Description

Technical Field

[0001] This application relates to the field of photovoltaic component technology, and specifically to a photovoltaic component. Background Technology

[0002] Photovoltaic (PV) components, as an important part of rooftop power stations, are used to convert received solar energy into electricity to meet daily production and usage needs. A PV component consists of corrugated steel sheets connected to the roof, clamps installed on the sheets, and PV modules held and fixed by the clamps. Existing PV components still suffer from problems such as inconvenient installation of the PV modules and low installation efficiency. Summary of the Invention

[0003] In view of this, this application provides a photovoltaic component to help solve the problem of low installation efficiency of photovoltaic modules in the prior art.

[0004] This application provides a photovoltaic component, including: a photovoltaic module; and a support, including a first support member and a second support member. The first support member includes a first part, a second part, and a third part. Along the height direction of the support, the first part and the third part are respectively connected to the two ends of the second part. The first part, the second part, and the third part form a receiving cavity. The first part is connected to the backlight surface of the photovoltaic module. The second support member includes a main body. The second support member can slide with the first support member along the width direction of the support, so that the main body is detachably connected to the receiving cavity.

[0005] In one possible implementation, the first bracket further includes a first guide portion, which is fixedly connected to the end of the first portion away from the second portion along the width direction of the bracket, and the height difference between the first guide portion and the backlight surface gradually decreases along the width direction of the bracket; and / or, the first bracket further includes a second guide portion, which is fixedly connected to the end of the third portion away from the second portion along the width direction of the bracket, and the height difference between the second guide portion and the backlight surface gradually increases along the width direction of the bracket.

[0006] In one possible implementation, a support plane is provided at the end of the first guide portion away from the first portion along the width direction of the bracket; the support plane abuts against the backlight surface along the height direction of the bracket.

[0007] In one possible implementation, the main body has a first surface and a second surface disposed opposite to each other along the height direction of the bracket; the first surface is provided with a first protrusion that protrudes outward along the height direction of the bracket; and / or, the second surface is provided with a second protrusion that protrudes outward along the height direction of the bracket.

[0008] In one possible implementation, a first guide slope is provided on the first surface near the end of the second part along the width direction of the bracket; and / or, a second guide slope is provided on the second surface near the end of the second part along the width direction of the bracket.

[0009] In one possible implementation, the height of the first support member is H1, where 15mm ≤ H1 ≤ 20mm.

[0010] In one possible implementation, along the height direction of the bracket, the first part is provided with a receiving groove on the side facing the backlight surface, the receiving groove being used to receive adhesive; the first part is bonded and fixed to the backlight surface by the adhesive.

[0011] In one possible implementation, along the length of the bracket, the two ends of the first bracket member and the two ends of the second bracket member are respectively fixedly connected by locking members.

[0012] In one possible implementation, the photovoltaic component further includes a clamp and a corrugated steel sheet, the clamp being connected to the corrugated steel sheet, and the second support member being connected to the clamp to connect the photovoltaic module to the corrugated steel sheet.

[0013] In one possible implementation, the second bracket further includes a mounting portion, which is fixedly connected to the side of the main body away from the receiving cavity along the width direction of the bracket; a limiting groove is provided at the end of the mounting portion away from the main body along the height direction of the bracket, the limiting groove being used to accommodate a fastener; one end of the fastener is mounted in the limiting groove along the height direction of the bracket, and the other end is fixedly connected to the clamp.

[0014] In this application, the first and second support components are separate structures. The first support component can be pre-fixed to the back of the photovoltaic module in the factory to ensure the connection quality between the first support component and the photovoltaic module. The second support component can be fixedly connected to the ground or building roof at the installation site. Then, the photovoltaic module is installed on the ground or building roof through the sliding connection of the first and second support components, which helps to improve the installation efficiency and quality of photovoltaic modules during on-site installation. Moreover, the first support component has an opening along the width direction of the support, and the sliding connection between the first and second support components along the width direction of the support is shorter and easier to operate than the sliding connection along the length direction of the support, which also helps to improve the installation efficiency of photovoltaic modules. When photovoltaic (PV) modules are installed on a sloping roof, the opening of the first bracket should face the eaves. During installation, the second bracket can be fixed to the roof first, and then the connected PV module can be placed flat on top of the second bracket, aligning the receiving cavity with the main body. Next, a worker can stand below the PV module and pull it downwards along the eaves, causing the first bracket to wrap around the main body, thus connecting the first and second brackets and fixing the PV module to the roof. Using this split-structure bracket to install PV modules eliminates the need for workers to stand on the surface of the modules, avoiding trampling. This bracket is suitable not only for installing ordinary PV modules but also for lightweight, non-tramplable modules, offering greater versatility. Furthermore, using this split-structure bracket allows for two rows of PV modules to be continuously installed along the roof's height, reducing the number of maintenance access routes and increasing the installed capacity per unit area, which is beneficial for improving the power generation of the PV modules.

