Description

  The present invention relates to a module frame that holds a solar cell module body and a solar cell module that includes the module frame.

  The solar cell module main body with the built-in solar cell includes a translucent substrate disposed on the light receiving surface side, a solar cell disposed opposite to the translucent substrate, and a sealing portion for sealing the solar cell A back surface protection member for protecting the back surface is laminated. In general, a glass substrate is used as the translucent substrate, EVA (ethylene vinyl acetate), for example, is used as the sealing portion, and a sealing sheet (PET / Al / PET (PET), for example, is used as the back surface protection member. : Polyethylene terephthalate)).

  Therefore, in order to prevent intrusion of moisture and the like from the end face of the solar cell module main body, and to secure the installation strength of the solar cell module main body, the module frame body into which the periphery of the laminate including the translucent substrate is fitted Is needed.

  Since the solar cell module body is generally formed in a rectangular shape, four module frame bodies that support the periphery of the solar cell module body are combined into a rectangular module frame body.

  However, various techniques have been proposed for fastening the four frames constituting each side of the rectangle to each other because the corner portion has a special shape as compared to the straight side. Further, a technique for connecting four module frame bodies to each other to form a rectangle has been proposed (see, for example, Patent Document 1 and Patent Document 2).

  As a method of fixing and connecting module frames at the corners where the module frames are connected to each other, a method of using “screws” as a fastening jig and a joint member, “caulking” or “fitting” ", There is a method of connecting the module frame bodies facing each other.

  Patent Document 1 discloses both a fastening technique using screws and a caulking technique. Patent Document 2 discloses a caulking technique for inserting a press-fitting member into a frame.

  In the caulking technique disclosed in Patent Document 1, an L-shaped fixing fitting is inserted into both frames (module frame bodies) to be connected to connect the frames to each other. Assembling is done only by fitting without fixing the fixing bracket with screws. Therefore, the method of using the fixing metal and the shape of the frame are special, and there is a possibility that a problem in strength occurs.

  The caulking technique disclosed in Patent Document 2 uses a press-fitting member as a joint member. Since the press-fitting member affects the shape of the frame, there is a possibility that a problem in strength occurs.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<Embodiment 1>
With reference to FIG. 1A thru | or FIG. 1C, the solar cell module 1 and the module frame 20 which concern on this Embodiment are demonstrated.

  FIG. 1A is a plan view showing an outline of solar cell module 1 and module frame 20 according to Embodiment 1 of the present invention as seen in a plan view.

  The solar cell module 1 according to the present embodiment includes a solar cell module main body 10 including a cell region 12 in which solar cells 11 are arranged and an outer peripheral region 13 arranged on the outer periphery of the cell region 12, and the solar cell module main body 10. Of the plurality of module frames 20 (in this embodiment, the first module frame 20a, the second module frame 20b, the third module frame 20c, the fourth module frame 20d, 5 of the 5 module frame 20e).

  In the following, it is not necessary to distinguish the first module frame 20a, the second module frame 20b, the third module frame 20c, the fourth module frame 20d, and the fifth module frame 20e from each other, or When expressing the whole, the module frame 20 may be simply used.

  The solar cell module main body 10 can secure positioning accuracy and mechanical strength because the outer peripheral region 13 is supported and protected by the module frame 20. In addition, the solar cell module body 10 is laminated with a translucent substrate disposed on the light receiving surface side, a solar cell 11, a sealing portion that seals the solar cell 11, and a back surface protection member that protects the back surface. . In general, a glass substrate is used as the translucent substrate, EVA (ethylene vinyl acetate), for example, is used as the sealing portion, and a sealing sheet (PET / Al / PET (PET), for example, is used as the back surface protection member. : Polyethylene terephthalate)).

  In the present embodiment, since the solar cell module main body 10 is pentagonal, the module frame 20 is also pentagonal according to the solar cell module main body 10. That is, the module frame 20 is obtained by combining the first module frame 20a, the second module frame 20b, the third module frame 20c, the fourth module frame 20d, and the fifth module frame 20e with each other (mutually It is a pentagon).

