Description

[Technical Field]

[0001] The present invention relates to a unit-type solar module, and more particularly to a unit-type solar module that can be used as an exterior material and a heat insulating material for a building. [Background technology]

[0002] In recent years, the use of solar power generation facilities that can generate electricity using solar energy has become increasingly common. Solar cells that utilize solar energy are attracting attention as a new alternative energy source of the future because they do not use fossil fuels such as coal or oil and instead use sunlight, a pollution-free and unlimited energy source. Currently, they are used to generate electricity for solar power plants, buildings, automobiles, etc.

[0003] Generally, solar power generation is a technology that directly generates electricity using photovoltaic solar cells (PV). Such solar cells are semiconductor devices that convert light energy into electrical energy using the photoelectric effect, and consist of two semiconductor thin films, each with a positive (+) and negative (-) polarity. A large number of solar cells are connected in series or parallel to generate the voltage and current required by the user, and the user can then use the electricity generated from these solar cells.

[0004] Unlike other alternative energy utilization technologies, solar power generation systems are simple to configure, and in recent years, there have been many efforts to apply them to the building sector. For example, technologies such as BAPV (Building Attached Photovoltaic) and BIPV (Building Integrated Photovoltaic), which attach solar modules to the rooftops or exterior walls of buildings, have been attracting attention.

[0005] The most representative of these is building-integrated photovoltaics (BIPV), which combines existing building materials with solar cells to simultaneously function as a building material and generate electricity.

[0006] However, BIPV products are not yet standardized and are made to order according to building designs, which means the unit price is high and it is difficult to ensure economic viability.

[0007] In addition, most products require separate installation of insulation materials on the roof and facade of a building before adding solar cells, which results in long and complicated installation times.

[0008] On the other hand, when used as an exterior material for a building, a backsheet is attached to the rear of the solar cell module, which has the problem of being easily ignited in the event of a fire and generating harmful gases. Also, an air layer for cooling is formed between the solar cell module and the building's insulation, and if such a solar cell module is installed on the building's facade, it is very dangerous because the chimney effect causes the fire to spread rapidly in the event of a fire.

[0009] In response, Seoul City is proposing to use only GtG (glass to glass) type solar cell modules for BIPV products, which do not use a backsheet on the rear surface and can be replaced with glass. However, glass has a very low thermal conductivity, which makes it difficult to effectively release the heat that rises when sunlight is received. Summary of the Invention [Problem to be solved by the invention]

[0010] The unit type solar module according to one embodiment of the present invention can be used as an exterior material for a building, and can simultaneously ensure thermal insulation and effectively dissipate heat from the module.

[0011] The unit type solar module according to an embodiment of the present invention can be easily fastened on all four sides, and can be flexibly adapted to the area to be installed, minimizing unused area. [Means for solving the problem]

[0012] According to one aspect of the present invention, a unit-type solar module can be provided that includes a support part having a pocket part formed therein to form a storage space and a connecting part that allows it to be connected to an adjacent unit-type solar module from all sides, a power generation part that is attached to the front surface of the support part and generates electricity using sunlight, and a heat insulating part that is formed by filling the pocket part with a filling material, and the connecting part is extended from the support part and is arranged to be located on the outer periphery of the power generation part.

[0013] The power generation unit may include a plurality of solar cells arranged repeatedly at predetermined intervals, a film layer provided to cover the upper and lower surfaces of the solar cells, a cover window attached to the upper surface of the film layer, and a bus bar connected to the plurality of solar cells.

[0014] The cover window may be provided to have the same color as the support.

[0015] The electric motor may further include a junction box disposed in the pocket and connected to the bus bar by a conductor.

[0016] The junction box may further include first and second connectors connected to the junction box via cables so that + / - DC electricity is separated on both sides of the junction box and connected to adjacent unit-type solar modules.

[0017] The support portion may have a connection hole formed therein so that a portion of the first and second connectors is exposed to the outside.

[0018] A through hole may be formed in the support portion so that the conductor passes through, and an insulator may be provided in the through hole to prevent connection between the conductor and the support portion.

[0019] The front surface of the support portion may be provided with a seating groove into which the power generation portion is inserted and attached so that the surface of the power generation portion and the surface of the support portion are positioned on the same line.

[0020] The support portion may include a base plate having a rectangular shape with a predetermined area, four side plates formed by bending from the edges of the base plate, and the connecting portion extending from each of the side plates.

