There are over 84,000 photovoltaic plants in Switzerland. The photovoltaic modules are frequently mounted on roofs and at a defined angle, ensuring optimum energy yields. These mounted modules are known as BAPVs (building-attached photovoltaics) and are used solely to convert sunlight into electricity.
By contrast, photovoltaic (PV) elements can also be integrated in sections of buildings – e.g. on roofs or in façades. In addition to producing electricity, such so-called building-integrated photovoltaics offer additional benefits. The modules are design elements of the buildings and can be used, for example, for thermal and sound insulation or to deflect light.
