Description

[Technical Field]

[0001] The present invention relates to an installation structure for a photoelectric conversion module and an installation method for a photoelectric conversion module. [Background technology]

[0002] In recent years, flexible solar cell modules (photovoltaic conversion modules) have been attracting attention (see Patent Document 1 below). In Patent Document 1, the photovoltaic conversion module is adhered to an installation surface (a portion to be installed) using double-sided tape and an adhesive (adhesive). The adhesive is provided along the periphery of the photovoltaic conversion module. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7302921 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, the adhesive is provided around the entire periphery of the rear surface of the photovoltaic conversion module. Therefore, a space may be created between the rear surface of the photovoltaic conversion module, the installation surface, and the adhesive. If a pressure difference occurs between the space and the atmosphere due to a temperature change or the like, the photovoltaic conversion module may bend relative to the installation surface. This bending of the photovoltaic conversion module may place a load on the installation surface and the adhesive.

[0005] Therefore, there is a need for a photovoltaic conversion module installation structure and a photovoltaic conversion module installation method that can reduce the load on the installation target and adhesive. [Means for solving the problem]

[0006] According to one embodiment, the photovoltaic conversion module mounting structure includes a mounting base, a photovoltaic conversion module, and an adhesive that bonds the photovoltaic conversion module and the mounting base. The adhesive is provided along the outer periphery of the photovoltaic conversion module. A non-adhesive portion where the adhesive is not provided is located at at least one location on the outer periphery of the photovoltaic conversion module.

[0007] A method for installing a photovoltaic conversion module according to one embodiment includes the steps of providing an adhesive material along an outer periphery of the photovoltaic conversion module to bond the photovoltaic conversion module to a mounting portion, and bonding the photovoltaic conversion module to the mounting portion with the adhesive material, wherein a non-adhesive portion where the adhesive material is not provided is disposed at at least one location on the outer periphery of the photovoltaic conversion module. [Effects of the Invention]

[0008] According to the above aspect, it is possible to provide a photovoltaic conversion module installation structure and a photovoltaic conversion module installation method that can reduce the load on the installation portion and adhesive. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments will be described with reference to the drawings. In the following drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratios of the dimensions may differ from those of the actual parts.

[0011] [First embodiment] An installation structure for a photovoltaic conversion module according to a first embodiment will be described with reference to FIGS. 1 to 4. FIG. 1 is a schematic top view of the installation structure for a photovoltaic conversion module according to the first embodiment. FIG. 2 is a schematic side view of the installation structure for a photovoltaic conversion module as seen from the direction of arrow 2A in FIGS. 1 and 3. FIG. 3 is a schematic side view of the installation structure for a photovoltaic conversion module as seen from the direction of arrow 3A in FIG. 1. FIG. 4 is a schematic view showing adhesive regions and non-adhesive regions provided on the photovoltaic conversion module according to the first embodiment. For convenience of explanation, the installation portion 200 is not shown in FIG. 4.

[0012] The installation structure for the photoelectric conversion module includes a photoelectric conversion module 100, an installation portion 200, and an adhesive 300. The installation portion 200 is the portion on which the photoelectric conversion module 100 is installed. The installation portion 200 is not particularly limited, and may be, for example, the outer surface of a building or a mobile object. The outer surface of a building may be, for example, the roof or outer wall of the building. The mobile object may be, for example, a vehicle, a ship, an aircraft, or a rocket.

[0013] The installation portion 200 may have a flat surface or a curved surface. When the installation portion 200 has a curved surface, it is preferable that the photoelectric conversion module 100 is configured to be bendable. Furthermore, the surface of the installation portion 200, i.e., the surface to which the photoelectric conversion module 100 is adhered, may be a surface parallel to a horizontal plane or may be inclined with respect to the horizontal plane.

[0014] The photoelectric conversion module 100 is a module that has the function of converting optical energy into electrical energy and vice versa. Preferably, the photoelectric conversion module 100 is configured to be bendable.

