Description

BIPV modules

[0001] The present invention relates to a BIPV module having convenience of construction by simplifying the installation structure of a solar module.

[0002] More specifically, the present invention relates to a BIPV module that can minimize deformation and efficiency reduction due to temperature changes by forming an insulation layer in the space between a roof and a solar module or between an exterior wall and a solar module, and can improve insulation and watertightness by minimizing the gap between adjacent solar modules.

[0003] BIPV modules are a system that can obtain solar energy by using solar modules as building materials (building exterior walls, roofs, windows, balconies, shading facilities, etc.).

[0004] As the demand for sustainable buildings, or green buildings, that optimize efficiency by using natural energy increases, building-integrated photovoltaic systems (BIPV) are increasingly being applied to recently constructed buildings.

[0005] This is an effective way to conserve the environment and save energy by using eco-friendly energy called solar energy.

[0006] Since the 2000s, with the increase in electricity demand and the international community's interest in renewable energy, the number of cases of building-integrated solar power generation systems being installed in the solar power field has been gradually increasing.

[0007] In the past, energy was collected through solar panels installed uniformly in separate spaces, as in the form of solar power generation, but recently, in order to minimize space constraints, a technology has been developed to install solar panels using building materials such as frames on the exterior of a building, so that it can be used not only as a building exterior material but also for solar power generation.

[0008] However, the conventional photovoltaic power generation system (BIPV) had problems with insulation because the solar modules were installed adjacent to the building's exterior wall. To solve this problem, a complex frame structure was adopted to install the solar modules away from the building's exterior wall. However, the complex structure made construction difficult and increased the difficulty of the work, which increased the probability of safety accidents for workers.

[0009] The present invention has been devised to solve the above problems, and the problem to be solved by the present invention is to provide a BIPV module that can minimize deformation and efficiency reduction due to temperature changes by forming an insulation layer in the space between a roof and a solar module or between an exterior wall and a solar module, and can improve insulation and watertightness by minimizing the gap between adjacent solar modules.

[0010] In addition, another problem to be solved in the present invention is to provide a BIPV module that can improve workability by minimizing structure installation and improve watertightness and airtightness by configuring the module frame that wraps the side of the solar module to be in close contact with the outer frame by tightening the bolts.

[0011] In addition, another problem to be solved by the present invention is to provide a BIPV module in which clamps are provided between solar modules spaced apart from each other at the top and bottom to seal and connect the solar modules, thereby inducing rainwater and the like to flow along the solar modules spaced apart from each other at the top and bottom and preventing them from flowing onto the roof or outer wall.

[0012] In addition, another problem to be solved by the present invention is to provide a BIPV module that can be applied to solar modules having various specifications regardless of the size or type of the solar module, by combining module frames to surround the four sides of the solar module and enabling strong combination by a joint between the module frames.

[0013] In order to solve the above-mentioned problem, the present invention provides a BIPV module that is configured to install a plurality of solar modules in a checkerboard pattern on the outside of a roof or a wall, the BIPV module including an outer frame that is installed on the outside of a roof or a wall and has a longitudinal length in the upper and lower directions between the plurality of solar modules; and a module frame that is connected to four sides of the solar modules and moves the solar modules toward the front by tightening bolts; wherein the module frame moves the solar modules toward the front so that the module frame is in close contact with the outer frame, thereby solving the technical problem.

[0014] The present invention has a remarkable effect of minimizing deformation and efficiency reduction due to temperature changes by forming an insulating layer in the space between a roof and a solar module or between an outer wall and a solar module, and minimizing the gap between adjacent solar modules to improve insulation and watertightness.

[0015] In addition, the present invention has a remarkable effect of minimizing the installation of a structure, thereby improving workability, and improving watertightness and airtightness by configuring the module frame that wraps around the side of a solar module to be in close contact with the outer frame due to bolt tightening.

[0016] In addition, the present invention has a remarkable effect of preventing rainwater and the like from flowing onto the roof or outer wall by providing a clamp between the solar modules spaced apart from each other and sealing and connecting the solar modules, thereby inducing the solar modules to flow along the solar modules spaced apart from each other.

[0017] In addition, the present invention has the advantage of being applicable to solar modules having various specifications regardless of the size or type of the solar module, since the module frames are combined to surround the four sides of the solar module and the module frames are firmly combined by the joints between the module frames.