[0021] The coupling portion may be positioned above or below the power generation portion based on the power generation portion, and may include a pair of fastening portions formed on side plates facing each other.

[0022] The pair of fastening portions may include a first fastening portion formed by protruding outward from one of the opposing side panels, and a second fastening portion bent to form a fastening groove into which the first fastening portion can be inserted, and the second fastening portion may be formed on the side panel opposite to where the first fastening portion is formed.

[0023] The first fastening portion or the second fastening portion may include a fixing portion provided to be fixed to a wall surface of a building via a fastening member.

[0024] The support portion is formed by bending a metal plate having a predetermined rigidity, and the metal plate may be provided to have a thickness of 0.8 mm to 1.5 mm. [Effects of the Invention]

[0025] The unit type solar module according to one embodiment of the present invention can be used as an exterior material for a building, and has the effect of ensuring heat insulation and effectively dissipating heat from the module.

[0026] In addition, the unit-type solar module according to one embodiment of the present invention is manufactured to have a standardized size to enable mass production, and has the advantage of being easily fastened from all four sides, allowing it to flexibly accommodate the area to be installed and minimize unused area.

[0027] In addition, by using a metal plate with high thermal conductivity to dissipate heat, the power generation efficiency of the solar module can be improved.

[0028] In addition, since there is no space for air cooling between the conventional back sheet and outer wall and the module, the risk of fire spreading due to the chimney effect can be prevented, and fire safety can be ensured by installing the power generation unit in a groove in the support unit.

[0039] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following examples are presented to fully convey the spirit of the present invention to those skilled in the art to which the present invention pertains. The present invention is not limited to the embodiments presented in this specification and may be embodied in other forms. In the drawings, parts that are not relevant to the description may be omitted to clarify the present invention, and the size of components may be somewhat exaggerated to facilitate understanding.

[0040] FIG. 1 is an exploded perspective view showing a unit-type solar module according to one embodiment of the present invention, FIG. 2 is an assembled perspective view of FIG. 1, FIG. 3 is a cross-sectional view showing a unit-type solar module according to one embodiment of the present invention, FIG. 4 is a view showing a unit-type solar module according to one embodiment of the present invention assembled with an adjacent solar module, FIG. 5 is an assembly view of FIG. 4, and FIG. 6 is a view showing a unit-type solar module according to one embodiment of the present invention with multiple solar modules assembled.

[0041] 1 to 6, a unit-type solar module 1 according to one embodiment of the present invention can be used as an exterior material for a building and can be configured to ensure thermal insulation. Such a unit-type solar module 1 can be manufactured to a standardized size to enable mass production, and can be fastened on all four sides to cover the entire facade of a building.

[0042] Such a unit-type solar module 1 may include a support part 100 provided with connecting parts 140 so as to be connected to adjacent unit-type solar modules 1 from all sides, a power generation part 200 attached to the front surface of the support part 100 and generating electricity using sunlight, and a heat insulation part 300 provided on the support part 100.

[0043] The support unit 100 is fixed to the wall surface 10 of the building to support the power generation unit 200, and can be formed by bending a metal plate having a predetermined rigidity. In addition, since the support unit 100 is made of a metal plate, it can transfer heat generated from the power generation unit 200 to the wall surface 10, thereby improving heat dissipation performance.

[0044] Furthermore, the support portion 100 may be made of a non-combustible steel plate so that it will not burn in the event of a fire and will not emit harmful gases. For example, the support portion 100 may be made of a highly corrosion-resistant steel plate selected from the group consisting of a zinc-plated steel plate, a magnesium-zinc-plated steel plate, a magnesium-zinc-aluminum-plated steel plate, and a stainless steel plate. The steel plate constituting the support portion 100 preferably has a thickness of 0.8 mm to 1.5 mm, and more preferably has a thickness of 1.0 mm to 1.2 mm. A thickness of less than 0.8 mm is not preferable because the durability (strength) of the frame cannot be ensured, while a thickness of more than 1.5 mm is not preferable from the perspective of weight reduction due to the increased weight.

[0045] In addition, the support part 100 can be made of a steel plate that can express texture and color to enhance beauty by serving as an exterior material of the building.

[0046] The support 100 may be provided with a pocket 130 to have a storage space therein. More specifically, the support 100 may include a base plate 110, a side plate 120 formed by bending from an edge of the base plate 110, and a coupling portion 140 formed by extending from the side plate 120. That is, the support 100 is provided in a form in which one side is open by the base plate 110 and the side plate 120, so that the pocket 130 may be formed.

