[0083] Referring to Figures 1 to 6 An embodiment of the present application provides a frame 200, which comprises a substrate 210, a mounting plate 220 and a first support plate 230. The mounting plate 220 is arranged spaced apart from the substrate 210, and the side of the mounting plate 220 away from the substrate 210 is used for fixed connection with a photovoltaic module 20. The first support plate 230 is arranged between the substrate 210 and the mounting plate 220, and the two ends of the first support plate 230 are connected to the substrate 210 and the mounting plate 220 respectively. The substrate 210, the mounting plate 220 and the first support plate 230 jointly enclose a mounting groove 240. The opening of the mounting groove 240 is along a first direction and away from the photovoltaic module 20, and the first direction is the arrangement direction of two adjacent photovoltaic modules 20.

[0084] This technical solution provides a frame 200 for connecting to a photovoltaic module 20. A substrate 210 supports a mounting plate 220 and a first support plate 230, and is used to support the photovoltaic module 20 on a mounting bracket 60 during installation. The mounting plate 220 is fixedly connected to the photovoltaic module 20, thereby achieving the connection between the entire frame 200 and the photovoltaic module 20. By connecting the mounting plate 220 to the photovoltaic module 20, the entire frame 200 is without an A-side, thus exposing the entire light-facing surface of the photovoltaic module 20 without shading from the frame 200. This improves the power generation efficiency of the photovoltaic module 20 and reduces dust accumulation on its light-facing surface. Furthermore, by fixing the mounting plate 220 of the frame 200 to the photovoltaic module 20, the area of ​​the connection surface between the frame 200 and the photovoltaic module 20 is increased, thereby improving the connection strength and reliability between the photovoltaic module 20 and the frame 200. The mounting plate 220 and the substrate 210 are spaced apart to form a mounting groove 240 between them. Specifically, a first support plate 230 is provided between the substrate 210 and the mounting plate 220 to form a mounting groove 240 for mounting the pressure block 30. The opening of the mounting groove 240 in the frame 200 is set along the first direction X and away from the photovoltaic module, so that the mounting groove 240 of the frame 200 faces outward, which facilitates connection with the pressure block 30. In addition, by forming the mounting groove 240 on the frame 200 with the above structure, the pressure block 30 is positioned on the back surface of the photovoltaic module 20 through the installation of the pressure block 30 with the mounting groove 240. This prevents the pressure block 30 from applying load to the light-facing surface of the photovoltaic module 20, i.e., the glass, thereby reducing the risk of the glass of the photovoltaic module 20 cracking due to the load of the pressure block 30 during installation.

[0085] It is understood that the photovoltaic module 20 has a backlighting surface and a light-facing surface arranged opposite to each other. The light-facing surface is the side that receives sunlight, and the backlighting surface is the side that faces away from the light-facing surface. The frame 200 is fixedly connected to the edge of the backlighting surface of the photovoltaic module 20. The first direction is the arrangement direction of the two photovoltaic modules in the photovoltaic system, that is, as shown in the figure. Figure 1 The X direction is shown.

[0086] In this embodiment, the substrate 210, mounting plate 220, and first support plate 230 are all thin plate structures, and the substrate 210, mounting plate 220, and first support plate 230 are integrally formed to form the frame 200. Specifically, the frame 200 is made of aluminum alloy and is integrally formed by extrusion.

[0087] like Figure 1As shown in the drawings, in one embodiment, the substrate 210 is inclined towards the side of the mounting groove 240, away from the end of the first support plate 230, in the direction away from the mounting plate 220. In other words, the end of the substrate 210 away from the first support plate is configured as an inclined surface inclined downwardly towards the side of the mounting groove 240. In this way, when the frame 200 is connected with the pressing block 30, the pressing block 30 can be guided by the inclined surface on the substrate 210, thereby facilitating the connection of the pressing block 30 with the frame 200.

[0088] In the present embodiment, the end of the substrate 210 towards the pressing block 30 is configured as a circular arc, so as to prevent the bottom of the frame 200 from having sharp edges that can scratch the operator during installation.

