Description

The present invention relates to a solar cell panel laying structure capable of efficiently discharging heat from a space on the back surface side of a solar cell module to prevent a decrease in power generation efficiency of the solar cell .

In recent years, in order to build a society (low carbon society) that emits less carbon dioxide (CO ₂ ) among the greenhouse gases that are the cause for the purpose of alleviating global warming, resources such as conventional petroleum and coal There is a growing social momentum to disseminate renewable energy using sunlight instead of energy that relies on In addition, a mechanism has also been established in which governments and local governments actively subsidize the demand for introducing solar cell modules, and power companies buy surplus power.

In a solar cell module that efficiently uses sunlight, it is known that the power generation efficiency of the solar cell decreases when the temperature on the back surface becomes high.
Therefore, as shown in Patent Document 1, a plurality of "holes" are opened in all of the frame members 2 positioned at the peripheral portion of the solar cell module 1 to form the communication portion 3, and the back side of the solar cell module 1 It has been proposed that the temperature rise be suppressed by communicating the space in the above with each communicating portion 3.

However, in the structure described in Patent Document 1, the air flowing in from the “hole” on the eaves tip side, or from the “hole” on the side, or from between the roofing 7 and the cross rail 4 is directed toward the ridge direction. Although they flow, they can not be discharged sufficiently because they can be discharged only at the uppermost part, ie, the ridge side of a plurality of installed solar cells.
In addition, since the exhaust is affected by the inflow of air, if the wind speed is weak or the inflow is small (small), the amount of exhaust is also small, sufficient exhaust can not be performed, and a large amount of heat is not It stagnated inside.
Furthermore, since "a hole" is formed in all the frame members 2 of the eaves ridge direction and the left-right direction, there existed a possibility that sufficient intensity | strength could not be obtained.

Therefore, the present invention aims to provide a solar cell panel laying structure capable of efficiently discharging heat from the space on the back surface side of the solar cell module to prevent a decrease in the power generation efficiency of the solar cell. .

The present invention has been proposed in view of the above, and has a laying structure in which a solar cell panel having a frame disposed at the periphery of the solar cell module is laid on a roof, wherein the frame is the solar cell module The upper side frame, the lower side frame, and the left and right side frames of the flow direction of the roof surface arranged on the four sides of the upper side frame, the lower side frame, the left and right side frames of the flow direction of the roof surface are respectively The solar cell module has a supporting portion for supporting the side edge and a side surface portion depending downward, and the side surface portions of the upper frame and the lower side frame in the flow direction of the roof surface are lower than the side surfaces of the left and right side frames the adjacent solar cell panel, the upright portion to the upper frame projecting upwardly together with the positions the upper frame of the flow direction of the roof surface in water lower in spaced portion disposed in spaced-like laying in In the laying structure of the solar cell panel characterized by having been provided That.

In the installation structure of the solar cell panel of the present invention, the air (heat amount) on the back surface side of the solar cell module is lower than the side surface of the frame forming the other side at least at the side forming the other side. Since the air can be discharged from the lower side of the frame and the air on the back side can be easily discharged, it is possible to suppress the temperature rise of the solar cell and to prevent the reduction of the power generation efficiency. Further, the adjacent solar cell panels are disposed in a separated manner, and the frame is provided with a side surface portion lower than the side surface portion of the frame forming the other side on the water lower side in the separated portion. With respect to the blowing air flowing on the surface of the solar cell panel, a decompression space is formed on the downwind of the frame, and the air on the back side can be discharged so as to be sucked out. Furthermore, since the side surface portion of the frame forming at least one side is lower than the side surface portion of the frame forming the other side, and at least a part of the frame is provided with a rising portion projecting upward, the solar cell panel In order to further guide the blowing air flowing on the front side upward, a large decompression space is formed downwind of the rising portion, and the air on the back side can be more easily discharged so as to absorb the air on the back side more strongly.

(A)-(c) It is sectional drawing which shows the example of arrangement | positioning of the solar cell panel in this invention.

In the solar cell panel of the present invention, a frame is disposed at the periphery of the solar cell module, and the frame comprises a support portion for supporting the side edge of the solar cell module and a side portion, at least the side portion It is characterized in that one side is lower than the side surface of the other side.
The solar cell panel laying structure of the present invention is a laying structure in which the solar cell panel is laid on a base, and adjacent solar cell panels are disposed in a separated manner, A low side portion is located on the windward side and laid.

