Description

[Technical field]

[0001] The present invention relates to an installation structure for a photovoltaic module. [Background technology]

[0002] As a conventional technique for the installation structure of a photovoltaic power generation module, a solar cell module fixing member is known that is provided with a main body fixed to the roof surface, a clamping part that clamps or fixes the end of the module, and a protrusion for electrical connection (see, for example, Patent Document 1). This structure makes it possible to fix and ground the module simply by inserting the end of the module, thereby enabling safe and reliable installation.

[0003] Another known prior art is a solar cell module arranged in an inclined direction that is composed of a solar cell panel and two types of frame material, with the upper frame material having a fitting portion and a protrusion, and the lower frame material having a fitting portion and a cover portion (see, for example, Patent Document 2). In this structure, the cover portion covers the protrusion portion of the lower module, forming a water passage. This structure prevents water from entering between adjacent solar cell modules, making it possible to reduce the installation area. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP2017-036578A [Patent Document 2] JP2010-251418A Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned conventional photovoltaic power generation module (hereinafter also referred to as "module") installation structure has several problems, as will be described below.

[0006] For example, a mounting frame may be required for installation. However, the presence of this mounting frame makes the module vulnerable to strong winds such as typhoons. In other words, in strong winds, a large force (wind pressure) can be applied to the entire module through the space left by the mounting frame, increasing the risk of damage or falling off.

[0007] In addition, the need to install anchors in the building created a risk of leaks. Specifically, holes had to be drilled in the roof and walls of the building to secure the anchors, which reduced the waterproofing performance. In the long term, there was concern that leaks could have a negative impact on the structure of the building.

[0008] Furthermore, there was also the problem that the rigidity of the module itself limited the surface on which it could be installed. Conventional modules were highly rigid and could only be installed on flat surfaces. This made it difficult to install on curved or irregularly shaped roofs or walls, limiting the range of application of solar power generation systems. Due to these factors, conventional installation structures lacked flexibility and were difficult to adapt to a variety of buildings and environments.

[0009] In other words, it can be said that there is room for improvement in the installation structures of the conventional techniques such as those of Patent Document 1 and Patent Document 2.

[0010] The present invention has been made in consideration of the above-mentioned circumstances, and its purpose is to provide an installation structure for a solar power generation module that realizes a solar power generation system that maintains high power generation efficiency while ensuring waterproofing of the building, and that can increase the freedom of installation and durability. [Means for solving the problem]

[0011] The above-mentioned object of the present invention is achieved by the following configuration. [1] a photovoltaic power generation module formed in a plate or sheet shape and fixed to an installation surface by joining its back surface to the installation surface; a sealing member disposed by filling a corner of a step between a peripheral portion of the solar power generation module and the installation surface; a resin layer stretched so as to surround the periphery of the solar power generation module; one end of the resin layer has a first region disposed on a tip end side thereof and a second region disposed on a base end side thereof, the first region is formed extending inward in a surface direction of the solar power generation module so as to overlap a peripheral portion of the solar power generation module in a thickness direction, and is laminated by bonding a back surface of the first region to a front surface of the peripheral portion of the solar power generation module; The second region is laminated by covering the sealing member in a thickness direction. Installation structure for solar power generation modules. [2] The solar power generation module is made of a flexible material that is curved in the thickness direction. [1] An installation structure for a solar power generation module according to the present invention. [3] The resin layer is a polyurea resin layer. [1] An installation structure for a solar power generation module according to the present invention. [4] The sealing member is sandwiched between the installation surface and the one end of the resin layer. [1] An installation structure for a solar power generation module according to the present invention. [5] The solar power generation module is directly fixed to the installation surface via an adhesive. [1] An installation structure for a solar power generation module according to the present invention.

