本発明は、太陽電池モジュールの構造に関するものであ

従来例の構成とその問題点
従来、太陽電池の用途は、僻地用独立電源が主体であっ

1 oow以下のものが大半を占めていた。Conventional configurations and their problems Conventionally, solar cells have been mainly used as independent power sources for remote areas. Therefore, the output of solar cells is mainly in the tens of watts, and in most cases when used, one or several solar modules are connected in series or in series and parallel, and the total system output is less than 1 oow. It was occupied.
しかし、昨今太陽電池のコスト低下とともに、応用範囲
が大幅に広がり、大出力の太陽電池システムが建設され

電位差が生じるだめ。In large power generation systems, due to the problem of resistance loss,
High-voltage, low-current power generation systems are commonly used, and if the solar cell installation stand and solar cell frame are grounded, a high potential difference will occur between the solar cell frame and the solar cell element.
太陽電池パネルとフレーム間は、高い絶縁耐圧が要求さ

いられて来た。On the other hand, solar cell elements have a high risk of being damaged by impact, etc., so it has been common practice to encapsulate them in transparent resin. , materials whose withstanding voltage characteristics do not change, such as silicone resins and polyvinyl butyral resins, have been used.

When it comes into contact with /, it has the property of being oxidized and deteriorated, and its adhesive strength with other members tends to decrease due to water vapor and the like.

層で裏面シートとして用いた例もあるが、外気を完全に
遮断できないために、充填樹脂の酸化劣化。For these reasons, currently, a white tempered glass plate is installed on the light-receiving surface side in order to completely block the resin from the outside air, and an aluminum film or a triplet of fluorine resin, aluminum, and fluororesin is installed on the non-light-receiving surface side. A layered laminated film is used, and the surrounding area of the solar cell panel is completely sealed off from the outside air by using a sealant. In addition to the above-mentioned materials, there have been examples of using a single layer of plastic film as the back sheet for the non-light-receiving surface side, but since it cannot completely block out the outside air, the filling resin deteriorates due to oxidation.

ている。Resin peeling occurs due to water vapor intrusion. When an aluminum film with a sheet thickness of 26 μm or more is used, it has no pinholes, so it can completely block the outside air and the filled resin, and it can also completely prevent water vapor from entering from the outside. For these reasons, currently, the back member installed on the non-light-receiving side of a solar cell module is mainly a single-layer aluminum film or a three-layer laminate film of fluororesin, aluminum, and fluororesin. .

面部材間に高電位差が生じるため、現在では、上記のス
パークによる透明樹脂の焦げる事故が多発している。However, when a conductive metal material such as aluminum is used for the solar cell back member, the insulation resistance between the back member and the frame tends to be extremely low unless an insulating member is provided between the solar cell panel and the frame. In general, transparent resins such as polyvinyl butyral have a high dielectric constant, so when a high DC voltage is applied between the solar cell element and the back member of the solar cell, a capacitor is formed using the transparent filled resin as a dielectric.
When the back side of the solar cell element is negatively charged and the back side member is charged with positive charges, and the insulation resistance of the transparent filling resin decreases, there is a risk that sparks will occur between the two members and the transparent resin will burn. Therefore, if the insulation resistance between the back member and the frame is small, in a high power generation system where there is a large potential difference between the solar cell element and the frame, a high potential difference will occur between the solar cell element and the back member. There are many accidents in which transparent resin is scorched due to the above-mentioned sparks.
