Folded solar membrane

from Wikipedia, the free encyclopedia

As Folded solar membrane a is from solar panels , and (partially) transparent safety glass existing facade element designates which for optimized energy generation by means of solar cells and for shading of the underlying glass architecture is used.

The folded solar membrane was developed in 2011 by Nabo Gaß for the high-bay warehouse of the Ernsting's family .

Development and use

The aim was to optimize the use of commercially available photovoltaic modules in vertical facade surfaces. In order to counteract the loss of efficiency of approx. 30% that inevitably occurs with a vertical installation of a PV system , the modules were mounted at the optimal angle in front of the facade, which on the one hand guarantees the greatest possible energy efficiency, on the other hand, due to the opacity of the solar panels, a very good one Shading of the glass high shelf behind it is made possible. The areas between the photovoltaic modules were closed with crash glass for aesthetic reasons. This creates the impression of a transparent facade structured in horizontal folds, which encases the glass high shelf in the south / east and south / west.

The natural use of solar modules horizontally or on sloping ceilings experiences a sensible application that is comparable in efficiency thanks to the folded solar membrane .

The use of the folded solar membrane and its continuation on the roof as an elevated PV system leads in the case of the glass high-bay warehouse of the Ernsting's family to an energy yield that fully covers the energy requirement over the year. In addition, the folded solar membrane makes a significant contribution to ensuring that operation without heating and cooling can be guaranteed even at extreme temperatures.

In 2012, the facade received the architecture award from pbb Stiftung Deutsche Pfandbriefbank .
