特開２００６−３２９７８号公報JP 2006-32978 A

本発明は、フレームレス太陽電池モジュールの角部に任意に着脱可能に装着したカバーにより、製造後に施工位置へ搬入するまでの間、フレームレス太陽電池モジュールに生じる損傷を低減することを目的とする。   It is an object of the present invention to reduce damage caused to a frameless solar cell module until it is carried into a construction position after manufacture by a cover that is arbitrarily detachably attached to a corner portion of the frameless solar cell module. .

本発明は、矩形状であり、端部にフレームが設けられていない太陽電池モジュールの角部に着脱可能に装着され、前記角部を覆う側壁部および前記角部を支持する支持部を有するカバーと、前記カバーを、前記太陽電池モジュールに装着する装着手段と、を含み、前記支持部には、前記太陽電池モジュールの前記角部から該太陽電池モジュールの中心部へ向かう方向に延びる切欠きが形成され、前記装着手段は、前記角部と前記カバーとが接触しない状態で前記太陽電池モジュールを吸着可能な吸着パッドと、前記吸着パッドの頂部から突出する軸部であって、前記支持部の前記切欠きに挿入される軸部と、前記軸部の、前記吸着パッドに連なる端部とは反対側の端部に形成される抜止め部であって、前記支持部の、前記太陽電池モジュールに臨む面とは反対側の面に当接する抜止め部と、から構成される吸盤である。 The present invention has a rectangular shape and a cover that is detachably attached to a corner portion of a solar cell module that is not provided with a frame at an end portion, and includes a side wall portion that covers the corner portion and a support portion that supports the corner portion. When, the cover, seen including and a mounting means for mounting the solar cell module, wherein the support portion is a notch extending from the corner of the solar cell module in the direction toward the center of the solar cell module The mounting means is a suction pad that can suck the solar cell module in a state where the corner portion and the cover do not contact each other, and a shaft portion that protrudes from the top of the suction pad, and the support portion A shaft portion inserted into the notch, and a retaining portion formed at an end portion of the shaft portion opposite to the end portion connected to the suction pad, the solar cell of the support portion module The facing surface is a suction cup constituted by a retained portion which abuts on the opposite side.

The state in which the cover is attached to the frameless solar cell module can be maintained from the transportation to the installation after the manufacture, thereby reducing the damage to the frameless solar cell module.

（第１の実施形態）
図１は本発明の第１の実施形態のフレームレス太陽電池モジュールの保護部材１を用いた梱包部材２の一部の断面図であり、図２は図１に示す保護部材１の斜視図であり、図３は梱包部材２によって複数のフレームレス太陽電池モジュール３が梱包された状態を示す斜視図である。 (First embodiment)
FIG. 1 is a partial cross-sectional view of a packaging member 2 using a protective member 1 of a frameless solar cell module according to a first embodiment of the present invention, and FIG. 2 is a perspective view of the protective member 1 shown in FIG. FIG. 3 is a perspective view showing a state in which a plurality of frameless solar cell modules 3 are packed by the packing member 2.

第１の実施形態の保護部材１は、矩形状の複数のフレームレス太陽電池モジュール３の角部４に着脱可能に装着される。保護部材１は、各角部４を支持する支持部５に角部４の側面を覆う側壁部６が一体的に形成されるカバー７と、カバー７を角部４に装着された状態に保持するための装着手段である吸着部材８とを含む。   The protection member 1 of the first embodiment is detachably attached to the corners 4 of a plurality of rectangular frameless solar cell modules 3. The protection member 1 holds a cover 7 in which a side wall portion 6 that covers the side surface of the corner portion 4 is integrally formed on a support portion 5 that supports each corner portion 4, and the cover 7 is attached to the corner portion 4. And an adsorbing member 8 which is a mounting means.

