Definitions

  • the present invention relates to a photovoltaic roof tile for obtaining electrical energy from solar energy, wherein the photovoltaic roof tile has substantially the shape of a conventional roof tile.
  • Photovoltaic is a widely used technique for using solar radiation.
  • the solar radiation hits a photovoltaic module with solar cells. These convert the energy of the sunlight into electrically usable energy.
  • the conversion of solar energy into electrically usable energy is well known and we will not explain in more detail.
  • roof areas for the attachment of solar collectors is widespread.
  • Commercially available solar collectors are usually additionally applied to already finished roofs. It often fasteners must be mounted through the roof on the roof support structure, the attachment must be storm proof and preferably also protected against corrosion.
  • When piercing the conventional roof skin inevitably sealing and subsequent leakage problems caused.
  • there is an increase in the roof load which often entails a necessary reinforcement in the roof truss.
  • solar panels adversely affect the visual appearance of the roof.
  • photovoltaic roof tiles are known which are used instead of the commonly used roof tiles, roof tiles or roof tiles. Photovoltaic roof tiles include the top side, ie facing the sun, photovoltaic modules or solar cells for receiving and converting the solar energy.
  • the installation of roof tiles described therein is complicated and difficult, especially because additional components are required and changes to the Wearing structure are necessary.
  • the object of the present invention is to provide a photovoltaic roof tile whose manufacture, installation and maintenance is as simple and inexpensive. It is essential that the assembly process differs as little as possible from a roof covering with conventional roof tiles.
  • a photovoltaic roof pan according to the invention accordingly has a photovoltaic module arranged on the top side on a base pan, which is connected to a first power line and a second power line.
  • the base pan is used to attach the photovoltaic roof tile on a roof.
  • the photovoltaic roof tile is preferably sandwiched, wherein the photovoltaic module between the base pan and a transparent cover member is arranged.
  • the base pan can be made according to the invention metal, and in particular be prepared by deep drawing.
  • a circulating between the base pan and the photovoltaic module frame member serves for a fixing of the individual elements together, on the other hand, the tightness of the photovoltaic roof tile is increased against water penetration.
  • the shape of the photovoltaic roof tile according to the invention substantially corresponds to the shape of a conventional roof tile, so that the appearance of a roof or a house is hardly changed by using the photovoltaic roof tile.
  • the term roof tile is to be understood as a synonym for roofing elements such as roof tiles, roof tiles or shingles and should not limit the invention to roof tiles.
  • the first power line has at its free end a first connecting element and the second power line at its free end a second connecting element, which are electrically conductively connected to one another.
  • both connection elements may be arranged within outer dimensions of the photovoltaic roof tile.
  • at least one connecting element can be pulled out due to the variable-length line, so that it projects beyond the outer dimensions of the photovoltaic roof tile.
  • outer dimensions or external dimensions refers to the outer dimensions of the photovoltaic roof tile in planar or horizontal extent, which are determined in a conventional rectangular photovoltaic roof tile through the two longitudinal sides and the two transverse sides.
  • horizontal and vertical refer to a resting on a horizontal plane photovoltaic roof tile, so that their main extension thus extends in a horizontal plane.
  • the photovoltaic roof tile according to the invention in its ground state has the same dimensions as a commercial roof tile without photovoltaic module.
  • the second connecting element can be pulled out beyond the outer dimensions of the photovoltaic roof pan and connected to a first connecting element of an adjacent photovoltaic roof pan.
  • the two connected photovoltaic roof tiles can be moved towards each other, whereby the second power line is shortened again, until the two photovoltaic roof tiles are arranged one above the other in such a way that the two connections tion elements below the overhead photovoltaic roof pan so no longer visible, are arranged.
  • the first power line or the second power line or even both power lines can be made variable in length; in a particularly advantageous embodiment, according to the invention, only the second power line is variable in length.
  • the invention is therefore explained for this embodiment variant, which, however, represents only one of the various possibilities.
  • the second connecting element connected to the second power line is preferably guided in a longitudinal groove extending in the extension direction in the base pan.
  • the first power line and the first connecting element are arranged stationary within the outer dimensions of the photovoltaic roof tile.
  • variable-length first power line makes installation on the roof much easier, since distance deviations between adjacent photovoltaic roof tiles and different overlaps of the photovoltaic roof tiles during the roofing can be compensated quickly and easily.
  • the different coverage of the pans arises due to different lath spacing, which in turn arise because of the integer number of tiles, when different roof lengths must be realized (from the eaves to the ridge).
  • variable-length first power line is to be understood such that it changes in length with respect to the extension direction of the second connecting element.
  • the second power line for this reason may be a so-called trumpet tube, in which two pipe sections of different diameters can move into each other.
  • the pipe sections can themselves be made electrically conductive, but it is also possible the arrangement of a cable within the pipe sections, which then preferably have an insulating effect.
  • a second power line can be used whose absolute length remains the same, however, due to the change in the geometric arrangement, an increase in length in the extension direction
  • the function of the invention is crucial, namely that the second power line allows withdrawal of the second connecting element.
  • the electrical connection of the connecting elements is effected by contact surfaces which are respectively arranged on the connecting element. These contact each other in the assembled state of the connecting elements, so that the electric current can be passed.
