Abstract

The module has a solar glass plate (1) attached with photovoltaic cells on a rigid sub-structure in longitudinal and transverse direction. The rigid sub-structure has an air duct running in the longitudinal direction, and is implemented as a sandwich unit of upper and lower plates with an intermediately placed trapezoidal plate (3). The plate is applied on the sandwich unit, and the substructure has two fastening units with horizontal axis to connect in a base purlin and two plates to fix on a ridge purlin.

Description

Die Erfindung betrifft ein selbsttragendes, luftgekühltes Photovoltaik-Montagemodul.The The invention relates to a self-supporting, air-cooled photovoltaic mounting module.

Der Stand der Technik wird durch PV-Module gekennzeichnet, deren handelsübliche Grösse auf maximal einen Quadratmeter bemessen ist. Im Falle des Baues grosser PV-Solarstromfarmen entsteht damit ein beträchtlicher Montageaufwand für die einzelnen Module auf einer geeigneten Unterkonstruktion.Of the The prior art is characterized by PV modules whose commercial size to maximum one square meter is measured. In the case of the construction of large PV solar power farms thus creates a considerable Assembly costs for the individual modules on a suitable substructure.

Hinzutritt, dass die herkömmlichen PV-Module im Betrieb bei intensiver Sonneneinstrahlung im Inneren sehr warm werden und damit an Leistung verlieren. Die einfache Kühlung durch Abstrahlung und einfache Luftumströmung auf der Vorder- und Rückseite zeigt deutliche Nachteile gegenüber einer verbesserten Luftführung.Supervention, that the conventional PV modules in operation in intense sunlight inside get very warm and lose power. The simple cooling through Radiation and simple air circulation on the front and back shows significant disadvantages an improved air flow.

Die bestehenden Aufgaben der gossen, selbsttragenden Struktur und der besseren Luftkühlung werden dadurch gelöst, dass die die PV-Zellen tragende Solarglassscheibe oder Solarglasscheiben von ca. 4000 mal 1000 mm auf eine selbsttragende Sandwichkonstruktion von ca. 4.000 mal 1.000 mmm aufgebracht wird. Die Sandwichkonstruktion aus Aluminium besteht aus einem Oberblech, einem Trapezblech und einem Unterblech, die fest mit einander verbunden werden. Das in der Mitte befindliche Trapezblech ist in der Querrichtung trapeziert, so dass in der Längsrichtung eine grosse Steifigkeit gegeben ist. Die mit dem Trapezblech verbundenen Ober- und Unterbleche gewährleisten eine hohe Quersteifigkeit.The existing tasks of the cast, self-supporting structure and the better air cooling are solved by that the PV cells carrying solar glass or solar glass panes of 4000 x 1000 mm on a self-supporting sandwich construction of about 4,000 times 1,000 mm is applied. The sandwich construction made of aluminum consists of a top sheet, a trapezoidal sheet metal and a sub-sheet, which are firmly connected with each other. This in the center trapezoidal sheet is trapezoidally trapezoidal, so that in the longitudinal direction a great rigidity is given. The connected to the trapezoidal sheet Ensure upper and lower sheets a high transverse rigidity.

Das Sandwichmodul ist damit geeignet, grosse statische und dynamische Lasten zu tragen, wie sie aus dem Eigengewicht und Schnee sowie zum Beispiel Windlasten entstehen. Das Sandwichmodul weist auf der Unterseite unten zwei Befestigungshaken und auf der Unterseite oben zwei Befestigungslaschen auf, mit denen von oben der Grosskollektor unten in die Unterkonstruktion, bestehend aus einer unteren, aufgeständerten Pfette wie bei einem Loslager eingehängt wird und mit den oberen Laschen an der oberen, aufgeständerten Pfette wie bei einem Festlager befestigt wird. Die Unterscheidung zwischen Loslager und Festlager ermöglich eine Unterkonstruktion, die kaum den thermischen Belastungen und insbesondere den thermischen Dehnungen der PV-Module ausgesetzt wird. The Sandwich module is thus suitable, large static and dynamic To carry loads, as from their own weight and snow as well as to Example wind loads arise. The sandwich module points at the bottom two fastening hooks at the bottom and two fastening straps at the bottom underneath on, with which from above the large collector down into the substructure, consisting of a lower, uplifted purlin like a Suspended bearing is and with the upper tabs on the upper, elevated Purlin is attached as a fixed bearing. The distinction between floating bearing and fixed bearing enables a substructure, hardly the thermal loads and in particular the thermal strains the PV modules is exposed.

Das Sandwichmodul weist neben der hohen Steifigkeit in Längs- und Querrichtung ohne dass das, die PV-Zellen tragende Glas nennenswerte Kräfte aufnehmen muss, die von unten nach oben in Längsrichtung verlaufenden trapezförmigen Kanäle auf. Diese Kanäle überwinden durch ihre Länge von beispielsweise 4000 mm je nach Neigungswinkel eine Höhendifferenz von z.B. 3000 mm und enthalten ein großes, sich erwärmendes Luftvolumen, so dass ein konvektiver Naturzug entsteht, der die PV-Module auf der Rückseite kühlt.The Sandwich module has in addition to the high rigidity in longitudinal and Transverse direction without the glass carrying the PV cells absorbing appreciable forces must, from the bottom up in the longitudinal direction running trapezoidal channels. Overcome these channels by their length for example, 4000 mm, depending on the angle of inclination, a height difference from e.g. 3000 mm and contain a large, warming Air volume, so that a convective natural train is created, which the PV modules on the back cools.

Dieser Effekt ist ausserordentlich erwünscht, da die elektrische Leistung der PV-Module über der zunehmenden inneren Temperatur durch die eingestrahlte Sonnenenergie erheblich abnimmt.This Effect is extremely desirable since the electrical power of the PV modules over the increasing internal Temperature considerably decreases due to the incident solar energy.

Die erfindungsgemäße Vorrichtung ist in drei Zeichnungen dargestellt.The inventive device is shown in three drawings.

Die Zeichnung I stellt die Ansicht des selbsttragenden Grosskollektors dar.The Drawing I represents the view of the self-supporting large collector represents.

Die Zeichnung II stellt den Schnitt durch das selbsttragende Sandwich mit den Kanälen dar.The Drawing II shows the section through the self-supporting sandwich with the channels represents.
