Description

Technical Field

[0001] The present invention relates to a unit block type photovoltaic module, and more particularly to a unit block type photovoltaic module that can be used as an exterior material and an insulation material for a building. Background Art

[0002] Recently, the use of solar power generation facilities using solar power has become increasingly widespread. Solar cells that utilize solar energy use sunlight, which is a pollution-free and infinite energy source, instead of fossil fuels such as coal or oil, and thus are attracting attention as a new alternative energy source for the future. Currently, solar cells are used to generate electricity for solar power plants, buildings, and automobiles.

[0003] Generally, solar power generation is a technology that directly generates electricity using solar cells (photovoltaic: PV). These solar cells are semiconductor devices that convert light energy into electrical energy using the photovoltaic effect, and include two semiconductor thin films, each having a positive (+) polarity and a negative (-) polarity. A plurality of solar cell units are connected in series and in parallel to generate the voltage and current required by the user, and the user can use the electricity generated by these solar cells.

[0004] Unlike other alternative energy utilization technologies, solar power generation systems have a simple system configuration, and active efforts are being made to apply solar power generation systems to the field of building construction. For example, building-attached photovoltaics (BAPV) and building-integrated photovoltaics (BIPV), which attach photovoltaic modules to the roofs or exterior walls of buildings, have been widely concerned.

[0005] In particular, the most representative example is BIPV, which integrates existing building materials with solar cells and performs both building material functions and power generation functions at the same time.

[0006] However, BIPV products have not been standardized and are produced as custom products according to building designs, which makes the unit price of BIPV products high and it is difficult to ensure their economic feasibility.

[0007] In addition, most products are set up such that building roof and facade insulation materials are separately installed and then solar cells are added, which results in a long and complex construction period.

[0008] On the other hand, when a solar cell module is used as an exterior material of a building, it has a backsheet on its back side, and the backsheet is highly flammable and may emit harmful gases in the event of a fire. In addition, an air layer is formed between the solar cell module and the building insulator to provide cooling, but when such a solar cell module is installed on a building facade, it becomes highly dangerous because the chimney effect may cause the fire to spread in the event of a fire.

[0009] Accordingly, the Seoul Metropolitan Government recommends that only GtG (glass-to-glass) type solar cell modules be used for BIPV products. Such products use glass on the back side instead of a backsheet, but the heat transfer rate of the glass is very low, making it difficult to effectively dissipate the heat accumulated from receiving sunlight. SUMMARY OF THE INVENTION

[0021] The support portion is provided with a placement groove at its front surface, and the power generation portion may be inserted and attached into the placement groove such that the surface of the power generation portion may be coplanar with the surface of the support portion.

[0022] The support portion may include: a substrate formed in a quadrilateral shape having a predetermined area; four side plates bent from the edges of the substrate; and coupling portions extending from each of the side plates.

[0042] Hereinafter, examples of the present invention will be described in detail with reference to the drawings. The following examples are provided to fully convey the spirit of the present invention to those of ordinary skill in the art to which the present invention pertains. The present invention is not limited to the examples shown herein, but may be embodied in other forms. For the description of the present invention to be clear, irrelevant parts are not shown, and the dimensions of the components are exaggerated for clarity.

[0043] Figure 1 is an exploded perspective view showing a unit block type photovoltaic module according to an embodiment of the present invention, Figure 2 is Figure 1Isometric view of the assembly, Figure 3 Is a sectional view showing a unit block type photovoltaic module according to an embodiment of the present invention, Figure 4 Is a view showing an example of assembling a unit block type photovoltaic module according to an embodiment of the present invention to an adjacent photovoltaic module, Figure 5 Is Figure 4 Assembly diagram of, and Figure 6 Is a view showing an example of assembling a plurality of photovoltaic modules to a unit block type photovoltaic module according to an embodiment of the present invention.

[0044] Referring to Figures 1 to 6 , the unit block type photovoltaic module 1 according to one aspect of the present invention can be configured to be used as an exterior material of a building while ensuring insulation. The unit block type photovoltaic module 1 is manufactured in a standardized size to allow mass production, and can also be arranged to allow fastening on all sides to cover the entire facade of the building.