  • contact surfaces can also be provided elsewhere in the photovoltaic roof pan, ie independently of the connecting elements.
  • the two connecting elements are designed as latching or latching connection.
  • the first connecting element may have a receiving opening, in which the second connecting element is held insertable and releasably positively.
  • the positive connection can be effected by an undercut in the receiving opening, on which a retaining edge of the second connecting element comes to rest.
  • elastic locking means may be provided which engage in corresponding holding areas.
  • the second connecting element may have openings or recesses into which engage elastic and / or spring-loaded pins of the first connecting element.
  • the pins are initially displaced by the second connecting element until they can move back into the corresponding recesses or openings.
  • the two connecting elements are firmly connected to each other in the locked state, wherein the connection is effected in particular by at least one, preferably two spring-loaded pins.
  • the latching opening and the free end of the pin are dimensioned so that the pin is only partially and not completely inserted into the opening.
  • the pin can be conically shaped at its free end, for example. This ensures that the connection in the vertical direction, ie transverse to the introduction "- - ⁇ - is locked, on the other hand, the force acting in the longitudinal direction of the pin spring force presses the two connecting elements against each other, which ensures a secure and durable connection.
  • other snap-in connections can be used, which cause a sufficiently reliable connection of the two connecting elements.
  • connection of the connecting elements can be achieved again by pressing the pins back against the spring force and pulling the second connecting element out of the first connecting element.
  • a suitable tool can be used, which disengages the pin and the latching opening.
  • the second connection element is guided.
  • the guide can be effected, for example, by a longitudinal groove in the base pan into which a holding region of the second connecting element protrudes and is held. This ensures that the second connecting element can move exclusively along the longitudinal groove and in particular can not twist.
  • the receiving opening within the first connecting element is T-shaped and open at the top.
  • the second connecting element is also T-shaped and inserted from above into the receiving opening.
  • the T-shape automatically creates a blockage in a substantially horizontal pulling direction. So that the connection can not be released in the vertical direction, spring-loaded pins which are arranged in the first connection element engage in openings of the second connection element, which are preferably arranged in the two short regions of the T-shape formed transversely to the longitudinal extension of the second power line.
  • the receptacle and the latching element can at least partially be formed from electrically conductive material and form the contact surfaces for conducting the electrical current.
  • the pins themselves and an edge of the receptacle which contact the pins in the assembled state can form the contact surfaces.
  • the photovoltaic roof tiles according to the invention can be laid quickly and easily on a roof rack construction. They can be transported with inserted second connecting element as normal commercial roof tiles on the roof and processed there. For this purpose, it is only necessary to take off the second connecting element from the photovoltaic roof tile and to connect via the latching connection with an adjacent first connecting element.
  • the so-called eaves of the roof adjacent photovoltaic roof tiles preferably have connection lines instead of the first power lines.
  • the connection lines can also be made variable in length and can be connected with their free ends to a main power line leading to a consumer or energy storage.
  • Particularly advantageous is a laying of the main power line within a arranged at the house downpipe. This is used to drain rainwater, but can also accommodate main power line inside. These may be separated in a particularly preferred embodiment by a partition of a rainwater-conducting portion of the downpipe. The drop tube is therefore divided into two chambers for this purpose.
  • a pilot current can also be forwarded via the connecting elements. This is necessary in particular for so-called CAN buses.
  • the photovoltaic roof tile according to the invention is particularly suitable for use with a likewise new and advantageous wind suction protection.
  • Windsovers are already mandatory regionally when installing roof tiles. It's about covering the Dr - ' J (Wind suction) to prevent. This is typically accomplished by attaching a wire or clip to the tile anchoring it to the roof batten.
  • the anchoring is relatively time-consuming, it sometimes takes more time depending on the circumstances on site than the roof of the roof itself.
  • the wind suction protection according to the invention reduces these problems.
  • a snap claw is triggered when placing the roof tile on the roof tile, works with spring force behind the tile and hooks behind it.
  • a return mechanism is advantageously provided with a pull rod with towing eye on the underside of the roof tile in the front area. If the roof pan is raised slightly at the front, it is possible to reach into the drawbar eye with a hook and pull the snap claw back into its rest position by pulling it. This locking position is the delivery condition and is when you cover the roof, so if the roof tile is placed in the right position on the batten, changed. Replacing a traditional roof tile has always been relatively difficult (even without additional wind suction protection).
  • Another improvement or alternative of the invention is to actuate a further drawbar with towing eye at the front end of the roof tile to release the connection between the tiles by operating an ejector (to eject a pater from a material).
  • the three drawbar eyes are all located below the roof tile at the bottom. The drawbar eyes are vertical and would “spring down" from the underside of the roof tile as soon as it is lifted in.
  • an eyelet is slightly offset from the center of the roof tile (center of the front) and triggers the connection.
  • the drawbar eye for the snapping claw of the wind suction device is positioned This position is advantageous because the classic wind suction protection is always provided on the left side of the roof tile
  • a few centimeters to the right of the center preferably also 3 cm to the right of the center
  • there is preferably a pull eye for the draw key which serves to raise the roof tile Roof ladle lift conceivable, w
