[0065] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0066] Building Integrated Photovoltaic, or BIPV, is a technology that integrates solar power generation (photovoltaic) products into buildings. BIPV is a photovoltaic system that, unlike traditional photovoltaic panels, integrates photovoltaic modules directly into the facade, roof, windows or other building components of a building. It can generate solar power and replace traditional building materials, with multiple advantages such as aesthetics and energy saving.

[0067] However, the BIPV system of the related art makes it difficult to replace photovoltaic modules when they are damaged. Photovoltaic modules are generally fixed by upper pressure pieces, and fixed wings are provided on both sides of the upper pressure pieces. The two fixed wings are used to fix different photovoltaic modules. If the original photovoltaic modules need to be removed, the upper pressure pieces need to be removed from the outside of the photovoltaic system first. For example, the photovoltaic system is set on the roof. In order to increase the number of photovoltaic modules and improve the photovoltaic capacity, there are very few operation and maintenance channels set on the photovoltaic system located on the roof. Generally, the operation and maintenance channels are only set at the ridge. If the damaged photovoltaic module is far away from the operation and maintenance channel, it is difficult to repair and replace it. Photovoltaic modules are fragile. If you go directly to the roof to replace the damaged photovoltaic module, it is easy to cause damage to other intact photovoltaic modules. Similarly, if the photovoltaic system is installed on the facade, windows or other building components of a building, it is also difficult to replace the damaged photovoltaic modules from the outside of the building.

[0068] like Figure 1 As shown, the photovoltaic assembly replacement method of the first embodiment of the present invention is used to replace the photovoltaic assembly 200 of the photovoltaic system, and the photovoltaic system presses the photovoltaic assembly 200 by the upper pressing member 100; the method comprises:

[0069] Step S100: removing the original photovoltaic assembly 200 from the installation position;

[0070] Step S200: cutting off the fixing wing 110 of the upper pressing member 100; wherein the fixing wing 110 is used to press the original photovoltaic module 200;

[0071] Step S300: Fix the new photovoltaic assembly 200 at the installation location.

[0072] The fixing wing 110 is used to press the original photovoltaic module 200. Due to the influence of the fixing wing 110, it is difficult to install the new photovoltaic module 200 to the installation position without removing the upper pressing piece 100. In the embodiment of the present invention, the fixing wing 110 is directly cut off from the upper pressing piece 100, and the new photovoltaic module 200 can be installed and fixed to the installation position without removing the upper pressing piece 100. The operator can operate on the inner side of the photovoltaic system without climbing to the roof or the outside of the building to replace the damaged photovoltaic module 200, thereby reducing the construction risk.

[0073] In step S100, the original photovoltaic assembly 200 is removed to free up an installation position for installing a new photovoltaic assembly 200. The original photovoltaic assembly 200 can be removed by directly smashing the original photovoltaic assembly 200 with a hammer or other tool.

[0074] See also Figures 4 to 8 In step S200, the fixing wing 110 is removed from the upper pressing member 100 so that the upper pressing member 100 no longer hinders the installation of the new photovoltaic module 200, so that the new photovoltaic module 200 can be installed smoothly. In step S200, the fixing wing 110 can be cut off by a cutting tool.

[0075] In step S300, the installation position is the original installation position of the original photovoltaic component 200; the original photovoltaic component 200 is removed, and the fixing wing 110 that presses the original photovoltaic component 200 is removed, and then the new photovoltaic component 200 is fixed at the installation position so that the new photovoltaic component 200 replaces the original photovoltaic component 200 and continues to work.

[0076] In general, if Fig.16 As shown, an upper pressing member 100 presses two adjacent photovoltaic modules 200. During the process of replacing a damaged photovoltaic module 200, if the entire upper pressing member 100 is directly removed, the other adjacent photovoltaic module 200 may become loose, which may cause the other adjacent photovoltaic module 200 to deviate from its original position; Figures 4 to 8 In the present application, the fixing wing 110 of the upper pressing member 100 is directly detached from the upper pressing member 100 , so that the upper pressing member 100 no longer restricts the installation of a new photovoltaic component 200 and does not affect other photovoltaic components 200 .

