Description
Die Erfindung betrifft ein Solarmodul und ein Herstellverfahren für ein Solarmodul.The invention relates to a solar module and a manufacturing method for a solar module.
Solarmodule, auch Photovoltaikmodule oder im Folgenden kurz „Module” genannt, dienen zur Umwandlung von Sonnenlicht in elektrische Energie. Herkömmliche Solarmodule weisen hierbei folgenden Schichtaufbau auf, beginnend mit der der Sonne zugewandten Seite: eine Deckschicht aus Glas, eine Schmelzfolie, Solarzellen, eine weitere Schmelzfolie, eine Rückseitenfolie.Solar modules, also called photovoltaic modules or "modules" for short, are used to convert sunlight into electrical energy. Conventional solar modules in this case have the following layer structure, starting with the side facing the sun: a cover layer of glass, a melt film, solar cells, another melt film, a backsheet.
Nachteil an diesen Modulen ist, dass diese zurzeit nur bis ca. 85–90°C temperaturbeständig sind. Viele Module fallen nach wenigen Jahren aus, bzw. die Leistung verringert sich durch Degradation. Darüber hinaus nimmt die Leistung des Modules im „Sonnenbetrieb” ab, da die Module erhitzen und die Solarzellen weniger Leistung erzeugen. Dieser Effekt kann beispielsweise durch eine Kühlung der Module begrenzt werden. Die momentan in den Modulen eingesetzten Folien sind jedoch stark wärmeisolierend. Die Wirksamkeit der Kühlung wird dadurch stark begrenzt.Disadvantage of these modules is that they are currently only up to about 85-90 ° C temperature resistant. Many modules fail after a few years, or the performance is reduced by degradation. In addition, the performance of the module decreases in "solar operation" as the modules heat up and the solar cells produce less power. This effect can be limited for example by cooling the modules. However, the films currently used in the modules are very heat-insulating. The effectiveness of cooling is thereby severely limited.
Der Erfindung liegt die Aufgabe zugrunde, ein langzeitstabiles und Insbesondere temperaturstabiles Solarmodul anzubieten. Ferner ist es Aufgabe der Erfindung ein Herstellverfahren für ein derartiges Solarmodul anzugeben.The invention has for its object to offer a long-term stable and particularly temperature-stable solar module. It is another object of the invention to provide a manufacturing method for such a solar module.
Diese Aufgabe wird für das Solarmodul durch die Merkmale des Patentanspruchs 1 und für das Herstellverfahren durch die Merkmale des Patentanspruchs 6 gelöst. Vorteilhafte Ausführungsformen des Solarmoduls bzw. des Herstellverfahrens sind in den Unteransprüchen beschrieben.This object is achieved for the solar module by the features of
Im Weiteren wird die während des Betriebs der Sonne zugewandte Seite des Solarmoduls auch als „Vorderseite” bzw. „vorderseitig” und die der Sonne abgewandte Seite des Solarmoduls als „Rückseite” bzw. „rückseitig” bezeichnet.In addition, the side of the solar module facing the sun during operation is also referred to as "front side" or "front side" and the side of the solar module facing away from the sun is referred to as "rear side" or "rear side".
Erfindungsgemäß besitzt das Solarmodul eine Deckschicht aus Glas, eine an der Deckschicht anschließende transparente Schmelzfolie, an der Schmelzfolie anschließende Solarzellen und eine Vergussmasse aus Polyurethan (Abk.: PU), in der die Solarzellen eingebettet sind. Durch das Einbetten der Solarzellen in die Vergussmasse aus Polyurethan kann auf die herkömmlich rückseitig von den Solarzellen angeordnete Schmelzfolie und die Rückseitenfolie verzichtet werden. Dadurch wird die Temperaturempfindlichkeit des Solarmoduls verringert. Die maximale Einsatztemperatur steigt entsprechend.According to the invention, the solar module has a cover layer made of glass, a transparent melt film adjoining the cover layer, solar cells adjoining the melt film and a potting compound of polyurethane (abbr .: PU), in which the solar cells are embedded. By embedding the solar cells in the potting compound of polyurethane can be dispensed with the conventional arranged on the back of the solar cell melt film and the backsheet. This reduces the temperature sensitivity of the solar module. The maximum operating temperature increases accordingly.
Darüberhinaus erhöht die Vergussmasse die Stabilität des Solarmoduls. Dadurch kann die Dicke der Deckschicht entsprechend reduziert werden. Eine Reduktion der Deckschicht wiederum erhöht die solare Ausbeute des Moduls. Insbesondere kann die herkömmliche Dicke der Deckschicht auf etwa 50% reduziert werden. Damit erhöht sich die Ausbeute um ca. 5% gegenüber herkömmlichen Modulen. Insbesondere kann die herkömmliche Glasstärke von 4–5 mm auf etwa 2 mm verringert werden.In addition, the potting compound increases the stability of the solar module. As a result, the thickness of the cover layer can be reduced accordingly. A reduction of the cover layer in turn increases the solar yield of the module. In particular, the conventional thickness of the cover layer can be reduced to about 50%. This increases the yield by about 5% compared to conventional modules. In particular, the conventional glass thickness can be reduced from 4-5 mm to about 2 mm.
