Novel metal composite tile and BIPV photovoltaic system

The utility model relates to the technical field of roof photovoltaic supports, and provides a novel metal composite tile which comprises a main body and a protruding structure. The cross section of the protruding structure is in an inverted U shape, a downwards-concave limiting groove is formed in the top face of the protruding structure, and a groove opening of the limiting groove shrinks inwards to form a limiting edge. The BIPV photovoltaic system comprises the novel metal composite tile, a pressing block and a photovoltaic panel, the pressing block is arranged at the top of the protruding structure and right faces the limiting groove, the pressing block is connected with the protruding structure through a wing-shaped bolt, and the countersunk head is arranged in the limiting groove. According to the utility model, the metal tile is provided with the convex structure, and the upper surface of the metal tile is compounded with a layer of waterproof coiled material, so that not only can the waterproof requi
