This year, Lausanne-based company Groux Arts Graphiques SA celebrates 70 years of printing excellence. Demonstrating a steadfast commitment to sustainability, the company has successfully achieved its ambitious goal of becoming climate neutral.
By installing solar panels and adopting innovative, efficient measures, Groux Arts Graphiques SA continues to reduce its environmental impact and establish itself as an ecological leader in the printing sector. As a recognised expert in French-speaking Switzerland’s printing industry, the company demonstrates a strong, committed environmental vision.
In line with its mission to minimise environmental impact, Groux Arts Graphiques has implemented several eco-responsible practices that underline its dedication to sustainability.
“Everything was installed right first time. No subsequent modifications were needed, which demonstrates the high quality of Younergy’s work.”

Managing Director of Groux Arts Graphiques
One of the cornerstones of Groux Arts Graphiques’ sustainability initiatives was the transition to solar energy. Recognising the environmental and economic benefits of renewable energy, they decided to install solar panels across their entire roof. This ambitious project highlights their commitment to reducing their carbon footprint and promoting sustainable practices within their industry. Comprising 210 solar panels, operational since May 2022 and covering 410 m², the installation generates around 96,000 kWh per year.
The five-month project ran smoothly, reflecting the expertise and professionalism of the Younergy teams. Currently, 65% of the electricity used by the company’s printing presses is generated by solar panels, significantly reducing their electricity costs.

According to Managing Director Mr Ducommun, the installation is expected to pay for itself within three years. By switching to solar energy, the Lausanne print house is not only reducing its environmental impact, but also setting a benchmark for sustainability across the printing industry in French-speaking Switzerland.
This strategic, visionary decision underscores its commitment to a greener planet and a more sustainable future for generations to come.
“From a technical perspective, we had to pay particular attention to the roof orientations and adapt the mounting systems accordingly, as well as to partial shading, which was mitigated by optimisers on the affected areas.”
Manuel Burneo
CEO of Younergy
This project presented technical challenges requiring a more sophisticated engineering approach. Faced with a metal roof and two flat roofs, a bespoke design was implemented to best adapt the mounting structures.
Due to shaded areas on the roofs, partial optimisers were incorporated to maximise energy efficiency. This solution mitigated the impact of shading and optimised electricity generation.
Connecting the solar panels installed across the various roofs correctly was crucial. Particular attention was paid to system connection and integration to ensure optimum performance and consistent energy generation.
This project illustrates our ability to tackle complex challenges and deliver tailored solutions that meet the specific needs of our B2B clients.
