Description

Solar active surfaces are so far difficult to integrate into the architecture. This is true especially for the integration into houses with plaster, stone, concrete or other mineral facades, but also z. For example Wooden, clay or half-timbered houses. Especially the big one Mass of existing buildings in cities (Old buildings / inventory) have for the most part on this construction. Both from design, as well as technical, in particular for building physical reasons Glass facades or glass facade elements are usually not applicable here. Special The retrofitting of the facades of existing ones presents difficulties Houses with solar active elements.

From the DE 44 14 785 A1 a shutter or awning with overhead hinge is known. To increase the performance of solar-technical facade systems is provided to provide the outside with a mirror surface and above the folding device to arrange a solar cell module or a collector. By unfolding it appropriately, diffused solar radiation should be directed towards the surface of the solar cell module or collector.

The DE 299 17 020 U1 discloses a side hinged Dämmladen having a reflector surface on the inboard side. In the unfolded state this Dämmladen is able to direct solar radiation on the windows. In the closed state are characterized by the insulating properties of the store according to the DE 299 17 020 U1 Transmission heat losses reduced.

In WO 98/21434 A1 is a Drehladen for window or door openings disclosed movable by a arranged in the Drehladen electric motor is.

From the DE 195 31 040 C2 is a sliding shutter with a grid or plate-shaped protective element for a window or door element known which is parallel to a wall opening horizontally displaceable. The plate-shaped protective element is concealed in the open position in a mounted adjacent to the door or window opening receiving space. Furthermore, the protective element can be locked by a bolt in the protective and open position. A displacement of the protective element is carried out by an electric drive or manually.

The US 4,294,038 describes a shutter provided with a window and the gap therebetween for utilizing absorbed heat energy. The sun energy radiating onto the shutter causes a warming of the gap between the window and the shutter. To utilize this energy in the form of heat is the aim of the described invention.

In the US 4,309,981 discloses an optional either up or down folding shutter. Depending on whether the shutter is opened upwards, this serves to reflect the sun in the space behind it. If the shutter according to the US 4,309,981 open at the bottom, it serves to shield the window from the sun.

The DE 84 03 263 U1 discloses a swing-out venetian blind, which is also suitable for use with solar energy converters (solar cells), the slats then being provided with solar energy converters. It is according to the DE 84 03 263 U1 provided that the slats are within a freely pivotable in the horizontal direction, rigid frame and the slats can take any selectable pivot position even in each pivotal position of the frame. The lamellae are provided lockable against rotation about their longitudinal axis and thus form a secured tank in the closed position.

Of the in claim 1 protection invention is based on the problem a shading element for Window or door openings to use solar energy, which is largely free Window or door accessibility an increased energy yield guaranteed and at the same time architecturally appealing integrated.

The inventive problem is achieved by a shading element for window or door openings, wherein the outside directed surface the shading element is covered with solar cells, wherein the Shading element in its closed as well as open State adjustable to the incidence of light and aligned relative to this is, characterized in that the shading element laterally from the window or door openings away substantially parallel to the window or door opening is displaceable, that the shading element also has a partial covering of the window or door opening guaranteed and that the solar cells over a power take-off contact grid are connected together.

In developments of the shading element according to the invention solar cells are provided, which are formed monocrystalline and consist of hexagonal units. Furthermore, it is provided that the solar cells consist of hexagonal, whole and / or half units. According to the invention it is further provided that in a Verschat Processing element, the current collection grid is wave-shaped.

In a development has an inventive shading element two hingedly connected to the shading element, adjacent metal rods on, by means of which the shading element laterally from the Window or door opening away, essentially parallel, displaceable.

The solar active shutter solves this problem by
can be mounted on the façade with just a few fixing points
does not interfere with the building physical structure of the wall structure and so before z. As plaster, clay, timbered, wood or natural stone facades can be mounted
an ideal place that is both architecturally and aesthetically pleasing
the oblique adjustment of the solar active surface allows and so on the one hand, an increased energy yield allows, as well as on the other hand at the same time free window ventilation
through the free installation in front of the façade, optimum ventilation and heat dissipation is possible, which greatly increases in particular the current yield / efficiency of most solar modules commonly used today
can serve as a sun protection element, but if necessary also disappears completely sideways
ideal easy to retrofit.

For the photovoltaic Solar modules have hexagonal tailored monocrystalline Solar cells have proven to be very efficient for solar active shutters, because they are the module area from the area occupation very well.

1 - 3

For example ( 4 ) are photovoltaic shutters with hexagonal solar cells for the renovation of old Berlin tenements shown. The window to facade ratio of these buildings is ideally exploited by a solar active shutter. In addition, it is by the lockability from the inside also an ideal burglary protection and replaces the function of blinds or curtains.
