Preferably, the waterproof part is in the shape of a curved umbrella. In the present invention, the umbrella shape of the curved surface can be a symmetrical structure, and the symmetrical waterproof part of the curved surface can prevent the direct intrusion of rainwater. When the photovoltaic system is installed on the roof with a certain slope, the rainwater can naturally flow down along the umbrella shape of the curved surface, thereby waterproofing effect.

Preferably, both ends of the waterproof part extend to the surfaces of the photovoltaic modules on both sides. Prevents rainwater from entering the joint interior of the photovoltaic module.

Preferably, both the male frame and the female frame are made of metal.

The present invention also provides a building roof photovoltaic system, which includes a plurality of photovoltaic components, and the plurality of photovoltaic components are connected through the connection components of the above photovoltaic components.

Compared with the prior art, the beneficial effects of the present invention are reflected in:

(1) The present invention realizes the snap-fit installation of the left and right adjacent photovoltaic modules by adopting specially designed metal components of male and female pairing, and the upper and lower installation can adopt the stacked installation of the lower edge of the traditional building material pressing the upper edge. In the present invention, the female frame is the upper The symmetrical curved umbrella structure realizes the rainproof function of adjacent joints, and the symmetrical curved umbrella shape can achieve the effect of corrugated beauty.

(2) If a small amount of rainwater enters in the present invention, the rainwater can be blocked by the first limit rib and the second limit rib. If the rainfall is large, some rainwater will pass through the first limit rib and the second limit rib. Limiting the sidewall and entering the slot on the male frame, the slot can be used as a kind of water collection tank, rainwater flows along the slot, and can also play the role of rainwater diversion, so as to discharge accumulated water in time.
