【発明の詳細な説明】 本発明は光電池モジュールに関し、更に詳細には、光
電池モジュールの枠と一体的に形成される接続箱に関す
る。The present invention relates to a photovoltaic module, and more particularly to a junction box formed integrally with a frame of the photovoltaic module.
光電池モジュールは太陽光により発電を行なう装置で
ある。光モジュールの一例として太陽電池パネルがあ
る。普通、光電池モジュールは枠に取付けた複数の太陽
電池により太陽の光エネルギーを直接電気に変換する。
太陽電池はシステムの必要条件および太陽電池パネルお
よび太陽電池自身の設計条件に基ずいて種々の構成に接
続可能である。The photovoltaic module is a device that generates power using sunlight. A solar cell panel is an example of an optical module. Normally, photovoltaic modules convert solar light energy directly into electricity by a plurality of solar cells mounted in a frame.
Solar cells can be connected in various configurations based on the requirements of the system and the design conditions of the solar panel and the solar cell itself.
光電池モジュールは普通、各々を電気系統に接続する
ための１つあるいは２以上の接続箱を有する。これらの
接続箱は光電池モジュールの裏面に配置されてその裏面
の一部を覆う。この構成の一例としてアーコ・ソーラ・
インク（Arco Solar,Inc.）製造のモデルナンバーM55の
ソーラパネルがある。Photovoltaic modules typically have one or more junction boxes for connecting each to an electrical system. These connection boxes are arranged on the back surface of the photovoltaic module and cover a part of the back surface. An example of this configuration is Arco Solar
There is a solar panel with model number M55 manufactured by Ink (Arco Solar, Inc.).
この構成では、接続箱が太陽電池パネルの裏面に永久
に固着され、太陽電池パネルの電気的健全性を維持する
ために周囲の環境から封止される。これは時間および費
用のかかるやり方である。例えば、上板用と下板用の２

めに下板に孔を穿孔する必要がある。接続箱をパネルの
裏面に設ける際のもう１つの問題点はモジュールの組立
て時およびこれを取り扱う際壊れ易いことである。接続

接続箱をつかむと便利がよい。しかしながら、このため
接続箱をパネルの裏面に保持する接着性封止材が破壊さ
れてパネルの電気的および環境封止的健全性が破壊され
やすくなる。In this configuration, the junction box is permanently fixed to the back surface of the solar cell panel and is sealed from the surrounding environment to maintain the electrical integrity of the solar cell panel. This is a time consuming and expensive procedure. For example, 2 for upper plate and 2 for lower plate
In a module using two glass plates, it is necessary to make holes in the lower plate for electrical connection. Another problem with providing the junction box on the back of the panel is that it is fragile when assembling and handling the module. Since the junction box is located on the back of the panel, it is convenient to grasp the junction box when moving the panel. However, for this reason, the adhesive sealing material that holds the connection box on the back surface of the panel is broken, and the electrical and environmental soundness of the panel is easily broken.
接続箱を光電池モジュールの裏面に取付ける場合のも
う１つの問題は接続箱により裏面の一部が覆われること
である。これは両面型太陽電池を用いた太陽電池パネル
にとっては特に重要である。両面型太陽電池は、その前

直流の電圧および電流を発生する電池である。両面型太
陽電池を光電池モジュールに用いる場合、太陽電池の裏
面が覆われないようにすることが肝要である。Another problem when attaching the junction box to the back surface of the photovoltaic module is that the junction box partially covers the back surface. This is particularly important for solar cell panels using double-sided solar cells. A double-sided solar cell is excited by light impinging on both its front and back, i.e.,
It is a battery that generates DC voltage and current. When a double-sided solar cell is used for a photovoltaic module, it is important that the back surface of the solar cell is not covered.
本発明の目的は、構造的、電気的および環境封止的健
全性が向上しモジュール裏面の遮蔽を最少限に抑えるか
零にした光電池モジュールおよび接続箱を提供すること
にある。It is an object of the present invention to provide a photovoltaic module and a junction box with improved structural, electrical and environmental integrity and with minimal or no shielding on the back of the module.

