Description

Technical Field

[0001] The present disclosure relates to a photovoltaic system, and more particularly to a photovoltaic system including a building-integrated photovoltaic (BIPV) module. Background Art

[0002] With the rapid advancement of manufacturing technology, the costs associated with the production of solar photovoltaic panels and the cost of electricity generated by solar photovoltaic panels are gradually decreasing. Therefore, building-integrated photovoltaic (BIPV) modules that combine solar photovoltaic panels with the building envelope have gradually become an attractive option for integrating power generation systems into buildings.

[0003] However, most of the commonly used building-integrated photovoltaic modules currently use brackets and frames to install solar photovoltaic panels on the roof. These brackets and frames usually require a lot of manpower, time and cost to install and maintain. For example, the traditional installation structure uses tracks to integrate photovoltaic panels into the roof structure to form a photovoltaic array. This process requires skilled labor to set up the tracks and install the photovoltaic panels on the roof structure through the tracks. This work usually needs to be done at a high altitude, which requires a lot of labor and maintenance costs.

[0004] Therefore, how to propose a photoelectric system that can solve the above problems is one of the problems that the industry is eager to invest research and development resources to solve. Summary of the invention

[0005] In view of this, an object of the present disclosure is to provide a photovoltaic system that can effectively solve the above problems.

[0006] One aspect of the present disclosure is related to a photovoltaic system including a board body, a bracket and a photovoltaic panel. The board body has a bottom plate and two side walls. The two side walls are opposite to each other and connected to the bottom plate. The bottom plate and the two side walls form a storage space. The bracket is in the storage space. The bracket includes a main part, a first side part and a second side part. The first side part extends from a first side of the main part along one of the two side walls and is coupled to the one of the two side walls. The second side part extends from a second side of the main part. The first side is adjacent to the second side. The photovoltaic panel is in the storage space and above the main part of the bracket.

[0007] In some embodiments, the stent is made of a single-piece, continuous material.

[0008] In some embodiments, a top surface of the photovoltaic panel is lower than top surfaces of the two side walls.

[0009] In some embodiments, the second side portion of the bracket extends from the second side of the main portion toward the bottom plate of the plate body by a distance greater than 1 mm.

[0010] In some embodiments, the second side portion is separated from the plate body.

[0011] In some embodiments, the first side portion is separated from the second side portion.

[0012] In some embodiments, the first side portion is connected to the second side portion.

[0013] In some embodiments, the first side portion extends along the one of the two side walls to the bottom plate and is attached to the bottom plate.

[0014] In some embodiments, the ratio between the area of ​​the main portion of the support and the area of ​​the photovoltaic panel is between 1% and 40%.

[0015] In some embodiments, a ratio between an area of ​​the first side portion of the support and an area of ​​the photovoltaic panel is between 0.3% and 10%.

[0016] In some embodiments, the support further comprises a third side portion. The third side portion is connected to one side of the first side portion. The side is opposite to the first side of the main portion. The third side portion extends away from the one of the two side walls.

[0017] In some embodiments, the photovoltaic system further comprises a cable electrically connected to the photovoltaic panel, the cable is in the accommodation space, and the cable is installed on the bracket through the third side portion.

[0018] Another aspect of the present disclosure is related to a photovoltaic system including a plate body, a bracket and a photovoltaic panel. The plate body has a bottom plate and two side walls. The two side walls are opposite to each other and connected to the bottom plate. The bottom plate and the two side walls form a storage space. The bracket is in the storage space. The bracket includes two first side portions and a second side portion. The two first side portions are respectively attached to multiple inner surfaces of the two side walls. The second side portion is located between the two first side portions. The photovoltaic panel is in the storage space. The photovoltaic panel is mounted on the bracket. The top surface of the photovoltaic panel is lower than the multiple top surfaces of the two side walls.

[0019] In some embodiments, the two first side portions extend along the plurality of inner surfaces of the two side walls respectively.

[0020] In some embodiments, the second side portion of the bracket extends toward the bottom plate of the plate body and is separated from the plate body.

[0021] In some embodiments, each of the two first side portions is separated from the second side portion.

[0022] In some embodiments, each of the two first side portions is connected to the second side portion.

