9. A photovoltaic system, characterized by a main beam, a photovoltaic module and a mounting arrangement for a photovoltaic module according to any one of claims 1 to 8;
the main beam is arranged on the lower surface of the photovoltaic module;
the purline body is sleeved on the main beam, and the clamping part hooks the upper surface of the photovoltaic module;
the distance between the first opening end and the second opening end is adjusted through the locking pieces, so that the purline body is locked on the main beam, the clamping portion is driven to apply force downwards to the end portion of the photovoltaic assembly, the pressing block is driven to move upwards along the first inclined portion and apply force upwards to the middle portion of the photovoltaic assembly, and therefore fixing of the photovoltaic assembly is achieved.
10. The photovoltaic system of claim 9,
the cross section of the main beam is D-shaped, the main beam comprises a plane portion and a circular ring portion, the plane portion and the circular ring portion extend along the length direction of the main beam, the circular ring portion is attached to the inner side wall of the purlin body, and the plane portion is abutted to a bottom plate of a pressing strip arranged in an opening of the purlin body.
