[0040] The existing photovoltaic tile system mounted up and down and the vertically installed exterior photovoltaic panel system applied to the sloping roof of the building do not take into account the connection relationship with the existing building maintenance structure; do not consider the adaptability of different enclosure structure parts such as facades and roofs in the renovation of existing buildings, and the structural problems of key intersections such as eaves, door and window openings; and cannot meet the requirements for improving the comprehensive performance of the building enclosure structure, including the aesthetic and uniformity of the building appearance, the overall structural problems between the building and the main enclosure structure, the optimization of solar energy utilization efficiency, and the wind and rain protection of the building surface.

[0041] The present application provides a photovoltaic building integrated enclosure structure, which is applied to a building, wherein the building includes an exterior wall; Figures 1 to 5As shown, the photovoltaic building integrated enclosure structure includes a first keel 300 and a plurality of first photovoltaic modules 400, the first keel 300 is used to be connected to the exterior wall 100; the plurality of first photovoltaic modules 400 are all connected to the first keel 300, and are located on the side of the first keel 300 away from the exterior wall 100, the end of the first photovoltaic module 400 away from the ground is the top end, and the end of the first photovoltaic module 400 close to the ground is the tail end, and the plurality of first photovoltaic modules 400 are all inclined relative to the first keel 300, and in two adjacent layers of the first photovoltaic modules 400, the top end of the first photovoltaic module 400 located in the lower layer extends to between the tail end of the first photovoltaic module 400 in the upper layer and the first keel 300.

[0042] The above photovoltaic building integrated enclosure structure connects the first keel 300 to the outer wall 100 of the house, and then connects the plurality of first photovoltaic modules 400 to the first keel 300, so that the plurality of first photovoltaic modules 400 are installed on the outer wall 100. Moreover, the plurality of first photovoltaic modules 400 are all inclined relative to the first keel 300, and in two adjacent layers of first photovoltaic modules 400, the top end of the first photovoltaic module 400 located in the next layer extends between the tail end of the first photovoltaic module 400 in the previous layer and the first keel 300, that is, the plurality of first photovoltaic modules 400 are fixed on the outer wall 100 by using a shingle structure. Compared with the existing photovoltaic modules only laid on the roof 200, the photovoltaic building integrated enclosure structure of the present application, through the first keel 300 and the first photovoltaic module 400, adds the first photovoltaic module 400 to the outer wall 100 of the house, which not only meets the requirements for improving the comprehensive performance of the building enclosure structure and protects the building surface, but also increases the amount of solar radiation received by the photovoltaic surface by adjusting the inclination angle of the first photovoltaic module 400 and increasing the total area of ​​photovoltaic modules laid on the building (such as a house), thereby providing more clean energy for the house.

[0043] It should be noted that the exterior wall 100 of a building refers to a component that surrounds a building and forms a boundary between indoor and outdoor areas. The roof 200 of a building refers to a roof (top surface).

[0044] It should be noted that the photovoltaic building integrated enclosure structure of the present application is applied to a building, and the building may be a building with high thermal performance.

[0045] Furthermore, if Figure 1 and Figure 5 As shown, a plurality of first photovoltaic modules 400 are arranged on the exterior wall 100 through the first keel 300, and the plurality of first photovoltaic modules 400 are arranged along a first direction, wherein the first direction is the width direction of the building, and the first direction is perpendicular to the length direction of the first keel 300. It can be understood that the plurality of first photovoltaic modules 400 arranged along the first direction is a layer of first photovoltaic modules 400.

[0046] Specifically, multiple layers of first photovoltaic components 400 are provided, and the multiple layers of first photovoltaic components 400 are arranged along the length direction of the first keel 300 or along the height direction of the external wall 100 .

[0047] More specifically, the multi-layer first photovoltaic modules 400 are overlapped in staggered layers. The multi-layer first photovoltaic modules 400 are overlapped in staggered layers, which not only prevents rainwater and dust from entering the interior of the enclosure structure and improves the waterproof performance of the house, but also the overlapped staggered layers of the first photovoltaic modules 400 increase the fault tolerance of the installation and construction and improve the visual aesthetic effect.