[0089] As shown in the drawings, in one embodiment, the substrate 210 is inclined towards the side of the mounting groove 240, away from the end of the first support plate 230, in the direction away from the mounting plate 220. In other words, the end of the substrate 210 away from the first support plate is configured as an inclined surface inclined downwardly towards the side of the mounting groove 240. In this way, when the frame 200 is connected with the pressing block 30, the pressing block 30 can be guided by the inclined surface on the substrate 210, thereby facilitating the connection of the pressing block 30 with the frame 200. Figure 2

[0090] Specifically, the anti-extraction boss protrudes towards the direction close to the mounting plate 220. In this way, when the end of the pressing block 30 is installed into the mounting groove 240, the pressing block 30 can be guided by the inclined surface on the anti-extraction boss, thereby facilitating the installation of the pressing block 30 into the mounting groove 240. More specifically, the cross-sectional shape of the anti-extraction boss is substantially an obtuse triangle.

[0091] In another embodiment, in order to improve the anti-extraction performance of the frame 200 and the pressing block 30, a plurality of anti-extraction bosses can be arranged on the substrate 210 at intervals, and correspondingly, a plurality of anti-extraction grooves can be arranged on the pressing block 30 to match the anti-extraction bosses. The anti-extraction bosses and the anti-extraction grooves are matched in concave-convex manner, so as to limit the pressing block 30, thereby preventing the pressing block 30 from being extracted.

[0092] It can be understood that, in the present embodiment, the height of the anti-extraction boss should not be too high, so as to facilitate the pressing block 30 to pass over the anti-extraction boss and enter into the mounting groove 240. The anti-extraction boss can extend along the length direction of the substrate 210, or can extend intermittently in the length direction of the substrate 210.

[0093] As shown in the drawings, in one embodiment, the substrate 210 is inclined towards the side of the mounting groove 240, away from the end of the first support plate 230, in the direction away from the mounting plate 220. In other words, the end of the substrate 210 away from the first support plate is configured as an inclined surface inclined downwardly towards the side of the mounting groove 240. In this way, when the frame 200 is connected with the pressing block 30, the pressing block 30 can be guided by the inclined surface on the substrate 210, thereby facilitating the connection of the pressing block 30 with the frame 200. Figures 1 to 6 ​As shown, in one of the embodiments, the mounting plate 220 is provided with a limiting protrusion 221 at the end of the side of the mounting groove 240. By providing the limiting protrusion 221 at the end of the side of the mounting plate 220, when the pressing block 30 is connected with the frame 200, the limiting protrusion 321 on the pressing block 30 is hooked with the limiting protrusion 221 on the mounting plate 220 of the frame 200, so that the end of the pressing block 30 can be reliably mounted in the mounting groove 240 of the frame 200.

[0094] Specifically, the limiting protrusion 221 comprises a guiding surface 2211 and a resisting surface 2212, the guiding surface 2211 is arranged at an angle with the mounting plate 220 and faces away from the first supporting plate 230, and the resisting surface 2212 faces the first supporting plate 230. The angle between the resisting surface 2212 and the mounting plate 220 is one of an acute angle, a right angle or an obtuse angle.

[0095] The guiding surface 2211 is used for guiding the pressing block 30 when the end of the pressing block 30 is mounted in the mounting groove 240. The line between the two ends of the guiding surface 2211 is arranged to be inclined to the mounting plate 220, and the guiding surface 2211 is arranged at the end away from the corner code cavity 250. In this way, when the pressing block 30 is mounted, the pressing block 30 first contacts the guiding surface 2211, and the end of the pressing block 30 entering the mounting groove 240 is guided by the inclined surface of the guiding surface 2211. Specifically, the guiding surface 2211 can be a flat surface or a curved surface with a certain curvature. The distance between the guiding surface 2211 and the mounting plate 220 gradually increases from the end away from the corner code cavity 250 to the end close to the corner code cavity 250. The resisting surface 2212 is used for resisting the limiting protrusion 321 on the pressing block 30, thereby preventing the pressing block 30 from being separated from the mounting groove 240.