[0079] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0080] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0081] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0082] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0083] This application provides a photovoltaic component, such as... Figure 1 As shown, the photovoltaic component includes a photovoltaic module 100 and a support 200. The support 200 is used to connect to the back surface of the photovoltaic module 100 to install the photovoltaic module 100 onto the ground or building roof. Figure 2 As shown, the photovoltaic module 100 includes a laminate 110 and a frame 120. A support 200 is bonded to the back surface of the laminate 110. Frames 120 are provided around all four sides of the laminate 110 (i.e., the four edges of the laminate 110), and adjacent frames 120 are fixedly connected by corner brackets. Specifically, as shown... Figure 3 As shown, the frame 120 includes a first frame portion 1201, a second frame portion 1202, and a third frame portion 1203. The first frame portion 1201 and the third frame portion 1203 are disposed opposite each other along the height direction Z of the frame 120. The second frame portion 1202 extends along the height direction Z of the frame 120. The first frame portion 1201 and the third frame portion 1203 extend along the width direction X of the frame 120 and are respectively connected to the two ends of the second frame portion 1202 along the height direction Z of the frame 120. The first frame portion 1201, the second frame portion 1202, and the third frame portion 1203 form a connecting cavity 1205. The edge of the laminate 110 extends into the connecting cavity 1205 and is bonded and fixed to the connecting cavity 1205 to achieve a fixed connection between the laminate 110 and the frame 120. The frame 120 also has a corner bracket cavity 1206. Along the width direction X of the frame 120, the corner bracket cavity 1206 is located on the side of the connecting cavity 1205 away from the laminate 110. The corner bracket cavity 1206 is located on the side of the frame 120, which can prevent interference between the frame 120 and the locking structure of the color steel tile 400 along the height direction Z when the photovoltaic module 100 is installed on the color steel tile 400, thus facilitating the installation of the photovoltaic module 100. Specifically, as... Figure 3 As shown, the first frame portion 1201 and the third frame portion 1203 can extend along the width direction X of the frame 120 in a direction away from the laminate 110. The extended portions of the first frame portion 1201 and the extended portions of the third frame portion 1203 are fixedly connected by a fourth frame portion 1204 extending along the height direction Z of the frame 120, that is, a corner bracket cavity 1206 can be formed in front of the first frame portion 1201, the second frame portion 1202, the third frame portion 1203 and the fourth frame portion 1204. The corner bracket is usually a right-angle structure, and the same corner bracket is fixedly connected to the corner bracket cavity 1206 of two adjacent frame portions 120 to realize the connection between the two adjacent frame portions 120.

[0084] like Figure 11As shown, the laminate 110 includes a battery layer 111, a front panel 112, a back panel 113, and an encapsulant layer 114. The battery layer 111 comprises multiple series-connected or parallel battery strings, each battery string consisting of multiple battery cells 1111 (including but not limited to monocrystalline silicon cells and polycrystalline silicon cells) connected in series, with adjacent battery cells 1111 connected by solder ribbons 1112. The front panel 112 is located on the light-facing side of the battery layer 111, protecting the surface of the battery layer 111 and reducing the risk of damage to the battery cells 1111. The back panel 113 is located on the shaded side of the battery layer 111, providing moisture barrier and insulation protection. The encapsulant layer 114 includes a first encapsulant layer 1141 and a second encapsulant layer 1142. 42. Along the thickness direction Z of the laminate 110, the first adhesive film layer 1141 is located between the front panel 112 and the battery layer 111, and is used to fix the front panel 112 and the battery layer 111. The second adhesive film layer 1142 is located between the battery layer 111 and the back panel 113, and is used to fix the battery layer 111 and the back panel 113. The first adhesive film layer 1141 and the second adhesive film layer 1142 can also provide a certain support and protection for the battery layer 111, ensuring that the photovoltaic module has good mechanical strength and reducing the impact of hail, wind, mechanical vibration and other conditions.

