Description

3D foldable solar module

[0001] The present invention relates to a three-dimensional foldable solar module.

[0002] In particular, the present invention relates to a three-dimensional foldable solar module capable of generating solar power at a desired location without spatial constraints.

[0003] Solar power generation, which generates energy using sunlight, is gaining attention as a renewable energy source amid growing concerns about environmental issues. Consequently, each country is seeking to transform its current energy production systems to eco-friendly energy sources.

[0004] However, solar power generation systems have unresolved problems: first, they require a large area, and second, they must be exposed to the outside.

[0005] It's true that producing energy using solar energy is less efficient than conventional energy production methods. Therefore, to produce usable energy, a large number of panels are required, and these panels must be positioned in parallel over a large area. Consequently, solar power systems are being installed in areas with low population density, outside of urban areas.

[0006] Additionally, solar power generation requires exposure to light, requiring the panels to be exposed to the sky. Therefore, solar power generation presents significant installation limitations.

[0007] These two major problems hinder the practical application of solar power systems. Consequently, solar power systems remain stuck in the phase in which they were first invented.

[0008] The present invention aims to address the aforementioned issues and provide a highly versatile, three-dimensional foldable solar module. For example, the present invention aims to provide a three-dimensional foldable solar module capable of generating solar power anywhere, without spatial constraints.

[0009] A three-dimensional foldable solar module according to one embodiment may include a frame portion in which an installation space is formed and a solar power generation portion arranged in a form that closes the installation space and generates energy using sunlight supplied through the installation space.

[0010] The above frame portion may be characterized in that it is formed by connecting support portions arranged in a horizontal or vertical direction.

[0011] The above-mentioned support members may be characterized in that two or more are arranged in a vertical direction to form an installation space therebetween, and the solar power generation unit is arranged in the installation space and connected to the support members.

[0012] The above-mentioned support members are arranged in groups of four spaced apart from each other, and the solar power generation unit may be arranged to contact at least two of the four support members and close the installation space.

[0013] It may be characterized in that a folding part is formed on one side of the above support part, into which the support part is folded.

[0014] The above folding portion may be characterized in that it is formed in a symmetrical shape at a position symmetrical to each support portion.

[0015] The above solar power generation unit may include a plate on which a circuit is drawn and particles arranged on the plate that generate energy when exposed to sunlight.

[0016] The above plate may be fixed to the support and may be characterized by being connected to the support through a movable connection that can be slidably moved.

[0017] The above movable connecting member may include a first fixing member that surrounds the support member and a second fixing member that surrounds the support member at a position symmetrical to the first fixing member, and the first fixing member and the second fixing member may be characterized in that they are able to slide by approaching or moving away from one side and being fixed to or detached from the support member.

[0018] The interior of the above support may be characterized by the formation of a space.

[0019] The above frame portion may be characterized in that a reflector that reflects sunlight is arranged therein.

[0020] The above solar power generation unit may be characterized in that a folding unit is arranged so that the solar power generation unit can be folded.

[0021] The above three-dimensional foldable solar module may include an incident portion, wherein the solar power generation portion is spaced apart from each other, and the incident portion is positioned in a manner that permanently closes the spaced-apart space of the solar power generation portion.

[0022] It may be characterized in that a folding part is arranged at a position where the above solar power generation part and the above incident part come into contact.

[0023] The above support member may be arranged along at least one of a horizontal or vertical direction to form a line of a shape of a set shape, and the solar power generation member may be arranged on a surface of the shape of the set shape.

[0024] According to one embodiment of the present invention, a highly versatile three-dimensional foldable solar module can be provided. For example, the present invention can be placed in a location desired by the user, rather than in a specific location, such as a rooftop shelf during a camping trip, or adjacent to an indoor window, to generate solar power.

[0037] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0038] The terminology used herein is merely used to describe specific embodiments and is not intended to limit the present invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In the present invention, it should be understood that the terms "comprise" or "have" are intended to specify the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, but do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0039] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Please note that, where possible, identical components are represented by identical reference numerals throughout the drawings. Furthermore, detailed descriptions of well-known functions and configurations that may obscure the gist of the present invention will be omitted. For the same reason, some components in the attached drawings are exaggerated, omitted, or schematically depicted.

[0040] A three-dimensional foldable solar module according to one embodiment of the present invention can be installed without spatial restrictions. This is possible due to the solar power generation unit of the present invention. Therefore, let's first examine the solar power generation unit according to one embodiment of the present invention.

