Abstract: The invention relates to a mounting system, which is configured for mounting at least one photovoltaic module (20) and a solar collector (30) on a substructure suitable therefor. The mounting system (1) comprises at least one U-shaped mounting carrier (2) for fastening the at least one photovoltaic module (20) and for accommodating at least one solar collector (30), the U-shaped mounting support being fastened to the substructure by means of a mounting rail (3), wherein the mounting carrier (2) has support clamping receptacles (9) for fastening the at least one photovoltaic module (20) to at least one of the outer surfaces of the mounting carrier.
