A holding element made of a sheet metal for at least one solar element, more particularly a solar module and/or solar collector, with a base that forms a support surface for the holding element, with two supports for the solar element that protrude up from the base at different heights, and with connecting elements, which are provided on ends of the holding element is disclosed, which has at least one, more particularly hole-shaped, opening and at least one tab, which tab is shaped for being inserted into such an opening. In order to be able to easily install a highly rugged holding element, it is proposed for at least one opening and at least one tab to be respectively provided next to each other on each of the ends, wherein the sheet metal is a metallically coated, more particularly hot-dip coated, sheet steel.

Holding element and system with a plurality of holding elements for at least one solar element

The method relates to a press-hardened component with a tensile strength R>1600 MPa, in particular >1800 MPa, and especially >2000 MPa, wherein the component is manufactured from a steel material, wherein the steel material is a boron-manganese steel, which has a carbon content >0.30 mass %, wherein the steel material is hot rolled or hot rolled and cold rolled to a strip with a thickness of 0.5 to 3 mm, wherein the strip has a thin coating of zinc or a zinc-based alloy and a coating weight of <50 g/mon each strip side of the steel strip.
