Technical Field

[0002] Green and renewable energy has transformed from a supplement to incremental energy and electricity consumption to the main driver of incremental energy and electricity consumption. Photovoltaic power generation, as a backbone of renewable energy development, accounts for a significant portion of building energy consumption. Therefore, developing photovoltaic wall systems is an important way to achieve this goal.

[0003] Current photovoltaic wall (curtain wall) modules typically combine solar cells with ordinary architectural glass and glass back panels to create a power-generating wall material. This adds power generation functionality while maintaining the original wall's maintenance attributes, safety, and aesthetics.

In addition, this design also helps to increase the proportion of PV panels on the building wall, making the arrangement of PV panels on the wall more reasonable, in order to achieve the best power generation effect.

[0053] In related technologies, photovoltaic wall-mounted modules need to be designed according to different building heights and column spans. This results in multiple photovoltaic panels (modules) of different sizes within the same building, with the panel sizes becoming increasingly complex across different buildings. This leads to difficulties in photovoltaic panel production and high production costs. Furthermore, the arrangement of these panels results in low utilization of wall space, thus failing to achieve optimal power generation performance.

[0054] Based on the aforementioned problems, this application provides a photovoltaic array structure. By arranging multiple sets of this photovoltaic array structure on the facade of a building, a modular design of the building facade is achieved, and the number of non-standard photovoltaic modules (photovoltaic panels) can be reduced, thereby reducing production difficulty and production costs.

[0055] See Figures 1-3 As shown, Figure 1 This is a schematic diagram of the layout of a photovoltaic array system on a roof according to some embodiments of this application. Figure 2 for Figure 1 Cross-sectional view of HH. Figure 3 for Figure 1 A cross-sectional view of section II. One embodiment of this application provides a photovoltaic array structure that may include at least one photovoltaic unit 10.

[0056] The photovoltaic unit 10 includes panel components 110 and panel modules 120 arranged sequentially along a first direction. The panel component 110 includes a photovoltaic panel 101 or a first matching panel 102. The panel module 120 includes at least one photovoltaic panel 101 and / or at least one auxiliary component 103 arranged sequentially along the first direction. The photovoltaic unit 10 includes at least one photovoltaic panel 101. In the first direction, the size of the panel component 110 is A, and the size of the panel module 120 is B. In the second direction intersecting the first direction, the size of the panel component 110 and the size of the panel module 120 are both L, B≤n﹒ A, where n is the sum of the number of all photovoltaic panels 101 and the number of all auxiliary components 103 in the panel module 120.

[0057] It is understood that the photovoltaic array structure provided in this example is used for buildings, such as building walls, as a curtain wall. In practical applications, multiple photovoltaic array structures can be arrayed to cover the entire building wall. To overcome the situation in related technologies where multiple photovoltaic modules (i.e., photovoltaic panels 101) of different sizes exist in the same building, this example adopts a modular design for the photovoltaic array structure. Specifically, this can be achieved by establishing a relationship between the dimensions of the building (e.g., the column span spacing) and the dimensions of the photovoltaic panels 101 (e.g., providing formulaic guidance) to form the standard dimensions of the photovoltaic panels 101.

[0058] Specifically, the photovoltaic (PV) array structure can be divided into PV units 10, and the arrangement and quantity of panel components 110 and panel modules 120 in each PV unit 10 are different to flexibly meet the needs of building walls for lighting, ventilation, etc. This example uses a PV array structure including one PV unit 10 as an example. The direction along the height of the building is defined as the second direction. In one example, the second direction is perpendicular to the first direction. That is, the first direction is along the width of the building. For ease of description, when dividing the PV unit 10, panel component 110 is used as the standard component. That is, the dimensions of panel component 110 are the standard dimensions of the above design, with a width of A and a height of L. Of course, panel component 110 can be a PV panel 101 or a first matching panel 102. The first matching panel 102 is mainly used to meet the needs of wall lighting, ventilation, etc.

