Profile rail, holding element and solar module assembly comprising same, in particular for a horizontal assembly of solar modules

The invention comprises a profiled rail, in particular for mounting framed solar modules, with a rail body and two support legs, of which at least one projecting in a perpendicular to a longitudinal direction of the rail standing transverse direction of the rail body and the mutually parallel bearing surfaces at different heights with respect to a lower edge of the rail a height distance from each other in a direction perpendicular to the transverse and longitudinal direction pointing height direction, and with a pointing in the transverse direction bearing surface between the support legs, which at least partially bridges the height distance between the support legs.
