Renovations with SUNSTYLE®

Two birds with one stone.

SUNSTYLE® is suitable for energy-efficient renovations of all roofs, replacing conventional roofing materials (roof tiles, sheet metal, Eternit). The SUNSTYLE® solar roof is not only a long-lasting roof, it also generates energy, ensuring that you achieve your targets for energy-efficient renovation. SUNSTYLE® can be combined perfectly with a heat pump or battery storage. This allows you to cut back on expensive electricity procured from the grid, which in turn has a positive effect on the profitability of the solar installation. Complete integration of the solar roof into the property also increases its aesthetic value.


An interview with farmer Hanspeter Knüsel from Hünenberg.

The barn is located in a protected visual environment. Thanks to meticulous integration of the solar roof into the roof surface, the Swiss historic preservation authorities gave the green light for the renovation.

Solar roof with an area of 600 m2, a capacity of 90 kWp and an annual output of about 90,000 kWh.

SUNSTYLE AG: Mr Knüsel, how did you come to learn about our solar roof?
MR KNÜSEL: At a trade fair. I knew right away that this was the roof for me. I always look at things with a practical eye. With this roof, I was persuaded by how the solar tiles overlap, that it doesn’t require an aluminium construction and that it consists of 6 mm safety glass. So I thought to myself, if a craftsman can stand on it, then it can also withstand the weather. It was also clear to me from the outset that only a roof-integrated installation would do for the barn.

SUNSTYLE AG: Does it produce as much energy as was projected?
MR KNÜSEL: The projected mean values have been exceeded.

SUNSTYLE AG: Would you renovate your roof today with SUNSTYLE®?
MR KNÜSEL: Yes, I have only praise for the beautiful roof. I often talk with pedestrians or bikers about it because they aren’t sure if it’s actually a solar roof as it fits so well into the surroundings. And of course the costs and benefits have to be in balance.

SUNSTYLE AG: Thank you for the interview and the good collaboration.

With its fish-scale pattern, the SUNSTYLE® solar roof is reminiscent of the centuries-old slate roof.
Our aim is to ensure that appearance of the roofscape is maintained. The traditional slate and shingle roofs in the Alpine region inspired the design of the diamond-shaped pattern. This installation principle guarantees optimal water-tightness and stability of the roof. The installation pattern and the seamless adaptation to the individual roof shape create a harmonious structure. In addition, the new solar tiles in brick red and slate grey are an excellent match for roofs clad with brown-red clay tiles and grey fibre cement tiles. The SUNSTYLE® solar roof has an extremely low construction height and can be integrated stylishly into any building.


Expectations of the energy performance of buildings will continue to increase. At the same time, we want to move away from fossil fuels and nuclear energy, and towards renewable energy sources. A fully integrated solar roof that converts clean and unlimited solar energy into electrical energy stays takes this trend into account. The SUNSTYLE® solar roof connects the two objectives in a harmonious manner: first, as a high quality construction element, it offers sustainable weather protection; and, second, it enables efficient electricity production over the entire roof surface.

Protected buildings

The SUNSTYLE® solar roof is ideal for energy-efficient renovations of protected buildings. With its homogeneous structure, it can be integrated unobtrusively into the building stock. The diamond-shaped solar tiles are similar to historic slate roofs, allowing SUNSTYLE® to contribute to the preservation of the landscape.
