DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0013] There is a growing need to install solar panels in order to expand the use of renewable energy and promote energy conservation. For example, when installing solar panels in urban areas with many high-rise buildings, the buildings can block sunlight, resulting in poor power generation efficiency near the ground. On the other hand, the rooftops of high-rise buildings, which have good sunlight exposure, are equipped with various devices such as air conditioning and power generation equipment, and if solar panels are to be installed using conventional installation methods, there is almost no space available under ideal conditions. It is desirable to be able to install solar panels easily and inexpensively in places where installation was previously difficult. Furthermore, solar power generation systems must be able to withstand such installation environments with the necessary durability.

[0014] The holding device 20 according to this embodiment has a configuration that contributes to solving these problems. For example, the holding device 20 can hold a solar panel to a curtain-like member relatively easily. For example, by using a solar power generation system that includes the holding device 20 and a thin, small, lightweight, and inexpensive solar panel that has recently become available on the market, the solar panel can be installed anywhere the curtain-like member can be installed.

[0015] FIG. 1 schematically illustrates an example of a solar power generation system 10. The solar power generation system 10 includes a holding fixture 20 and a solar panel 100. The holding fixture 20 includes a panel mounting fixture 200. The holding fixture 20 may include a panel mounting curtain 300. The holding fixture 20 does not have to include the panel mounting curtain 300. In this case, the holding fixture 20 may hold the solar panel 100 to an existing panel mounting curtain.

[0016] In the example shown in FIG. 1 , the type and structure of the solar panel 100 are not particularly limited. The type of solar panel 100 may be silicon-based, compound-based, organic-based, or the like. If the solar panel 100 is silicon-based, the solar panel 100 may be a crystalline silicon solar cell, an amorphous silicon solar cell, or the like. If the solar panel 100 is compound-based, the solar panel 100 may be a III-V multijunction solar cell, a copper-indium-selenium solar cell, a cadmium-tellurium solar cell, or the like. If the solar panel 100 is organic-based, the solar panel 100 may be a dye-sensitized solar cell, a perovskite solar cell, an organic semiconductor solar cell, or the like. For example, the solar panel 100 may have a flexible structure. The solar panel 100 may also have a rigid structure. In the example shown in FIG. 1 , the shape of the solar panel 100 is rectangular, but is not particularly limited. The shape of the solar panel 100 may be, for example, a polygon with pentagons or more, a triangle, a circle, or an ellipse. 1 and subsequent figures will be described using an example in which the solar panel 100 is rectangular.

[0017] The solar panel 100 has a power generating element section 110, which is a section where power generating elements are arranged. The solar panel 100 also has a non-power generating element section 120, which is a section where power generating elements are not arranged. The non-power generating element section 120 of the solar panel 100 is, for example, a back surface 126 or an edge section 122 of the solar panel 100. The edge section 122 may include a corner section 124.

[0018] The panel mounting fixture 200 holds the solar panel 100 to the panel mounting curtain 300. The panel mounting fixture 200 holding the solar panel 100 to the panel mounting curtain 300 may mean that the panel mounting fixture 200 maintains the state in which the solar panel 100 is installed on the panel mounting curtain 300. The panel mounting fixture 200 holding the solar panel 100 to the panel mounting curtain 300 may include the panel mounting fixture 200 fixing the solar panel 100 to the panel mounting curtain 300. The panel mounting fixture 200 holding the solar panel 100 to the panel mounting curtain 300 may include the panel mounting fixture 200 not fixing the solar panel 100 to the panel mounting curtain 300, but installing the solar panel 100 so that it is movable relative to the panel mounting curtain 300.

[0019] The panel mounting fixture 200 holds the solar panel 100 to the panel mounting curtain 300 so as not to block the reception of sunlight 92 by the power generating element section 110. The panel mounting fixture 200 may partially block the reception of sunlight 92 by the power generating element section 110. The panel mounting fixture 200 may hold the solar panel 100 by holding the non-power generating element section 120 to the panel mounting curtain 300. The panel mounting fixture 200 may hold the solar panel 100 by holding the edge section 122 of the solar panel 100 to the panel mounting curtain 300. In the example shown in FIG. 1 , the panel mounting fixture 200 holds two opposing edge sections 122 of the multiple edge sections 122 of the solar panel 100, but the method of holding the edge sections 122 is not limited to this. For example, the panel mounting fixture 200 may hold all of the edge sections 122, or may hold two non-opposing edge sections 122.

