Paving the way for a future worth living
From research and development to production: Almost all of our products, solutions and digital tools are developed and produced in Europe – predominantly in Austria. So they are “Made in Austria” and “100% Made in Europe”. We firmly believe that the close proximity of everyone involved is also essential to the high product quality our customers know they can rely on.
We verify our high quality standards with tests under extreme conditions including extreme temperatures, humidity, ice, salt, dust and dirt, which our products and solutions withstand without sustaining damage.

ONE OF THE EARLIEST SOLAR PIONEERS
The future belongs to sustainability
Sustainability has been one of our primary guiding principles since our founding. Our entire portfolio is therefore produced in the most resource-conserving way possible. This applies to how we use materials as well as to how we use energy. In addition, all our products are designed for exceptional durability and excellent repairability. This is confirmed by our life cycle analyses, which have been audited by the renowned Fraunhofer Institute for Reliability and Microintegration IZM.