[0048] Specifically, Figures 1 to 5 As shown, the angle between the first photovoltaic assembly 400 and the external wall 100 is an acute angle. In two adjacent layers of first photovoltaic assemblies 400, the top of the first photovoltaic assembly 400 located in the next layer extends between the tail end of the first photovoltaic assembly 400 in the previous layer and the first keel 300, and the first photovoltaic assembly 400 and the external wall 100 are arranged at an acute angle, that is, the angle between the length direction of the first photovoltaic assembly 400 and the length direction of the first keel 300 is an acute angle, that is, in two adjacent layers of first photovoltaic assemblies 400, the top of the first photovoltaic assembly 400 in the next layer is located between the top of the first photovoltaic assembly 400 in the previous layer and the first keel 300, that is, the size between the top of the first photovoltaic assembly 400 and the external wall 100 is smaller than the size between the tail end of the first photovoltaic assembly 400 and the external wall 100, so that dust and rainwater on the first photovoltaic assembly 400 can fall freely to the ground under the action of gravity.

[0049] More specifically, the angle between the first photovoltaic assembly 400 and the exterior wall 100 is greater than 0° and less than 90°, which is determined according to the sunshine conditions of the site where the house is located.

[0050] It is understandable that, regarding the inclination angle of the photovoltaic assembly 400, each latitude has an optimal inclination angle, but the first photovoltaic assembly 400 is usually arranged vertically, and the facade is at a certain angle to increase the amount of solar radiation received by the photovoltaic surface, thereby increasing the power generation. The angle of the first photovoltaic assembly 400 can be any angle.

[0051] In some embodiments, Figures 1 to 5 As shown, the inclination angles of the plurality of first photovoltaic modules 400 are the same. The inclination angles of the plurality of first photovoltaic modules 400 arranged on the exterior wall 100 are the same, thereby improving the appearance of the house.

[0052] In other embodiments, the inclination angles of the multiple first photovoltaic components 400 may be different, as long as the angles between the multiple first photovoltaic components 400 and the exterior wall 100 are acute, the amount of solar radiation received by the surface of the first photovoltaic components 400 can be increased, so that dust and rainwater can fall freely to the ground under the action of gravity.

[0053] In some embodiments, Figures 2 to 4 As shown, the first photovoltaic module 400 includes a front glass 410, a first transparent PVB film 420, a cell 430, a second transparent PVB film 440, a black PVB film 450 and a back film 460 connected in sequence. The front glass 410 is arranged on the side away from the first keel 300, and the cell 430 of the first photovoltaic module 400 is located in its own unshielded area, wherein the unshielded area is the area that is not blocked by the tail end of the first photovoltaic module 400 of the upper layer. The present application adjusts the overall color of the first photovoltaic module 400 by setting the first transparent PVB film 420 and the second transparent PVB film 440 to clamp the cell 430, and by setting the black PVB film 450. The present application adopts laminated glass photovoltaic, which is suitable for photovoltaic chips of different materials and technical paths. By matching the appearance performance of the photovoltaic chip and the laminated glass, such as color and reflectivity, the cell chip and the grid line are hidden in appearance. Moreover, the cell 430 of the first photovoltaic module 400 is located in the middle and lower part (unshielded area) of the sandwich space formed by the first transparent PVB film 420 and the second transparent PVB film 440, that is, located on the side away from its own front end. The cell 430 is arranged in the lower part of the module with less shielding, reducing the shielding of the first photovoltaic module 400 of the upper layer, and improving the synthesis efficiency of the first photovoltaic module 400.

[0054] Specifically, Figure 3 and Figure 4 As shown, the cell sheets 430 of the first photovoltaic assembly 400 of the next layer are spaced apart from the shielding area 480 of the first photovoltaic assembly of the previous layer.