[0023] In some embodiments, at least one of the two first side portions extends below the second side portion and is attached to the bottom plate.

[0024] In some embodiments, a ratio between an area of ​​one of the two first side portions of the support and an area of ​​the photovoltaic panel is between 0.3% and 10%.

[0025] In some embodiments, the photovoltaic panel is mounted to the support via a mounting surface of the support, and a ratio between an area of ​​the mounting surface and an area of ​​the photovoltaic panel is between 1% and 40%.

[0026] In summary, in the photovoltaic system of some embodiments of the present disclosure, before the roof sheet is installed, the photovoltaic panel is embedded in the accommodation space of the roof sheet through the bracket to form a module. In this way, the module can be installed using the same method as the traditional roof sheet. Therefore, there are fewer assembly steps on the roof of the building after the module is formed. Compared with the common photovoltaic system, the photovoltaic system of some embodiments of the present disclosure can reduce the time and cost associated with high-altitude work.

[0054] The following disclosure will be more fully described herein through drawings and reference materials, and some exemplary embodiments are depicted in the drawings. The disclosure may be implemented in different forms and should not be limited by the embodiments mentioned below. However, these embodiments are provided to help more fully understand the content of the disclosure and fully convey the scope of the disclosure to those skilled in the art.

[0055] In the drawings, for the sake of clarity, the thickness of layers, films, panels, regions, etc. is magnified. Throughout the specification, the same reference numerals will refer to similar elements throughout the text. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to another element, or an intermediate element can also exist. On the contrary, when an element is referred to as being "directly on" or "directly connected to" another element, there is no intermediate element. As used in the present disclosure, "connection" can refer to physical and / or electrical connection. Furthermore, "electrical connection" or "coupling" can be other elements between two elements.

[0056] It should be understood that although the terms "first", "second", "third", etc. can be used to describe various elements, components, regions, layers and / or parts in this disclosure, these elements, components, regions, and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, the "first element", "component", "region", "layer" or "part" discussed below can be referred to as a second element, component, region, layer or part without departing from the teaching of this disclosure.

[0057] The terms used herein are for the purpose of describing specific embodiments only and are not restrictive. As used in this disclosure, unless the content clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms, including "at least one". "Or" means "and / or". As used in this disclosure, the term "and / or" includes any and all combinations of one or more of the relevant listed items. It should also be understood that when used in this specification, the terms "include" and / or "include" specify the presence and / or parts of the features, regions, entireties, steps, operations, elements, but do not exclude the presence or addition of one or more other features, regions, entireties, steps, operations, elements, parts and / or their combinations.

[0058] In addition, relative terms such as "lower" or "bottom" and "upper" or "top" may be used in the present disclosure to describe the relationship of one element to another element, as shown in the figures. It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation shown in the figures. For example, if the device in a figure is turned over, the element described as being on the "lower" side of the other elements will be oriented on the "upper" side of the other elements. Therefore, the exemplary term "lower" can include both "lower" and "upper" orientations, depending on the particular orientation of the figure. Similarly, if the device in a figure is turned over, the element described as being "below" or "below" other elements will be oriented as being "above" other elements. Therefore, the exemplary term "below" or "below" can include both above and below orientations.

[0059] The use of "about", "approximately", or "substantially" in the present disclosure includes the stated value and the average value within an acceptable deviation range of the particular value determined by a person skilled in the art, taking into account the measurement in question and the specific amount of error associated with the measurement (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, the use of "about", "approximately", or "substantially" in the present disclosure can select a more acceptable deviation range or standard deviation depending on the optical properties, etching properties or other properties, and can apply to all properties without one standard deviation.

[0060] Unless otherwise defined, all terms (including technical and scientific terms) used in this disclosure have the same meaning as commonly understood by those skilled in the art. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and this disclosure, and will not be interpreted as an idealized or overly formal meaning unless explicitly defined in this disclosure.

[0061] The present disclosure describes exemplary embodiments with reference to cross-sectional views that are schematic diagrams of idealized embodiments. Therefore, variations in the shapes of the illustrations as a result of, for example, manufacturing techniques and / or tolerances are to be expected. Therefore, the embodiments described in the present disclosure should not be construed as limited to the specific shapes of the regions as shown in the present disclosure, but rather include shape deviations that result, for example, from manufacturing. For example, a region shown or described as flat may typically have rough and / or nonlinear features. In addition, sharp angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shape of the regions and are not intended to limit the scope of the claims.