[0085] This embodiment does not limit the structure of the battery cell 1111. The types of battery cells 1111 include, but are not limited to, passivated emitter rear cell (PERC), tunnel oxide passivated contact (TOPCon), intrinsic thin-film heterojunction (HJT), interdigitated back contact (IBC), perovskite cells, etc.

[0086] For PERC cells, along their thickness direction, the PERC cell sequentially includes a front-surface silver electrode, a front-surface silicon nitride passivation layer, a phosphorus emitter layer, a P-type substrate silicon layer, a localized aluminum back field, a metallic aluminum back electrode, and a back passivation layer (Al2O3 / SiNx). PERC cells use a passivation film to passivate the back side, replacing the all-aluminum back field, enhancing light reflection within the silicon substrate, reducing the recombination rate on the back side, and improving the cell efficiency by 0.5%-1%.

[0087] For a TOPCon cell, along its thickness direction, it sequentially comprises a silver electrode, a front-surface silicon nitride passivation layer, a boron-doped emitter, an N-type substrate silicon layer, a diffused doped layer, an ultrathin silicon oxide layer, doped polycrystalline silicon, silicon nitride, and the silver electrode. The back of the cell consists of an ultrathin silicon oxide layer (1nm–2nm) and a phosphorus-doped microcrystalline amorphous mixed Si film, which together form a passivation contact structure. This structure blocks minority carrier recombination, increasing the cell's open-circuit voltage and short-circuit current. The ultrathin oxide layer allows majority carrier electrons to tunnel into the polycrystalline silicon layer while simultaneously blocking minority carrier recombination. The excellent passivation effect of the ultrathin silicon oxide and heavily doped silicon film causes band bending on the silicon wafer surface, creating a field passivation effect. This significantly increases the probability of electron tunneling, reduces contact resistance, and improves the cell's open-circuit voltage and short-circuit current, thereby enhancing the cell's conversion efficiency.

[0088] For an HJT cell, along its thickness direction, the HJT cell sequentially includes a front low-temperature silver electrode, a front conductive film, an N-type amorphous silicon film, an intrinsic amorphous silicon film, an N-type substrate silicon layer, an intrinsic amorphous silicon film, a P-type amorphous silicon film, a back conductive film, and a back low-temperature silver electrode.

[0089] For an IBC cell, along its thickness direction, it sequentially includes a silicon nitride inversion layer, an N+ front surface field, an N-type substrate silicon layer, a P+ emitter, an N+ back field, an aluminum oxide passivation layer, a silicon nitride antireflection layer, and a silver electrode. IBC cells utilize ion implantation technology to obtain P- and N-regions with good uniformity and precisely controllable junction depth. The absence of grid lines on the front side eliminates light-blocking current loss from the metal electrodes, maximizing the utilization of incident photons and improving short-circuit current by approximately 7% compared to conventional solar cells. Due to its back-contact structure, grid line shading is not a concern, allowing for a wider grid line ratio, thus reducing series resistance and achieving a high fill factor. Optimized design of surface passivation and light-trapping structures can be achieved, resulting in lower front surface recombination rates and surface reflection.

[0090] For a perovskite solar cell, along its thickness direction, it sequentially comprises a substrate material, a conductive thin film, an electron transport layer (titanium dioxide), a perovskite absorption layer (hole transport layer), and a metal cathode. Perovskite materials possess a high light absorption coefficient and a long carrier diffusion distance. After the photons absorbed by the perovskite material are converted into electrons, they are easily collected by the electrodes with minimal loss, thus generating high photogenerated voltage and current, resulting in high photoelectric conversion efficiency.

