat dissipation of the original battery cell 3. Since the adjacent metal square tubes 2 share a fastener 4, when the metal square tube 2 is fixed by the fastener 4, the distance between the metal square tube 2 and the trough of the corrugated metal plate 1 can be different or the same. Exemplarily, when two adjacent metal square tubes 2 need to be stacked and then fastened, their heights from the corrugated metal plate 1 are different; when the fastener 4 is located in the middle of one end of the two metal square tubes 2 that are close to each other, for example, when the edges of the two metal square tubes 2 are tightened by tightening the anchor bolts, the heights of the two metal square tubes 2 can be the same. It is necessary to comprehensively consider the fixed height of the metal square tube 2 and the structural strength and stability of the metal square tube 2.

[0045] In some embodiments, the distance between the battery cell 3 and the trough of the corrugated metal plate 1 is 40 mm, 42 mm, 45 mm, 50 mm, 55 mm, 58 mm, or 60 mm, etc. For example, the distance between two adjacent metal square tubes 2 and the trough of the corrugated metal plate 1 can be 50 mm; or the distance between one metal square tube 2 and the trough of the corrugated metal plate 1 is 45 mm, and the distance between the other metal square tube 2 and the trough of the corrugated metal plate 1 is 50 mm.

[0046] The solar device 100 of the present application is a solar device 100 that is easy to install, easy to disassemble, easy to replace, and easy to maintain. It has the characteristics of simple installation and wide application range. It is a technology that uses battery cells 3 to generate electricity in series. For example, the battery cell 3 can be a monocrystalline silicon solar cell 3. The main principle and function of the solar device 100 is that the monocrystalline silicon solar cell 3 is formed into a flexible component through a special lamination of an ethylene-tetrafluoroethylene copolymer layer and a prepreg material layer. The monocrystalline silicon solar flexible component is fixed on the color steel tile with anchor bolts and aluminum square tubes, and absorbs solar energy in series and converts solar energy into electrical energy. Then, the direct current generated by the inverter is converted into alternating current to provide electrical energy to the electrical appliance. The flexible component has the characteristics of being light, thin, soft, bendable, not broken, strong and durable, and can be widely used in various environments, such as flat roofs, color steel tile roofs, etc., and is suitable for power station systems of various capacities, such as large-scale centralized power stations, various distributed power stations, household systems, etc. Moreover, the installation of this solar device 100 is simple and flexible, and the construction efficiency is extremely high; the material consumption of this solar device 100 is also very small, and the cost is very low.
