Description

  The present invention relates to a solar light utilization system, a solar cell panel installation stand, and a solar cell panel installation method, and more particularly, solar light utilization for improving energy efficiency in a building using solar power generation and heat collection. About the system.

  Since solar power generation using solar cells does not generate carbon dioxide, it is attracting attention as an energy source considering prevention of global warming. In particular, high-efficiency houses that supply most (or all) of the electricity used in the home by solar cell panels installed on the roof or roof are widespread. In addition, a system is known in which heat from sunlight is collected on a roof, and this is taken into a building and used for room heating or hot water supply.

  In recent years, hybrid solar power utilization systems combining the above-described solar power generation and solar heat recovery technology have begun to be used. For example, Japanese Patent Laid-Open No. 9-184209 describes a technique for drawing air that has passed through a ventilation layer for cooling a solar cell module into a building by a blower fan (see Patent Document 1). This ventilation layer is formed between the solar cell module and the roof. The air passing through the ventilation layer collects heat from the solar cell module and the roof heated by sunlight, and is supplied into the building.

  In such a sunlight utilization system, the following effects can be obtained. That is, (1) by recovering heat from the solar cell, it is possible to prevent a decrease in power generation efficiency due to a temperature rise. (2) The recovered solar heat can be used for heating and supplying the living space. Therefore, by combining solar power generation and solar heat recovery technology, the solar energy acquisition efficiency can be maximized, unlike when the system is individually installed on the roof surface.

  In a hybrid solar light utilization system, it is necessary to secure a flow path (ventilation layer) through which air flows between the solar cell and the roof. In order to recover heat more efficiently and supply it to the house, it is important to improve the heat insulation of the flow path. For example, in the case of a system having a structure in which a roof and a solar cell are integrated, it is relatively easy to improve the heat insulation of the flow path by designing to seal a portion other than the air intake (or discharge). It becomes possible.

  However, when the roof and the solar cell are integrated, a lot of man-hours are required for installing the roof, and a lot of time and cost are also required for solar cell replacement and roof maintenance. . On the other hand, the retrofitting method in which the solar cell panel is detachably installed on the roof is more advantageous than the case in which the roof and the solar cell are integrated in terms of costs such as installation and maintenance.

  Therefore, in order to realize a high-efficiency and low-cost hybrid solar power utilization system, the solar panel is simply attached to (or removed from) the roof while taking into consideration the heat insulation of the flow path for heat recovery. ) Possible technology is required.

(Configuration of solar power system)
With reference to FIG.1 and FIG.2, the structure of the sunlight utilization system by this invention is demonstrated. FIG. 1 is a diagram showing a configuration in an embodiment of a solar light utilization system according to the present invention. However, a decorative cover 16 described later is omitted in FIG.

  The solar light utilization system according to the present invention includes a solar cell panel 100 provided on a roof 20. The solar cell panel 100 is formed by a plurality of solar cell modules 1 installed on a crosspiece (end crosspiece 11 and intermediate crosspiece 12) and a module support 13 described later. The solar cell panel 100 is installed on the two end bars 11 to form the flow path 10 (crossing path 10) through which air passes between the solar panel 100 and the roof 20. Here, the end bar 11 is installed on the roof 20 with the direction connecting the main ridge side and the eaves side (hereinafter referred to as the vertical direction) as the longitudinal direction. In the space (flow channel 10) surrounded by the solar cell panel 100, the roof 20, and the end bar 11, the eaves end side is open, and the main ridge side is connected to the heat collecting unit 200. Further, on the plane formed by the roof 20, a direction perpendicular to a line connecting the main building and the eaves (hereinafter referred to as a lateral direction) is closed by the end bar 11 in the space. For this reason, the space between the solar cell panel 100 and the roof 20 forms the flow path 10 (ventilation path 10) in the vertical direction. Further, as will be described later, the space is divided in the lateral direction by an intermediate beam 12 provided between the two end beams 11. For this reason, the air that has entered the flow path 10 from the eaves side is rectified as a vertical airflow 300.

  The roof 20 includes a field board 22 and a roofing material 21 laid on the field board 22. The roofing material 21 is formed by a plurality of sheet metal members, and each of the sheet metal members is connected via a folded portion 23 extending in the lateral direction. The crosspieces (end crosspiece 11 and intermediate crosspiece 12) are installed on the roof 20 so that the longitudinal direction is the vertical direction. For this reason, the crosspieces (the end crosspieces 11 and the intermediate crosspieces 12) are installed on the roof 20 so as to cover the plurality of folded portions 23.

