In some embodiments, a first buffer structure is disposed on a side of the carrying portion away from the first cavity, and a second buffer structure corresponding to the first buffer structure is disposed on a side of the upper side 112 opposite to the carrying portion, so as to effectively avoid stress damage to the frame and corner connectors of the photovoltaic module due to excessive assembly force.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the present application, and that various changes in form and details may be made therein without departing from the spirit and scope of the present application in practice. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the application, and it is intended that the scope of the application be limited only by the claims appended hereto.