[0059] A panel module 120 is arranged on one side of the panel component 110 along the first direction. The panel module 120 can also be further divided, for example, into at least one photovoltaic panel 101, or into at least one auxiliary component 103, or into at least one photovoltaic panel 101 and at least one auxiliary component 103. However, it should be noted that in order to ensure the proportion of the photovoltaic panel 101 on the wall, each photovoltaic unit 10 must ensure that there is at least one photovoltaic panel 101. In other words, when the panel component 110 is a photovoltaic panel 101, the panel module 120 may include a photovoltaic panel 101, an auxiliary component 103, or a photovoltaic panel 101 + an auxiliary component 103; while when the panel component 110 is the first matching plate 102, the panel module 120 may include a photovoltaic panel 101, a photovoltaic panel 101 + an auxiliary component 103.

[0060] This example divides the photovoltaic (PV) array structure into PV units 10, PV units 10 into panel components 110 and panel modules 120, and panel modules 120 into PV panels 101 and / or auxiliary components 103. This allows the standard-sized PV panel 101 to have a relatively small size. This design improves the reliability of the PV panel 101 itself, facilitates the design of the PV array structure, reduces costs, and ensures the reliability of the PV array structure. Furthermore, it improves the wind pressure resistance of the PV array structure. Under the condition of achieving the same wind pressure resistance, the smaller PV panel 101 requires less glass thickness, thus reducing the cost of the PV array structure.

[0061] To further improve the space utilization of the wall surface where the photovoltaic panels 101 are installed and achieve optimal power generation, this example design establishes the following relationship between the size B of the panel module 120 and the size A of the panel component 110: B ≤ n ﹒ A, where n is the sum of the number of all photovoltaic panels 101 and all auxiliary components 103 in the panel module 120. Specifically, assuming a photovoltaic unit 10 is designed and arranged in a column span of a building, it is necessary to involve as many photovoltaic panels 101 as possible in the panel module 120 to increase the wall surface area occupied by the photovoltaic panels 101.

[0062] For example, a panel 110 and (n-1) photovoltaic panels 101 are arranged in a column span, but there is a space with a width less than A. To ensure the integrity and aesthetics of the wall, an auxiliary component 103 can be designed and arranged in this space. The width dimension of the auxiliary component 103 is less than A, i.e., B < n·A. In other words, when standard-sized photovoltaic panels 101 are arranged sequentially along the first direction with the panel 110 as the reference, the auxiliary component 103 can be used to fill the space with a width less than A. Furthermore, when B = n·A, it is precisely the case where multiple standard-sized panels (panel 110 and photovoltaic panels 101) can be completely arranged in the column span. This design can significantly increase the proportion of standard-sized photovoltaic panels 101, and this arrangement is conducive to forming a production line for photovoltaic panels 101, improving production efficiency and reducing production costs.

[0063] It should be noted that the photovoltaic panel 101 described above may include a laminate, which includes glass, encapsulation material, solar cells, and a backsheet. The encapsulation material may be an EVA (polyethylene-vinyl acetate resin) film, and the backsheet may be glass. The photovoltaic panel 101 described above can be fixed to the exterior wall of a building using mounting components such as main and secondary joists, subframes, and cover plates. Standard-sized photovoltaic panels 101 also contribute to improved stability of the mounting components and reduce the difficulty of installation, inspection, and maintenance.

[0064] In this application, the photovoltaic (PV) array structure is divided into PV units 10, PV units 10 are further divided into panel components 110 and panel modules 120, and panel modules 120 are further divided into PV panels 101 and / or auxiliary components 103. The dimensions of the PV panels 101 are correlated with the dimensions of the building in the first direction (e.g., column span spacing), thus providing a formulaic guide for the standard size design of the PV panels 101. On the one hand, this reduces communication costs between architects and PV designers, shortens design time and costs; on the other hand, it allows the overall dimensions of the PV array structure to match the dimensions of the building, facilitating modular design of the building's curtain wall, promoting the uniformity of PV panel 101 dimensions, and thus facilitating the assembly line production of PV panels 101, improving production efficiency, shortening delivery cycles, and reducing production costs. Furthermore, this design also helps to increase the proportion of PV panels 101 on the building wall, making the arrangement of PV panels 101 on the wall more rational, thereby achieving optimal power generation.

