BiPV market drivers
Building Image
& Value
• Tenants seek stable operational costs and
pay premium for low energy costs
• Energy Consumption Certifications like
LEED or BREAM become more relevant
• Integrated systems provide visible green
image and attract attention
• Unlike traditional systems BiPV increases
value of the building skin (refurbishment)
Incentives
• Feed in tariffs for generated energy
• Bonus for direct consumption
• Tax credits for BiPV systems
• Accelerated depreciations
• BiPV bonus on tax or feed in tariffs
Regulative Environment
• Today buildings account for majority of CO2
emissions
• Regulations on total building energy
consumption drive need for renewable
energy generation (Germany)
• Strict obligations to install renewable
systems like PV

Conflict of interests
Architects requirements
- building approved components
- project-specific dimensions
- individual optical characteristics
- various integration options (mechanical, electrical)
- support during planning and tendering
- solutions within budget
PV module manufacturer requirements
- efficiency increase
- increased productivity via standardization
- no product variation
- cost reduction of material selection

• Size and Shape
• Glass-types (e.g., coating)
• Glass thickness and colors
• Flexible material (bendable,
light weight)
Frame / Frameless Options
• Size, material, color
• Adaptable to building
requirements
SuperCell Options
• Size and Shape
• Performances (U/I)
• Flexible material (bendable, light
weight)

Shading Behaviour
Leistung
• High system stability in case of shading
(vertical and horizontal)
• Minimum losses due to shading and mismatch

Verschattung
16
Flexible in size and shapes
50 mm <-> 4000 mm
in mm steps
Size: sizes can be flexibly defined by variation in length, hight and number of supercells
200 mm <-> 1200 mm
in mm steps
Shape: position and lenght of supercells allow free shapes
