Description

  The present invention relates to a durability test device for a solar cell module, and more particularly, a device for testing the durability of a solar panel mounted with a roof-standing installation method against wind, snow, static load or ice load. It is about.

  Usually, when installing a solar cell module in a roof, in order to suppress the temperature rise of a solar cell module and to improve workability, it installs with a space | interval of about 5-10 cm between a roof and a solar cell. A recent roof generally has a structure in which a waterproof rubber sheet is provided on the upper surface of a base plate, and a roof material such as a color vest is laid thereon. In the past, Japanese tile roofing was only a method of earthing, in which underlaying material was drawn on the top surface of the base plate, and soil and tiles were fixed in close contact with it. For the purpose of reducing the weight, a so-called “hanging-barrel roofing method” is often employed in which the soil is not used, but instead the tile pier is struck on the base plate and the hook claws provided on the back of the tile are hooked on the tile pier.

  In order to install a solar cell module on such a roof, a long vertical beam or a fixing bracket is passed through the roof material at a predetermined interval with the roof material remaining, and is screwed to the base plate, and the vertical beam member Alternatively, a structure in which a horizontal beam member is installed on the fixing bracket at regular intervals and a frame provided around the solar cell module is attached to the horizontal beam member is generally used.

  For example, Patent Document 1 discloses a solar cell module mounting structure including a solar cell module main body and a first frame body and a second frame body provided on two opposing sides of the solar cell module main body. The solar cell modules are arranged on the roof so that the first frame and the second frame are adjacent to each other, and the solar cell module is fixed on the roof in an upper portion of the first frame. And a locking portion for locking the solar cell module on the roof is provided at a lower portion of the second frame body, and the first frame of the solar cell modules adjacent to each other is provided. A convex member fixed on the roof is disposed between the body and the second frame, the first frame is disposed on one side of the convex member, and the second frame is disposed on the convex Arranged on the upper surface of the member, between the first frame and the second frame. A solar cell module mounting structure is disclosed in which a difference is formed, and the fixing portion of the first frame body and the locking portion of the second frame body are fixed or locked to the convex member by a common pressing member. . Here, a third frame and a fourth frame are provided on the left and right sides of the solar cell module main body, and the plurality of solar cell modules are arranged on the roof so that the third frame and the fourth frame are adjacent to each other. Are formed in respective portions of the third frame body and the fourth frame body facing each other, and a seal member is inserted into the groove of the third frame body and the groove of the fourth frame body. ing.

  Incidentally, there is an international standard IEC 61646 mechanical load test as a durability test of a solar cell module. This IEC standard test method is defined as follows. When mounting the module with a structure that can be mounted face up and face down, use the worst case that maximizes the distance between the fixed points. As the load, a load corresponding to 2400 Pa is gradually and gradually applied to the front, and this load is maintained for 1 hour. The same load is applied to the back of the module without removing the module from the rigid structure. The pressurizing step repeats the 1 hour load for 3 cycles. When checking the durability of the module against heavy accumulation of snow and ice, the load applied to the front of the module during this test is increased from 2400 Pa to 5400 Pa. That's it.

  That is, the test method of the IEC standard is performed by attaching a solar cell module vertically to a rigid structure and applying a mechanical load from the front and back of the solar cell module. The usage pattern is different and it is difficult to say that the usage environment has been reproduced. In addition, it is impossible to test the durability of the frame body and the support fitting for attaching the solar cell module to the roof.

  However, although various test methods and test apparatuses for testing the electrical characteristics of the solar cell module are provided, the mechanical strength and durability of the solar cell module, and the solar cell module using a frame or a support metal A test method and a test apparatus for testing the durability in an environment close to the actual use state attached to the PC are not yet provided. Previously, there was no common durability test method or equipment, and solar cell module manufacturers and home construction companies conducted their own tests, so there was a problem that there was no objectivity and that other companies' products could not be compared. It was.

JP 2007-231514 A

  Therefore, in view of the above-mentioned situation, the present invention intends to solve the mechanical strength and durability of the solar cell module, and the actual use state in which the solar cell module is attached to the roof using a frame body and a support metal fitting.

In addition, when the cover body 4 is moved to the side so that the operation in the chamber 3 can be easily performed, an operator enters between the gantry 13 and the portal gantry 20. A sufficient passage 21 can be secured.

