Definitions

  • the invention relates to a flat roof attachment for solar modules and in particular for a modular, self-supporting mounting system for mounting an arbitrary number of flat solar modules on flat roofs.
  • roofs are mainly unutilized surfaces which cannot be used for other purposes, they are an ideal location for utilization of solar energy. Mountings for sloping roofs are widely used since the wind-stable attachment on a roof surface is easy to implement.
  • Such a roof attachment is known from document DE 10 2005 033 780 A1.
  • the supporting frame is anchored to a corresponding sustainable sub-construction of the roof.
  • the supports required at the supporting frame penetrate the roof cladding, thereby impairing its function as watertight roof element. In order to counteract this, extensive tightening measures have to be taken at the penetrated spots.
  • flat roof attachments with supporting frames which are solely attached on the roof cladding in a frictionally engaged manner, i.e. which make due without anchoring elements penetrating the roof cladding.
  • the stabilization against wind loads at this supporting frames is due to a high dead weight.
  • the frame parts themselves can be particularly heavy as well, as can be seen from document DE 203 12 641 U1.
  • the supporting frame is provided with receiving devices, like troughs in order to apply a superimposed load with bulk material. Such a possibility is described in document DE 203 11 967 U1.
  • Solar modules of known roof attachments can be arranged without taking the aerodynamic situation any further into account, provided that the modules in the lateral area are arranged in a protruding manner and both their upper surfaces and their lower surfaces are exposed to wind. This requires a particularly high dead weight of the roof attachment in order to render said roof attachment insensitive to wind. This, in turn, has an adverse effect on the statics of the building.
  • the flat roof attachment of document WO 2008/022719 cannot be used as universal self-supporting solar module carrier since solely solar modules of a certain type (size, mounting) can be used and mounted in order to render the flat roof attachment structurally stable.
  • the size of the flat roof attachment cannot be adjusted individually to a certain number of solar modules, either, so that individual modules can be mounted subsequently.
  • the object of the invention is to overcome the above disadvantages, at least in part. It is in particular an object of the invention to provide a modular self-supporting mounting system for mounting an arbitrary number of plane solar modules of an arbitrary type on flat roofs which makes due without an anchoring at the roof construction.
  • the term “self-supporting” means that the mounting system can be set up in a stable manner without a plane module having to be mounted as a stabilizing element.
  • module means that the mounting system can be designed for an arbitrary number of plane modules and can also be expanded later on.
  • a modular self-supporting mounting system for mounting plane modules of an arbitrary type on flat roofs
  • the modular self-supporting mounting system comprises at least one base element for mounting an individual plane module, the base element comprising the following: a first and a second module rail, disposed in parallel alongside to each other; a first and a second front module support having a first length, wherein a first end of the first front module support is attached to a first area of the first module rail, and wherein the first end of the second front module support is attached to a first area of the second module rail; a first and a second rear module support having a second length, wherein a first end of the first rear module support is attached to a second area of the first module rail, and wherein a first end of the second rear module support is attached to a second area of the second module rail; wherein the first length is greater than the second length, and wherein the second ends of the first and second front and rear module supports are adapted for mounting the plane module so that
  • This arrangement leads to a modular mounting system which can be set up in a stable manner independently of the plane module and which makes due without anchorage to the roof surface.
  • This arrangement further allows the mounting of an arbitrary number of plane modules, i.e. of modules from various manufacturers having any size, thickness, mounting points, framed and unframed modules. The mixture of various modules in one set-up is also possible.
  • the self-supporting construction allows for a facilitated assembly of the mounting system. As regards the exchange of damaged modules, one is not tied down to one specific type either. Further, the front cover and the rear cover provide for a streamlined design, wherein the wind pushes the system against the roof surface, thereby requiring less ballast for weighing down the system which has an adverse effect on the statics.
  • the system allows for a low-ballast construction of the roof without anchoring in the roof.
  • the system further allows for a mounting of the plane modules inclined towards the roof so that an edge of the plane module, which is closer to the roof surface, may comprise a prescribed distance to the roof surface, e.g. 20 cm. This allows for a better slipping down of the snow in winter, impairing the function of the plane module to a lesser extent.
  • One embodiment thereof provides a mounting system, wherein each module rail is mounted on at least two supporting devices being able to keep the module rail at a prescribed distance from a roof surface.
  • the assembly system for flat roofs according to the present invention is in particular suited for areas with high precipitation (snow and rain) since the flow of water is not impaired.