[0041] Figure 1 illustrates a solar power generation unit in a three-dimensional foldable solar module according to one embodiment of the present invention.

[0042] The present invention is formed in a shape in which a solar power generation unit (200) is arranged on a plate (210) as shown in FIG. 1, with particles (220). Here, the particles (220) may be spherical particles (220) that cannot be seen with the naked eye as shown in FIG. 1. (Naturally, the cross-section is circular.) Therefore, sunlight irradiated toward the solar power generation unit (200) can penetrate the plate (210). Accordingly, the present invention can perform solar power generation even when the solar power generation unit (200) is arranged in a laminated shape.

[0043] According to one embodiment, the solar power generation unit (200) of the present invention may be composed of a plate (210) and particles (220).

[0044] The plate (210) can be manufactured from a flexible material and formed into a specific shape. The plate (210) can be transparent or opaque. However, it is preferable that the plate (210) be composed of a material or materials that allow sunlight to pass through.

[0045] A circuit diagram may be printed on the plate (210). The circuit diagram may be printed on one side of the plate (210) and connected in series or parallel. (Fig. 1 illustrates a serial circuit diagram drawn on the plate (210).)

[0046] The particle (220) may include a first electrode layer (221), a second electrode layer (222), a passivation layer (223), a prevention layer (224), a first connection portion (225), and a second connection portion (226).

[0047] The particle (220) is formed in a spherical shape with the bottom exposed. That is, the particle (220) can be formed in a spherical shape by connecting other components. The second electrode layer (222) can be arranged in a shape in which the first electrode layer (221) is arranged inside. The first electrode layer (221) and the second electrode layer (222) can be formed in a shape in which the bottom is cut horizontally. In addition, the second electrode layer (222) can be arranged in a shape in which the first electrode layer (221) is arranged inside. The first electrode layer (221) and the second electrode layer (222) can be different types of silicon.

[0048] For example, the first electrode layer (221) may be N-type silicon, and the second electrode layer (222) may be P-type silicon. Therefore, when sunlight reaches the particle (220), energy can be generated by the movement of electrons and holes.

[0049] Here, if the first electrode layer (221) is N-type silicon and the second electrode layer (222) is P-type silicon, electrons and holes are gathered at the first connection portion (225) connected to the lower side of the first electrode layer (221) and the second connection portion (226) arranged at the lower side of the second electrode layer (222), respectively, and thereby electricity can flow through the circuit diagram of the plate (210).

[0050] Here, a passivation layer (223) may be placed on the outer side of the first electrode layer (221) to ensure smooth transmission of electrons and holes. In addition, a prevention layer (224) may be placed to surround the passivation layer (223) to prevent reflection of sunlight.

[0051] In this way, the present invention enables particles (220) that cannot be seen with the naked eye to produce energy. The energy (electrical energy) generated by each of these particles (220) may be very small, but when the energy generated is combined, it can produce a very large amount of energy compared to the cells of previous solar power generation systems.

[0052] In addition, since the present invention has a circuit diagram printed on a plate (210) and particles (220) placed on the upper side of the circuit diagram, the circuit diagram can be formed in various shapes and the spacing between particles (220) can also be adjusted.

[0053] And, a first connecting portion (225) and a second connecting portion (226) may be arranged on the particle (220). The first connecting portion (225) may be connected to the first electrode layer (221), and the second connecting portion (226) may be connected to the second electrode layer (222). Here, the first connecting portion (225) may be a + electrode or a - electrode depending on the types of the first electrode layer (221) and the second electrode layer (222), and the second connecting portion (226) may be an opposite electrode.

[0054] In this way, the solar power generation unit (200) of the present invention has the characteristics of having small particles (220), thus forming a space between the particles (220) and thus being permeable, and having very high usability due to the flexible plate (210).

[0055] FIG. 2 illustrates a three-dimensional foldable solar module according to a first embodiment of the present invention.

[0056] According to the first embodiment, the three-dimensional foldable solar module of the present invention may include a frame portion (100) and a solar power generation portion (200).

[0057] The frame (100) may refer to a skeleton on which the solar power generation unit (200) is placed. The frame (100) may include a support (110). The support (110) may be composed of at least two. The support (110) may be placed spaced apart from each other. Therefore, an installation space (120) may be formed in the support (110). The installation space (120) refers to a space formed by the support (110). Since the first embodiment includes two support (110), the space between the support (110) may become the installation space (120).