The solar cell module used in the present invention may be a module obtained by laminating a solar cell of a crystal system or the like on glass or the like, or it may be a thin film of an amorphous or the like. It may be integrated into a metal plate or the like as a base material to form a sheet (plate) or a board.
Although the single sided light receiving type is generally used as the solar battery cell, a double sided light receiving type may be used to increase the amount of power generation. In this case, if a reflecting portion is provided below the solar cell module Good.
Further, the frame includes an upper frame, a lower frame, and left and right side frames disposed on four sides of the solar cell module, and each frame is a support portion for supporting the periphery of the solar cell module; And a downwardly depending side surface portion.
And the said frame was distribute | arranged to the peripheral edge of the said solar cell module, and it was set as the solar cell panel.

The feature of the solar cell panel of the present invention is that at least one side of the side face of the frame is lower than the side face of the other side (= smaller height width), and not limited to only one side, two sides, three sides May be low. As one side to be a low side surface portion like a solar cell panel in the illustrated embodiment described later, the leeward side is preferable, but the wind side opposite to it may not necessarily be the low side surface portion.
An open portion is formed below the side surface portion (lower side surface portion) which is lower than the side surface portion of the other side in this manner. And since the formed opening part is formed between a low side part and a foundation in the state of arrangement, it becomes an exhaust port of air from the space by the side of the back of a solar cell module. Moreover, by setting it as a low side part, a side part does not stop the flow of back surface air (it makes it stay).
Generally, in order to connect adjacent solar cell modules, processing such as cutting out a part of a frame is performed to pass a cable, but when sufficient space is not formed on the back surface of the solar cell panel It is also possible to use this opening.

  Further, the support portion of the solar cell panel in the present invention is a portion for supporting the side edge of the solar cell module, and may be substantially U-shaped or substantially L-shaped (inverted L-shaped). In the case of the substantially U-shape, the support portion holds the edge of the solar cell panel, and in the case of the substantially L-shape, the edge of the solar cell panel is supported in a mounting manner It becomes. Therefore, in the latter mode, it is preferable to press from above using a pressing member or the like to hold the edge of the solar cell panel in a sandwiching manner.

As described above, the object of the present invention is to efficiently dissipate heat from the space on the back side of the solar cell module to prevent a decrease in the power generation efficiency of the solar cell, and the space on the back side is It may be formed between the solar cell panel and the base, and the height width may be partially increased by the shape of the base such as an exterior structure having a wave or rising portion or the like. Alternatively, the solar cell panel may be laid directly on the substantially flat base to form a substantially uniform thin space surrounded by the solar cell module and the peripheral frame, or the carrying-out fitting or mounting member, It may be formed between the base attached with supporting members such as horizontal bars, vertical bars and the like and the solar cell panel.
In any back side space, the air (heat quantity) heated in the space tries to move to a higher position, so at least one side is a low side as described above. Thereby, the air (heat quantity) warmed in the space can be released from the opening to the outside. In addition, the inflow of air from the outside into the space is performed from any direction around, except for the aspect of laying the solar cell panel directly on the above-described substantially flat base. In a mode in which the solar cell panel is directly laid on a substantially flat base, it is desirable to allow air to flow with the side portions on the two sides as the low side portions.
Such a back side space may be continuous to the eaves ridge direction or the direction toward the girder, or both of them, or may be independent.

Further, in the solar cell panel laying structure according to the present invention, the above-mentioned “adjacent solar cell panels are disposed in a separated manner” configuration means that an open portion with a constant gap is provided between adjacent solar cell panels. It is meant to form.
As shown in the illustrated embodiment to be described later, a mounting member capable of regulating the position of the end of the solar cell panel and holding the distance between the open portions is fixed in advance to the ground, and the solar cell panel is disposed on this mounting member By doing this, it may be possible to form open portions at regular intervals.
In addition, “If the low side portion is located on the windward side of the separated portion and laid,” for example, in the case of a general roof slope, it is completely reversed from the ridge side which is the flow direction of the roof surface to the eaves side. In addition, since it is assumed that the blowing wind blows up from the eaves side to the ridge side, the low side surface portion is positioned on the upwind side, that is, the water lower side in the separated portion.

The low side surface portion may be provided with a rising portion projecting upward. The rising portions need not be provided on all the low side portions, and may be provided appropriately in consideration of the flow of wind. Further, the standing portion may be provided over the entire length of the side of the solar cell module or may be partially provided. Furthermore, the rising portion may be substantially perpendicular to the surface of the solar cell, or may be inclined inwardly or outwardly. In addition, the rising portion may be a substantially flat rising piece, an arc (curved surface) or a stepped rising piece.
In addition, the rising portion may be integrally molded to the low side surface portion itself, or may be separately attached as an external member or previously integrated into an attachment member etc. It may be attached indirectly to the base by fastening, fitting, engaging, adhering or combining these with screws, bolts, nuts etc., or by co-tightening a separate standing up part with the mounting member etc. It is also good.