[0077] This article takes the photovoltaic system on the roof of a photovoltaic shed as an example. Generally, the height of the photovoltaic shed is 2.2 meters to 2.8 meters. Through climbing tools such as a stepladder or a lift, the lower part of the damaged photovoltaic module 200 on the roof can be reached from the inside of the photovoltaic shed; the damaged photovoltaic module 200 is smashed by a hammer or other tools to hollow out the installation position, and the fixed wing 110 is separated from the upper pressure piece 100 so that the new photovoltaic module 200 can be installed and fixed at the installation position.

[0078] In some embodiments, the upper pressing piece 100 is disposed on both opposite sides of the original photovoltaic assembly 200; the fixing wing 110 of the upper pressing piece 100 cut off comprises the following steps:

[0079] Step S210: cutting the fixing wing 110 of the upper pressing member 100 located on one side of the original photovoltaic assembly 200;

[0080] Step S220: cutting the fixing wing 110 of the upper pressing member 100 located on the other side of the original photovoltaic assembly 200.

[0081] The fixed wing 110 of the upper pressing piece 100 can be cut off by using a cutting tool such as an electric saw. The fixed wing 110 can be completely cut off, or a portion of the fixed wing 110 can be cut off, as long as the fixed wing 110 no longer hinders the installation of the new photovoltaic module 200. In the related art, the photovoltaic module 200 is generally pressed by the upper pressing piece 100 located on both sides thereof; in order to make the installation of the new photovoltaic module 200 smoother, in step S210, the fixed wing 110 of the upper pressing piece 100 located on one side of the original photovoltaic module 200 is first cut off, and then the fixed wing 110 of the upper pressing piece 100 located on the other side of the original photovoltaic module 200 is cut off through step S220, so as to reserve more space for the new photovoltaic module 200 to be installed.

[0082] See also Fig. 9It can be understood that the original photovoltaic component 200 is fixed by two upper pressing members 100, and the two upper pressing members 100 are respectively the first upper pressing member 120 and the second upper pressing member 130; along the direction from the first upper pressing member 120 to the second upper pressing member 130, the two photovoltaic components 200 adjacent to the original photovoltaic component 200 are set as the first photovoltaic component 210 and the second photovoltaic component 220; the first upper pressing member 120 has a first fixed wing and a second fixed wing on opposite sides, respectively, and the second upper pressing member 130 has a third fixed wing and a fourth fixed wing on opposite sides, wherein the first fixed wing presses one side of the first photovoltaic component 210, the second fixed wing presses one side of the original photovoltaic component 200, the third fixed wing presses the other side of the original photovoltaic component 200, and the fourth fixed wing presses one side of the second photovoltaic component 220. In the case that the original photovoltaic assembly 200 is damaged, after the original photovoltaic assembly 200 is removed, the second fixing wing is cut, and then the third fixing wing is cut, so that the new photovoltaic assembly 200 can be placed between the first upper pressing member 120 and the second upper pressing member 130 .

[0083] In some embodiments, fixing the new photovoltaic assembly 200 at the installation location comprises the following steps:

[0084] Step S310: transferring the new photovoltaic assembly 200 from the inner side of the photovoltaic system to the outer side of the photovoltaic system and placing it at the installation position;

[0085] Step S320: Fix the new photovoltaic component 200 through the connecting member 300.

