Mounting brackets for direct, point-based attachment of solar modules to vertical surfaces, such as facades

Abstract

(Main claim) Clamp for fastening a solar module to a facade, characterized in that the clamp has a substantially U-shaped form with two legs, each leg having a slot into which a frame of the solar module is inserted.

Description

Technical field

[0001] The invention relates to a holder for attaching commercially available, framed solar modules to building facades, in particular for the point-based, railless mounting of photovoltaic modules on vertical or inclined surfaces. State of the art

[0002] Conventional mounting systems for facade-integrated photovoltaics typically use continuous mounting rails, frame constructions, or clamping systems, which either result in high material costs, require significant installation effort, or restrict the design freedom of the facade architecture. Point-fixing solutions are known, but often require special module frames, drilling into the module, or complex holding mechanisms. Object of the invention

[0003] The object of the invention is to provide a simple, cost-effective and easy-to-install clamp with which commercially available framed solar modules can be securely and precisely attached to facades without requiring additional rail systems or modifications to the module frame. Solution to the task

[0004] The problem is solved by a holder according to claim 1. • The holder according to the invention has a substantially U-shaped geometry with two legs, each having a slot. The frame of a solar module is hooked into these slots. To attach a solar module, two holders are used in the upper area and two holders in the lower area of ​​the module. • For positioning modules one above the other, there is a center support; it is slightly longer and has slots facing two directions.

[0005] The bracket is attached to the facade or substructure via a fastener, in particular a screw connection. The module frame is held securely in place by being inserted into the slots of the legs. Advantageous embodiments • The holder is made of metal, in particular coated steel, aluminum or stainless steel, and is designed as a single piece. • The slots are designed to accommodate different module frame thicknesses. • The holder is available in shapes suitable for top, bottom and middle. • The bracket is designed for mounting on vertical or slightly inclined facades. Brief description of a drawing Fig. Figure 1 shows a perspective view of a holder according to the invention. Fig. Figure 2 shows a perspective view of the variant below. Fig.Figure 3 shows a perspective view of the middle variant when the modules are positioned one above the other. Summary

[0006] The invention relates to a U-shaped holder with slotted legs for the point-fixing of solar modules to facades. The module frame is hooked into the slots and securely held by means of several holders. The solution enables simple, cost-effective and flexible facade mounting of photovoltaic modules.

Claims

[1] (Main claim) Clamp for attaching a solar module to a facade, characterized by that the clamp has an essentially U-shaped form with two legs, each leg having a slot into which a frame of the solar module is inserted. [2] Clamp according to claim 1, characterized by , that two clamps are provided in the upper area and two clamps in the lower area of ​​the solar module for fastening. [3] Clamp according to one of the preceding claims, characterized by , that the clamp has slots facing upwards and downwards in order to line up solar modules downwards as well. [4] Clamp according to one of the preceding claims, characterized by that the clamp is made in one piece.
