Description

Technical Field

[0001] This invention relates to the field of photovoltaic manufacturing technology, and in particular to a rapid installation structure for building-integrated photovoltaics. Background Technology

[0002] With the popularization of green building concepts, building integrated photovoltaic (BIPV, PV stands for Photovoltaic) technology has become an important way for the construction industry to achieve carbon neutrality.

[0003] However, in practical applications, existing BIPV photovoltaic modules are mostly fixed with screws and sealed with structural adhesive. This results in a complex installation structure, long construction period, high cost, and insufficient sealing between the module and the building structure, which can easily lead to fire hazards. Moreover, when photovoltaic modules malfunction, repairs are inconvenient, requiring the removal of large areas of decorative panels or parts of the installation structure. This makes maintenance difficult, can easily damage the modules, is inefficient, and can also affect the normal use of the building. Summary of the Invention

[0004] The technical problem solved by this invention is to provide a rapid installation structure for building-integrated photovoltaics (BIPV) to address the issues of complex installation structures and high maintenance difficulty of BIPV modules.

[0005] In a first aspect, the present invention provides a rapid installation structure for building-integrated photovoltaics, comprising: Trusses are fixed to the main structure of the building; A modular quick-assembly structure is connected to the truss, and the modular quick-assembly structure includes a frame, photovoltaic modules, a first pressure block, and a second pressure block; The first pressure block is connected to the truss, the frame is located on the side of the first pressure block, the frame has an integrally formed first connecting plate and second connecting plate, the first connecting plate abuts against the truss, the second connecting plate is perpendicular to the first connecting plate, the photovoltaic module is connected to the first connecting plate and abuts against the side of the second connecting plate; The second pressure block is engaged on the first pressure block, and the first pressure block abuts against the first connecting plate on the side away from the photovoltaic module on the side facing the truss.

[0006] Beneficial Effects: This invention completes the base installation by fixing the truss to the main building structure and simultaneously sliding the first pressure block onto the truss and moving it to a preset installation point. Then, the first connecting plate of the frame is attached to the truss, and the side of the first connecting plate abuts against the first pressure block; subsequently, the second pressure block is engaged with the first pressure block, and the lower surface of the first pressure block along the Z-direction abuts against the upper surface of the first connecting plate, completing the locking and fixing. This achieves the installation and fixing of the modular quick-installation structure on the truss. The entire on-site installation process of BIPV photovoltaic modules involves no complex procedures, requires less professional expertise from construction personnel, significantly shortens the time spent on high-altitude operations, and is not excessively affected by inclement weather such as rain, effectively improving the construction efficiency of BIPV and thus shortening the construction cycle.

[0007] Furthermore, the separate design of the first and second pressure blocks eliminates the need for bolts during installation and avoids damaging the existing fixing structure during disassembly. The installation and removal of each component do not affect the surrounding photovoltaic modules, pressure blocks, or truss structure. Moreover, when a photovoltaic module malfunctions and needs replacement, simply pull the second pressure block of the corresponding unit from the first pressure block by hand to release the lock, and the faulty photovoltaic module and its frame can be directly removed from the truss. The entire process requires no wrenches, screwdrivers, or other tools, enabling tool-free rapid repair and reducing maintenance costs and photovoltaic module damage rates.

[0008] In one possible implementation, the first pressure block has limiting portions at both ends along the Y direction, each limiting portion having a first bending portion and a second bending portion that bend in sequence, and the truss is at least partially engaged within the installation space formed by the first bending portion and the second bending portion.

[0009] In one possible implementation, the first pressure block has a pair of first protrusions on its surface away from the truss, and the second pressure block is engaged between the pair of first protrusions.

[0010] In one possible implementation, the first pressure block has an inwardly recessed first groove on one side surface facing the truss, and at least one side of the truss abuts against the sidewall of the first groove.

[0011] In one possible implementation, the second pressure block has a second protrusion on each side along the X direction, and the lower end face of the second protrusion along the Z direction abuts against the first connecting plate.

