Description

  1. A) Üblicherweise werden Photovoltaikanlagen entweder „auf Dach“ oder „in Dach“ montiert:
    1. 1. Bei der Aufdachmontage werden die Dachziegel zuerst entfernt, Halterungen auf die hölzerne Unterkonstruktion des Daches fixiert, anschließend die Dachziegel wieder über die Halterungen gelegt und die Photovoltaikpaneelen mittels Montageprofilen an den Halterungen befestigt. Bei dieser Montageart ergeben sich folgende Probleme:
      • • Das Wiederauflegen der Dachziegel auf die (auf die hölzerne Unterkonstruktion montierten) Halterungen verhindert einen Formschluss der Dachziegel, es entstehen zwangsweise Öffnungen, die zu einer Undichtigkeit des Daches führen.
      • • Bei der anschließenden Montage der Montageprofile und der Photovoltaikpaneelen muss das Dach vom Monteur betreten werden, Brüche von wieder aufgelegten Dachziegel können die Folge sein.
      • • Bei nachträglicher Montage einer Photovoltaikanlage auf ein bestehendes Dach müssen bereits durch das Alter defekte Dachziegel ausgetauscht werden, ggf. das Dach komplett neu eingedeckt werden.
    2. 2. Bei der Indachmontage verzichtet man auf die Eindeckung des Daches mittels Dachziegel, die Photovoltaikpaneelen werden mittels eines Schienensystems direkt auf die hölzerne Unterkonstruktion fixiert: Hierbei umschließen die Schienen jede einzelne Photovoltaikpaneele. Bei dieser Montageart ergeben sich folgende Probleme:
      • • Eine absolute Wasserdichtigkeit des Schienensystems ist schwer zu realisieren: Temperaturschwankungen auf dem Dach und Materialermüdung durch UV-Strahlung führen unweigerlich zur Undichtigkeit der Konstruktion.
      • • Den Photovoltaikpaneelen fehlt durch die direkte Montage auf dem Dach Hinterlüftung, d.h. es kommt zum Hitzestau hinter den Paneelen, der Wirkungsgrad der Paneelen wird herabgesetzt.
    A) Photovoltaic systems are usually installed either "on the roof" or "in the roof":
    1. 1. When installing on the roof, the roof tiles are first removed, brackets are fixed to the wooden substructure of the roof, then the roof tiles are placed back over the brackets and the photovoltaic panels are attached to the brackets using mounting profiles. The following problems arise with this type of installation:
      • • Placing the roof tiles back on the brackets (installed on the wooden substructure) prevents the roof tiles from fitting tightly, openings are forced to occur, which lead to leaks in the roof.
      • • During the subsequent assembly of the assembly profiles and the photovoltaic panels, the roof must be walked on by the fitter, which can result in the roof tiles being replaced breaking.
      • • If a photovoltaic system is retrofitted to an existing roof, roof tiles that are defective due to age must be replaced or the roof completely re-tiled.
    2. 2. In the case of in-roof installation, the roof is not covered with roof tiles, the photovoltaic panels are fixed directly to the wooden substructure using a rail system: the rails enclose each individual photovoltaic panel. The following problems arise with this type of installation:
      • • Absolute watertightness of the rail system is difficult to achieve: temperature fluctuations on the roof and material fatigue due to UV radiation inevitably lead to leaks in the construction.
      • • Due to the fact that the photovoltaic panels are mounted directly on the roof, there is no rear ventilation, ie heat builds up behind the panels and the efficiency of the panels is reduced.
  2. B) Durch eine Kombination aus „auf Dach“ und „in Dach“ Montage mittels einer Dachziegelfreier, selbstabdichtender, modularer Dacheindeckung mit integriertem Montageprofil zur Aufnahme von Photovoltaikmodulen werden die oben genannten Probleme gelöst:
    • • Nach Entfernung der Dchziegel wird eine aus Metall gefertigte Platte direkt auf den Holzkonstruktion des Daches montiert. Es werden keine Dachziegel mehr auf die Platte gelegt, es ist keine Erneuerung der Dachziegel nötig.
    • • Die modularen Platten besitzen an den Rändern ein vorgeformtes überlappendes Profil, welches die Dichtigkeit der Konstruktion ermöglicht.
    • • Die Platten sind bereits mit Montageprofilen versehen, auf die die Photovoltaikpaneelen fixiert werden. Damit ist eine Hinterlüftung der Paneelen gegeben, es findet kein Hitzestau statt.
    • • Beim Montieren der Paneelen betritt der Monteur die Metall-Platten. Da keine Dachziegel in diesem Bereich vorhanden sind, können keine Dachziegel brechen.
    B) The problems mentioned above are solved by a combination of “on the roof” and “in the roof” installation using a tile-free, self-sealing, modular roof covering with an integrated installation profile for accommodating photovoltaic modules:
    • • After removing the roof tiles, a metal plate is mounted directly on the wooden structure of the roof. No more roof tiles are placed on the plate, no renewal of the roof tiles is necessary.
    • • The modular panels have a preformed overlapping profile on the edges, which allows for the tightness of the construction.
    • • The panels are already provided with mounting profiles to which the photovoltaic panels are fixed. This means that the panels are ventilated from behind, and there is no heat build-up.
    • • When assembling the panels, the assembler steps onto the metal plates. Since there are no roof tiles in this area, no roof tiles can break.

Somit stellt die Kombination aus „auf Dach“ und „in Dach“ Montage ein Optimum dar. Mittels einer dachziegelfreien, selbstabdichtenden, modularen Dacheindeckung mit integriertem Montageprofil zur Aufnahme von Photovoltaikmodulen kann dies erreicht werden.Thus, the combination of "on the roof" and "in the roof" installation represents an optimum. This can be achieved by means of a tile-free, self-sealing, modular roof covering with an integrated mounting profile for accommodating photovoltaic modules.