は任意に選ぶことが出来るが、矩形であることが好まし
い。同様に、接続箱と一体的に形成する枠部材は任意の
ものでよいが、短い方の枠部材のひとつであることが好
ましい。The present invention includes a solar cell stack for power generation, a plurality of frame members that support the solar cell stack, and a connection box that connects the solar cell stack to an electric system, wherein the connection box includes at least one frame member. The present invention relates to a photovoltaic module formed integrally. The shape and size of the entire frame formed by the frame members can be arbitrarily selected, but are preferably rectangular. Similarly, the frame member integrally formed with the connection box may be any one, but is preferably one of the shorter frame members.
本発明はモジュール裏面の遮蔽を最少限に抑えるか、
好ましくは零にする必要のある両面型太陽電池を用いた
光電池モジュールに特に有用である。接続箱を枠と一体
的に形成することにより、光電池モジュールの裏面が覆
われることがなく、従って何れの太陽電池も遮蔽される
ことがない。この結果光電池モジュールの効率が増加す
る。The present invention minimizes shielding on the back of the module,
It is particularly useful for a photovoltaic module using a double-sided solar cell, which preferably needs to be zero. By forming the connection box integrally with the frame, the back surface of the photovoltaic module is not covered, and thus no solar cells are shielded. As a result, the efficiency of the photovoltaic module increases.
本発明は光電池モジュールの構造的、電気的および環
境封止的健全性を向上させる効果があるため、両面型太
陽電池を有する光電池モジュールだけに限定されるわけ
ではない。接続箱と枠を一体化したことによる本発明の
もう１つの利点は、接続箱を２つでなく１つに減らすた
め光電池モジュールの全コストが減少することである。The present invention is not limited to a photovoltaic module having a double-sided solar cell because it has the effect of improving the structural, electrical, and environmental soundness of the photovoltaic module. Another advantage of the present invention by integrating the junction box and frame is that the total cost of the photovoltaic module is reduced by reducing the junction box to one instead of two.
接続箱を光電池モジュールの裏面に取付けない構造の
ためモジュールの構造的、電気的および環境封止的健全
性が向上する。接続箱をモジュールの裏面に取付けない
ので、光電池モジュールを取り扱う人が環境封止部を不
用意に破壊してモジュールの電気的健全性を損なう可能
性が非常に低い。The structure in which the connection box is not attached to the back surface of the photovoltaic module improves the structural, electrical, and environmental soundness of the module. Since the junction box is not attached to the back of the module, it is very unlikely that a person handling the photovoltaic module will inadvertently destroy the environmental seal and impair the electrical integrity of the module.
本発明の枠と一体化した接続箱は光電池モジュールの
並列／直列接続およびそれらの電気系統への接続を容易

接続は太陽電池積層体の端縁部で行なうことが出来る。
また本発明の枠と一体化した接続箱は全てのモジュール
につき均一な標準型枠部品を用いることによって光電池
モジュールの全コストの減少を可能にする。The junction box integrated with the frame of the present invention facilitates parallel / series connection of photovoltaic modules and their connection to the electrical system. In addition, there is no need to form an opening by piercing the lower plate of the solar cell stack. Instead, the electrical connection to the solar cells can be made at the edges of the solar cell stack.
Also, the junction box integrated with the frame of the present invention allows for a reduction in the overall cost of the photovoltaic module by using uniform standard formwork components for all modules.
以下、添付図面を参照して本発明を好ましい実施例に

いが、これは必要条件でない。FIG. 1 is a view of the photovoltaic module 1 as viewed from the front side. No connection box is arranged on the back surface of the photovoltaic module 1. Instead, the connection box 4 is preferably formed integrally with one frame member 5 at the top or bottom of the photovoltaic module 1. By forming the connection box 4 integrally with the shorter frame member, the amount of material used for the connection box can be reduced. However, the connection box 4 may be connected with any frame member.
It can be integrally formed as one unit. The junction box 4 preferably extends over the entire width of the photovoltaic module 1, but this is not a requirement.

好ましい。With the double-sided photovoltaic module of the present invention, the surrounding area is 4%.
Efficiency is reduced by 4% accordingly, but the net efficiency is increased because the junction box does not shield the back of the module. In existing photovoltaic modules, the backs of several solar cells are shielded to attach two junction boxes and their associated bus connection means to the back of the photovoltaic module. Typically, the total area of these components is about 150 cm 2 or about 3.5% of the module area. Shielding these areas reduces power output and efficiency. However, this reduction in efficiency is greater than the area to be shielded. Conservative predictions can be reduced to 1 / 1.5. In the example where 3.5% of the area is shielded, this results in a 5.3% reduction in efficiency, which is greater than the 4% loss due to the increased surrounding area of the photovoltaic module of the present invention. This increase in efficiency by not shielding the backside of the module is particularly important since in many instances the area surrounded by the photovoltaic module is not as important as its power output. As a result, modules that generate 5.3% or more of power with the same number of solar cells are preferred over smaller modules with lower power output.