[0020] In the example shown in FIG. 1 , the panel mounting fixture 200 holds the non-power-generating element portion 120 on the front surface on which the power-generating element portion 110 is disposed. However, the panel mounting fixture 200 may also hold the non-power-generating element portion 120 on the back surface. For example, the panel mounting fixture 200 may be fixed to the back surface of the solar panel 100, and the panel mounting fixture 200 may be fixed to the panel mounting curtain 300 by the fixing portion 210, thereby holding the solar panel 100 to the panel mounting curtain 300. In this case, the panel mounting fixture 200 may be disposed between the panel mounting curtain 300 and the solar panel 100. This reduces the exposure of the panel mounting fixture 200 to direct sunlight, thereby reducing deterioration of the panel mounting fixture 200 due to ultraviolet rays. This in turn improves the durability of the holding fixture 20. This also makes it possible to install solar panels 100 in which the surface of the solar panel 100 does not have a non-power-generating element portion 120 with an area sufficient to hold the solar panel 100.

[0021] The power generating element section 110 of the solar panel 100 may be divided into multiple sections by the non-power generating element sections 120. In the example shown in Fig. 1 , the power generating element section 110 is divided into 10 sections. The panel mounting fixture 200 may hold the solar panel 100 by holding the non-power generating element sections 120 that divide the power generating element section 110 to the panel mounting screen 300.

[0022] 1 , the retaining device 20 includes a fixing portion 210. The panel mounting fixture 200 may be fixed to the panel mounting curtain 300 by the fixing portion 210. The panel mounting fixture 200 may include the fixing portion 210. The method by which the fixing portion 210 fixes the panel mounting fixture 200 to the panel mounting curtain 300 is not particularly limited. For example, the fixing portion 210 may fix the panel mounting fixture 200 to the panel mounting curtain 300 by a method such as gluing, sewing, or stapling.

[0023] The fixing portion 210 does not have to completely fix the panel mounting fixture 200 to the panel mounting curtain 300. The fixing portion 210 may merely hold the panel mounting fixture 200 to the panel mounting curtain 300. For example, the fixing portion 210 may be magnetic. In this case, the fixing portion 210 may include two magnet portions that sandwich the panel mounting curtain 300 from both sides of the panel mounting curtain 300 and attract each other to fix the panel mounting fixture 200 to the panel mounting curtain 300. This makes it possible to easily attach and detach the panel mounting fixture 200 to the panel mounting curtain 300. The holding device 20 does not have to include the fixing portion 210.

[0024] In the example shown in FIG. 1 , the panel mounting curtain 300 includes a curtain portion 310 and a fixing portion 320. The material and structure of the curtain portion 310 are not particularly limited. The curtain portion 310 may be made of, for example, plastic. The curtain portion 310 may be made of, for example, polyethylene. The curtain portion 310 may have, for example, a mesh structure. The curtain portion 310 may have, for example, a mesh structure. Only a portion of the curtain portion 310, rather than the entire curtain portion 310, may have these structures. For example, the curtain portion 310 may include a mesh-like mesh portion. This allows wind to pass through the curtain portion 310 more easily, for example, in windy environmental conditions, thereby reducing the wind pressure experienced by the solar power generation system 10. Furthermore, when it rains, rainwater can easily pass through the curtain portion 310, thereby preventing rainwater from accumulating on the curtain portion 310. The panel mounting curtain 300 may be fixed to any installation location by the fixing portion 320. This allows the solar power generation system 10 to be installed in locations where it has been difficult to install solar panels using conventional installation methods, such as spaces on the roof of a building between handrails and various pieces of equipment, or spaces between various pieces of equipment and the building's frame. The panel mounting curtain 300 may be a sunshade that blocks sunlight.

[0025] Fig. 2 schematically illustrates an example of a solar power generation system 10. In Fig. 2, differences from the example illustrated in Fig. 1 will be mainly described, and descriptions of commonalities with the example illustrated in Fig. 1 will be omitted.