  Then, by providing the rising portion on the low side surface, the air hitting the rising portion causes turbulent flow upward, and the upper end of the rising portion is depressurized, so the air on the back surface space of the solar cell panel is low on side surface The function of sucking air from the opening part formed below the surface to the surface side is performed, and the flow of air in the back space is significantly accelerated, and the decrease in the power generation efficiency is prevented by suppressing the temperature generated by the solar cell itself. it can.

In the solar cell panel laying structure of the present invention, the solar cell panel of the above-mentioned constitution may be laid on the base shown below, or may be attached to various walls.
The base used in the present invention is a known roof such as existing tiles, slate, metal, etc., or a roof made of tiles, slate, metal, etc. to be newly installed. It is desirable to have one, and it does not matter what the specification is, for example, a waterproof layer made of a waterproof sheet such as polyvinyl chloride may be used. In addition, the existing or new roof made of metal or the like may be of any type such as horizontal, vertical (such as tiled, smooth), or folded plate.
The solar cell panel may be directly attached to the members constituting the base, or the solar cell panel may be attached via various mounting brackets, mounting members, mounting brackets such as lifting brackets, horizontal bars, vertical bars, etc. You may That is, the base in the present invention also includes the above-described base or a mounting material attached thereto.

In addition, the cable 101 of the solar cell module 10 can be housed in the shallow saucer-like inner side of the landing portions 123 and 133 so as not to drop.

  In the laying structure formed by laying the solar cell panel 1 having such a configuration on the base 30, adjacent solar cell panels 1 and 1 are disposed in a separated manner, and the wind of the separated portion (open portion 15) The low side surface portion 112 is located on the upper side and laid. That is, the opening part 15 is the arrangement | positioning space | interval of the solar cell panels 1 and 1 adjacent to a flow direction.

In the first embodiment, the rising portion 2 is provided on the windward side of the opening portion (separating portion) 15.
More specifically, the lower end of the upright piece (portion) 2 is fitted and integrally fixed to the upper frame 11 of the solar cell panel 1 disposed on the water side of the open portion 15.
Further, the rising piece (portion) 2 is formed such that the lower end thereof is substantially vertical and the upper part thereof is inclined upward to the water.
Then, the upper frame 11 is provided with a mounting groove 113 which protrudes in a substantially L shape to the upper side of the water outside the side surface portion 112 and opens upward, and the lower end of the rising piece (portion) 2 has a substantially hook-like engagement. Since the toe is provided, it can be elastically fitted and fixed from above.

As described above, the solar cell panel 1 is laid in a state in which the bottom portions 123 and 133 provided on the side frames 12 and 13 are received on the receiving flange 41 of the lifting bracket 4, but fixing is The side frames 12 and 13 are pressed and held from above by a pressing member 5A.

It is fixed.

In order to construct the solar cell panel 1 of the first embodiment, first, the takeout metal fitting 4 is attached to a predetermined position of the folded plate roof 30. With this predetermined position, when the long side of the solar cell panel 1 is supported at three points, the position that is most mechanically stable is selected.
In this state, the solar cell panel 1 is disposed, but at this time, as shown in the drawing, the upright pieces 2 are disposed in a state where they are not integrally attached. Specifically, the bottom portions 123 and 133 provided on the side frames 12 and 13 of the solar cell panel 1 are disposed to be supported on the receiving flange 41 of the lifting bracket 4.

A convex fixed receiving portion 62 is formed between the left and right receiving portions 61, 61, and a hole 621 through which the vertical bolt 4C of the lifting metal fitting 4 is inserted is formed substantially at the center of the fixed receiving portion 62. It is done. Further, the step 63 at the boundary between the receiving portion 61 and the fixed receiving portion 62 plays a role of restricting the position when the solar cell panel 1 is disposed, and also plays a role of preventing a shift after the disposition.

  In addition, as shown in FIG. 5 (d), the holding / cum-mounting material 7 in the third embodiment has a flange-like end edge bent upward and downward facing the end edge of the solar cell panel 1 as shown in an enlarged manner. A flat plate portion 72 having a substantially flat shape is formed between the pressing portions 71 and 71 which are pressed from above, and a hole 721 through which the vertical bolt 4C of the lifting metal fitting 4 is inserted is formed substantially at the center of the flat plate portion 72. It is done. Furthermore, receiving piece portions 722 and 722 are formed by bending the left and right side edges of the flat plate portion 72 downward and having the lower end seated on the fixed receiving portion 62 of the receiving metal fitting 6. Further, on the left and right of one (the front side in the drawing) of the pressing portion 71, mounting portions 73, 73, which are inclined rising pieces, are provided.