[0062] Figure 1A is a schematic diagram of a photovoltaic system 10 according to some embodiments of the present disclosure. Figure 1Bis a side view of an optoelectronic system 10 according to some embodiments of the present disclosure. Figure 1C , Figure 1D , Figure 1E as well as Figure 1F It is a partially enlarged view of the optoelectronic system 10 according to some embodiments of the present disclosure.

[0063] The photovoltaic system 10 includes a plurality of modules. Each module includes a panel 100, a bracket 200 and a photovoltaic panel 300. Figure 1A and Figure 1B as shown in .

[0064] The board body 100 has a bottom plate 110 and two side walls 120. Figure 1B As shown in . The bottom plate 110 can be a corrugated plate or a box profile sheet to provide structural strength and versatility. Two side walls 120 are connected to the bottom plate 110. The two side walls 120 are opposite to each other. The bottom plate 110 and the two side walls 120 together form a storage space S. In some embodiments, the plate body 100 is used as a roof sheet. The two side walls 120 have a C-shaped structure at their tops respectively. In this way, multiple plate bodies 100 can be hinged together by the C-shaped structure. The detailed features of the C-shaped structure will be described in subsequent paragraphs. In some embodiments, the plate body 100 can be made of a continuous material formed in one piece. For example, the plate body 100 can be a substantially U-shaped plate body formed by a metal rolling process. This substantially U-shaped design is particularly beneficial for the application of roof structures because it can drain water and increase the load-bearing capacity. In some embodiments, the thickness of the plate body 100 can be between 0.2 mm and 4.6 mm.

[0065] Please refer to Figure 1C to Figure 1F , which respectively illustrate the articulation of the C-shaped structures of the side walls of the plates of two adjacent modules in different embodiments of the present disclosure. Figure 1C and Figure 1D As shown in , the C-shaped structure of the side wall 120-1 of one module and the C-shaped structure of the side wall 120-2 of another module have complementary profiles and are configured to fit tightly together. Figure 1E and Figure 1F As shown in FIG. 1 , the C-shaped structure of the side wall 120 - 1 of one module and the C-shaped structure of the side wall 120 - 2 of another module have interlocking curved sections with a gap therebetween.

[0066] Please refer again Figure 1BThe bracket 200 is located in the accommodating space S. The bracket 200 has a main portion 210 and two side portions 211. The main portion 210 spans above the bottom plate 110 of the board body 100. The two side portions 211 extend from opposite sides of the main portion 210 along the two side walls 120 of the board body 100. The bracket 200 is coupled to the two side walls 120 respectively through the two side portions 211. In some embodiments, the two side portions 211 are fastened to the inner surfaces of the two side walls 120 respectively using mechanical fasteners such as rivets and screws (not shown). These fasteners provide a firm and reliable connection to ensure the stability of the bracket 200. In other embodiments, the two side portions 211 are adhered to the inner surfaces of the two side walls 120 respectively using silicone, acrylic foam double-sided tape (VHB tape), a combination thereof, or the like. In yet other embodiments, a cold forming process may be performed to form a rivet joint between the side portion 211 and the side wall 120 to further enhance the structural strength of the bracket 200 .

[0067] In addition, the bracket 200 also includes two side portions 212 (one of the side portions 212 is not fully shown in the figure due to the angle of the drawing) for enhancing the load-bearing capacity of the bracket 200. The two side portions 212 extend downward from the other opposite sides of the main portion 210 (different from the opposite sides where the aforementioned side portions 211 are located) toward the bottom plate 110 of the plate body 100. In some embodiments, the two side portions 212 extend from the main portion 210 by a distance D. The distance D can be greater than 1 mm. For example, the distance D can be between 3 mm and 15 mm. Such an extension can ensure that the bracket 200 effectively distributes the load and maintains its structural strength under various conditions.