[0091] The support bracket 200 is installed on the back surface of the photovoltaic module 100 and also serves to provide support for the photovoltaic module 100 to improve its structural rigidity. When the photovoltaic module 100 is subjected to an upward or downward force along its height direction Z (i.e., when the photovoltaic module 100 is under tension or compression), the support bracket 200 can reduce the deformation of the photovoltaic module 100 in its height direction Z and transfer the local load on the photovoltaic module 100 to other areas of the photovoltaic module 100 along the length direction Y of the support bracket 200, thereby increasing the stress-bearing area of ​​the photovoltaic module 100 and reducing the load per unit area of ​​the photovoltaic module 100. This prevents the photovoltaic module 100 from being damaged due to stress concentration. Therefore, installing the support bracket 200 is beneficial to improving the load-bearing performance of the photovoltaic module 100, thereby improving the photovoltaic module 100's resistance to trampling and wind uplift.

[0092] Specifically, the length direction Y of the support bracket 200 can be perpendicular to the width direction X of the photovoltaic module 100. That is, the long side of the support bracket 200 is parallel to the long side of the photovoltaic module 100, and the short side of the support bracket 200 is parallel to the short side of the photovoltaic module 100. This increases the contact area between the support bracket 200 and the photovoltaic module 100, thereby improving the support effect of the support bracket 200 on the photovoltaic module 100 and further enhancing the load-bearing capacity of the photovoltaic module 100. Figure 4 As shown, along the width direction X of the photovoltaic module 100, the distance between the center point of the support 200 and the edge of the photovoltaic module 100 is W1, and the width of the photovoltaic module 100 is W2, where 0.15 ≤ W1:W2 ≤ 0.25. Specifically, the value of W1:W2 can be 0.15, 0.16, 0.17, 0.18, 0.19, 0.2, 0.21, 0.22, 0.23, 0.24, or 0.25, or other values ​​within the above range; this embodiment does not impose any restrictions on this.

[0093] If the value of W1:W2 is too small (e.g., less than 0.15), the bracket 200 is too close to the edge of the photovoltaic module 100 in the width direction X, resulting in an excessively large cantilever area of ​​the photovoltaic module 100. When the photovoltaic module 100 is under tension or compression, the deformation in its height direction Z is large, making it prone to warping and hindering the improvement of the photovoltaic module 100's resistance to trampling and wind uplift. If the value of W1:W2 is too large (e.g., greater than 0.25), the bracket 200 is too far from the edge of the photovoltaic module 100 in the width direction X, resulting in insufficient support for the edge of the photovoltaic module 100. During the installation or use of the photovoltaic module 100, the edge is prone to bending or breakage, which is detrimental to extending the service life of the photovoltaic module 100. Therefore, when the value of W1:W2 satisfies 0.15≤W1:W2≤0.25, the support effect of bracket 200 on photovoltaic module 100 is optimal, the stress effect of photovoltaic module 100 is optimal, which is conducive to further improving the load performance of photovoltaic module 100, thereby improving the resistance to trampling and wind uplift of photovoltaic module 100, and extending the service life of photovoltaic module 100.

[0094] Furthermore, in order to improve the support effect of the bracket 200, the photovoltaic component may include multiple brackets 200. The multiple brackets 200 are arranged at intervals along the width direction X of the photovoltaic module 100, which can further increase the stress area of ​​the photovoltaic module 100, reduce the cantilever area of ​​the photovoltaic module 100, and effectively improve the structural rigidity of the photovoltaic module 100. The spacing between any two adjacent brackets 200 can be the same or different according to actual use requirements. This application does not limit this.

[0095] In one specific implementation, such as Figure 5 and Figure 6 As shown, the bracket 200 includes a first bracket 1 and a second bracket 2. The first bracket 1 includes a first part 11, a second part 12, and a third part 13. The first part 11 is used to connect with the backlight surface of the photovoltaic module 100 to achieve a fixed connection between the bracket 200 and the photovoltaic module 100. Along the height direction Z of the bracket 200, the first part 11 and the third part 13 are respectively connected to the two ends of the second part 12. The first part 11, the second part 12, and the third part 13 form a receiving cavity 14, which has an opening in the width direction X of the bracket 200. The second bracket 2 includes a main body 21. The second bracket 2 can slide with the first bracket 1 along the width direction X of the bracket 200 so that the main body 21 is detachably connected to the receiving cavity 14.

