Description
Die Erfindung betrifft eine Anordnung zur Erzeugung von Strom nach dem Oberbegriff des Anspruchs 1.The The invention relates to an arrangement for generating electricity after Preamble of claim 1.
Eine
solche Anordnung ist aus der
Aufgabe der Erfindung ist es, die Nachteile nach dem Stand der Technik zu beseitigen. Es soll insbesondere eine möglichst einfach und kostengünstig herstellbare Vorrichtung angegeben werden, mit der über einen langen Zeitraum hinweg Strom mit einem hohen Wirkungsgrad erzeugt werden kann.task The invention is to the disadvantages of the prior art remove. In particular, it should be as simple as possible and inexpensively producible device can be specified with the electricity over a long period of time with a high Efficiency can be generated.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Merkmalen der Ansprüche 2 bis 9.These The object is solved by the features of claim 1. Expedient embodiments of the invention result from the features of claims 2 to 9.
Nach Maßgabe der Erfindung wird vorgeschlagen, dass zwischen den fotovoltaischen Elementen und dem Flachdach ein Reflektor vorgesehen ist, dessen zu den fotovoltaischen Elementen gewandte Reflektorfläche bezüglich der Horizontalen schräg geneigt ist. – Infolge der vorgeschlagenen schrägen Neigung des Reflektors kann dieser durch zwischen den stabförmigen fotovoltaischen Elementen hindurchdringendes Regenwasser gereinigt werden. Durch diese überraschend einfache Maßnahme gelingt es, den Wirkungsgrad der Anordnung über lange Zeit hinweg auf einem hohen Niveau zu halten.To According to the invention, it is proposed that between the photovoltaic elements and the flat roof, a reflector provided is, which turned to the photovoltaic elements reflector surface is inclined at an angle to the horizontal. - As a result the proposed oblique inclination of the reflector can this through between the rod-shaped photovoltaic Elements penetrating rainwater to be cleaned. By this surprisingly simple measure succeeds the efficiency of the arrangement over a long time on to maintain a high level.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist der Reflektor aus Metall hergestellt. Metallische Oberflächen weisen eine hohe Reflektivität auf. Es ist dazu nicht unbedingt erforderlich, diese zu bearbeiten. Nach einer besonders vorteilhaften Ausgestaltung ist die Reflektorfläche aus spiegeleloxiertem Aluminium oder Edelstahl mit IIId-Oberflächenqualität hergestellt. Damit kann eine besonders hohe Reflektivität erreicht werden. Vorteilhaft ist es weiter, hoch reflektierende metallische Oberflächen mit einer transparenten Schicht zu versehen. Damit kann eine Korrosion vermieden werden. Eine solche Schicht kann aus einem Polymer, einem keramischen Polymer oder dgl. hergestellt sein.To An advantageous embodiment of the invention is the reflector made of metal. Have metallic surfaces a high reflectivity. It is not necessarily required to edit this. After a particularly advantageous Design is the reflector surface of mirror-anodized Aluminum or stainless steel with IIId surface quality produced. This can be a particularly high reflectivity be achieved. It is advantageous further, highly reflective metallic surfaces with a transparent layer to provide. Thus, corrosion can be avoided. Such a layer can be made of a polymer, a ceramic polymer or the like be.
Nach einer weiteren Ausgestaltung der Erfindung können die Reflektorflächen Rinnen aufweisen, welche korrespondierend zu den darüber befindlichen fotovoltaischen Elementen ausgebildet sind. Wegen der rinnenartigen Ausgestaltung der Reflektorfläche kann das darauf einfallende Licht auf einen der Sonne abgewandten Abschnitt der stabförmigen fotovoltaischen Elemente konzentriert werden. Falls die fotovoltaischen Ele mente horizontal angeordnet sind, ist es zweckmäßig, dass sich die Rinnen in Richtung zum Flachdach hin konisch erweitern. Damit kann die Schrägstellung des Reflektors kompensiert und dennoch eine effektive Reflektion von Licht auf die stabförmigen fotovoltaischen Elemente erreicht werden.To In a further embodiment of the invention, the reflector surfaces Have grooves which correspond to the above located photovoltaic elements are formed. Because of the groove-like design of the reflector surface can incident light on a section facing away from the sun the rod-shaped photovoltaic elements concentrated become. If the photovoltaic ele ments are arranged horizontally, It is appropriate that the gutters in the direction expand conically towards the flat roof. This can be the inclination of the reflector compensates for yet effective reflection of light on the rod-shaped photovoltaic elements be achieved.
Nach einer weiteren Ausgestaltung kann es auch sein, dass die Reflektorfläche pult- oder satteldachartig ausgestaltet ist. Die Herstellung eines Reflektors mit einer solchen Reflektorfläche ist besonders einfach. Ein entsprechender Reflektor kann kostengünstig bereitgestellt werden.To In a further embodiment, it may also be that the reflector surface console or saddle roof-like configured. The production of a Reflector with such a reflector surface is special easy. A corresponding reflector can be inexpensive to be provided.
Des Weiteren hat es sich als zweckmäßig erwiesen, dass der Reflektor Bestandteil des Fotovoltaikmoduls ist. In diesem Fall ist die Montage der vorgeschlagenen Anordnung besonders einfach. Dabei kann der Reflektor mit sich vom Fotovoltaikmodul erstreckenden Stützelementen verbunden sein.Of Furthermore, it has proven to be expedient that the reflector is part of the photovoltaic module. In this Case, the assembly of the proposed arrangement is particularly simple. In this case, the reflector with extending from the photovoltaic module Be connected support elements.
Die Neigung der Reflektorfläche beträgt zweckmäßigerweise 5 bis 10°.The Inclination of the reflector surface is expediently 5 to 10 °.
Nach einer weiteren Ausgestaltung der Erfindung ist eine von den fotovoltaischen Elementen abgewandte Rückseite des Reflektors mit einer geräuschdämmenden Schicht versehen. Eine solche Schicht kann beispielsweise durch eine aufgeklebte Matte gebildet sein, welche aus einem geräuschdämmenden Material besteht. Es kann auch sein, dass der Reflektor in Form eines Hohlkörpers ausgebildet ist, welcher mit einem geräuschdämmenden Material ausgefüllt ist. Es kann sich dabei gleichzeitig um ein wärmedämmendes Material, wie Polymerschaum, Polystyrol, Mineralfaserwolle oder dgl., handeln.To Another embodiment of the invention is one of the photovoltaic Elements facing away from the rear of the reflector with a sound absorbing layer provided. Such a layer can be formed for example by a glued mat, which consists of a sound absorbing material. It may also be that the reflector in the form of a hollow body is formed, which with a sound-absorbing Material is filled. It can work at the same time a heat-insulating material, such as polymer foam, polystyrene, Mineral fiber wool or the like, act.