[0058] The solar power generation unit (200) is arranged in a manner that closes the installation space (120). For example, the solar power generation unit (200) may be arranged along the longitudinal direction of the support unit (110) as illustrated in FIG. 2. Here, the solar power generation unit (200) is formed in a structure as described with reference to FIG. 1. Therefore, when the solar power generation units (200) are arranged along the longitudinal direction, all of the solar power generation units (200) can generate energy.

[0059] That is, when sunlight is irradiated from the top to the bottom, the solar power generation unit (200) that is irradiated with sunlight first generates energy using the sunlight. At this time, due to the transparency of the plate (210), the space between the particles (220), etc., the sunlight is transmitted and can be irradiated to the next positioned solar power generation unit (200). Therefore, although not shown in FIG. 2, the present invention can arrange the solar power generation units (200) in a laminated structure, thereby generating highly efficient energy in a small space.

[0060] FIG. 3 illustrates a three-dimensional foldable solar module according to a second embodiment of the present invention.

[0061] According to the second embodiment, a three-dimensional foldable solar module may include a frame portion (100) and a solar power generation portion (200).

[0062] The frame (100) may include three support members (110). Here, the three support members (110) may be formed to be positioned near the corners of a triangle. Therefore, some portion of the installation space (120) may have a triangular shape. That is, the support members (110) may be positioned to form a line of a shape of a specific shape. Therefore, the surface of the shape of a specific shape may be formed as the installation space (120) by the support members (110).

[0063] Additionally, the installation space (120) may include a first installation space (121) and a second installation space (122).

[0064] The first installation space (121) may refer to a space formed between the support members (110). Therefore, it may be formed in a triangular shape.

[0065] The second installation space (122) may refer to the space on the side between the two support members (110). Therefore, the second installation space (122) may be a space having a rectangular shape with the upper and lower sides open.

[0066] The plate (210) of the solar power generation unit (200) can be formed corresponding to the first installation space (121) and the second installation space (122). Accordingly, the solar power generation unit (200) can be stably supported. In addition, since the solar power generation unit (200) is similar to that described in FIG. 1, it can transmit sunlight. Accordingly, the present invention can generate energy by efficiently utilizing space. In other words, even if the solar power generation unit (200) is arranged in a vertical direction, unlike the conventional method, solar power generation can be performed.

[0067] Meanwhile, the solar power generation unit (200) can be connected through the support unit (110) and the movable connection unit (130).

[0068] The movable connection part (130) is positioned between the support part (110) and the solar power generation part (200) to firmly connect the solar power generation part (200) to the support part (110), or may be loosely connected so that the solar power generation part (200) can slide and move relative to the support part (110). The movable connection part (130) may include a first fixing member (131) and a second fixing member (132).

[0069] The first fixing member (131) and the second fixing member (132) may each be formed in a semicircular shape. Therefore, the first fixing member (131) and the second fixing member (132) may each be formed in a shape that surrounds the periphery of the support member (110). Some of the first fixing member (131) and the second fixing member (132) may overlap each other. In addition, other parts of the first fixing member (131) and the second fixing member (132) may be hinge-connected to each other.

[0070] For example, the first fixing member (131) is formed with a protruding portion, and the second fixing member (132) is formed with a groove in which the protruding portion of the first fixing member (131) is placed. Therefore, the first fixing member (131) is formed with a portion that overlaps the second fixing member (132). Depending on the length (depth) of this overlapping portion, the movable connection member (130) can be firmly or loosely connected to the support member (110).

[0071] That is, when the overlapping areas of the first fixing member (131) and the second fixing member (132) are in large contact and fixed, the first fixing member (131) and the second fixing member (132) strongly press the support member (110), so that the solar power generation unit (200) does not slide and is fixed to the support member (110). Otherwise, the first fixing member (131) and the second fixing member can slide the support member (110), so that the solar power generation unit (200) can slide.

[0072] In addition, the protruding portions and grooves of the first fixing member (131) and the second fixing member (132) may be fixed in any manner without a problem. For example, the protruding portion of the first fixing member (131) may have a recess formed on the outside, and the groove of the second fixing member (132) may have a protruding portion formed therein so that the recess and the protruding portion are joined (protruding and recessed structure). Alternatively, the protruding portion of the first fixing member (131) may be a buckle, and the groove of the second fixing member (132) may be a portion that receives the buckle. In other words, as long as the degree to which the first fixing member (131) and the second fixing member (132) are fixed to the support member (110) differs depending on the degree of overlapping of the protruding portions and the grooves, the structure will not be a major problem.