[0026] In the example shown in FIG. 2, the holding device 20 does not have a fixing portion 210. In the example shown in FIG. 2, the panel mounting device 200 is ring-shaped. In the example shown in FIG. 2, the panel mounting device 200 may have a seamless structure. In this case, the panel mounting curtain 300 may be passed through the space inside the ring shape of the panel mounting device 200, so that the panel mounting device 200 holds the solar panel 100 to the panel mounting curtain 300. In this case, the solar panel 100 may be held movably relative to the panel mounting curtain 300. In this case, the solar panel 100 may be held slidably relative to the panel mounting curtain 300. This not only makes it easy to install the solar panel 100, but also makes it possible to withstand forces applied to the panel mounting curtain 300 and the solar panel 100 due to strong winds, etc., thereby preventing damage to the holding device 20. In addition, the solar panel 100 can be held regardless of the dimensions of the solar panel 100.

[0027] In the example shown in FIG. 2 , when the solar panel 100 is held movably relative to the panel mounting curtain 300, friction occurs between the panel mounting bracket 200 and the panel mounting curtain 300. As a result, wear and tear on the panel mounting bracket 200 and the panel mounting curtain 300 due to friction can become a problem. For example, the materials of the panel mounting bracket 200 and the panel mounting curtain 300 may be selected with consideration given to high wear resistance. For example, the materials of the panel mounting bracket 200 and the panel mounting curtain 300 may be selected with consideration given to low wear energy. The materials of the panel mounting bracket 200 and the panel mounting curtain 300 may be selected with consideration given to the coefficient of friction. For example, by reducing the coefficient of friction between the material of the panel mounting bracket 200 and the material of the panel mounting curtain 300, the frictional force is reduced, and therefore the wear energy applied to the panel mounting bracket 200 and the panel mounting curtain 300 can be reduced. For example, by increasing the coefficient of friction between the material of the panel mounting fixture 200 and the material of the panel mounting curtain 300, the frictional force increases and the sliding distance between the panel mounting fixture 200 and the panel mounting curtain 300 can be reduced, thereby reducing the wear energy applied to the panel mounting fixture 200 and the panel mounting curtain 300. This improves the wear resistance of the panel mounting fixture 200 and the panel mounting curtain 300, and ultimately improves the durability of the solar power generation system 10. The panel mounting fixture 200 may have a wear reduction portion that reduces wear between the panel mounting curtain 300 and the solar panel 100. The material of the wear reduction portion may be selected using the same method as for selecting the material of the panel mounting fixture 200 described above.

[0028] FIG. 3 schematically illustrates an example of a solar power generation system 10. In FIG. 3, differences from the example illustrated in FIG. 1 will be mainly described, and descriptions of commonalities with the example illustrated in FIG. 1 will be omitted. In the example illustrated in FIG. 3, the panel mounting fixture 200 has a belt portion 220. The belt portion 220 holds the edge portion 122 to the panel mounting curtain 300. In the example illustrated in FIG. 3, the belt portion 220 may be fixed to the panel mounting curtain 300 by a fixing portion 210. The belt portion 220 may also include the fixing portion 210. In the example illustrated in FIG. 3, the panel mounting fixture 200 has four belt portions 220, but the number of belt portions 220 does not have to be four, and may be two, three, five or more.

[0029] The belt portion 220 may include a buckle portion 222. The buckle portion 222 may have a structure that allows the length of the belt portion 220 to be adjusted and the belt portion 220 to be attached and detached. This allows the solar panel 100 to be easily installed. Furthermore, the solar panel 100 can be held regardless of the dimensions of the solar panel 100.

[0030] In the example shown in FIG. 3 , the panel mounting curtain 300 has an opening 330 through which the belt portion 220 passes. The opening 330 may be reinforced by an opening reinforcement portion 332. The method of reinforcement using the opening reinforcement portion 332 is not particularly limited. For example, the opening reinforcement portion 332 may be reinforced by sewing the edge of the opening 330 or by using metal parts or the like. For example, the opening reinforcement portion 332 has an eyelet structure. This allows, for example, when a solar panel 100 is to be held to an existing panel mounting curtain 300 using the holding device 20, the opening 330 having the opening reinforcement portion 332 can be relatively easily formed at a desired position on the panel mounting curtain 300 using a tool for processing eyelets, such as an eyelet punch.

