Climacy has put Switzerland's most efficient integrated solar roof into operation

At the Construction Professionals Forum, which this year focuses on solar energy, Climacy presents its revolutionary solution for renovating your roof: SMART SOLAR ROOF.

This innovative concept combines energy conservation and renewable energy production for a greener home and significant savings.

Aesthetic and efficient photovoltaics! Climacy has put Switzerland's most efficient integrated solar roof into operation in Villars-Ste-Croix

Switzerland, known for its commitment to sustainability and innovation, has reached a new milestone in the pursuit of energy independence and environmental responsibility. The latest legislative proposal stipulates that from January 2024 all new buildings with more than 300 m² must be equipped with solar systems. This direction requires significant efforts to integrate photovoltaics into all types of buildings.

Improving current solar solutions

The most common and well-known practice is the installation of solar panels on existing roofs. But this solution can be improved: on the one hand, installing solar panels on outdated and poorly insulated buildings is unwise, while 60% of buildings in Switzerland that are over 40 years old need a roof in the short or medium term renovation. On the other hand, these panels usually only cover part of the roof and integration is difficult and in some cases even unsightly.

Climacy's vision: maximizing efficiency and preserving the harmony of buildings, the example of Villars-Sainte-Croix

For its latest achievement, Climacy installed the most efficient and aesthetic residential solar roof in Switzerland in Villars-Ste-Croix. Its fastening system and its frameless tile panels, patented technologies developed in Switzerland, made it possible to replace the roof tiles and insulate the house, while creating a uniform and aesthetic photovoltaic roof down to the centimeter and reducing heating consumption. With the best photovoltaic energy efficiency on the Swiss market – 225 W/m2 – the roof then becomes a real electricity production system.

Climacy solar roofs are characterized by their sophisticated design and aesthetics. This is a significant advance in harmonizing photovoltaic panels with modern architecture while ensuring superior energy efficiency.

Towards energy-positive architecture

The Climacy Initiative reflects a growing movement towards positive energy buildings. The company relies on global know-how to achieve energy autonomy: “Our integrated solar roof is more than a product, it is a commitment to a sustainable future.” With every installation we come closer to our vision of buildings that produce more energy, than they consume, thus starting the virtuous cycle of decarbonization. »

Prospects and future developments

The global building-integrated photovoltaics market, estimated at $19.82 billion in 2022, is booming at a compound annual growth rate (CAGR) of 21.0% from 2023 to 2030.

To secure a privileged place in this market, Climacy wants to take a new step and introduce a revolutionary photovoltaic solution. This technological advance integrates state-of-the-art thermal insulation and sealing elements directly into photovoltaic modules, setting a new standard in integrated solar energy. This makes roof renovation faster and cheaper and therefore more profitable.

In collaboration with CSEM and EPFL, Climacy's research and development efforts have resulted in the receipt of a significant European grant of CHF 2.2 million to support the development of this next generation of solar roof solutions. This grant is part of the “Increase” project, which aims to expand the possibilities for integrating photovoltaic solar energy with 21 partners and a budget of 10 million euros over 54 months.

For this, Climacy SA thanks the continued support of the European Union, SERI and the support of SPEI.