[0055] In some embodiments, Figures 1 to 4 As shown, a plurality of first photovoltaic modules 400 are arranged to form a first space 470, and the first space 470 is used to expose the doors and windows of the house; the photovoltaic building integrated enclosure structure also includes door and window covers, which are installed in the exposed edge areas of the first photovoltaic modules that are arranged to form the first space. When a plurality of first photovoltaic modules 400 are laid on the exterior wall 100, the plurality of first photovoltaic modules 400 can be arranged to form a first space 470, which is convenient for exposing the doors and windows of the house. The edges of the first photovoltaic modules 400 at the door and window openings are closed by installing the door and window covers in the exposed edge areas of the first photovoltaic modules that are arranged to form the first space.

[0056] In some embodiments, Figures 1 to 3As shown, the photovoltaic building integrated enclosure structure also includes a first thermal insulation member 800, a first connecting member 810 and a first insulation layer 700. The first keel 300, the first insulation layer 700, the first thermal insulation member 800 and the main load-bearing components of the building are arranged in sequence, and the first thermal insulation member 800 is attached to the first insulation layer 700 and the main load-bearing components of the building. The first connecting member 810 passes through the first keel 700 and the first insulation layer 800 in sequence and is connected to the main load-bearing components. By setting the first insulation layer 700, the first insulation layer 700 is sandwiched between the first keel 300 and the main load-bearing components of the building, thereby insulating the building. By setting the connecting member 810, the connecting member 810 passes through the first keel 300, the first insulation layer 700 in sequence and is connected to the main load-bearing components of the building, thereby connecting the first keel 300, the first insulation layer 700, the first thermal insulation member 800 and the main load-bearing components. A first thermal insulation component 800 is provided between the first thermal insulation layer 700 and the main load-bearing components of the building. The first thermal insulation component 800 reduces the structural layers penetrating the fixing points of the first thermal insulation layer 700, realizes the cold bridge structure, and completes the connection processing between the first photovoltaic component 400 and the high-performance enclosure structure on the inner side of the epidermis. The first photovoltaic component 400 is fixed as a whole by the first keel 300, and an anti-fall chain is provided; the first keel 300 is fixed through the first thermal insulation layer 700 and the structural layer of the outer wall 100 through a small number of point-like connection nodes, and a high-strength spacer 800 is provided to realize the cold bridge structure.

[0057] Specifically, the first thermal insulation member 800 is a thermal insulation gasket.

[0058] Specifically, the main load-bearing components of the building include I-shaped steel structural beams. In other embodiments, the main load-bearing components of the building can also use other structural members.

[0059] In some embodiments, Figure 1 and Figure 5As shown, the building also includes a roof 200 connected to the exterior wall 100; the photovoltaic building integrated enclosure structure also includes a second keel 500 and a plurality of second photovoltaic modules 600, the plurality of second photovoltaic modules 600 are all connected to the roof 200 through the second keel 500, the end of the second photovoltaic module 600 away from the exterior wall 100 is the top end, the end of the second photovoltaic module 600 close to the exterior wall 100 is the tail end, the plurality of second photovoltaic modules 600 are all inclined relative to the second keel 500, and the angle between the length direction of the second photovoltaic module 600 and the length direction of the second keel 500 is an acute angle, and in two adjacent layers of the second photovoltaic modules 600, the top end of the second photovoltaic module 600 located in the next layer extends into the tail end of the second photovoltaic module 600 in the previous layer and between the second keel 500. By arranging a plurality of second photovoltaic modules 600 on the roof 200 of the house, the energy provided by the photovoltaic building integrated enclosure structure is further enhanced. Moreover, the length directions of the multiple second photovoltaic components 600 are at acute angles to the length direction of the second keel 500. In two adjacent layers of second photovoltaic components 600, the top end of the second photovoltaic component 600 in the next layer extends to between the tail end of the second photovoltaic component 600 in the previous layer and the second keel 500, thereby facilitating the discharge of dust and rainwater on the second photovoltaic components 600.