[0015] In this specification, the "front side" of the photovoltaic conversion module 100 refers to the side that receives light or the side that emits light. When the photovoltaic conversion module is a solar cell module, the "front side" corresponds to the light-receiving side that receives sunlight. Furthermore, the "rear side" refers to the side opposite to the "front side."

[0016] The photoelectric conversion module 100 may have one or more photoelectric conversion elements 10 and a sheet-like or plate-like base 20. The photoelectric conversion elements 10 are elements that convert light energy into electrical energy and vice versa. The photoelectric conversion elements 10 are provided in or on the base 20.

[0017] When the photoelectric conversion module 100 includes a plurality of photoelectric conversion elements 10, the plurality of photoelectric conversion elements 10 may be arranged in at least one direction, preferably in a lattice pattern. In this case, the plurality of photoelectric conversion elements 10 may be electrically connected to each other in series and / or parallel.

[0018] The configuration of each photoelectric conversion element 10 is not particularly limited. The photoelectric conversion element 10 may be a so-called silicon-based, compound semiconductor-based, or chemical-based photoelectric conversion element. Examples of silicon-based photoelectric conversion elements include single-crystal, polycrystalline, and thin-film photoelectric conversion elements. Examples of compound semiconductor-based photoelectric conversion elements include III-V, CIGS, or CdTe-based photoelectric conversion elements. Examples of chemical-based photoelectric conversion elements include dye-sensitized or organic semiconductor-based photoelectric conversion elements.

[0019] There are no particular limitations on the shape of the base 20 when viewed from a direction perpendicular to the surface of the photoelectric conversion module 100. When viewed from a direction perpendicular to the surface of the photoelectric conversion module 100, the shape of the base 20 may be, for example, a square or rectangular shape.

[0020] When viewed from a direction perpendicular to the surface of the photoelectric conversion module 100, the base 20 may be wider than the area where one or more photoelectric conversion elements 10 are provided. In other words, each end side of the base 20 may have an area where no photoelectric conversion element 10 is formed.

[0021] The photovoltaic conversion module 100 may have a junction box 30 arranged on at least one side of the photovoltaic conversion module 100. The junction box 30 is a case that houses external terminals that electrically connect the photovoltaic conversion module 100 to external devices. Wiring (not shown) drawn from one or more photovoltaic conversion elements 10 may be gathered in the junction box 30.

[0022] The junction box 30 may be provided on an edge of the base 20. Specifically, the junction box 30 may be provided on the surface side of the edge of the base 20, in an area where no photoelectric conversion element 10 is provided (see FIG. 1). In the embodiment shown in FIG. 1, multiple junction boxes 30 are provided on the surface side of one edge of the base 20.

[0023] The adhesive 300 is provided between the photoelectric conversion module 100 and the installation portion 200. The adhesive 300 bonds the photoelectric conversion module 100 and the installation portion 200 to each other.

[0024] The adhesive 300 may include at least one type of adhesive. In the embodiment shown in Figure 4, the adhesive 300 includes two types of adhesive: a first adhesive 310 and a second adhesive 320. The first adhesive 310 may be a double-sided tape, or a one-component or two-component adhesive. The second adhesive 320 may be a double-sided tape, or a one-component or two-component adhesive.

[0025] Preferably, first adhesive 310 is a double-sided tape, and second adhesive 320 is a one-component or two-component adhesive. Thus, first adhesive 310 is used to temporarily fasten photovoltaic conversion module 100 and installation portion 200 together until second adhesive 320 firmly bonds photovoltaic conversion module 100 and installation portion 200 together.

[0026] The first adhesive 310 and the second adhesive 320 may be disposed adjacent to each other, as shown in Figure 4. Alternatively, the first adhesive 310 and the second adhesive 320 may be disposed not adjacent to each other.

[0027] It should be noted that in the following description, when a plurality of adhesive materials 310, 320 are provided, adhesive material 300 is used as a general term including the plurality of adhesive materials 310, 320.

[0028] The adhesive 300 may be provided along the outer periphery of the back side of the photovoltaic conversion module 100. The adhesive 300 is preferably arranged along the outer periphery of the photovoltaic conversion module 100 over a length that is, for example, 65% or more, 70% or more, 75% or more, or 80% or more of the total length of the outer periphery of the photovoltaic conversion module 100. This ensures adhesive strength between the photovoltaic conversion module 100 and the installation portion 200.