  The reason why the shape of the solar cell module 1 in a plan view is a pentagon is to match the situation of the installation place (for example, the rooftop or roof of a building). That is, the planar shape of the solar cell module 1 can be changed from a general rectangle to, for example, a triangle, a pentagon, and the like. The module frame 20 according to the present embodiment is applied to the solar cell module 1 having a polygon other than a rectangle. By making the polygon according to the situation of the installation location, the installation location can be effectively utilized to maximize the generated power.

  In solar cell module 1 according to the present embodiment, solar cell module body 10 is preferably a pentagon or more polygon in plan view. Therefore, the solar cell module 1 can be applied to the solar cell module body 10 having a polygonal shape exceeding a quadrangle, and the reliability of the connecting portion 40 can be ensured.

  The module frame 20 is formed by extrusion (extrusion). Therefore, it is set as the state which has the same cross section in the length direction (namely, direction of each edge | side which the solar cell module main body 10 made into the polygon by planar view has). Moreover, the shape in a cross section perpendicular | vertical to a length direction can be set easily and with high precision.

  The module frame 20 is preferably made of aluminum or an aluminum alloy. The material to be used is appropriately selected in consideration of the balance between strength and lightness.

  In the solar cell module 1, the first module frame body 20a and the second module frame body 20b are connected to each other at an internal angle θ1 (for example, 90 degrees) via the connecting portion 41, and the second module frame body 20b and the third module frame body are connected. 20c is connected at an inner angle θ2 (for example, 90 degrees) through the connecting portion 42, and the third module frame body 20c and the fourth module frame body 20d are at an inner angle θ3 (for example, 130.8 degrees) through the connecting portion 43. The fourth module frame body 20d and the fifth module frame body 20e are connected at an internal angle θ4 (for example, 139.2 degrees) via the connection portion 44, and the fifth module frame body 20e and the first module frame body 20a are Are connected at an internal angle θ5 (for example, 90 degrees) through the connecting portion 45.

  The solar cell module body 10 has a pentagonal shape, and three positions of the inner angle θ1, the inner angle θ2, and the inner angle θ5 are right angles, and the two positions of the inner angle θ3 and the inner angle θ4 are different from 90 degrees.

  In the following description, the connecting portion 41, the connecting portion 42, the connecting portion 43, the connecting portion 44, and the connecting portion 45 may be simply referred to as the connecting portion 40 when it is not necessary to distinguish them from each other.

  Further, in the connecting portion 41, the first module frame body 20a and the second module frame body 20b are fastened (connected) by the fastening member 51, and in the connecting portion 42, the second module frame body 20b and the third module frame body 20c. Are fastened (coupled) by the fastening member 52, and the third module frame body 20 c and the fourth module frame body 20 d are fastened (coupled) by the fastening member 33 a and the fastening member 33 b via the joint member 31 in the joint portion 43. In the connecting portion 44, the fourth module frame body 20d and the fifth module frame body 20e are fastened (connected) by the fastening member 33c and the fastening member 33d via the joint member 32. In the connecting portion 45, the fifth module The frame body 20e and the first module frame body 20a are fastened (connected) by a fastening member 53.

  In the following description, the joint member 31 and the joint member 32 may be simply referred to as the joint member 30 when it is not necessary to distinguish between them. Further, when there is no need to distinguish the fastening member 33a, the fastening member 33b, the fastening member 33c, and the fastening member 33d from each other, the fastening member 33 may be simply used. Moreover, when it is not necessary to distinguish the fastening member 51, the fastening member 52, and the fastening member 53 from each other, the fastening member 50 may be simply used.

  Since the inner angle θ1, the inner angle θ2, and the inner angle θ5 are right angles, the connecting portion 41, the connecting portion 42, and the connecting portion 45 can specifically adopt the following connecting structure.

  In the connecting portion 41, the first wall portion 26 (see FIG. 3) of the second module frame body 20b protrudes from the second module frame body 20b and comes into contact with the end surface of the first module frame body 20a. Since the screws are formed on the second wall portion 28 (see FIG. 3) of the first module frame 20a, they are fitted into the screw portions 29 (see FIG. 3) and screwed. By adopting the screwing structure, it is possible to easily disassemble and reuse the component parts.

