Description

The invention relates to a one-piece monolithic support system for arranging a plurality of solar modules / solar collectors on an angular support surface.

Supporting system for the arrangement of solar modules / solar collectors for the production of electrical energy or heat energy from solar energy are known in various embodiments. In this case, the solar modules / solar collectors, which generally have a rectangular, flat shape, are arranged on surfaces which ensure the greatest possible shade-free sunlight penetration.

Preferably, in this case, the assembly of the solar modules / solar collectors takes place parallel to a nearly flat or slightly inclined roof surface or outdoor area, by means of a support structure, which has arisen from a component only by shaping, as a so-called Flachdachaufständerung or elevation, which is formed with an angle of attack Approximately takes into account the angle of incidence of sunlight.

The support system, consisting of only one component, solar modules / solar panels can be directly attached.

The supporting systems ( 1 ) and ( 2 ) consist of an intelligently shaped retaining clip that can be screwed, glued or ballasted on roofs, flat surfaces, outdoor areas. This consists of steel, galvanized steel, aluminum alloys, steel alloys, plastics or epoxy resins. Plastics and epoxy resins may be fiber reinforced.

The support system ( 1 ) and ( 2 ) realizes the required module inclination without additional components. Both types ( 1 ) and ( 2 ) but can also serve as a basis for advanced constructions, it can be connected more support profiles on which then solar modules / solar panels are attached directly.

All typically so-called flat roof mounting or outdoor mounting systems, which are used in various embodiments, are multi-part. They typically consist of a base support profile, further support profiles, which serve to produce the module inclination, so-called stiffening profiles and distribution yield profiles, which serve to fasten the modules.

From the DE 10 2007 023 177 is a device for arranging photovoltaic modules on a support surface with at least one cross member for supporting the photovoltaic modules and at least one support member for spaced supporting the at least one cross member over the support known in the assembled state, at least one cross member with at least one support member by means of a positive or non-positive connection connects. With such a device, the photovoltaic modules on the one hand in a so-called Flachdachaufständerung or a Aufständerung be placed on other surfaces with the module surface in a tilt angle that corresponds to an improved or optimal average angle of incidence over the year and the sun following one day, on the other hand Such a device by the additionally often required cross member and support elements a not inconsiderably increased weight, so that this device is then suitable for Flachdachaufständerung if the corresponding static conditions are given or photovoltaic system is designed only in size, the present static Conditions of the building and its roof construction corresponds. For a Aufständerung of modules on floor surfaces, such a device but only as appropriate if the installation area is sufficiently secured so that damage of any kind can be prevented at the modules. In addition, the area occupied by modules is not suitable for further use due to the embodiment of the device for other purposes.

From the DE 10 203 19 065 U1 is a support structure with one or more solar modules known, which is particularly suitable for outdoor installation. This support structure consists of a plurality of spaced apart in a longitudinal direction and anchored to the base first carriers; at least one longitudinal side member mounted on the first carrier; a plurality of longitudinally spaced, transversely extending to the longitudinal direction and inclined to the horizontal in a transverse cross member, which are mounted on the side member, wherein the module assembly is held on the cross member. A disadvantage of this support structure is that a large-scale solar or photovoltaic system can be installed only with a very high cost and the modules are mounted in cross members, which are fixed in their focus on a support bracket. Due to the angularly fixed rectangular modules, the modules offer a considerable wind attack surface, so that in a strong storm or gale-force wind gusts large torques occur that significantly affect the positional stability of the modules and exert extreme forces on the fasteners, which damage the system can. But also another Land use among the modules seems very unlikely.

From the DE 203 257 U1 and the DE 10 2005 023 971 B4 are known devices for Freilaufaufständerung of solar modules, consisting of several erected and anchored in a row posts and at least one, approximately parallel to the post row extending side rail or where the modules are fixed via a stiffened frame, with the cross member on the post is attached. These outdoor elevations are installable for large-scale solar or photovoltaic systems only with a very high cost and make no further use of space among the modules possible.

Object of the present invention is therefore to provide a support system with an inclined support surface for the arrangement of solar modules / solar panels for roof and Freilandaufständerung, on a variety of modules cost, without additional support, supports, frame and with little effort in multiple Rows can be arranged to a large-scale solar system and which is absolutely stable even with an extremely attacking wind load in itself and ensure a safe and stable position of the modules, which covered by the modules area is not available for further use.

The present invention will be described in more detail below by means of an embodiment with reference to the accompanying drawings.

According to the invention, this object is achieved with a one-piece support system ( 1 ) or ( 2 ), which consists of a self-supporting construction formed from a component, which can be formed of different materials, with an angle α extending support surface (A), (B), (A '), (B') and one at an angle β extending base area, consists. The upstands (D), (E), (D '), (E'), the connections between the base and the support surface at an angle γ and δ. Depending on the field or roof surface, the support system ( 1 ) or ( 2 ) are used. The interrupted and uninterrupted surface may be drilled or punched, laser cut, recessed or otherwise apertured to assist in the intended use. By additional edgings, transformations in the partial surfaces, the stability of the support system can be increased.

Due to the design of the support system with preferably identical components, the condition is given that the Freilandaufständerung or Dachaufständerung of solar modules / solar collectors can be designed with a freely selectable large-area bearing surface.

The bearing and bearing protection, the attachment of the support system on the roof or outdoor area can depending on the static influences (Schneeeinkwirkung, wind action, other static effects) by ballasting, insert of mass-containing components (concrete block, steel plate, water tanks, bulk material trays, etc.), force-fit connections to the substrate (anchorages by screwing, plugging, mounting, gluing) or positive connection (anchoring by jamming, plugging, under hooking).

In order to achieve a simple and stable attachment of the modules on the support surface of the support system, the connecting module holder are directly with connected to the support system. The module holders are designed so that they anchor against the support system during attachment, but that they can also solve again, remove and replace.

The present invention will now be further described by way of example with reference to the accompanying drawings, in which:
