What is BIPV ? BIPV or Building Integrated Photo Voltaic, as the name suggests deals with integrating the Solar Photo Voltaic panels into building design. The can be used to replace proposed glazing areas without affecting the contemporary aesthetics of steel & glass or fixed on South façade as building cladding.
BIPV benefits:
•PV as part of building support structure
• Reduced Cost
• On-site generation of electricity
• Architecturally elegant
•Highly visible public expression

Photovoltaic's into facades
Ventilated Cladding facade / Cold Facade
•Profiles or brackets are mounted on the
main bearing wall. Cassettes or panels are
attached using cladding profiles rails and
hook on system.
•Easy wiring, the wires are running behind
the modules. Generally back junction boxes.
Somewhat back ventilation.
BIPV Mounting options
BIPV Mounting options : Sun screening components
Example of fixed sunscreens over the windows.

Mounting Systems
Structural sealant glazing (SSG)
• With structural sealant glazing facades, the
solar modules are fixed in place on a metal
frame by means of circumferential load-
transferring bonds.
• This produces facades with a homogeneous
and smooth appearance.
• Furthermore, SSG facades have no external
protruding parts, which means that shading
and dirt traps are avoided.

•Aluminum mullions and
transoms profiles system.

Reduced Effects of Shading
If the performance of one PV-
module drops, due to shading,
module mismatching, or snow or
dirt on modules for example, the
modules in the same string are
affected negatively. Through the
individual connection in PV-systems
using micro-inverters the PV
modules work independently, each
at their maximum performance.

Area required = 10m2/kw
Possible BIPV areas available include.
1. South façade Wall Area= 1000 sqm ( 100 KW
system)
2. Spandrel wall areas = 500 sqm ( 50 Kw system)
3. Pergola at Roof = 75 Sqm ( 8 Kw System)
4. Entrance Canopy= 75 Sqm ( 8 Kw System)

Lifecycle benefits
BIPV systems also provide other benefits compared to
retrofitted systems:
• Additional energy savings. BIPV systems can
provide day lighting, shading, and increased
rooftop insulation. These benefits reduce lighting
and cooling requirements.
• Public relations and education. Because BIPV
system are integrated into a building they are
more visible from the street, while many
retrofitted systems are hidden on rooftops. Thus
BIPV systems can have a high profile, increasing
opportunities for education and marketing.
• Lower maintenance. Some BIPV systems can
increase the life of the roof.