[0031] FIG. 4 schematically illustrates an example of a solar power generation system 10. In FIG. 4, differences from the example illustrated in FIG. 3 will be mainly described, and descriptions of commonalities with the example illustrated in FIG. 3 will be omitted. In the example illustrated in FIG. 4, the holder 20 does not have a fixing portion 210. In the example illustrated in FIG. 4, the belt portion 220 is ring-shaped. In this case, work such as gluing or sewing to fix the belt portion 220 to the panel mounting screen 300 is not required, and therefore the solar panel 100 can be installed more easily.

[0032] Fig. 5 schematically illustrates an example of a solar power generation system 10. In Fig. 5, differences from the example illustrated in Fig. 1 will be mainly described, and descriptions of commonalities with the example illustrated in Fig. 1 will be omitted.

[0033] 5 , the panel mounting curtain 300 has an opening 330. The panel mounting fixture 200 clamps the edge 122 of the solar panel 100 and has a frame portion 230 including ears 232, and a band portion 238. The band portion 238 passes through ear openings 234 provided in the ears 232 and the opening 330, and holds the ears 232 to the panel mounting curtain 300.

[0034] In the example shown in Fig. 5, the shape of the frame portion 230 is rectangular, but is not limited to this. In the example shown in Fig. 5, the shape and size of the frame portion 230 may be selected according to the shape of the solar panel 100, within a range in which the solar panel 100 can be stably held. In the example shown in Fig. 5, the frame portion 230 has a structure that sandwiches the edge portion 122 so as to surround the entire periphery of the solar panel 100. The frame portion 230 may also have a structure that sandwiches a portion of the edge portion 122 of the entire periphery of the solar panel 100. The frame portion 230 may be made of any material. For example, the frame portion 230 is made of metal, plastic, etc.

[0035] In the example shown in FIG. 5 , the frame portion 230 has one strip-shaped ear 232 on each of two opposing sides of the frame portion 230, but this is not limiting. The frame portion 230 may have the ear 232 at any part of the entire periphery of the frame portion 230. The frame portion 230 may have the ear 232 on the back surface of the frame portion 230. The frame portion 230 may have the ear 232 at multiple parts of the frame portion 230. The frame portion 230 may have the ear 232 at the corners of the frame portion 230. The shape of the ear 232 may be any shape. The material of the ear 232 may be any material. For example, the material of the ear 232 is metal, plastic, etc.

[0036] The frame portion 230 and the ear portions 232 may be made of the same material or different materials. In the example shown in Fig. 5, the frame portion 230 and the ear portions 232 are formed separately and the ear portions 232 are fixed to the frame portion 230, but the frame portion 230 and the ear portions 232 may also be formed integrally. For example, the frame portion 230 and the ear portions 232 may be formed integrally, and the frame portion 230 may have ear openings 234.

[0037] The ear opening 234 may be reinforced by an ear opening reinforcing portion 236. The method of reinforcement by the ear opening reinforcing portion 236 is not particularly limited. For example, the ear opening reinforcing portion 236 may be reinforced by sewing the edge of the ear opening 234, or by using metal parts or the like. For example, the ear opening reinforcing portion 236 has an eyelet structure. In the example shown in FIG. 5, the opening 330 of the panel mounting screen 300 may be reinforced by an opening reinforcing portion 332, similar to the example shown in FIG. 3.

[0038] In the example shown in FIG. 5 , the band portion 238 has a ring-shaped structure. In this case, the band portion 238 may include an opening / closing portion that allows the ring-shaped structure of the band portion 238 to be opened and closed. This improves the ease of installation of the panel mounting device 200 on the panel mounting screen 300. The band portion 238 does not have to have a ring-shaped structure. For example, the band portion 238 may be dumbbell-shaped, including a linear portion and retaining portions located at both ends of the linear portion. In this case, the shape and size of the retaining portions may be any shape and size as long as they can prevent the band portion 238 from slipping out of the ear openings 234 and the openings 330. For example, the linear portion may be a bolt, and the retaining portion may be a nut. The band portion 238 may be made of any material. For example, the band portion 238 may be made of metal, plastic, or the like. The band portion 238 may be made of an elastic material. As a result, when a force is applied to the solar panel 100 due to a strong wind or the like, the elastic body stretches and is able to absorb the force, thereby preventing the holder 20 from being damaged.