[0065] In addition, in the above example, the dimensions of panel component 110 and panel module 120 along the second direction (height direction) are both L. There are cases where panel component 110 and panel module 120 are misaligned along the second direction. Of course, this also includes cases where the two ends of panel component 110 are aligned with the two ends of panel module 120, which is not limited here.

[0066] Below, we will combine the appendix Figure 1 -Appendix Figure 12 The specific arrangement structure of the photovoltaic array provided in the embodiments of this application will be described.

[0067] like Figure 1 As shown, in some embodiments, along the second direction, the two ends of the panel module 120 are flush with the two ends of the panel member 110; wherein, A+B<D, L<H, D is the column span of the building, and H is the floor height of the building.

[0068] Specifically, along the height of the building, the top / bottom of panel module 120 is flush with the top / bottom of panel piece 110. This arrangement facilitates the arraying of multiple photovoltaic structures on the wall. To facilitate the design of the standard dimensions of photovoltaic panel 101, the spacing of multiple column spans in the building can be collected to ensure that photovoltaic unit 10 satisfies A+B<D, L<H. Of course, here, the dimensions A of panel piece 110 and B of panel module 120 can be understood as being infinitely close to the column span spacing D, and the dimensions L of panel piece 110 and panel module 120 are infinitely close to the building's floor height.

[0069] To further understand the specific arrangement of photovoltaic panels 101 in the photovoltaic array structure, the following different embodiments can be used for understanding.

[0070] like Figure 1 As shown, in some embodiments, the photovoltaic array structure includes a first photovoltaic unit, which includes a panel 110 and a panel module 120 arranged sequentially along a first direction. The panel module 120 includes an auxiliary component 103; wherein the size B of the panel module 120 is smaller than A.

[0071] Specifically, the photovoltaic array structure may include a panel 110 and an auxiliary component 103. The size of the auxiliary component 103 is B, which is smaller than A. For example, the panel 110 is a photovoltaic panel 101, and the auxiliary component 103 is a second matching panel. The second matching panel may be a light-transmitting glass panel (for lighting), an adjustable glass panel (for ventilation), or other decorative panels with decorative effects; there are no restrictions here.

[0072] Based on the above photovoltaic array structure, combined with Figure 7-9 As shown, Figure 7 This is a schematic diagram of the arrangement of photovoltaic array structures provided in some embodiments of this application in a building. Figure 3 . Figure 8 for Figure 7 A cross-sectional view along the MM direction. Figure 9 for Figure 7A cross-sectional view along the NN direction. In some embodiments, the photovoltaic arrangement structure further includes a second photovoltaic unit, which is arranged sequentially with the first photovoltaic unit along a second direction; the second photovoltaic unit includes a panel member 110 and a panel module 120 arranged sequentially along a first direction, and the panel module 120 includes an auxiliary member 103; wherein, the auxiliary member 103 includes a plurality of sub-auxiliary members 1031 arranged along the second direction.

[0073] Specifically, the first photovoltaic unit and the second photovoltaic unit are arranged sequentially along the height of the building. To facilitate array arrangement on the building wall, the first photovoltaic unit and the second photovoltaic unit have the same dimensions in the first direction. The arrangement and quantity of the panel component 110, photovoltaic panel 101 and auxiliary component 103 in the second photovoltaic unit correspond to those of the first photovoltaic unit. For example, the second photovoltaic unit includes one panel component 110 and one auxiliary component 103. The difference is that the auxiliary component 103 in the second photovoltaic unit includes multiple sub-auxiliary components 1031. In one example, the sum of the dimensions of the multiple sub-auxiliary components 1031 along the second direction is equal to L. For example, panel 110 is photovoltaic panel 101, and auxiliary component 103 includes two sub-auxiliary components 1031. The length of the first sub-auxiliary component 1031 is L1, and the length of the second sub-auxiliary component 1031 is L2. L1 and L2 can be the same or different, but their sum must be equal to L. The two sub-auxiliary components 1031 are two second matching panels with different functions. The second matching panels can be light-transmitting glass panels (lighting), adjustable glass panels (ventilation), or other decorative panels with decorative effects. There are no restrictions here.

