Abstract: The present invention relates to a longitudinal profile for a mounting system for solar modules, comprising: at least one stop area which is designed to fasten the longitudinal profile to a transverse profile, wherein the at least one stop area has at least one support surface for support on the transverse profile, at least one head area which is connected to the at least one stop area via at least one connecting portion, wherein the at least one head area has at least one bearing surface for at least one portion of a module frame of the solar module, wherein the at least one head area has at least one engagement projection which is configured as a point of engagement for a fastening device. The present invention further relates to a mounting system comprising such a longitudinal profile.

Abstract: A mounting system for photovoltaic modules includes at least two profile-shaped cross rails arranged parallel to each other and configured to hold several PV modules. Each cross rail includes plane supporting surfaces. The PV module is mounted by placing it onto the at least two cross rails so that the at least two holders lay flat on the plane supporting surfaces of the at least two cross rails. The PV module is then moved in a joining direction perpendicular to the cross rails while lying on the plane supporting surfaces so that either a recess engages with an integrated protrusion or a protrusion engages with an integrated recess. A retaining safety device is disposed between at least one cross rail and its corresponding holder and is configured to counteract a move against the joining direction.
