  • the present invention relates to a mounting system for mounting solar modules on a substructure and a mounting method.
  • the use of solar modules to generate electricity has become increasingly important in recent years, in the face of rising energy prices and dwindling non-renewable resources.
  • Significant efforts have been made to make solar installations economically viable in order to be able to carry out installations of large outdoor installations efficiently and therefore quickly and reliably.
  • solar modules can be set up with the least possible technical effort at suitable locations and installed there effectively.
  • solar modules are often mounted on substructures in the field, so that solar radiation can impinge unhindered on the solar cell.
  • a disadvantage of such a solution is the fact that still depends on the module width, always after a certain number of assembled modules results in a mounting problem. Is the selected module z. B. slightly wider, such as the intended pitch of the slots, the next mounting position moves with each module further mounted a bit further to the edge region of the respective slot. After the assembly of the x-th module, one then reaches the outermost edge of the relevant slot, so that another module can not be mounted next to it in the longitudinal direction.
  • the invention is therefore based on the object overcomes mentioned disadvantages and to provide a flexible mounting system for mounting solar modules (in particular framed PV modules) on a substructure, which allows mounting modules of different module width in a simple and cost-effective manner. It should be noted that the mounting system must be designed so that it the forces occurring, such. B. withstands wind loads.
  • a first basic idea of the invention is not to realize the assembly of the PV modules by means of mounting elements in a fixed pitch pattern or a fixed grid at defined Kauselementpositionen on the substructure, but to provide a screwless, speak jamming connection with an adapter element, so that the Positioning of the adapter elements on the substructure can be suitably selected according to the selected PV module width.
  • a second basic idea of the invention is to be able to deform the mounting adapter for installation to the extent that it can be mounted, but to prevent said deformation possibility in the mounted state.
  • the mounting adapter has for this purpose a clamping portion and a spring portion.
  • the clamping portion of the mounting adapter can be widened in its effective width for the clamping by the spring portion of the adapter is "effective.”
  • the expansion is only possible as long as as the mounting adapter is not determined by is prevented from bending and thus widening in accordance with overlying PV modules.
  • the mounting adapter without assembled PV modules can be elastically deformed from its clamping position into its mounting position, in that it is pushed onto a profile leg of corresponding width and can be widened. As soon as he has reached the position intended for clamping, he deforms elastically back into its clamping position, which corresponds to the starting position. In this position, the clamping arms of the mounting adapter with corresponding clamping elements on the longitudinal profile carrier interact positively and / or non-positively.
  • PV modules are applied to the top side of the mounting adapter in the clamped position in the mounted state, they form an abutment which counteracts the deformation direction of the mounting adapter and fix the underside of the mounting adapter against the abutment side of the profile leg.
  • the spring travel, the spring section is shortened accordingly and thus the spring arm so to speak “ineffective”, whereby a previously described expansion of the clamping portion and thus a release of the clamping adapter is inhibited from its clamping position by the invention described interaction between mounting adapter, longitudinal profile and PV module a "self-locking" effect, since the necessary spring length for bending the mounting adapter is no longer available when the PV modules fix the mounting adapter in its clamping position.
  • the mounting adapter receives a defined bias by already having a small "pre-bend" in its initial state along the spring section.