[0039] Fig. 6 shows a schematic diagram of an example of a solar power generation system 10. In Fig. 6, differences from the example shown in Fig. 5 will be mainly described. In the example shown in Fig. 6, the ears 232 have a structure in which they partially protrude from the outer periphery of the frame part 230. The ears 232 may be substantially circular. The ears 232 may be ring-shaped.

[0040] Fig. 7 schematically illustrates an example of a solar power generation system 10. In Fig. 7, differences from the example illustrated in Fig. 1 will be mainly described, and a description of commonalities with the example illustrated in Fig. 1 will be omitted.

[0041] In the example shown in FIG. 7 , the panel mounting fixture 200 has a pocket portion 240 that holds the edge portion 122 of the solar panel 100 on the panel mounting curtain 300. In the example shown in FIG. 7 , the shape of the pocket portion 240 is rectangular, but is not limited thereto. In the example shown in FIG. 7 , the shape and size of the pocket portion 240 may be selected according to the shape of the solar panel 100 as long as the solar panel 100 can be stably held. For example, the pocket portion 240 may hold the solar panel 100 so that the solar panel 100 can move within the pocket portion 240. In the example shown in FIG. 7 , the opening direction of the pocket of the pocket portion 240 is the direction in which the fixing portion 320 of the panel mounting curtain 300 is located, but the opening direction of the pocket of the pocket portion 240 is not limited thereto. For example, the opening direction of the pocket of the pocket portion 240 may be perpendicular to the direction in which the fixing portion 320 of the panel mounting curtain 300 is located, or may be at another angle.

[0042] Fig. 8 schematically illustrates an example of a solar power generation system 10. In Fig. 8, differences from the example illustrated in Fig. 7 will be mainly described, and descriptions of commonalities with the example illustrated in Fig. 7 will be omitted.

[0043] 8, the panel mounting fixture 200 has a plurality of pockets 240 configured to hold a plurality of corners 124 of the edge 122 of the solar panel 100. In the example shown in Fig. 8, the plurality of pockets 240 hold all of the corners 124 of the solar panel 100, but this is not limited to this. For example, the plurality of pockets 240 may be configured to hold at least two of the plurality of corners 124 of the solar panel 100.

[0044] 8, the shape of each of the multiple pockets 240 is triangular, but is not limited to this. As with the example shown in Fig. 7, the shape and size of the pockets 240 may be selected according to the shape of the solar panel 100 within a range that allows the solar panel 100 to be stably held. For example, the shape of the pockets 240 may be determined according to the angle of the corners 124.

[0045] Fig. 9 schematically illustrates an example of a solar power generation system 10. In Fig. 9, differences from the example illustrated in Fig. 1 will be mainly described, and a description of commonalities with the example illustrated in Fig. 1 will be omitted.

[0046] 9, the panel mounting fixture 200 has a rail portion 250. The panel mounting fixture 200 holds the solar panel 100 to the panel mounting curtain 300 by holding multiple edge portions 122 of the solar panel 100 to the rail portion 250. The panel mounting fixture 200 may hold the solar panel 100 to the panel mounting curtain 300 so that the solar panel 100 can slide on the rail.

[0047] In the example shown in FIG. 9 , the rail portion 250 of the panel mounting fixture 200 is arranged in the direction connecting the two fixing portions 320 of the panel mounting curtain 300, and the solar panel 100 is held slidably on the rail in that direction, but this is not limited to this. For example, the rail portion 250 of the panel mounting fixture 200 may be arranged in a direction perpendicular to the direction connecting the two fixing portions 320 of the panel mounting curtain 300. For example, the solar panel 100 may be held slidably on the rail in a direction perpendicular to the direction connecting the two fixing portions 320 of the panel mounting curtain 300. This not only simplifies installation of the solar panel 100 but also counteracts forces acting on the panel mounting curtain 300 and the solar panel 100 due to strong winds and the like, thereby preventing damage to the holding device 20. Furthermore, the solar panel 100 can be held regardless of the dimensions of the solar panel 100.

[0048] Fig. 10 schematically illustrates an example of a solar power generation system 10. In Fig. 10, differences from the example illustrated in Fig. 1 will be mainly described, and descriptions of commonalities with the example illustrated in Fig. 1 will be omitted.