[0060] Furthermore, if Figure 1 and Figure 5 As shown, a plurality of second photovoltaic modules 600 are arranged on the exterior wall 100 through the second keel 500, and the plurality of second photovoltaic modules 600 are arranged along the second direction, wherein the second direction is the width direction of the building, and the second direction is perpendicular to the length direction of the second keel 500. It can be understood that the plurality of second photovoltaic modules 600 arranged along the second direction is a layer of second photovoltaic modules 600.

[0061] Specifically, multiple layers of second photovoltaic components 600 are provided, and the multiple layers of second photovoltaic components 600 are arranged along the length direction of the second keel 500 .

[0062] More specifically, the multi-layer second photovoltaic modules 600 are overlapped in staggered layers. The multi-layer second photovoltaic modules 600 are overlapped in staggered layers, which not only prevents rainwater and dust from entering the interior of the enclosure structure and improves the waterproof performance of the house, but also the overlapped staggered layers of the second photovoltaic modules 600 increase the fault tolerance of the installation and construction and improve the visual aesthetic effect.

[0063] Preferably, by adjusting the inclination angles of the first photovoltaic assembly 400 and the second photovoltaic assembly 600 , the construction logic and finishing effect of the roof 200 and the exterior wall 100 are made consistent.

[0064] Specifically, in this embodiment, the structure of the first photovoltaic assembly 400 is the same as the structure of the second photovoltaic assembly 600 .

[0065] In other embodiments, the structures of the first photovoltaic assembly 400 and the second photovoltaic assembly 600 may be different, as long as the function of providing energy can be achieved.

[0066] In some embodiments, Figure 1 and Figure 5 As shown, a second space 610 is provided between two adjacent layers of the second photovoltaic assembly 600 in the multi-layer second photovoltaic assembly 600 to leave a drainage ditch construction area. A second space 610 is provided between two adjacent layers of the second photovoltaic assembly 600 in the multi-layer second photovoltaic assembly 600, and rainwater can flow along the length direction of the second photovoltaic assembly 600 to the drainage ditch formed by the second space 610, which is convenient for drainage.

[0067] Specifically, Figure 1 and Figure 5 As shown, a second space 610 (drainage ditch) is provided between the second photovoltaic module 600 of the first layer and the second photovoltaic module 600 of the second layer, that is, in the second layer area, to organize the rainwater of the roof 200, and an aluminum alloy profile is used for edge sealing. Thus, a simple and unified appearance effect is achieved at the junction of the roof 200 and the facade.

[0068] It should be noted that the eaves refer to the typical horizontal parts with protruding edges at the top of the building composition, and are often mistaken for "edges". Generally speaking, the eaves of the roof 200 refers to the upper edge of the eaves at the outermost edge of the large roof 200, that is, the "upper edge".

[0069] In some embodiments, Figure 1 and Figure 5 As shown, the top of the topmost first photovoltaic assembly 400 in the multi-layer first photovoltaic assembly 400 is arranged below the second photovoltaic assembly 600 in the multi-layer second photovoltaic assembly 600 which is closest to the outer wall 100, so that the eaves meet. That is, the top of the topmost first photovoltaic assembly 400 is arranged below the second photovoltaic assembly 600 in the outermost layer, so that dust and rainwater on the plurality of second photovoltaic assemblies 600 can flow out along the tail ends thereof, preventing dust and rainwater from flowing onto the first photovoltaic assembly 400.

[0070] In some embodiments, Figure 1 and Figure 5 As shown, the photovoltaic building integrated enclosure structure also includes a second thermal insulation member, a second connecting member and a second thermal insulation layer 900. The second keel 500, the second thermal insulation layer 900, the second thermal insulation member and the main load-bearing components of the building are arranged in sequence, and the second thermal insulation member is attached to the second thermal insulation layer 900 and the main load-bearing components. The second connecting member passes through the second keel 500 and the second thermal insulation layer 900 in sequence and is connected to the main load-bearing components.