カバー７の側壁部６は、直角に連なる一対の側壁部分１１ａ，１１ｂから成り、これらの側壁部分１１ａ，１１ｂが連なる交差部分１２には、棒材１３が挿通する挿通孔１４が形成される。各側壁部分１１ａ，１１ｂより支持部５が一体的に形成される。支持部５は、各側壁部分１１ａ，１１ｂに略垂直であって、略中央部には吸着部材８を取付けるための取付孔１５と、この取付孔１５から外周面に連なって切欠き１６が形成される。このようなカバー７を形成するのに適したものとしてはエポキシ樹脂やポリフェニレンエーテル樹脂などの樹脂材料がある。これらの樹脂材料は、軽量で、加工が容易で、ガラス基板より硬度が低いため、ガラス基板２２を傷つけにくい。   The side wall portion 6 of the cover 7 is composed of a pair of side wall portions 11a and 11b that are connected at right angles, and an insertion hole 14 through which the bar 13 is inserted is formed in the intersecting portion 12 where the side wall portions 11a and 11b are connected. The support portion 5 is integrally formed from the side wall portions 11a and 11b. The support portion 5 is substantially perpendicular to each of the side wall portions 11a and 11b, and has a mounting hole 15 for mounting the adsorption member 8 in a substantially central portion, and a notch 16 formed from the mounting hole 15 to the outer peripheral surface. Is done. Suitable materials for forming the cover 7 include resin materials such as epoxy resin and polyphenylene ether resin. These resin materials are lightweight, easy to process, and less hard than the glass substrate, so that the glass substrate 22 is hardly damaged.

吸着部材８は、フレームレス太陽電池モジュール３のガラス基板２２に吸着する吸着パット１７と、吸着パット１７の頂部から突出する軸部１８と、軸部１８の遊端部に一体的に形成され、取付孔１５よりも大径の抜止め部１９とを有する。このような吸着部材８は、吸盤とも呼ばれ、軸部１８を切欠き１６を介して取付孔１５に嵌着することによって、抜止め部１９が支持部５の裏面に当接することで抜け止めとなる。吸着パット１７は、フレームレス太陽電池モジュール３の角部４が収容される収容空間に臨んで配置され、ガラス基板２２の角部４に気密的に吸着することができる。仮に輸送時の振動などにより、角部４から吸着パット１７が離脱しても、フレームレス太陽電池モジュール３の自重により再び吸着する。また、吸着パット１７に設けられた突起部１６を引くことで、ガラス基板２２を傷つけることなく、容易に取り外すことができる。したがって吸着部材８はフレームレス太陽電池モジュール３を真空吸着して取り外し可能に保持し、輸送中の振動などによって角部４から離脱しにくい。   The adsorption member 8 is formed integrally with an adsorption pad 17 that adsorbs to the glass substrate 22 of the frameless solar cell module 3, a shaft portion 18 that protrudes from the top of the adsorption pad 17, and a free end portion of the shaft portion 18, A retaining portion 19 having a larger diameter than the mounting hole 15 is provided. Such an adsorbing member 8 is also called a suction cup, and the retaining portion 19 abuts against the back surface of the support portion 5 by fitting the shaft portion 18 into the mounting hole 15 through the notch 16, thereby preventing the suction member 8 from coming off. It becomes. The suction pad 17 is disposed facing the accommodation space in which the corner portion 4 of the frameless solar cell module 3 is accommodated, and can be adsorbed airtight to the corner portion 4 of the glass substrate 22. Even if the suction pad 17 is detached from the corner 4 due to vibration during transportation, it is again attracted by the weight of the frameless solar cell module 3. Further, by pulling the protrusion 16 provided on the suction pad 17, it can be easily removed without damaging the glass substrate 22. Accordingly, the adsorbing member 8 holds the frameless solar cell module 3 in a vacuum-removable manner, and is difficult to be detached from the corner portion 4 due to vibration during transportation.