  As shown in FIGS. 3 and 4, the cover body 4 is provided with an air seal packing 22 around the support frame 14 of the chamber 3 when closed, and can be locked to the lower surface of the support frame 14. Are provided on both the opposite sides of the rail 19 and one side on the reverse side, and a reinforcing frame 25 provided around the cover body 4 is penetrated from above on one side on the forward side. The fixing bolt 26 is screwed to the support frame 14 with a spacer 27 interposed. Then, the cover body 4 is moved along the rails 19 and 19 to be positioned above the chamber 3, and at the same time, the locking arms 23 are locked to the lower surface of the support frame 14, and then the fixing bolt .. Are screwed into the support frame 14, and in this state, compressed air is sent from the compressor 24 installed on the portal frame 20 to the air seal packing 22, and the air seal packing 22 is expanded to expand the support frame 14. It is pressed against the sealing surface and sealed in an airtight state. The cover 4 is provided with eight observation windows 28 made of laminated glass so that the inside of the chamber 3 can be observed.

  Then, as shown in FIGS. 2 and 3, the deformation of the solar cell module 1 is measured in a traverse 29 provided between the side walls 12 and 12 of the chamber 3 inside the second pressure chamber 7. A contact-type or non-contact-type displacement meter 10 is provided. Here, the traverse 29 is movable along the side wall 12. The illustrated displacement meter 10 is a mechanical contact type, but may be a non-contact type such as a laser displacement meter.

  More specifically, the installation surface 11 of the chamber 3 allows the solar cell module 1 of various dimensions to be attached by the support means 2 corresponding thereto, and the airtightness when various members are attached to the installation surface 11. Ingenuity is given to ensure the sex. That is, as shown in FIGS. 3, 5, and 6, the installation surface 11 is formed by laminating a steel bottom plate 30 having a thickness of 19 mm and a rubber sheet 31 having a thickness of 12 mm on the upper surface so as to withstand a large pressure. In the bottom plate 30, for example, screw holes 32 are formed at lattice positions at intervals of 100 mm, and bolts 33 are screwed into all the screw holes 32 to maintain an airtight state. The rubber sheet 31 is formed with a circular hole 34 in which the head of the bolt 33 is buried at a position corresponding to the screw hole 32.

  When the seal portion 5 is to be attached, the bolt 33 at the corresponding location is removed and replaced with a long mounting bolt 35, and the horizontal fixing plate 36 provided on the seal portion 5 is placed on the rubber sheet 31. Then, a cylindrical spacer 37 is fitted into the circular hole 34 and the mounting bolt 35 is screwed into the screw hole 32 to be mounted. In this case, the rubber sheet 31 serves as a seal that maintains hermeticity, and the rubber sheet 31 is prevented from being excessively crushed by the spacer 37 to ensure mounting strength. The seal portion 5 has a structure in which a silicon packing 39 is fitted into a groove of a channel member 38 having a substantially U-shaped cross section opened upward, and an angle member is welded to a side surface of the channel member 38. A horizontal plate serves as the fixed plate 36.

  Since the support means 2 differs depending on the panel manufacturing company, it is attached to the installation surface 11 through an appropriate auxiliary means (not shown). In this case, the auxiliary means is provided with a fixing plate similar to the fixing plate 36 and is screwed into the screw hole 32 with the mounting bolt 35 and attached. The attachment structure of the support means 2 with respect to the auxiliary means is the same as the attachment structure when actually constructing on the roof. The illustrated support means 2 is composed of a base frame 40 made of an aluminum extrusion mold and pressing members 41 and 42. The holding member 41 that supports the end portion of the solar cell module 1 has a substantially L-shaped cross section, and the holding member 42 that supports the intermediate portion that connects the solar cell modules 1 and 1 has a flat plate shape. . The base frame 40 is attached to the installation surface 11 as described above, the seal portion 5 is annularly attached along the inside thereof, and a frame 43 that holds the periphery of the solar cell module 1 from above is provided as the base frame. The upper surface of the frame body 43 is pressed down and supported by placing the presser member 41 or the presser member 42 on the base frame body 40 with bolts 44. At this time, the upper end of the silicon packing 39 of the seal portion 5 is in contact with the peripheral edge of the back surface of the solar cell module 1 and is kept airtight. At this time, when the solar cell module 1 is deformed up and down, the silicon packing 39 is easily deformed accordingly while maintaining the airtight state. However, the deformation of the silicon packing 39 must be suppressed so that the airtight state can be maintained even by the pressure difference between the first pressure chamber 6 and the second pressure chamber 7. For this reason, the silicon packing 39 is fitted to the channel member 38 so as to be easily deformed in the vertical direction and difficult to be deformed in the lateral direction.

