Building Integrated Photovoltaics refers to photovoltaic systems integrated with an object’s building phase. It means that they are built/constructed along with an object. They are also planned together with the object. Yet, they could be built later on. A Building Integrated Photovoltaics (BIPV) system consists of integrating photovoltaics modules into the building envelope, such as the roof or the façade. By simultaneously serving as building envelope material and power generator, BIPV systems can provide savings in materials and electricity costs, reduce use of fossil fuels and emission of ozone depleting gases, and add architectural interest to the building. While the majority of BIPV systems are interfaced with the available utility grid, BIPV may also be used in stand-alone, off-grid systems.
