[0046] Figure 1 It is a schematic diagram of a photovoltaic roof system according to some embodiments of the present application.

[0047] One or more embodiments of the present application disclose a photovoltaic roof system. Figures 1 to 5The photovoltaic roof system includes: a photovoltaic module 90, a mounting module, a fixing module 10 and a tile 60. The mounting module is arranged on both sides of the photovoltaic module 90, and the mounting module includes a mounting frame 50, and the mounting frame 50 includes a frame body 51 and a receiving portion 52, and the receiving portion 52 is suitable for installing the photovoltaic module 90. The fixing module 10 is connected to the frame body 51, and the frame body 51 extends from the receiving portion 52 to the fixing module 10. The fixing module 10 is provided with a connecting hole 11 and a receiving cavity 12, and the connecting hole 11 faces the frame body 51. The fixing module 10 is adjustably fixed to the frame body 51 through the connecting hole 11. The tile 60 includes a locking portion 65, and the locking portion 65 is received in the receiving cavity 12 of the fixing module 10, so that the locking portion 65 of the tile 60 and the fixing module 10 are embedded.

[0048] It is understandable that the mounting frame 50 is arranged on both sides of the photovoltaic assembly 90, which is conducive to reducing the wind lifting force on the edge of the photovoltaic assembly 90, so as to improve the wind lifting resistance of the photovoltaic assembly 90. Further, the mounting frame 50 is detachably connected to the tile 60 through the fixing assembly 10, so as to improve the adjustability of the photovoltaic assembly 90 during installation, and to facilitate the removal and replacement of the photovoltaic assembly 90 during later maintenance. Further, the locking portion 65 of the tile 60 extends into the accommodating cavity 12 of the fixing assembly 10, so that the locking portion 65 is located between the mounting frame 50 and the fixing assembly 10. Under the condition of wind lifting force, the locking portion 65 is suitable for counteracting the fixing assembly 10, which is conducive to increasing the force bearing area of ​​the tile 60 and the fixing assembly 10, thereby improving the wind lifting resistance of the photovoltaic roof system. The middle part of the photovoltaic assembly 90 is supported by the supporting portion 63 of the tile 60, that is, the middle area of ​​the photovoltaic assembly 90 is supported, which is conducive to improving the bearing capacity of the photovoltaic roof system, and thus when installing and repairing the photovoltaic roof system, it is convenient for engineers to step on the photovoltaic assembly 90.

[0049] In some embodiments, reference Figure 2 , Figure 3 and Figure 5 The frame body 51 is provided with a through hole 511 and a mounting groove 512. The through hole 511 is opened on the side of the frame body 51. The through hole 511 and the connecting hole 11 are aligned. The frame body 51 and the fixing component 10 are connected by fasteners passing through the through hole 511 and the connecting hole 11. The mounting groove 512 is suitable for partial installation and positioning of the fixing component 10.

[0050] That is, when the fixing assembly 10 is mounted on the mounting frame 50, the connection hole 11 on the fixing assembly 10 is aligned with the through hole 511 on the frame body 51, so that the fixing assembly 10 and the mounting frame 50 can be detachably connected by fasteners. In addition, the locking portion 65 of the tile 60 extends into the accommodating cavity 12 of the fixing assembly 10, so that the fixing assembly 10 can be hooked with the tile 60, and the frame body 51 of the mounting frame 50 is suitable for abutting against the upper surface of the locking portion 65, so that the mounting frame 50 is placed and fixed on the tile 60.

[0051] In at least one embodiment, reference Figure 6 The through hole 511 on the frame body 51 is a long hole extending axially along the frame body 51, and the connecting hole 11 on the fixing component 10 is a circular through hole or a threaded hole. Therefore, when the fixing component 10 is installed on the frame body 51, the position of the fixing component 10 along the axial direction of the frame body 51 can be adjusted, so that the installation of the fixing component 10 is more flexible, which is conducive to reducing the installation difficulty of the fixing component 10 and improving the installation efficiency.

[0052] Further, see Figure 6 A plurality of through holes 511 are arranged at intervals along the axial direction of the frame body 51, which can reduce the influence of the through holes 511 on the structural strength of the mounting frame 50, and can also set a plurality of fixing components 10 at intervals along the axial direction of the mounting frame 50, so that the mounting frame 50 is connected to the tile 60 through the plurality of fixing components 10, which is beneficial to improve the connection strength and connection reliability, and is beneficial to increase the contact area between the fixing components 10 and the tile 60, and is beneficial to improve the wind-resistant ability of the photovoltaic roof system.

