According to the installation system of solar Photovoltaic cells, it can be divided into non-integrated installation system (BAPV) and Integrated installation system (BIPV).
BAPV refers to the solar photovoltaic system attached to the building, which is also called “installation” solar photovoltaic building. Its main function is to generate electricity, without conflict with the function of the building, and without damaging or weakening the function of the original building.
BIPV refers to the solar photovoltaic power generation system that is designed, constructed and installed at the same time with buildings and forms a perfect combination with buildings. It is also known as “construction” and “building material” solar photovoltaic buildings. As a part of the external structure of the building, it not only has the function of generating electricity, but also has the function of building components and building materials. It can even improve the beauty of the building and form a perfect unity with the building.