[0060] First, before describing various embodiments of the present invention in detail with reference to the attached drawings, it should be noted that terms such as “front”, “back”, “left”, “right”, “up”, “down”, “up”, “down”, “horizontal”, “vertical”, “front”, “back”, “one side”, “the other side”, “inner side”, and “outer side”) of components described in the following detailed description or depicted in the drawings do not simply indicate or imply that they must have a specific direction, and the description of such directions is intended to facilitate the description of components with reference to the attached drawings.

[0061] The BIPV module according to the present invention relates to a BIPV module that forms an insulation layer in the space between a roof and a solar module or between an outer wall and a solar module (10) to minimize deformation and efficiency reduction due to temperature changes, and to improve insulation and watertightness by minimizing the gap between adjacent solar modules (10).

[0062] Hereinafter, a BIPV module according to the present invention will be described in detail with reference to the attached drawings.

[0063] Fig. 1 is a perspective view of a BIPV module according to the present invention, and Fig. 2 is an exploded perspective view of a BIPV module according to the present invention.

[0064] The BIPV module according to the present invention is installed on a roof or an outer wall, and a gap is formed between the roof and a plurality of solar modules (10) or between the outer wall and a plurality of solar modules (10), thereby minimizing deformation and efficiency reduction due to temperature changes.

[0065] The BIPV module according to the present invention is configured to include an outer frame (100) installed on a roof or an outer wall, a module frame (200) coupled to the four sides of a solar module (10), and a clamp (300) provided between a pair of solar modules (10) provided on the upper and lower sides to cover the space therebetween.

[0066] Figure 3 is a perspective view showing an outer frame of a BIPV module according to the present invention.

[0067] The outer frame (100) is provided to have a longitudinal length in the upper and lower directions between the plurality of solar modules (10) when a plurality of solar modules (10) are installed in a checkerboard pattern, and is configured to include a slide home (110).

[0068] That is, such an outer frame (100) is installed on a roof or an outer wall, and is provided to have a longitudinal length in the upper and lower directions between a pair of solar modules (10) arranged on the left and right among a plurality of solar modules (10) arranged in a checkerboard pattern.

[0069] Such an outer frame (100) may have a slide groove (110) formed inwardly on one or more selected sides of one or the other side.

[0070] Preferably, as shown in FIG. 3, a slide groove (110) may be formed on each side, and a space is provided through the slide groove (110) into which a module frame (200) coupled to the side of the solar module (10) is fitted, thereby allowing a plurality of solar modules (10) to be stably installed.

[0071] At this time, the outer frame (100) can be made of a metal material with excellent strength, such as aluminum or stainless steel.

[0072] Furthermore, the outer frame (100) can be installed directly on the roof or outer wall or installed by a separate bracket.

[0073] Accordingly, the solar module (10) fitted into the slide home (110) of the outer frame (100) is installed at a predetermined distance from the roof or outer wall.

[0074] Fig. 4 is a planar cross-sectional view showing another embodiment of an outer frame in a BIPV module according to the present invention.

[0075] Depending on the design conditions, the outer frame (100) may be configured with a detachable structure on the front side and the back side, as shown in FIG. 4.

[0076] This will be described in detail with reference to FIG. 4. Another embodiment of the outer frame (100) may be configured to include a rear frame (120) and a front frame (130).

[0077] The rear frame (120) is provided to have a longitudinal length in the upper and lower directions between the plurality of solar modules (10) when a plurality of solar modules (10) are installed in a checkerboard pattern, and is configured to include a rear protrusion (121) and an inner latch (122).

[0078] This rear frame (120) is installed on a roof or an outer wall, and is provided to have a longitudinal length in the upper and lower directions between a pair of solar modules (10) arranged on the left and right among a plurality of solar modules (10) arranged in a checkerboard pattern.

[0079] At this time, the rear frame (120) can be installed directly on the roof or outer wall or installed by a separate bracket.

[0080] Referring to Fig. 4, the rear protrusion (121) is formed in a form that protrudes outward from the front side of the rear frame (120), and is formed as a pair spaced apart from each other.

[0081] The inner latch (122) is formed by a pair of rear protrusions (121) protruding toward each other at the end of the rear protrusion (121).

[0082] This inner latch (122) is interlocked with the outer latch (132) of the tip projection (131) described later, thereby ensuring that the rear frame (120) and the tip frame (130) are firmly connected to each other.

[0083] The leading edge frame (130) is provided on the front side of the rear protrusion (121) and is combined with the rear protrusion (121), and is configured to include the leading edge protrusion (131) and an outer latch (132).