  The first wall portion 26 is also an outer wall because the position relative to the second wall portion 28 is on the outside, and the second wall portion 26 is positioned on the inside relative to the first wall portion 26. It is also an inner wall. That is, since the second wall portion 28 is integrally connected to the upper end portion 24, the lower end portion 25, and the first wall portion 26, the support portion 23 forms a rectangular hollow structure.

  In addition, since the end surface of the 1st module frame 20a in the connection part 41 is orthogonally formed with respect to the length direction of the 1st module frame 20a, fastening at a right angle is made with high precision. . Moreover, the 1st wall part 26 of the 2nd module frame 20b is made into a highly accurate plane.

  In the connecting portion 42, the first wall portion 26 (see FIG. 3) of the second module frame 20b protrudes from the second module frame 20b and comes into contact with the end surface of the third module frame 20c, so that a fastening member 52 (for example, Screws are formed on the second wall portion 28 (see FIG. 3) of the third module frame 20c, so that they are fitted into the screw portion 29 (see FIG. 3) and screwed.

  In addition, since the end surface of the 3rd module frame 20c in the connection part 42 is orthogonally formed with respect to the length direction of the 3rd module frame 20c, the fastening at a right angle is made with high precision. . Moreover, the 1st wall part 26 of the 2nd module frame 20b is made into a highly accurate plane.

  In the connecting portion 45, the first wall portion 26 (see FIG. 1B) of the fifth module frame body 20e protrudes from the fifth module frame body 20e and comes into contact with the end surface of the first module frame body 20a. Since the screws are formed on the second wall portion 28 (see FIG. 3) of the first module frame 20a, they are fitted into the screw portions 29 (see FIG. 3) and screwed.

  In addition, since the end surface of the 1st module frame 20a in the connection part 45 is formed orthogonally with respect to the length direction of the 1st module frame 20a, fastening at a right angle is made with high precision. . Further, the first wall portion 26 of the fifth module frame 20e is a highly accurate plane.

  Since the inner angle θ3 and the inner angle θ4 are different from the right angle, the joint member 30 is applied to the connecting portion 41, the connecting portion 42, and the connecting portion 45. A connection structure different from the connection part 42 and the connection part 45 is adopted. Specifically, it is as follows.

  In the connecting portion 43, the end surface of the third module frame body 20c and the end surface of the fourth module frame body 20d are formed so as to form an internal angle θ3 (for example, 130.8 degrees different from 90 degrees) and are abutted against each other. They are connected by a joint member 31. Therefore, the joint member 31 (joint member 30) is formed of a single plate material.

  The fastening member 52 is applied to the third module frame 20c at the connecting portion. Therefore, the third module frame 20c has the screw portion 29 because the fastening member 52 is screwed. Moreover, since the internal thread part 29 is formed over the full length of the 3rd module frame 20c, the end surface of the 3rd module frame 20c in the connection part 43 will be in the state which has the internal thread part 29. (See FIG. 1C).

  In the fourth module frame 20d, the inner angle θ3 formed by the connecting portion 43 and the inner angle θ4 formed by the connecting portion 44 on the opposite side of the connecting portion 43 are different from the right angle. Accordingly, in the fourth module frame 20d, the female screw portion 29 applied by the connecting portion 40 whose inner angle is a right angle is not necessary, and there is no need to have the female screw portion 29. Therefore, the fourth module at the connecting portion 43 is not required. The end surface of the frame body 20d does not have the female thread portion 29 (see FIG. 1B).

  Therefore, in the third module frame 20c in the connecting portion 43, the joint member 31 is inserted into the space formed between the first wall portion 26 and the female screw portion 29 (see FIG. 1C), and the third module frame 20c in the connecting portion 43 In the 4-module frame 20d, the joint member 31 is inserted into a space (see FIG. 1B) formed inside the first wall portion 26.