  • the modular self-supporting mounting system is designed so that a gap is situated between the plane module and the rear cover, said gap being greater than the prescribed distance between the module rail and the roof surface.
  • the gap serves as a defined venting gap for the drying of the roof surface below the solar module and for the discharge of accumulated heat.
  • the supporting devices are provided with screws, the module rail being fitted onto said screws and screwed together with the supporting device.
  • the screws facilitate the assembly of the mounting systems. Further, the screws can also be used as connecting elements for attaching base elements and extension elements, facilitating the assembly and extension to a considerable extent.
  • the modular self-supporting mounting system further comprises an extension element, wherein the extension element comprises the following: a third module rail, disposed in parallel alongside to the base element; a third front module support having the first length, the first end of which is attached to a first area of the third module rail; a third rear module support having the second length, the first end of which is attached to a second area of the third module rail, wherein the second ends of the third front and rear module supports together with the second ends of a front and a rear module support of at least one of a neighboring base element and an extension element are adapted for mounting a second plane module so that the second plane module forms the prescribed angle to the module rails; a second front cover covering the space between the third front module support and a neighboring base element or extension element; a second rear cover covering the space between the third rear module support and the neighboring base element or extension element.
  • the extension element comprises the following: a third module rail, disposed in parallel alongside to the base element; a third front module support having the first length, the first end
  • the extension element uses the same structural elements as the base element, but in a lower number, thereby facilitating the manufacture and rendering it more cost-effective.
  • the attaching device for mounting a further base element or extension element of the modular self-supporting mounting system is formed by a connecting device between said two module rails so that a rear end area of the first, second or third module rail can be connected to a rear end area of a further module rail.
  • module rails which can be, e.g., part of various base or extension elements can be connected with each other in longitudinal direction.
  • the connecting device can be, e.g., realized by means of holes in the module rails so that the module rails can be assembled by means of the screws or supporting devices.
  • the attaching device for mounting a further extension element of the modular self-supporting system is formed by means of a device attached to the front and rear module supports to which neighboring plane modules, neighboring front covers and neighboring rear covers can be attached.
  • extension elements can be attached to the mounting system “laterally” with respect to the module rail (in contrast to the aforementioned “longitudinal direction”).
  • the front module supports and the rear module supports comprise devices for attaching the plane modules.
  • the devices for attaching plane modules can be adjusted to various module sizes and types.
  • the devices for attaching the plane modules each comprise the following: a profile rail attached to a second end of the module support on which the plane module ( 170 ) can rest; and a module clamp attached to the profile rail.
  • This embodiment allows for the use of a profile rail serving as a rest for the plane module on the one hand and allowing for universal attachment of module clamps on the other hand.
  • plane modules like e.g. photovoltaic modules may often be solely mounted with type-specific supporting devices (module clamps). These supporting devices (module clamps) can be attached to the profile rails in a simple and technically correct manner. Thus, a low-cost, universal mounting system is provided.
  • m base elements and (n ⁇ 1) ⁇ m extension elements are disposed and connected to a m ⁇ n matrix array, wherein m and n are a natural number greater than or equal 1.
  • the mounting system allows for the set-up of module fields of arbitrary size on flat roofs, solely limited by the roof surface.

  • the front cover 140 of the module disposition M 1 has to be attached to a front sheet holder 180 with a screw 161 - 1 , e.g. via a sheet-metal screw.
  • the front sheet holder 180 is connected to the module rail base element 110 -A, e.g. via a perforated fold at the front sheet holder 180 which is screwed with the screw 161 - 2 of the front supporting device 160 - 1 .
  • the embodiment of the module rail described in FIG. 3 is a particularly advantageous embodiment in view of the mounting effort.
  • the module rail base element 110 -A can be extended forwards so that no front sheet holder 180 is required for the foremost (first) module disposition.
  • FIG. 4 shows a 3-D view of a base module according to FIG. 3 .
  • This view shows the module clamps 200 which can be attached to the profile rail 120 - 5 and 130 - 5 . Since the profile rails 120 - 5 and 130 - 5 universally allow for the mounting of the most varied holders, manufacturer-specific module clamps (holders) can also be used.
  • FIG. 5 shows the 3-D view of FIG. 4 , which is provided with lateral covers 210 . Due to this, a completely closed body is formed, which is, however, open at the bottom, which enhances the above-described aerodynamic effects of the ballast-reduction.