[0012] In one possible implementation, along the X direction, a pair of the second protrusions are misaligned on both sides of the second pressure block.

[0013] In one possible implementation, the modular quick-installation structure further includes an elastic gasket, the second pressure block is a magnetic pressure block, the first pressure block has a first connecting hole, the second pressure block has a first connecting post, and the second pressure block passes through the elastic gasket and the first connecting hole in sequence through the first connecting post, so that the second pressure block is magnetically attached to the first pressure block.

[0014] In one possible implementation, the first connecting plate is provided with a second connecting hole and an adhesive groove, respectively located on both sides of the second connecting plate along the X direction, and the photovoltaic module is bonded to the side of the first connecting plate having the adhesive groove; The end of the second connecting plate away from the first connecting plate has an arc surface that bends toward the photovoltaic module.

[0015] In one possible implementation, the modular quick-installation structure further includes a protective component, which is provided with a plurality of second connecting posts. The second connecting posts are inserted into the second connecting holes on two adjacent first connecting plates and are snapped into the first connecting plates.

[0016] In one possible implementation, the photovoltaic module includes a backsheet, solar cells, and encapsulation glass stacked sequentially, with an adhesive film between the solar cells and the backsheet and between the solar cells and the encapsulation glass; the encapsulation glass has a self-cleaning coating.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] According to embodiments of the present invention, such as Figure 1 and Figure 9 As shown, a rapid installation structure for building-integrated photovoltaics (BIPV) is provided, comprising: a truss 10 fixed to the main building structure; and a modular quick-installation structure connected to the truss 10, the modular quick-installation structure including a frame 100, photovoltaic modules 400, a first pressure block 200, and a second pressure block 300; the first pressure block 200 is connected to the truss 10, the frame 100 is located on the side of the first pressure block 200, the frame 100 has an integrally formed first connecting plate 110 and a second connecting plate 120, the first connecting plate 110 abuts against the truss 10, the second connecting plate 120 is perpendicular to the first connecting plate 110, the photovoltaic module 400 is connected to the first connecting plate 110 and abuts against the side of the second connecting plate 120; the second pressure block 300 is engaged with the first pressure block 200, the side of the first pressure block 200 facing the truss 10 abuts against the side of the first connecting plate 110 away from the photovoltaic module 400.

[0023] In this embodiment, the X direction is the length direction of the rapid installation structure, the Y direction is the width direction of the rapid installation structure, and the Z direction is the height direction of the rapid installation structure. The truss 10 can be made of high-strength extruded aluminum alloy profiles, directly fixed to the building structure, and serves as the universal load-bearing skeleton for the entire rapid installation structure. The truss 10 is equipped with positioning slots and waterproof guide ribs. The internal cavity of the truss 10 can serve as a concealed cable channel, collecting the DC cables of all components and connecting to the electrical shafts inside the building. The truss 10 provides a uniform, flat, and standardized installation reference surface for the rapid installation structure, compensating for unevenness errors in the building structure's base surface; moreover, it can evenly transfer all external forces, such as the self-weight of the photovoltaic modules 400, wind load, and snow load, to the building structure, ensuring the safety of the rapid installation structure.

[0024] like Figures 1 to 4As shown, the modular quick-installation structure is connected to the truss 10 and includes a frame 100, a photovoltaic module 400, a first pressure block 200, and a second pressure block 300. The first pressure block 200 is installed on the truss 10 and matches a positioning slot on the truss 10. When the modular quick-installation structure is not fixed to the truss 10, the first pressure block 200 can be slidably adjusted to change the installation position of the modular quick-installation structure to adapt to different usage scenarios. For example, when the length of the truss 10 is fixed, and the overall size of the photovoltaic module 400 is small, the installation position of the frame 100 is positioned by adjusting the position of the first pressure block 200, so that the frame 100 is installed on the side of the first pressure block 200. Then, the position of the other frame 100 is installed according to the overall size of the photovoltaic module 400 to facilitate the installation of the photovoltaic module 400 onto the frame 100. Alternatively, the photovoltaic module 400 can be installed on a pair of frames 100 first, and then the frame 100 with the photovoltaic module 400 can be set on the side of the first pressing block 200 to achieve the initial installation of the photovoltaic module 400 and the frame 100.

