MOUNTING SYSTEM, MOUNTING ASSEMBLY, AND SOLAR INSTALLATION

The invention relates to a mounting assembly (1) and a mounting system (2) for planar solar modules (3), comprising: a base rail (4) that can be situated on a roof of a building; at least one L-shaped solar-module carrier (9) which has a retaining limb (10) associated with the base rail (4) and a carrying limb (11) oriented at least substantially perpendicularly thereto, wherein the carrying limb (11) comprises a support for at least one solar module (3) and the retaining limb (10) is designed to be supported, at least in regions, on the base rail (4); a retaining element (19) for fastening the retaining limb (10) on the base rail (4); and a sliding block (29) which can be moved in the base rail (4) and is or can be connected to the retaining element (19) by a screw connection (48) in order to fasten the retaining element (19) on the base rail (4). The retaining element (19) comprises, in the base portion (34), an edge portion (22) which can be placed on the retaining limb (10) and can be interlockingly connected to the retaining limb (10), and said retaining element comprises, spaced apart from the edge portion (22), at least one spacer (28) which projects from an underside (26) of the base portion and is intended to be supported on the base rail (4), which spacer at least reduces a clamping force that can be generated by the screw connection and acts on the retaining limb (10).
