Abstract: A profile rail comprising in a cross-sectional view: a base plate which forms a bottom side of the profile rail and which is flat in sections or completely flat; a first and a second receiving cavity for a rail support which cavities are both partially closed laterally in outward direction and which respectively include a lateral opening, wherein the two lateral openings are oriented in opposite directions; and a third receiving cavity which includes an opening that is oriented away from the bottom side of the profile rail and which includes an inner profile for attaching module attachment elements.

Abstract: The invention relates to a solar module attachment, comprising a Z-support (2), the one Z-side (2.1) of which is used directly as a roof attachment or can be connected to roof hooks or support posts in the case of a mounting system, while clamps (5) can be displaced over the other Z-side (2.2), the attachment means engaging in said clamps in order to fix solar module frames (1).

Abstract: The invention relates to a connection slider for attaching two adjacent frames of photovoltaic modules or collector modules on a profile rail, the connection slider comprising: a main element; two mandrels which extend from two surfaces of the main element oriented in opposite directions, wherein one respective mandrel is insertable into one of the adjacent frames; and a transversal element protruding from the main element, wherein the transversal element has an opposite profile adapted to a profile of the profile rail for providing a form locking connection with the profile rail.

Abstract: The invention relates to a profile rail in particular for supporting framed solar modules, including a rail element and two support arms, wherein at least one of the support arms protrudes from the rail element in a transversal direction (q) that is perpendicular to a longitudinal orientation of the profile rail, and wherein the support arms include support surfaces that are parallel to one another are at different elevations with respect to a lower edge of the profile rail with an elevation offset from one another in an elevation direction perpendicular to the transversal and longitudinal direction, and a support surface oriented in the transversal direction and arranged between the support arms, wherein the support surface bridges the elevation difference between the support arms at least partially.

Abstract: The invention relates to a connectable profiled mounting rail, comprising longitudinal webs (3) for connecting the elements to be mounted, wherein the basic profile has a discontinuous, essentially rectangular surface line (4). On the one side, a connection profile (5) for attachment of the profiled mounting rail (1) is provided. The connection profiles (6, 7) located on the opposite side are arranged in such a structural manner that a second profiled mounting rail (2) which has the same profile cross-section and is rotated by 180° can be connected in a positive fit to the first profiled mounting rail (1) by inserting the connection profiles (6, 7) into each other.
