Definitions

  • the invention relates to a support structure for a photovoltaic (PV) system, which can be designed in particular to support upright, preferably bifacial, photovoltaic modules (bifacial PV modules can receive sunlight from the front and back and convert it into electrical current).
  • the support structure has a plurality of posts which are attached, in particular anchored, to or in the ground, with bars attached to the posts which connect two adjacent posts to one another.
  • the invention relates to a PV system with several, preferably bifacial, PV modules that are arranged upright on such a support structure.
  • the term "upright” can also be understood to mean designs in which the PV modules are installed at an angle of 80° or even just 70° to the horizontal.
  • the invention also relates to a method for mounting an adapter element as previously explained on a post of a supporting structure of a PV system.
  • the supporting structure has several posts that are attached, in particular anchored, to or in the ground, and bars are attached to the posts in order to connect two adjacent posts to one another, wherein the bars are each attached to one of the posts by means of at least one separate adapter element, preferably independently of the PV modules of the PV system.
  • Support structures composed of vertical posts and horizontal beams are already being used to construct PV systems with on right-standing PV modules that are bifacial in design and can therefore receive sunlight from both the front and the back.
  • the invention has set itself the task of providing a support structure for a PV system which can safely absorb the high wind loads occurring when using upright PV modules, even with very large module sizes, and at the same time enables a high electrical efficiency of the PV system as well as an efficient construction of the same.
  • the features of claim 1 are provided according to the invention in a support structure for a PV system. It is therefore proposed according to the invention to achieve the object in a support structure of the type mentioned at the beginning that the bars are each connected by means of at least a separate adapter element are attached to one of the posts and that the respective adapter element is supported flatly on at least two surfaces of the post, which run in different directions, each transverse to a longitudinal axis (vertical z-direction) of the post.
  • the said surfaces on which the respective adapter element is supported can be outer surfaces and/or inner surfaces of the post (as will become apparent from the exemplary embodiments).
  • the object mentioned at the outset can also be achieved with the combination of features of independent claim 2:
  • the bars are each fastened to one of the posts by means of at least one separate adapter element, that the respective post has at least one through opening and that at least one adapter element is inserted into the respective through opening or is led through the through opening.
  • Such a support structure can therefore be used to support bifacial PV modules upright, i.e. to hold them in position.
  • the invention proposes to guide the adapter elements through a wall of the post before they are connected to the associated bolt.
  • the separate adapter elements are preferably detachably connectable to the post and the bolt, for example via a screw connection and/or a toothing.
  • a particular advantage of this approach is that, unlike previously known approaches in which adapter elements create a connection between a module frame of a PV module and a post, the bars and posts can first be connected to one another using the adapter elements, independently of the installation of the PV modules, in order to initially provide the supporting structure with essentially rectangular installation fields (for example, installation fields in the form of a parallelogram are also possible, for example if the posts are installed at an angle in the ground).
  • the PV modules can then be inserted into the installation fields and connected to the respective bar and/or post, entirely independently of the installation of the adapter elements.
  • the PV modules can have their own module frame, with the help of which they can be installed on the respective bar and/or post.
  • the bars run exclusively horizontally, i.e. the bars do not enclose the PV modules (as a module frame does).
  • the respective adapter element can have elongated holes (preferably running in the z-direction) which allow a bar at different z-heights to be mechanically connected, preferably screwed, to the adapter element.
  • Each of the adapter elements can provide at least one holding surface on which an associated bolt can be mounted.
  • the respective adapter element forms or provides at least one holding surface for holding one of the bolts on at least one side, preferably on both sides, of the post (relative to a longitudinal direction of the bolts) on which the adapter element is mounted.

It can also be seen in Figure 18 that the space between the two holding surfaces 6 (on the left side of the post) is kept at least partially free. This creates space for a longitudinal adjustment of the bolt 3. It can also be seen in Figure 18 and in other of the design examples that the support surface 9a, which prevents the adapter element 4 from tipping, extends laterally beyond the bolt 3 (in the plane of the drawing and transversely to the longitudinal direction of the bolt 3).