[0053] In some embodiments, reference Figure 5 The mounting groove 512 is a C-shaped groove structure. The frame body 51 is provided with a slot section 513. The slot section 513 is located on the opposite side of the through hole 511. The spacing between the slot sections 513 is smaller than the mounting spacing of the mounting groove 512. The receiving portion 52 is provided with a receiving surface 521 and a stop section 522. The receiving surface 521 is suitable for receiving the photovoltaic component 90. The stop section 522 protrudes upward from one end of the receiving portion 52.

[0054] That is, the frame body 51 is C-shaped, so that the installation groove 512 is formed in the middle area of ​​the frame body 51. Furthermore, the notch section 513 and the through hole 511 are located on opposite sides of the installation groove 512, so that the fastener can pass through the notch of the through hole 511 and the installation groove 512 and connect with the connection hole 11 of the fixing assembly 10. The receiving portion 52 is located on the side of the frame body 51 facing the photovoltaic assembly 90. The receiving portion 52 has a receiving surface 521 on the side facing the photovoltaic assembly 90. The receiving surface 521 is used to support the edge of the photovoltaic assembly 90. The stop section 522 protrudes from one side of the receiving surface 521 toward the photovoltaic assembly 90 and extends along the axial direction of the mounting frame 50.

[0055] In some embodiments, reference Figure 5 The photovoltaic roof system further includes an adhesive 101, which is arranged between the receiving surface 521 and the photovoltaic module 90, so that the mounting frame 50 is bonded and fixed to the photovoltaic module 90, and has a buffering effect, which is conducive to avoiding hard contact between the mounting frame 50 and the photovoltaic module 90, thereby reducing the risk of hidden cracks in the photovoltaic module 90. It is understandable that when the adhesive 101 is arranged on the receiving surface 521, the stop section 522 can play an auxiliary positioning role for the adhesive 101, which is conducive to reducing the difficulty of arranging the adhesive 101 on the receiving surface 521, thereby improving the installation efficiency.

[0056] In the related art, frameless photovoltaic modules are bonded to tiles with structural adhesive. This fixing method makes installation and disassembly very difficult, and the bonding quality of the structural adhesive is greatly affected by the on-site environment, which is not conducive to quality control. In addition, due to the large amount of dust during on-site construction, the tiles need to be cleaned before gluing, which easily affects the on-site construction efficiency. During installation, the bonding position of the photovoltaic modules is difficult to control, and it is difficult to disassemble after bonding, and the fault tolerance rate is low.

[0057] In this embodiment, referring to Figure 5 , the mounting frame 50 and the photovoltaic module 90 can be pre-bonded and installed before leaving the factory, so as to control the glue injection to form the adhesive member 101 under a constant temperature and humidity environment, thereby improving the bonding quality and the connection reliability between the photovoltaic module 90 and the mounting frame 50. In addition, the mounting frame 50 and the fixing component 10 are detachably connected by fasteners, and the installation and disassembly operations are simple, which is conducive to reducing the difficulty of disassembling the photovoltaic module 90 during on-site installation and subsequent maintenance and repair.

[0058] It is worth mentioning that the photovoltaic assembly 90 is directly bonded to the mounting frame 50, which helps to avoid setting a photovoltaic frame around the photovoltaic assembly 90, thereby reducing the decrease in power generation caused by dust accumulation.

[0059] In some embodiments, reference Figures 1 to 3The fixing assembly 10 includes a first fixing member 20 and a second fixing member 30. The first fixing member 20 and the second fixing member 30 are disposed on both sides of the photovoltaic assembly 90. Figure 7 The first fixing member 20 is provided with a first connecting hole 211 and a first accommodating cavity 25, referring to Fig.12 The second fixing member 30 is provided with a second connecting hole 311 and a second accommodating cavity 35. The first fixing member 20 is adjustably fixed to the mounting frame 50 on one side of the photovoltaic component 90 through the first connecting hole 211. The second fixing member 30 is adjustably fixed to the mounting frame 50 on the other side of the photovoltaic component 90 through the second connecting hole 311. The openings of the first accommodating cavity 25 and the second accommodating cavity 35 are arranged opposite to each other, so that the locking portions 65 on both sides of the tile 60 are bent and extended toward the first accommodating cavity 25 and the second accommodating cavity 35 respectively and are embedded with each other.