[0084] Referring to Fig. 4, the tip protrusion (131) is formed in a form that protrudes outward from the back surface of the tip frame (130), and is configured as a pair spaced apart from each other.

[0085] At this time, it is preferable that the gap between a pair of leading protrusions (131) be formed narrower than the gap between a pair of rear protrusions (121).

[0086] Accordingly, in the process of combining the rear frame (120) and the front frame (130), a pair of front end protrusions (131) are inserted into the space between the pair of rear frames (120), and then the outer catch (132) and the inner catch (122) described later are interlocked with each other.

[0087] The outer latch (132) is formed to protrude outward at the end of the tip protrusion (131).

[0088] This outer latch (132) is interlocked with the inner latch (122) of the rear protrusion (121), thereby ensuring that the rear frame (120) and the front frame (130) are firmly connected to each other.

[0089] Depending on the design conditions, the rear frame (120) and the front frame (130) can be connected by bolt fastening.

[0090] For example, by fastening a bolt from the outside of the front frame (130) toward the rear frame (120), the rear frame (120) and the front frame (130) can be configured to be firmly connected.

[0091] Meanwhile, in the attached Fig. 4, an example is shown in which an inner latch (122) in an extended form that is bent inward is formed in the rear protrusion (121), and an outer latch (132) in an extended form that is bent outward is formed in the front protrusion (131). However, depending on the design conditions, it is obvious that an outer latch (132) may be formed in the rear protrusion (121) and an inner latch (122) may be formed in the front protrusion (131).

[0092] That is, the gap between a pair of leading protrusions (131) is configured to be wider than the gap between a pair of rear protrusions (121), so that when a pair of trailing protrusions (121) is inserted between a pair of leading protrusions (131), the outer catch (132) formed on the trailing protrusion (121) and the inner catch (122) formed on the leading protrusion (131) are caught with each other, thereby forming a firm connection between the trailing frame (120) and the leading frame (130).

[0093] Depending on the design conditions, the rear protrusion (121) may have an insertion protrusion (311) formed on the outer surface to fit into an insertion groove (251).

[0094] Accordingly, in the process of inserting the module frame (200) described below into the slide home (110) formed by combining the rear frame (120) and the front frame (130), the insertion projection (311) may be configured to be inserted into the insertion home (251) formed in the module frame (200).

[0095] FIG. 5 is a bottom perspective view showing a first embodiment of a module frame in a BIPV module according to the present invention, FIG. 6 is a cross-sectional view showing a first embodiment of a module frame in a BIPV module according to the present invention, FIG. 7 is a cross-sectional view showing an example in which a first module frame in a BIPV module according to the present invention is inserted into an outer frame and moved toward the front side, and FIG. 8 is a cross-sectional view showing an example in which a first module frame in a BIPV module according to the present invention is in close contact with the back side of a second module frame.

[0096] The module frame (200) is connected to the four sides of the solar module (10) and performs the function of moving the solar module (10) toward the front side by tightening the bolts (290). Referring to FIGS. 5 to 8, the configuration of the module frame (200) according to the first embodiment is composed of a first module frame (210) and a second module frame (220).

[0097] At this time, the first module frame (210) and the second module frame (220) are configured to be assembled with each other, and the first module frame (210) is coupled to one selected from both sides and the upper and lower sides of the solar module (10), and the second module frame (220) is configured to be coupled to the remaining one selected from the upper and lower sides of the solar module (10).

[0098] That is, the first module frame (210) coupled to each of the two sides of the solar module (10) is inserted into the slide groove (110) of the outer frame (100) and coupled, and the first module frame (210) coupled to one selected from the upper and lower sides of the solar module (10) and the second module frame (220) coupled to the other one are provided in a checkerboard pattern to couple the upper and lower sides of the solar module (10) to each other, thereby connecting the solar modules (10) arranged upper and lower.

[0099] Referring to FIGS. 5 and 6, the first module frame (210) is described in detail. It is configured to have a 'ㄷ' cross-sectional shape with one side opened by the first extension (211), the first pillar (212), and the first bend (213), and a solar module (10) is inserted into the opened space.

[0100] Depending on the design conditions, the first module frame (210) and the second module frame (220) that are connected to the four sides of the solar module (10) may be provided in the form of a square frame by diagonally cutting adjacent portions in a grid shape to facilitate connection at the corners of the solar module (10).