  The solar cell panel 100 is connected to the heat collection unit via the heat collection panel 2 formed near the main building. The airflow 300 flowing into the flow path 10 passes over the heat collection panel 2 and reaches the heat collection unit 200. The heat collecting panel 2 is installed on the roof 20, and an end bar 11 or a bar extending to the end bar 11 is installed at the end in the lateral direction. A transparent panel (not shown) is provided on the heat collection panel 2 through a space connected to the flow path 10. The transparent panel (not shown) forms a space connected to the flow path 10 by being provided on the end beam 11 or the beam extended to the end beam 11. This space connects the heat collecting unit 200 and the flow path 10. The airflow 30 warmed in the flow path 10 is further heated by sunlight in the space on the heat collection panel 2 and flows into the heat collection unit 200.

  FIG. 2 is a conceptual diagram showing an airflow 300 generated in the solar light utilization system according to the present invention. 1 and 2, the air (airflow 300) that has entered the flow path 10 from the eaves side is warmed by the solar cell panel 100 and the roof 20, and is provided on the main ridge side due to the adiabatic expansion effect. It flows into the heat unit 200. The heat collection unit 200 is provided with a vent 201, and the warmed airflow 300 flows into the building through the vent 201. The airflow 300 flowing from the vent 201 is guided to each room or under the eaves through the duct 202 in the building.

  As described above, the solar light utilization system according to the present invention efficiently converts solar energy and supplies it to the building by power generation by the solar cell panel 100 and heat recovery by the solar cell panel 100 and the roof 20. Can do.

(Configuration of solar panel installation stand)
Next, with reference to FIG. 3 to FIG. 10C, the structure of the installation base of the solar cell panel 100 will be described in detail. The main structure of the installation base of the solar cell panel 100 is a crosspiece (end crosspiece 11, intermediate crosspiece 12) and a module base 13, a module holder 14, an intermediate cover 15, a decorative cover 16 and a sheet metal base that are fixed to the roofing material 21. 17.

  FIG. 3 is a plan view showing the lowermost layer structure of the solar cell panel installation stand according to the present invention. With reference to FIG. 3, the end crosspiece 11 and the intermediate crosspiece 12 are installed on the roofing material 21 via the RA tape 32 and the crosspiece sealer 33 mentioned later. As described above, the two end bars 11 are provided on the roof material 21 substantially in parallel so that the longitudinal direction is the vertical direction. A plurality of intermediate bars 12 are provided between the two end bars 11 at equal intervals in the lateral direction. The length of the intermediate bar 12 in the longitudinal direction is preferably shorter than the length of the end bar 11 in the longitudinal direction. In this case, it is preferable that the plurality of intermediate rails 12 are arranged with a predetermined gap 18 in the vertical direction. The gap 18 can be used to pass cables connecting between the solar cell modules 1. Further, the length of the intermediate bar 12 in the longitudinal direction may be the same as that of the end bar 11. In this case, it is preferable to provide a through hole through which the cable passes through the intermediate rail 12. When the end beam 11 and the intermediate beam 12 are equal in length and the size of the through hole is small, or when the number of the gaps 18 is small (the length of the gaps 18 is short), the airflow 300 flowing in the lateral direction is reduced, A rectifying effect in the vertical direction can be expected.

  The lateral distance between the end bar 11 and the intermediate bar 12 or between the intermediate bars 12 is set according to the size of the solar cell module 1. That is, when one solar cell module 1 is arranged so as to bridge between the end beam 11 and the intermediate beam 12 or between the intermediate beams 12, the end of the solar cell module 1 is connected to the end beam 11 or the intermediate beam 12. This is the top (see FIG. 7). In the example shown in FIG. 3, four solar cell modules 1 can be arranged in the horizontal direction. Further, it is preferable that a plurality of module receiving bases 13 for indicating the solar cell module 1 are provided between the end bars 11 and the intermediate bars 12 or between the intermediate bars 12.

  It is preferable that the horizontal interval, number, or size of the module cradle 13 is set to an interval, number, or size that supports the solar cell module 1 and does not obstruct the airflow 30. Further, the vertical distance between the module bases 13 is set according to the size of the solar cell module 1. That is, when one solar cell module 1 is arranged so as to bridge in the vertical direction between the module bases 13, the end of the solar cell module 1 is on the module base 13 (see FIG. 7). In the example shown in FIG. 3, three solar cell modules 1 can be arranged in the vertical direction.

  The end bar 11, the intermediate bar 12, and the module pedestal 13 are preferably formed of a lightweight material having high corrosion resistance. Moreover, in order to be able to use also as a ground wiring of the solar cell module 1, it is preferable that these are formed with an electroconductive material. For example, the end bar 11, the intermediate bar 12, and the module base 13 are formed of an alloy containing aluminum or a similar material.

