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 invention relates to a self-supporting, air-cooled photovoltaic installation module.
  • Der Stand der Technik wird durch PV-Module gekennzeichnet, deren handelsübliche Grösse auf maximal einen Quadratmeter bemessen ist. The prior art is characterized by PV modules whose commercial size is sized to a maximum of one square meter. Im Falle des Baues grosser PV-Solarstromfarmen entsteht damit ein beträchtlicher Montageaufwand für die einzelnen Module auf einer geeigneten Unterkonstruktion. In the case of the construction of large PV solar power farms with a considerable assembly effort for the individual modules on a suitable support structure is created.
  • Hinzutritt, dass die herkömmlichen PV-Module im Betrieb bei intensiver Sonneneinstrahlung im Inneren sehr warm werden und damit an Leistung verlieren. Supervention that conventional PV modules are very warm during operation in strong sunlight inside and lose power. Die einfache Kühlung durch Abstrahlung und einfache Luftumströmung auf der Vorder- und Rückseite zeigt deutliche Nachteile gegenüber einer verbesserten Luftführung. The simple cooling by radiation and easy air flow around to the front and back shows significant disadvantages compared to 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. The existing objects of the cast, self-supporting structure and the improved air cooling can be achieved in that the PV cells carrying solar glass, or solar glass panels of approximately 4000 by 1000 mm in a self-supporting sandwich construction of approximately 4,000 by 1,000 will mmm applied. Die Sandwichkonstruktion aus Aluminium besteht aus einem Oberblech, einem Trapezblech und einem Unterblech, die fest mit einander verbunden werden. The sandwich construction made of aluminum consists of an upper plate, a trapezoidal plate and a lower plate which are rigidly connected to each other. Das in der Mitte befindliche Trapezblech ist in der Querrichtung trapeziert, so dass in der Längsrichtung eine grosse Steifigkeit gegeben ist. The trapezoidal sheet metal located in the center is trapeziert in the transverse direction, so that in the longitudinal direction a large stiffness is given. Die mit dem Trapezblech verbundenen Ober- und Unterbleche gewährleisten eine hohe Quersteifigkeit. Associated with the trapezoidal sheet metal top and bottom plates provide high lateral stiffness.
  • Das Sandwichmodul ist damit geeignet, grosse statische und dynamische Lasten zu tragen, wie sie aus dem Eigengewicht und Schnee sowie zum Beispiel Windlasten entstehen. The sandwich module is thus capable of carrying large static and dynamic loads as they arise from the dead weight and snow as well as wind loads. 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. The sandwich module comprises on the underside below two fastening hooks and on the underside of the top two fixing lugs, with which the top of the top of the large collector bottom in the substructure, is consisting suspended from a lower elevated purlin like a movable bearing and with the upper tabs at the , elevated purlin is attached as a fixed bearing. 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 distinction between a floating bearing and fixed bearing enabling a substructure, which is hardly subjected to thermal stresses, and in particular thermal expansions of the PV modules.
  • 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. The sandwich module has, in addition to the high stiffness in the longitudinal and transverse direction without that the PV cells must accommodate significant forces bearing glass, the bottom-up running in the longitudinal direction of the trapezoidal channels. Diese Kanäle überwinden durch ihre Länge von beispielsweise 4000 mm je nach Neigungswinkel eine Höhendifferenz von zB 3000 mm und enthalten ein großes, sich erwärmendes Luftvolumen, so dass ein konvektiver Naturzug entsteht, der die PV-Module auf der Rückseite kühlt. These channels overcome by their length, for example 4000 mm, depending on the inclination angle of a height difference of, for example 3000 mm, and contain a large, to be heated volume of air, so that a convective natural draft which cools the PV modules on the back.
  • 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 as the electric power of the PV modules greatly decreases over the increasing internal temperature by 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.
  • Die Zeichnung II stellt den Schnitt durch das selbsttragende Sandwich mit den Kanälen dar. The drawing II represents the section through the self-supporting sandwich with the channels.
  • Die Zeichnung III stellt den Schnitt durch die obere und untere Befestigung auf den Pfetten sowie die Ansicht des Befestigungselementes mit horizontaler Achse dar. The drawing III represents the section through the upper and lower attachment to the purlins as well as the view of the fastener having a horizontal axis.