[0029] A non-adhesive portion 380 where no adhesive material 300 is provided is disposed at at least one location on the outer periphery of the photovoltaic conversion module 100. In the first embodiment, the non-adhesive portion 380 is disposed at one location on the outer periphery of the photovoltaic conversion module 100.

[0030] The space surrounded by the back surface of the photovoltaic conversion module 100, the installation portion 200, and the adhesive 300 is fluidly connected to the atmosphere (atmosphere) through the non-adhesive portion 380. Therefore, a pressure difference is unlikely to occur between the atmosphere and the space between the back surface of the photovoltaic conversion module 100 and the installation portion 200. This prevents the photovoltaic conversion module 100 from bending relative to the installation portion 200, thereby reducing the load on the installation portion 200 and the adhesive 300.

[0031] Since the space between the rear surface side of the photovoltaic conversion module 100 and the installation portion 200 is fluidly connected to the atmosphere, condensation is unlikely to occur in the portion facing this space even if the temperature drops suddenly.

[0032] 4, the non-adhesive portions 380 are preferably provided at positions that avoid the corners of the photovoltaic conversion module 100. In other words, the positions corresponding to the corners of the photovoltaic conversion module 100 may be adhered with the adhesive material 300. In particular, if the photovoltaic conversion module 100 is bendable, the positions corresponding to the corners of the photovoltaic conversion module 100 are preferably adhered with the adhesive material 300. This makes it possible to prevent the corners of the photovoltaic conversion module 100 from curling up.

[0033] The surface of the installation portion 200 may be inclined with respect to the horizontal plane H, as shown in Fig. 3, for example. In this case, it is preferable that the non-adhesive portion 380 be provided only on a side of the periphery of the photoelectric conversion module 100 other than the side 22 on the water side in the inclined direction of the installation portion 200. In other words, it is preferable that the entire side 22 on the water side in the inclined direction of the installation portion 200 of the periphery of the photoelectric conversion module 100 is adhered with the adhesive 300. This makes it possible to prevent liquid such as rainwater from running down the surface of the installation portion 200 and entering the space between the photoelectric conversion module 100 and the installation portion 200.

[0034] When the surface of the installation portion 200 is inclined with respect to the horizontal plane H, the non-adhesive portion 380 is preferably provided on one side 21 of the outer periphery of the photoelectric conversion module 100 that is below the water in the inclined direction of the installation portion 200. This allows the liquid to be discharged to the outside through the non-adhesive portion 380 even if liquid accumulates in the space between the photoelectric conversion module 100 and the installation portion 200 for some reason.

[0035] In the first embodiment, the non-adhesive portion 380 may be provided at a position away from the junction box 30 when viewed from a direction intersecting the surface of the photovoltaic conversion module 100. In the example shown in Fig. 4, the non-adhesive portion 380 is provided on a side of the photovoltaic conversion module 100 that is different from the side on which the junction box 30 is provided. In other words, the region of the photovoltaic conversion module 100 that overlaps with the junction box 30 when viewed from a direction intersecting the surface of the photovoltaic conversion module 100 is adhered to the installation surface 200 by the adhesive 300.

[0036] As described above, the junction box 30 corresponds to the location where wiring (not shown) drawn from one or more photoelectric conversion elements 10 gather. When the area of ​​the junction box 30 is adhered to the installation surface 200, the area of ​​the junction box 30 of the photoelectric conversion module 100 hardly repeatedly bends due to temperature changes, etc. Therefore, the reliability of the electrical connection can be improved.

[0037] Next, a method for installing a photovoltaic conversion module that provides the above-mentioned installation structure for the photovoltaic conversion module will be described. First, the photovoltaic conversion module 100 is prepared. The configuration of the photovoltaic conversion module 100 is as described above.

[0038] Next, a step is performed in which an adhesive 300 that bonds the photovoltaic conversion module 100 and the installation portion 200 to each other is provided along the outer periphery of the photovoltaic conversion module 100. Before bonding the photovoltaic conversion module 100 and the installation portion 200 to each other, the adhesive 300 may be provided on the back side of the photovoltaic conversion module 100 or on the surface of the installation portion 200.