[0086] Since it is inconvenient for operators to move to the outside of the photovoltaic system for operation, the new photovoltaic assembly 200 is transferred from the inside of the photovoltaic system to the outside of the photovoltaic system, so as to facilitate the placement of the new photovoltaic assembly 200 in the installation position; the connection between the new photovoltaic assembly 200 and other parts of the photovoltaic system can be improved through the connector 300, and the new photovoltaic assembly 200 can be prevented from falling. The new photovoltaic assembly 200 is fixed by the connector 300, and there is no need to disassemble and replace the original upper pressure piece 100, which reduces the workload of maintenance and reduces labor costs. In addition, compared with the original method of fixing with the upper pressure piece 100, the use of the connector 300 for fixing allows installation operations to be performed on the inside of the photovoltaic system, which improves the flexibility of operation.

[0087] If the photovoltaic system is installed on the top of the photovoltaic shed, the inner side of the photovoltaic system is under the roof, that is, indoors, and the outer side of the photovoltaic system is on the roof, that is, outdoors.

[0088] In some embodiments, before transferring the new photovoltaic assembly 200 from the inner side of the photovoltaic system to the outer side of the photovoltaic system and placing it at the installation position, the following steps are included:

[0089] The new photovoltaic module 200 is placed vertically.

[0090] After the original photovoltaic module 200 is removed, the installation position is hollowed out, and the new photovoltaic module 200 is placed vertically, so that the new photovoltaic module 200 can be transferred from the inside of the photovoltaic system to the outside through the hollowed-out installation position, and the operator can operate it while being located on the inside of the photovoltaic system. The new photovoltaic module 200 is placed vertically, that is, one of the sides of the photovoltaic module 200 faces upward, so that the photovoltaic module 200 can pass through the hollowed-out installation position; generally, the photovoltaic module 200 is a flat rectangle, and the photovoltaic module 200 has a short side and a long side. The short side of the photovoltaic module 200 can be placed vertically with the short side facing upward, and then the photovoltaic module 200 is passed through the hollowed-out installation position, so that the photovoltaic module 200 can be smoothly transferred from the inside of the photovoltaic system to the outside of the photovoltaic system.

[0091] See also Figures 4 to 8 In some embodiments, the photovoltaic system includes a fixing component 400, the photovoltaic assembly 200 has a support frame 230, and the connector 300 includes a first bracket 310 and a second bracket 320; the photovoltaic system and the new photovoltaic assembly 200 are connected by the connector 300, including the following steps:

[0092] Step S321: Connect the first bracket 310 to the support frame 230;

[0093] Step S322: Connect the second bracket 320 to the fixing component 400;

[0094] Step S323: Connect the first bracket 310 and the second bracket 320.

[0095] The first bracket 310 is connected to the support frame 230, the second bracket 320 is connected to the fixing component 400, and then the new photovoltaic module 200 is fixed on the photovoltaic system through the connection between the first bracket 310 and the second bracket 320; since the new photovoltaic module 200 is placed in the installation position from the outside of the photovoltaic system, the fixing component 400 supports the new photovoltaic module 200, so it is more difficult to connect the support frame 230 of the new photovoltaic module 200 with the connecting member 300 on the inside of the photovoltaic system; the connecting member 300 is divided into the first bracket 310 and the second bracket 320, the first bracket 310 is first connected to the support frame 230, and then the second bracket 320 is connected to the fixing component 400, and then the first bracket 310 and the second bracket 320 are connected, which can reduce the difficulty of fixing the new photovoltaic module 200.

[0096] See also Figures 4 to 8In some embodiments, the first bracket 310 includes a supporting portion 311 and a first extending portion 312 connected to each other, the supporting portion 311 and the first extending portion 312 are bent, the supporting portion 311 is close to the supporting frame 230, and the first extending portion 312 is used to connect the second bracket 320. By bending, the supporting portion 311 can be close to the supporting frame 230, thereby improving the reliability of the connection; the bending is conducive to the first extending portion 312 connecting the second bracket 320, so that the connection between the first bracket 310 and the second bracket 320 is more stable. In addition, the supporting portion 311 and the first extending portion 312 are bent, which can improve the strength and rigidity of the first bracket 310, so that the first bracket 310 has a greater bearing capacity and reduces the risk of deformation and breakage. Generally, the first bracket 310 is a bent iron sheet. The thickness of the first bracket 310 can be designed according to actual needs, and the embodiment of the present invention does not limit this.