[0101] The first extension (211) is formed on the floor and is combined to wrap around a portion of the back surface of the solar module (10).

[0102] At this time, the first extension (211) is formed with a first socket (215) in a form that is dug inward on the back side as shown in FIG. 5, and a bolt (290) that is fastened to a screw thread formed on the inner surface of the first socket (215) is provided.

[0103] This will be described in detail with reference to Fig. 5. By perforating a portion of the back surface of the first extension part (211) to form screw threads on the inner surface, a first socket (215) opened toward the back surface of the first extension part (211) is formed.

[0104] This first socket (215) is fastened with a bolt (290) on the back side of the first extension (211).

[0105] Here, referring to FIG. 7, when the first module frame (210) is fitted into the slide groove (110) of the outer frame (100) and the bolt (290) is rotated, the rear end of the bolt (290) is supported on the bottom surface of the outer frame (100) where the slide groove (110) is formed, and the first expansion portion (211) is pushed toward the front side. As a result, the first buffer portion (214) described below is moved toward the front side and comes into close contact with the back surface of the outer frame (100) where the slide groove (110) is formed.

[0106] In addition, referring to FIG. 8, when the first module frame (210) is fitted to the back side of the second cover part (224) of the second module frame (220), and the bolt (290) is rotated, the rear end of the bolt (290) is supported on the bottom surface of the outer frame (100) in which the slide home (110) is formed, and the first extension part (211) is pushed toward the front side, and as a result, the first buffer part (214) of the first module frame (200) coupled to one solar module (10) moves toward the front side and comes into close contact with the back side of the second cover part (224) of the second module frame (220) coupled to another solar module (10).

[0107] At this time, a plurality of first sockets (215) can be formed spaced apart from each other along the longitudinal direction of the first extension (211).

[0108] Here, the first socket (215) can be formed by perforating the back surface of the first extension (211) and then forming a screw thread on the inner surface of the perforated space, or by perforating and then inserting a nut to secure it.

[0109] Depending on the design conditions, the first extension (211) may be formed by a plurality of grooves dug in the front side of the bottom surface spaced apart from each other, as described with reference to FIG. 6.

[0110] These multiple grooves facilitate heat dissipation and can reduce material usage, thus minimizing manufacturing costs.

[0111] Meanwhile, the first module frame (210) coupled to each of the two sides of the solar module (10) is configured to be inserted into the slide groove (110) of the outer frame (100) and moved toward the front side by tightening the bolt (290) from the outer frame (100). However, depending on the design conditions, the first module frame (210) coupled to the upper or lower side of the solar module (10) may be configured by omitting the first socket (215).

[0112] The first pillar (212) is formed in an extended form by being bent toward the front side at the other end of the first extension (211).

[0113] This first pillar part (212) separates the first extension part (211) and the first bend part (213) described later from each other, thereby forming a space into which a solar module (10) is inserted.

[0114] The first bend (213) is formed in a form that is bent to one side and extended from the tip of the first pillar (212), and a first fitting groove (213a) is formed in the form of an inwardly dug shape at the tip.

[0115] This first fitting groove (213a) provides a space into which the first buffer portion (214) described later is fitted.

[0116] The first buffer portion (214) is made of a flexible material having elasticity like rubber, and as shown in the attached drawing, it is fitted into the first fitting groove (213a) so as to protrude toward the front side of the first bend portion (213).

[0117] According to this configuration, the first module frame (210) is fitted into the slide home (110) of the outer frame (100), and when the bolt (290) is rotated, the bolt (290) supported on the front side of the bottom surface of the outer frame (100) pushes the first module frame (210) toward the front side.

[0118] Accordingly, the solar module (10) coupled with the first module frame (210) moves toward the front side, and at this time, the first buffer part (214) presses the back side of the outer frame (100) in which the slide home (110) is formed, so that the outer frame (100) and the solar module (10) are completely pressed together by elastic force, and no gap is formed between them, thereby improving airtightness and watertightness.

[0119] Referring to FIGS. 5 and 6, the second module frame (220) is configured to include a second extension portion (221), a second pillar portion (222), a second bend portion (223), and a second cover portion (224), with one side having the first module frame (210) attached to it and the other side being connected to one selected from the upper or lower side of the solar module (10).

[0120] The second extension (221) is formed on the floor and is combined to wrap around a portion of the back surface of the solar module (10).

