solar Panels are known, and indeed in many different ways versions and formations. These are usually photovoltaic or solar thermal Modules that have a substantially rectangular or square base and a few millimeters, usually a few centimeters, z. B. up to 15 cm, are thick.

Such Solar modules are preferably placed on roofs and must there be attached accordingly, so that the solar modules both at Storm and wind, but also on rain and snow loads safely on remain the roof.

It There are already a number of technically sophisticated proposals for brackets of solar modules. These brackets are on the one hand regularly bolted together or assembled equipment with the pad, z. As the roof, can be connected and on the other hand then the top side of the desired Record solar module and also have the known brackets options to securely fasten the solar modules to the brackets.

task It is the present invention, the previous brackets On the one hand, the costs for the brackets drastically on the other hand also the assembly of the solar modules perform faster on the roof to be able to.

The Invention solves the task by a holder with the features after Claim 1. Advantageous developments are described in the subclaims.

According to the invention the entire bracket for the solar modules essentially only a single part, namely a trough-shaped Recording, which has a bottom and a top, wherein the top to the bottom at a predetermined and desired angle is inclined. About that In addition, sufficient stiffeners in the entire bracket designed to with the effects of Wetterunbillen on the solar modules to avoid deformation of the entire bracket and secure Stop the solar modules to allow.

The inventive holder Above all, it is also suitable for solar modules on flat roofs install, it allows by their standard prefabrication in one Plastic production extremely cheap production prices for the Bracket itself, and most of all, it allows it, that the entire assembly the holder only consists in the holder itself on the Afterwards, the solar module can be attached immediately afterwards be attached to the bracket.

By the trough-shaped Training it is also possible that the holder receives inside a Gewichtsungsgut, z. As sand, concrete or split or the like., So to the total mass increase, and that it leads on the one hand overall to increase a roof load, but on the other hand also the inertia the entire facility increased and thus still much better than before against the effects by storm, wind, etc. and this with a very simple Medium.

The inventive holder spares the previous metal scaffolding for attachment and because these metal scaffolding in contrast to the plastic also constantly are subject to corrosion and thus also a care and Require maintenance, is a further particular advantage of the holder according to the invention, also to reduce the after-sales maintenance and service costs.

The inventive holder can be used on any roof construction, as already mentioned on flat roofs and only one single plastic production manufacturing step is needed, around the bracket then in large numbers to extremely cheap To produce prices.