このような吸着部材８を形成するのに適したものとしては、シリコーンゴムやポリ塩化ビニルなどの軟質合成樹脂がある。軟質合成樹脂は、振動を吸収するため、吸着部材８がフレームレス太陽電池モジュール３とカバー７の間に挟まれることで輸送時の振動を吸収することができるというメリットがある。フレームレス太陽電池モジュール３には、太陽電池素子３を結線する半田付け部や脆性の太陽電池素子などが含まれるため、振動を吸収することで、半田付け部の剥離を低減し太陽電池素子の微細な亀裂の進展を低減し、フレームレス太陽電池モジュール３の出力が低下しにくい。   Suitable materials for forming the adsorbing member 8 include soft synthetic resins such as silicone rubber and polyvinyl chloride. Since the soft synthetic resin absorbs vibration, there is an advantage that vibration during transportation can be absorbed when the adsorbing member 8 is sandwiched between the frameless solar cell module 3 and the cover 7. Since the frameless solar cell module 3 includes a soldered portion for connecting the solar cell element 3 and a brittle solar cell element, the vibration of the soldered portion is reduced by absorbing vibration, thereby reducing the solar cell element. The progress of fine cracks is reduced, and the output of the frameless solar cell module 3 is unlikely to decrease.

吸着部材８によって吸着されるフレームレス太陽電池モジュール３は、一平面上でマトリクス状に配置される複数の太陽電池素子２０を内蔵する裏面構造部２１と、裏面構造部２１の受光面側に積層されるガラス基板２２とを有し、このガラス基板２２を下方にして吸着部材８上に載置される。   The frameless solar cell module 3 adsorbed by the adsorbing member 8 is stacked on the back surface structure portion 21 including a plurality of solar cell elements 20 arranged in a matrix on one plane, and on the light receiving surface side of the back surface structure portion 21. The glass substrate 22 is placed on the suction member 8 with the glass substrate 22 facing downward.

このような保護部材１は、フレームレス太陽電池モジュール３の４つの角部４にそれぞれ装着される。図３に示されるように、保護部材１を装着したフレームレス太陽電池モジュール３は、パレット２３上に相互に間隔をあけて平行に積層された状態で載置される。このような間隔は、フレームレス太陽電池モジュール３が輸送の振動により撓む距離以上をとることで、フレームレス太陽電池モジュール３の破損を低減できる。一般的に、フレームレス太陽電池モジュールは、輸送時や運搬時の擦過や衝突により角部４が特に損傷を受けやすい。このため、図３に示すように角部を保護することで、太陽電池モジュールの損傷を低減しやすい。ガラス基板２２に強化ガラスが用いられている場合、強化ガラスの角部４は特に衝撃に弱く、衝撃を受けることで全体にくもの巣状の亀裂が生じる。また裏面構造部２１に裏面シートが用いられている場合、角部４から裏面シートの剥離が生じると、輸送時や運搬時に擦過や衝突を受けやすいため、剥離が進展しやすい。剥離が進展すると外観を損なうとともに、太陽電池素子２０を充填するＥＶＡが吸湿して黄変し、出力低下を生じる場合がある。このように角部４は外力を受けやすいとともに、フレームレス太陽電池モジュール３の強度の点からも弱い部分であるため優先して保護することで効率的な輸送をすることができる。さらに設置前の屋根上などへの運搬時に、フレームレス太陽電池モジュール３を一時的に壁に立てかけて保管する場合がある。このような場合であっても、角部４が吸着部材８により吸着したカバー７により保護されているため、裏面シートや充填材の剥離を防止することができる。   Such a protective member 1 is attached to each of the four corners 4 of the frameless solar cell module 3. As shown in FIG. 3, the frameless solar cell module 3 on which the protective member 1 is mounted is placed on the pallet 23 in a state of being stacked in parallel with a space between each other. Such an interval can reduce the breakage of the frameless solar cell module 3 by taking more than the distance that the frameless solar cell module 3 bends due to vibration of transportation. In general, in the frameless solar cell module, the corner portion 4 is particularly easily damaged by abrasion or collision during transportation or transportation. For this reason, as shown in FIG. 3, it is easy to reduce damage to the solar cell module by protecting the corners. When tempered glass is used for the glass substrate 22, the corner 4 of the tempered glass is particularly vulnerable to impacts, and a spider web-like crack is generated throughout the impact. Further, when a back sheet is used for the back structure portion 21, if the back sheet is peeled off from the corner portion 4, the peeling is likely to progress because it is easily subjected to scratching or collision during transportation or transportation. When the peeling progresses, the appearance is impaired, and the EVA filling the solar cell element 20 absorbs moisture and turns yellow, resulting in a decrease in output. As described above, the corner portion 4 is easily subjected to external force, and is also a weak portion from the viewpoint of the strength of the frameless solar cell module 3, so that it can be efficiently transported by preferential protection. Furthermore, the frameless solar cell module 3 may be temporarily stood against a wall during transportation to the roof before installation. Even in such a case, since the corner 4 is protected by the cover 7 adsorbed by the adsorbing member 8, it is possible to prevent peeling of the back sheet and the filler.