  The end bar 11 is preferably joined to the roof material 21 without a gap in order to improve heat insulation and airtightness with respect to the flow path 10. In the present invention, by inserting the RA tape 32 or the optic sealer 33 between the end beam 11 and the roofing material 21, exchange of air and heat between the flow path 10 sandwiching the end beam 11 and the outside air is prevented. Yes.

  4 is a cross-sectional view of the end bar 11 taken along the line A-A ′ shown in FIG. 3. When the end bar 11 is attached to the roofing material 21, the end bar 11 is pressed and fixed to the roofing material 21 via the crossing sealer 33 and the RA tape 32. Specifically, as shown in FIGS. 4 and 6, the end bar 11 has a connection surface 110 for connecting and fixing the end bar 11 to the roof material 21. Before attaching the end bar 11 to the roof material 21, the bar ept sealer 33 and the RA tape 32 are attached to the lower surface of the connection surface 110. The crosspiece sealer 33 is preferably attached to the entire connection surface 110. Moreover, it is preferable that the RA tape 32 is affixed to a region of the connection surface 110 where a large gap may occur when the connection surface 110 is installed on the roofing material 21.

  The roof 20 on which the solar cell panel 100 according to the present invention is installed has a folded portion 23 formed in the lateral direction. A step is generated by the roof material 21 on the main ridge side and the roof material 21 on the eaves side, with the folded portion 23 as a boundary. Since the end bar 11 has a linear structure in the longitudinal direction, a gap is generated between the end bar 11 (connection surface 110) and the roof material 21 due to a step in the peripheral region of the folded portion 23. In the present embodiment, the gap is closed by inserting the crosspiece sealer 33 between the connection surface 110 and the roofing material 21. In particular, it is preferable to insert the RA tape 32 in a region around the folded portion 23 where the gap is expected to be large so as to overlap the crosspiece sealer 33. The connecting surface 110 with the crosspiece sealant 33 and the RA tape 32 is pressed and connected to the roofing material 21 by the fixing screw 31, so that the connecting surface 110 and the roofing material 21 connect the crosspiece sealant 33 and the RA tape 32. Close through. As a result, the end crosspiece 11 can block the exchange of air and heat between the space below the solar cell panel 100 serving as the flow path 10 and the outside air. The fixing screw 31 fixes the end bar 11 to the roof 20 by being screwed to the base plate 22 through the connection surface 110 and the roof material 21.

  Further, it is preferable that the end portion of the end bar 11 is disposed in the vicinity of the folded portion 23 so that the end bar 11 is stably placed on the roof 20.

  Similarly to the end bar 11, the intermediate bar 12 is preferably fixedly attached to the roofing material 21 via a bar optic sealer 33 and an RA tape 32. The intermediate crosspiece 12 is shorter in the longitudinal direction than the end crosspiece 11, but the other configurations are the same. The intermediate crosspiece 12 is fixed by pressing and connecting the connection surface of the intermediate crosspiece 12 to the roofing material 21 with a fixing screw. Attached to the roof 20. By inserting the crosspiece optic sealer 33 or the RA tape, it is possible to prevent the airflow generated in the lateral direction via the intermediate crosspiece 12, so that the rectifying effect in the vertical direction of the airflow 300 flowing through the flow path 10 can be enhanced.

  As described above, in the present invention, the end beam 11 from the flow path 10 below the solar cell panel 100 is improved by improving the sealing degree and the heat insulating effect between the end beam 11 and the roof 20 which are installation frames of the solar cell panel 100. The heat leaking to the outside through 11 can be reduced. Thereby, it becomes possible to collect heat more efficiently. Further, the air current 300 can be effectively rectified in the vertical direction by the intermediate beam 12 serving as an installation base of the solar cell panel 100. By rectifying in the vertical direction, the air heated by the solar cell panel 100 can be efficiently taken into the heat collecting unit 200 and the building.

  Moreover, if the airflow 300 stays in the space under the solar cell panel 100, the temperature of the airflow 300 may rise more than necessary. This causes the power generation efficiency of the solar cell panel 100 to be reduced. In the present invention, since the airflow 300 is rectified in the vertical direction, there is an effect of suppressing a decrease in power generation efficiency due to an excessive temperature rise of the airflow 300.

  FIG. 5 is a plan view showing the structure of the sheet metal receiving base 17 provided on the rail of the solar cell panel according to the present invention. FIG. 6 is a cross-sectional view taken along the line B-B ′ showing the connection structure between the crosspiece and the sheet metal support 17 according to the present invention.

