Photovoltaic panels can be mounted on top of an existing façade (BAPV) or can replace the construction material itself (BIPV). Informative overview.
BAPV
Solar panels installed on top of an existing façade or roof. They do not replace the construction material but are attached to it using mounting systems.
BIPV
Solar panels that become part of the building's structure and replace traditional materials such as glass, stone or metal cladding.
Generic schema
Schematic illustration without values; the actual configuration depends on the project.
| Parameter | BAPV | BIPV |
|---|---|---|
| Integration type | Mounted on top of existing façade | Integrated as a structural element |
| Construction role | Adds a power-generating system | Façade material and generator in one |
| Installation | Fast retrofit | During construction or renovation |
| Cost | Moderate investment, quick ROI | Higher initial cost, long-term benefits |
| Aesthetic appearance | Add-on system | Full aesthetic integration |
| Thermal & acoustic insulation | Moderate | Excellent |
| Customization | Available in various colours and dimensions | Custom shape, colour and transparency |
General comparison; exact values depend on the project.
Façade solutions can be made to order in different colours, textures and sizes, for rainscreen, curtain-wall and prefabricated systems. Availability and terms are agreed per project.
