[0034] The assembly frame provided by the utility model is provided with the first bending part 1 on at least one of the C face 400 and the inner B face 300, and the extension direction of the first bending part 1 is perpendicular to the first direction, that is, the extension direction of the first bending part 1 is consistent with the direction of the gravity of the photovoltaic panel, so that the first bending part 1 can play the role of a reinforcing rib, increase the structural strength of the assembly frame, and have better stability of the frame, so as to meet the load performance requirements of different version assembly frames.
[0035] In some embodiments, the top and / or bottom of the inner B face 300 is provided with a first bending part 1; since the photovoltaic panel is installed to the slot 500, the main weight of the photovoltaic panel acts on the inner B face 300, and therefore it is preferable to provide the first bending part 1 on the inner B face 300; the first bending part 1 can be provided at any position of the inner B face 300, and it is preferable to provide the first bending part 1 at the top and / or bottom of the inner B face 300, so as to match the bending structure of the inner B face 300 itself, to have better stability, and to facilitate processing.

[0043] In some embodiments, the plate body is a steel plate; that is, the assembly frame is a steel assembly frame.

[0047] In some embodiments, the assembly frame selects a closed frame structure design, the height of the frame B surface is 20-50mm, for example, the frame height can be mainly 30mm, 33mm, 35mm; the width of the frame C surface 400 is generally recommended to be 10-40mm; the width of the frame A surface 100 is generally recommended to be 5-13mm; the above frame specific size can be designed and customized according to the requirements.
[0048] Further, in the process of making a photovoltaic module, the steps include: welding the cell pieces into a cell string through a welding strip, the number of cell pieces is defined according to the version requirements; laying the glass and the first layer of encapsulating film; arranging the cell string in the module, the positive and negative poles of the cell string are designed in parallel or series, and the specific design is defined according to the version requirements; welding the cell string and the cell string by a busbar and reserving the busbar lead-out wire; laying the second layer of encapsulating film; laying the backboard material; laminating; edge cutting; framing; installing the junction box; the photovoltaic module made of the assembly frame can significantly increase the strength and stability.
[0049] In addition to the above-mentioned assembly frame, the utility model also provides a photovoltaic module comprising the above-mentioned assembly frame, and the other parts of the photovoltaic module refer to the related technology, and details are not repeated herein.