[0039] The installation pattern of adhesive 300, i.e., the pattern of adhesive portions and non-adhesive portions 380, is as described above. That is, adhesive 300 and non-adhesive portions 380 may be formed in the above-described pattern described in the installation structure of the photovoltaic conversion module.

[0040] As described above, the adhesive material 300 may include at least one type of adhesive. Preferably, the adhesive material 300 includes multiple types of adhesive. In this case, the adhesive material 300 may include two types of adhesive, a first adhesive material 310 and a second adhesive material 320. The types of the first adhesive material 310 and the second adhesive material 320 are as described above.

[0041] More preferably, the first adhesive 310 is a double-sided tape, and the second adhesive 320 is a one-component or two-component adhesive. Thus, the first adhesive 310 is used to temporarily fasten the photovoltaic conversion module 100 and the installation portion 200 together until the second adhesive 320 firmly bonds the photovoltaic conversion module 100 and the installation portion 200 together.

[0042] Next, the photovoltaic conversion module 100 and the installation portion 200 are bonded to each other using adhesive 300. In this way, the above-described installation structure for the photovoltaic conversion module is obtained.

[0043] [Second embodiment] The installation structure of a photovoltaic conversion module according to the second embodiment will be described with reference to FIG. 5. FIG. 5 is a schematic diagram showing adhesive regions and non-adhesive regions provided on a photovoltaic conversion module according to the second embodiment. For convenience of explanation, the installation portion 200 is not shown in FIG. 5. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals. Please note that the description of the same components as those in the first embodiment may be omitted.

[0044] In the photovoltaic conversion module installation structure according to the second embodiment, the configurations of the photovoltaic conversion module 100 and the installation portion 200 are the same as those in the first embodiment. In the second embodiment, the area where the adhesive 300 is provided and the area of ​​the non-adhesive portion 380 are different from those in the first embodiment.

[0045] The adhesive 300 may be provided along the outer periphery of the photovoltaic conversion module 100. In the second embodiment, the non-adhesive portions 380 are arranged in at least two locations on the outer periphery of the photovoltaic conversion module 100. In the example shown in Fig. 5, the non-adhesive portions 380 are arranged on each end side of the photovoltaic conversion module 100. This makes it easier to eliminate the temperature difference that occurs between the atmosphere and the space between the back side of the photovoltaic conversion module 100 and the installation portion 200. Therefore, condensation is less likely to occur.

[0046] Instead of the example shown in Figure 5, if the surface of the installation portion 200 is inclined with respect to the horizontal plane H, the entire above-water side 22 of the outer periphery of the photoelectric conversion module 100 in the inclined direction of the installation portion 200 may be adhered with adhesive 300.

[0047] [Third embodiment] The installation structure of a photovoltaic conversion module according to the third embodiment will be described with reference to FIG. 6. FIG. 6 is a schematic diagram showing adhesive regions and non-adhesive regions provided on a photovoltaic conversion module according to the third embodiment. For convenience of explanation, the installation portion 200 is not shown in FIG. 6. Also, for convenience of explanation, the position of a junction box 30 provided on the front side of the photovoltaic conversion module is indicated by a dotted line in FIG. 6. In the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals. Please note that the description of the same components as those in the first embodiment may be omitted.

[0048] In the photovoltaic conversion module installation structure according to the third embodiment, the configurations of the photovoltaic conversion module 100 and the installation portion 200 are the same as those in the first embodiment. In the third embodiment, the area where the adhesive 300 is provided and the area of ​​the non-adhesive portion 380 are different from those in the first embodiment.

[0049] The adhesive 300 may be provided along the outer periphery of the photovoltaic conversion module 100. In the third embodiment, the non-adhesive portions 380 are provided at at least two locations on the outer periphery of the photovoltaic conversion module 100. Specifically, the non-adhesive portions 380 are provided on a pair of opposing sides on the outer periphery of the photovoltaic conversion module 100. In the example shown in FIG. 6, the non-adhesive portions 380 are provided on each end side of the photovoltaic conversion module 100.