[0060] That is to say, referring to Figure 7 , the two opposite sides of the photovoltaic module 90 are respectively bonded to the mounting frame 50, and the mounting frame 50 on one side is connected to the first fixing member 20 through the first fastener 41. Specifically, the first fastener 41 passes through the through hole 511 on the frame body 51 to be screwed with the first connecting hole 211 of the first fixing member 20, thereby detachably connecting the mounting frame 50 and the first fixing member 20. Similarly, referring to Fig.12 The mounting frame 50 on the other side is connected to the second fixing member 30 through the second fastener 42. Specifically, the second fastener 42 passes through the through hole 511 on the frame body 51 and the second connecting hole 311 on the second fixing member 30, so that the mounting frame 50 and the second fixing member 30 can be detachably connected.

[0061] Further, see Figure 7 and Fig.12 The tile 60 has locking parts 65 on both sides, one of which extends into the first accommodating cavity 25 of the first fixing member 20, so that the locking part 65 is located between the first fixing member 20 and the frame body 51, so that the tile 60 and the first fixing member 20 are hooked. Similarly, the other locking part 65 extends into the second accommodating cavity 35 of the second fixing member 30, so that the locking part 65 is located between the second fixing member 30 and the frame body 51, so that the tile 60 and the second fixing member 30 are hooked, and then the two sides of the photovoltaic assembly 90 are connected to the tile 60 through the mounting frame 50 and the fixing assembly 10.

[0062] Furthermore, the openings of the first accommodating cavity 25 and the second accommodating cavity 35 are arranged relative to each other, so that the two locking parts 65 of the tile 60 are located between the first fixing member 20 and the second fixing member 30, which is conducive to protecting the locking parts 65 through the fixing assembly 10. It is worth mentioning that under the condition of wind lifting force, the photovoltaic assembly 90 tends to be lifted upward and acts on the two locking parts 65 of the tile 60. The two locking parts 65 can decompose the received force into two components in opposite directions, which is conducive to preventing the fixing assembly 10 from being disengaged from the tile 60, and improving the wind lifting resistance of the photovoltaic roof system.

[0063] In some embodiments, reference Fig.17 The tile 60 further includes a body portion 61, and the locking portions 65 are bent and extended from the ends of the body portion 61 toward the accommodating cavity 12 of the fixing assembly 10, so that the locking portions 65 of the tile 60 and the fixing assembly 10 are embedded. Figures 17 to 19 The locking portion 65 is provided with a protruding section 651, a groove 652, a covering section 653 and a locking section 654. The protruding section 651 is bent and protruded from the main body 61 of the tile 60 toward the accommodating cavity 12, so that the protruding section 651 is embedded in the accommodating cavity 12. The covering section 653 is bent to connect the protruding section 651 and the locking section 654. The groove 652 is formed in the covering section 653. At least part of the fixing component 10 forming the accommodating cavity 12 is suitable for being embedded in the groove 652, so that the covering section 653 at least covers part of the first fixing member 20 and / or the second fixing member 30. The ends of two adjacent tiles 60 are suitable for being bent to form the locking section 654.

[0064] Furthermore, the tile 60 also includes a connecting portion 64. Specifically, the main body 61 of the tile 60 is suitable for being placed on a roof, and connecting portions 64 are respectively provided at both ends of the main body 61, and the two connecting portions 64 extend in directions of the photovoltaic assembly 90 away from each other, and the connecting portions 64 are used to support the locking portion 65. The protruding section 651 is bent and protruded from one end of the connecting portion 64 away from the main body 61 toward the accommodating cavity 12 of the fixing assembly 10, so that the protruding section 651 extends into the accommodating cavity 12; further, the covering section 653 is bent back from one end of the protruding section 651 away from the connecting portion 64, so that a groove 652 is formed below the protruding section 651, and at least part of the fixing assembly 10 extends into the groove 652, so that the tile 60 can be hooked with the fixing assembly 10.

[0065] Furthermore, the locking section 654 extends from one end of the covering section 653 away from the protruding section 651 in a direction away from the roof to form the locking section 654. It can be understood that the locking sections 654 of two adjacent tiles 60 are suitable for stacking and bending to form a tile rib 66, so that the two adjacent tiles 60 are connected and fixed.

