Definitions

  • the invention relates to a fastening device, in particular for high-performance photovoltaic modules, consisting of a plurality of profile strips, which are provided for the positive reception of the modules.
  • photovoltaic modules have made their use interesting in our latitudes, taking into account the amortization costs.
  • photovoltaic systems are preferably attached to inclined roofs in order to use the available solar radiation and generate inexpensive electricity.
  • the plug-in connections have also proven to be unusable, since permanent contact is not guaranteed due to the effects of the weather, or the cables that are led out in the fastening area on the individual modules lead to cable breaks. In such a case, a single cable interruption can shut down an entire generator or at least reduce the efficiency due to a reduced cross section with an increased cable resistance.
  • the irradiation usually corresponds almost exactly to the theoretical yield of a solar power system per kilowatt system output if the output of a solar module is determined in the laboratory under standard test conditions. These are, for example, 1,000 watts of solar radiation per square meter with an efficiency of 100 percent that cannot be achieved in practice. A solar module with a size of one square meter would therefore produce an output of exactly 1 kilowatt.
  • the solar modules currently on the market achieve a realistic efficiency of around 10%, so that around ten times the area is required per kilowatt system output.
  • the effects mentioned above must be taken into account here: in strong sunlight, the temperature of the solar modules is up to 80 degrees, significantly higher than 25 degrees under standard test conditions, and heat significantly affects the efficiency of the solar cells, so that the yield drops.
  • Typical reduction values are around 10%, whereby the conversion of the solar power in an inverter into a grid-compliant alternating current leads to further losses in the order of 6 to 10%. From this it can be seen that approx. 20% or more already due to technical losses in the example given lead to a reduction in the yield to around 800 kilowatt hours per year for a location in Kunststoff. The listed value is as quite realistic energy yield to look at.
  • the present invention has for its object to show a photovoltaic system or a fastening device that leads to an improvement in the efficiency of the photovoltaic systems.
  • the individual modules are electrically contacted via busbars present in the profile strips.
  • the profile strips provided serve primarily to support the high-performance photovoltaic modules and are used according to the invention for contacting the individual modules with one another, so that additional cabling with a large number of plug connections can advantageously be dispensed with.
  • the contact rails used can be oversized so that line losses are kept low. If necessary, there is also the possibility of coating the existing contact rails, which can be made of copper, for example, with an improved electrically conductive material which at the same time has only a low tendency to corrode.
  • the profile strips consist of lateral outer profiles, parallel to them arranged central profiles and transverse intermediate profiles, so that the profile strips are arranged like a checkerboard after assembly and can each individually support a correspondingly dimensioned high-performance photovoltaic module.
  • the outer profiles have a large contact surface for the high-performance photovoltaic modules and a laterally raised edge region which has a conically shaped stop surface on the side facing the support surface.
  • the center profiles have two lateral contact surfaces for the neighboring high-performance photovoltaic modules and an elevated central section, which is trapezoidal and has two conical stop faces facing outwards, while the intermediate profiles can be T-shaped or trapezoidal and have two contact faces pointing outwards.
  • the design of the outer, middle and intermediate profiles ensures that each individual high-performance photovoltaic module is supported in the edge area and is positively accommodated by the conical abutment surfaces or pressure surfaces, taking into account the existing roof pitch, so that a safe and flawless fastening option is created.
  • the use of three different profile designs makes it possible to replace existing high-performance photovoltaic modules at any time in a simple form, for example by removing the intermediate le a possibly damaged photovoltaic high-performance module can be pushed up out of the remaining outer and middle profiles.
  • the end and middle profiles are provided with generously dimensioned contact surfaces, so that the individual modules continue to be supported even if they are pulled apart.
  • the conically shaped stop faces of the outer and middle profiles also ensure that different module heights can be used with the aid of a receiving device and that these can also be used in rows if necessary.
  • a further embodiment of the invention provides that the stop surface of the outer, middle and intermediate profiles are provided with an elastic coating or have an elastic support.
  • the contact surfaces of the outer and middle profiles on the other hand, have a plastic coating or possibly also an elastic coating, so that undesired contacting and short-circuit formation are avoided.
  • the central sections of the central profiles for receiving the intermediate profiles have openings arranged transversely, which are arranged at a distance from the individual module lengths.
