Definitions

  • the invention relates to a power dissipation system for a shading device, at least with a large number of slats with photovoltaic elements for generating electricity, and a shading device with a power dissipation system.
  • busbars running through recesses in the laminations.
  • the busbars are electrically contacted via an electrically conductive ring, which forms the recess and is arranged around the busbar, as well as several wires or a type of electrically conductive brush that establishes contact between the ring and the busbar.
  • the inventors have recognized that there is an alternative possibility of dissipating the electrical energy generated in the photovoltaic elements on the movable slats of an external venetian blind or a blind to a power grid or power storage device and of avoiding the disadvantages of the prior art.
  • the invention therefore describes the possibility of dissipating current via an electrically conductive rod, strip or flat rod which runs through the cutouts in the slats, with electrically conductive sliding contacts being present in the cutouts and being electrically connected to the photovoltaic elements. Complex wiring of the individual slats is therefore no longer necessary.
  • Different photovoltaic elements can be used on the slats.
  • the different concepts for the photovoltaic slats can be divided according to the different technologies of the photovoltaic elements used.
  • First generation photovoltaic elements (wafer-based photovoltaic elements) and second generation photovoltaic elements are characterized by not exceeding the Shockley-Queisser (SQ) limit for single band section devices.
  • Third-generation photovoltaic elements have an efficiency potential above the SQ limit.
  • the SQ limit describes the maximum achievable conversion efficiency of solar energy for a specific material.
  • the frontier is the benchmark against which new photovoltaic technologies are compared.
  • a certain material has a certain band gap, which is responsible for the fact that only certain spectrums of light can be absorbed.
  • Photovoltaic elements of the third generation circumvent this fact, for example with so-called tandem photovoltaic elements, in which several materials are used in different layers in order to be able to also absorb the remaining spectrum of the light and convert it into electricity.
  • First-generation photovoltaic elements i.e. wafer-based photovoltaic elements
  • This technology is advantageous because, due to many years of research and its large market share, it has a particularly high degree of long-term testing and a very good price-performance ratio as well as a very high efficiency.
  • a major disadvantage, however, is that mass-produced photovoltaic modules using this technology are only available in sizes that cannot be applied to the slats. Therefore, slats fitted with conventional photovoltaic elements must be manufactured in such a way that the photovoltaic elements are connected and laminated to form a module on the raw slats themselves. Since individual standard photovoltaic elements are too large for the slats, these have to be cut through.
  • Photovoltaic elements of the second and third generation These photovoltaic elements have the advantage that they can be manufactured in almost any size with significantly fewer modifications of the manufacturing process, partly due to other manufacturing processes. As a result, the existing surface of the slat can be used without free spaces and thus more efficiently.
  • a decisive disadvantage is that, based on the current state of the art, photovoltaic elements of the second and third generation often cannot compete with the photovoltaic elements of the first generation in terms of their efficiency.
  • Some manufacturing processes allow the als Thin-film distinct photovoltaic cell layer to be vapour-deposited directly onto the lamellae, which thus act as a substrate.
  • the methods used during the manufacturing process include thermal evaporation, sputter deposition, laser deposition and metal-organic vapor phase epitaxy.
  • Adhesive photovoltaic elements of the second and third generation are also used here, although they are not produced on the slat itself, but on a foil and then glued to the slats. This concept has the decisive advantage that a spatial separation between the production of the slats and the production of the photovoltaic elements is possible.
  • the photovoltaic foil can be manufactured by the meter and pre-stored in the correct width and cut to size.
  • slats can also be used. Positive effects can result from the use of lamellas that are less curved in the application area of the photovoltaic elements, for example flat lamellas.
  • the photovoltaic elements only have to adapt to a less pronounced bend, which simplifies the production process and reduces the demands on the photovoltaic elements themselves.
  • the photovoltaic elements can be protected more easily from external influences. It is crucial that the encapsulation of the photovoltaic cell layer adheres sufficiently strongly and reliably to the edges of the slats so that it can develop its encapsulating effect.
  • the encapsulation can be wrapped around one or more outer edges of the slats, allowing the film to adhere to the underside of the slat as well. Since the flat lamella has no flanging on the outer edges, the film can be folded over without any problems. In the case of a lamella with a beaded edge, the film would not be able to be folded over and laminated without problems and the package height would continue to increase, since the film would reach over the bead and thus thicken the thickest part of the lamella. The film can then be attached particularly strongly to the underside by other possible methods such as gluing.
  • the inventors propose a power dissipation system for a shading device, in particular an external venetian blind or a blind, at least with a large number of slats with photovoltaic elements for generating electricity, with at least one busbar being present, which runs through recesses in the slats and connects them to one another in an electrically conductive manner in order to dissipate the current generated in the photovoltaic elements, and wherein sliding contacts are arranged in the recesses of the slats, which are electrically conductively connected to the photovoltaic elements, to the effect that the sliding contacts are designed as at least one electrically conductive contact pin and in the recesses electrically insulating insert is formed.
  • the power dissipation system serves to feed the power generated in the photovoltaic elements of the slats into a power grid or a power storage device.
  • an inverter is also advantageously provided.
  • the shading device is preferably an external venetian blind or a venetian blind, in particular a venetian blind canopy. The invention is described below using a shading device designed as an external venetian blind.
  • the slats of the external venetian blind are movably mounted in lateral guide rails by means of guide bolts attached to the short longitudinal ends.