  In the module frame 20 (fourth module frame 20d), a restricting portion 27a for restricting the position of the joint member 31 from the first wall portion 26 in order to accurately position the joint member 31 (see FIG. 1B). Is disposed at the lower end 25. The restriction portion 27a (hereinafter, simply referred to as the restriction portion 27) is formed as a protrusion with respect to the lower end portion 25, for example, and is formed by extrusion processing. Therefore, the length direction of the module frame 20 It is formed to extend.

  That is, in the fourth module frame body 20d in the connecting portion 43, the joint member 31 is disposed between the first wall portion 26 and the restricting portion 27a, so that the joint member 31 extends along the first wall portion 26. Since positioning can be performed with high accuracy, positioning with the same accuracy as that of the third module frame 20c side of the connecting portion 43 is possible.

  Since the fourth module frame body 20d is formed by extrusion, the state without the female thread portion 29 is formed over the entire fourth module frame body 20d, and the connection portion 44 has the same state. It is said.

  As described above, in the connecting portion 43, the joint member 31 is similarly extended and disposed on both the third module frame body 20c and the fourth module frame body 20d, and is similarly positioned. The joint member 31 is fastened to the third module frame 20c by the fastening member 33b and fastened to the fourth module frame 20d by the fastening member 33a.

  That is, the flat joint member 31 bent at the inner angle θ3 is fastened to the third module frame 20c constituting the connecting portion 43 via the fastening member 33b, and the fourth module frame constituting the connecting portion 43. Fastened to 20d via a fastening member 33a. Therefore, since the strength of the joint member 31 acts effectively as it is, the connecting portion 43 secures the same strength as the joint member 31 and fastens the third module frame body 20c and the fourth module frame body 20d with high accuracy. (See FIGS. 1B and 1C).

  In the connecting portion 44, the end surface of the fourth module frame body 20d and the end surface of the fifth module frame body 20e are formed so as to form an internal angle θ4 (for example, 139.2 degrees different from 90 degrees) and are abutted against each other. They are connected by a joint member 32.

  Moreover, in the connection part 45, since the 1st wall part 26 of the 5th module frame 20e protrudes from the 5th module frame 20e, and is connected with the internal thread part 29 which the 1st module frame 20a has, it is 5th. The module frame 20e does not need to have the female screw portion 29.

  Therefore, the end surface of the fifth module frame 20e at the connecting portion 44 is not in the state of having the female thread portion 29 as in the end surface of the fourth module frame 20d at the connecting portion 44 (see FIG. 1B).

  Therefore, in the connection portion 44, the joint member 32 is inserted into the space defined between the first wall portion 26 and the restriction portion 27a in both the fourth module frame body 20d and the fifth module frame body 20e. That is, the joint member 32 is fastened to the fourth module frame 20d by the fastening member 33c, and fastened to the fifth module frame 20e by the fastening member 33d. That is, the fastening state at the connecting portion 44 is the same as the fastening state of the fastening member 33a applied at the connecting portion 43 (see FIG. 1B).

  The flat joint member 32 bent at the internal angle θ4 is fastened to the fourth module frame 20d constituting the connecting portion 44 via the fastening member 33c, and is attached to the fifth module frame 20e constituting the connecting portion 44. On the other hand, it is fastened via the fastening member 33d. Therefore, since the strength of the joint member 32 acts effectively, the connecting portion 44 ensures the same strength as the joint member 32 and fastens the fourth module frame body 20d and the fifth module frame body 20e with high accuracy. (See FIG. 1B).

  FIG. 1B is an enlarged cross-sectional view showing an enlarged cross-sectional state of the joint member 31 taken along the arrow 1B-1B in FIG. 1A.

  FIG. 1B shows a connection state of the fourth module frame body 20d (module frame body 20) at the connection portion 43 (connection portion 40). In addition, the connection state in the connection part 44 of the 4th module frame 20d and the connection state in the connection part 44 of the 5th module frame 20e are also the same.

