The solar roof becomes part of the architecture.
An interview with the designer couple Regula Trachsel and Sascha Schär about their project: their home/office building.
New construction of a residential and business building according to the cradle-to-cradle principle, in Zweisimmen, Bern.
Solar roof with an area of 130 m2, a capacity of 14 kWp and an annual output of about 12,000 kWh.
SUNSTYLE AG: Ms Trachsel, why did you choose this solar roof?
Ms Trachsel: We came across SUNSTYLE® while researching simple and flexible PV modules. As we were planning an unusual roof shape, the connections to the eaves and barge board with SUNSTYLE® seemed very easy and inexpensive to solve.
SUNSTYLE AG: What was your first impression?
Mr Schär: At first glance, the roof just seems to be a roof and not a photovoltaic installation! We like this a lot!
SUNSTYLE AG: Which characteristics were important for you?
Mr Schär: For our home and office building, which we built according to the cradle-to-cradle principle, it was important for us to choose a product that could be dismantled and recycled easily. I see great potential in the simplicity of the system with its wood counter battens and glass modules.
SUNSTYLE AG: Your installation has been in operation since June 2014. Does it produce as much energy as was projected?
Ms Trachsel: Yes, the winter months have been a pleasant surprise! In contrast to nearby PV installations, our roof has had hardly any snow. The snow just slides off the eaves after a short time.
SUNSTYLE AG: Thank you for the interview and the good collaboration.
