一方、透明なＦＲＰを用いた支持体により太陽電池素子を挟むことや埋め込む方法（以下、特許文献６、非特許文献３を参照のこと）も開示されているが、モジュール製造段階でＦＲＰを硬化させる技術であり、本発明のようなモジュール（パネル）の設置にプリプレグＦＲＰシートを使用する技術は今まで知られていない。 On the other hand, a method of sandwiching or embedding a solar cell element with a support using transparent FRP (refer to Patent Document 6 and Non-Patent Document 3) is also disclosed, but FRP is cured at the module manufacturing stage. A technology that uses a prepreg FRP sheet for installing a module (panel) as in the present invention has not been known so far.
本発明が解決しようとする課題は、太陽電池モジュール(パネル)の設置の際に架台、アンカー等の穴あけ作業を不要化することにより、今まで設置が困難であった場所（設置面）にも太陽電池モジュール（パネル）を設置できるようにすることである。 The problem to be solved by the present invention is that the installation of solar cell modules (panels) eliminates the need for drilling holes for mounts, anchors, etc. It is to be able to install a solar cell module (panel).

The present invention relates to a method for installing a solar cell module (panel), wherein the solar cell module (panel) is fixed to the installation surface without using a gantry by bonding. Moreover, in the case of a flexible solar cell module (panel), since it can adhere and harden also following the curved surface and uneven surface of a to-be-adhered surface (installation surface), according to this invention, a flexible solar cell module ( By covering the surface of the panel with the prepreg FRP sheet, the solar cell module (panel) can be protected from moisture, dirt, ultraviolet rays, and physical stress after the prepreg FRP sheet is cured.

本発明によれば、設置のための架台は不要になるためフィルムや紙を基材にした太陽光発電セルを用いたモジュールの設置の場合は１平方メートル当たり２ｋｇ程度の質量とすることができる。従来の産業用太陽電池の設置技術では架台を含む質量が１平方メートル当たり３０ｋｇ程度であるために重さの都合で設置が困難であった軽量スレートやトタンの屋根にも太陽電池モジュール（パネル）を設置することが可能となる。また、本発明によれば、プリプレグＦＲＰシートは、設置の際（硬化前）は柔軟であるため曲面や凹凸のある面にも追従して、フレキシブルな太陽電池モジュール（パネル）を設置することができるため、今まで設置の対象になっていなかった場所、例えば、電柱や石垣、ダムや道路のコンクリートのり面、採石場のベンチカット残壁面、平坦な空き地等への設置も可能になる。本発明によれば、ガラス材料を使うことが躊躇される公共設備等に太陽電池モジュール（パネル）を設置することも可能になる。
本発明によれば、ガラス基材を使用した太陽電池セルを用いたモジュールの場合に、強風や雹などに対する外部応力に耐える強度の一部を、硬化したＦＲＰシートに負担させることができるため、ガラス基材を薄くして該太陽電池モジュールを軽量化することにもつながる。
According to the present invention, since a mounting base is not required, in the case of installing a module using a photovoltaic power generation cell based on a film or paper, the mass can be about 2 kg per square meter. With conventional industrial solar cell installation technology, the mass including the gantry is about 30 kg per square meter, so solar cell modules (panels) are also attached to lightweight slate and tin roofs, which were difficult to install due to the weight. It becomes possible to install. Further, according to the present invention, since the prepreg FRP sheet is flexible when installed (before curing), it can follow a curved surface or an uneven surface to install a flexible solar cell module (panel). Therefore, it is possible to install in places that have not been targeted for installation until now, such as utility poles, stone walls, concrete slopes of dams and roads, remaining walls of bench cuts in quarries, and flat open areas. According to the present invention, it is also possible to install a solar cell module (panel) in a public facility or the like where glass materials are used.
According to the present invention, in the case of a module using a solar battery cell using a glass substrate, a part of the strength that can withstand external stress against strong winds and wrinkles can be borne by the cured FRP sheet. It also leads to reducing the weight of the solar cell module by thinning the glass substrate.