[0045] The unit block type photovoltaic module 1 may include: a support part 100 having a coupling part 140 provided to allow coupling with an adjacent unit block type photovoltaic module 1 on all sides; a power generation part 200 attached to the front surface of the support part 100 to generate electricity using solar energy; and an insulation part 300 provided in the support part 100.

[0046] The support part 100 is fixed to the wall surface 10 of the building and is used to support the power generation part 200, and the support part 100 can be formed by bending a metal plate having a predetermined stiffness. In addition, since the support part 100 is formed of a metal plate, the heat generated from the power generation part 200 is transferred to the wall surface 10, thereby improving the heat dissipation performance.

[0047] In addition, the support part 100 can be formed of a steel plate which is a non-combustible material to prevent the combustion and emission of harmful gases in the event of a fire. For example, the support part 100 can be formed of a highly corrosion-resistant steel plate selected from the group including galvanized steel plates, magnesium-zinc-coated steel plates, magnesium-zinc-aluminum-coated steel plates, and stainless steel plates. The steel plate forming the support part 100 preferably has a thickness of 0.8 mm to 1.5 mm, and more preferably can be formed to have a thickness of 1.0 mm to 1.2 mm. When the thickness is less than 0.8 mm, the durability (strength) as a frame cannot be ensured, which is not desirable, and when the thickness exceeds 1.5 mm, the weight increases, which is not desirable in terms of light weight.

[0048] In addition, since the support part 100 is used as an exterior material of the building, the support part 100 can be formed of a steel plate capable of exhibiting texture and color to enhance the aesthetic appearance.

[0049] The support part 100 can be configured to have a cavity part 130 so as to form an accommodation space therein. More specifically, the support part 100 can include a substrate 110, side plates 120 bent from the edges of the substrate 110, and a coupling part 140 extending from the side plates 120. That is, the support part 100 can be configured to be open on one side through the substrate 110 and the side plates 120 to form the cavity part 130.

[0050] The substrate 110 can be configured to have a quadrilateral shape with a predetermined area. The substrate 110 can attach the power generation part 200 to its front surface, thus serving as the substrate of the power generation part 200.

[0051] The side plates 120 can be formed on the edges of the substrate 110 having a quadrilateral shape, and thus are provided as four side plates. Therefore, the side plates 120 can be classified as first to fourth side plates 121, 122, 123, and 124 in the order of right, up, left, and down directions based on the Figure 1 illustrated diagram. That is, among the first to fourth side plates 121 to 124, the first side plate 121 and the third side plate 123 on the right and left sides, and the second side plate 122 and the fourth side plate 124 on the upper and lower sides can be arranged to face each other. It should be understood that the directions described herein are based on the illustrated diagram and are not limited thereto, and can vary according to the viewing direction.

[0052] The coupling part 140 can be formed to extend from each of the four side plates 121 to 124 so as to be coupled to an adjacent unit block type photovoltaic module 1. Additionally, the coupling part 140 can include a pair of fastening parts 141 and 142 formed on the facing side plates 120. That is, a pair of fastening parts 141 and 142 can also be provided on the facing first side plate 121 and third side plate 123, and on the facing second side plate 122 and fourth side plate 124.

[0053] A pair of fastening parts 141 and 142 can include: a first fastening part 141 that protrudes outward from one of the opposing side plates 120; and a second fastening part 142 that is bent to form a fastening groove 143 into which the first fastening part 141 is inserted. In this case, the second fastening part 142 can be formed on the side plate 120 opposite to the side plate 120 on which the first fastening part 141 is formed.

[0054] For example, when the first fastening portion 141 is formed on the first side plate 121, the second fastening portion 142 may be formed on the third side plate 123. Additionally, when the second fastening portion 142 is formed on the first side plate 121, the first fastening portion 141 may be formed on the third side plate 123. Similarly, the second side plate 122 and the fourth side plate 124 may also be optionally provided with the first fastening portion 141 and the second fastening portion 142. Thus, by coupling the first fastening portion 141 and the second fastening portion 142 to each other, continuous coupling with an adjacent unit block type photovoltaic module 1 can be achieved.