[0049] 10 , the panel mounting fixture 200 has a sunlight-transmitting portion 242 that transmits sunlight 92, and includes a pocket portion 240 that can store the solar panel 100 so that the power generation element portion 110 of the solar panel 100 is located in the sunlight-transmitting portion 242. For example, when the solar power generation system 10 is installed so that the side of the solar panel 100 with the power generation element portion 110 facing upward, the solar panel 100 may be stored in the pocket portion 240 so that the power generation element portion 110 is located below the sunlight-transmitting portion 242. For example, when the solar power generation system 10 is installed so that the side of the solar panel 100 with the power generation element portion 110 facing to the side, the solar panel 100 may be stored in the pocket portion 240 so that the power generation element portion 110 is located to the side of the sunlight-transmitting portion 242. The entire pocket portion 240 may be configured to transmit sunlight 92.

[0050] The pocket 240 may have a pocket opening / closing part 246. The pocket opening / closing part 246 may be sized to allow the solar panel 100 to be put in and taken out of the pocket 240. The pocket 240 may have a waterproof structure to the extent that liquid such as water droplets does not enter the pocket 240, and the pocket opening / closing part 246 may have a waterproof structure to the extent that the waterproof structure of the pocket 240 is realized. The pocket 240 does not have to have the pocket opening / closing part 246.

[0051] The pocket portion 240 may have a cable hole 244 that allows the wiring cable 130 of the solar panel 100 to be routed outside the pocket portion 240. The pocket portion 240 may be capable of storing the solar panel 100 such that the solar panel 100 is movable within the pocket portion 240. The pocket portion 240 does not have to have the cable hole 244.

[0052] Fig. 11 schematically illustrates an example of a solar power generation system 10. In Fig. 11, differences from the example illustrated in Fig. 10 will be mainly described, and a description of commonalities with the example illustrated in Fig. 10 will be omitted.

[0053] 11, the panel mounting curtain 300 holds multiple solar panels 100, and has a separation portion 202 between each of the multiple solar panels 100. This improves the wind and rain permeability of the solar power generation system 10 compared to a case where the separation portion 202 is not present, and reduces the effects of wind and rain. This increases the degree of freedom in where the solar power generation system 10 can be installed, and also makes it possible to improve the durability of the solar power generation system 10.

[0054] In the example shown in FIG. 11 , each of the multiple solar panels 100 is half the size of the solar panel 100 in the example shown in FIG. 10 , there are two solar panels 100, there is one separating portion 202, and the type of panel mounting fixture 200 used is a panel mounting fixture 200 with a structure similar to that of the pocket portion 240 in the example shown in FIG. 10 , but this is not limited to this. For example, the size of the solar panel 100 may be any size, the number of multiple solar panels 100 may be three or more, the number of separating portions 202 may be two or more, and the type of panel mounting fixture 200 may be a type other than the pocket portion 240. The separating portion 202 may have a structure that allows wind and rain to pass through easily. For example, the separating portion 202 may have a mesh structure.

[0055] Fig. 12 schematically illustrates an example of a solar power generation system 10. In Fig. 12, differences from the example illustrated in Fig. 1 will be mainly described, and descriptions of commonalities with the example illustrated in Fig. 1 will be omitted.

[0056] In the example shown in FIG. 12 , the solar power generation system 10 further includes an attachment adjustment jig 32 attached to one end of the panel mounting curtain 300 and configured to adjust the mounting angle 34 of the panel mounting curtain 300. In the example shown in FIG. 12 , the solar power generation system 10 is fixed to a structure 36. The structure 36 may be, for example, a handrail on the roof of a building, the frame of various facilities, or the frame of the building. For example, if snow falls while the solar power generation system 10 is installed so that the surface of the panel mounting curtain 300 is horizontal, the weight of the snow accumulated on the solar power generation system 10 may damage the solar power generation system 10. Snow accumulated on the solar power generation system 10 may block sunlight 92, significantly reducing power generation efficiency until the snow melts. In response to this, as shown in the example shown in FIG. 12 , the attachment adjustment jig 32 can adjust the mounting angle 34, making it easier for snow to fall off the solar power generation system 10, thereby reducing the impact of snow accumulation. The mounting adjustment jig 32 may adjust the mounting angle 34 and / or mounting direction of the solar panel 100 by adjusting the mounting angle 34 and / or mounting direction of the panel mounting screen 300. For example, by using the mounting adjustment jig 32 to orient the solar panel 100 at an angle and direction appropriate for the installation location of the solar power generation system 10, the power generation efficiency of the solar panel 100 can be improved. For example, the direction appropriate for the installation location of the solar power generation system 10 may be south if the installation location is in the Northern Hemisphere. The angle appropriate for the installation location of the solar power generation system 10 may be an angle appropriate for the latitude of the installation location.

