«The production of renewable and sustainable energy is close to our hearts.»
André Posnansky, CEO and Owner SUNSTYLE LTD

Our need for living space and mobility is increasing, as is our global energy demand. The combustion of oil, gas and coal as non-renewable energy sources and the resulting release of CO2 into the atmosphere are reasons for global climate change. The generation of electricity from uranium in nuclear power plants is also causing problems. The use of renewable energy sources such as the sun reduces dependence on non-renewable energy sources.

The energy optimization of buildings plays an important role. Energy-efficient buildings not only consume less energy but can also be used for energy generation. The use of roof surfaces and facades to generate solar power is an obvious solution. The aesthetics of our roofs is also an important consideration. Solar energy generation should not conflict with attractive roof landscapes and historical townscapes.

With the SUNSTYLE® solar roof we have developed a versatile solution that is both a roofing material and a power plant. Thanks to the new color technology, SUNSTYLE® photovoltaic shingles can be produced in a variety of colors and surface structures. The roof as an architectural design element makes optimum use of the built-up areas for the production of valuable solar power.

For more than 10 years, roofs with SUNSTYLE® power-generating shingles have been in use to the complete satisfaction of international clients. New roofs are constantly being added and they will produce electricity for the coming decades. With these SUNSTYLE® systems we make our contributions to a sustainable power supply.

Renovation with SUNSTYLE tiles wins Solar Prize.

This former detached house dating from the 1960s was converted into two semi-detached residences and renovated to become energy efficient. Despite a higher number of consumers and a larger energy reference area, the building’s energy requirements were reduced by 61%. In addition, thanks to the PV installations installed on the south side of the roof by Ackermann AG, it was possible to build an EnergyPlus construction at a low cost. The project was awarded the HEV Special Solar Prize in 2019.

The Brunni cable cars are carbon neutral.

The Restaurant Ristis mountain lodge has been completely covered in SUNSTYLE® solar tiles. More power is now being produced than the restaurant requires annually. By replacing oil heating with a wood pellet heating system and implementing further measures, which are supplemented by the myclimate climate protection initiative to compensate for unavoidable carbon emissions, the Brunni-Bahnen Engelberg AG became the first carbon-neutral cable car company in Switzerland in May 2018.

Church unites tradition and future.

Sarpsborg, the third oldest town in Norway and today an industrial town, has a rich cultural heritage, which also includes the town church from 1862. At the beginning of 2019, the roof of the neo-Gothic church was renovated with SUNSTYLE® solar shingles. The church in the centre thus becomes a symbol of the interplay of tradition and future.
