  • a connection of solar modules with noise protection components and the associated general advantages have been known for a long time.
  • a basic problem with this connection is that the surface of solar modules is generally sound-reflecting and therefore diametrically opposes the desired properties of a noise protection component.

  • EP 1 788 155 A2 shows an ecological noise protection wall in a lightweight construction with vertical supports anchored in a foundation and wedge-shaped sound absorption elements, which have a sound absorbing sound absorption material and a roof for protection against weather influences.
  • the sound absorbing material consists of natural and renewable raw materials made of straw, straws or fibers of vegetable origin.
  • WO 2017/091077 Al describes a sun protection module that can be used as part of a noise barrier along a motorway.
  • the sun protection module has shading plates which can be arranged on a scaffold between two transparent walls and can contain photovoltaic cells in order to convert the radiation energy of the sun rays striking the shading plates into electrical energy.
  • a sun tracking system is used to move the shading panels so that they are aligned with the sun.
  • the disadvantage here is the complex construction, which results from the traceability of the individual shading plates necessary.
  • the invention provides a device of the type mentioned, the slats elongated frame struts bil the.
  • the slats are both a support structure for the solar modules and frame struts. This allows the frame to be structurally reinforced using the slats. Especially seen before support structures and elaborate constructions for connecting these support structures to the frame can thus be saved and the cross section of the frame can be dimensioned smaller. This saves costs and reduces the view area of the device in the direction of view normal to a frame level, so that when the device according to the invention is attached of the wall, the surface of the wall behind the device, which is directly accessible for incoming sound, is reduced as little as possible in order to keep the effective sound absorption surface of the wall as large as possible.
  • the view area corresponds to the area of a projection of the device into the frame plane.
  • the device is particularly suitable for use on an at least partially transparent noise barrier.
  • the device When viewed parallel to the sound (e.g. for occupants of a noise-producing vehicle), the device is only slightly restricted by the noise protection wall and the advantages of a view of the surrounding landscape are largely retained.
  • the device can be attached to existing or newly erected walls without additional post construction and foundation being necessary and with only a slight additional load on the wall.
  • vertical loads can be derived from existing or new uprights of the existing or new walls via the supports by means of an attachment with the aid of the two support projections, each with one support.
  • simple and inexpensive manufacture of the device and simple assembly of the pre-fabricated elements can be made possible.
  • the solar modules can already be electrically connected during the prefabrication, so that the device can be installed quickly with comparatively few common electrical connections.
  • the device can be easily replaced in the event of repairs and damage.
  • the slats can be arranged essentially in parallel. This allows the effective surface of the solar modules, which are arranged on the lamellae, to be maximized. That is, the largest possible area of the photovoltaic cells of the solar modules can be used to strike the light rays.
  • the face of the device can direction can be maximized from an expected average angle of incidence of sun rays, so that adjacent slats directly adjoin each other in this view. Due to the parallel arrangement, a substantially continuous usable area can be achieved. At the same time, shading of the solar modules by adjacent slats is minimized.
  • the slats can be arranged substantially parallel to a horizontal edge of the device when in use.
  • the slats can be arranged substantially parallel to a connecting line between the two wearing projections. This has the advantage that when several devices are lined up in series, the impression of continuous slats is created. For a moving observer with respect to the devices, the arrangement of the slats with respect to distant observation points also remains stable, so that the parallel horizontal arrangement is particularly suitable for use on an at least partially transparent wall.
  • At least three slats with solar modules can be arranged on the front of the frame at regular intervals.
  • the slats can be designed the same without impairing the usable area, whereby the manufacturing process and costs of the slats can be simplified or reduced.
  • the arrangement contributes at regular intervals to minimize the visual impairment when used on a transparent noise barrier, because a uniform arrangement is less conspicuous than an uneven arrangement and is less perceptible to the human eye or can be hidden better.
  • the solar modules can be arranged on the slats at an oblique angle with respect to a frame plane. In this way, the solar modules can be arranged at an angle at which the efficiency of the solar modules is greatest.
  • the changing angle of light over the course of the day results in an arrangement of the solar modules which, calculated over the entire year, results in maximum absorption of solar radiation leads.
  • the vertical distance between solar modules arranged on two adjacent parallel slats is advantageously selected such that the upper edge of the solar module, which is arranged on the lower slat, the imaginary shadow line starting from the lower edge of the solar module, that is arranged on the upper lamella, and does not exceed normal to the surface of the solar module.
  • the lamellae can have at least one bracing angled with respect to the solar module.
  • the lamellae have, for example, a two-legged (for example V or L-shaped) or multi-legged profile, where the solar module is arranged on one of the two flat parts of the profile and the other (optionally also flat) part which forms the bracing, Prevents torsion and / or bending of the slats. Due to the stiffening, the slats can be dimensioned with a smaller thickness. This serves both the material and thus cost savings and the reduction of the total weight of the device. A small total weight increases the compatibility of the device with existing walls, in particular noise barriers, because this reduces the requirements for their additional load that can be absorbed.
  • the slats are coated at least in sections with a sound-absorbing surface and / or covered with sound-absorbing material.
  • the sound absorption capacity of the device according to the invention is increased in that sound arriving directly from a noise source or on a solar module or on a (e.g. partially transparent) noise barrier can be absorbed.
  • the sound reflecting effect of solar modules can be compensated for at least in part and the overall sound absorption coefficient of the wall can be improved.

  • a lamella device can generally also be used advantageously without solar modules, for example in order to improve the sound absorption behavior of an otherwise predominantly sound-reflecting noise barrier (for example a transparent noise barrier).
  • the invention relates to a noise barrier with at least one such slat device.
  • standing tabs for connection to a carrier can be provided on the support projections to the side of the supports, the tabs preferably being arranged parallel to the frame plane. A horizontal slipping of the supports can be avoided by connecting the brackets to a carrier.
  • the tabs can form stops, for example, which are arranged at a defined distance outside the frame, and specify a corresponding distance between the frame and a wall carrying the device.
  • At least one spacer extends outwards from the rear of the frame.
  • wind loads of the device according to the invention can be introduced into the existing or new noise protection wall, as a result of which the device can be kept at a distance from a load-bearing wall and can be made more filigree, so that material and costs can subsequently be saved and weight can be reduced.
  • the frame can be formed from shaped tubes and / or angles, in particular from metal. Since the frame can be manufactured inexpensively from a material with high strength. In addition, a comparatively high structural integrity of the frame is achieved with less material and weight. Furthermore, the frame can have at least one diagonal train.