  The module frame 20 according to the present embodiment has a module frame that holds a solar cell module body 10 that includes a cell region 12 in which the solar cells 11 are disposed and an outer peripheral region 13 that is disposed in the outer periphery of the cell region 12. This is a body 20 (fourth module frame body 20d).

  The module frame 20 includes a fitting portion 21 into which the outer peripheral region 13 is fitted, and a support portion 23 that supports the fitting portion 21, and the support portion 23 includes an upper end portion 24 that is coupled to the bottom portion 21 b of the fitting portion 21. , A lower end 25 that is arranged away from the upper end 24 in a direction crossing the solar cell module main body 10 (a direction crossing the plane of the solar cell module main body 10) and faces the upper end 24, and the upper end 24 and the lower end A first wall portion 26 that is connected to the portion 25 and disposed along the outer peripheral region 13, and is disposed between the upper end portion 24 and the lower end portion 25 along the first wall portion 26 and extends to be adjacent to the other portion. A joint member 31 (joint member 30) inserted into the module frame body 20 (third module frame body 20c), and a restricting portion 27a (restricting portion 27) for restricting the position of the joint member 31 from the first wall portion 26; With .

  Therefore, the module frame body 20 (fourth module frame body 20d) includes a joint member 31 (joint member 30) and a regulation portion 27a (regulation portion 27) that regulates the position of the joint member 31 from the first wall portion 26. Since it comprises, it becomes possible to position easily and with high precision with respect to the other adjacent module frame 20, and to connect reliably.

  Note that the fitting portion 21 and the support portion 23 are generally integrated. Further, the position of the restricting portion 27a from the first wall portion 26 is such that the joint member 31 is sandwiched between the restricting portion 27a and the first wall portion 26, and the joint member 31 is brought close to the first wall portion 26 by the restricting portion 27a. Although it is the position made into the made state, it is preferable. More specifically, the coupling member 31 is brought into contact with the first wall portion 26 by the regulation (induction) of the regulation portion 27a and is slid and inserted between the first wall portion 26 and the regulation portion 27a. Preferably there is.

  In addition, the 1st wall part 26 is arrange | positioned along the edge part of the outer periphery area | region 13 (the edge part of the solar cell module main body 10. In other words, the position which connects the outer end of the upper end part 24 and the lower end part 25). The Further, the distance between the first wall portion 26 and the second wall portion 28 is determined from the strength, balance, etc. as a support structure for the solar cell module body 10.

  In the fourth module frame body 20 d (module frame body 20), the restricting portion 27 a is disposed at the lower end portion 25 so as to face the upper end portion 24. With this configuration, the fourth module frame body 20d can be positioned in a self-aligned manner using the weight of the joint member 31, so that the interval from the first wall portion 26 can be easily determined. The module frame 20 can be easily connected. That is, workability, position accuracy, and strength can be ensured.

  In the 4th module frame 20d (module frame 20), it is preferred that regulation part 27a is a projection. With this configuration, the fourth module frame body 20d can restrict the position of the joint member 31 with a simple configuration because the restricting portion 27a is formed by a protrusion.

  Further, in the fourth module frame body 20 d (module frame body 20), it is preferable that the protrusion (the restriction portion 27 a) is extended along the length direction of the first wall portion 26. With this configuration, the fourth module frame body 20 d extends the protrusion along the extending direction of the first wall portion 26 (the direction along the outer periphery of the outer peripheral region 13), and thus the joint member 31 in the extending direction of the joint member 31. Since the position is restricted, more stable positioning can be achieved.

  Since the restricting portion 27a is arranged to extend in a continuous rail shape (projection) instead of a separated pin shape, a protrusion can be arranged corresponding to the entire length direction of the joint member 31. Therefore, positioning accuracy and mechanical strength are improved. As described above, since the module frame 20 is extrusion-molded, the protruding-line regulating portion 27a is easily and highly accurately formed.

  For example, the restricting portion 27a may be configured such that a suitable number of rod pins are dispersed and arranged. Since the restricting portion 27a is disposed only in a necessary portion, the module frame body 20 can be reduced in weight.