また、図２に示すようにカバー７は挿通穴１４が設けられている。このため複数積み重ねられたカバー７の挿通穴１４を、棒材１３が挿通することで、保護部材１を取り付けた複数のフレームレス太陽電池モジュール３を一体化することができる。また棒材１３はねじなどの固定具であってもよい。これにより棒材１３を、下方に配置される軸線方向一端部がパレット２３の上壁２４をその厚み方向に挿通して下方に突出し、ナット２５が螺着することができる。また棒材１３の上壁２４からほぼ垂直に突出する部分は、複数のカバー７の各挿通孔１４を挿通し、最上部のカバー７から突出する軸線方向他端部は、板状の押さえ片２６をその厚み方向に挿通し、ナット２７が螺着することができる。これらのナット２５，２７を締付けることによって、複数のカバー７がパレット２３の上壁２４と押さえ片２６との間で挟持され、パレット２７に固定されて、梱包される。カバー７の挿通穴１４に棒材１３を挿通して、保護材１を取り付けたフレームレス太陽電池モジュール３を一体化したことで、輸送振動による水平方向の移動を低減できる。さらに棒材１３にナット２７を螺着して上下方向を拘束したことで、輸送振動により積み重ねたカバー７が上下方向に離脱して荷崩れしにくい。   As shown in FIG. 2, the cover 7 is provided with an insertion hole 14. For this reason, the plurality of frameless solar cell modules 3 to which the protection member 1 is attached can be integrated by inserting the bar 13 through the insertion holes 14 of the plurality of stacked covers 7. The bar 13 may be a fixture such as a screw. Thereby, the axial direction one end part arrange | positioned below the bar 13 penetrates the upper wall 24 of the pallet 23 in the thickness direction, protrudes below, and the nut 25 can be screwed. Further, a portion that protrudes substantially vertically from the upper wall 24 of the bar member 13 is inserted through each insertion hole 14 of the plurality of covers 7, and the other axial end portion protruding from the uppermost cover 7 is a plate-shaped pressing piece. 26 is inserted in the thickness direction, and the nut 27 can be screwed. By tightening these nuts 25, 27, the plurality of covers 7 are sandwiched between the upper wall 24 of the pallet 23 and the pressing piece 26, fixed to the pallet 27 and packed. By moving the bar 13 through the insertion hole 14 of the cover 7 and integrating the frameless solar cell module 3 with the protective material 1 attached thereto, horizontal movement due to transportation vibration can be reduced. Further, the nut 27 is screwed onto the bar 13 to restrain the vertical direction, so that the cover 7 stacked by the transport vibration is detached in the vertical direction and is not easily collapsed.

このように各カバー７には、吸着部材８によってフレームレス太陽電池モジュール３がガラス基板２２を下方にして吸着されるので、各フレームレス太陽電池モジュール３の角部４からカバー７が離脱しにくく、輸送時などの振動によって各カバー７が角部４から離脱して荷崩れなどを生じにくい。さらにカバー７および吸着部材８は、化学変化や塑性変形を用いて装着されていないため何度も再使用可能である。そのため、フレームレス太陽電池モジュール３の輸送に必要な材料を削減できるとともに、環境に与える影響を小さくすることができる。   As described above, since the frameless solar cell module 3 is adsorbed to each cover 7 by the adsorption member 8 with the glass substrate 22 facing downward, the cover 7 is unlikely to be detached from the corner 4 of each frameless solar cell module 3. Each cover 7 is separated from the corner portion 4 due to vibration during transportation or the like, and is not likely to collapse. Furthermore, since the cover 7 and the adsorbing member 8 are not mounted using chemical changes or plastic deformation, they can be reused many times. Therefore, it is possible to reduce the material necessary for transportation of the frameless solar cell module 3 and to reduce the influence on the environment.