[0047] The base plate 110 can be provided in a rectangular shape having a predetermined area. The power generation unit 200 is attached to the front surface of the base plate 110, and serves as a substrate for the power generation unit 200.

[0048] The side panels 120 may be provided on the edges of the rectangular base panel 110, and may consist of four side panels. Therefore, the side panels 120 may be divided into first through fourth side panels 121, 122, 123, and 124 in the order of right, upper, left, and lower directions based on the view shown in FIG. 1 . That is, among the first through fourth side panels 121 through 124, the first side panel 121 and the third side panel 123 on the right and left sides, and the second side panel 122 and the fourth side panel 124 on the upper and lower sides may be provided to face each other. It should be understood that the directions indicated herein are not limited to those described based on the illustrations, and may be changed depending on the viewing direction.

[0049] The coupling portions 140 may be formed by extending from each of the four side panels 121 to 124 and provided to couple to adjacent unit-type solar modules 1. The coupling portions 140 may include a pair of fastening portions 141, 142 formed on each of the side panels 120 facing each other. That is, the pair of fastening portions 141, 142 may be provided on the first side panel 121 and the third side panel 123, and the second side panel 122 and the fourth side panel 124 facing each other, respectively.

[0050] The pair of fastening portions 141, 142 may include a first fastening portion 141 formed by protruding outward from one of the opposing side plates 120, and a second fastening portion 142 bent to form a fastening groove 143 into which the first fastening portion 141 is inserted. In this case, the second fastening portion 142 may be formed on the side plate 120 opposite to the side on which the first fastening portion 141 is formed.

[0051] For example, if the first fastening portion 141 is formed on the first side panel 121, the second fastening portion 142 can be formed on the third side panel 123. Also, if the second fastening portion 142 is formed on the first side panel 121, the first fastening portion 141 can be formed on the third side panel 123. Similarly, the first fastening portion 141 and the second fastening portion 142 can be selectively adopted and provided on the second side panel 122 and the fourth side panel 124. In this way, adjacent unit-type solar modules 1 can be continuously coupled together by the first fastening portion 141 and the second fastening portion 142 that are coupled to each other.

[0052] The first fastening portion 141 or the second fastening portion 142 may include a fixing portion 144 so as to be fixed to the wall surface 10 of the building by a fastening member 150. The structure fixed by the fastening member 150 and the fixing portion 144 will be described again later.

[0053] 3, the coupling part 140 may be provided to be located below the power generation part 200. That is, the first and second fastening parts 141 and 142 may be formed by extending from the end of the side plate 120 formed by bending from the base plate 110.

[0054] More specifically, the first fastening portions 141 may be formed on the third side panel 123 and the fourth side panel 124 as shown in the drawings. The first fastening portions 141 may be formed by being bent so as to protrude radially outward from the third and fourth side panels 123 and 124. The first fastening portions 141 may be formed by being bent at a 90-degree angle for stable connection with the adjacent unit-type solar module 1.

[0055] As shown in the drawings, the second fastening portion 142 may be formed on the first side panel 121 and the second side panel 122. The second fastening portion 142 may be bent to form a fastening groove 143 so that the first fastening portion 141 can be inserted and coupled thereto. That is, the second fastening portion 142 may be bent multiple times to form the fastening groove 142 on the radially inner side, and the end portion may be formed to protrude radially outward. In this case, it will be apparent that the position where the fastening groove 142 is formed and the position where the first fastening portion 141 is formed are located on the same line.

[0056] Such a pair of fastening portions 141, 142 not only serves to connect adjacent unit-type solar modules 1, but also serves as a fixing portion 144 for fixing to the wall surface 10 of a building. For example, the second fastening portion 142 may be provided with a fixing portion 144 formed by extending from an end portion of the second fastening portion 142.

[0057] The fixing portion 144 is provided so as to be in surface contact with the wall surface 10, and may include a fastening hole 145 formed so as to be fixed to the wall surface 10 via a fastening member 150. The fastening member 150 may be a commonly used fixing part such as a bolt, nail, screw, or machine screw.

[0058] The power generating unit 200 may be attached to the front surface of the support unit 100 and configured to generate electricity using sunlight. The power generating unit 200 may include a plurality of solar cells 210, a film layer 220 configured 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.