[0050] In the third embodiment, as shown in FIG. 6, a pair of non-adhesive portions 380 provided on a pair of opposing sides are positioned at positions offset from each other in the extension direction of the pair of sides. That is, the non-adhesive portion 380 provided on the upper side in FIG. 6 is positioned offset laterally (in the direction in which the upper sides extend) relative to the non-adhesive portion 380 provided on the lower side in FIG. 6. As a result, for example, when air flows in through the non-adhesive portion 380 on the upper side and is discharged through the non-adhesive portion 380 on the lower side, the air flows in a swirling path between the photovoltaic conversion module 100 and the installation portion 200. This makes it easier to suppress excessive temperature rise in the space between the photovoltaic conversion module 100 and the installation portion 200. Furthermore, since the temperature distribution throughout the photovoltaic conversion module 100 is easily uniform, the temperature difference between each photovoltaic conversion element 10 is reduced. Therefore, it is also possible to suppress a decrease in the overall power generation efficiency of the photovoltaic conversion module 100 due to uneven temperature distribution.

[0051] In the example shown in Fig. 6, the non-adhesive portion 380 provided on the left side in Fig. 6 is shifted in the up-down direction (the direction in which the left and right sides extend) relative to the non-adhesive portion 380 provided on the right side in Fig. 6. Alternatively, the non-adhesive portion 380 may be provided on only a pair of opposing sides, i.e., only two sides.

[0052] 6, in the third embodiment, the non-adhesive portion 380 is disposed on the edge of the photovoltaic conversion module 100 where the junction box 30 is provided. Even in this case, the non-adhesive portion 380 may be provided at a position away from the junction box 30 when viewed from a direction intersecting the surface of the photovoltaic conversion module 100. This makes it possible to prevent the region of the junction box 30 of the photovoltaic conversion module 100 from repeatedly bending due to temperature changes and the like, as described in the first embodiment. This can improve the reliability of the electrical connection.

[0053] [Fourth embodiment] An installation structure for a photovoltaic conversion module according to a fourth embodiment will be described with reference to FIG. 7. FIG. 7 is a schematic diagram showing adhesive regions and non-adhesive regions provided on a photovoltaic conversion module according to the fourth embodiment. For convenience of explanation, the installation portion 200 is not shown in FIG. 7. Also, for convenience of explanation, the position of the junction box 30 provided on the front side of the photovoltaic conversion module is indicated by a dotted line in FIG. 7. In the fourth embodiment, the same components as those in the first embodiment are assigned the same reference numerals. Please note that explanations of the same components as those in the fourth embodiment may be omitted.

[0054] In the installation structure for a photovoltaic conversion module according to the fourth embodiment, the configurations of the photovoltaic conversion module 100 and the installation portion 200 are the same as those in the first embodiment. In the fourth embodiment, the area where the adhesive 300 is provided and the area of ​​the non-adhesive portion 380 are different from those in the first embodiment.

[0055] The adhesive 300 may be provided along the outer periphery of the photovoltaic conversion module 100. In the third embodiment, the non-adhesive portion 380 is provided at a position overlapping the junction box 30 when viewed from a direction intersecting the surface of the photovoltaic conversion module 100. In the example shown in Fig. 7, the non-adhesive portion 380 is provided at multiple locations corresponding to multiple junction boxes 30.

[0056] The junction box 30 corresponds to a portion of the photovoltaic conversion module 100 at the edge where the junction box 30 is provided that is relatively prone to heat generation. Therefore, when the non-adhesive portion 380 is provided directly below the junction box 30, there is an advantage in that heat from the junction box 30 is easily dissipated.

[0057] 7, the non-adhesive portion 380 is provided only at a position that overlaps the junction box 30 when viewed from a direction intersecting the surface of the photovoltaic conversion module 100. Alternatively, the non-adhesive portion 380 may be provided at a position other than the position that overlaps the junction box 30 when viewed from a direction intersecting the surface of the photovoltaic conversion module 100.