[0096] In this embodiment, the first support component 1 and the second support component 2 are separate structures. The first support component 1 can be pre-fixed to the back surface of the photovoltaic module 100 in the factory to ensure the connection quality between the first support component 1 and the photovoltaic module 100. The second support component 2 can be fixedly connected to the ground or building roof at the installation site. Then, through the sliding connection between the first support component 1 and the second support component 2, the photovoltaic module 100 is installed on the ground or building roof, which helps to improve the installation efficiency and installation quality of the photovoltaic module 100 during on-site installation. Figure 5 As shown, the first support member 1 is a C-shaped structure with an opening along the width direction X of the support 200. The first support member 1 and the second support member 2 are slidably connected along the width direction X of the support 200. Compared with the sliding connection along the length direction Y of the support 200, the sliding stroke is shorter, making operation more convenient and improving the installation efficiency of the photovoltaic module 100. When the photovoltaic module 100 is installed on a sloping roof, the opening direction of the first support member 1 should face the eaves. During installation, the second support member 2 can be fixed on the roof first, and then the photovoltaic module 100 with the wires connected can be placed flat on top of the second support member 2. The receiving cavity 14 is aligned with the main body 21. Then, the worker can stand below the photovoltaic module 100 and pull the photovoltaic module 100 downwards along the eaves, so that the first support member 1 wraps around the main body 21 to complete the connection between the first support member 1 and the second support member 2, thereby fixing the photovoltaic module 100 on the roof. Furthermore, since the main body 21 is connected to the receiving cavity 14, the first support member 1 and the second support member 2 can be mutually positioned in the height direction Z of the support 200, which is beneficial to improving the installation stability and wind resistance of the photovoltaic module 100.

[0097] When using the aforementioned split-type bracket 200 to install photovoltaic modules 100, workers do not need to stand on the surface of the photovoltaic modules 100 for installation, avoiding trampling on the photovoltaic modules. This means the bracket 200 is suitable not only for installing ordinary photovoltaic modules 100 but also for installing lightweight photovoltaic modules 100 that should not be stepped on, making it more versatile. Furthermore, using the split-type bracket 200 to install photovoltaic modules 100 allows for two consecutive rows of photovoltaic modules 100 along the height of the roof, reducing the number of maintenance access routes and increasing the installed capacity of photovoltaic modules 100 per unit area, thus improving the power generation capacity of the photovoltaic system.

[0098] Furthermore, along the length Y of the bracket 200, the lengths of the first bracket 1 and the second bracket 2 should be greater than the length of the photovoltaic module 100, and the portions of the first bracket 1 and the second bracket 2 extending beyond both ends of the photovoltaic module 100 should be fixedly connected by locking members 4. This prevents the first bracket 1 and the second bracket 2 from sliding relative to each other along the width X of the bracket 200 during use, thereby improving the installation stability and reliability of the photovoltaic module 100. The locking member 4 can be a bolt, screw, pin, or other parts; this embodiment does not impose any limitations on this. The material of the bracket 200 can be steel, aluminum alloy, or polymer materials, etc.; this embodiment does not impose any limitations on this either.

[0099] In one specific implementation, such as Figure 6 As shown, along the height direction Z of the bracket 200, the height of the first bracket 1 is H1, 15mm≤H1≤20mm. H1 can specifically be 15mm, 15.5mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm or 20mm, or other values ​​within the above range. This example does not impose any restrictions on this.

[0100] If H1 is too small (e.g., less than 15mm), the size of the receiving cavity 14 in the height direction Z of the bracket 200 will be too small, making it difficult for the main body 21 to extend into the receiving cavity 14, thus affecting the connection efficiency between the first bracket 1 and the second bracket 2. The back surface of the photovoltaic module 100 is usually also equipped with a junction box, the size of which in the height direction of the bracket 200 is no greater than 20mm. If H1 is too large (e.g., greater than 20mm), the height of the first bracket 1 will exceed the height of the junction box. Since the first bracket 1 is fixedly connected to the photovoltaic module 100 as a whole before leaving the factory, the whole assembly will require more space, making packaging and transportation inconvenient. Therefore, when the height H1 of the first bracket 1 is 15mm to 20mm, the connection efficiency between the first bracket 1 and the second bracket 2 is ensured, while the space occupied by the photovoltaic module 100 and the first bracket 1 as a whole is reduced, saving packaging materials and making packaging and transportation easier.

