Film integration

• To obtain the best possible performance and reliability, our films are simply added on top of standard

PV modules during the lamination process.

• Both glass/backsheet and glass/glass configurations are supported.
• We currently recommend the use of ETFE frontsheet protection for our film (mat or brilliant)

→ ETFE is a proven material for large architectural projects.

Your contribution for the environment?

• Lower operating temperature:
• A reduction of around 14°C was measured at the

back of the module with an outdoor temperature

• f 25°C (44 instead of 55°C)
• Compared with standard black PV modules, the

cells are operating at a lower temperature. → Reduced performance loss in warm climates → Reduced building air conditioning needs

• Limit urban heat island effects

Façades become active and beautiful

• New regulations for energy efficient building

renovations are coming worldwide

• White or light-coloured active full-building

elements that are cost effective, durable and aesthetically pleasing.

• Architects can incorporate renewable energy

into their design without compromising their aesthetic vision.

These new active facades will become an essential part of the building enveloppes in the years to come

Think about the future

Solaxess – Peter Roethlisberger, COO SÖLELMÄSSAN, 27th of November 2018

It started already !

White or colored, photovoltaics become 100% building integrated

• Former central post office administration

building in Lausanne, renovated in 2013.

• If this building had been renovated in 2018
• it would produce 132 MWh per year
• enough for 35 family homes

thanks to our technology