[0074] In the above example, panel 110 is a photovoltaic panel 101. When a certain area of ​​the wall requires greater lighting or ventilation, panel 110 can be designed as a first matching panel 102. Combined with... Figures 4-6 As shown, Figure 4 This is a schematic diagram of the arrangement of photovoltaic array structures provided in some embodiments of this application in a building. Figure 2 . Figure 5 for Figure 4 A cross-sectional view along the JJ direction. Figure 6 for Figure 4 A cross-sectional view along the KK direction. In some embodiments, the panel module 120 includes at least one photovoltaic panel 101 and an auxiliary component 103; along a first direction, the panel component 110, at least one photovoltaic panel 101 and the auxiliary component 103 are arranged sequentially.

[0075] Specifically, the arrangement of panel component 110 as the first mate with panel module 120 can be such that auxiliary component 103 in panel module 120 is arranged on the side away from the first mate, or the auxiliary component 103 is arranged on the side closer to the first mate. For example, a photovoltaic unit 10 includes a first mate, (n-1) photovoltaic panels 101, and an auxiliary component 103 arranged sequentially along a first direction; or, a photovoltaic unit 10 includes a first mate, an auxiliary component 103, and (n-1) photovoltaic panels 101 arranged sequentially along a first direction, wherein the width of photovoltaic panel 101 is B1, the width of auxiliary component 103 is B2, B2 < B1, and (n-1)B2 + B1 = B. The adjacent arrangement of the first mate and auxiliary component 103 can further meet the multi-functional requirements of the wall, and the photovoltaic panel 101 arranged on one side can also maximize the power generation area of ​​the wall.

[0076] Of course, the different arrangements of the first matching component and auxiliary component 103 in the above example can be reflected in the same photovoltaic arrangement structure, such as... Figure 4 As shown, in some embodiments, the photovoltaic array structure includes a first photovoltaic unit and a second photovoltaic unit arranged sequentially along a second direction; the first photovoltaic unit includes a panel component 110 and a panel module 120 arranged sequentially along a first direction, the panel module 120 including at least one photovoltaic panel 101 and an auxiliary component 103 arranged sequentially along the first direction; the second photovoltaic unit includes a panel component 110 and a panel module 120 arranged sequentially along the first direction, the panel module 120 including an auxiliary component 103 and at least one photovoltaic panel 101 arranged sequentially along the first direction.

[0077] Specifically, in this example, panel 110 is still the first component. In the first photovoltaic unit, auxiliary component 103 in panel module 120 is arranged on the side away from the first component. In the second photovoltaic unit, auxiliary component 103 in panel module 120 is arranged on the side closer to the first component. For example, the first photovoltaic unit includes a first component, (n-1) photovoltaic panels 101, and an auxiliary component 103 arranged sequentially along a first direction; the second photovoltaic unit includes a first component, an auxiliary component 103, and (n-1) photovoltaic panels 101 arranged sequentially along the first direction. The width of photovoltaic panel 101 is B1, and the width of auxiliary component 103 is B2, where B2 < B1, and (n-1)B2 + B1 = B. Two adjacent first components along the height direction, as well as adjacent first components and auxiliary components 103, can further meet the multi-functional requirements of the wall surface. The photovoltaic panels 101 arranged on one side can also maximize the power generation area of ​​the wall surface.

[0078] It should be noted that the auxiliary component 103 in the above example is a second matching plate. The second matching plate can be a light-transmitting glass plate (for lighting), an adjustable glass plate (for ventilation), or other decorative plates with decorative effects. There are no restrictions here.

[0079] The introduction of the first matching plate 102 and the second matching plate in the above example can save the investment in secondary design of photovoltaic array structure, which is conducive to reducing production costs and design difficulty.