[0101] In one specific implementation, such as Figure 6 and Figure 7As shown, the first bracket 1 further includes a first guide portion 15, which is fixedly connected to the end of the first part 11 away from the second part 12 along the width direction X of the bracket 200. The first guide portion 15 is oriented away from the first part 11 along the width direction X of the bracket 200, and the height difference between the first guide portion 15 and the backlight surface gradually decreases, that is, the first guide portion 15 is inclined upward relative to the first part 11; and / or, the first bracket 1 further includes a second guide portion 16, which is fixedly connected to the end of the third part 13 away from the second part 12 along the width direction X of the bracket 200. The second guide portion 16 is oriented away from the third part 13 along the width direction X of the bracket 200, and the height difference between the second guide portion 16 and the backlight surface gradually increases, that is, the second guide portion 16 is inclined downward relative to the third part 13.

[0102] In this embodiment, when the first support member 1 and the second support member 2 are slidably connected, it is necessary to first ensure that the main body 21 can extend into the receiving cavity 14. At this time, if the main body 21 is in a higher position relative to the receiving cavity 14 in the height direction Z of the support 200, the first guide part 15 can slide and cooperate with the main body 21 during the sliding process of the first support member 1 relative to the second support member 2, driving the first support member 1 to move upward along the height direction Z of the support 200 towards the main body 21, so as to ensure that the main body 21 can smoothly enter the receiving cavity 14, which is beneficial to improving the connection efficiency of the first support member 1 and the second support member 2, thereby improving the installation efficiency of the photovoltaic module 100. Similarly, if the main body 21 is positioned lower relative to the receiving cavity 14 in the height direction Z of the bracket 200, the second guide part 16 can slide and engage with the main body 21 during the sliding of the first bracket 1 relative to the second bracket 2, driving the first bracket 1 downward along the height direction Z of the bracket 200 towards the main body 21. This ensures that the main body 21 can smoothly enter the receiving cavity 14, which is beneficial to improving the connection efficiency between the first bracket 1 and the second bracket 2, thereby improving the installation efficiency of the photovoltaic module 100. When the first bracket 1 is simultaneously provided with the first guide part 15 and the second guide part 16, the alignment efficiency between the receiving cavity 14 and the main body 21 can be improved, thereby further improving the installation efficiency of the photovoltaic module 100.

[0103] In one specific embodiment, the first support member 1 can be fixed to the back surface of the photovoltaic module 100 by adhesive bonding, such as... Figure 6 As shown, along the height direction Z of the bracket 200, the first part 11 is provided with a receiving groove 17 on the side facing the backlight surface. The receiving groove 17 is used to receive the adhesive 3. The first part 11 is bonded and fixed to the backlight surface by the adhesive 3.

[0104] In this embodiment, along the width direction X of the bracket 200, a limiting wall 171 extending upward along the height direction Z of the bracket 200 is provided at the end of the first part 11 away from the first guide part 15. The limiting wall 171, the first guide part 15, and the first part 11 communicate with the receiving groove 17. The limiting wall 171 and the first guide part 15 can limit the adhesive 3 along the width direction X of the bracket 200, reducing the risk of adhesive 3 overflowing, ensuring the amount and thickness of adhesive 3 applied, thereby improving the bonding reliability between the first bracket 1 and the photovoltaic module 100. The adhesive 3 should be continuously provided along the length direction Y of the bracket 200 to ensure that the first bracket 1 can be subjected to uniform force, reducing the risk of damage to the photovoltaic module 100 due to stress concentration. Along the length Y of the bracket 200, a certain distance should be maintained between the end of the adhesive 3 and the end of the photovoltaic module 100, that is, a certain amount of overflow space should be reserved at both ends of the photovoltaic module 100 to reduce the situation where the adhesive 3 overflows to the outside of the photovoltaic module 100.

[0105] The adhesive 3 can be a structural adhesive, specifically one of the following: high-performance silicone structural adhesive, neutral transparent silicone structural adhesive, epoxy resin structural adhesive, polyurethane structural adhesive, acrylic structural adhesive, silicone rubber structural adhesive, and polyamide structural adhesive. It can also be other structural adhesives, and this embodiment does not limit it.