[0073] Meanwhile, the solar power generation unit (200) can be fixed to the support unit (110) via a fixing unit (instruction number). The fixing unit is a solar power generation unit (200) placed in a second installation space (121) that does not require sliding movement, that is, the fixing unit connects and fixes the solar power generation unit (200) placed on the side with reference to FIG. 3 and the support unit (110).

[0074] FIG. 4 illustrates a three-dimensional foldable solar module according to a third embodiment of the present invention.

[0075] FIG. 5 sequentially illustrates the folding process of a three-dimensional foldable solar module according to a third embodiment of the present invention.

[0076] Hereinafter, the solar power generation unit (200) will be indicated by diagonal lines and dotted lines. This is to enable the solar power generation unit (200) to be identified and distinguished. It should be noted that the solar power generation unit (200) is no different and is the solar power generation unit (200) described in FIG. 1.

[0077] According to the third embodiment, the three-dimensional foldable solar module includes a frame portion (including 110 and 120), a solar power generation portion (200), and a reflector portion (300).

[0078] The frame portion (100) may include four support portions (110). The support portions (110) may be positioned at portions corresponding to the corners of a square.

[0079] The support member (110) forms a skeleton, and an installation space (120) can be formed between the support members (110).

[0080] Here, the installation space (120) may mean between four support members (110) or between two support members (110). Therefore, the installation space (120) may include a first installation space (121) and a second installation space (122).

[0081] Additionally, a folding portion (140) may be formed on the support portion (110). The role of the folding portion (140) is similar to that described with reference to FIG. 3. Therefore, the support portion (110) may be folded based on the folding portion (140). However, it is preferable that the folding portion (140) be formed at a symmetrical position.

[0082] That is, as illustrated in Fig. 4, the folding part (140) can be connected in a form that connects two support parts (110), and the folding part (140) can be connected in a form that connects the remaining two support parts (110) that are not connected. Therefore, the present invention can be folded in a symmetrical form.

[0083] Meanwhile, as shown in (b) of FIG. 5, the portion where the folding portion (140) is formed is folded, and the portion where it is not formed is fixed, so that when the folding portion (140) is operated and folded, the distance between the folding portions (140) can be moved so as to become closer. Therefore, it is preferable that the folding portion (140) be formed in a symmetrical shape.

[0084] That is, one of the two folding parts (140) is formed to have a semicircular cross-section, and the other is formed to have a semicircular cross-section of a different shape. Therefore, when the folding part (140) is operated and the support part (110) is completely folded, each folding part (140) is formed to have a circular cross-section by contacting each other.

[0085] The solar power generation unit (200) is placed in an installation space (120) (a first installation space (121), a second installation space (122)). Here, it is preferable that the solar power generation unit (200) be placed in the first installation space (121), which is an installation space (120) formed between four support members (110), and the second installation space (122) formed between any two support members (110).

[0086] Therefore, the solar power generation unit (200) is arranged along the length direction of the support unit (110) so that it can receive sunlight in a vertical direction, or it can receive sunlight from the side.

[0087] Here, the solar power generation unit (200) placed by closing the first installation space (121) can be connected to the support unit (110) through the movable connection unit (130). The movable connection unit (130) can include the first fixing unit (131) and the second fixing unit (132) as described with reference to FIG. 3. Accordingly, the solar power generation unit (200) can be fixed to the support unit (110) or moved by sliding.

[0088] Meanwhile, the solar power generation unit (200) placed in the second installation space (122) can be fixed to the support unit (110) via a fixing unit (no instruction number). Unlike the movable connection unit (130), the fixing unit can stably fix the solar power generation unit (200) to the support unit (110).

[0089] Meanwhile, the guide part (150) and the moving connection part (130) can be connected.

[0090] The guide part (150) can be fixed to the support part (110) on one side and connected to the movable connection part (130) on the other side. The guide part (150) can be folded based on the center part, similar to the folding part (140). Therefore, the guide part (150) can allow the movable connection part (130) to move based on the support part (110) only to the extent of the length of the guide part (150).

[0091] In addition, the guide part (150) can assist the movement of the movable connection part (130). Therefore, the solar power generation part (200) can only be moved to a position set based on the support part (110), and at the same time, when the movable connection part (130) loosely fixes the support part (110), the support part (110) can be moved in a straight line.

[0092] Meanwhile, a reflector (300) may be placed on the lower side of the frame (100) (lower side of the support (110). The reflector (300) reflects sunlight when it is irradiated. Therefore, the reflector (300) can increase the efficiency of solar power generation. That is, the reflector (300) can improve the efficiency of solar power generation by reflecting sunlight that has passed through the solar power generation unit (200) and moving it back to the solar power generation unit (200).