  In the fourth module frame body 20d (module frame body 20), the support portion 23 is disposed on the cell region 12 side with respect to the first wall portion 26 and connects the upper end portion 24 and the lower end portion 25 to the outer peripheral region 13. The 2nd wall part 28 arrange | positioned along is provided.

  In the module frame 20, it is preferable that the upper end part 24, the lower end part 25, the 1st wall part 26, and the 2nd wall part 28 form the hollow structure which includes the joint member 31 (joint member 30). With this configuration, the fourth module frame 20d (module frame 20) includes the joint member 30 by a hollow structure formed by the upper end 24, the lower end 25, the first wall 26, and the second wall 28. Therefore, damage to the joint member 30 can be prevented, and the reliability of the connection strength of the module frame 20 can be ensured.

  Further, the shape of the joint member 30 to be inserted is a plate shape arranged in parallel with the first wall portion 26. Since it is possible to fasten the adjacent module frame 20 only by fastening the joint member 30 to the 1st wall part 26 by the fastening member 33, it is only necessary to adjust the cross-sectional shape (plate thickness) of the joint member 30. The strength of the joint member 30 can be ensured as necessary.

  The cross-sectional shape of the joint member 30 (a rectangular cross-sectional shape in a direction crossing the length direction of the module frame 20; that is, a cross-section in the same direction as the arrows 1B-1B and 1C-1C in FIG. 1A) The long side (plate width, that is, the length in the vertical direction with respect to the solar cell module main body) is delimited by the interval between the upper end portion 24 and the lower end portion 25, and the short side (plate thickness) is defined by the restricting portion 27 of the joint member 30. An upper limit is defined in a range where the position is restricted. Further, the length of the plate is a length along the first wall portion 26 in the length direction of the module frame represented in plan view.

  Specifically, the range in which the position of the joint member 30 is restricted by the restriction portion 27 is, for example, the interval from the first wall portion 26 to the position where the protrusion of the restriction portion 27a rises in the case of the restriction portion 27a. In the case of the restricting portion 27e and the restricting portion 27f, it is the distance from the first wall portion 26 that the bottom portion of the recess into which the joint member 30 is inserted has.

  The plate width of the joint member 30 can be sufficiently secured between the upper end portion 24 and the support portion 23. In addition, the plate thickness of the joint member 30 can be sufficiently ensured corresponding to the interval at which the restricting portion 27 acts on the joint member 30 from the first wall portion 26. Therefore, the joint member 30 can ensure sufficient strength in conformity with the shape of the module frame body 20 (inner shape of the first wall portion 26) in terms of plate thickness and plate width.

  The joint member 30 is formed of, for example, aluminum or an aluminum alloy, like the module frame 20. By applying the same material as that of the module frame 20, the strength can be ensured with high accuracy.

  In the module frame 20, the upper end 24, the lower end 25, the first wall 26, and the second wall 28 preferably form a rectangle as a schematic shape. By making it a rectangle (a virtual rectangle as an assumed outer periphery including a state in which the portion of the second wall portion 28 is opened), the strength of the module frame 20 can be further improved.

  In the fourth module frame 20d (module frame 20), the joint member 31 (joint member 30) is preferably fastened to the first wall portion 26. With this configuration, the fourth module frame body 20d (module frame body 20) fastens the joint member 31 (joint member 30) to the first wall portion 26, thereby improving the connection strength and improving the connection reliability. Let That is, since the adjacent module frame bodies are connected in a state where the plane of the joint member 30 is in contact (fastened) with the plane of the first wall portion 26, the strength of the first wall portion is used as it is. It is possible to ensure strength.

  A fastening member 33 a (fastening member 33) can be applied as a member for fastening the joint member 30 to the first wall portion 26. The fastening member 33a is, for example, a screw (male screw). The fastening member 33a is arrange | positioned at two places in the orthogonal | vertical direction (direction between the upper end part 24 and the lower end part 25) of the 1st wall part 26 (and coupling member 31). In the module frame 20, the fastening strength is greatly improved by disposing the fastening members 33a at two places in the vertical direction, and the connection reliability is improved.