[0058] [Fifth embodiment] The installation structure of a photovoltaic conversion module according to the fifth embodiment will be described with reference to FIG. 8. FIG. 8 is a schematic diagram showing adhesive regions and non-adhesive regions provided on a photovoltaic conversion module according to the fifth embodiment. For convenience of explanation, the installation portion 200 is not shown in FIG. 8. In the fifth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals. Please note that the description of the same components as those in the first embodiment may be omitted.

[0059] In the photovoltaic conversion module installation structure according to the fifth embodiment, the configurations of the photovoltaic conversion module 100 and the installation portion 200 are the same as those in the first embodiment. In the fifth embodiment, the area where the adhesive 300 is provided and the area of ​​the non-adhesive portion 380 are different from those in the first embodiment.

[0060] The adhesive 300 may be provided along the outer periphery of the photovoltaic conversion module 100. In the fifth embodiment, the adhesive 300 is provided over the entirety of two of the four end sides of the photovoltaic conversion module 100. Preferably, the adhesive 300 is provided over the entirety of two relatively long end sides of the four end sides of the photovoltaic conversion module 100. In other words, the non-adhesive portion 380 is provided over almost the entirety of two relatively short end sides of the four end sides of the photovoltaic conversion module 100. However, the corners of the photovoltaic conversion module 100 may be adhered with the adhesive 300.

[0061] In the fifth embodiment, the length of the non-adhesive portion 380 is increased, making it more difficult for a pressure difference and / or a temperature difference to occur between the atmosphere and the space between the back surface side of the photovoltaic conversion module 100 and the installation portion 200. Also, in the fifth embodiment, the adhesive material 300 is provided long in one direction along the two end sides, making it relatively easy to install the adhesive material 300.

[0062] Even in this case, it is preferable that the adhesive 300 be disposed around the periphery of the photovoltaic conversion module 100 over a length that is, for example, 65% or more, 70% or more, 75% or more, or 80% or more of the total length of the periphery of the photovoltaic conversion module 100. This makes it possible to ensure adhesive strength between the photovoltaic conversion module 100 and the installation portion 200.

[0063] [Sixth embodiment] An installation structure for a photovoltaic conversion module according to the sixth embodiment will be described with reference to FIG. 9. FIG. 9 is a schematic diagram showing adhesive regions and non-adhesive regions provided on a photovoltaic conversion module according to the sixth embodiment. For convenience of explanation, the installation portion 200 is not shown in FIG. 9. In the sixth embodiment, the same components as those in the fifth embodiment are denoted by the same reference numerals. Please note that the description of the same components as those in the fifth embodiment may be omitted.

[0064] In the installation structure for a photovoltaic conversion module according to the sixth embodiment, the configurations of the photovoltaic conversion module 100 and the installation portion 200 are the same as those in the first embodiment. In the sixth embodiment, the area where the adhesive 300 is provided and the area of ​​the non-adhesive portion 380 are different from those in the fifth embodiment.

[0065] The adhesive 300 may be provided along the outer periphery of the photovoltaic conversion module 100. In the sixth embodiment, the adhesive 300 is provided over the entire two of the four end sides of the photovoltaic conversion module 100. Preferably, the adhesive 300 is provided over the entire two relatively long end sides of the four end sides of the photovoltaic conversion module 100. Furthermore, the adhesive 300 is also provided over parts of the two relatively short end sides of the four end sides of the photovoltaic conversion module 100. As a result, the non-adhesive portions 380 are provided at multiple locations on each of the two relatively short end sides of the four end sides of the photovoltaic conversion module 100.

[0066] The length of the non-adhesive portion 380 according to the sixth embodiment is shorter than the length of the non-adhesive portion 380 according to the fifth embodiment. Therefore, the adhesive strength between the photovoltaic conversion module 100 and the installation portion 200 can be further ensured.

[0067] [Seventh embodiment] An installation structure for a photovoltaic conversion module according to the seventh embodiment will be described with reference to FIG. 10. FIG. 10 is a schematic diagram showing adhesive regions and non-adhesive regions provided on a photovoltaic conversion module according to the seventh embodiment. For convenience of explanation, the installation portion 200 is not shown in FIG. 10. In the seventh embodiment, the same components as those in the sixth embodiment are denoted by the same reference numerals. Please note that the description of the same components as those in the sixth embodiment may be omitted.