[0096] When the angle between the resisting surface 2212 and the mounting plate 220 is an acute angle, the limiting protrusion 221 structure formed by the resisting surface 2212 and the guiding surface 2211 is inclined to the direction close to the first supporting plate 230 to form a barb structure. In this way, when the end of the pressing block 30 is mounted in the mounting groove 240, the limiting protrusion 321 on the pressing block 30 is hooked with the limiting protrusion 221 on the mounting surface of the frame 200, thereby improving the performance of the mutual limiting of the limiting protrusion 321 and the limiting protrusion 221, preventing the pressing block 30 from being separated from the mounting groove 240, and further ensuring the reliability of the connection between the pressing block 30 and the frame 200.

[0097] When the included angle between the resisting surface 2212 and the mounting plate 220 is a right angle, the limiting protrusion 221 formed by the resisting surface 2212 and the guiding surface 2211 is a right triangle structure. In this way, when one end of the pressing block 30 is mounted into the mounting groove 240, the side surface of the limiting protrusion 321 on the pressing block 30 abuts against the resisting surface 2212 on the limiting protrusion 221, thereby ensuring the mutual limiting performance of the limiting protrusion 321 and the limiting protrusion 221, preventing the pressing block 30 from being separated from the mounting groove 240, and further ensuring the reliability of the connection between the pressing block 30 and the frame 200.

[0098] In another embodiment, the resisting surface 2212 can also be arranged in the form that the included angle between the resisting surface 2212 and the mounting plate 220 is an obtuse angle, so that the limiting protrusion 221 formed by the resisting surface 2212 and the guiding surface 2211 and the mounting plate 220 is an obtuse triangle with a vertex pointing to the base plate 210. In this way, while ensuring the reliability of the limiting protrusion 221 on the frame 200 limiting the limiting protrusion 321 on the pressing block 30, the pressing block 30 is facilitated to be dismounted from the mounting groove 240.

[0099] It can be understood that the limiting protrusion 221 continuously extends along the length direction of the mounting plate 220. In this way, the structural strength of the limiting protrusion 221 is ensured; in addition, the mounting position of the pressing block 30 is not limited, that is, the pressing block 30 can be mounted at any position along the length direction of the frame 200, thereby improving the convenience of the installation of the pressing block 30.

[0100] As shown in FIG. 2A, Figure 4 In one of the embodiments, the end of the mounting plate 220 and the base plate 210 away from the first support plate 230 is arranged in a circular arc structure. By arranging the end of the mounting plate 220 and the base plate 210 away from the first support plate 230 in a circular arc structure, the end of the mounting plate 220 and the base plate 210 is relatively smooth, thereby preventing the risk of scratching the operator during the installation process.

[0101] As shown in FIG. 2A, Figure 6 In one of the embodiments, the end of the mounting plate 220 away from the first support plate 230 is provided with a folded edge 222, and the folded edge 222 is used to abut against the end of the photovoltaic module 20, and the end of the folded edge 222 is lower than the light-receiving surface of the photovoltaic module 20. By arranging the end of the mounting plate 220 away from the first support plate 230 with the folded edge 222 and abutting the folded edge 222 against the end of the photovoltaic module 20, the strength of the end of the photovoltaic module 20 is strengthened by the folded edge 222 of the mounting plate 220. In addition, the end of the folded edge 222 is arranged to be lower than the light-receiving surface of the photovoltaic module 20, so as to prevent the folded edge 222 of the mounting plate 220 from protruding from the light-receiving surface of the photovoltaic module 20, thereby preventing dust from being easily accumulated between the folded edge 222 and the photovoltaic module 20. ​​​​

[0102] As shown in Figure 6 one of the embodiments, the substrate 210 extends away from the end of the mounting groove 240 in a direction away from the mounting groove 240. By extending the end of the substrate 210 away from the mounting groove 240 in a direction away from the mounting groove 240, the area of the substrate 210 is increased, thereby improving the structural strength of the entire frame 200, and thus improving the overall strength and rigidity of the photovoltaic module 20, thereby meeting the overall mechanical load performance of the photovoltaic module 20.