[0068] The photovoltaic panel 300 is located in the accommodation space S and above the main part 210 of the bracket 200. Figure 1B. The photovoltaic panel 300 may include a plurality of individual solar cells (not shown) connected to each other, but the present disclosure is not limited thereto. In some embodiments, the photovoltaic panel 300 is mounted to the mounting surface of the main portion 210 of the bracket 200 using an adhesive 220 such as a silicone resin or acrylic foam double-sided tape to ensure that the photovoltaic panel 300 is firmly held in place. The top surface of the photovoltaic panel 300 is lower than the top surface of the side wall 120. In other words, the photovoltaic panel 300 is not higher than the side wall 120, so that the module of the photovoltaic system 10 is an embedded structure. This embedded structure has multiple advantages, including enhanced protection of the photovoltaic panel 300 from environmental impact and a more streamlined appearance. In some embodiments, before installing the photovoltaic panel 300, two to ten brackets 200 can be attached to the board body 100 to evenly distribute the load of the photovoltaic panel 300 on these brackets 200 and enhance the overall durability of the photovoltaic system 10.

[0069] Please refer to Figure 2 . Figure 2 is a perspective view of a bracket 200 according to some embodiments of the present disclosure. In these embodiments, the main portion 210 is substantially rectangular. As described above, the two side portions 211 extend from two opposite sides of the main portion 210, respectively, and the two side portions 212 extend from the other two opposite sides of the main portion 210, respectively. For example, one of the side portions 211 extends from a first side 210a of the main portion 210, and one of the side portions 212 extends from a second side 210b of the main portion 210. The first side 210a is adjacent to the second side 210b. In some embodiments, each side portion 212 is located between the two side portions 211 and is separated from the two side portions 211. In this configuration, the bracket 200 can be made of a continuous material formed in one piece. For example, the bracket 200 can be made of a metal plate formed using metal stamping or casting. In some embodiments, the thickness of the metal plate forming the bracket 200 can be between 0.6 mm and 3 mm. In addition, please refer again to Figure 1B The side portion 212 is separated from the side wall 120 of the board body 100, and the side portion 212 is separated from the bottom plate 110 of the board body 100. In addition, the bracket 200 is separated from the bottom plate 110 of the board body 100.

[0070] In order to ensure that the bracket 200 provides sufficient support for the photovoltaic panel 300, the ratio of the area of ​​the mounting surface of the main part 210 to the area of ​​the photovoltaic panel 300 is between 1% and 40%. At the same time, in order to ensure sufficient structural strength to fix the bracket 200 and the photovoltaic panel 300 on the board body 100, the ratio of the area of ​​the side part 211 of the bracket 200 to the area of ​​the photovoltaic panel 300 is between 0.3% and 10%.

[0071] By integrating the photovoltaic panel 300 into the accommodation space S of the panel body 100 using the bracket 200, an embedded building integrated photovoltaic (BIPV) module is formed. This embedded module can be used as a support structure when the photovoltaic panel 300 is connected. The embedded module can be installed on the roof in a manner similar to a traditional roof sheet. In addition, since the bracket 200 and the photovoltaic panel 300 are pre-installed before the embedded module is installed on the roof, the assembly steps on the roof of the building after the embedded module is in place can be simplified. This pre-assembly can not only simplify the installation, but also reduce the risk of high-altitude operations.

[0072] Please refer to Figure 3 . Figure 3 is a perspective view of a bracket 200A according to some embodiments of the present disclosure. The difference between bracket 200A and bracket 200 is that bracket 200A has a plurality of slots. The slots are provided for a dual purpose: the slots can reduce the overall weight of bracket 200A and facilitate the installation of rivets or a cinch process. Specifically, the slots are strategically provided to ensure that the required structural strength is maintained despite the reduction in material used in bracket 200A. In addition, the slots allow a riveting tool or a cinch tool to access the side portion 211 from above, so that the side portion 211 can be more easily riveted or cold formed to the side wall 120. This design can simplify the assembly process and ensure that bracket 200A can be attached more effortlessly and securely.