[0121] Depending on the design conditions, the second extension (221) may be formed by a plurality of grooves dug in the front side of the bottom surface spaced apart from each other, as described with reference to FIG. 6.

[0122] These multiple grooves facilitate heat dissipation and can reduce material usage, thus minimizing manufacturing costs.

[0123] The second pillar (222) is formed in an extended form by bending toward the front side of one end of the second extension (221).

[0124] This second pillar (222) separates the second extension (221) and the second bending portion (223) described later from each other, thereby forming a space into which the solar module (10) is inserted.

[0125] The second bend (223) is formed in a form that is bent to the other side and extended from the tip of the second pillar (222).

[0126] The second module frame (220) is configured to have a 'ㄷ' cross-sectional shape with the other side open by the second extension (221), the second pillar (222), and the second bend (223), and the solar module (10) is inserted into the open space.

[0127] At this time, as shown in Fig. 6, the first bend portion (213) and the second bend portion (223) may be formed such that a portion thereof extends in a flat shape toward the outside, and the remaining portion thereof is formed in a slanted shape toward the bottom.

[0128] Furthermore, a protrusion (not shown in the drawing symbol) protruding toward the back may be formed at the part where the flat part and the slanted part are connected.

[0129] Depending on the design conditions, when combining the solar module (10) and the first module frame (210), and when combining the solar module (10) and the second module frame (220), an adhesive such as silicone may be applied to the combined portion.

[0130] The second cover part (224) is formed in a form that is bent to one side and extended from the tip of the second pillar part (222), and in the process of the first module frame (210) and the second module frame (220) being in close contact, the first module frame (210) is fitted to the back side of the second cover part (224).

[0131] At this time, as shown in Fig. 6, the second cover part (224) may have a part that extends in a flat shape toward the outside, and the remaining part that extends in a slanted shape toward the bottom.

[0132] According to this configuration, the first module frame (210) is fitted into the slide home (110) of the outer frame (100), and when the bolt (290) is rotated, the bolt (290) supported on the front side of the bottom surface of the outer frame (100) pushes the first module frame (210) toward the front side.

[0133] Accordingly, referring to FIG. 8, one solar module (10) coupled to the first module frame (210) moves toward the front side, and the first buffer portion (214) provided in the first module frame (210) presses the back side of the second cover portion (224) of the second module frame (220) coupled to another solar module (10), so that a pair of solar modules (10) arranged upper and lower are completely pressed together by elastic force, and no gap is formed between them, thereby improving airtightness and watertightness.

[0134] In addition, when multiple solar modules are installed in an inclined shape, the first module frame (210) and the second module frame (220) are in close contact to form a drainage channel so that rainwater, etc. flows along the entire inclined surface of the solar modules (10), preventing it from flowing onto the roof or outer wall.

[0135] Depending on the design conditions, the first pillar part (212) and the second pillar part (222) may be configured with an insertion groove (251) that is dug inward on the side that is in close contact with each other and an insertion projection (311) that is fitted into the insertion groove (251), as described with reference to FIG. 6.

[0136] For example, as illustrated in FIG. 6, an insertion groove (251) having an inwardly dug shape is formed on the other side of the first pillar portion (212), and correspondingly, an insertion projection (311) protruding outward is formed on one side of the second pillar portion (222), so that when the first module frame (210) and the second module frame (220) are combined, the insertion projection (311) can be inserted into the insertion groove (251) to improve the bonding strength.

[0137] Here, the insertion protrusion (311) may be formed long along the longitudinal axis of the module frame (200), as shown in the attached drawing, or may be formed in a hemispherical shape with multiple protrusions spaced apart from each other along the longitudinal axis of the module frame (200).

[0138] FIG. 9 is a bottom perspective view showing a second embodiment of a module frame in a BIPV module according to the present invention, FIG. 10 is a bottom perspective view showing a second embodiment of a module frame and a clamp in a BIPV module according to the present invention, FIG. 11 is a perspective view showing a clamp in a BIPV module according to the present invention, FIG. 12 is a front cross-sectional view showing an example of a BIPV module according to the present invention in which a module frame and a clamp are installed, and FIG. 13 is a cross-sectional view showing an example of a BIPV module according to the present invention in which a module frame is closely attached to the back side of a clamp.

[0139] Referring to FIGS. 9 to 13, a second embodiment of the module frame (200) will be described. The module frame (200) is coupled to each of the four sides of the solar module (10) and is configured to include an extension portion (240), a pillar portion (250), a bending portion (260), and a buffer portion (270).

