The photovoltaic module is arranged on a metal roof; one end of the clamping assembly is connected to the metal roof, and the other end is connected to the photovoltaic module. The photovoltaic module is fixed on the metal roof through the clamping assembly.

[0029] When the photovoltaic module is installed on a corner bead type metal roof, the existing installation method is to first install a guide rail on the metal roof and then install the photovoltaic module on the guide rail.

[0055] Embodiment

[0056] As Figures 1 to 9 shown, this embodiment provides a photovoltaic module installation structure, including a photovoltaic module 1 and a clamping assembly 2. The photovoltaic module 1 is arranged on a metal roof 100; one end of the clamping assembly 2 is connected to the metal roof 100, and the other end is connected to the photovoltaic module 1. The photovoltaic module 1 is fixed on the metal roof 100 through the clamping assembly 2.

[0057] When a photovoltaic module is installed on a corner cleat type metal roof, the existing installation method is to first install a guide rail on the metal roof and then install the photovoltaic module on the guide rail. This installation method requires components such as guide rails to assist in installing the photovoltaic module and cannot directly install the photovoltaic module on the metal roof, which in turn leads to an increase in installation materials and costs, and the installation process is cumbersome. In the embodiment of the present utility model, by providing the photovoltaic module 1 and the clamping assembly 2, the photovoltaic module 1 can be directly installed on the metal roof 100 through the clamping assembly 2, thereby making the installation of the photovoltaic module 1 more convenient and reducing the use of installation materials, saving the installation cost.

[0058] Furthermore, as Figure 2 shown, the photovoltaic module 1 includes a frame 11 and a photovoltaic panel 12. The frame 11 is arranged on the metal roof 100; the photovoltaic panel 12 is arranged on the frame 11 and is adhesively connected to the frame 11 through an adhesive 14. In the embodiment of the present utility model, the existing photovoltaic module has no frame and is relatively thin and light, and is prone to hidden cracks during the installation process. In this embodiment, by providing the frame 11, it can protect the photovoltaic module 1 and prevent the photovoltaic module 1 from being broken, thereby affecting the use of the photovoltaic module 1. In addition, the adhesive 14 can be set as various sealants. The type of setting of the adhesive 14 in this embodiment is not limited, and those skilled in the art can change the type of setting of the adhesive 14 according to actual situations as long as the same technical effects can be achieved.

[0059] In the embodiment of the present utility model, there are four frames 11, and the four frames 11 are sequentially connected to form a frame framework. Of course, the number of frames 11 provided in this embodiment is not limited, and those skilled in the art can change the number of frames 11 provided according to actual situations as long as the same technical effects can be achieved.

[0060] In an embodiment of the present utility model, the photovoltaic panel 12 is composed of a polymer backplane, a polymer adhesive film, a silicon crystal battery, and ultra-thin glass. A layer of polymer adhesive film is provided on each side of the silicon crystal battery, and then the polymer backplane is arranged at the lower end of the lower polymer adhesive film, and the ultra-thin glass is arranged at the upper end of the upper polymer adhesive film, thus forming the photovoltaic panel 12.

[0061] Further, as Figure 3 shown, the frame 11 includes a corner joint cavity 111 and a pressing part groove 112. The corner joint cavity 111 is arranged at one end of the frame 11. The corner joint cavity 111 is adapted to be connected with the corner joint cavity 111 of another frame 11 to form a frame, and the photovoltaic panel 12 is placed in the frame; the pressing part groove 112 is arranged at the other end of the frame 11, and an opening is arranged on the pressing part groove 112, and the clamping assembly 2 is inserted into the opening to be connected with the frame 11.

[0062] Further, a support part 113 is arranged at the top of the corner joint cavity 111 and the pressing part groove 112. The photovoltaic panel 12 is placed on the support part 113, and the support part 113 is connected with the photovoltaic panel 12 through the adhesive part 14. A limiting part 114 is arranged on one side of the support part 113, and the top of the limiting part 114 is lower than the upper surface of the photovoltaic panel 12. In an embodiment of the present utility model, by setting the top of the limiting part 114 lower than the upper surface of the photovoltaic panel 12, it is possible to prevent dust accumulation at the connection between the limiting part 114 and the photovoltaic panel 12, thereby affecting the power generation efficiency of the photovoltaic module 1.

[0063] Further, an overflow glue groove 115 is arranged at the connection between the support part 113 and the limiting part 114. The overflow glue groove 115 is adapted to store the overflowing sealant. In an embodiment of the present utility model, by setting the overflow glue groove 115, the overflowing sealant can be stored in the overflow glue groove 115, thereby avoiding the sealant from polluting the photovoltaic module 1 and reducing the later cleaning work.

[0064] Further, as Figure 4 and Figure 5 shown, the photovoltaic module 1 further includes a reinforcing rib 13. The reinforcing rib 13 is arranged horizontally or vertically on the frame 11 and is connected with the frame 11 through screws. The reinforcing rib 13 is adapted to support the photovoltaic panel 12. In an embodiment of the present utility model, since the existing structure of the photovoltaic module is relatively soft and will deform after long-term use, it is easy to cause water accumulation and dust accumulation, thereby generating a hot spot effect and affecting the power generation efficiency. However, in this embodiment, by setting the reinforcing rib 13, the reinforcing rib 13 can support the photovoltaic panel 12, so that the photovoltaic module 1 will not deform and will not affect the power generation efficiency of the photovoltaic module.

