  • Patent number: 11967919
    Abstract: A photovoltaic building material, which can safely generate electric power with solar power energy is disclosed. The photovoltaic building material can be used as building material, and can be directly installed on the fixed part of the building, such as roof, wall or decoration materials on the surface of building. The photovoltaic building material is accord with the architectural requirements of waterproof, fireproof, load-carrying ability, durability and heat-insulation. When this invention is installed on the roof, the automatic spraying device can be set up on the height of ridge, which realizes the functions of roof cleaning and cooling down by the automatic water spraying. Also, with the auxiliary device, this invention can intensify the ability to withstand strong winds for roof, and can ensure safety in the typhoon/hurricane area.