  • the guide pins move in the guide rails.
  • the shading device in particular the external venetian blind, has at least one tension element for moving the slats.
  • the current discharge via busbars running through the slats can, of course, be combined with other ways of discharging the current generated in the photovoltaic elements, for example by means of busbars in the guide rails.
  • busbars arranged exclusively according to the invention, at least two busbars running through the laminations are formed.
  • busbars which are electrically connected to the photovoltaic elements, preferably run through each lamella.
  • more busbars to run through the laminations, in which case there is not an electrical connection to every lamina.
  • different types of series connection of the slats to increase the voltage are possible.
  • a busbar is alternately electrically connected to the slats, or the slats are insulated from the busbar.
  • the busbars run through all the laminations, even if they do not go to every lamina there is electrical contact. In an embodiment with two busbars, these are advantageously at the same potential.
  • busbar it is also possible for more than one busbar to run through a recess and for the individual busbars to be contacted differently and, for example, also to be at different potentials.
  • the busbars are advantageously connected to a power grid or power storage unit at the lower and upper ends.
  • the busbars are preferably designed to be stationary.
  • the lamellae each have recesses or openings or holes through which the busbars are guided.
  • either electrical contacts to the busbars can be present in the recesses, or the recesses can be insulated from the busbars in order to prevent electrical contact.
  • each lamella has at least two recesses, through which runs a busbar that is in contact with all lamellae for current dissipation.
  • the recesses are preferably located near the longitudinal ends of the slats.
  • sliding contacts are arranged in the recesses of the slats and are electrically conductively connected to the photovoltaic elements.
  • the sliding contacts move along the busbar when the slats are pulled up and down.
  • the electrical contact from the movable slats or sliding contacts to the stationary busbars is advantageously maintained even when the slats are tilted or rotated.
  • the busbars are advantageously contacted from at least two opposite sides. This enables better and more reliable contacting by pressing on two opposite sides.
  • sliding contacts are designed as at least one electrically conductive contact pin.
  • two contact pins are formed, which establish the electrical contact to a busbar in a recess from two opposite sides.
  • the contact pins are also advantageously spring-loaded, for example in the form of spring contact pins.
  • the contact pins have a spring mechanism in order to form a spring-loaded contacting of the busbar.
  • a preferred embodiment provides two contact pins per recess, which contact the busbar from two opposite sides, perpendicular to the longitudinal alignment of the lamella.
  • the contact pins preferably comprise an outer sleeve with a movably mounted piston arranged on the inside.
  • the contact pin has a spring which resiliently supports the piston in the sleeve. This corresponds to a conventional spring contact probe.
  • the front end of the pen-like plunger is designed as an enlarged head.
  • the piston is advantageously made of an electrically insulating material. The moveable, spring-loaded mounting of the piston enables a telescope-like change in length of the contact pin.
  • the entire contact pin is made of an elastic and bendable material, so that flexible bending of the contact pin is possible.
  • This allows the contact pin to adapt to tilting of the slats by moving up or down in the direction of the busbar is bent, as well as to a transverse movement, for example due to a temperature-related change in length of the slat by being bent sideways.
  • the contact surface to the busbar is designed to be significantly wider in order to enable optimal contacting.
  • sliding contacts are designed as at least one electrically conductive brush, for example as a copper brush.
  • an electrically conductive brush is arranged all around in the recess.
  • two individual brushes can also be arranged in the recess at least on two opposite sides.
  • an electrically insulating insert is formed in the recesses, so that the respective lamella has no contact with a busbar or just has no contact with a specific busbar of a plurality of busbars.
  • the slats can be connected to the busbars in different series circuits, for example two or three slats can be connected in series.
  • the busbars are preferably in the form of an electrically conductive rod, ribbon or cord.
  • a busbar that is flat and wide is particularly suitable, since this facilitates contacting.
  • the busbars are basically made of a material that is as conductive as possible. In a preferred embodiment, a metal or a Alloy, for example (of) copper or aluminum.
  • a busbar advantageously extends over the entire height of the shading device.
  • the current discharge system according to the invention is advantageously protected from the effects of the weather such as rain, solar radiation, etc., in order to ensure the longest possible service life with little wear.
  • One embodiment of the current dissipation system therefore provides that rubber seals and/or brush seals are inserted at least in sections into the longitudinal openings of the guide rails. These seals do not completely close the longitudinal opening, but allow the guide pins to slide up and down through the seals.
  • a brush seal also does not offer complete protection against the ingress of moisture and dust.
  • a fabric insert is arranged between the guide bolts of adjacent slats, which is stretched when the slats are in the lowered state and at least partially covers the openings of the guide rails.
  • the material used is advantageously as flexible as possible, weather-resistant and breathable as well as waterproof and UV-proof.
  • a fabric insert only protects the longitudinal opening when the slats are lowered. Depending on the material, the individual fabric areas can fray on the sides. Replacing individual slats is made more difficult by the fabric inserts attached to the slats.
  • At least two slats in each case be electrically connected to one another in series to form a set of slats, with the connection points between the two slats of a set of slats being parallel to one another via a busbar in each case are electrically coupled.

  • the shading device in particular an external venetian blind, provides that the curtain comprises at least a first set of slats and a second set of slats, the sets of slats being tilted differently about the respective longitudinal axes of the slats.
  • This type of curtain is also generally referred to as a two-part curtain.