[0097] See also Figures 7 and 8 In some embodiments, the first extension portion 312 includes a first section 312c, a second section 312e and a connecting section 312d, the first section 312c and the second section 312e are staggered in the extension direction of the first extension portion 312, and the connecting section 312d connects the first section 312c and the second section 312e. Since there is a height difference between the support frame 230 and the fixing component 400, the first section 312c and the second section 312e are staggered, which can shorten the distance between the first extension portion 312 and the second bracket 320, and is more conducive to the fixation of the first bracket 310 and the second bracket 320; the first section 312c and the second section 312e are staggered in the extension direction of the first extension portion 312, so that the first bracket 310 forms a shape similar to the letter "Y" in its extension direction, which can improve the supporting capacity of the first bracket 310 to a certain extent.

[0098] See also Figure 5 In some embodiments, the second bracket 320 includes a fixed portion 321 and a second extension portion 322 connected to each other, the fixed portion 321 and the second extension portion 322 are bent, the fixed portion 321 is close to the fixed component 400, and the second extension portion 322 is connected to the first extension portion 312. By bending, the fixed portion 321 can be close to the fixed component 400, thereby improving the reliability of the connection; the bending is conducive to the connection of the second extension portion 322 to the first extension portion 312, so that the connection between the first bracket 310 and the second bracket 320 is more stable. In addition, the fixed portion 321 and the second extension portion 322 are bent, which can improve the strength and rigidity of the second bracket 320, so that the second bracket 320 has a greater bearing capacity and reduces the risk of deformation and breakage. Generally, the second bracket 320 is a bent iron sheet. The thickness of the second bracket 320 can be designed according to actual needs, and the embodiment of the present invention does not limit this.

The first hole 312a and the second hole 322a are connected by the locking portion 330 to connect the first extension portion 312 and the second extension portion 322, so that the first bracket 310 and the second bracket 320 are connected; during installation, the first bracket 310 can be connected to the photovoltaic module 200, and then the second bracket 320 can be connected to the fixing component 400, and the first hole 312a and the second hole 322a are aligned, and then the first bracket 310 and the second bracket 320 are connected by the locking portion 330.

[0100] See also Fig.11 The locking portion 330 is a screw or a bolt. In order to improve the overall strength of the first extension portion 312, a connecting protrusion 312b can be provided on the first extension portion 312, and the first hole 312a is provided on the connecting protrusion 312b; when the first extension portion 312 and the supporting portion 311 are bent and the first extension portion 312 is close to the bottom of the new photovoltaic component 200, the first hole 312a is a blind hole to prevent the locking portion 330 from passing through the first hole 312a and causing the photovoltaic component 200 to be punctured.

[0101] See also Figure 8 and Fig.10 In some embodiments, the photovoltaic module 200 has a support frame 230 and a solar panel 240. The support frame 230 includes a clamping portion 231, a vertical arm 232 connected to the lower end of the clamping portion 231, and a base 233 connected to the lower end of the vertical arm 232. The clamping portion 231 is used to clamp the edge of the solar panel 240, and the base 233 is placed on the horizontal bar 500; the support portion 311 is in close contact with the vertical arm 232, and the height of the support portion 311 is less than or equal to the height of the vertical arm 232, so that the support portion 311 can be located between the clamping portion 231 and the base 233, and is set in close contact with the vertical arm 232, thereby improving the firmness of the connection between the first bracket 310 and the support frame 230.

[0102] The clamping part 231 clamps and fixes the battery panel 240. The clamping part 231 is provided with an upper clamping arm, a lower clamping arm and a clamping groove 234 between the upper clamping arm and the lower clamping arm.

The base 233 is arranged horizontally, which is integrally connected to the bottom of the vertical arm 232 and extends horizontally toward the inside. Its extension direction is the same as the extension direction of the upper clamping arm and the lower clamping arm, but its extension length exceeds the extension length of the upper clamping arm and the lower clamping arm.