[0080] When the column span spacing of a building meets the requirement of installing photovoltaic panels 101 in multiples of an integer, but certain areas of the wall require multi-functionality, combined with... Figures 10-12 As shown, Figure 10 This is a schematic diagram of the arrangement of photovoltaic array structures provided in some embodiments of this application in a building. Figure 4 . Figure 11 for Figure 10 A cross-sectional view along the OO direction. Figure 12 for Figure 10 A cross-sectional view along the PP direction. In some embodiments, the panel module 120 includes at least one photovoltaic panel 101 and an auxiliary component 103; the auxiliary component 103 includes at least one sub-photovoltaic panel 1011 and at least one sub-auxiliary component 1031 arranged sequentially along a second direction; along a first direction, the dimension of the auxiliary component 103 is A; along the second direction, the sum of the dimensions of all sub-photovoltaic panels and the dimensions of all sub-auxiliary components 1031 is L.

[0081] Specifically, in this example, the auxiliary component 103 includes not only the sub-auxiliary component 1031 but also the sub-photovoltaic panel 1011. The sub-auxiliary component 1031 is the second matching panel, which can be a translucent glass panel (for lighting), an adjustable glass panel (for ventilation), or other decorative panels with decorative effects. The width of the sub-photovoltaic panel 1011 is equal to the standard size A, and the height is less than L. It can be obtained by cutting standard-sized photovoltaic panels 101, thereby meeting the multi-functional needs of the wall surface while increasing the proportion of photovoltaic panels 101 in the photovoltaic arrangement structure to achieve the best power generation effect. Of course, this arrangement can also improve the utilization rate of photovoltaic panel 101 production materials. For example, the auxiliary component 103 includes one sub-photovoltaic panel 1011 and one sub-auxiliary component 1031.

[0082] In some embodiments, A is between 580mm and 1000mm; B is between 230mm and 2450mm; and L is between 1200mm and 2400mm.

[0083] Specifically, dimensions A and B are the standard dimensions of the photovoltaic panel 101. In particular, obtaining dimension A allows the dimensions of the panel piece 110 and panel module 120 along the first direction to be linked to the dimensions of the building (column span spacing), thereby decomposing the width of the building and providing formulaic guidance for the design of the photovoltaic unit 10 / photovoltaic layout structure, reducing the design difficulty of the photovoltaic layout structure.

[0084] This application also provides a photovoltaic curtain wall system, including multiple sets of photovoltaic arrangement structures as described in the above embodiments, such as... Figure 1 , Figure 4 , Figure 7 and Figure 10 As shown, multiple photovoltaic array structures are used for installation on the facade of a building, and the multiple photovoltaic array structures are arranged in an array on the facade of the building.

[0085] Understandably, multiple photovoltaic array structures can be arranged in an orderly array on the wall of a building along the first direction and / or the second direction. While ensuring the aesthetics of the building, this can also simplify the design of the supporting structure of the photovoltaic panel 101 and provide structural reliability.

[0086] More specifically, by dividing the photovoltaic array structure into photovoltaic units 10, further dividing the photovoltaic units 10 into panel components 110 and panel modules 120, and further dividing the panel modules 120 into photovoltaic panels 101 and / or auxiliary components 103, and by linking the dimensions of the building in the first direction (e.g., column span spacing) with the dimensions of the photovoltaic panels 101, a formulaic guide for the standard size design of the photovoltaic panels 101 is provided. On the one hand, this reduces the communication costs between architects and photovoltaic designers, shortens the design time and costs; on the other hand, it allows the overall dimensions of the photovoltaic array structure to be adapted to the dimensions of the building, facilitating the modular design of the building curtain wall, promoting the uniformity of the photovoltaic panel 101 dimensions, thereby facilitating the assembly line production of the photovoltaic panels 101, improving the production efficiency of the photovoltaic panels 101, shortening the delivery cycle, and reducing production costs. In addition, this design also helps to increase the proportion of the photovoltaic panels 101 on the building wall, making the arrangement of the photovoltaic panels 101 on the wall more reasonable, so as to achieve the best power generation effect.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
