The employee initiative "100 ideas to tackle climate change" was launched at Comet in 2022. Now, another one of those ideas has become reality: the installation of a solar power system. With this step, we're not only reducing our carbon footprint, but also turning employee-driven ideas into lasting impact. It's a concrete move toward a more sustainable future - and a reminder that progress often starts with a single idea.
We are pleased to announce that our Flamatt headquarter is now producing green energy, thanks to the successful connection of our photovoltaic (PV) system to the electricity grid. This milestone brings us one step closer to reducing our carbon footprint.

To ensure the profitability of our solar energy operation, we focused on two crucial factors: sunlight exposure and self-consumption. By analyzing a solar cadaster, we identified the optimal rooftop surface for our PV system installation. The more sunlight we collect, the more energy we produce. Equally important is maximizing our self-consumption. The higher our self-consumption rate, the less energy we need to sell at lower prices to the distribution grid operator. We are proud to achieve a 95% self-consumption rate with our current setup.
Our PV system uses state-of-the-art technology to maximize efficiency. The system's inverters convert solar energy into usable electricity, significantly reducing our reliance on non-renewable energy sources.
The installation process began in the summer of 2024. We removed the existing roof covering and installed solar panels, positioning half to face west and the other half east. This orientation ensures maximum efficiency through optimal solar exposure. The panels were then connected to inverters and finally to the PVA sub-distribution board, which feeds the generated energy into the building's electrical grid.
We firmly believe that our technologies can contribute to a better, fairer and more sustainable world. To this end, we will continue to focus on developing solutions that add value for our customers while protecting the environment and honoring the needs of society. We are proud that sustainability is well on track to become an integral part of our corporate culture.

This past weekend, it was finally time: we, the apprentices at Comet, lined up at the starting line of the 6h de Fribourg - a national race held as part of the Hydrogen Grand Prix (H2GP). After weeks of designing, testing, and teamwork, the big moment had arrived. And while the race turned out very differently than we'd hoped, it became an experience we won't forget anytime soon.

At Comet, we believe progress starts with curiosity - and few frontiers spark it like space. That's why we're partnering with Project HERMES as a sponsor - supporting the student team at ARIS to build and launch a bi-liquid propulsion rocket at the European Rocketry Challenge (EuRoC) in 2025. If successful, it will be the first Swiss rocket of its kind to reach an altitude of 8000 m - a major milestone for student aerospace in Switzerland. From cryogenic propellants to guided recovery, HERMES is a showcase of what happens when curiosity meets collaboration. Just like in our own work, their success depends on precision, teamwork, and a drive to go beyond - values we share as they reach for the skies.