[0057] 13 is an explanatory diagram illustrating a case where the solar power generation system 10 is installed in an air conditioning outdoor unit 400. The air conditioning outdoor unit 400 exchanges heat with an air conditioning indoor unit (not shown). The air conditioning outdoor unit 400 and the air conditioning indoor unit exchange heat to regulate the temperature of the room in which the air conditioning indoor unit is located. In this embodiment, a case where indoor cooling is achieved by the air conditioning outdoor unit 400 and the air conditioning indoor unit will be mainly described, but heating may also be achieved.

[0058] The air conditioning outdoor unit 400 has an air intake 414 and an air exhaust 416. The air intake 414 is disposed on the bottom surface 404 of the housing 402. Note that, although an example is shown here in which the air intake 414 is disposed only on the bottom surface 404, this is not limiting, and the air intake 414 may be disposed on at least one of the four side surfaces 408 of the housing 402. Furthermore, the air intake 414 may be disposed on at least one of the four side surfaces 408 of the housing 402 and on the bottom surface 404 of the housing 402.

[0059] Exhaust port 416 is arranged on top surface 406 of housing 402. Air conditioning outdoor unit 400 also has exhaust fan 417. When exhaust fan 417 is driven, air is taken in through intake port 414 and the air is exhausted through exhaust port 416.

[0060] 13, the solar power generation system 10 may be disposed between two air conditioning outdoor units 400. The solar power generation system 10 may be disposed by fixing the fixing portion 320 of the panel mounting screen 300 to the air conditioning outdoor unit 400. The solar power generation system 10 is disposed between the exhaust port 416 and the intake port 414. The space between the exhaust port 416 and the intake port 414 may be on the path along which air discharged from the exhaust port 416 is taken into the intake port 414 when the solar power generation system 10 is not disposed. The solar power generation system 10 can prevent air discharged from the exhaust port 416 from being taken into the intake port 414.

[0061] The panel mounting curtain 300 may be positioned so that the exhaust air flow 30 from the exhaust port 416 does not pass between the panel mounting curtain 300 and the air conditioning outdoor unit 400, or so that the amount of the exhaust air flow 30 that passes through is reduced. For example, the solar power generation system 10 is positioned between two air conditioning outdoor units 400, has a length substantially the same as the distance between the two air conditioning outdoor units 400, and is positioned at substantially the same height as the upper surfaces 406 of the air conditioning outdoor units 400. This prevents the exhaust air flow 30 from passing between the panel mounting curtain 300 and the air conditioning outdoor units 400 and being taken in through the air intake port 414. The panel mounting curtain 300 may be a sunshade that suppresses sunlight 92 from entering the air intake port 414.

[0062] Note that "substantially the same length as the distance between the two air conditioning outdoor units 400" may be a length shorter than the distance between the two air conditioning outdoor units 400, as long as the panel mounting curtain 300 can be placed between the two air conditioning outdoor units 400. Furthermore, "substantially the same height as the top surface 406 of the air conditioning outdoor units 400" may be a height at which the bottom surface of the panel mounting curtain 300 is not positioned above the top surface 406. By positioning the panel mounting curtain 300 at substantially the same height as the top surface 406 of the air conditioning outdoor units 400, it is possible to prevent the exhaust air flow 30 from being drawn in through the air intake 414, and also to prevent sunlight 92 from being blocked by the air conditioning outdoor units 400 from entering the solar panel 100.

[0063] The power generated by the solar power generation system 10 may be supplied to the air conditioning outdoor unit 400. For example, the power generated by the solar power generation system 10 is supplied to a drive unit that drives the exhaust fan 417. This can improve the air conditioning efficiency. The power generated by the solar power generation system 10 may also be supplied to a building or the like in which an air conditioning system including the air conditioning outdoor unit 400 and an air conditioning indoor unit is installed.