  Referring to FIG. 5, a sheet metal receiving base 17 for supporting the decorative cover 16 is provided on the end bar 11 and on the ends of the end bar 11 and the intermediate bar 12 on the eaves side. With reference to FIG. 6, the attachment method of the sheet metal receiving stand 17 fixed on the end crosspiece 11 is demonstrated. Two guide grooves 34 extending in the longitudinal direction are provided on the upper surface of the end bar 11. On the other hand, the sheet metal support 17 has a claw 35 that can be fitted into the guide groove 34. The claw 35 of the sheet metal receiving base 17 is fitted into the guide groove 34 on the outside air (opposite side of the solar cell panel 100), and the side face on the outside air side of the end bar 11 and the sheet metal receiving base 17 are screwed. As a result, the sheet metal support 17 is fixed to the outside air side of the end bar 11.

  Although details of the mounting method of the sheet metal receiving base 17 installed on the eaves side are omitted, they are fixedly installed so as to bridge the ends of the end beam 11 and the intermediate beam 12 on the eaves side. At this time, the sheet metal cradle 17 is installed on the module cradle 13 closest to the eaves side. Since the eaves side sheet metal pedestal 17 is bridged hollow, even if the decorative cover 16 is installed thereon, the eaves side flow path 10 is opened.

  On the other hand, since the main building side is connected to the heat collecting unit 200 via the heat collecting panel 2, the sheet metal receiving base 17 is not installed.

  As described above, the solar cell module 1 is installed on the end bar 11, the intermediate bar 12, and the module base 13 attached to the roof 20. In the present invention, as shown in FIG. 7, the solar cell modules 1 are arranged at positions defined by the end beam 11 and the intermediate beam 12, and the solar cell module 1 and the beam are pressure-bonded by the module holder 14. A solar cell module can be installed.

  As shown in FIG. 7, the module presser 14 is disposed on the crosspiece by a fixing bolt 36 provided on the end crosspiece 11, the intermediate crosspiece 12, and the module base 13 and a fixing nut 39 screwed to the fixing bolt 36. The solar cell module 1 is pressed in. Thereby, the solar cell module 1 is fixed on a mount frame.

  The fixing bolt 36 is installed on the end beam 11, the intermediate beam 12, and the module base 13 before the solar cell module 1 is arranged. The fixing bolt 36 is attached to a bolt insertion rail 40 formed on each of the end bar 11, the intermediate bar 12, and the module base 13. FIG. 8 is a view showing a bolt insertion rail 40 to which a fixing bolt according to the present invention is attached. With reference to FIG. 8 (left figure), a bolt insertion rail 40 is provided on the upper portion of the end bar 11. The bolt insertion rail 40 includes a cavity into which the head of the fixing bolt 36 is inserted, and a groove that is smaller than the diameter of the head and from which only the threaded portion of the fixing bolt 36 protrudes. The lower part of the cavity into which the head of the fixing bolt 36 is inserted is formed to support the head. The bolt insertion rail 40 is formed in a direction extending in the longitudinal direction of the end bar 11. The intermediate rail 12 is also formed with a bolt insertion rail 40 similar to the end rail 11. Further, referring to FIG. 8 (right diagram), a bolt insertion rail 40 similar to the end bar 11 is also formed on the module base 13 so as to extend in the longitudinal direction of the module base 13.

  The fixing bolt 36 is disposed at an arbitrary position in the longitudinal direction of each of the end bar 11, the intermediate bar 12, and the module by inserting the head into the bolt insertion rail 40.

  Next, a method for fixing the solar cell module 1 to the crosspiece will be described. FIG. 12 is a plan view showing the configuration of the solar cell installation stand and the solar cell panel according to the present invention that have been installed on the roof 20. With reference to FIG. 9A to FIG. 9C, a method for fixing the solar cell module 1 to the intermediate beam 12 and a structure after the fixing will be described. 9A to 9C are diagrams showing a method of fixing the solar cell module 1 according to the present invention on the intermediate beam 12. Here, the fixing method of the solar cell module 1 in the C-C 'cut surface shown in FIG. 12 is demonstrated.