[0059] The solar cell 210 generates direct current by absorbing the energy of incident sunlight through the photoelectric effect, and can be manufactured by joining a P (positive) type semiconductor and an N (negative) type semiconductor. This solar cell 210 generates holes (+) and electrons (-) using the energy of sunlight, with the holes gathering on the P-type semiconductor side and the electrons gathering on the N-type semiconductor side, generating a potential difference and supplying current to the outside.

[0060] The solar cells 210 may be repeatedly arranged at regular intervals, for example, in a lattice pattern, and may be made of either crystalline silicon (monocrystalline silicon, polycrystalline silicon) or amorphous silicon. Although four solar cells 210 are shown in one unit-type solar module 1, the number, shape, and type of the solar cells 210 may be changed depending on the size of the module.

[0061] The film layer 220 may be provided to cover the upper and lower surfaces of the solar cell 210. That is, the film layer 220 may include an upper film layer 221 that covers the upper surface of the solar cell 210 and a lower film layer 222 that covers the lower surface of the solar cell 210. The film layer 220 may be made of an EVA (ethylene-vinyl acetate) copolymer. The film layer 220 protects the solar cell 210 from external foreign objects and enhances the durability of the solar cell 210.

[0062] In addition, when the power generating unit 200 is attached to the front surface of the support 100, the upper film layer 221 and the lower film layer 222 can be heated to form a single film layer 220 that encases the solar cells 210.

[0063] The cover window 230 is attached to the upper surface of the film layer 220 and serves to protect the solar cells 210. The cover window 230 may be provided to have a color. For example, the cover window 230 may be provided to have the same color as the support 100. By providing the cover window 230 to have a color, the solar cells 210 can be concealed so that they cannot be identified from the outside, and the cover window 230 can improve the aesthetic appeal of the building as a finishing material.

[0064] Additionally, the cover window 230 can be made from glass or a transparent polymer material.

[0065] The bus bar 240 is connected to the solar cells 210. The bus bar 240 is in direct contact with the top surface of the outermost solar cell 210 to be connected to the solar cell 240. The bus bar 240 may be connected to the junction box 400 via a conductor 244. The junction box 400 may be installed in the pocket portion 130, and the base plate 110 of the support 100 serves as a substrate for the solar cell 210, so that the conductor 244 can be connected to the junction box 400. The support 100 may have a through hole 114 through which the conductor 244 passes. Thus, the conductor 244 is connected to the junction box 400 through the through hole 114. In this case, an insulator 134 may be installed to cover the edge of the through hole 114 to prevent the conductor 244 from being connected to the support 100.

[0066] Meanwhile, the support unit 100 may be provided with first and second connectors 410, 420 so that + / - DC electricity can be connected separately when the junction box 400 is installed in the pocket unit 130 and connected to an adjacent unit-type solar module 1. For example, the first connector 410 may be connected to the junction box 400 via a cable 430 so as to be connected to positive (+) DC electricity, and the second connector 420 may be connected to the junction box 400 via a cable 430 so as to be connected to negative (-) DC electricity.

[0067] When the first connector 410 is assembled with an adjacent unit type solar module 1, it can be connected to the second connector 420, and the second connector 420 can be connected to the first connector 410. Therefore, the first connector 410 and the second connector 420 can be installed with a portion exposed to the outside from the support part 100. That is, a connection hole 125 in which the connectors 410, 420 are installed can be formed in the portion of the side panel 120 of the support part 100 where the first and second connectors 410, 420 are installed.

[0068] The insulating section 300 can be formed by filling the pocket section 130 with a filler material. The insulating section 300 includes insulating materials generally used in buildings, but can also be made of expanded polystyrene (EPS), polyurethane, and glass wool materials that can ensure quasi-noncombustible or higher performance.

[0069] As described above, the unit-type solar module 1 according to the present invention is provided as a single unit and can be selectively assembled from all four sides, and therefore can be used as an exterior material for buildings and can also function as a heat insulating material.

[0070] Meanwhile, the unit type solar module 1 has been illustrated and described as having the power generation unit 200 attached to the front surface of the base plate 110 of the support unit 100, but for process convenience, aesthetics, and stability, the power generation unit 200 may be attached by being seated on the support unit 100. Such a unit type solar module 1 is shown in FIG.

[0071] 7 is a cross-sectional view showing a modified example of a support provided in a unit-type solar module according to one embodiment of the present invention, in which the same reference numerals as those in the previous drawings refer to members that perform the same functions.