[0025] like Figure 5 and Figure 6 As shown, the frame 100 has an integrally formed first connecting plate 110 and second connecting plate 120. Along the Z-direction, the second connecting plate 120 extends upwards perpendicular to the first connecting plate 110, forming a T-shaped cross-section. The first connecting plate 110 is horizontally attached to the truss 10. The photovoltaic module 400 is mounted on the first connecting plate 110 of the pair of frame 100 at both ends along the X-direction, and both sides of the photovoltaic module 400 abut against the second connecting plate 120 of the pair of frame 100 to achieve the installation and fixation of the photovoltaic module 400. Simultaneously, the second connecting plate 120 acts as a structural reinforcing rib, improving the overall rigidity of the frame 100 and protecting the edges of the photovoltaic module 400 from damage during transportation and installation. The frame 100 is positioned on the side of the first pressure block 200, which restricts the horizontal or vertical displacement of the frame 100, thus providing initial positional constraint on the frame 100.

[0026] like Figures 7 to 9 As shown, after the first pressure block 200 and the frame 100 are both installed on the truss 10, the second pressure block 300 is engaged with the first pressure block 200, and the second pressure block 300 abuts against the upper surface of the first connecting plate 110 on the side away from the photovoltaic module 400 along the Z direction towards the truss 10, thereby fixing the frame 100 to the truss 10 and preventing the frame 100 from coming off the truss 10. The second pressure block 300 and the first pressure block 200 form a double fixation, ensuring the stability of the rapid installation structure under wind and snow loads.

[0027] In this embodiment of the invention, the truss 10 is fixed to the main building structure, and the first pressure block 200 is slidably placed on the truss 10 and moved to a preset installation point, thereby completing the installation of the base. Then, the first connecting plate 110 of the frame 100 is attached to the truss 10, and the side of the first connecting plate 110 abuts against the first pressure block 200; then, the second pressure block 300 is snapped onto the first pressure block 200, and the lower surface of the first pressure block 200 along the Z direction abuts against the upper surface of the first connecting plate 110, completing the locking and fixing, thus realizing the installation and fixing of the modular quick-installation structure on the truss 10. The entire on-site installation process of the BIPV photovoltaic module 400 has no complex procedures, requires less professional expertise from construction personnel, significantly shortens the time spent on high-altitude operations, and is not excessively affected by rainy or other inclement weather, effectively improving the construction efficiency of BIPV and thus shortening the construction cycle.

[0028] Furthermore, the separate design of the first pressure block 200 and the second pressure block 300 eliminates the need for bolts during installation and avoids damaging the original fixing structure during disassembly. The installation and removal of each component do not affect the surrounding photovoltaic modules 400, pressure blocks, and truss 10 structures. Moreover, when a photovoltaic module 400 malfunctions and needs to be replaced, the second pressure block 300 of the corresponding unit can be manually pulled off the first pressure block 200 to release the lock, allowing the faulty photovoltaic module 400 and frame 100 to be directly removed from the truss 10. The entire process requires no wrenches, screwdrivers, or any other tools, enabling tool-free rapid repair and reducing maintenance costs and the damage rate of the photovoltaic modules 400.

[0029] like Figure 10 and Figure 11 As shown, in one embodiment, the first pressure block 200 is provided with limiting portions 220 at both ends along the Y direction. The limiting portions 220 have a first bending portion 221 and a second bending portion 222 that are bent in sequence. The truss 10 is at least partially locked in the installation space formed by the first bending portion 221 and the second bending portion 222.