[0055] The first fastening portion 141 or the second fastening portion 142 may include a fixing portion 144 fixed to the wall surface 10 of the building by the fastening portion 150. Details of the structure fixed by the fastening portion 150 and the fixing portion 144 will be described below.

[0056] Meanwhile, based on Figure 3 the illustrated diagram, the coupling portion 140 may be provided to be located below the power generation portion 200. That is, the first fastening portion 141 and the second fastening portion 142 may be formed to extend from the end portion of the side plate 120 bent from the base plate 110.

[0057] More specifically, based on the illustrated diagram, the first fastening portion 141 may be formed on the second side plate 122 and the third side plate 123. The first fastening portion 141 may be bent at the second side plate 122 and the third side plate 123 and project radially outward from the second side plate 122 and the third side plate 123. The first fastening portion 141 may be bent at an angle of 90 degrees to ensure stable coupling with an adjacent unit block type photovoltaic module 1.

[0058] Based on the illustrated diagram, the second fastening portion 142 may be formed on the first side plate 121 and the fourth side plate 124. The second fastening portion 142 may be bent to form a fastening groove 143 into which the first fastening portion 141 is inserted and coupled. That is, the second fastening portion 142 may be bent multiple times to radially inwardly form the fastening groove 142 while radially outwardly projecting at its end portion. In this case, it should be understood that the formation position of the fastening groove 142 and the formation position of the first fastening portion 141 are set to be coplanar with each other.

[0059] Such a pair of fastening portions 141 and 142 can not only contribute to coupling with an adjacent unit block type photovoltaic module 1, but also serve as the fixing portion 144 to be fixed to the wall surface 10 of the building. For example, the second fastening portion 142 may be provided with the fixing portion 144 extending from the end portion of the second fastening portion 142.

[0060] The fixed part 144 is set to be in surface contact with the wall surface 10 and has fastening holes 145 that can be fixed to the wall surface 10 through the fastening part 150. The fastening part 150 can be set as a common fastening part such as a bolt, a nail, a screw, or a part.

[0061] The power generation part 200 can be set to be attached to the front surface of the support part 100 and generate electricity using solar energy. The power generation part 200 can include a plurality of solar cells 210, a film layer 220 set to cover the upper and lower surfaces of the plurality of solar cells 210, a cover window 230 attached to the upper surface of the film layer 220, and a bus bar 240 connected to the plurality of solar cells 210.

[0062] The solar cell 210 performs direct current (DC) generation by absorbing the energy from incident sunlight through the photovoltaic effect and can be manufactured by joining a positive (P) type semiconductor and a negative (N) type semiconductor. The solar cell 210 generates holes (+) and electrons (-) through the energy of sunlight. The holes gather toward the P-type semiconductor, and the electrons gather toward the N-type semiconductor, thereby generating a potential difference and supplying current to the outside.

[0063] The solar cells 210 can be repeatedly arranged at regular intervals, for example, repeatedly arranged in a grid shape, and can be formed of crystalline silicon such as monocrystalline silicon and polycrystalline silicon or amorphous silicon. In this case, four solar cells 210 are shown to be provided in a single unit block type photovoltaic module 1, but the number, shape, and type of the solar cells 210 can vary according to the size of the module.

[0064] The film layer 220 can be set to cover the upper and lower surfaces of the solar cells 210. That is, the film layer 220 can be set as an upper film layer 221 that covers the upper surface of the solar cells 210 and a lower film layer 222 that covers the lower surface of the solar cells 210. The film layer 220 can be set as an ethylene vinyl acetate (EVA) copolymer. The film layer 220 is used to protect the solar cells 210 from external foreign matters and enhance the durability of the solar cells 210.

[0065] In addition, when the power generation part 200 is attached to the front surface of the support part 100, the upper film layer 221 and the lower film layer 222 can be heated to form a single film layer 220 that surrounds the solar cells 210.