[0012] It is advisable to use the configuration described above in [1]. In this case, the structure in which the plate-shaped or sheet-shaped photovoltaic module is fixed to the installation surface by bonding the back side thereof increases the adhesion to the installation surface, improving resistance to strong winds. This significantly reduces the risk of damage and falling off of the photovoltaic module. In addition, the structure in which the sealing material is filled and arranged in the step between the peripheral part of the photovoltaic module and the installation surface ensures waterproofing between the module and the installation surface. This can contribute to both protecting the building body and stable operation of the photovoltaic power generation system. Furthermore, the resin layer is stretched so as to surround the periphery of the panel of the photovoltaic power generation module, and one end of the resin layer has a first region and a second region, so that in the first region, a stable laminated structure is formed by bonding with the surface of the peripheral part of the module, and in the second region, the waterproof performance is enhanced by covering with the sealing material. In this way, high durability that can withstand long-term use in outdoor environments can be achieved, and cost and time can be reduced by simplifying the construction process. In addition, it is possible to adapt to installation surfaces of various shapes, greatly expanding the range of application of the photovoltaic power generation system. It is recommended to use the configuration described above in [2]. In this case, the flexibility of the flexible material allows installation on curved and irregular roofs and walls. This allows the solar power generation system to be installed on a variety of buildings that could not be accommodated with conventional rigid modules, significantly expanding the range of installations. In addition, the properties of the flexible material improve adhesion to the installation surface. This makes it less likely that gaps will form between the solar power generation module and the installation surface, reducing the risk of damage and falling off due to wind pressure during strong winds. Furthermore, since it is possible to fix it directly to the installation surface, the mounting and anchors that were previously required are no longer necessary. This simplifies the installation process, reduces costs and time, and eliminates the risk of rain leaks caused by the installation of anchors. It is recommended to use the configuration described above in [3]. In this case, by adopting a polyurea resin layer, its excellent waterproofing performance can achieve both protection of the building body and stable operation of the photovoltaic power generation system. Polyurea resin has high durability that can withstand long-term use in outdoor environments, which reduces the frequency of maintenance and extends the life of the system. In addition, the strength characteristics of the polyurea resin layer significantly improve resistance to strong winds such as typhoons, reducing the risk of damage and detachment of the photovoltaic power generation module. Furthermore, the polyurea resin layer can be directly fixed to the installation surface, which simplifies the construction process and reduces costs and time. In addition, it can be adapted to installation surfaces of various shapes, and can be installed not only on flat surfaces but also on buildings with curved surfaces and irregular shapes. It is recommended to use the configuration described above in [4]. In this case, the structure in which the sealing member is sandwiched between the installation surface and one end of the resin layer improves the fixation of the sealing member, and more reliable waterproof performance can be achieved. Such a sandwiching structure can effectively suppress the deterioration of the sealing member over time and deformation due to environmental loads, and ensure long-term reliability. In addition, by reliably fixing both sides (front and back) of the sealing member, stress due to temperature changes and vibrations caused by typhoons, for example, can be dispersed, and the risk of peeling and damage of the sealing member can be reduced. Furthermore, this structure makes it easier to position the sealing member during construction, and can achieve stabilization of construction quality and improvement of work efficiency. It is recommended to use the configuration described above in [5]. In this case, the structure in which the photovoltaic power generation module is directly fixed to the installation surface via an adhesive material can increase the adhesion between the photovoltaic power generation module and the installation surface, improving resistance to strong winds. This reduces the risk of damage and detachment of the photovoltaic power generation module, and improves the reliability of the entire photovoltaic power generation system. Effect of the Invention

[0023] First Embodiment The installation structure of a photovoltaic power generation module 1 according to the present invention will be described with reference to Figs.

[0024] [Basic structure] An example of the structure of a photovoltaic power generation module 1 according to this embodiment will be described with reference to FIG. FIG. 1 is a schematic diagram illustrating a photovoltaic power generation module 1 used in the installation structure of the present embodiment.

[0025] As shown in FIG. 1, the installation structure of this embodiment is configured to include a photovoltaic power generation module 1 formed to extend in a plate or sheet shape, for example, to be set on the roof of a building.

[0026] This photovoltaic power generation module 1 is fixedly mounted by bonding its back surface to a predetermined mounting surface SS. This mounting surface SS is a surface that receives appropriate sunlight, and the photovoltaic power generation module 1 is made of a flexible material 1A that can be bent in the thickness direction. Unlike conventional photovoltaic power generation modules 1 that have rigidity, this flexible material 1A can be deformed to follow the shape of the mounting surface SS.

[0027] Specifically, the photovoltaic power generation module 1 of this embodiment is provided by sealing a high-performance power generation element (not shown) that realizes a predetermined conversion efficiency in a flexible resin material. The thickness of this module is formed into a film-like shape that is thinner than conventional products, and the weight is also reduced.