[0072] 7, the unit type solar module 1 according to this embodiment may further include a seating groove 112 recessed inward from the front surface of the base plate 110 of the support part 100. That is, the power generation part 200 may be inserted into the seating groove 112 to be mounted. In this case, the thickness of the power generation part 200 and the depth of the seating groove 112 may be set to correspond to each other. As a result, the surface of the power generation part 200 and the surface of the support part 100 may be positioned on the same line.

[0073] Meanwhile, the unit type solar modules 1 have been illustrated and described as being assembled horizontally when connecting adjacent unit type solar modules 1, but this is not limited thereto and they can also be assembled vertically. The structure of such a unit type solar module 1 is shown in Figures 8 and 9.

[0074] Fig. 8 is a cross-sectional view showing a modified example of a coupling part provided in a unit type solar module according to one embodiment of the present invention, and Fig. 9 is a view showing the assembly state of an adjacent unit type solar module via the coupling part according to Fig. 8. Here, the same reference numerals as in the previous drawings refer to components that perform the same functions.

[0075] According to this embodiment, the unit type solar module 1 can be provided with a coupling portion so that the unit type solar module 1 can be coupled to an adjacent unit type solar module 1 in the vertical direction.

[0076] The coupling part 140' includes a pair of fastening parts 141' and 142', and the pair of fastening parts 141' and 142' may be composed of a first fastening part 141' and a second fastening part 142'. In this case, the coupling part 140' according to this embodiment may be provided to be located above the power generation part 200, unlike the previous embodiment.

[0077] More specifically, the first fastening portion 141' is formed to extend upward from the side plate 120 of the support portion 100, and may be formed by bending the extended portion so as to be inclined.

[0078] The second fastening portion 142' may be formed to extend upward from the side panel 120 and 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 formed to extend upward from the side panel 120 and bent multiple times to allow the first fastening portion 141' to be inserted. In this case, the second fastening portion 142' may be provided with an inclined locking portion, so that when the first fastening portion 141' is coupled to the second fastening portion 142', the inclined portion of the first fastening portion 141' may engage with the locking portion to prevent separation.

[0079] That is, the unit type solar modules 1 can be assembled by being continuously connected in the vertical direction via the pair of fastening portions 141', 142' as described above.

[0080] The fastening parts 141' and 142' may not only serve to couple adjacent unit type solar modules 1 together but also serve as fixing parts 144' to be fixed to the wall surface 10 of the building. For example, the fastening parts 141' and 142' may include fixing parts 144' that are coupled to the first fastening part 141' and fixed to the wall surface 10.

[0081] The fixing portion 144' may be coupled to the first fastening portion 141' and provided to be 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 via a fastening member 150. The fastening member 150 may be a commonly used fixing part such as a bolt, nail, screw, or the like.

[0082] Meanwhile, the unit type solar module 1 according to this embodiment can be provided, as in the previous embodiment, so that the power generation unit 200 is seated on and attached to the front surface of the base plate 110 of the support unit 100. Such a unit type solar module 1 is shown in FIG.

[0083] Figure 10 is a cross-sectional view showing a modified example of a support part provided in the unit-type solar module shown in Figure 8. Here, the same reference numerals as in the previous drawings refer to members that perform the same functions.

[0084] 10, the unit type solar module 1 according to this embodiment may further include a seating groove 112 recessed inward from the front surface of the base plate 110 of the support part 100. That is, the power generation part 200 can be inserted into the seating groove 112 to be mounted. In this case, the thickness of the power generation part 200 and the depth of the seating groove 112 may be set to have a corresponding length. As a result, the surface of the power generation part 200 and the surface of the support part 100 may be positioned on the same line.

[0085] In this way, the unit type solar module 1 including various modified examples can be continuously connected to adjacent unit type solar modules 1 vertically or horizontally to be used as an exterior material of a building, and thermal insulation performance can be ensured through the thermal insulation material installed inside.

[0086] Furthermore, by installing the power generating unit 200 in the seating groove 112 of the support unit 100, it is possible to improve aesthetics and also to prevent the power generating unit 200 from being exposed to danger in the event of a fire.

[0087] As described above, the present invention has been described using limited embodiments and drawings, but the present invention is not limited thereto, and it goes without saying that various modifications and variations can be made by a person having ordinary skill in the art to which the present invention pertains within the technical spirit of the present invention and the equivalent scope of the claims set forth below.
