Description
ertex solar specializes in the production of modules for building-integrated photovoltaics, which are manufactured according to customer requirements.
For the building House Solaris in Zurich, two challenges had to be overcome. On the one hand, the modules should correspond to the architect’s colour ideas. On the other hand, the production of electricity should not be affected too much by the colouring. The result is a special photovoltaic module with a colour that was developed over the span of a few months. As front glass a special structured glass was used.
Thanks to the fully activated building envelope, the building is completely self-sufficient with the help of 1,300 photovoltaic modules in total and generates electricity beyond that. The individual solar-activated areas of the building envelope are optimally aligned so that electricity can be produced in a reasonably balanced way throughout the day and throughout the year.
In addition, scattered light is radiated onto the photovoltaic cells via the front glass used in the building envelope, which only results in yield losses of about 3-4%, although the cells are not visible to the naked eye even on closer inspection. The 47 kW PV facade system generates approximately 17,000 kWh per year, while the PV roof generates 14,809 kWh per year. The total solar yield of 31,832 kWh per year covers 47% of the total energy requirement of 68,000 kWh per year.