[0066] In at least one embodiment, reference Fig.17 The tile 60 also has a boss 62 , which protrudes from the middle area of ​​the main body 61 in a direction away from the roof, thereby improving the structural strength of the main body 61 .

[0067] In some embodiments, reference Figures 7 to 11 The first fixing member 20 includes a first main body section 21, a clamping joint 22 and a first extension section 23. The clamping joint 22 expands and protrudes from the first main body section 21 toward the mounting groove 512 of the mounting frame 50. The first connecting hole 211 is opened in the clamping joint 22. The clamping joint 22 is suitable for sliding into the mounting groove 512 and aligning the first connecting hole 211 with the through hole 511 of the mounting frame 50, so that the clamping joint 22 can be adjustably fixed in the mounting groove 512 of the frame body 51. The first extension section 23 extends from the other end of the first main body section 21 relative to the clamping joint 22 toward the locking portion 65 of the tile 60. The first accommodating cavity 25 is formed between the mounting frame 50 and the first extension section 23. The locking portion 65 is embedded in the first accommodating cavity 25 and bent to cover the first extension section 23.

[0068] That is to say, referring to Figure 7 The clamping joint 22 of the first fixing member 20 is adapted to be engaged with the mounting groove 512 of the mounting frame 50, so that the first fixing member 20 is connected to the mounting frame 50. It can be understood that the clamping joint 22 and the mounting groove 512 are helpful to increase the force-bearing area between the first fixing member 20 and the mounting frame 50, thereby helping to improve the wind resistance of the first fixing member 20 and the mounting frame 50 and reduce the risk of the first fixing member 20 and the mounting frame 50 being disengaged.

[0069] Furthermore, the first fastener 41 passes through the through hole 511 of the mounting frame 50 and is fixed to the first fixing member 20 through the first connecting hole 211. The end of the first fastener 41 is clamped in the through hole 511, and the first fastener 41 is used to limit the first fixing member 20 along the axial direction of the mounting frame 50, which helps to prevent the first fixing member 20 from slipping off the mounting frame 50.

[0070] Furthermore, the first extension section 23 extends from the other end of the first main section 21 to the groove 652 of the locking portion 65 relative to the clamping joint 22, and a first accommodating cavity 25 is formed between the clamping joint 22, the first main section 21 and the first extension section 23 to accommodate part of the frame body 51 of the installation frame 50 and the locking portion 65 of the tile 60, so that the locking portion 65 is located between the frame body 51 and the first extension section 23, and the first fixing member 20 is hooked with the tile 60.

[0071] In at least one embodiment, the first fastener 41 is a self-tapping screw. It can be understood that by prefabricating the first connecting hole 211 on the first fixing member 20, the resistance of the self-tapping screw to be screwed into the first fixing member 20 can be reduced, and it is helpful to avoid the self-tapping screw from being twisted, thereby improving the installation efficiency and installation quality.

[0072] In some embodiments, reference Figures 8 to 10 The first fixing member 20 is further provided with a first inclined surface 24 , which is obliquely arranged at the connection angle between the first main section 21 and the first extension section 23 , so that the first inclined surface 24 is inclined to bear against the locking portion 65 in the first accommodating cavity 25 .

[0073] It can be understood that by setting the first slope 24, the wall thickness at the corner of the first main section 21 and the first extension section 23 can be increased, and the first slope 24 is inclined, so as to improve the connection strength between the first main section 21 and the first extension section 23 and reduce the stress concentration at the corner, which is beneficial to improve the structural strength of the first fixing member 20 and further improve the wind-resistant ability of the photovoltaic roof system.

[0074] Further, see Figure 7 and Fig.11 When the first fixing member 20 is installed on the tile 60, the locking portion 65 of the tile 60 is able to abut against the first inclined surface 24, which is beneficial to increase the friction between the first fixing member 20 and the tile 60, and to prevent the first fixing member 20 from sliding relative to the tile 60, thereby improving the connection reliability between the first fixing member 20 and the tile 60.