（第２の実施形態）
図４は本発明の第２の実施形態のフレームレス太陽電池モジュールの保護部材１ａを示す一部の断面図である。なお、前述の実施の形態と対応する部分には、同一の参照符を付す。第２の実施形態では、カバー７をフレームレス太陽電池モジュール３の角部４に装着された状態に保持する装着手段として、カバー７の支持部５とフレームレス太陽電池モジュール３の角部４とを着脱可能に接合する接着性材料であるホットメルト接着剤が用いられ、フレームレス太陽電池モジュール３の角部４は、接着剤層３０により支持部５に接着される。 (Second Embodiment)
FIG. 4 is a partial cross-sectional view showing the protective member 1a of the frameless solar cell module according to the second embodiment of the present invention. Note that portions corresponding to those of the above-described embodiment are denoted by the same reference numerals. In the second embodiment, as mounting means for holding the cover 7 in a state of being mounted on the corner 4 of the frameless solar cell module 3, the support 5 of the cover 7 and the corner 4 of the frameless solar cell module 3 A hot melt adhesive, which is an adhesive material that detachably attaches to each other, is used, and the corner 4 of the frameless solar cell module 3 is bonded to the support 5 by the adhesive layer 30.

このような接着剤層３０は、フレームレス太陽電池モジュール３と支持部５とに接着されており、フレームレス太陽電池モジュール３の運搬中などに振動が作用してもフレームレス太陽電池モジュール３のガラス基板２２から剥離しにくい。また接着剤層３０はガラスより樹脂に対する接着力が大きいため、ガラス基板２２よりカバー７に対する接着力が大きい。このため、施工現場等で接着剤層３０を取外す必要が生じた際に、フレームレス太陽電池モジュール３の面方向に沿って矢符Ｆで示すように、工具などによって衝撃力を与えることによって、接着剤層３０をカバー７の方に残留させ、フレームレス太陽電池モジュール３に接着剤層を残すことなく分離することができる。   Such an adhesive layer 30 is bonded to the frameless solar cell module 3 and the support 5, and even if vibration is applied during transportation of the frameless solar cell module 3, It is difficult to peel off from the glass substrate 22. Further, since the adhesive layer 30 has a higher adhesive force to the resin than glass, the adhesive layer 30 has a higher adhesive force to the cover 7 than the glass substrate 22. For this reason, when it becomes necessary to remove the adhesive layer 30 at a construction site or the like, by applying an impact force with a tool or the like as indicated by an arrow F along the surface direction of the frameless solar cell module 3, The adhesive layer 30 remains on the cover 7 and can be separated without leaving the adhesive layer on the frameless solar cell module 3.

このような接着剤層３０は、例えば、ホットメルト接着剤、エポキシ接着剤、フェノール樹脂接着剤などのガラス用接着剤からなる。ホットメルト接着剤が用いられた場合は、固化後に粘着性を有しないため、フレームレス太陽電池モジュール３との分離後にガラス基板２２に残らず、作業性に優れるという効果がある。エポキシ接着剤は、溶剤を含有せず、接触圧によって室温で硬化し、透明性が高く、低収縮性であるので、ガラスの接着に好ましい。またフェノール樹脂接着剤は、耐熱性および耐水性に優れ、太陽電池モジュールの屋外での保管に対して耐性が高く、この点で長期にガラス基板２２にカバー７を接着させたいときには、高い信頼性を実現することができる。   Such an adhesive layer 30 is made of, for example, an adhesive for glass such as a hot melt adhesive, an epoxy adhesive, or a phenol resin adhesive. When a hot melt adhesive is used, since it does not have adhesiveness after solidification, it does not remain on the glass substrate 22 after separation from the frameless solar cell module 3 and has an effect of excellent workability. The epoxy adhesive does not contain a solvent, is cured at room temperature by contact pressure, has high transparency, and is low in shrinkage, and thus is preferable for glass adhesion. In addition, the phenol resin adhesive is excellent in heat resistance and water resistance, and has high resistance to outdoor storage of the solar cell module. In this regard, when the cover 7 is to be bonded to the glass substrate 22 for a long period of time, high reliability is obtained. Can be realized.