[0071] In summary, this application has the following beneficial effects:

[0072] The present invention is aimed at the integrated construction system of photovoltaic building integrated enclosure structure, drawing on the construction logic of slotted curtain wall, and through the three levels of photovoltaic module construction, key connection part construction, and connection with existing building enclosure structure, to achieve the integrated construction system of photovoltaic building integrated enclosure structure that is universal to different parts of the building enclosure structure renovation, while meeting the optimization of thermal performance, appearance effect, solar energy utilization efficiency, wind and rain protection, and structural integrity. (such as Figure 1 shown)

[0073] 1. Structure of the first photovoltaic assembly 400 / the second photovoltaic assembly 600:

[0074] 1) (Appearance adjustment of photovoltaic module packaging): Based on the existing battery chip technology, laminated glass photovoltaic is used to adapt to photovoltaic chips of different materials and technical paths. By matching the appearance performance of photovoltaic chips and laminated glass such as color and reflectivity, the battery chips and grid lines are hidden in appearance. This method is also applicable to other battery chip technical paths.

[0075] 2) Considering the solar energy utilization efficiency, the installation mode of staggered mounting of the components up and down: The photovoltaic skin structure adopts the installation mode of staggered mounting up and down to achieve wind and rain protection for the main enclosure structure of the building with high thermal performance. The inclination angle of the component is adjusted by the connector 810, and the logic and completion effect of the roof 200 and the facade structure are consistent. The battery chip is arranged at the lower part of the component with less shading, and a single chip is connected in series horizontally to reduce the adverse effect of the upper unit shading on the production capacity. (such as Figure 3 shown)

[0076] 2. Structure of key connection parts: Key connection parts include the eaves of the photovoltaic skin and the slit-type structural treatment at the upper and lower junctions of doors and windows.

[0077] 1) Eaves: A drainage ditch is set at the second modular unit from the eaves to organize the 200 rainwater on the roof. The photovoltaic module of the first modular unit of the eaves of the roof is overhanging and overlapped on the photovoltaic module of the first modular unit on the facade, and the edge is sealed with aluminum alloy profiles. Thus, the appearance effect is simple and unified at the intersection of the roof 200 and the facade.

[0078] 2) The upper and lower junctions of door and window frames: The doors and windows are edged with short overhanging steel door and window frames, and the first modular unit photovoltaic modules and door and window frames are opened. This achieves a simple and unified appearance at the junction of the opening and the photovoltaic surface.

[0079] 3. Connection with existing building envelope:

[0080] By reducing the structural layers of the fixed points penetrating the insulation layer and the cold-break bridge structure, the photovoltaic skin and the high-performance enclosure structure inside the skin are connected: the photovoltaic skin is fixed as a whole by the steel keel, and an anti-fall chain is set; the steel keel is fixed through a small number of point-shaped connection nodes through the insulation layer and the structural layer, and a high-strength spacer 800 is set to achieve the cold-break bridge structure. (such as Figure 5 shown)

[0081] This application achieves the performance improvement of the integrated photovoltaic building enclosure structure with universality in the energy-saving transformation of the existing building enclosure structure through three levels: photovoltaic component structure, key connection part structure, and connection with the existing building enclosure structure. Through the installation mode of staggered hanging of photovoltaic components up and down, laminated glass photovoltaic packaging measures with adjustable materials, flexibly adjustable component geometric parameters, and structural treatment of key connection parts such as photovoltaic skin and eaves, door and window openings, the adaptability of the present invention to different enclosure structure parts is achieved. The staggered hanging installation mode realizes the wind and rain protection of the photovoltaic skin for the inner layer of the main enclosure structure; the laminated glass photovoltaic packaging measures and the staggered hanging structural logic form a structural method that can be flexibly designed to meet the effect requirements, and at the same time, the production capacity performance can be optimized under the structural logic according to the building requirements; the overall structural treatment of the photovoltaic skin and the main enclosure structure is completed by reducing the structural level of the fixed points penetrating the insulation layer. Therefore, the present invention can achieve comprehensive enclosure structure performance optimization.