[0030] In this embodiment, along the Z-direction, the lower surface of the first pressure block 200 is attached to the upper surface of the truss 10. A limiting portion 220 is provided at each end of the first pressure block 200 along the Y-direction, allowing the limiting portion 220 to engage with the truss 10, thereby fixing the first pressure block 200 to the truss 10. Specifically, the limiting portion 220 has a first bending portion 221 and a second bending portion 222 that are bent sequentially. The first bending portion 221 is a vertical limiting section, bending vertically from the end of the first pressure block 200 along the Y-direction towards the truss 10 along the Z-direction to form a vertical retaining edge. The sidewall of the truss 10 along the Y-direction can be attached to the inner surface of the first bending portion 221 to restrict the first pressure block 200 from moving along the Y-direction. It is understood that only one sidewall of the truss 10 along the Y-direction can be attached to the inner surface of the first bending portion 221; the specific arrangement can be determined according to actual usage requirements.

[0031] The second bend 222 bends horizontally from the end of the first bend 221 towards the center of the truss 10 along the Y direction, forming a transverse hook-shaped edge. The upper surface of the second bend 222 along the Z direction hooks onto the lower surface of the truss 10 or the bottom surface of the flange of the truss 10, forming an opposing clamping with the lower surface of the first pressure block 200. Finally, the main body of the first pressure block 200, the first bend 221, and the second bend 222 together enclose a C-shaped mounting slot with an opening facing the center of the truss 10. The flanges and / or side walls of the truss 10, and other stress-bearing parts, are precisely clamped into the slot, so that at least part of the truss 10 is clamped in the installation space, thereby achieving the installation and fixation of the first pressure block 200 on the truss 10. During installation, the first pressure block 200 is directly slid into the designated position from the end of the truss 10 along the X direction, completing the positioning and pre-fixation in one step without drilling or tightening bolts, making the operation simple. The hook edge of the second bend 222 hooks onto the lower surface of the truss 10, restricting the upward displacement of the first pressure block 200, directly bearing the wind suction load, achieving rigid pull-out resistance, and improving the connection stability of the first pressure block 200 on the truss 10.

[0032] like Figure 10 and Figure 11 As shown, in one embodiment, a pair of first protrusions 210 are provided on the surface of the first pressing block 200 away from the truss 10, and the second pressing block 300 is engaged between the pair of first protrusions 210.

[0033] In this embodiment, a pair of first protrusions 210 are spaced apart on the upper surface of the first pressing block 200 along the Z direction. The first protrusions 210 extend from the upper surface of the first pressing block 200 away from the first pressing block 200 and are integrally formed with the first pressing block 200. The vertically extending sections of the pair of first protrusions 210 form the vertical sidewalls of the slot to restrict the displacement of the second pressing block 300 along the Y direction. An arc-shaped chamfer is provided at the top of the first protrusion 210 and at the entrance of the slot to facilitate the quick insertion of the second pressing block 300 and reduce the difficulty of alignment during on-site operation. Furthermore, the second pressing block 300 can be interference-fitted with the slot, and the first pressing block 200 and the second pressing block 300 can be fixedly connected by friction. Alternatively, the top of the first protrusion 210 can be inclined towards the center of the slot, so that the first protrusion 210 and the first pressing block 200 are squeezed together, reducing the risk of the second pressing block 300 falling off or shifting during installation. By locking the second pressure block 300 into the slot formed by a pair of first protrusions 210, locking and unlocking can be completed by hand without any small parts that are easy to fall off, eliminating the need for tools, effectively shortening the on-site installation cycle, and significantly reducing the safety risks of working at heights.

[0034] In one embodiment, the first pressure block 200 has an inwardly recessed first groove 230 on one side surface facing the truss 10, and at least one side of the truss 10 abuts against the side wall of the first groove 230.

