Building-Integrated Photovoltaic Systems ( BIPV ) technology involves the incorporation of solar panels as an integral part of the architecture, rather than as an accessory. In addition to fulfilling structural and aesthetic functions, the building components generate energy. BIPVs are integrated into roofs, façades, windows and canopies.
Advantages of integrating photovoltaic systems into buildings
High flexibility to adapt to the design of the architecture, or an aesthetically and functionally attractive option, and their contribution to the sustainability of the building, are clear advantages of BIPVs. In fact, photovoltaic panels are available that mimic traditional building materials, such as tiles, glass or metal, or feature multiple textures, colours, geometries and dimensions. In this way, BIPVs do away with the limitations of the rectangular shape of conventional solar panels.
Energy efficiency of BIPVs
But BIPVs not only improve the aesthetics of a building, they also optimise its energy performance. These systems act as thermal insulators or replace conventional building materials, giving architects the opportunity to innovate without sacrificing energy efficiency.

The challenge of building-integrated photovoltaic systems
Although technological developments in the field of solar panels have made it easier to assimilate them with various building materials, their high initial cost is a drawback. In addition, the task requires complex planning and careful design, as well as extensive technical studies of electrical integration.
Maintenance of Building Integrated Photovoltaic (BIPV) systems
The maintenance of BIPVs is similar in many respects to that of conventional solar panels. It should be regular maintenance to ensure efficiency and prolong their lifetime. However, due to their direct incorporation into the building, aspects such as access to them and preserving the integrity of the building must be considered.
