Abstract

The present disclosure relates to a frame structure of a photovoltaic module and a production process thereof. The frame structure is made of a composite material, and comprises a supporting arm extending in a first direction; a first mounting arm, a second mounting arm, and a third mounting arm, which are mounted on a same side of the supporting arm; and a fourth mounting arm connecting the second mounting arm and the third mounting arm. The first mounting arm, the second mounting arm, and the first supporting structure form a mounting groove, and the second mounting arm, the third mounting arm, the fourth mounting arm, and the second supporting structure form a connecting groove. The inner wall of the mounting groove and the inner wall of the connecting groove are provided with reinforcing ribs.

Claims (29)

1 . A frame structure of a photovoltaic module, configured to mount a photovoltaic structure,

the frame structure comprises: a supporting arm extending along a first direction; a first mounting arm, a second mounting arm, and a third mounting arm, which are mounted on a same side of the supporting arm; and a fourth mounting arm connecting the second mounting arm and the third mounting arm;
