BIPV (Building-Integrated Photovoltaic) System

BIPV refers to solar power systems where photovoltaic modules are integrated directly into the building's structure, such as on exterior walls, windows, or roofs, instead of being added as a separate system on the roof. This approach generates electricity while enhancing the building's aesthetic value, serving as a power source and architectural material. (A similar system, BAPV, refers to the installation of solar modules on the external walls of a building to generate electricity.)

Wall Facades Solar modules used as exterior materials on building walls
*Curtain Walls Solar modules applied to curtain wall window sections
Windows Window Frames Solar modules applied to building window sections
Shading Solar modules applied to shading devices attached to windows
Ceiling Building Ceiling Solar modules applied to upper ceilings
Canopy Provides shading and rain protection while generating solar power
Curtain Walls : A non-structural, load-bearing exterior cladding method that surrounds the building's outer walls, providing a lightweight, modern, and economical facade construction approach.
