Abstract

PROBLEM TO BE SOLVED: To provide an inspection method capable of inspecting a solar cell array on the rooftop of a building with a narrow auxiliary space, a solar cell array in a large-scaled power generation system using a number of solar cell modules over a wide area or installed at a high place or in a wide area or a solar cell array installed on the roof of a relatively small-scaled individual house, even in the case where a special camera cannot be disposed from the ground since an interval to a neighboring house is narrow.SOLUTION: The solar cell array is inspected by a radio control helicopter on which a special camera is installed, while disposing the camera at any suitable position.

Description

本発明は、太陽電電池アレイの検査装置および太陽電池アレイの検査方法に関する。  The present invention relates to a solar cell array inspection apparatus and a solar cell array inspection method.

従来、太陽電池モジュールを屋外に設置し発電する太陽光発電システムにおいては、複数の太陽電池モジュールから構成される太陽電池アレイがビル屋上や個人住宅の屋根などの高所に設置される場合が多く、２０年もの長期の特性保証のため、システム全体の出力が低下した際、太陽電池モジュールを一つ一つ屋根等から取り外しＥＬ（ｅｌｅｃｔｒｏｌｕｍｉｎｅｓｃｅｎｃｅ）などの評価のテストをしなければ、不良モジュールを特定することが出来ず、長期保証をするビジネスの足かせとなっていた。  Conventionally, in a solar power generation system in which a solar cell module is installed outdoors to generate power, a solar cell array composed of a plurality of solar cell modules is often installed at a high place such as a roof of a building or a roof of a private house. In order to guarantee the long-term characteristics of 20 years, when the output of the entire system is reduced, the defective modules are identified unless the solar cell modules are removed from the roof etc. and tested for evaluation such as EL (electroluminescence). It was not possible to do so, and it was a drag on business for long-term guarantees.

近年、太陽電池アレイの検査のため、モジュールを一つ一つ取り外すことなく、不良モジュールを特定する方法として、雑誌“Ｐｈｏｔｏｎ Ｉｎｔｅｒｎａｔｉｏｎａｌ １−２０１３”Ｐ７８〜Ｐ８０にＤａｙＳｙやＬｕｍｉＳｏｌａｒＯｕｔｄｏｏｒなどのブランド名で紹介されているように、ＰＬ（Ｐｈｏｔｏｌｕｍｉｎｅｓｃｅｎｃｅ）やＥＬ（Ｅｌｅｃｔｒｏｌｕｍｉｎｅｓｃｅｎｃｅ）の画像を特殊カメラで太陽電池アレイを撮影する方法がある。また、“太陽光発電システムの不具合事例ファイル”（加藤和彦著）Ｐ３７〜Ｐ３８には赤外線カメラによる観察も紹介され、また、特開２０１３−３６７４７には、太陽電池アレイのどの位置の太陽電池モジュールがどの程度出力低下しているかを判断する方法が紹介されている。  In recent years, it has been introduced in magazines “Photo International 1-2013” P78-P80 with brand names such as DaySy and LumiSolarOutdoor as a method for identifying defective modules without removing modules one by one for inspection of solar cell arrays. As described above, there is a method of photographing a solar cell array with a special camera for PL (Photoluminescence) or EL (Electroluminescence) images. In addition, observations using infrared cameras are introduced in “Practical case file of solar power generation system” (by Kazuhiko Kato) P37 to P38, and JP 2013-36747 discloses a solar cell module at any position of the solar cell array. The method of judging how much the output is reduced is introduced.

しかし、上記従来技術のカメラを用いて、不良モジュールを特定する方法では、太陽電池アレイから十分に離れた高所から被写体に対して適当な角度で撮影するには、限界があり、広域な太陽光発電システムやビルの屋上などの高所の太陽電池アレイの検査に支障を来していた。  However, in the method of identifying a defective module using the above-mentioned conventional camera, there is a limit to photographing at an appropriate angle with respect to a subject from a high place sufficiently away from the solar cell array, and a wide-range solar This has hindered the inspection of photovoltaic arrays in high places such as photovoltaic systems and building rooftops.

特開２０１３−０３６７４７号公報JP 2013-036747 A ＰＨＯＴＯＮ Ｐｕｂｌｉｓｈｅｒ ＧｍｂＨ発行 Ｐｈｏｔｏｎ Ｉｎｔｅｒｎａｔｉｏｎａｌ １−２０１３PHOTOON Publisher GmbH issued by Photon International 1-2013 加藤和彦著「太陽光発電システムの不具合事例ファイル」日刊工業新聞社２０１０年Kato Kazuhiko "Solar Power Generation System Case Files" Nikkan Kogyo Shimbun 2010

本発明が解決しようとする問題点は、従来の方法では、適当な距離から適当な角度で太陽電池アレイの検査画像を撮影することが不可能という点である。  The problem to be solved by the present invention is that it is impossible to take an inspection image of the solar cell array at an appropriate angle from an appropriate distance by the conventional method.

本発明の太陽電池アレイ検査装置は、特殊カメラをラジオコントロールヘリコプターまたはラジオコントロール気球に設置することにより、適当な位置にカメラを配置することができ、検査画像の撮影を適当な距離から適当な角度で行うことが可能となる。  In the solar cell array inspection apparatus of the present invention, a special camera is installed in a radio control helicopter or a radio control balloon, so that the camera can be arranged at an appropriate position, and an inspection image can be taken at an appropriate angle from an appropriate distance. Can be performed.

