The photovoltaic module has a frame with an inwardly projecting frame underside. The frame underside of the photovoltaic module rests directly on an upper side of the module carrier and can be held down by means of the displaceable holding element against the upper side of the module carrier. The displaceable holding element can be fastened to the module carrier at a desired location by means of a screw connection. The screw connection must be actuated at the back of the photovoltaic module and inside the module carrier.

Out EP 2 458 301 A2 a device for arranging at least one solar module is known. The device comprises a support element on which a displaceable fastening element is provided. The slidable fastening element has a hook-shaped end region which can be brought into engagement with a frame underside of a frame of the solar module. The frame base rests directly on the displaceable fastening element, which causes a lifting and holding the solar module during assembly. The slidable fastener is attached to the support member at a desired position by means of a three-piece threaded connection.

An object of the invention is to provide a device for holding solar module frame, which is simpler and can be attached by means of the solar module frame assembly friendly.

The object is achieved with the device specified in claim 1. Advantageous embodiments and a method for holding a solar module frame by means of such a device are specified in the subclaims.

The holding device according to the invention is provided for such solar module frame having inwardly projecting frame bottoms and perpendicular frame outside. The device comprises a frame carrier and a hook element. The frame carrier includes a first support leg for supporting the inwardly projecting frame underside of such a solar module frame. The first hook element is slidably disposed on the frame carrier for engaging behind the inwardly projecting frame underside. Characteristic of the device is that the frame carrier has a second support leg for supporting the vertical frame outside of the solar module frame, in particular against slope. The hook element is displaceable in a closing direction to the second support leg. The closing direction is preferably perpendicular to the second supporting leg. It is also provided that between the frame support and the hook element, a latching connection is arranged with a plurality of series-connected, which allow a displacement of the hook member in the closing direction and lock against the closing direction.

In one embodiment, the hook element engages around the first support leg in a closed position, preferably on three sides, that is to say the hook element can guide around the first support leg on three sides. In a further embodiment, an opening is included in the frame carrier through which the first hook element passes. The opening can also act as a sliding guide. In a further embodiment, the hook element has on the side of the second support leg, which points in the closing direction, via a tool engagement for a tool.

In a further embodiment, the latching connection has a series of latching teeth on the hook element and a latching hook interacting with the row of latching teeth on the frame carrier. Alternatively, the latching connection may comprise a series of ratchet teeth on the frame carrier and a snap hook cooperating with the row of ratchet teeth on the hook element. The snap hook can be designed as a bending beam and act on the hook element against the first support leg.

In a further embodiment, the device for holding a second such solar module frame has a second hook element, which is displaceable on the frame support and laterally offset from the first hook element and is displaceable in the same closing direction to the second support leg. Between the frame carrier and the second hook element a latching connection is arranged with a plurality of series-connected, which allow a displacement of the second hook element in the closing direction and lock against the closing direction. In this embodiment, the first support leg for supporting the inwardly projecting frame bottom and the second leg surface for supporting the vertical frame outer sides and the second solar module frame is provided. Preferably, the two hook element, the solar module frame in the region of two adjacent Behind frame corners engage, so that the frame support can be made compact.

In further embodiments, the device is provided for holding two or four solar module frames, wherein an extension direction parallel to the first and second support legs is present, and the device is extended such that the features of the device are designed to be functionally symmetrical with respect to a plane of symmetry. Preferably, the features are also structurally symmetrical.

For mounting a solar module frame by means of one of the aforementioned devices, the first solar module frame is first placed on the frame carrier, wherein the hook element is in an open position and the inwardly projecting frame bottom comes to rest with the first support leg and the vertical frame outside with the second support leg. In a second step, the hook element is displaced in the closing direction, wherein one of the successive joining positions is taken and by means of the hook member, the inwardly projecting frame bottom is fixed against the first support leg and the vertical frame outside against the second support leg.

The device can be easily manufactured. Thus, the frame carrier and the hook element can be manufactured to production of extruded parts. In addition, it is possible that the device consists of low component of the frame support and one or more hook elements. Wearing the underside of the frame and supporting the frame outside facilitates installation. Thus, the solar module frame placed on the frame support before moving the hook element and is also secured against downgrade, and it is not necessary, the solar module frame while moving up or hold. In addition, the device can be operated without screws. Furthermore, various solar module frame can be mounted with different width frame bottoms by the latching connection. Another advantage is that the maximum displacement of the hook element is clearly limited, so that damage to the solar module frame is excluded.
