Mounting system and a method for mounting photovoltaic modules

A method for mounting a photovoltaic module onto at least one mounting rail using a plurality of mounting elements, each comprising a first portion and a second portion, the method comprising:

• providing a frame for the photovoltaic module with at least one opening formed as a through hole through the frame at a lateral side or at a bottom side of the frame, the bottom side being opposite to a light incidence side of the photovoltaic module, and the at least one opening formed as the through hole having a closed and continuous perimeter, the frame having a protrusion that is a portion on the bottom side extending parallel to the light incidence side and comprising the at least one opening;
• hooking the first portion of one of the plurality of mounting elements into the at least one opening of the module frame to provide an interlocking connection, the first portion comprising a plate shape with a cut-out part configured to receive the portion on the bottom side of the frame upon insertion of the one of the plurality of mounting elements into the at least one opening of the frame, wherein hooking the first portion into the at least one opening includes rotating the one of the plurality of mounting elements relative to the frame;
• and
• fixing the second portion to the at least one mounting rail, thereby securing the frame to the at least one mounting rail.
