Briquetting assembly and solar photovoltaic power generation system

The utility model discloses a briquetting assembly and a solar photovoltaic power generation system. The briquetting assembly comprises a clamping block, a briquetting and a lifting device. The clamping block can be clamped on the rail; the lifting device is installed on the clamping block, and the pressing block is rotatably installed on the lifting device and can be driven by the lifting deviceto ascend and descend. The pressing block comprises a pressing block body and supporting legs, the pressing block body is connected with the lifting driving device, the supporting legs are fixed to one side of the pressing block body, and the width of the supporting legs is smaller than that of the pressing block body; solar panels can be pressed on the two sides, adjacent to the supporting legs,of the pressing block body at the same time. When the solar panel is pressed on the side, opposite to the supporting legs, of the pressing block body, the supporting legs abut against the clamping blocks. In addition, the pres