[0065] Furthermore, as Figure 6 shown, a bonding surface 131 and screw holes 132 are provided on the reinforcing rib 13. The bonding surface 131 is connected to the photovoltaic panel 12 through the bonding member 14. The screw holes 132 are arranged inside the reinforcing rib 13, and screws are inserted into the screw holes 132 to be connected to the frame 11. By connecting the bonding surface 131 to the photovoltaic panel 12 and connecting the reinforcing rib 13 to the frame 11 with screws, the connection between the frame 11 and the reinforcing rib 13 can be made more firm. In addition, the cross-section of the reinforcing rib 13 is U-shaped. By setting the reinforcing rib 13 to be U-shaped, the weight of the frame 11 can be further reduced, making the use of the photovoltaic module 1 more convenient.

[0066] Furthermore, as Figure 7 shown, the clamping assembly 2 includes a base 21, a fastener 22, a pressing block 23, an anti-disengagement member 24, a first fastening bolt 25 and a second fastening bolt 26. The base 21 is arranged on the metal roof 100, and the base 21 is provided with a groove 211; one end of the fastener 22 is snapped into the groove 211, and the other end of the fastener 22 is snapped onto the metal roof 100; the pressing block 23 is arranged on the base 21, and both ends are respectively pressed into the pressing part groove 112 through openings; the anti-disengagement member 24 is arranged on the pressing block 23, and both ends are respectively snapped onto the photovoltaic panel 12; the first fastening bolt 25 passes through the base 21 and abuts against the fastener 22, and the first fastening bolt 25 is adapted to lock the clamping assembly 2 and the metal roof 100; the second fastening bolt 26 passes through the base 21, the pressing block 23 and the anti-disengagement member 24, and the base 21, the pressing block 23 and the anti-disengagement member 24 are connected through the second fastening bolt 26.

[0067] As Figure 8 and Figure 9 shown, when the clamping assembly 2 needs to be installed on the metal roof 100, first, the base 21, the pressing block 23 and the anti-disengagement member 24 are connected through the second fastening bolt 26, then the fastener 22 is connected to the groove 211, then the base 21 and the fastener 22 are snapped onto the angled part of the metal roof 100, and then the first fastening bolt 25 is threadedly connected to the base 21. By rotating the first fastening bolt 25, the base 21 and the fastener 22 are respectively snapped onto the angled part of the metal roof 100 to complete the installation of the clamping assembly 2.

[0068] Further, a threaded hole 212 is provided on the side wall of the base 21. The first fastening bolt 25 passes through the threaded hole 212 and abuts against the fastener 22. The first fastening bolt 25 is adapted to lock the clamping assembly 2 and the metal roof 100. When it is necessary to lock the clamping assembly 2 and the angled portion of the metal roof 100, by rotating the first fastening bolt 25, the fastener 22 abuts against the angled portion of the metal roof 100. Continuing to rotate the first fastening bolt 25 causes the base 21 to be clamped to the angled portion of the metal roof 100, thereby completing the clamping of the clamping assembly 2 and the angled portion of the metal roof 100.

[0069] Further, through holes are provided at corresponding positions on the top of the base 21, the pressing block 23, and the anti - detachment member 24. The second fastening bolt 26 passes through the through holes to connect the base 21, the pressing block 23, and the anti - detachment member 24. When assembling the clamping assembly 2, first align the through holes on the top of the base 21, the through holes of the pressing block 23, and the through holes of the anti - detachment member 24. Then pass the second fastening bolt 26 through the through holes of the base 21, the pressing block 23, and the anti - detachment member 24. Then screw the nut onto the second fastening bolt 26 to connect the base 21, the pressing block 23, and the anti - detachment member 24. Then install the fastener 22 in the groove 211 to complete the assembly of the clamping assembly 2.

[0070] In the embodiment of the present utility model, a plurality of photovoltaic modules 1 are installed on the metal roof 100, and the plurality of photovoltaic modules 1 are sequentially connected through the clamping assemblies 2 respectively, thereby forming a photovoltaic power generation system. Of course, the number of the photovoltaic modules 1 provided in this embodiment is not limited. Those skilled in the art can change the number of the photovoltaic modules 1 according to actual situations as long as the same technical effects can be achieved.

[0071] The specific installation process of the photovoltaic module installation structure provided by the present utility model is as follows:

[0072] First, connect the four frames 11 in sequence to form a framework, then connect the reinforcing ribs 13 to the frames 11 through screws, and then paste the photovoltaic panels 12 on the supporting parts 113 and the pasting surfaces 131 through the pasting parts 14 to form the photovoltaic module 1. Then, install the base 21 on the corner bead part of the metal roof 100, and then pass the first fastening bolt 25 through the threaded hole 212 to abut against the fastener 22. Rotate the first fastening bolt 25 to make the base 21 and the fastener 22 respectively snap onto the corner bead part of the metal roof 100. At this time, the clamping assembly 2 is locked with the metal roof 100. Then, install the photovoltaic module 1 on the metal roof 100. Finally, sleeved the through hole of the pressing block 23 onto the second fastening bolt 26, and at the same time make the pressing block 23 snap into the pressing part groove 112. Then, sleeved the through hole of the anti-disengagement part 24 onto the second fastening bolt 26, and at the same time make the anti-disengagement part 24 snap onto the photovoltaic module 1. Then, screw the nut onto the second fastening bolt 26 to lock the clamping assembly 2 with the photovoltaic module 1, thus completing the installation process of the photovoltaic module 1.

[0073] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