[0103] As shown in Figure 5 one of the embodiments, at least part of the area of the surface of the mounting plate 220 connected to the photovoltaic module 20 is provided as a wavy surface 223. By providing at least part of the area of the surface of the mounting plate 220 connected to the photovoltaic module 20 as a wavy surface 223, the adhesion of the contact surface between the adhesive and the mounting plate 220 can be improved. Thus, the connection strength and reliability between the photovoltaic module 20 and the mounting plate 220 can be improved.

[0104] In one of the embodiments, the frame 200 further comprises a second support plate 260, which is arranged between the substrate 210 and the mounting plate 220, and is located on the side of the first support plate 230 away from the mounting groove 240 and spaced apart from the first support plate 230; the first support plate 230, the mounting plate 220, the second support plate 260, and the substrate 210 together enclose an angle code cavity 250 for mounting the angle code 100. By arranging as above, the angle code cavity 250 is formed on the frame 200, so that the two adjacent frames 200 can be connected through the angle code cavity 250 and the angle code 100, thereby realizing the connection of the two adjacent frames 200. While improving the aesthetics of the frame assembly, the connection strength of the two frames 200 can be improved.

[0105] As shown in Figures 7 to 11 another embodiment of the present application further provides a frame assembly 10, which comprises the frame 200 and the angle code 100 as above, and a plurality of frames are sequentially connected end to end; the two connecting arms of the angle code 100 are respectively inserted into the angle code cavities 250 of the two adjacent frames 200, so as to realize the mutual connection of the two adjacent frames 200.

[0106] By inserting the two connecting arms of the angle code 100 into the angle code cavities 250 of the two adjacent frames 200, the connection of the frame 200 and the angle code 100 is realized. The four frames 200 are respectively connected to the four angle codes 100, thereby forming a frame assembly 10 of a rectangular structure. The frame assembly 10 is used to connect the four peripheral edges of the back surface of the photovoltaic module 20.

[0107] Specifically, the corner code 100 comprises a first corner code 110 and a second corner code 120, the first corner code 110 comprises a first side wall 111 and a second side wall 112, the first side wall 111 and the second side wall 112 enclose a connecting groove 113; the second corner code 120 comprises a first connecting arm 121 and a second connecting arm 122 which are connected to each other and arranged at an angle, and a corner formed by the connection of the first connecting arm 121 and the second connecting arm 122 is installed in the connecting groove 113; wherein the first side wall 111 is connected with the first connecting arm 121, and the second side wall 112 is connected with the second connecting arm 122, and the first connecting arm 121 and the second connecting arm 122 are used to connect with two adjacent frame borders 200.

[0108] By constructing the connecting groove 113 on the first corner code 110, and by installing the corner of the second corner code 120 in the connecting groove 113, the preliminary connection of the first corner code 110 and the second corner code 120 is achieved. By connecting the first connecting arm 121 with the first side wall 111 of the connecting groove 113, and by connecting the second connecting arm 122 with the second side wall 112 of the connecting groove 113, the fixation of the first corner code 110 and the second corner code 120 is achieved, so that the first corner code 110 and the second corner code 120 are integrated. By connecting the first connecting arm 121 and the second connecting arm 122 with two adjacent frame borders 200, the two adjacent frame borders 200 are tightly assembled and connected together through the corner code 100, so that the packaging, fastening and bearing functions of the frame border 200 are achieved. Through the above structure, the corner code 100 is provided as two separate structures, so that the overall parts of the corner code 100 are less, and the structure and assembly process of the corner code 100 are simplified, thereby improving the assembly efficiency.

[0109] The connecting groove 113 on the first corner code 110 is a V-shaped groove, and the first side wall 111 and the second side wall 112 of the connecting groove 113 are arranged at a V-shaped angle, so as to form a V-shaped connecting groove 113. The first connecting arm 121 and the second connecting arm 122 in the second corner code 120 are also arranged at an angle, and the included angle between the first connecting arm 121 and the second connecting arm 122 is consistent with the included angle formed by the first side wall 111 and the second side wall 112 of the first corner code 110. In this way, the corner of the second corner code 120 can correspond to the shape of the connecting groove 113, so that the first connecting arm 121 can be connected with the first side wall 111, and the second connecting arm 122 can be connected with the second side wall 112, thereby achieving the mutual connection and fixation of the first corner code 110 and the second corner code 120.