  Since the surface facing the first wall portion 26 of the joint member 30 is opposed to the first wall portion 26 and fastened by the fastening member 33, the entire basic shape of each of the joint member 30 and the first wall portion 26 is included. Is effectively used as the fastening means, and the fastening strength (connection strength) can be improved to the strength of the material itself.

  It is preferable that two fastening members 33a are arranged apart from both the upper end side (upper end portion 24 side) and the lower end side (lower end portion 25 side) of the joint member 31. Since it can oppose a rotational force by arrange | positioning away to both ends, more firm fastening is attained and the module frame 20 can be connected firmly and highly accurately. The fastening member 33 may be one instead of two.

  Moreover, in order to ensure the fastening strength by the screw as the fastening member 33a (fastening member 33), the plate thickness of the joint member 30 (thickness in the direction crossing the first wall portion 26) is a hollow structure (first wall portion). 26 to the second wall portion 28. Alternatively, the distance from the first wall portion 26 without the second wall portion 28 to the tip of the upper end portion 24 and the lower end portion 25) is half to three. It is preferable to set it to about 1 / min. With this configuration, the joint member 30 can be prevented from being deformed with respect to the hollow structure, so that the strength of the module frame 20 can be maintained.

  The position of the restricting portion 27 is arranged between the tip of the upper end 24 or the tip of the lower end 25 opposite to the first wall 26 or the first wall 26 away from the second wall 28. In this state, the joint member 30 is disposed at a position where it does not contact the tip of the upper end 24, the tip of the lower end 25, or the second wall portion 28.

  Between the solar cell module main body 10 and the module frame 20, for example, a buffer portion 15 made of an elastic body (rubber, resin) is disposed to suppress external impact on the solar cell module main body 10, and , Improve water tightness and environmental resistance.

  Since the module frame body 20 includes the flange portion 21s on the outer periphery of the fitting portion 21, it is possible to suppress the deformation of the first wall portion 26 to ensure strength and to ensure an appropriate external shape. Moreover, since the module frame 20 includes the reinforcing portion 28s near the lower end portion 25 of the second wall portion 28, the deformation of the second wall portion 28 can be suppressed and the strength can be ensured.

  FIG. 1C is an enlarged cross-sectional view showing an enlarged cross-sectional state of the joint member 31 taken along arrow 1C-1C in FIG. 1A.

  FIG. 1C shows a connection state of the third module frame body 20c (module frame body 20) at the connection portion 43 (connection portion 40). Since the basic configuration is the same as the configuration described in FIGS. 1A and 1B, different items will be mainly described.

  In the third module frame 20c (module frame 20), the support portion 23 is disposed on the cell region 12 side with respect to the first wall portion 26 and connects the upper end portion 24 and the lower end portion 25 to the outer peripheral region 13. 2nd wall part 28 arranged along the 2nd wall part 28, and the 2nd wall part 28 is arranged on the field opposite to the 1st wall part 26, and is adjacent to other module frame 20 (2nd module frame 20b). The first wall portion 26 is provided with a female screw portion 29 to be screwed, and the restricting portion 27 b (hereinafter simply referred to as the restricting portion 27) is constituted by the female screw portion 29.

  Therefore, the module frame body 20 (third module frame body 20c) has a female screw portion 29 (female screw) to which another adjacent module frame body 20 (first wall portion 26 of the second module frame body 20b) is screwed. Since the tip of the portion 29 on the first wall portion 26 side functions as the restricting portion 27b, it is not necessary to form the restricting portion 27 separately, and productivity (workability) and versatility are improved.

  That is, in the third module frame body 20c, a newly formed female screw portion 29 is applied as the restricting portion 27b, instead of newly forming the restricting portion 27. That is, the apex on the first wall portion 26 side of the female screw portion 29 formed on the second wall portion 28 and projecting toward the first wall portion 26 (the first female screw portion 29 is the first on the basis of the second wall portion 28. A vertex formed by a position close to the wall portion 26) functions as a restricting portion 27b for the joint member 31.