[0075] In some embodiments, reference Figures 12 to 16 The second fixing member 30 includes a second main body section 31, a butt joint 32, a second extension section 33 and an adjusting member 421. The butt joint 32 protrudes from one end of the second main body section 31 toward the frame main body 51. The second connecting hole 311 is opened in the second main body section 31. The adjusting member 421 is installed in the installation groove 512 and is aligned with the through hole 511 and the second connecting hole 311, which is suitable for the fastener to pass through. The adjusting member 421 is able to adjust the installation distance between the mounting frame 50 and the second main body section 31 on both sides of the fastener. The second extension section 33 extends from the other end of the second main body section 31 toward the locking portion 65 of the tile 60. The second accommodating cavity 35 is formed between the mounting frame 50 and the second extension section 33. The locking portion 65 is embedded in the second accommodating cavity 35 and bent to cover the second extension section 33.

[0076] That is, the abutment head 32 of the second fixing member 30 is adapted to abut against the slot section 513 of the mounting frame 50, so that the abutment head 32 and the slot section 513 are in line contact, and the second fixing member 30 can be rotated relative to the mounting frame 50. It can be understood that by rotating the abutment head 32 relative to the slot section 513, the angle of the second main body section 31 relative to the mounting frame 50 can be adjusted, and then on the basis of keeping the abutment head 32 in contact with the slot section 513, the adjustment member 421 in the mounting groove 512 is aligned with the second connection hole 311 on the second fixing member 30, so that the second fastener 42 passes through the second connection hole 311 and is screwed with the adjustment member 421, which is conducive to reducing the difficulty of installation, improving the installation efficiency, and reducing the requirements for the manufacturing accuracy of the second fixing member 30, thereby reducing the manufacturing cost.

[0077] Further, see Fig.12 , the adjusting member 421 is installed in the installation groove 512, and the second fastener 42 passes through the second connection hole 311 of the second fixing member 30 and the opening of the installation groove 512 of the mounting frame 50, so as to be screwed with the adjusting member 421 and pass through the through hole 511, so as to fix the second fastener 42 to the second fixing member 30. It can be understood that the end of the second fastener 42 passes through the through hole 511, and the second fastener 42 can limit the second fixing member 30 along the axial direction of the mounting frame 50, which is conducive to preventing the first fixing member 20 from slipping off the mounting frame 50. In at least one embodiment, the second fastener 42 is a bolt and the adjusting member 421 is a nut.

[0078] Furthermore, the second extension section 33 extends from the other end of the second main section 31 to the groove 652 of the locking portion 65 relative to the abutment joint 32, and a second accommodating cavity 35 is formed between the abutment joint 32, the second main section 31 and the second extension section 33 to accommodate part of the frame body 51 of the mounting frame 50 and the locking portion 65, so that the locking portion 65 is located between the frame body 51 and the second extension section 33, and the second fixing member 30 is hooked with the tile 60.

[0079] In some embodiments, reference Figures 13 to 15 The second fixing member 30 is further provided with a second inclined surface 34 , which is obliquely arranged at the connecting angle between the second main section 31 and the second extension section 33 , so that the second inclined surface 34 is inclined to bear against the locking portion 65 in the second accommodating cavity 35 .

[0080] It can be understood that by setting the second slope 34, the wall thickness at the corner of the second main section 31 and the second extension section 33 can be increased, and the second slope 34 is inclined, so as to improve the connection strength of the second main section 31 and the second extension section 33 and reduce the stress concentration at the corner, which is beneficial to improve the structural strength of the second fixing member 30 and further improve the wind-resistant ability of the photovoltaic roof system.

[0081] Further, see Fig.12 and Fig.16 When the second fixing member 30 is installed on the tile 60, the locking portion 65 of the tile 60 is able to abut against the second inclined surface 34, which is beneficial to increase the friction between the second fixing member 30 and the tile 60, and to prevent the second fixing member 30 from sliding relative to the tile 60, thereby improving the connection reliability between the second fixing member 30 and the tile 60.

[0082] In at least one embodiment, when the first fixing member 20 and the second fixing member 30 are installed on the tile 60, the first inclined surface 24 of the first fixing member 20 and the second inclined surface 34 of the second fixing member 30 are inclined in opposite directions, so that the first inclined surface 24 and the second inclined surface 34 provide forces on the tile 60 in opposite directions, which is beneficial for making the force on the tile 60 more uniform.

