[0032] To facilitate the description of the embodiments of the present application, a first direction and a second direction are provided to assist in the description, wherein D1 in the drawing represents the first direction, and D2 represents the second direction, the first direction and the second direction are perpendicular to each other.

The arrangement of the bending parts 2 strengthens the overall strength of the purlin 400, and the attachment of the bending parts 2 to the base 1 increases the thickness, which can improve the support stability of the purlin 400 to the photovoltaic module 100, and the wave of the photovoltaic module 100 mounted on the purlin 400 can also be improved to a certain extent.