  • the intermediate profiles can extend over a module width or alternatively bridge several module rows.
  • a photovoltaic high-performance module in the upper or lower edge area needs to be replaced, it can be removed by pulling it out of the existing profiles. If, on the other hand, it is a question of a high-performance photovoltaic module arranged in the middle row area, the individual module rows can be pulled apart, as already described.
  • the outer and middle profiles are arranged displaceably on a carrier profile fastened to the substructure, the outer and middle profiles being connected to the carrier profile via a connecting profile.
  • a busbar is fastened at least below a support surface of the central profiles or to which the external profiles, or alternatively the busbar is embedded in a groove in the external or central profiles.
  • the busbars are preferably only present in the parallel outer or central profiles, so that the busbars are also arranged parallel and perpendicular and can be connected to one another in the lower region of the entire system by further contact elements.
  • the tracks will be preferably provided with insulation to avoid short circuits.
  • the photovoltaic high-performance modules have at least one power contact on their underside, which comes to rest, for example, on the power rails.
  • the busbars have, at least in sections, one or more grooves or bores arranged laterally or transversely to the longitudinal extension, into which, after assembly, contact elements of the high-performance photovoltaic modules engage, which are connected directly or indirectly to the high-performance photovoltaic modules, the Grooves can be covered by a magnetic shielding cover.
  • the high-performance photovoltaic modules can, for example, also have an accumulator which is connected to the busbars by means of a plug-shaped contact element or a frictional contact, so that good contacting is possible.
  • the individual busbars can protrude at one end from the end face of the outer and middle profiles and, after assembly, bear against a contact rail of an end profile, or can preferably be connected to one another via sockets present in the end faces of the busbars and corresponding plugs on the contact rail.
  • a reversed assignment of the sockets and plugs would also be conceivable.
  • the contact rail of the end profile then only needs to be connected to the other control devices provided for control and monitoring, in particular the inverter, via only a single cable connection.
  • the end faces of the outer and middle profiles are bordered by an end profile which has a recess corresponding to the intermediate spaces, the recess being closed by an air-permeable cover, for example a fly screen.
  • This provides rear ventilation so that overheating of the high-performance photovoltaic modules is prevented and the warming that occurs is reduced by up to 80 degrees to around 40 degrees due to summer sunshine.
  • a rear ventilation of approx. 5 to 8 centimeters in height a length of 5 meters with a roof pitch of 23 to 30 degrees can be achieved Chimney suction effect can be achieved, so that the transfer heat is literally extracted behind the modules and no warming can occur due to the accumulation of heat in the high-performance photovoltaic modules.
  • the current electricity losses can thus be reduced from around 10% to less than 4% and an overall improvement in electricity yield of 6% can be achieved.
  • the end profile serves to connect the busbars embedded in the outer and middle profiles and has a contact rail arranged at the installation height of the busbars, which is connected via further connection elements for electrical contacting to the control devices provided for control and monitoring.
  • the end profiles can be U-shaped, for example, and have legs formed at their ends at right angles to the corners, which are provided at least on one end side with an adjusting screw, which has a pressure plate on the inside against the outer surface, around the end profiles with the outer profiles connect to. This ensures that the end profiles are firmly seated on the lateral outer profiles and also ensure sufficient and reliable contact between the individual busbars.
  • the overall efficiency can be further improved. Under full load, an efficiency of up to 97% can be achieved with a large inverter, which is correspondingly lower under partial load.
  • the measures shown make it possible to increase the efficiency of photovoltaic systems by up to 20%, so that the overall efficiency increases from the current 72% to up to 92%.

Abstract

L'invention concerne un dispositif de fixation, destiné en particulier à des modules (2) photovoltaïques à grande puissance, ce dispositif comprenant plusieurs baguettes profilées (3, 4, 5) destinées à maintenir les modules (2) par liaison de forme. Selon l'invention, pour améliorer le rendement de ces modules (2) photovoltaïques à grande puissance, les différents modules (2) sont mis en contact électriquement par l'intermédiaire de barres conductrices (20) disposées dans les baguettes profilées (3, 4), ce qui permet d'une part, en raison d'une section transversale accrue et de l'absence de câbles de liaison, d'éviter les ruptures de câble et d'autre part, grâce à une connexion améliorée, d'éliminer les pertes dues aux liaisons par câble classiques. Dans un autre mode de réalisation, une ventilation arrière permet de limiter sensiblement l'élévation de température des modules (2) photovoltaïques à grande puissance, y compris en cas de rayonnement solaire intense, de façon à éviter des pertes d'énergie dues à des augmentations de température dans lesdits modules (2).