[0140] This module frame (200) is formed by combining a pair of solar modules (10) in a symmetrical manner on each side adjacent to each other.

[0141] At this time, the module frames (200) coupled to each of the two sides of the solar module (10) are inserted into the slide grooves (110) of the outer frame (100) and coupled, and the module frames (200) coupled to each of the upper and lower sides of the solar module (10) are provided in a checkerboard pattern to connect the upper and lower sides of the solar module (10) to each other, but a clamp (300) is provided between them to prevent a gap from being formed between a pair of module frames (200) that are symmetrical to each other.

[0142] Referring to FIGS. 9 and 10, the module frame (200) coupled to one side of the clamp (300) among the pair of module frames (200) is configured to have a 'ㄷ' cross-sectional shape with one side opened by an expansion portion (240), a pillar portion (250), and a bending portion (260), and a solar module (10) is inserted into the opened space.

[0143] Additionally, the module frame (200) coupled to one side of the clamp (300) is provided in a symmetrical shape with respect to the module frame (200) coupled to one side of the clamp (300).

[0144] At this time, when combining the solar module (10) and the module frame (200), an adhesive such as silicone may be applied to the combined portion.

[0145] For example, by applying silicone to a space opened on one side by an extension portion (240), a pillar portion (250), and a bend portion (260), and then inserting a solar module (10) into the space, the bonding strength can be improved.

[0146] Depending on the design conditions, the module frame (200) that is connected to the four sides of the solar module (10) may be provided in the form of a square frame by diagonally cutting adjacent parts in a grid shape to facilitate connection at the corners of the solar module (10).

[0147] The extension (240) is formed on the floor and is combined to wrap around a portion of the back surface of the solar module (10).

[0148] At this time, the extension part (240) is formed with a socket (280) in a form that is dug inward on the back side as shown in Fig. 9, and is provided with a bolt (290) that is fastened to a screw thread formed on the inner surface of the socket (280).

[0149] This will be described in detail with reference to Fig. 9. By perforating a portion of the back surface of the extension part (240) to form screw threads on the inner surface, a socket (280) open to the back surface of the extension part (240) is formed.

[0150] These sockets (280) allow the bolts (290) to be fastened on the back side of the extension (240).

[0151] Accordingly, when the module frame (200) is fitted into the slide groove (110) of the outer frame (100) and the bolt (290) is rotated, the rear end of the bolt (290) is supported on the bottom surface of the outer frame (100) where the slide groove (110) is formed, and the expansion portion (240) is pushed toward the front side. As a result, the buffer portion (270) described later is moved toward the front side and comes into close contact with the back surface of the outer frame (100) where the slide groove (110) is formed.

[0152] At this time, a plurality of sockets (280) can be formed spaced apart from each other along the longitudinal direction of the extension part (240).

[0153] Here, the socket (280) can be formed by perforating the back surface of the extension (240) and then forming a screw thread on the inner surface of the perforated space, or by inserting a nut and fixing it after perforating.

[0154] Depending on the design conditions, the extension (240) may be formed by a plurality of grooves dug in the front side of the bottom surface spaced apart from each other, as described with reference to FIG. 10.

[0155] These multiple grooves facilitate heat dissipation and can reduce material usage, thus minimizing manufacturing costs.

[0156] Meanwhile, the module frame (200) coupled to each of the two sides of the solar module (10) is configured to be inserted into the slide home (110) of the outer frame (100) and moved toward the front side by tightening the bolt (290) from the outer frame (100). However, depending on the design conditions, the module frame (200) coupled to the upper and lower sides of the solar module (10) may be configured by omitting the socket (280).

[0157] The pillar part (250) is formed in an extended form by being bent toward the front side at the other end of the extension part (240).

[0158] This pillar part (250) separates the expansion part (240) and the bending part (260) described later from each other, thereby forming a space into which the solar module (10) is inserted.

[0159] The bending portion (260) is formed in a form that is bent to one side and extended from the tip of the column portion (250), and an insertion groove (261) in the form of an inwardly dug shape is formed at the tip.

[0160] This fitting groove (261) provides a space into which a buffer part (270) described later is fitted.

[0161] At this time, the bending portion (260) may be formed in a form that is bent to one side and extended from the tip of the column portion (250), as illustrated in FIG. 10, but a part thereof may be formed in a flat form as it goes outward, and the remaining part may be formed in a form that is inclined as it goes downward.