[0035] In this embodiment, the first groove 230 is formed on the side of the first pressure block 200 facing the truss 10 along the Z direction, recessed inward from the lower surface of the first pressure block 200. The bottom surface of the first groove 230 fits against the upper surface of the truss 10, bearing the pressure of the vertical self-weight and snow load transmitted by the photovoltaic module 400 and the frame 100; the two inner sidewalls of the groove 230 along the Y direction are perpendicular to the bottom surface of the groove 230 and are used to abut against the side of the truss 10, thereby limiting the first pressure block 200 along the Y direction; an arc-shaped chamfer is provided at the entrance of the groove 230 to facilitate the quick insertion of the first pressure block 200 into the truss 10, reducing the difficulty of on-site alignment. Both sides of the truss 10 can abut against the sidewall of the groove 230, or one side of the truss 10 can abut against the sidewall of the groove 230 and the other side can abut against the first bend 221. This also achieves the limitation of the first pressure block 200 on the truss 10, reducing the risk of the first pressure block 200 moving along the Y direction on the truss 10. By setting the first groove 230, during installation, the first pressure block 200 can be directly aligned with the groove 230 and slid into the truss 10, thereby completing the installation positioning between the first pressure block 200 and the truss 10. This can be operated by one person with one hand, further improving the installation efficiency of the modular quick-assembly structure.

[0036] like Figure 7 and Figure 9As shown, in one embodiment, the second pressing block 300 has second protrusions 310 on both sides along the X direction, and the lower end face of the second protrusions 310 along the Z direction abuts against the first connecting plate 110.

[0037] In this embodiment, a pair of second protrusions 310 are provided on the second pressure block 300. Along the X direction, the pair of second protrusions 310 are arranged opposite to each other on both sides of the second pressure block 300 and extend from the side of the second pressure block 300 away from the second pressure block 300. When installing the second pressure block 300, it can be pressed into the slot by hand without additional installation tools. After the second pressure block 300 is engaged with the slot of the first pressure block 200 and locked in place, the lower end face of the second protrusion 310 along the Z direction just abuts against the upper surface of the first connecting plate 110 of the frame 100, forming a stable vertical rigid pressing. During replacement, the second pressure block 300 can be pulled upwards by hand, and the second protrusion 310 will simultaneously detach from the first connecting plate 110 of the faulty component, thus allowing the faulty component to be pulled out directly. The entire process does not involve touching or disassembling the fasteners of adjacent photovoltaic modules 400. After replacing the new prefabricated photovoltaic module 400, the second pressure block 300 is pressed back, which simultaneously completes the locking and pressing. The entire process is tool-free, effectively reducing the risk of chain damage, thereby reducing maintenance costs and the secondary damage rate of photovoltaic modules 400.

[0038] It is understandable that the second protrusions 310 on both sides of the second pressure block 300 can simultaneously press the first connecting plates 110 of the two frame 100, which can reduce the number of second pressure blocks 300 used, thereby further optimizing the structural complexity and installation process of the modular quick-installation structure.

[0039] like Figure 7 and Figure 9 As shown, in one embodiment, along the X direction, a pair of second protrusions 310 are offset on both sides of the second pressure block 300. Specifically, the pair of second protrusions 310 are offset on both sides of the second pressure block 300 along the X direction, such that one end face of the second protrusion 310 along the Y direction is flush with the end face of the second pressure block 300, thereby positioning the pair of second protrusions 310 opposite each other at the ends of the second pressure block 300 along the Y direction. By offsetting the second protrusions 310, the frame 100 on both sides of the first pressure block 200 is prevented from transmitting force to the second pressure block 300 along the same force line, thereby avoiding stress concentration on the second pressure block 300 and reducing the risk of breakage of the second pressure block 300.

[0040] In one embodiment, the modular quick-installation structure further includes an elastic gasket 600, a second pressure block 300 being a magnetic pressure block, a first connection hole 240 on the first pressure block 200, and a first connection post 320 on the second pressure block 300. The second pressure block 300 passes through the elastic gasket 600 and the first connection hole 240 in sequence via the first connection post 320, and is magnetically attracted to the first pressure block 200.