[0110] It can be understood that when connecting the frame 200 with the corner code 100, the end of the frame 200 needs to be cut into a 45-degree bevel, and after the ends of two adjacent frames 200 are butted, the two 45-degree bevels are spliced into a right angle structure. In this way, when the first connecting arm 121 and the second connecting arm 122 of the corner code 100 are respectively inserted into the two adjacent frames 200, the corner code 100 is just located at the right angle of the two frames 200, which can block the gap at the splicing position of the two frames 200 while achieving the mutual connection of the two frames 200, thereby improving the appearance of the appearance.

[0111] As shown in Figure 8 and Figure 9 In one embodiment, a first buckle 1111 is formed on the first side wall 111, and a clamping protrusion 1121 is formed on the second side wall 112; a second buckle 1211 is arranged on the first connecting arm 121, and the second buckle 1211 and the first buckle 1111 are clamped with each other; a clamping groove 1221 is arranged on the second connecting arm 122, and the clamping protrusion 1121 is clamped in the clamping groove 1221.

[0112] By forming the first buckle 1111 on the first side wall 111 and arranging the second buckle 1211 on the first connecting arm 121, the mutual connection and fixation of the first side wall 111 and the first connecting arm 121 are achieved through the mutual clamping of the first buckle 1111 and the second buckle 1211. By forming the clamping protrusion 1121 on the second side wall 112 and arranging the clamping groove 1221 on the second connecting arm 122, the mutual connection and fixation of the second side wall 112 and the second connecting arm 122 are achieved through the mutual clamping of the clamping protrusion 1121 and the clamping groove 1221. The above structure not only forms reliable cooperation, so that the corner code 100 is not easy to fall off, but also is easy to install and reliable in connection, thereby improving the connection tightness and strength between the two adjacent frames 200, and improving the appearance of the connection between the adjacent frames 200.

[0113] As shown in Figure 9 and Figure 10 In one embodiment, the first corner code 110 further includes a first limiting plate 114 and a second limiting plate 115, and the first limiting plate 114 and the second limiting plate 115 are respectively arranged at opposite ends of the connecting groove 113; the first limiting plate 114 is connected with one end of the first side wall 111 and the second side wall 112; the second limiting plate 115 is connected with the other end of the first side wall 111 and the second side wall 112; wherein the first limiting plate 114 and the second limiting plate 115 are used for limiting the opposite sides of the corner of the second corner code 120.

[0114] The first limiting plate 114 and the second limiting plate 115 are arranged at opposite ends of the connecting groove 113, and the opposite sides of the corner of the second corner code 120 are limited by the first limiting plate 114 and the second limiting plate 115, so as to further improve the reliability of the connection between the first corner code 110 and the second corner code 120. In addition, through the above arrangement, after the frame 200 is assembled, only the first side plate, the second side plate, the first limiting plate 114 and the second limiting plate 115 of the first corner code 110 are exposed outside, so that the outer package is an integral whole, the color is uniform, and the three-section structure is more beautiful. The first corner code 110 is an integral structure, and the shape can be customized, for example, the connection between the first side plate and the second side plate, the connection between the first limiting plate 114 and the first side plate and the second side plate, and the connection between the second limiting plate 115 and the first side plate and the second side plate can be arc or chamfered, so as to avoid scratching the worker during installation. In addition, a company logo or the like can be arranged on the exposed side of the first corner code 110.

[0115] As shown in Figure 10 one of the embodiments, the outer side edges of the first limiting plate 114 and the second limiting plate 115 extend beyond the outer side surfaces of the first side wall 111 and the second side wall 112; the outer side edge of the first limiting plate 114 is flush with the end of the mounting plate 220 of the frame 200 away from the corner code cavity 250; and the outer side edge of the second limiting plate 115 is flush with the end of the base plate 210 of the frame 200 away from the corner code cavity 250.