[0028] With such a configuration, the photovoltaic power generation module 1 of this embodiment can be installed not only on a flat installation surface SS, but also on an installation surface SS having a curved or irregular shape, while curving to fit the shape of the surface.

[0029] For example, even if the installation surface SS (in one example of this embodiment, a curved roof) has a curvature as shown in FIG. 1, the solar power generation module 1 can be curved so as to be in close contact with the installation surface SS, thereby preventing a gap from occurring between the solar power generation module 1 and the installation surface SS.

[0030] In addition, the photovoltaic power generation module 1 of this embodiment has a structure that has high adhesion to the installation surface SS due to its flexibility, and wind is unlikely to get in between the module and the installation surface SS even during strong winds. This improves resistance to strong winds such as typhoons, and can reduce the risk of damage or detachment of the module.

[0031] Furthermore, because it is made of flexible material 1A, it can be installed on building walls and curved roof surfaces, where installation was difficult with conventional rigid modules, making it possible to significantly expand the range of application of solar power generation systems.

[0032] [·Installation structure] An example of an installation structure for the photovoltaic power generation module 1 according to this embodiment will be described with reference to Figs. 2 and 3. FIG. 2 is a schematic cross-sectional view illustrating a cross-section of the installation structure of the present embodiment. FIG. 3 is a plan view illustrating a state in which the installation structure of this embodiment is used.

[0033] As shown in Figs. 2 and 3, the installation structure of this embodiment is a structure for fixing the above-mentioned photovoltaic power generation module 1 to an installation surface SS, such as a ceiling surface or a wall surface.

[0034] Specifically, the photovoltaic power generation module 1 is arranged with its back surface facing the installation surface SS and fixed to a predetermined installation surface SS via an adhesive (not shown). This adhesive ensures the bonding strength between the photovoltaic power generation module 1 and the installation surface SS and also provides a waterproof function.

[0035] The adhesive in this embodiment is applied uniformly over the entire back surface of the photovoltaic power generation module 1 to prevent the occurrence of a gap between the photovoltaic power generation module 1 and the installation surface SS. In addition, this adhesive is made of a material having elasticity capable of following the thermal expansion and contraction of the photovoltaic power generation module 1. This makes it possible to absorb stress due to temperature changes and prevent the photovoltaic power generation module 1 from deforming and peeling off.

[0036] This adhesion forms a step ST between the installation surface SS and the photovoltaic power generation module 1 over the entire periphery of the photovoltaic power generation module 1. That is, a step ST is provided between the periphery of the photovoltaic power generation module 1 and the installation surface SS. In this embodiment, a sealing member 2 is filled and disposed in the corners of the step ST between the periphery of the photovoltaic power generation module 1 and the installation surface SS. This sealing member 2 has the function of ensuring waterproofing between the photovoltaic power generation module 1 and the installation surface SS.

[0037] Furthermore, a polyurea resin layer 3 (an example of a "resin layer") is laid so as to surround the periphery of the panel of the photovoltaic power generation module 1. This polyurea resin layer 3 is applied by a spraying method. The polyurea resin layer 3 is formed, for example, by mixing two liquids, an isocyanate component and an amine component, under high pressure and high temperature, and spraying them directly onto the installation surface SS using a dedicated spray gun (not shown). In this spraying method, a rapid polymerization reaction progresses immediately after the two liquids come into contact, and hardening begins within a few seconds, making it possible to apply the layer quickly and with a uniform thickness. In addition, it is easy to apply the layer to vertical and curved surfaces. During application, the installation surface SS is properly cleaned and primed, and a primer treatment is applied as necessary to ensure adhesion between the polyurea resin layer 3 and the installation surface SS.

[0038] Through these steps, the polyurethane resin layer 3 is formed into a sheet or layer, and is attached in a state in which its back surface is bonded and fixed to the installation surface SS. As described above, the polyurethane resin layer 3 of this embodiment is stretched so as to surround the periphery of the photovoltaic power generation module 1. One end portion of the layer 3 is formed to extend so as to overlap in the thickness direction with the peripheral portion of the photovoltaic power generation module 1 in a portion thereof ("first region A1" described later) (see FIG. 2).

[0039] That is, as shown in FIG. 2, this one end portion is configured to have a first region A1 disposed on the tip end side thereof and a second region A2 disposed on the base end side thereof.