In einer bevorzugten Ausführungsform ist rückseitig an der Vergussmasse eine Metallfolie, insbesondere eine Stahlfolie, angeordnet. Diese Metallfolie bildet eine gut wärmeleitende Beschichtung der Vergussmasse. Damit kann die Kühlung des Solarmoduls verbessert werden. Auf diese Weise kann die Temperaturbeständigkeit des Solarmoduls auf über 100°C werden. Folglich ist ein fangjähriger, störungsfreier Betrieb auch in heißen Gegenden (Italien, Afrika usw.) möglich.In a preferred embodiment, a metal foil, in particular a steel foil, is arranged on the rear side of the potting compound. This metal foil forms a good heat-conducting coating of the potting compound. Thus, the cooling of the solar module can be improved. In this way, the temperature resistance of the solar module can be over 100 ° C. Consequently, a catchy, trouble-free operation in hot areas (Italy, Africa, etc.) is possible.
Die Kühlung kann des Weiteren durch Anlegen einer Metallplatte, ggf. mit Kühlkörpern, an die Metallfolie oder einer Integration von passiven und/oder aktiven Kühlelementen in die Metallfolie verbessert werden. Durch die Kühlung wird das Modul um durchschnittlich 20°C niedriger betrieben, d. h. es werden auch ca. 10% mehr kWh erzeugt. Beispiel:
180 Watt Modul bei 1000 Sonnenstunden erzeugt = 180 kWh;
180 Watt Modul, mit Kühlung erzeugt bei 1.000 Sonnenstunden = 198 kWh.The cooling can be further improved by applying a metal plate, possibly with heat sinks, to the metal foil or an integration of passive and / or active cooling elements in the metal foil. By cooling the module is operated on average 20 ° C lower, ie it will also generate about 10% more kWh. Example:
180 watts module generated at 1000 hours of sunshine = 180 kWh;
180 watt module, with cooling generated at 1,000 hours of sunshine = 198 kWh.
In einer weiteren bevorzugten Ausführungsform sind ein seitlicher Abschlussrahmen des Solarmoduls und/oder Anschlusselemente der Solarzellen mit der Vergussmasse vergossen. Ein derartiger Abschlussrahmen bildet einen bevorzugten seitlichen Abschluss Solarmoduls, ohne herkömmliche Probleme mit Klebeband und Aluminiumrahmen. Dadurch kann eine erhöhte Betriebssicherheit und ein langlebigeres Modul erzielt werden. Ferner können ein Eingießen einer Rückseiten-Box und/oder die Integration der Dioden direkt in die Vergussmasse erfolgen. Dadurch wird die Degradation verringert und die Lebensdauer des Moduls erhöht.In a further preferred embodiment, a lateral end frame of the solar module and / or connection elements of the solar cells are encapsulated with the potting compound. Such a termination frame forms a preferred solar module side termination without conventional tape and aluminum frame problems. As a result, increased reliability and a more durable module can be achieved. Furthermore, pouring a backside box and / or the integration of the diodes can be done directly in the potting compound. This reduces the degradation and increases the life of the module.
Das erfindungsgemäße Herstellverfahren für ein Solarmodul umfasst die folgenden Verfahrensschritte:
- (a) Erzeugen eines Stapels aus der Deckschicht, der Schmelzfolie und den Solarzellen;
- (b) Einbetten der Solarzellen in die Vergussmasse.
- (a) generating a stack from the Cover layer, the melt film and the solar cells;
- (b) embedding the solar cells in the potting compound.
In einer bevorzugten Ausführungsform erfolgt vor dem Verfahrensschritt (b) ein Laminieren, insbesondere bei einer Laminiertemperatur von 170°C bis 190°C, bevorzugt mit 180°C, des aus der Deckschicht, der Schmelzfolie und den Solarzellen bestehenden Stapels.In a preferred embodiment, prior to process step (b), lamination takes place, in particular at a lamination temperature of 170 ° C. to 190 ° C., preferably 180 ° C., of the stack consisting of the cover layer, the melt film and the solar cells.
In einer weiteren bevorzugten Ausführungsform wird die Vergussmasse zumindest teilweise auf die Metallfolie aufgebracht und anschließend, insbesondere nach einer Antrockenphase der Vergussmasse auf der Metallfolie, erfolgt durch ein Anpressen oder Andrücken der mit Vergussmasse beschichteten Metallfolie an die Solarzellen ein Einbetten der Solarzellen in die Vergussmasse.In a further preferred embodiment, the potting compound is at least partially applied to the metal foil and then, in particular after a dry phase of the potting compound on the metal foil, is carried out by pressing or pressing the potting compound-coated metal foil to the solar cells embedding the solar cells in the potting compound.
In vorteilhafter Weise werden die Komponenten des Solarmoduls nach dem Verfahrensschritt (b) durch ein Laminierverfahren, insbesondere ein sogenanntes Inverslaminierverfahren, miteinander verbunden.Advantageously, the components of the solar module after the process step (b) by a lamination process, in particular a so-called Inverslaminierverfahren, interconnected.