（第３の実施形態）
図５は本発明の第３の実施形態のフレームレス太陽電池モジュールの保護部材１ｂを示す斜視図である。なお、前述の実施の各形態と対応する部分には、同一の参照符を付す。本実施の形態の太陽電池モジュールの保護部材１ｂは、カバー７を角部４に装着した状態に保持する装着手段として、フレームレス太陽電池モジュール３の４つの各角部４にそれぞれ装着されたカバー７を、対角線方向に相互に連結する線状部材である紐３１ａ，３１ｂが用いられる。 (Third embodiment)
FIG. 5 is a perspective view showing the protective member 1b of the frameless solar cell module according to the third embodiment of the present invention. Note that portions corresponding to those of the above-described embodiments are denoted by the same reference numerals. The protection member 1b of the solar cell module according to the present embodiment is a cover mounted on each of the four corners 4 of the frameless solar cell module 3 as mounting means for holding the cover 7 in a state of being mounted on the corner 4. Strings 31a and 31b, which are linear members that connect 7 to each other diagonally, are used.

各紐３１ａ，３１ｂは、フレームレス太陽電池モジュール３の各角部４にそれぞれ装着されたカバー７のうち、対角線方向に配置される各一対のカバー７同士を結束し、角部４からの離脱を低減する。このようなカバー７には、各紐３１ａ，３１ｂの各両端部を結束するために、側壁部６の上部に支持部５と平行に延びる上壁部３２が一体的に形成され、各上壁部３２には各紐３１ａ，３１ｂの各両端部をそれぞれ挿通して結束するための挿通孔３３が形成される。   The cords 31 a and 31 b bind the pair of covers 7 arranged in the diagonal direction among the covers 7 attached to the corners 4 of the frameless solar cell module 3, and detach from the corners 4. Reduce. In such a cover 7, an upper wall portion 32 extending in parallel with the support portion 5 is integrally formed on the upper portion of the side wall portion 6 in order to bind both ends of the strings 31 a and 31 b, and each upper wall The part 32 is formed with an insertion hole 33 for inserting and binding the both ends of the strings 31a and 31b.

このように紐３１ａ，３１ｂによって、各カバー７を対角線方向に結束することによって、輸送時に角部４からカバー７が振動によって離脱しにくくできるとともに、現場で設置する際には、各紐３１ａ，３１ｂを鋏などの切断工具によって切断し、あるいはカバー７の上壁部３２への結束状態を解除することによって、角部４から各カバー７を容易に離脱させることができる。   Thus, by binding each cover 7 diagonally by the strings 31a and 31b, the cover 7 can be made difficult to be detached from the corner 4 by vibration at the time of transport. Each cover 7 can be easily detached from the corner portion 4 by cutting 31b with a cutting tool such as a scissors or by releasing the binding state of the cover 7 to the upper wall portion 32.

In the fourth embodiment of the present invention, instead of the strings 31a and 31b of the third embodiment, a linear member having elasticity such as a synthetic resin tape or a rubber band is used and arranged in a diagonal direction. The respective covers 7 to be connected are connected.

弾性の線状部材は振動を吸収可能であるため、輸送時の振動により各角部４の結束が緩みにくい、つまりガタツキが大きくなりにくく、各カバー７が離脱するのを低減することができる。またフレームレス太陽電池モジュール３を設置するときには、各カバー７の線状部材による連結を前述の切断工具などにより容易に解除して、各カバー７を各角部４から取外すことができる。   Since the elastic linear member can absorb vibration, it is difficult to loosen the binding of the corner portions 4 due to vibration during transportation, that is, the backlash is less likely to increase, and the cover 7 can be prevented from being detached. Further, when installing the frameless solar cell module 3, the connection of the covers 7 by the linear members can be easily released by the above-described cutting tool or the like, and the covers 7 can be removed from the corners 4.