[0040] The first region A1 is a portion that is formed extending inward in the surface direction of the solar power generation module 1 so as to overlap the peripheral portion of the solar power generation module 1 in the thickness direction, and is laminated by joining the back surface of the first region A1 to the surface of the peripheral portion of the solar power generation module 1.

[0041] In other words, in the installation structure of this embodiment, the polyurethane resin layer 3 is formed with rectangular openings in the portions corresponding to the respective photovoltaic power generation modules 1 so that the surface of the photovoltaic power generation modules 1 can receive light. The opening edges extend away from the periphery of the photovoltaic power generation module 1 inward in the planar direction. This extending portion overlaps with the surface of the periphery of the photovoltaic power generation module 1 in the thickness direction, and this overlapping portion is defined as the first region A1.

[0042] On the other hand, in the second region A2, one end of the polyurethane resin layer 3 is laminated covering the sealing member 2 in the thickness direction. By laminating, the sealing member 2 is sandwiched and fixed between the installation surface SS and one end of the polyurethane resin layer 3 (second region A2). In other words, the lower surface of the sealing member 2 is in close contact with the installation surface SS, and the upper surface of the sealing member 2 is covered by one end of the polyurethane resin layer 3, so that the sealing member 2 is sandwiched between the installation surface SS and one end of the resin layer. In this way, by sandwiching the sealing member 2 between the installation surface SS and one end of the polyurethane resin layer 3, it becomes possible to stably hold the sealing member 2 at a predetermined position.

[0043] The polyurethane resin layer 3 is disposed above the sealing member 2, thereby forming a structure that protects the sealing member 2. That is, one end of the polyurethane resin layer 3 extends so as to cover the upper part of the sealing member 2, thereby preventing direct contact between the sealing member 2 and the external environment. With such a structure, the sealing member 2 is physically protected by the polyurethane resin layer 3, and is protected from deterioration due to ultraviolet rays and wind and rain from the outside.

[0044] [About the polyurea resin layer] An example of the polyurea resin layer 3 (an example of a "resin layer") will be described.

[0045] The polyurea resin used in this embodiment is a synthetic resin that functions as a high-performance waterproof material.

[0046] By adopting the polyurethane resin layer 3 of this embodiment, it is possible to achieve both protection of the building body and stable operation of the solar power generation system due to its excellent waterproof performance. In addition, the polyurethane resin layer 3 has high durability that can withstand long-term use in outdoor environments, thereby reducing the frequency of maintenance and extending the life of the system.

[0047] Furthermore, the polyurethane resin layer 3 of this embodiment has an effect of significantly improving resistance to strong winds such as typhoons, and reducing the risk of damage and falling off of the photovoltaic power generation module 1. This is a characteristic effect achieved by the polyurethane resin layer 3 integrating the module and the installation surface SS.

[0048] As mentioned above, the polyurethane resin layer 3 can be fixed directly to the installation surface SS, which simplifies the construction process and reduces costs and time. In addition, it can be adapted to installation surfaces SS of various shapes, and can be installed not only on flat surfaces but also on buildings with curved or irregular shapes.

[0049] As described above, the polyurethane resin layer 3 of the present embodiment plays an important role in the installation structure of a photovoltaic power generation system, and has a technical feature of improving the performance and reliability of the entire system.

[0050] [Features and advantages of this embodiment] [1] As described above, the installation structure of the photovoltaic power generation module 1 of this embodiment includes the photovoltaic power generation module 1 formed in an elongated plate or sheet shape and fixedly installed by bonding its back surface to the installation surface SS, the sealing member 2 filled and arranged at the corner of the step ST between the peripheral portion of the photovoltaic power generation module 1 and the installation surface SS, and the polyurea resin layer 3 (an example of a "resin layer") stretched so as to surround the periphery of the photovoltaic power generation module 1. One end of the polyurea resin layer 3 has a first region A1 arranged on its tip side and a second region A2 arranged on its base end side. The first region A1 is formed by extending inward in the surface direction of the photovoltaic power generation module 1 so as to overlap the peripheral portion of the photovoltaic power generation module 1 in the thickness direction, and is bonded and laminated on the surface of the peripheral portion of the photovoltaic power generation module 1 with its back surface. The second region A2 is laminated by covering the sealing member 2 in the thickness direction.