太陽電池モジュール（パネル）の表面の全体を覆うためのプリプレグＦＲＰシートは、外部刺激により硬化するものであればいずれでもよいが、太陽電池の発電効率を落とさないようにするためにできるだけ透明性の高いものの使用することが望ましい。一方、太陽電池モジュール（パネル）の外周又は外周フレーム上を覆うために使用するプリプレグＦＲＰシートは透明以外のものでもよい。 The prepreg FRP sheet for covering the entire surface of the solar cell module (panel) may be any material as long as it is cured by an external stimulus, but is as transparent as possible so as not to reduce the power generation efficiency of the solar cell. It is desirable to use a high one. On the other hand, the prepreg FRP sheet used to cover the outer periphery or the outer peripheral frame of the solar cell module (panel) may be other than transparent.
使用するプリプレグＦＲＰシートは、設置後の太陽電池モジュール（パネル）の軽量化を達成すること、貼り付け後速やかに硬化反応を進行させる観点から、厚みの厚いものは適切ではない。光硬化開始剤を用いた旭化成ジオテック社により販売されるビニルエステルプリプレグＦＲＰシート（商品名：ＡＦＲシート）の例では、厚さ１ｍｍのシートで平方メートル当たり質量１．３ｋｇであるため、１０ｍｍを超えるような厚みでは軽量にならない。また、厚くなると光の深部到達量が少なくなり、熱硬化の場合には伝熱が遅くなる。したがって、使用するプリプレグＦＲＰシートの厚みは１０ｍｍ以下が好ましい。尚、本プリプレグＦＲＰシートを屋根材として又は補強材として使用する場合は、必要とする強度特性を得る必要があり、厚みは１０ｍｍを超えて使用されることもある。 As the prepreg FRP sheet to be used, a thick prepreg sheet is not appropriate from the viewpoint of achieving weight reduction of the solar cell module (panel) after installation and allowing the curing reaction to proceed promptly after being attached. In the example of the vinyl ester prepreg FRP sheet (trade name: AFR sheet) sold by Asahi Kasei Geotech using a photocuring initiator, the sheet is 1 mm thick and the mass per square meter is 1.3 kg. It doesn't become light at a thick thickness. Further, when the thickness is increased, the amount of light reaching the deep portion is reduced, and in the case of thermosetting, heat transfer is delayed. Therefore, the thickness of the prepreg FRP sheet to be used is preferably 10 mm or less. In addition, when using this prepreg FRP sheet | seat as a roofing material or a reinforcing material, it is necessary to acquire the required intensity | strength characteristic and thickness may be used exceeding 10 mm.
プリプレグＦＲＰシートに用いるラジカル硬化樹脂は、ラジカル硬化性のものであればいずれでもよく、例えば、ビス系ビニルエステル、ノボラック系ビニルエステル、オルソフタル酸系不飽和ポリエステル、イソフタル酸系不飽和ポリエステル、ビスフェノール系不飽和ポリエステル、ウレタンアクリレートなどの樹脂が用いられる。また、これらの樹脂は、必要により、スチレンモノマーやメタクリルエステルなどの反応性単量体、重合禁止剤等の各種添加剤を含んでもよい。また、太陽電池モジュール（セル）の表面の全体を覆う場合は、プリプレグＦＲＰシートは、太陽電池モジュール（パネル）を紫外線から保護するため、太陽電池モジュール（パネル）の発電に寄与しない短波長の紫外線を吸収する樹脂を用いることがより好ましい。尚、プリプレグＦＲＰシート表面にトップコート又は保護フィルムを貼る場合は、特に紫外線の吸収のない樹脂でもかまわない。 The radical curable resin used for the prepreg FRP sheet may be any radical curable resin, such as bis vinyl ester, novolac vinyl ester, orthophthalic unsaturated polyester, isophthalic unsaturated polyester, bisphenol based. Resins such as unsaturated polyester and urethane acrylate are used. In addition, these resins may contain various additives such as reactive monomers such as styrene monomers and methacrylic esters and polymerization inhibitors, if necessary. Moreover, when covering the whole surface of a solar cell module (cell), since the prepreg FRP sheet protects a solar cell module (panel) from ultraviolet rays, the short wavelength ultraviolet rays which do not contribute to the electric power generation of a solar cell module (panel). It is more preferable to use a resin that absorbs water. In addition, when a topcoat or a protective film is stuck on the surface of the prepreg FRP sheet, a resin that does not absorb ultraviolet rays may be used.