And a mounting groove 24 which is open at the lower side on the back surface side is formed across the length direction. The mounting groove 24 can be engaged with the upper end of the mounting portion 73 of the pressing member 7, and is bridged over the mounting portions 73, 73 of the pressing members and mounting members 7, 7 adjacent to the left and right to make upstanding pieces 2D. Attach.

In order to construct the solar cell panel 1 of the third embodiment, first, the takeout metal fitting 4 is attached to a predetermined position of the folded plate roof 30, and subsequently, the receiving metal fitting 6 of the above configuration is fixed in a laminated manner. In addition, this predetermined position refers to the square part of the solar cell panel 1 to lay. Further, since the vertical bolt 4C of the takeout fitting 4 may be inserted into the hole 621 of the receiving fitting 6, the receiving fitting 6 can be disposed at an appropriate position extremely easily.
Although the solar cell panel 1 is disposed in this state, it may be disposed so that the edge of the solar cell panel 1 abuts on the step 63 of the bracket 6, and the solar cell panel 1 can be easily disposed. it can.
Next, the holding material and mounting material 7 having the above-described configuration are overlapped and fixed on the receiving metal fitting 6. Similarly to the arrangement of the receiving metal fitting 6, the vertical bolt 4C of the takeout metal fitting 4 is used as a holding material. Since it is sufficient to insert the hole 721 of the mounting material 7, the holding material and mounting material 6 can be disposed at an appropriate position extremely easily. Incidentally, needless to say, when arranging the pressing member-cum-mounting material 7, the pressing portion 71 is disposed so as to press the square edge of the solar cell panel 1.
After that, as described above, the mounting grooves 73 of the upright piece 2D are engaged so as to be engaged with the mounting portions 73, 73 of the pressing members and the mounting members 7, 7 adjacent to the left and right.

Also in the third embodiment, the same effects as in the first and second embodiments can be obtained.
In addition, the takeout metal fitting 4 is disposed in the square of the solar cell panel 1 disposed as described in the above-described installation procedure, and then the receiving metal fitting 6, then the solar cell panel 1, and the pressing member and mounting material 7 In this order, since each member is regulated in position, the mounting operation can be easily performed.
Furthermore, as shown in FIG. 5 (b), in the square of a single solar cell panel 1, units each including the takeout metal fitting 4, the fitting metal fitting 6 and the holding material and mounting material 7 are arranged. The erecting pieces 2D are bridged over (the attaching portions 73, 73 of the pressing members and attaching members 7, 7 of the unit), and one unit is four adjacent to the flow direction and the lateral direction (the direction of the girder) Since they are disposed across the solar cell panel 1, it can be said that the structure has a relatively small number of members, that is, a structure attached with a small number of points.

6 (a) to 6 (c) show typical arrangement examples of the solar cell panels 1 in the present invention, where the right side of the drawing is the water upper side, the left side is the water lower side, and from left to right It shows the case where it is assumed that the wind blows toward the head, and the flow of air is indicated by a thick white arrow.
FIG. 6 (a) is an example in which the respective solar cell panels 1 are disposed substantially in parallel, and the first embodiment corresponds to an example thereof, but it flows on the surface of the solar cell panel 1 at the standing portion 2 By forming turbulence in the air flow, the air 16 on the back side is discharged from the open portion 15 close to the rising portion 2.
FIG. 6 (b) shows an example in which each solar cell panel 1 is disposed in an inclined manner to raise the upper side in the flow direction, and the third embodiment corresponds to that example, but in the space 16 on the back side, It flows obliquely on the back surface of the solar cell panel 1 and is discharged from the open portion 15.
In FIG. 6 (c), the solar cell panels 1 are substantially parallel as in the case of FIG. 6 (a), but the sun is not provided with the standing portion 2 on the water side of the solar cell panel 1 having the standing portion 2. This is an example in which the battery panel 1 is disposed close to each other, and the flow of air flows as if the length of the solar cell panel 1 is doubled, and the air 16 on the back side is the same as FIG. 6 (a). Is discharged from the open portion 15 close to the rising portion 2. Thus, the rising portions 2 may be provided in all the open portions 16 or may be partially provided.