[0066] The cover window 230 is attached to the upper surface of the film layer 220 and is used to protect the solar cells 210. The cover window 230 can be set to have a color. For example, the cover window 230 can be set to have the same color as the support part 100. Since the cover window 230 is set to have a color, the solar cells 210 can be hidden and not recognized externally, thereby enhancing the aesthetic appearance as a building decoration material.

[0067] In addition, the cover window 230 may be formed of glass or a transparent polymer material.

[0068] The bus bar 240 is connected to the solar cell 210. The bus bar 240 is in direct contact with the upper surface of the outermost solar cell 210 and is thus connected to the solar cell 240. The bus bar 240 may be connected to the junction box 400 by a conductor 244. In this case, the junction box 400 may be disposed in the cavity portion 130, and since the substrate 110 of the support portion 100 serves as the substrate of the solar cell 210, the support portion 110 may have a through hole 114 through which the conductor 244 may pass and be connected to the junction box 400. Accordingly, the conductor 244 is connected to the junction box 400 through the through hole 114. In this case, the insulator 134 may be provided to surround the edge of the through hole 114 to prevent the connection between the conductor 244 and the support portion 100.

[0069] Meanwhile, since the junction box 400 is disposed in the cavity portion 130, the support portion 100 may be provided with a first connector 410 and a second connector 420 such that when connected to an adjacent unit block type photovoltaic module 1, the positive / negative direct current can be separated to provide connection. For example, the first connector 410 may be connected to the junction box 400 via a cable 430 to connect to the positive (+) direct current, and the second connector 420 may be connected to the junction box 400 via a cable 430 to connect to the negative (-) direct current.

[0070] The first connector 410 may be connected to the second connector 420 when assembled with an adjacent unit block type photovoltaic module 1, and the second connector 420 may be connected to the first connector 410. Accordingly, the first connector 410 and the second connector 420 may be installed such that portions of the first connector 410 and the second connector 420 are exposed to the outside from the support portion 100. That is, connection holes 125 may be formed in the portions of the side plate 120 of the support portion 100 where the first connector 410 and the second connector 420 are installed to allow the installation of the connectors 410 and 420.

[0071] The isolation portion 300 may be formed by filling the cavity portion 130 with a filler. The isolation portion 300 may include insulation materials commonly used in buildings and may be formed of expanded polystyrene (EPS), polyurethane, and glass wool materials, which can ensure higher performance than semi-combustible materials.

[0072] As described above, the unit block type photovoltaic module 1 according to the present invention is provided as a single unit and is selectively assembled on all sides, thereby serving as an external material of a building while serving as an insulation material.

[0073] Meanwhile, the unit-block type photovoltaic module 1 is shown and described with the power generation part 200 attached to the front surface of the substrate 110 of the support part 100. However, the power generation part 200 can be arranged and attached to the support part 100 to ensure process convenience, aesthetic quality, and stability. In Figure 7 the unit-block type photovoltaic module 1 is shown.

[0074] Figure 7 is a cross-sectional view showing a modified example of the support part provided in the unit-block type photovoltaic module according to an embodiment of the present invention. In the following description, the same reference numerals as those used in the above drawings denote components that perform the same functions.

[0075] Referring to Figure 7 , the unit-block type photovoltaic module 1 according to the present embodiment may further have a mounting groove 112 recessed inward from the front surface of the substrate 110 of the support part 100. That is, the power generation part 200 can be inserted and attached to the mounting groove 112. In this case, the thickness of the power generation part 200 and the depth of the fixing groove 112 can be set to correspond to each other. Therefore, the surface of the power generation part 200 and the surface of the support part 100 can be arranged to be coplanar with each other.

[0076] Meanwhile, the unit-block type photovoltaic module 1 is shown and described as being laterally assembled when coupled to an adjacent unit-block type photovoltaic module 1, but is not limited thereto, and can also be longitudinally assembled. In Figure 8 and Figure 9 the structure of such a unit-block type photovoltaic module 1 is shown.

