Solar power generation system terminal module

The invention discloses a connecting module for a solar power generation system. The module comprises a connecting box and a cable, wherein the cable is electrically connected with an electric connecting terminal in the connecting box; a fastening piece is clamped at the inserting end of the cable inserted into the connecting box; and the inserting end of the cable is fixed in the connecting box through a locking piece which is matched with the fastening piece in a detachable mode. In each embodiment of the invention, the cable is fixed in the connecting box through the fastening piece on thecable and the locking piece which is matched with the fastening piece in the detachable mode, and the electric connecting terminal is electrically connected with a bus bar of a solar panel in an elastic clamping mode, so that the cable can be freely replaced, and the bus bar can be easily split; in addition, the inside of the connecting box is not sealed by a potting adhesive, so manufacturing working hour can be shortened, and cost can be reduced.