[0041] In this embodiment, the second pressing block 300 is a magnetic pressing block that can magnetically engage with the first pressing block 200. The first pressing block 200 has a first connecting hole 240 located between a pair of first protrusions 210; the second pressing block 300 has a first connecting post 320 that matches the first connecting hole 240; and an elastic gasket 600 is provided between the first pressing block 200 and the second pressing block 300. When the first pressure block 200 needs to be installed onto the second pressure block 300, the first connecting post 320 of the second pressure block 300 passes through the elastic washer 600, thus pre-fitting the elastic washer 600 onto the first connecting post 320 of the second pressure block 300; then align the first connecting post 320 with the first connecting hole 240 of the first pressure block 200, and gently place it downwards, so that the first connecting post 320 passes through the elastic washer 600 and the first connecting hole 240 in sequence; when the first connecting post 320 is inserted into place, the magnetic attraction surfaces of the second pressure block 300 and the first pressure block 200 are in contact, and the permanent magnet automatically generates a strong attraction force, completing the fully automatic locking; at the same time, the elastic washer 600 is uniformly compressed, providing a continuous reverse pre-tightening force, eliminating the fit gap between the first pressure block 200 and the second pressure block 300, so that the locking state is without loosening or abnormal noise.

[0042] When a component fails and needs to be replaced, simply pull the second pressure block 300 upwards by hand to overcome the magnetic attraction and completely pull the first connecting post 320 out of the first connecting hole 240. No additional tools are required throughout the process, which effectively improves the installation and maintenance efficiency of the modular quick-installation structure.

[0043] like Figure 5 , Figure 6 , Figure 12 and Figure 13 As shown, in one embodiment, the first connecting plate 110 is provided with a second connecting hole 111 and an adhesive groove 112, respectively located on both sides of the second connecting plate 120 along the X direction. The photovoltaic module 400 is bonded to the side of the first connecting plate 110 with the adhesive groove 112. The end of the second connecting plate 120 away from the first connecting plate 110 has an arc surface 121 that bends toward the photovoltaic module 400. Further, the modular quick-installation structure also includes a protective component, which is provided with a plurality of second connecting posts 510. The second connecting posts 510 are inserted into the second connecting holes 111 on two adjacent first connecting plates 110 and are snapped into the first connecting plates 110.

[0044] In this embodiment, the first connecting plate 110 is provided with a second connecting hole 111 and an adhesive groove 112, which are located on both sides of the second connecting plate 120 along the X direction. The adhesive groove 112 extends along the Y direction of the first connecting plate 110 and is close to the photovoltaic module 400, so that the back of the photovoltaic module 400 is bonded to the first connecting plate 110 with structural adhesive. The adhesive groove 112 is adapted to the rheological properties of the special structural adhesive for the photovoltaic module 400, which ensures the amount of adhesive stored and reduces the risk of adhesive overflow. The adhesive groove 112 is arc-shaped, which can ensure that the structural adhesive uniformly fills the interface gap between the photovoltaic module 400 and the first connecting plate 110, avoids adhesive layer accumulation or local adhesive deficiency, and ensures that the adhesive layer thickness is uniform, thereby improving the bonding strength between the photovoltaic module 400 and the first connecting plate 110.

[0045] At the end of the second connecting plate 120 furthest from the first connecting plate 110, there is an arc surface 121 that curves toward the photovoltaic module 400. The arc surface 121 fits against the side of the photovoltaic module 400, forming a continuous adhesive sealing surface. This optimizes the bonding interface between the photovoltaic module 400 and the second connecting plate 120, expanding the bonding interface from line contact to surface contact, effectively increasing the contact area between the second connecting plate 120 and the photovoltaic module 400, making the adhesive layer distribution more uniform, thereby improving the bonding strength and solving the problem of easy delamination in traditional flat bonding. At the same time, the arc surface 121 increases the contact angle between dust and the surface of the photovoltaic module 400, and the rainwater washes away the dust, creating a guiding effect, reducing the dust accumulation rate and the frequency of manual cleaning; the arc design also conforms to the curved surface requirements of building facades, eliminating the dust and mud bands that accumulate on the traditional module frame 100, and improving the building's aesthetics. The cooperation between the adhesive groove 112 and the arc surface 121 forms a double seal, effectively preventing rainwater and dust from seeping into the modular quick-installation structure, which is beneficial to improving the reliability of the photovoltaic module 400.