[0077] Figure 8 is a cross-sectional view showing a modified example of the coupling part provided in the unit-block type photovoltaic module according to an embodiment of the present invention, and Figure 9 is a view showing the assembled state with an adjacent unit-block type photovoltaic module through the coupling part shown in Figure 8 . In the following description, the same reference numerals as those used in the above drawings denote components that perform the same functions.

[0078] According to the present embodiment, the unit-block type photovoltaic module 1 can be provided with a coupling part that is longitudinally coupled to an adjacent unit-block type photovoltaic module 1.

[0079] The coupling part 140' includes a pair of fastening parts 141' and 142', and the pair of fastening parts 141' and 142' may include a first fastening part 141' and a second fastening part 142'. In this case, different from the previous embodiment, the coupling part 140' according to the present embodiment can be arranged to be located above the power generation part 200.

[0080] More specifically, the first fastening portion 141' may be formed to extend upward from the side plate 120 of the support portion 100 and may be inclined and bent from an extension portion of the first fastening portion 141'.

[0081] The second fastening portion 142' may be formed to extend upward from the side plate 120, but may be bent to form a fastening groove 143' into which the first fastening portion 141' is inserted. That is, the second fastening portion 142' may be arranged to extend upward from the side plate 120 and bent multiple times so that the first fastening portion 141' can be inserted. In this case, the second fastening portion 142' may be provided with an inclined locking portion such that when the first fastening portion 141' is coupled to the second fastening portion 142', the inclined portion of the first fastening portion 141' engages with the locking portion to prevent separation.

[0082] That is, through the above pair of fastening portions 141' and 142', the unit block type photovoltaic module 1 can be continuously connected and assembled in the longitudinal direction.

[0083] Such a pair of fastening portions 141' and 142' are not only used to provide connection with an adjacent unit block type photovoltaic module 1, but also serve as a fixing portion 144' for fixing to the wall surface 10 of a building. For example, it may include a fixing portion 144' that is coupled to the first fastening portion 141' and fixed to the wall surface 10.

[0084] The fixing portion 144' may be arranged to be coupled to the first fastening portion 141' and in surface contact with the wall surface 10. The fixing portion 144' may be provided separately and may be fixed to the wall surface 10 by a fastening portion 150. The fastening portion 150 may be arranged as a common fastening member such as a bolt, a nail, a screw, or a part.

[0085] Meanwhile, the unit block type photovoltaic module 1 according to the present embodiment may be arranged such that the power generation portion 200 is disposed and attached to the front surface of the substrate 110 of the support portion 100 as in the previous embodiment. In Figure 10 the unit block type photovoltaic module 1 is shown.

[0086] Figure 10 is a cross-sectional view showing a modified example of the support portion provided in the unit block type photovoltaic module shown in Figure 8 In the following description, the same reference numerals as those used in the above drawings denote members having the same functions.

[0087] Refer to Figure 10, the unit block type photovoltaic module 1 according to the embodiment may further have a placement groove 112 recessed inward from the front surface of the substrate 110 of the support portion 100. That is, the power generation portion 200 may be inserted and attached to the installation groove 112. In this case, the thickness of the power generation portion 200 and the depth of the installation groove 112 may be set to correspond to each other. Therefore, the surface of the power generation portion 200 and the surface of the support portion 100 may be set to be coplanar with each other.

[0088] As described above, the unit block type photovoltaic module 1 including various modification examples can be used as an exterior material of a building by continuously coupling with adjacent unit block type photovoltaic modules 1 in the longitudinal or transverse direction, and the insulation performance is ensured by the insulation material provided inside.

[0089] In addition, by arranging the power generation portion 200 in the placement groove 112 of the support portion 100, not only can the aesthetic appearance be improved, but also the power generation portion 200 can be prevented from being exposed to danger in the event of a fire.

[0090] Although the exemplary embodiments of the present disclosure have been described above with reference to the drawings, those of ordinary skill in the art will understand that various modifications and changes can be made without departing from the spirit and scope of the present disclosure defined by the appended claims.
