Abstract

Nachführbares Trackersystem für Solarmodule dadurch gekennzeichnet, dass der Gelenkkopf (1) im Schwerpunkt der Trackerfläche liegt.Trackable tracker system for solar modules, characterized in that the condyle (1) lies in the center of gravity of the tracker surface.

Description

Es gibt verschiedene nachführbare Trägersysteme (Tracker) für Solarmodule. Diese bestehen üblicherweise aus einer Turmeinheit, einem Gelenkkopf und der Trackerfläche, die die unterschiedlichen Solarmodule trägt und gemäß Sonnenstand ausrichtet. Üblicherweise liegt der Gelenkkopf hinter der geschlossenen Trackerfläche, was zu unterschiedlichen Problemen führt. Der Gelenkkopf liegt durch die übliche Anordnung nicht im Schwerpunkt der Gesamtkonstruktion, was zu einem hohen Energie- und Konstruktionsaufwand für die Nachführung des Trackers führt. Des Weiteren führt die übliche Anordnung des Gelenkkopfes zu einer Limitierung des Bewegungsumfangs der Trackerfläche, da eine durchgehende oder teilweise geteilte Trackerfläche keine 360 Grad-Drehung der Trackerfläche erlaubt.There are various tracking systems (trackers) for solar modules. These usually consist of a tower unit, a condyle and the tracker surface, which carries the different solar modules and aligns according to the position of the sun. Usually, the condyle is behind the closed tracker surface, which leads to different problems. The condyle is not due to the usual arrangement in the center of gravity of the overall design, resulting in a high energy and design effort for the tracking of the tracker. Furthermore, the usual arrangement of the condyle leads to a limitation of the range of motion of the tracker surface, since a continuous or partially divided tracker surface does not allow a 360 degree rotation of the tracker surface.

Die Erfindung ist gekennzeichnet durch den in der Gesamtkonstruktion zentral angeordnetem Gelenkkopf (A(1)). Somit entsteht eine statisch und funktional optimierte Gesamtsituation, die Solarmodule unterschiedlichster Größe nachführen kann. Dies reduziert den Energie- und Bewegungsaufwand für die Nachführung.The invention is characterized by the centrally arranged in the overall design condyle ( A ( 1 )). This creates a statically and functionally optimized overall situation that can track solar modules of all sizes. This reduces the energy and movement costs for the tracking.

Die Erfindung ist dadurch gekennzeichnet, dass der Gelenkkopf im Schwerpunkt der Trackerfläche liegt (A(1)) und durch zwei seitlich angeordnete Kranzelemente (B(3)) der zentrale Verteilungspunkt von seitlich ausstrahlenden Tragelementen ist (B(2)). Diese Tragelemente halten die Solarmodule. Die Tragelemente verlaufen vornehmlich fächerförmig (B(2)) über die gesamte Fläche. Die Fächerform ergibt sich aus den vornehmlich gleichen Winkeln der einzelnen Tragelemente zueinander.The invention is characterized in that the condyle is in the center of gravity of the tracker surface ( A ( 1 )) and by two laterally arranged ring elements ( B ( 3 )) is the central distribution point of laterally radiating support elements ( B ( 2 )). These support elements hold the solar modules. The support elements are mainly fan-shaped ( B ( 2 )) over the entire surface. The fan shape results from the predominantly same angles of the individual support elements to each other.

Des Weiteren erlaubt die Erfindung eine neue Art des Schutzes der Solarmodule bei Sturm, Hagel, Regen oder Schnee, da die Erfindung durch seinen gesteigerten Bewegungsumfang der Trackerfläche eine dem Erdboden zugewandte Schutzposition (C(4)) der Solarmodule ermöglicht. Des Weiteren bietet die Erfindung durch die Schutzposition die Möglichkeit, die nächtliche Taubildung auf den Solarmodulen zu unterbinden (C(5)).Furthermore, the invention allows a new way of protecting the solar modules in storm, hail, rain or snow, since the invention by its increased range of motion of Trackerfläche a ground-facing protective position ( C ( 4 )) of the solar modules allows. Furthermore, the invention offers through the protective position the possibility of preventing the nighttime dew formation on the solar modules ( C ( 5 )).

Die Erfindung ist dadurch gekennzeichnet, dass neben dem Gelenkkopf (A(1)) jeweils ein nach hinten zurückversetzter Kranz (D(6)) die Tragelemente aufnimmt. Durch diese Rückversetzung der Tragelemente entsteht eine statisch funktionale Ebene, deren Einzelelemente alle die gleiche Bauhöhe aufweisen. Durch diese durchgängige Bauhöhe entsteht die Möglichkeit, prinzipiell baugleiche Elemente einzusetzen.The invention is characterized in that, in addition to the condyle ( A ( 1 )) in each case a set back to the rear wreath ( D ( 6 )) receives the support elements. This return movement of the support elements creates a statically functional plane whose individual elements all have the same height. Through this continuous height creates the opportunity to use basically identical elements.

Die Erfindung ist dadurch gekennzeichnet, dass die wesentlichen Tragelemente (B(2)) durch x-förmige Elemente (E(7)) versteift werden. Diese x-förmige Aussteifung führt zu einer Gewichtsersparung der Tragelemente bei gleichbleibender Steifigkeit.The invention is characterized in that the essential supporting elements ( B ( 2 )) by x-shaped elements ( e ( 7 )). This x-shaped stiffener leads to a weight saving of the support elements with the same rigidity.

A Tracker mit Gelenkkopf in zentraler Position A Tracker with condyle in central position

B Tracker von hinten, seitlich fächerförmig angeordnete Tragelemente B Tracker from the rear, laterally fan-shaped support elements

C Tracker in Schutzposition C Tracker in protective position

D Tracker mit nach hinten versetztem Kranzelement D Tracker with rearwardly offset rim element

Eine realistische Anwendungsmöglichkeit der Erfindung ist in der Solarindustrie zu sehen. Die Erfindung führt durch Ihre innovative Schwerpunktgestaltung und Tragwerkskonstruktion zu einem geringeren Energie- und Kostenaufwand bezüglich Herstellung, Betrieb und Wartung des Trackers. Des Weiteren erlaubt der neugewonnene Bewegungsumfang der Trackerfläche eine Schutzposition zur Unterstützung der Langlebigkeit des Produktes. Die Gewichtsreduktion beinhaltet eine Materialersparnis des Gesamtsystems.A realistic application of the invention is seen in the solar industry. With its innovative center of gravity design and structural design, the invention reduces energy and costs associated with the manufacture, operation and maintenance of the tracker. Furthermore, the newly gained range of movement of the tracker surface allows a protection position to support the longevity of the product. The weight reduction involves a material saving of the whole system.
