Mounting system for photovoltaic modules and components of a mounting system for photovoltaic modules for improving installation

A mounting system for photovoltaic modules

• comprising:
• a rail transverse connector (10, 27) comprising a pair of angle rails which are inserted into each other in a longitudinal direction, wherein
• the angle rails (28) have a fixedly predetermined fixing device (30) in end areas (29, 33) each situated on the outside for the connection to a bottom profile rail (05) and wherein a variable overlap (31) of the angle rails (28) which are inserted into each other for predetermining the length of the rail transverse connectors (10, 27) is set by means of a fixing element (32) for fixing the relative position of the angle rails (28) to each other in the area of the overlap (31) situated on the inside;
• and/or
• a holding element (07) having a base element for being connected to a bottom profile rail and a rocker element, which is mounted with respect to the base element so as to be pivotable about a pivoting axis, for being connected to a photovoltaic module of a photovoltaic module,
• further comprising
• a preload element which interacts with the base element (08) and the rocker element (09) in such a manner that, when the rocker element (09) is accelerated only by the weight, a rotation of the rocker element (09) with respect to the base element (08) is prevented and wherein, in case of an additional acceleration, an adjustment of the rocker element (09) with respect to the base element (08) is made possible;
• and/or
• a bottom profile rail system (24) comprising at least two rows of bottom profile rails serving for the fixation of holding elements for holding photovoltaic modules, wherein each row of bottom profile rails comprises at least two bottom profile rails,
• wherein
• a connection element (11) is disposed between each two adjacent bottom profile rails (05);
• and/or
• a connection element (11), a base body (12) realized as a U-profile rail and having two parallel side legs (13) and a connection section (14), wherein both side legs (13) have a projection (16) on a free end (15) facing away from the connection section (14), said projection (16) being realized with the base body (12), wherein, in the mounted state, the side legs (13) are guided in channel sections (26) of the bottom profile rail (05) in such a manner that a wall of the channel sections (26) runs above the free ends (15) of the side legs (13), wherein the projection (16) is realized in such a manner that it does not project at the top beyond the wall of the channel sections (26) in the mounted state.
