Abstract: A fastening of a support rail for a photovoltaic module to a trapezoidal rib of a trapezoidal sheet. The support rail comprises an undercut groove with a groove opening. The trapezoidal rib comprises an upper side and a slanted side. The support rail is positioned transversely to the trapezoidal rib. The fastening includes at least one retaining element comprising a fastening section fastened to the slanted side of the trapezoidal rib, and an engaging extension non-detachably arranged thereon. The engaging extension engages the undercut groove in an engaging position. The engaging extension is insertable through the groove opening into the undercut groove of the support rail in a loose position that is rotated relative to the engaging position. The support rail is held down against the upper side of the trapezoidal rib by the engaging extension. The at least one retaining element is arranged either left or right of the trapezoidal rib.

Abstract: A holder for a profiled rail comprising a holding edge and a for carrier component includes a base body, a clamping element, a screw connection, and a rotary joint. The base body comprises a supporting surface configured to have the profiled rail be placed thereon, a holding-down strip which holds down the holding edge against the supporting surface, and a first opening. The clamping element comprises a second opening. The screw connection passes through the first and second opening and is fixable on the carrier component. The rotary joint comprises an axis of rotation arranged parallel to the supporting surface and to the holding-down strip. The clamping element clamps the profiled rail against the base body with the screw connection. On the base body, the clamping element is guided radially with respect to the axis of rotation between an open and a closed pivot position with the rotary joint.

Abstract: An end clamp for fastening a framed PV module on a carrier profile includes a first and second part with respective tooth systems corresponding to each other. The first and second parts together comprise a first section which holds down a frame of the framed PV module onto a surface of the carrier profile, a second section which laterally fixes the frame, a third section with an opening to have a screw pass therethrough, and a fourth section which supports the end clamp on the surface of the carrier profile. The first and second parts slide one inside the other parallel to the first and second sections in at least one discrete position corresponding to a specific frame height provided between the surface and the first section. The first and second parts thereby have one respective remaining degree of freedom and a clearance fit in two other degrees of freedom.

Abstract: A mounting system for photovoltaic modules includes at least two profile-shaped cross rails arranged parallel to each other and configured to hold several PV modules. Each cross rail includes plane supporting surfaces. The PV module is mounted by placing it onto the at least two cross rails so that the at least two holders lay flat on the plane supporting surfaces of the at least two cross rails. The PV module is then moved in a joining direction perpendicular to the cross rails while lying on the plane supporting surfaces so that either a recess engages with an integrated protrusion or a protrusion engages with an integrated recess. A retaining safety device is disposed between at least one cross rail and its corresponding holder and is configured to counteract a move against the joining direction.

Abstract: An apparatus for fastening a mounting rail includes a retaining element comprising a supporting surface for a contact side of the mounting rail, a gripping extension projecting from the supporting surface which engages behind the retaining edge, a first elongated hole disposed transversely to the mounting rail configured to have a threaded shaft pass therethrough, and bracing slopes. A clamping element comprises a second elongated hole disposed transversely to the mounting rail configured to have the threaded shaft pass therethrough, and mating slopes. Nuts engage the threaded shaft. The retaining element and the clamping element are arranged axially between, and are braced together by, the nuts, so that the clamping element and the mounting rail advance toward each another and the mating slopes slide downward on the bracing slopes. The mounting rail is thereby clamped against the gripping extension by the clamping element and is held down on the supporting surface.

Abstract: The present invention is directed to a fixture for attaching a profile rail having an undercut longitudinal groove to another component, the invention includes the arrangement of the fixture.

Abstract: A support rail for a row of PV modules includes an outer hollow rail, a first inner hollow rail comprising a metal, and an insulating device configured to electrically separate the outer hollow rail from the first inner hollow rail. The first inner hollow rail is accommodated within the outer hollow rail via the insulating device and is held in all directions transversely to the support rail in a positive-locking manner within the outer hollow rail by the insulating device.