[0093] Meanwhile, an incident portion (400) may be placed on the upper side of the frame portion (100) (on the upper side of the support portion (110)). The incident portion (400) may be a plate onto which sunlight is incident. Here, the incident portion (400) may be the solar power generation portion (200) itself, or may be a flat, solid plate (210) through which sunlight can pass.

[0094] These three-dimensional foldable solar modules can be folded as shown in Fig. 5.

[0095] First, as can be seen in (a) of Fig. 5, the overlapping portion of the first fixing member (131) and the second fixing member (132) of the movable connecting member (130) is shortened to secure the mobility of the movable connecting member (130).

[0096] Afterwards, as can be seen in (b) of Fig. 5, the movable connecting part (130) is moved so that the solar power generation part (200) is moved adjacent to the reflecting part (300) and the incident part (400). At this time, the guide part (150) can be folded.

[0097] As can be seen in (c) of Fig. 5, the folding member (140) can be folded based on the folding member. Then, the present invention can be changed from a large-volume hexahedron to a small-volume hexahedron. At this time, the folding member (140) can be in contact with both sides.

[0098] If the folded 3D foldable solar module of the present invention is to be transformed into its original shape, it may be possible to do so by performing (a), (b), and (c) of Fig. 5 in reverse order.

[0099] FIG. 6 illustrates a three-dimensional foldable solar module according to a fourth embodiment of the present invention.

[0100] According to the fourth embodiment, a three-dimensional foldable solar module may be provided with a battery (500). That is, as illustrated in FIG. 6, a support plate (210) may be fixed to the support member (110) at a distance from the lower side of the reflector (300). Furthermore, a battery (500) may be provided between the reflector (300) and the support plate (210). Therefore, energy generated by the solar power generation unit (200) may be transmitted to and charged by the battery (500).

[0101] Meanwhile, although not shown, the three-dimensional foldable solar module according to the above-described embodiment, including the fourth embodiment, can be connected to various devices to enable the devices to operate.

[0102] For example, the aforementioned three-dimensional foldable solar module can be connected to lighting (including various types of lighting, including LED lighting). Therefore, when the three-dimensional foldable solar module generates solar power, the lighting can be powered.

[0103] For example, the aforementioned 3D foldable solar module can be connected to an inverter. Therefore, when the 3D foldable solar module generates solar power, the direct current can be converted to alternating current by the inverter. This converted current can then be connected to various devices.

[0104] For example, the aforementioned three-dimensional foldable solar module can be connected to an air conditioner. Therefore, when the three-dimensional foldable solar module generates solar power, the air conditioner can operate and supply cool air.

[0105] Additionally, multiple 3D foldable solar modules can be provided and connected to different devices. Furthermore, these different devices can be operated through a single interface. For example, the present invention can operate various devices, such as lighting, inverters, and air conditioners, using a terminal with a single interface.

[0106] In addition, the device can be placed in the space formed by the frame (100) and the solar power generation unit (200). For example, the frame (100) may form a rectangular parallelepiped, and the solar power generation unit (200) may be placed on a surface of the rectangular parallelepiped. The devices can be positioned inside the rectangular parallelepiped. That is, four support units (110) may be placed vertically and spaced apart from each other, and four may be placed horizontally and spaced apart from each other. The solar power generation unit (200) may be placed in a form that closes the surface, and the devices can be placed within the space.

[0107] Fig. 7 illustrates a cross-section of a support according to an embodiment of the present invention.

[0108] The support member (110) of the present invention may have a space (111) formed therein. This space (111) may be a line space (111) where a line through which electric energy is transferred is positioned. The line space (111) may be formed so as to be mutually connected when the support members (110) come into contact with each other.

[0109] Alternatively, it may be formed to be in communication with the aforementioned movable connection part (130, see FIG. 4). Therefore, a line through which energy (electrical energy) generated from the solar power generation part (200) can be moved may be arranged. Accordingly, the present invention can be arranged in various locations so that energy generated using solar energy can be transmitted to the battery (500). The support part (110) described through FIG. 6 may be the support part (110) of the three-dimensional foldable solar module according to the aforementioned first to fourth embodiments.

[0110] Figure 8 illustrates a cross-section of a support according to another embodiment of the present invention.