[0162] Furthermore, a protrusion (not shown in the drawing symbol) protruding toward the back may be formed at the part where the flat part and the slanted part are connected.

[0163] This is because, in the process of inserting the solar module (10) into the space between the expansion portion (240), the pillar portion (250), and the bend portion (260), the projection and a portion of the end formed in the bend portion (260) are inclined toward the back side, thereby allowing the solar module (10) to adhere more closely to the front side and improve the bonding strength.

[0164] The buffer part (270) is made of a flexible material with elasticity like rubber, and as shown in the attached drawing, it is fitted into the fitting groove (261) so as to protrude toward the front side of the tip of the bending part (260).

[0165] According to this configuration, the module frame (200) coupled to each of the two sides of the solar module (10) is inserted into the slide home (110) of the outer frame (100), and when the bolt (290) is rotated, the bolt (290) supported on the front side of the bottom surface of the outer frame (100) pushes the module frame (200) toward the front side.

[0166] Accordingly, the solar module (10) combined with the module frame (200) moves toward the front side, and at this time, the buffer part (270) presses the back side of the outer frame (100) where the slide home (110) is formed, so that the outer frame (100) and the solar module (10) are completely pressed together by elastic force, and no gap is formed between them, thereby improving airtightness and watertightness.

[0167] The clamp (300) is provided to have a longitudinal length in the left and right directions between the module frames (200) that are symmetrically connected to the upper and lower sides of the solar module (10), and is configured to include an upright portion (310), a cover portion (320), and an extension portion (330).

[0168] The upright part (310) is provided between a pair of symmetrical solar modules (10).

[0169] That is, in the process of arranging a pair of solar modules (10) upward and downward, the upright part (310) is provided between a pair of module frames (200) and is in close contact with them.

[0170] Depending on the design conditions, the pillar portion (250) and the upright portion (310) that are in close contact with each other can be configured with an insertion groove (251) that is dug inward on the side that is in close contact with each other and an insertion projection (311) that is fitted into the insertion groove (251), as described with reference to FIG. 10.

[0171] For example, as illustrated in FIG. 10, an insertion groove (251) having an inwardly dug shape is formed on the outer surface of the column portion (250), and correspondingly, an insertion projection (311) protruding outward is formed on the outer surface of the upright portion (310), so that when the module frame (200) and the clamp (300) are brought into close contact with each other, the insertion projection (311) is inserted into the insertion groove (251), thereby improving the bonding strength.

[0172] The cover part (320) is formed in an extended form by being bent on both sides at the top of the upright part (310), and in the process of the module frame (200) and the clamp (300) being brought into close contact, the module frame (200) is fitted to the back side of the cover part (320).

[0173] At this time, as shown in Fig. 10, the cover part (320) may have a part that extends in a flat shape toward the outside, and the remaining part that extends in a slanted shape toward the bottom.

[0174] The extension part (330) is formed in a form that extends outward from the end of the cover part (320), so that when both sides of the solar module (10) are each fitted into the slide home (110) of the clamp (300), the extension part (330) is fitted into the slide home (110) together.

[0175] At this time, since the extension part (330) is formed with a thickness thinner than the front and rear thickness of the cover part (320), as shown in FIG. 11, a step (331) is formed.

[0176] By means of this step (331), the extension part (330) is fitted into the slide home (110), and the relatively thick cover part (320) is pressed against the front side of the module frame (200).

[0177] Depending on the design conditions, the extension (330) may be provided with a sealing portion (332) protruding on both sides at the end, as described with reference to FIGS. 11 and 12.

[0178] This sealing member (332) covers the side of the buffer member (270) when the module frame (200) comes into contact with the side of the upright member (310) after the extension member (330) is fitted into the slide home (110) of the outer frame (100), thereby preventing rainwater, etc. from flowing into the space formed between the extension member (330) and the buffer member (270), and allowing it to flow only from the upper side to the lower side along the plurality of solar modules (10) arranged in the upper and lower sides.

[0179] According to this configuration, when the module frame (200) is fitted into the slide home (110) of the outer frame (100), and the bolt (290) is rotated, the bolt (290) supported on the front side of the bottom surface of the outer frame (100) pushes the module frame (200) toward the front side.