[0073] Please refer to Figure 4 . Figure 4 is a perspective view of a bracket 200B according to some embodiments of the present disclosure. The difference between the bracket 200B and the bracket 200 is that the side portion 211 and the side portion 212 of the bracket 200B are connected to each other to improve the structural strength of the bracket 200B. In detail, the bracket 200B can be an integrally formed sheet metal box. The sheet metal box has two opposite inclined side walls and two opposite vertical side walls. Among them, the two opposite inclined side walls correspond to the aforementioned side portion 211, and the two opposite vertical side walls correspond to the aforementioned side portion 212. This configuration ensures that the bracket 200B can better withstand various stresses and loads.

[0074] Please refer to Figure 5 and Figure 6 . Figure 5 is a perspective view of a bracket 200C according to some embodiments of the present disclosure. Figure 6 is a schematic diagram of an optoelectronic system 10 ′ according to some embodiments of the present disclosure.

[0075] The difference between the bracket 200C and the bracket 200 is that the bracket 200C further includes two side portions 213. The two side portions 213 correspond to the two side portions 211. Each side portion 213 is connected to a side of the corresponding side portion 211 away from the main portion 210 (for example, a side of the side portion 211 opposite to the first side 210a of the main portion 210). Each side portion 213 extends toward the main portion 210 and is located below the side portion 212, forming a V shape.

[0076] The difference between the photovoltaic system 10' and the photovoltaic system 10 is that the photovoltaic system 10' includes Figure 5 The bracket 200C shown in FIG. 1 is electrically connected to the cable 400 of the photovoltaic panel 300. Figure 6 As shown in , after the bracket 200C is coupled to the panel body 100, each side portion 213 extends in a direction away from the side wall 120 adjacent thereto and toward the main portion 210. The cable 400 is located on one of the side portions 213, thereby being mounted to the bracket 200C. In addition, the cable 400 is located between the main portion 210 and the aforementioned side portion 213. In this way, the cable 400 is accommodated below the photovoltaic panel 300 and in the accommodation space S, which can prevent the cable 400 from being entangled with other cables. This configuration facilitates more efficient cable management of large photovoltaic systems, thereby reducing the maintenance requirements during the service life of the photovoltaic system.

[0077] Please refer to Figure 7 and Figure 8 . Figure 7 is a perspective view of a bracket 200D according to some embodiments of the present disclosure. Figure 8 is a side view of an optoelectronic system 10 ″ according to some embodiments of the present disclosure.

[0078] The difference between the bracket 200D and the bracket 200 is that the side portion 211 of the bracket 200D further extends away from the main portion 210 and extends below the side portion 212. Figure 7 As shown in FIG. 2 , the extended portion of the side portion 211 is bent inwardly to form a C-shape.

[0079] The difference between the photovoltaic system 10 ″ and the photovoltaic system 10 is that the photovoltaic system 10 ″ includes Figure 7The bracket 200D shown in FIG. The side portion 211 of the bracket 200D extends and bends along the inner surface of the side wall 120, and reaches the bottom plate 110 downward. Then, the side portion 211 along the side wall 120 is attached to the side wall 120 using an adhesive 130, and the side portion 211 above the bottom plate 110 is attached to the bottom plate 110 using an adhesive 140. In some embodiments, the adhesive 130 and the adhesive 140 can be silicone resin, acrylic foam double-sided tape, a combination thereof, or the like. In these embodiments, the structural strength of the bracket 200D is further improved.

[0080] From the above detailed description of the specific embodiments of the present disclosure, it can be clearly seen that in the photovoltaic system of some embodiments of the present disclosure, before the roof sheet is installed, the photovoltaic panel is embedded in the accommodation space of the roof sheet through the bracket to form a module. In this way, the module can be installed using the same method as the traditional roof sheet. Therefore, there are fewer assembly steps on the roof of the building after the module is formed. Compared with the common photovoltaic system, the photovoltaic system of some embodiments of the present disclosure can reduce the time and cost associated with high-altitude work.

[0081] The foregoing description is provided only to illustrate and describe exemplary embodiments of the present disclosure and is not intended to be exhaustive or to limit the precise forms of the invention disclosed in the present disclosure. The above teachings may be modified or varied.

[0082] The embodiments selected and described are intended to explain the content of the present disclosure and their practical applications so as to inspire those skilled in the art to utilize the present disclosure and various embodiments, and to make various modifications to meet the specific intended use. Alternative embodiments will be apparent to those skilled in the art without departing from the spirit and scope of the present disclosure.