[0106] In one specific implementation, such as Figure 5 and Figure 6 As shown, along the width direction X of the bracket 200, a support plane 151 is provided at the end of the first guide portion 15 away from the first portion 11. The support plane 151 abuts against the backlight surface along the height direction Z of the bracket 200, which is beneficial to improving the support effect of the first bracket 1 on the photovoltaic module 100. Moreover, by providing the support plane 151, the contact area between the first guide portion 15 and the photovoltaic module 100 can be increased, reducing the risk of stress concentration when the photovoltaic module 100 is pressed downward and comes into contact with the first guide portion 15. This is beneficial to improving the installation stability of the photovoltaic module 100 and extending the service life of the photovoltaic module 100.

[0107] In one specific implementation, such as Figure 8 As shown, the main body 21 has a first surface 211 and a second surface 212 disposed opposite to each other along the height direction Z of the bracket 200. The first surface 211 is the side surface of the main body 21 close to the backlight surface of the photovoltaic module 100, and the second surface 212 is the side surface of the main body 21 away from the backlight surface of the photovoltaic module 100. The first surface 211 is provided with a first protrusion 23, which protrudes outward along the height direction Z of the bracket 200; and / or, the second surface 212 is provided with a second protrusion 24, which protrudes outward along the height direction Z of the bracket 200.

[0108] In this embodiment, the first protrusion 23 is used to slide and engage with the inner surface of the first part 11 during the sliding connection between the first support member 1 and the second support member 2, thereby reducing the contact area between the main body part 21 and the first part 11. This reduces the frictional resistance between the main body part 21 and the first part 11, making the connection between the first support member 1 and the second support member 2 easier and improving the installation efficiency of the photovoltaic module 100. Similarly, the second protrusion 24 is used to slide and engage with the inner surface of the third part 13 during the sliding connection between the first support member 1 and the second support member 2, thereby reducing the contact area between the main body part 21 and the third part 13. This reduces the frictional resistance between the main body part 21 and the third part 13, making the connection between the first support member 1 and the second support member 2 easier and improving the installation efficiency of the photovoltaic module 100. When the first surface 211 is provided with the first protrusion 23 and the second surface 212 is provided with the second protrusion 24, the sliding friction between the main body part 21 and the first support member 1 can be further reduced, thereby further improving the installation efficiency of the photovoltaic module 100.

[0109] Specifically, along the width direction X of the bracket 200, a plurality of first protrusions 23 may be provided at intervals on the first surface 211, and a plurality of second protrusions 24 may be provided at intervals on the second surface 212. In this embodiment, the number of first protrusions 23 and second protrusions 24 is not limited.

[0110] Furthermore, such as Figure 8 As shown, along the width direction X of the bracket 200, a first guide slope 211a is provided on the first surface 211 near the end of the second part 12; and / or, along the width direction X of the bracket 200, a second guide slope 212a is provided on the second surface 212 near the end of the second part 12.

[0111] In this embodiment, the first guide slope 211a is used to slide and engage with the first guide portion 15 and / or the first portion 11 during the sliding connection of the first support member 1 and the second support member 2, so as to guide the movement of the first support member 1 in the height direction Z of the support 200, driving the first support member 1 upward along the height direction Z of the support 200 and approaching the main body portion 21, ensuring that the main body portion 21 can smoothly enter the receiving cavity 14, which is beneficial to improving the connection efficiency of the first support member 1 and the second support member 2, thereby improving the installation efficiency of the photovoltaic module 100. Similarly, the second guide slope 212a is used to slide and engage with the second guide portion 16 and / or the third portion 13 during the sliding connection of the first support member 1 and the second support member 2, so as to guide the movement of the first support member 1 in the height direction Z of the support 200, driving the first support member 1 downward along the height direction Z of the support 200 and approaching the main body portion 21, ensuring that the main body portion 21 can smoothly enter the receiving cavity 14, which is beneficial to improving the connection efficiency of the first support member 1 and the second support member 2, thereby improving the installation efficiency of the photovoltaic module 100. When the first surface 211 is provided with the first guide slope 211a and the second surface 212 is provided with the second guide slope 212a, the efficiency of the main body 21 extending into the receiving cavity 14 can be improved through the sliding cooperation between the first bracket 1 and the first guide slope 211a and the second guide slope 212a, thereby further improving the installation efficiency of the photovoltaic module 100.