[0103] In some embodiments, the locking portion 330 and the supporting portion 311 are arranged side by side, so that the locking portion 330 can pass through the first hole 312a and the second hole 322a along the length direction of the supporting portion 311, thereby reducing the difficulty of operation.

[0104] In some embodiments, the fixing component 400 is a water channel, and a horizontal bar 500 is mounted on the water channel; the first bracket 310 is connected to the support frame 230, including the following steps:

[0105] Step S322a: placing the first bracket 310 on the horizontal bar 500;

[0106] Step S322b: Fix the first bracket 310 on the support frame 230 by fixing screws.

[0107] By placing the first bracket 310 on the horizontal bar 500 , the horizontal bar 500 supports the first bracket 310 , making it easier to connect the first bracket 310 to the support frame 230 of the new photovoltaic assembly 200 .

[0108] In some embodiments, the fixing component 400 is a water channel, and a horizontal bar 500 is mounted on the water channel; the first bracket 310 is connected to the support frame 230, including the following steps:

[0109] Step S321c: fix the first bracket 310 on the support frame 230 by fixing screws; wherein, along the extension direction of the water guide groove, the first bracket 310 and the horizontal bar 500 are staggered.

[0110] The first bracket 310 and the horizontal bar 500 are staggered, and the first bracket 310 does not need to be installed according to the position of the horizontal bar 500. The fixed position of the first bracket 310 can be set as needed, which is more flexible in operation. In other words, in the extension direction of the water guide groove, the first bracket 310 can be fixed to any position of the new photovoltaic module 200 that is staggered with the horizontal bar 500, reducing the interference of the horizontal bar 500 on the first bracket 310.

[0111] In some embodiments, the fixing component 400 is a water channel, a horizontal bar 500 is mounted on the water channel, and the first bracket 310 includes a supporting portion 311 and a first extending portion 312 connected to each other; the first bracket 310 is connected to the supporting frame 230, including the following steps:

[0112] Step S321d: placing the first bracket 310 below the new photovoltaic assembly 200, so that the support portion 311 supports the new photovoltaic assembly 200, and the first extension portion 312 is in close contact with the bottom of the new photovoltaic assembly 200;

[0113] Step S321e: Fix the support part 311 on the support frame 230 by fixing screws.

[0114] The support portion 311 can fix the new photovoltaic component 200 , and the first extension portion 312 can support the new photovoltaic component 200 to disperse the pressure of the new photovoltaic component 200 on the connector 300 , improve stability, and more securely fix the new photovoltaic component 200 .

[0115] The second aspect of the present invention provides a photovoltaic system. Based on the photovoltaic module replacement method of the first aspect of the present invention, the photovoltaic system includes a fixing component 400, a photovoltaic module 200 and a connecting member 300; the photovoltaic module 200 has a support frame 230; the connecting member 300 is connected to the fixing component 400 and the support frame 230 of one of the photovoltaic modules 200.

[0116] The new photovoltaic assembly 200 is connected and fixed by the connecting member 300 , and the photovoltaic assembly 200 can be replaced on the inner side of the photovoltaic system without using the upper pressing member 100 , thereby improving the installation performance and flexibility of the operation.

[0117] In some embodiments, the photovoltaic system further includes an upper pressure piece 100 , one side of which has a fixing wing 110 , and the other side forms an escape space, wherein the escape space is used to escape the photovoltaic component 200 when replacing a new photovoltaic component 200 .

[0118] The upper pressing piece 100 is used to press the original photovoltaic module 200. When the original photovoltaic module 200 is damaged, a clearance space is formed on one side of the upper pressing piece 100 by cutting or other means to facilitate the removal of the damaged photovoltaic module 200. At the same time, the upper pressing piece 100 can be prevented from hindering the installation of the new photovoltaic module 200.