[0083] It is worth mentioning that in at least one embodiment, both sides of the photovoltaic assembly 90 are connected to the tile 60 through the first fixing member 20. In at least one embodiment, both sides of the photovoltaic assembly 90 are connected to the tile 60 through the second fixing member 30. It is understandable that the use of the first fixing member 20 or the second fixing member 30 is conducive to reducing the types of parts of the photovoltaic roof system, thereby reducing the production cost of the photovoltaic roof system. In at least one embodiment, one side of the photovoltaic assembly 90 is connected to the tile 60 through the first fixing member 20, and the other side is connected to the tile 60 through the second fixing member 30, which is conducive to reducing the installation difficulty of the photovoltaic roof system through the first fixing member 20 and the second fixing member 30, thereby improving the installation efficiency.

[0084] In some embodiments, reference Fig.17 The tile 60 further includes a supporting portion 63, which protrudes from the main body 61 between the locking portions 65 toward the photovoltaic assembly 90 at intervals, and is suitable for supporting the middle part of the photovoltaic assembly 90. Figures 1 to 4The photovoltaic roof system further includes a fixed support 70, a wind-resistant support 80, an adhesive 101 and a gasket 102. The fixed support 70 is fixedly connected to the locking edge portion of the adjacent tile 60. The wind-resistant support 80 is embedded in the supporting portion 63 and is suitable for maintaining the height of the supporting portion 63. The adhesive 101 is arranged on the upper surface of the receiving portion 52, and the mounting frame 50 and the back of the photovoltaic module 90 are bonded by the adhesive 101. The gasket 102 is suitable for being installed between the supporting portion 63 and the photovoltaic module 90.

[0085] It is understandable that the support portion 63 of the tile 60 has a support surface 631 on the side facing the photovoltaic module 90, and a gasket 102 is sandwiched between the support surface 631 and the photovoltaic module 90, which is conducive to avoiding hard contact between the support surface 631 and the photovoltaic module 90, thereby reducing the risk of hidden cracks in the photovoltaic module 90. Further, the support portion 63 is suitable for being embedded with the wind-resistant support 80 fixed on the roof, thereby helping to improve the wind resistance of the tile 60, and the wind-resistant support 80 can be offset against the support surface 631 of the support portion 63, so as to support the middle area of ​​the photovoltaic module 90, which is conducive to reducing the suspended span of the photovoltaic module 90, thereby improving the bearing capacity of the photovoltaic module 90.

[0086] In some embodiments, reference Fig. 20 The fixed support 70 includes a support body 71, a support section 72, a supporting section 73 and a locking section 74. The support body 71 is placed on the roof and fixed to the purlin through the third fastener 43. Further, the two ends of the support body 71 respectively have support sections 72, and the support section 72 extends from the support body 71 in the direction away from the roof, and the supporting section 73 extends horizontally from one end of the support section 72 away from the support body 71 to the side away from the support body 71, so as to fit with the horizontal part of the covering section 653 of the tile 60, thereby supporting the locking portion 65 of the tile 60. Further, the locking section 74 extends from one side of the support body 71 in the direction away from the roof, and the locking section 74 is stacked and bent with the locking section 654 of the tile 60 to form a tile rib 66, so that two adjacent tiles 60 are connected and fixed to the fixed support 70 together, thereby fixing the tile 60 to the roof.

[0087] In at least one embodiment, before leaving the factory, the mounting frame 50 and the photovoltaic module 90 are bonded and fixed. Further, at the construction site, the tiles 60 are installed on the purlins through the fixing brackets 70 and the wind-resistant brackets 80. After obtaining a qualified metal roof, the installation steps of the photovoltaic roof system further include:

[0088] S1, slide the clamping joint 22 of the first fixing member 20 into the mounting groove 512 of the mounting frame 50 on one side of the photovoltaic assembly 90, and fix the first fixing member 20 to the mounting frame 50 through the first fastener 41;

[0089] S2, slide the adjustment member 421 into the installation groove 512 of the installation frame 50 on the other side of the photovoltaic assembly 90, and connect the second fixing member 30 to the installation frame 50 through the cooperation of the second fastener 42 and the adjustment member 421;

[0090] S3, hooking the first fixing member 20 with the locking portion 65 on one side of the tile 60;

[0091] S4, hook the second fixing member 30 with the locking portion 65 on the other side of the tile 60, and tighten the second fastener 42 to fix the photovoltaic component 90 to the tile 60.