[0112] like Figure 1 As shown, the photovoltaic component provided in this embodiment also includes color steel tiles 400 and clamps 300. Multiple color steel tiles 400 are installed on the ground or the main building structure via supports. The photovoltaic module 100 is installed on the color steel tiles 400 via the clamps 300, facilitating the use of solar energy to generate electricity to meet daily usage needs. The main building structure includes, but is not limited to, the roofs and walls of production facilities such as factories and warehouses. This application uses a roof as an example for illustration. Figure 9 As shown, the color steel tile 400 includes a male rib 410 and a female rib 420 arranged opposite each other along its own width direction. The male rib 410 is used to form a locking structure with the female rib 420 of the adjacent color steel tile 400. Figure 10 As shown, the clamp 300 includes a first clamping portion 310 and a second clamping portion 320 disposed opposite to each other along its own width direction, with a clamping cavity formed between them. The locking edge structure is accommodated in the clamping cavity and is clamped by the first clamping portion 310 and the second clamping portion 320 along the width direction of the clamp 300. The specific structure of the first clamping portion 310 and the second clamping portion 320 can be adjusted according to the specific shape of the locking edge structure; it can be an arc structure or a planar structure. This embodiment does not impose any limitations on this.

[0113] Specifically, at least one of the first clamping part 310 and the second clamping part 320 is connected to the bracket 200 by a fastener 500, such as Figure 5 and 8 As shown, the second bracket 2 also includes a mounting portion 22. Along the width direction X of the bracket 200, the mounting portion 22 is fixedly connected to the side of the main body 21 away from the receiving cavity 14. Along the height direction Z of the bracket 200, the end of the mounting portion 22 away from the main body 21 is provided with a downwardly opening limiting groove 221, which is used to accommodate the fastener 500. Along the height direction Z of the bracket 200, one end of the fastener 500 is installed in the limiting groove 221, and the other end can extend out from the opening of the limiting groove 221 and be fixedly connected to the first clamping portion 310 or the second clamping portion 320, so that the photovoltaic module 100 is installed onto the color steel tile 400 through the bracket 200 and the clamp 300. Specifically, the fastener 500 can be a bolt, screw, or pin, or other fastening parts; this embodiment does not limit this.

[0114] like Figure 7 As shown, this embodiment also provides another structure for the mounting part 22. The mounting part 22 is provided with an extension platform 222. Along the height direction Z of the bracket 200, the fastener 500 can directly pass through the extension platform 222 and be fixedly connected to the first clamping part 310 or the second clamping part 320, so that the photovoltaic module 100 can be installed on the color steel tile 400 through the bracket 200 and the clamp 300.

[0115] like Figures 7 to 9 As shown, the main body 21 is also provided with a first cavity 213, and / or the mounting part 22 is also provided with a second cavity 223. On the one hand, this can reduce the weight of the second support member 2 and achieve the lightweighting of the second support member 2. On the other hand, it can also help improve the bending resistance of the second support member 2, thereby improving the structural strength of the second support member 2.

[0116] In this embodiment, as Figure 1 As shown, the length direction Y of the bracket 200 can be installed perpendicular to the length direction of the locking edge structure. Compared to the installation method where the length direction Y of the bracket 200 is parallel to the length direction of the locking edge structure, there is no need to consider whether the bracket 200 and the locking edge structure are aligned along the height direction Z of the bracket 200. That is, when the length direction Y of the bracket 200 can be installed perpendicular to the length direction of the locking edge structure, the bracket 200 can adapt to different widths of color steel roofing sheets 400, without restricting the shape and structure of the color steel roofing sheets 400, thus offering high flexibility.

[0117] Furthermore, along the width direction X of the photovoltaic module 100, there are no supports 200 at both ends of the photovoltaic module 100's edges. Therefore, the edges are prone to large deformation when under pressure, which may cause them to come into contact with the edge locking structure. In order to reduce the risk of damage to the photovoltaic module 100 due to stress concentration, a buffer strip can be set on the edge locking structure. The buffer strip can support and buffer the edges and frame 120 of the photovoltaic module 100 along the height direction Z of the support 200, thus preventing the photovoltaic module 100 from directly contacting the edge locking structure.

[0118] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