[0180] Accordingly, the solar module (10) to which the module frame (200) is coupled is moved to the front side, so that the buffer parts (270) provided on each of the two sides of the solar module (10) are in close contact with the back side of the outer frame (100), and at least one selected from among the buffer parts (270) provided on the upper and lower sides of the solar module (10) is in close contact with the back side of the cover part (320).

[0181] That is, as the buffer portion (270) provided on the four sides of the solar module (10) is in close contact with the back side of the outer frame (100) and the clamp (300), no gap is formed between the outer frame (100) and the solar module (10) and between the solar module (10) and the clamp (300), thereby improving airtightness and watertightness.

[0182] Fig. 14 is a perspective view showing a joint in a BIPV module according to the present invention, and Fig. 15 is an exploded perspective view showing a joint in a BIPV module according to the present invention.

[0183] Depending on the design conditions, the module frame (200) that is connected to the four sides of the solar module (10) may be provided with a connecting portion (400) so that the ends are connected to each other.

[0184] At this time, the connecting portion (400) may be provided at each corner of the solar module (10).

[0185] This joint (400) is formed by overlapping a portion of the ends of a pair of module frames (200) with each other, and then inserting a nut (420) into a connecting hole (410) that is connected to each other, thereby connecting the ends of a pair of module frames (200) with each other.

[0186] This will be described in detail with reference to FIGS. 14 and 15. The ends of a pair of module frames (200) provided at the corners of the solar module (10) have diagonal cut surfaces, but a portion of the extension (240) may be formed in a rectangular shape that extends outward without being diagonally cut.

[0187] That is, as shown in Fig. 15, the extension part (240) has a square end, and the pillar part (250) and the bending part (260) are formed by diagonal cutting.

[0188] At this time, a part of the end of the extension (240) formed in a square shape may have a joining hole (410) formed.

[0189] Preferably, a coupling hole (410) that is open toward the back side may be formed at the end of an extension (240) of one module frame (200), as shown in FIG. 15, and a coupling hole (410) that is open toward the front and back sides may be formed at the end of an extension (240) of another module frame (200) adjacent thereto.

[0190] Accordingly, as shown in Fig. 15, a pair of module frame (200) extensions (240) each having a connecting hole (410) formed therein are overlapped, and then a nut (420) is inserted from the back side toward the front side into a pair of connected connecting holes (410), thereby firmly connecting a pair of module frames (200).

[0191] Here, the coupling hole (410) may be formed to have a hexagonal cross-section so that the nut (420) can be forcibly fitted, and the length of the coupling hole (410) corresponding to the outer circumference of the nut (420) may be equal to or smaller than the length of the outer circumference of the nut (420).

[0192] Furthermore, the total depth of the coupling hole (410) formed in each of a pair of module frames (200) formed in the direction in which the nut (420) is inserted may be equal to or greater than the thickness of the nut (420).

[0193] Meanwhile, FIGS. 14 and 15 illustrate examples of the configuration of a joint part (400) for the second embodiment of a module frame (200) coupled to four sides of a solar module (10), but depending on the design conditions, it can be applied to the corner portions where the first module frames (210) and the first module frames (210) are adjacent and the corner portions where the first module frames (210) and the second module frames (220) are adjacent, and can be configured in the first embodiment of the module frame (200).

[0194] According to this configuration, the BIPV module according to the present invention forms an insulation layer in the space between the roof and the solar module (10) or between the outer wall and the solar module (10), thereby minimizing deformation and efficiency reduction due to temperature changes, and minimizing the gap between adjacent solar modules (10), thereby improving insulation and watertightness.

[0195] In addition, the present invention is configured so that the module frame (200) that wraps around the side of the solar module (10) is in close contact with the outer frame (100) by tightening the bolt (290), thereby minimizing the installation of the structure, thereby improving workability and improving watertightness and airtightness.

[0196] In addition, the present invention provides a clamp between solar modules (10) spaced apart from each other in the upper and lower directions to seal and connect the solar modules (10), thereby inducing rainwater and the like to flow along the solar modules (10) spaced apart from each other in the upper and lower directions and preventing them from flowing onto the roof or outer wall.

[0197] In addition, the present invention has the advantage of being applicable to solar modules (10) having various specifications regardless of the size or type of the solar module (10), since the module frame (200) is coupled to surround the four sides of the solar module (10) and the module frames (200) are firmly coupled by the coupling portion (400).

[0198] Although the above description has presented and described various embodiments of the present invention, the present invention is not necessarily limited thereto, and it will be apparent to those skilled in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention.