  Since the female thread portion 29 is formed at two locations in the vertical direction (between the upper end portion 24 and the lower end portion 25), the joint member 31 can be positioned with higher accuracy. Moreover, since the fastening member 50 is fastened by the end surface (for example, the end surface of the 3rd module frame 20c in the connection part 42), the internal thread part 29 is formed so that it may have high mechanical strength. The joint member 31 can be reliably positioned.

  The joint member 31 is fastened to the first wall portion 26 by the fastening member 33b. The fastening member fastening member 33b is, for example, a screw (male screw). The fastening member 33c and the fastening member 33d are configured similarly.

  The upper limit of the plate thickness of the joint member 31 (joint member 30) is defined by the distance between the first wall portion 26 and the female thread portion 29. That is, the joint member 30 is formed of a plate that is thinner than the distance between the first wall portion 26 and the female screw portion 29. The other module frame body 20 (fourth module frame body 20d) at the connecting portion 43 does not have the female screw portion 29. Therefore, when the space is a simple space, the other module frame body 20 is fastened to the third module frame body 20c and extended. Although the positioning of the joint member 31 is unstable, the restricting portion 27 that restricts the position of the joint member 31 is formed. Therefore, the joint member 31 can be easily and highly positioned along the first wall portion 26. Since the joint member 31 is brought into contact with the first wall portion 26 of the fourth module frame 20d by the fastening portion 33a, the mechanical strength can be ensured.

  As described above, in the solar cell module 1 according to the present embodiment, a plurality of module frame bodies 20 (for example, the first module frame body 20a, the second module frame body 20b, the third module frame body 20c, and the fourth module frame body). 20d, fifth module frame 20e) (for example, a set of third module frame 20c and fourth module frame 20d, or a set of fourth module frame 20d and fifth module frame 20e) ) Is the module frame 20 according to the present embodiment, and is a connecting portion 40 formed by being connected to each other (for example, a connecting portion 43 in which the third module frame 20c and the fourth module frame 20d are connected). , An internal angle (for example, an internal angle θ at the connecting portion 43) in plan view of the connecting portion 44 where the fourth module frame 20 d and the fifth module frame 20 e are connected. Interior angle θ4 at the connecting portion 44) are different angle and 90 degrees.

  Therefore, the solar cell module 1 according to the present embodiment has the module frame body 20 according to the present embodiment when the internal angle in a plan view of the connecting portions 40 that are connected to each other is different from 90 degrees. Therefore, even when the solar cell module body 10 is a polygon other than a rectangle, the positioning accuracy and mechanical strength of the connecting portion 40 between the module frame bodies 20 are ensured and the reliability is improved. The installation location can be used effectively.

  In addition, since the shape of the bending part of the joint member 30 becomes closer to a straight line when the module frame 20 is applied when the inner angle exceeds 90 degrees, the strength of the joint member 30 can be reliably maintained. Is preferably applied when the angle exceeds 90 degrees.

  In the module frame 20 according to the present embodiment, the state applied when the inner angle is different from 90 degrees is illustrated, but the module frame 20 has a size of the inner angle formed by connecting the module frame 20. The present invention can also be applied to the case of 90 degrees (in the present embodiment, the connecting portion 40 corresponding to the inner angle θ1, the inner angle θ2, and the inner angle θ5).

  In addition, the solar cell module 1 according to the present embodiment can be defined by a cross section of the module frame 20 in addition to the definition in a plan view.

  That is, the solar cell module 1 according to the present embodiment includes a solar cell module body 10 including a cell region 12 in which the solar cells 11 are arranged and an outer peripheral region 13 arranged in the outer periphery of the cell region 11, and a solar cell module.

There are multiple types.

  Therefore, the solar cell module 1 according to the present invention has a plurality of types of cross-sectional shapes in the direction perpendicular to the length direction of the module frame 20, so that the solar cell module body 10 is a polygon other than a rectangle. Even in such a case, since the positioning accuracy and mechanical strength of the connecting portion between the module frame bodies 20 are ensured and the reliability is improved, the installation location can be used effectively.