  In the above-described embodiment, the solar cell module 1 is attached to the installation surface 11 using the support means 2 alone, and the durability is tested by attaching the seal portion 5 directly to the installation surface 11 at the inner peripheral edge thereof. It is also possible to increase the number of the solar cell modules 1 or install the solar cell modules 1 of different sizes, and simultaneously perform the durability test. Of the first air supply / exhaust ports 16,..., Unused ones are covered.

  On the other hand, the embodiment shown in FIGS. 7 and 8 has a structure suitable for performing a durability test by mounting four solar cell modules 1,... . Also in this embodiment, the support means 2 and the seal portion 5 are common to the above-described embodiments. In the present embodiment, two types of flat mounting jigs 45 and 46 are used, and a narrow mounting jig 45 is provided at the end of the solar cell module 1 and a wide mounting jig 46 is provided at the center. In addition, the support means 2 is mounted thereon, and the seal portion 5 is placed and screwed to the installation surface 11 with the mounting bolt 35 simultaneously with the fixing plate 36. Since other structures are the same as those described above, the same components are denoted by the same reference numerals and description thereof is omitted.

  Further, in the embodiment shown in FIGS. 9 to 11, a dummy roof 47 is constructed on the installation surface 11, and a plurality of solar cell modules 1,... Thus, the durability test of the mounting structure for the support means 2 and the imitation roof 47 can be performed. That is, the imitation roof 47 is constructed on a part of the installation surface 11 of the chamber 3, and the single or plural solar cell modules 1,... Are implemented on the imitation roof 47 by the support means 2. The space between the inner peripheral edge of the solar cell module 1 and the imitation roof 47 is hermetically sealed with the seal portion 5, and the imitation roof is further formed from the seal portion 5 located at the outer edge of the imitation roof 47. The first pressure chamber 6 is constituted by the imitation roof 47, the surrounding seal portion 5, and the back surface of the solar cell module 1, passing through the end of 47 and reaching the installation surface 11. The remaining space formed by the chamber 3 and the cover body 4 with the sheet 48 as a part of the rigid wall is the second pressure chamber 7. In addition, when the space enclosed with the said airtight sheet | seat 48 between the said imitation roof 47 and the installation surface 11 is still atmospheric pressure, when a big pressure difference arises between the said 1st pressure chambers 6 Since the imitation roof 47 may be deformed, the imitation roof 47 can be provided with a through hole for pressure adjustment.

  More specifically, the imitation roof 47 fixes the rafters 49,... To the installation surface 11 at actual intervals using screw holes 32, mounting bolts 35, and the like, and fixes the base plate 50 on the rafters 49. Then, a waterproof rubber sheet (not shown) is provided on the upper surface of the field board 50, and a structure in which a roof material 51 such as a color vest is laid thereon is constructed. The imitation roof 47 preferably has the same structure as the actual roof, but the base plate 50 is directly fixed to the installation surface 11, the waterproof rubber sheet is omitted, and the roof material 51 is provided on the upper surface of the base plate 50. If the airtightness can be maintained even if it is sprinkled, it is considered that there is almost no influence on the durability test. Therefore, it is sufficient to construct the imitation roof 47 with at least the base plate 50 and the roof material 51.

  Then, in order to form the second pressure chamber 7, there is a strength such as a cloth campus between the periphery of the imitation roof 47 and the installation surface 11, and an airtight sheet 48 having excellent airtightness is stretched. is there. Specifically, one end of the airtight sheet 48 is fixed by being sandwiched between the fixing plate 36 of the seal portion 5 and the roof material 51, and the other end of the airtight sheet 48 is a rubber sheet at the peripheral edge of the installation surface 11. In a state of being sandwiched between the upper surface of 31 and the presser plate 52, the presser plate 52 is screwed into the screw hole 32 of the installation surface 11 with the mounting bolt 35 and fixed in an airtight state. Here, the tightly sealed airtight sheet 48 is not greatly deformed even when the pressure difference between the first pressure chamber 6 and the second pressure chamber 7 is changed, and therefore, a rigid wall that does not substantially change the capacity. It can also be considered. In addition, a metal plate can be used instead of the airtight sheet 48.

  In the case of the present embodiment, the upper end of the first air supply / exhaust means 8 penetrating the installation surface 11 is also penetrated through the imitation roof 47 in an airtight state so that the first air supply / exhaust port 16 faces the first pressure chamber 6. Not. On the other hand, the second air supply / exhaust means 9 penetrates the installation surface 11 and faces the second air supply / exhaust port 17 in the chamber 3 as described above.

  The imitation roof 47 can be replaced with ones of various structures, and the solar cell modules 1,... To be constructed thereon including the roof are reproduced in a state close to the actual environment, and the durability test of each part is performed. Since it can be performed, the device of the present invention is very versatile.