[0116] The outer side edges of the first limiting plate 114 and the second limiting plate 115 extend beyond the outer side surfaces of the first side wall 111 and the second side wall 112. By arranging the outer side edges of the first limiting plate 114 and the second limiting plate 115 to extend beyond the outer side surfaces of the first side wall 111 and the second side wall 112, the area of the first limiting plate 114 and the second limiting plate 115 is increased, so as to improve the pressure bearing capacity of the corner code 100. In addition, the outer side edge of the first limiting plate 114 is arranged to be flush with the end of the mounting plate 220 of the frame 200 away from the corner code cavity 250, and the outer side edge of the second limiting plate 115 is arranged to be flush with the end of the base plate 210 of the frame 200 away from the corner code cavity 250. In this way, after the corner code 100 is connected with the frame 200, the recess formed by the first limiting plate 114, the second limiting plate 115, the first side plate and the second side plate on the corner code 100 is consistent with the mounting groove 240 of the frame 200, so as to improve the appearance of the frame assembly 10.

[0117] As shown in Figure 8 and Figure 1As shown, in one embodiment, the inner side surface of the first connecting arm 121 and the second connecting arm 122 is provided with the first limiting structure 1212 which is sequentially connected by concave-convex; the frame 200 is provided with the corner code cavity 250, and the cavity wall of the corner code cavity 250 is provided with the second limiting structure 251 which is sequentially connected by concave-convex; wherein the first limiting structure 1212 and the second limiting structure 251 are matched with each other by concave-convex, and are limited to each other.

[0118] By providing the first limiting structure 1212 which is sequentially connected by concave-convex on the inner side surface of the first connecting arm 121 and the second connecting arm 122, and providing the second limiting structure 251 which is sequentially connected by concave-convex on the cavity wall of the corner code cavity 250 of the frame 200, and matching the first limiting structure 1212 and the second limiting structure 251 with each other by concave-convex to limit each other, the reliability of the connection between the first connecting arm 121, the second connecting arm 122 and the frame 200 is improved, so as to prevent the corner code 100 from falling off. Figures 11 to 13 As shown, an embodiment of the present application further provides a photovoltaic system 1000, which comprises the frame assembly 10 and the photovoltaic assembly 20 as above, the photovoltaic assembly comprises the light-receiving surface and the back surface which are oppositely arranged; the frame assembly 10 is arranged at the four peripheral edges of the back surface; the mounting plate 220 of the frame 200 is fixedly connected with the back surface of the photovoltaic assembly 20.

[0119] By arranging the frame assembly 10 as above at the four peripheral edges of the back surface of the photovoltaic assembly 20, the photovoltaic assembly 20 is strengthened by the frame assembly 10. Meanwhile, the frame assembly 10 is used to establish the connection with the mounting support 60, so as to facilitate the connection of the photovoltaic assembly 20 on the corresponding building. By using the frame assembly 10 as above in the photovoltaic assembly 20, the entire light-receiving surface of the entire photovoltaic assembly 20 is exposed, which can prevent the dust and water from accumulating on the light-receiving surface of the photovoltaic assembly 20, thereby improving the power generation efficiency of the photovoltaic assembly 20; on the other hand, the area of the surface of the photovoltaic assembly 20 connected with the frame 200 is larger, thereby improving the connection strength of the photovoltaic assembly 20 and the frame 200.

