Solar Integrated Building Cells (BIPV) are photovoltaic materials used to replace traditional building materials in some building exterior parts such as roof, skylights, or facades. They are increasingly involved in the construction of new buildings as the main or additional source of electric power generation, and some older buildings have also been supplied with BIPV. One of the advantages of integrated solar energy units, unlike non-integrated systems, which are most common is that the initial cost can be reduced by reducing building materials and labor used when building part of the building where BIPV units are used. In addition, the BIPV modules are embedded in the design, they generally make a better combination and aesthetically more attractive than other different options for solar energy. These advantages make BIPV one of the fastest growing sectors in the PV industry. The past decade has opened the door to countless building revolutions that use BIPV as well as other facilities. In both new projects and renovations, BIPV proves to be energy efficient technology that is used in residential, commercial, and industrial buildings as well as institutional structures.