本発明の太陽電池アレイ検査装置は、予備スペースの少ないビル屋上の太陽電池アレイや広域で多くの太陽電池モジュールを用いた大型の発電システムの場合であっても、十分な距離や角度からカメラ撮影が可能となり、高所や広域に設置された太陽電池アレイであっても、検査が簡単となる。また、比較的小規模な個人住宅の屋根に設置された太陽電池アレイであって、隣の家との間隔が狭く特殊カメラを地上から配置できない場合でも、本発明によれば、上空に特殊カメラを配置することにより、検査が可能となる。  The solar cell array inspection apparatus of the present invention is capable of photographing a camera from a sufficient distance and angle even in the case of a large-scale power generation system using a solar cell array on a building with little spare space or a large number of solar cell modules in a wide area. Thus, even a solar cell array installed in a high place or a wide area can be easily inspected. Further, according to the present invention, a special camera is installed in the sky even when a special camera cannot be arranged from the ground because the solar cell array is installed on the roof of a relatively small private house and the distance from the adjacent house is narrow. Inspection can be performed by arranging.

図１は本発明の太陽電池アレイ検査装置および検査方法の実施形態を示した説明図である。FIG. 1 is an explanatory view showing an embodiment of the solar cell array inspection apparatus and inspection method of the present invention. 図２は従来の太陽電池アレイ検査装置および検査方法の実施形態を示した説明図である。FIG. 2 is an explanatory view showing an embodiment of a conventional solar cell array inspection apparatus and inspection method.

本発明の太陽電池アレイ検査装置にあっては、リモートコントロール、特にラジオコントロールで地上から操作できるヘリコプターに特殊カメラを設置して、必要な位置から撮影を行う。  In the solar cell array inspection apparatus of the present invention, a special camera is installed in a helicopter that can be operated from the ground by remote control, particularly radio control, and photographing is performed from a necessary position.

図１は、本発明一実施例の装置を用いて、個人住宅４に設置された太陽電池アレイ３の検査を行う実施形態図である。ＥＬ撮影用の特殊カメラ１を設置したラジオコントロールヘリコプター２を適当は位置に静止飛行させ、個人住宅４の屋根に設置された太陽電池アレイ３のＥＬイメージを撮影する。なお、検査は、パワーコンディショナーから電気的に切り離した太陽電池アレイ３に、電圧を印加することによって得られるルミネセンスを撮影することによるのが一般的である。本発明の太陽電池アレイ検査装置と検査方法によれば、最適の位置から特殊カメラによる撮影が可能であり、太陽電池アレイを構成する数十枚の太陽電池モジュールのすべてを一回の撮影によって検査することも可能となった。  FIG. 1 is an embodiment diagram in which a solar cell array 3 installed in a private house 4 is inspected using the apparatus of one embodiment of the present invention. A radio control helicopter 2 equipped with a special camera 1 for EL photography is made to fly at an appropriate position to take an EL image of the solar cell array 3 installed on the roof of the private house 4. In general, the inspection is performed by photographing luminescence obtained by applying a voltage to the solar cell array 3 electrically separated from the power conditioner. According to the solar cell array inspection apparatus and the inspection method of the present invention, it is possible to take an image with a special camera from the optimum position, and inspect all of several tens of solar cell modules constituting the solar cell array by one image taking. It became possible to do.

従来例１Conventional Example 1

図２は、従来例の個人住宅４の屋根に設置された太陽電池アレイ３の検査装置および検査方法の実施形態図である。ＥＬ撮影用の特殊カメラ１は、カメラ保持スタンド５の先端に固定されているが、この方法では、特殊カメラ１を高い位置に保持することができず、一度に屋根の上に配置された太陽電池アレイ３を検査する事が出来ず、個人住宅のような小規模な場合でも、複数回の検査画像の撮影が必要である。また、隣接する住宅が近くにある等の場合は、カメラ保持ススタンド５を適当な場所に置くことが出来ず、検査そのものが不可能となる。さらに、高層ビルの屋上のほぼ全面に太陽電池アレイを敷き詰めたような場合、カメラ保持スタンドを配置する場所がなく、検査が不可能となり、パネルを一つ一つを検査しなければならない。  FIG. 2 is an embodiment diagram of an inspection apparatus and inspection method for a solar cell array 3 installed on the roof of a private house 4 of a conventional example. The special camera 1 for EL photography is fixed to the tip of the camera holding stand 5, but in this method, the special camera 1 cannot be held at a high position, and the sun placed on the roof at a time. Even when the battery array 3 cannot be inspected and is small like a private house, it is necessary to take a plurality of inspection images. In addition, when there is an adjacent house nearby, the camera holding stand 5 cannot be placed in an appropriate place, and the inspection itself becomes impossible. Furthermore, when a solar cell array is laid over almost the entire rooftop of a high-rise building, there is no place to place a camera holding stand, and inspection becomes impossible, and each panel must be inspected.

本発明は、ＥＬ撮影を利用した検査のみならず、ＰＬ撮影や赤外線撮影、さらにこれらの複数を利用した太陽電池アレイの検査に利用することができる。しかも、測定方法の改善がすすめば、一度に多くの太陽電池アレイを検査することも可能となり、１ＭＷ以上の発電のメガソーラー施設において、非常に有効な検査装置および検査方法となる。  The present invention can be used not only for inspection using EL imaging, but also for PL imaging and infrared imaging, and further for inspection of a solar cell array using a plurality of these. In addition, if the measurement method is improved, it is possible to inspect a large number of solar cell arrays at a time, and it becomes a very effective inspection device and inspection method in a mega solar facility with a power generation of 1 MW or more.