  With reference to FIG. 9A, when the solar cell module 1 is arranged on the intermediate beam 12, the guide groove 34 formed on the intermediate beam 12 and the claw 37 formed on the end side portion of the solar cell module 1 are provided. Fit. Thereby, positioning at the time of installing the solar cell module 1 on a crosspiece can be performed simply. Two guide grooves 34 are formed in the intermediate beam 12 and the module cradle 13, and the claw 37 of the solar cell module 1 is fitted into each of the guide grooves 34. When the longitudinal direction of the intermediate beam 12 is installed in the vertical direction, two rows of solar cell modules 1 are arranged on the intermediate beam 12 with the intermediate beam 12 interposed therebetween. Or when the longitudinal direction of the intermediate | middle crosspiece 12 is installed in the horizontal direction, the solar cell module 1 of 2 rows is arrange | positioned on the said intermediate | middle crosspiece 12 on both sides of the intermediate | middle crosspiece 12. As shown in FIG. Thereby, when the intermediate | middle crosspiece 12 is installed in the roof 20 in the correct position, the solar cell module 1 can be easily arranged in an array form only by fitting the nail | claw 37 to the guide groove 34. FIG.

  The module presser 14 for fixing the solar cell module 1 includes a bottom surface 41 having a through hole through which the fixing bolt 36 is passed, and a press surface 42 that extends in a stepped manner with respect to the bottom surface 41. A module presser opt sealer 38 is affixed to the presser surface 42. The bottom surface 41 and the pressing surface 42 are substantially parallel, and the distance between the surfaces is from the surface on which the solar cell module 1 is placed on the intermediate beam 12 (the contact surface with the upper surface of the intermediate beam 12) to the upper surface (the pressing surface 42). Shorter than the height of the contact surface.

  With reference to FIG. 9B, the module holder 14 presses the solar cell module 1 toward the intermediate rail 12 by screwing the fixing nut 39 into the fixing bolt 36. Specifically, the module retainer 14 is close to the upper surface side of the intermediate beam 12 by bolting, and the solar cell module 1 is sandwiched between the module retainer 14 and the intermediate beam 12 to fix the solar cell module 1 to the intermediate beam 12. At this time, the module pressing opt sealer 38 affixed to the pressing surface 42 is pressed by the pressing surface 42 and is in close contact with the solar cell module 1. Thereby, the passage of air between the space below the solar cell module 1 and the outside air can be closed. For example, in the present invention, the solar cell module 1 is positioned by fitting a claw 37 into the guide groove 34. Usually, there is play between the guide groove 34 and the claw 37, which may reduce the degree of sealing of the space under the solar cell module 1. In the present invention, by pressing the solar cell module 1 with the module presser 14 to which the ept sealer is attached, the airtightness of the flow path 10 can be improved and the solar cell module 1 can be easily fixed.

  Since the solar cell module 1 arranged at the end of the solar cell panel 100 closest to the main building side and the eaves side serves as a reference when the solar cell module 1 is arranged, it can be fixed one by one in the lateral direction. Preferably it can be done. For this reason, it is preferable that the length of the module presser 14 (horizontal) on the main ridge side and eaves side in the solar cell panel 100 is a length corresponding to the lateral length of one solar cell module 1. . Further, in the intermediate region other than the main ridge side and the eaves side, the plurality of solar cell modules 1 arranged in the lateral direction of the solar cell module 1 are held by one module in order to improve the airtightness with respect to the flow path 10. 14 can be fixed. For this reason, the length of the module retainer 14 that fixes the upper and lower sides (sides of the main building side and the eaves side) of the solar cell module 1 corresponds to the total length of the plurality of solar cell modules 1 arranged in the lateral direction. It is preferable that the length be Furthermore, the length of the module presser 14 considering the most airtightness is a length corresponding to the length of the entire solar cell panel 100 in the lateral direction. However, when considering the ease of installation of the solar cell module 1, the length of the module presser 14 that fixes the upper and lower sides of the solar cell module 1 in the intermediate region is a length that can fix the solar cell module 1 by a predetermined number. It is preferable to set to.

  Similarly, in order to improve the airtightness with respect to the flow path 10, it is preferable that a plurality of solar cell modules 1 arranged in the vertical direction of the solar cell module 1 can be fixed by one module presser 14. For this reason, it is preferable that the length of the module presser 14 that fixes the left and right sides of the solar cell module 1 corresponds to the total length of the plurality of solar cell modules 1 arranged in the vertical direction. Furthermore, the length of the module presser 14 considering the most airtightness is a length corresponding to the length of the entire solar cell panel 100 in the vertical direction. However, when considering the ease of installation of the solar cell module 1, the length of the module holder 14 that fixes the left and right sides of the solar cell module 1 in the intermediate region is a length that can fix the solar cell module 1 by a predetermined number. It is preferable to set to.

  With reference to FIG. 9B and FIG. 9C, the decorative cover 16 is attached on the module presser 14 in order to blind the fixing bolt 36 and the fixing nut 39 for fixing the module presser 14.