[0051] Therefore, the structure in which the plate-shaped or sheet-shaped photovoltaic module 1 is fixed to the installation surface SS by bonding the back side thereof, improves adhesion to the installation surface SS, and improves resistance to strong winds. This significantly reduces the risk of damage and falling off of the photovoltaic module 1. In addition, the structure in which the sealing material 2 is filled and arranged in the step ST between the peripheral portion of the photovoltaic module 1 and the installation surface SS ensures waterproofing between the module and the installation surface SS. This can contribute to both protecting the building body and stable operation of the photovoltaic power generation system. Furthermore, the polyurea resin layer 3 (an example of a "resin layer") is stretched so as to surround the periphery of the panel of the photovoltaic module 1, and one end of the layer has a first area A1 and a second area A2, so that in the first area A1, a stable laminated structure is formed by bonding with the surface of the peripheral portion of the module, and in the second area A2, the waterproof performance is enhanced by covering with the sealing material 2. In this way, high durability that can withstand long-term use in outdoor environments can be achieved, and cost and time can be reduced by simplifying the construction process. In addition, it will be possible to adapt to installation surfaces SS of various shapes, greatly expanding the range of application of solar power generation systems.

[0052] [2] Moreover, according to the installation structure of the photovoltaic power generation module 1 of this embodiment, the photovoltaic power generation module 1 is made of a flexible material 1A that curves in the thickness direction.

[0053] Therefore, the flexibility of the flexible material 1A allows installation on curved and irregular roofs and walls. This allows the solar power generation system to be applied to a variety of buildings that could not be handled by conventional modules with high rigidity, significantly expanding the range of installation. In addition, the properties of the flexible material 1A improve adhesion to the installation surface SS. This makes it difficult for gaps to form between the solar power generation module 1 and the installation surface SS, reducing the risk of damage and falling off due to wind pressure during strong winds. Furthermore, since it is possible to fix the solar power generation module directly to the installation surface SS, the mounting base and anchors that were previously required are no longer necessary. This simplifies the installation process, reduces costs and time, and eliminates the risk of rain leakage caused by the installation of anchors.

[0054] [3] Moreover, according to the installation structure of the photovoltaic power generation module 1 of this embodiment, the resin layer is a polyurethane resin layer 3.

[0055] Therefore, by adopting the polyurea resin layer 3, its excellent waterproofing performance makes it possible to protect the building body and ensure stable operation of the photovoltaic power generation system. Polyurea resin has high durability that can withstand long-term use in outdoor environments, which reduces the frequency of maintenance and extends the life of the system. In addition, the strength characteristics of the polyurea resin layer 3 significantly improve resistance to strong winds such as typhoons, reducing the risk of damage and detachment of the photovoltaic power generation module 1. Furthermore, the polyurea resin layer 3 can be directly fixed to the installation surface SS, which simplifies the construction process and reduces costs and time. In addition, it can be adapted to installation surfaces SS of various shapes, and can be installed not only on flat surfaces but also on buildings with curved surfaces and irregular shapes.

[0056] [4] Moreover, according to the installation structure of the photovoltaic power generation module 1 of this embodiment, the sealing member 2 is sandwiched between the installation surface SS and one end of the polyurethane resin layer 3 (an example of a "resin layer").

[0057] Therefore, the structure in which the sealing member 2 is sandwiched between the installation surface SS and one end of the polyurethane resin layer 3 (an example of a "resin layer") improves the fixation of the sealing member 2, and more reliable waterproof performance can be achieved. Such a sandwiching structure effectively suppresses the deformation of the sealing member 2 due to deterioration over time and environmental loads, and ensures long-term reliability. In addition, by securely fixing both sides (front and back) of the sealing member 2, stress due to temperature changes and vibrations caused by, for example, typhoons can be dispersed, and the risk of peeling and damage of the sealing member 2 can be reduced. Furthermore, this structure makes it easier to position the sealing member 2 during construction, and it is possible to stabilize construction quality and improve work efficiency.

[0058] [5] Moreover, according to the installation structure of the photovoltaic power generation module 1 of this embodiment, the photovoltaic power generation module 1 is directly fixed to the installation surface SS via an adhesive material.

[0059] Therefore, by directly fixing the photovoltaic power generation module 1 to the installation surface SS via an adhesive, the adhesion between the photovoltaic power generation module 1 and the installation surface SS can be increased, improving resistance to strong winds. This reduces the risk of damage and falling off of the photovoltaic power generation module 1, improving the reliability of the entire photovoltaic power generation system.