硬化を行わせるための外部刺激は特に制限されないが、可視光、紫外線、電子線、熱、電気、圧力、空気遮断等が考えられる。
光硬化を開始させる開始剤は、ラジカル重合型開始剤やカチオン重合型開始剤など、現在知られている光重合開始剤はどれでも使用することができるが、目や皮膚に障害を引き起こす遠紫外線や電子線を使用しない太陽光、メタルハライドランプ、ＵＶ−ＬＥＤ、ブラックライト蛍光灯、キセノンなどのＵＶ−Ａ領域の近紫外線又は可視光で硬化する開始剤を使用することが好ましい。
加熱反応開始剤は特に限定されないが、有機過酸化物が好ましく使用され、開始剤と促進剤、重合禁止剤との組み合わせにより、常温硬化が可能なものも含まれる。常温硬化の場合は、使用直前まで低温で貯蔵・流通し、貼り付ける雰囲気温度又は被着材の表面温度で硬化反応する前記組み合わせが望ましい。また、外気温では反応せず、太陽電池モジュール（パネル）にダメージを与えない温度の温風又は蒸気の吹き付けにより硬化させる開始剤、促進剤及び重合禁止剤を用いれば、貯蔵・流通の際、低温に保持する必要がなくなる。
The external stimulus for curing is not particularly limited, but visible light, ultraviolet light, electron beam, heat, electricity, pressure, air blocking, and the like are conceivable.
As the initiator for initiating photocuring, any of currently known photopolymerization initiators such as radical polymerization initiators and cationic polymerization initiators can be used, but far ultraviolet rays that cause damage to the eyes and skin are used. It is preferable to use an initiator that is cured by near-ultraviolet rays or visible light in the UV-A region, such as sunlight, metal halide lamps, UV-LEDs, black light fluorescent lamps, and xenon that do not use an electron beam.
The heating reaction initiator is not particularly limited, but an organic peroxide is preferably used, and includes those that can be cured at room temperature by a combination of an initiator, an accelerator, and a polymerization inhibitor. In the case of room temperature curing, the above combination is preferred in which it is stored and distributed at a low temperature until just before use, and the curing reaction is carried out at the atmosphere temperature or surface temperature of the adherend. In addition, when using initiators, accelerators and polymerization inhibitors that are cured by spraying warm air or steam at a temperature that does not react at the outside air temperature and does not damage the solar cell module (panel), There is no need to keep it at a low temperature.
剥離紙又は剥離フィルムは、粘着性のある樹脂に対しても剥離性がよい材質、例えばポリオレフィン系フィルムや樹脂面側にシリコンの離型剤を塗布した紙やフィルムを使用することができる。また、表面保護フィルムの表側に剥離性を持たせることにより剥離フィルムの代用として用いることができ、貯蔵・流通時に該太陽電池モジュールをロール状又は積層状で取り扱うこともできる。
ラジカル硬化型樹脂には、耐火性その他物性向上のためフィラーを添加してもよい。
The release paper or release film may be made of a material having good releasability with respect to an adhesive resin, for example, a polyolefin film or a paper or film in which a silicone release agent is applied to the resin surface side. Moreover, it can use as a substitute of a peeling film by giving peelability to the front side of a surface protection film, and can also handle this solar cell module in roll shape or laminated | stacked shape at the time of storage and distribution | circulation.
In order to improve fire resistance and other physical properties, a filler may be added to the radical curable resin.
