About us

30 years sustainably designed & sustainably made

30 years of true sustainability

Ecological, economical and social

We at Fronius Solar Energy have understood sustainability holistically for 30 years, and we are acting in the interest of future generations. This is why we attach utmost importance to all aspects of sustainability.

Since day one, we have combined innovation and efficiency to develop products and solutions that are helping create a livable future based on 100% renewable energy.

Fronius Solar Energy has always stood for sustainability, and we are enriching the lives of private and commercial customers alike with solar energy – in line with our motto "Energize your life".

Sustainably designed, sustainably made

In line with our maxim “Sustainably designed, sustainably made”, our products are not only created in an especially resource-friendly way but are also designed for superior durability and reparability. So we attach great importance to the conscious use of resources – be it product materials, the means of production, or employees.

We use recycled and recyclable materials whenever possible. In production design, we make sure that components require little space and resources and can be easily replaced, if necessary. This is confirmed by our life cycle analyses, which have been audited by the renowned Fraunhofer Institute for Reliability and Microintegration IZM.

» For us, sustainability is neither a trend nor an issue - but has always been firmly anchored in our thoughts and actions. Out of conviction, out of responsibility and because, as a pioneer in solar energy, we know how to shape a future for everyone based on 100% renewable energy. «
