Definitions

  • the invention relates to an arrangement of two adjacent PV module units held by support elements at a predeterminable height above the ground, each PV module unit having a marginal edge to the adjacent PV module unit and a PV module unit edge facing away from the boundary edge having.
  • a supporting framework is usually erected for the multiplicity of priotovoltaic modules, which consists of supports of different lengths.
  • transverse bars are arranged, which extend over the supports of the same length.
  • a plurality of parallel bars is arranged in a grid, which is adapted to the length or width of the photovoltaic modules.
  • the actual framed or unframed PV modules are attached by means of brackets.
  • the shorter supports have a length of about 1, 2 meters and the longer supports can take lengths of up to 3 meters or more.
  • Supports of the known lengths require a secure anchoring in the ground, which in turn causes additional costs in the form of pile work or incorporation of foundations.
  • the high supports offer the advantage that the photovoltaic modules are freely accessible to a fitter from below, without having to stoop or distort them. This is especially important for the subsequent care of the terrain on which the photovoltaic system is. For reasons of environmental protection, this is usually a green area, which must be regularly mowed in the summer.
  • CONFIRMATION OPPE turns and connects at the top.
  • problems may be expected to the effect that the running water runs directly into the support area and there can lead to mud and corrosion.
  • the former causes an uncontrolled sinking of the support elements in the ground and the second in the long term, a weakening of the support elements.
  • the invention is therefore based on the object to provide a structurally simple and inexpensive substructure for a photovoltaic open space generator, which is also suitable for a construction of low height and which avoids the above-mentioned with respect to the prior art disadvantages.
  • the support elements are arranged exclusively on the side of the respective remote PV module unit edge, and that the marginal edges have a smaller distance from the ground than the remote PV module unit edges.
  • This measure ensures that water draining from the PV modules drips onto the surface at the point furthest from the support elements. As a result, it remains dry in the area of the support elements and no undesirable lowering of the support elements into the ground is to be expected. Furthermore, the dry area prevents corrosion of the support elements, which can be made even easier and more cost-effective. In addition, the dryness minimizes or prevents growth on the support elements, which contributes to lower maintenance and servicing costs. Such growth is particularly harmful if it grows through existing joints on the PV module level and thus causes loss of revenue by shading photovoltaic cells.
  • a PV module unit can consist of a single PV module of any size or of a plurality of PV modules, in particular one behind the other.
  • connecting means used hereinafter is to be understood as meaning a single structural component or the commonality of several structural components which are suitable for bridging the distance between the floor supports and at the same time reducing the weight of the components Photovoltaic modules with considered snow load, wind load, etc. to wear.
  • the marginal edge and the remote PV module unit edge of both PV module units run essentially parallel to the ground in a north-south direction.
  • the edge or edge of the module unit is the frame and, when using unframed PV modules, in particular, the glass edges thereof and / or PV modules with bottom rails (backrails) their ends.
  • the support elements have at their head end, in particular centrally to the support element arranged cross member, are provided at both ends fastening points for direct or indirect attachment of the remote module unit edges.
  • a support element then provides two support points for fixing the PV unit available.
  • the PV units themselves may be designed as bearing surfaces, which are arranged at the two ends of the cross member, on which a module frame or a rear rail or other connecting means between two support elements are supported.
  • a single long cross member can be used, which is supported over several support elements away. This offers the advantage that with a more inaccurate mounting of the support elements nevertheless a desired grid spacing for the fastening means can be achieved.
  • the support elements may comprise on the bottom side means, e.g. in the form of a plate, which is to be understood as a constructive measure that prevents unimpeded penetration of the support element in the ground. It may therefore be anti-Eindringbaumaschinemaschine having wing-like ridges in the manner of a ski pole, or flat sheets or concrete slices, etc. In particular, in addition to the anti-Eindringteil this may be provided below with a rod.
  • rod is meant any elongated member, such as a rod. a solid rod, a square tube, a round tube, etc. which is suitable to connect the plate rigidly with a support plate.
  • the rod can be extended at the bottom of the plate by a piece, so that a spike is formed, which is intended to penetrate into the ground.
  • the dome prevents lateral slippage of the ground support and also offers a small contribution to counteract a wind-induced buoyancy. However, the buoyancy force is essentially countered by the dead weight of the assembled PV modules, which prevents the ground support from lifting off the ground.
  • an inclined support surface from which the connecting means between two opposing support elements, so the inclined support surface is in particular designed as a fold, under which any kind of change in direction of the surface of the support plate is understood.
  • a downwardly facing edge has an obliquely downward surface result.
  • the fold itself may be a clear edge, but also a curve or any other suitable shape, which has the desired change in direction of the support surface result.
  • an additional component such. a set sheet metal strip, are used.
  • the measures mentioned offer the particular advantage that the heavy components of the classic substructures such as columns, crossbeams and spars are eliminated and replaced by a variety of light and handy floor supports.
  • This makes it possible to design the distance between the plate and the support surface between 30 cm and 100 cm, in particular between 40 cm and 80 cm, and particularly preferably between 50 and 60 cm.
  • the supports for the photovoltaic modules are thus relatively short compared to the prior art, which reduces the cost of materials. Due to the low overall height, wind can not undercut the substructure and generate correspondingly high buoyancy forces under the photovoltaic modules, as is the case with higher-placed PV modules. The photovoltaic modules are virtually dipping into the landscape and offer little access to wind.

  • rope is intended in the present application as a synonym for any flexible, elongate connection means that is suitable to safely carry the PV module units. These include e.g. a belt, a braid, a foil tape, etc., where there is no material restriction.
  • At least one spacer is fastened on the connection means or on the PV module unit, which establishes a direct contact between the connection means and the PV module unit prevented. Additional spacers are required to prevent collision of adjacent photovoltaic module units. At least one spacer should be arranged at the apex of the v-shaped connecting means, be it as a flat band or as a rail. The equivalent point when using a rope or belt is in the middle of the sagging strap or rope. In the latter arrangement, it is useful if a plurality of spacers are provided, which define a different distance between the rope / belt on the one hand and the PV module unit on the other. Thus, a uniform pressure distribution over the bottom of the PV module unit can take place, which is especially important when intercepting a snow load.
  • this arrangement is intended in particular for low-profile photovoltaic panels.
  • it can also be used for high-build Fields, in particular in the range between 190 cm and 240 cm are used when the outside lying on the field edge support elements are clamped for fixing obliquely or made of solid components, such as IPE-carrier. In this way, darkened greenhouses can be created for the growth of shade trees, which also act as energy suppliers.

Abstract

L'invention concerne un agencement de deux unités modulaires photovoltaïques (11) maintenues par des éléments de soutien (1a, 1b) à une hauteur prédéfinie au-dessus du sol (U). Chaque unité modulaire photovoltaïque (11) présente un bord de délimitation (G) par rapport aux unités modulaires photovoltaïques voisines et un bord d'unité modulaire (12) opposé au bord de délimitation (G). Les éléments d'appui (1a, 1b) sont agencés exclusivement sur le côté du bord d'unité modulaire (12) respectivement opposé et la distance (A) des bords de délimitation (G) par rapport au sol (U) est inférieure à celle qui sépare ce dernier des bords d'unité modulaire (12) opposés. Ainsi, les eaux de pluie évacuées ne s'infiltrent pas dans le sol (U) au niveau des éléments d'appui (1a, 1b) et ne risquent donc pas de provoquer l'affaissement incontrôlé des éléments d'appui ni la corrosion de ces derniers.