[0046] Furthermore, the protective component can be a protective plate 500, and the protective plate 500 can be interference-fitted with the frame 100. A plurality of second connecting posts 510 are provided on the protective plate 500, each corresponding to a second connecting hole 111. After the second pressing block 300 is engaged on the first pressing block 200, the second connecting posts 510 are aligned with the second connecting holes 111 on the first connecting plate 110, and the second connecting posts 510 are inserted sequentially from top to bottom into the second connecting holes 111 of two adjacent first connecting plates 110. After the second connecting posts 510 are in place, the protective component is interference-fitted with the second connecting plate 120 of the frame 100, so that the protective component is engaged between two adjacent frames 100. Through the fit between the protective component and the frame 100, and the fit between the second connecting posts 510 and the second connecting holes 111, the protective component can conceal the internal structure of the frame 100 to maintain the aesthetic appearance of the building's exterior; and form a closed structure to prevent moisture and dust from penetrating into the interior of the frame 100. The protective components can be made of materials in the same color scheme as the building facade, with a matte or mirrored finish to blend seamlessly with the building's appearance, eliminating the jarring feel of industrial products and enhancing aesthetics. Furthermore, the protective components can be disassembled without tools, facilitating quick opening during maintenance.

[0047] It is understandable that a snap-fit ​​structure can be set on the second connecting post 510 so that the second connecting post 510 and the lower surface of the first connecting plate 110 can be automatically snapped and locked together. Similarly, no tools, screws, or glue are required throughout the process. Unlocking can be done simply by pulling the protective part upward by hand, so as to achieve quick disassembly and assembly.

[0048] In one embodiment, the photovoltaic module 400 includes a backsheet, solar cells, and encapsulation glass stacked sequentially. An adhesive film is provided between the solar cells and the backsheet, and between the solar cells and the encapsulation glass. A self-cleaning coating is applied to the encapsulation glass. Specifically, the adhesive film forms an adhesive layer between the solar cells and the backsheet, and also between the solar cells and the encapsulation glass, ensuring a tight bond between the backsheet, solar cells, and encapsulation glass while providing the photovoltaic module 400 with anti-permeability and waterproofing functions. Furthermore, fire-retardant and anti-leakage materials are applied around the photovoltaic module 400 to further enhance its fire resistance and waterproofing performance, preventing fire hazards and leakage.

[0049] A self-cleaning coating is applied to the encapsulation glass, which serves as the light-transmitting surface of the photovoltaic module 400. The self-cleaning coating reduces the adhesion of dust and dirt and utilizes rainwater for self-cleaning. The micro-nano structure of the self-cleaning coating guides rainwater to form a water film, improving rinsing efficiency and reducing manual cleaning by at least 2-3 times per year, thus lowering maintenance costs.

[0050] For example, a composite structure of micron-scale pyramid arrays and nanoscale needle-like hydrophobic structures can be constructed on the surface of encapsulation glass using the sol-gel method and nanoimprinting. The pyramid structure traps incident light into the glass through multiple refractions, thereby improving the light transmittance of the encapsulation glass. The nanoneedle structure makes the surface of the encapsulation glass superhydrophobic. Dust particles have a small contact area with the surface of the encapsulation glass and weak adhesion, making them easy to roll off under wind or light rain. At the same time, the surface of the encapsulation glass is coated with a photocatalytic nanofilm, which can decompose organic stains under sunlight. The superhydrophobic surface can also effectively prevent water film from freezing, and even if ice does form, the adhesion of the ice layer is greatly reduced, making it easy to fall off naturally.

[0051] In other possible implementations, a solid electrochromic film is embedded between the self-cleaning coating and the encapsulated glass. The system automatically adjusts the film's tinting depth based on data from indoor illuminance sensors, glare sensors, and instructions from the building energy management system. During midday's strong sunlight, the film is moderately tinted to reduce indoor glare and air conditioning load while ensuring power generation; during low light in the morning and evening, it maintains high transmittance to increase power generation. Furthermore, the encapsulated glass's tint can gradually change within a certain range, achieving a dynamic building facade effect.

[0052] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0053] The specific embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