[0068] In the installation structure for a photovoltaic conversion module according to the seventh embodiment, the configurations of the photovoltaic conversion module 100 and the installation portion 200 are the same as those in the first embodiment. In the seventh embodiment, the area where the adhesive 300 is provided and the area of ​​the non-adhesive portion 380 are different from those in the sixth embodiment.

[0069] The adhesive material 300 may be provided along the outer periphery of the photovoltaic conversion module 100. In the seventh embodiment, the adhesive material 300 is provided over two of the four end sides of the photovoltaic conversion module 100. Preferably, the adhesive material 300 is provided over two of the four end sides of the photovoltaic conversion module 100 that are relatively long. Furthermore, the adhesive material 300 is provided at a position between the two relatively long end sides (long sides) of the photovoltaic conversion module 100, extending generally parallel to the long sides.

[0070] As a result, in comparison with the sixth embodiment, in the seventh embodiment, the adhesive force between the photoelectric conversion module 100 and the installation portion 200 can be more securely secured.

[0071] Furthermore, in the seventh embodiment, since the multiple adhesive materials 300 are arranged so as to extend in the same direction, there is also the advantage that the step of applying the adhesive material 300 can be easily carried out.

[0072] [Eighth embodiment] An installation structure for a photovoltaic conversion module according to the eighth embodiment will be described with reference to FIG. 11. FIG. 11 is a schematic diagram showing adhesive regions and non-adhesive regions provided on a photovoltaic conversion module according to the eighth embodiment. For convenience of explanation, the installation portion 200 is not shown in FIG. 11. In the eighth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals. Please note that the description of the same components as those in the first embodiment may be omitted.

[0073] In the installation structure for a photovoltaic conversion module according to the eighth embodiment, the configurations of the photovoltaic conversion module 100 and the installation portion 200 are the same as those in the first embodiment. In the eighth embodiment, the area where the adhesive 300 is provided and the area of ​​the non-adhesive portion 380 are different from those in the first embodiment.

[0074] The adhesive 300 may be provided along the outer periphery of the photovoltaic conversion module 100. In the eighth embodiment, the non-adhesive portion 380 is provided at a position corresponding to at least one corner of the photovoltaic conversion module 100. Preferably, the non-adhesive portion 380 is provided at positions corresponding to all corners of the photovoltaic conversion module 100.

[0075] As a result, if there is a slight misalignment in the bonding positions of two adjacent sides of the photovoltaic conversion module 100 when the photovoltaic conversion module 100 is bonded, the effects of that misalignment tend to be concentrated at the corners of the photovoltaic conversion module 100. If the corners of the photovoltaic conversion module 100 are bonded in this state, wrinkles are likely to occur at the corners of the photovoltaic conversion module 100. On the other hand, if the corners of the photovoltaic conversion module 100 are not bonded, there is an advantage in that the effects of the misalignment in the bonding positions of the two adjacent sides of the photovoltaic conversion module 100 are relieved at the corners of the photovoltaic conversion module 100.

[0076] In the eighth embodiment, the non-adhesive portions 380 may be provided at positions other than the corners of the photovoltaic conversion module 100 (see FIG. 11). Alternatively, the non-adhesive portions 380 may be provided only at the corners of the photovoltaic conversion module 100.

[0077] Here, the installation method of the photovoltaic conversion module in the second to eighth embodiments can be carried out in the same manner as in the first embodiment, except that the pattern of the adhesive 300 and the non-adhesive portion 380 is changed from the pattern in the first embodiment to the pattern described in each embodiment.

[0078] As described above, the contents of the present invention have been disclosed through the embodiments, but the descriptions and drawings that form part of this disclosure should not be understood to limit the present invention. Various alternative embodiments, examples, and operating techniques will become apparent to those skilled in the art from this disclosure. Therefore, the technical scope of the present invention is defined only by the inventive features of the claims that can be reasonably understood from the above description.