[0120] In one of the embodiments, the photovoltaic system 1000 comprises a plurality of photovoltaic modules 20 arranged at intervals, each of the photovoltaic modules 20 is correspondingly connected with a frame assembly 10, and the photovoltaic module 20 further comprises a pressing block 30, the pressing block 30 comprises two oppositely arranged side walls 310 and a bottom wall 330 arranged at an angle with the side walls 310, the two side walls 310 are arranged along a first direction, and the two side walls 310 and the bottom wall 330 enclose a groove; the two side walls 310 are respectively configured with a top part 320 which is movable up and down, the top part 320 is located at a slot of the groove and faces the groove; wherein, one end of each of the two top parts 320 which faces the other is provided with a limiting protrusion 321, the limiting protrusion 321 is arranged on a side of the top part 320 which is away from the bottom wall 330, the limiting protrusion 321 protrudes upward, and the limiting protrusion 321 is used for limiting the connection with the limiting clamping protrusion on the frame. Specifically, the limiting protrusion 321 is arranged at the end of each of the two top parts 320 of the pressing block 30 which is close to the other, so that when the pressing block 30 is clamped with the frame 200 on the photovoltaic module 20, the left and right ends of the pressing block 30 are respectively installed into the installation slot 240 of the frame 200. On the one hand, the contact area between the pressing block 30 and the slot wall of the installation slot 240 of the frame 200 is larger, so that the connection strength between the pressing block 30 and the frame 200 is more reliable; on the other hand, the distance between adjacent photovoltaic modules 20 can be reduced, so that the installation area of the photovoltaic module 20 per unit area is increased.

[0121] In the embodiment, the pressing block 30 as above is combined with the installation slot 240 of the frame 200, so that the slot depth of the installation slot 240 of the frame 200 is set to be deeper to accommodate the deformation space required by the elastic deformation of the top part 320 of the pressing block 30. In addition, for photovoltaic modules 20 of different sizes, only the position of the first supporting plate 230 in the installation slot 240 needs to be changed, so that the mold opening cost can be reduced.

[0122] As shown in Figures 11 to 13 In one of the embodiments, the photovoltaic system 1000 further comprises a tape layer 50 and a glue layer 40, the opposite two adhesive surfaces of the tape layer 50 are respectively adhered to the back light surface of the photovoltaic module 20 and the installation plate 220 of the frame 200; the glue layer 40 is arranged on the installation plate 220 and adhered to the back light surface of the photovoltaic module 20; the tape layer 50 and the glue layer 40 are arranged along the first direction.

[0123] Specifically, the adhesive tape layer 50 is arranged above the corner code cavity 250, and the adhesive tape layer 50 is a double-sided adhesive tape, which is used to control the thickness of the adhesive layer, so as to ensure the reliability of the connection between the frame 200 and the photovoltaic module 20. In addition, the adhesive tape layer can also save the adhesive. In the embodiment, in order to improve the speed of the connection between the frame 200 and the photovoltaic module 20, a demarcation groove 224 is arranged on the mounting plate 220 of the frame 200 to indicate the position of the double-sided adhesive tape, so that the position of the double-sided adhesive tape can be aligned during installation. It can be understood that the positions of the adhesive tape layer 50 and the adhesive layer 40 in the first direction are not limited, and the adhesive tape layer 50 can be arranged on the left side and the adhesive layer 40 can be arranged on the right side. Alternatively, the adhesive layer 40 can be arranged on the left side and the adhesive tape layer 50 can be arranged on the right side.

By arranging the adhesive tape layer 50 and the adhesive layer 40 in a spaced manner, the water leakage groove is formed between the adhesive tape layer 50 and the adhesive layer 40. Thus, when the photovoltaic module 20 is applied to a photovoltaic roof, the photovoltaic module 20 is arranged in an inclined manner, and water can be drained through the water leakage groove, thereby improving the drainage performance of the photovoltaic system 1000. As shown in FIG. 1, the embodiment of the present application also provides a mounting method of a photovoltaic system, and the mounting method comprises the following steps: Figures 14 to 18

For example, the right end of the pressing block 30 is pushed into the mounting slot 240 along the mounting slot 240 on the frame 200 corresponding to the photovoltaic assembly 20 on the right side. In this process, the top part 320 is elastically deformed under the action of the limiting protrusion 221 on the frame 200, when the limiting protrusion 321 on the top part 320 passes the upper limiting protrusion 221 on the frame 200, the right end of the pressing block 30 is mounted in place with the frame 200 corresponding to the photovoltaic assembly 20 on the right side.