[0111] In another embodiment, the support member (110) may have a line space (111) formed therein as described above, but the line space (111) inside may be divided into a first line space (111a) and a second line space (111b).

[0112] The interior of the support member (110) may be divided into a first line space (111a) and a second line space (111b) by a partition wall (112). Accordingly, the positive and negative lines may not touch each other and may be arranged separately. A communication hole (113) may be formed in the partition wall (112). Therefore, the first line space (111a) and the second line space (111b) may be connected through the communication hole (113). Accordingly, the support member (110) according to another embodiment may be easy to organize the lines.

[0113] FIG. 9 illustrates a three-dimensional foldable solar module according to a fifth embodiment of the present invention.

[0114] A three-dimensional foldable solar module according to the fifth embodiment is an improvement of the three-dimensional foldable solar module according to the first embodiment, and includes a frame portion (100) and a solar power generation portion (200). The frame portion (100) includes a support portion (110) and an installation space (120) similar to the three-dimensional foldable solar module according to the first embodiment.

[0115] A folding section (140) may be placed at the center of the solar power generation unit (200). The folding section (140) may allow the solar power generation unit (200) to be folded based on the folding section (140). Therefore, the solar power generation unit (200) may be folded and placed based on the folding section (140) as needed.

[0116] Meanwhile, although FIG. 9 illustrates that one folding part (140) is arranged on the solar power generation unit (200), this is not limited thereto, and multiple folding parts (140) may be arranged. That is, the folding parts (140) may be arranged in various ways, such as two, three, or four, and accordingly, the solar power generation unit (200) may be folded into various shapes. For example, the solar power generation unit (200) may be arranged to have a cross-section such as 'V' or 'W' due to the multiple folding parts (140).

[0117] Therefore, the present invention can generate more energy per space because the solar power generation unit (200) is folded and arranged based on the folding unit (140).

[0118] FIG. 10 illustrates a three-dimensional foldable solar module according to a sixth embodiment of the present invention, FIG. 11 illustrates a three-dimensional foldable solar module according to a seventh embodiment of the present invention, and FIG. 12 is an example of arranging the three-dimensional foldable solar modules of FIGS. 10 and 11.

[0119] The three-dimensional foldable solar module according to the sixth and seventh embodiments illustrated in FIGS. 10 and 11 is a modified embodiment of the third embodiment, in which a folding part can be arranged in the solar power generation part (200) as in FIG. 9.

[0120] The sixth and seventh embodiments may include a solar power generation unit (200), an incident unit (400), and a folding unit (140). That is, a folding unit (140) may be placed on the solar power generation unit (200), a folding unit (140) may be placed on the incident unit (400), and then a folding unit (140) may be placed between the solar power generation unit (200) and the incident unit (400).

[0121] Depending on their arrangement, a three-dimensional foldable solar module can be formed as shown in FIGS. 10 and 11. That is, as shown in FIG. 10, the solar power generation units (200) can be spaced apart and arranged in the vertical direction based on the drawing, and the incident unit (400) can be arranged on the side. Alternatively, this can be rotated clockwise so that the incident unit (400) is arranged on the upper side.

[0122] And these three-dimensional foldable solar modules can be arranged in an overlapping manner as shown in Fig. 12. That is, another three-dimensional foldable solar module can be arranged on top of another three-dimensional foldable solar module.

[0123] Alternatively, although not shown, the three-dimensional foldable solar modules can be arranged in close contact with each other in the horizontal direction. Alternatively, although not shown, the three-dimensional foldable solar modules can be arranged in various shapes, such as a cube, by overlapping or closely arranging them. In this way, the present invention can maximize energy generation efficiency by arranging the three-dimensional foldable solar modules in a limited space due to the characteristics of the solar power generation unit (200). In addition, unlike the conventional method, it can be arranged without being restricted by location.

[0124] Meanwhile, although not shown, the three-dimensional foldable solar modules according to the fifth, sixth, and seventh embodiments can be connected to and arranged in various devices as described above.

[0125] And the three-dimensional foldable solar modules according to the fifth, sixth, and seventh embodiments can be operated with the same interface. For example, the three-dimensional foldable solar modules according to the fifth, sixth, and seventh embodiments can be operated as connected devices using a terminal having a single interface.

[0126] Above, one embodiment of the present invention has been described, but a person having ordinary skill in the art will be able to modify and change the present invention in various ways by adding, changing, deleting or adding components, etc., within the scope that does not depart from the spirit of the present invention described in the claims, and this will also be considered to be included within the scope of the rights of the present invention.
