Solar Impulse efficient solutions

Solar Impulse

Towards a portfolio of 1000 labelled solutions

To address environmental challenges while enabling economic growth, Bertrand Piccard has launched, through the Solar Impulse Foundation, the challenge of selecting 1000 profitable solutions to protect the environment in order to convince decision-makers in governments and businesses to achieve their environmental targets and adopt more ambitious energy policies, which are necessary to pull these solutions to market.

The aim: to accelerate the transition to a carbon-free and sustainable economy.


A label focused on both the environment and profitability

The first label to assess the economic profitability of products or processes that protect the environment. The Solar Impulse Efficient Solution Label is attributed following a strict selection process performed by external independent experts. By ensuring high standards of sustainability and profitability, this internationally recognized label is considered as a recognition for innovators and as a credible marker of quality for solution seekers in business and governments, facilitating their sourcing of solutions to reach environmental commitments.


Boosting the adoption of profitable solutions to protect the environment

The Solar Impulse Foundation aims to identify clean, efficient and profitable solutions in order to accelerate their implementation and the transition to a sustainable economy. Thanks to the awarding of a label with high standards of sustainability and profitability, the Foundation can support political and economic decision-makers in their efforts to achieve their environmental targets and encourage them to adopt more ambitious energy regulations, necessary for implementation at large-scale of these solutions on the market.

A way to take the success of the first round-the-world solar flight further.

Valais excellence certified

Valais Excellence

Decades of local anchoring

We have been developing, manufacturing and testing our products in Sion (Valais region), in the heart of the Swiss Alps, ever since 1987. We therefore wanted to show that we belong to this magnificent region by joining the “Valais Excellence” label.

This certification was created to reward those Valais-based companies which stand out because of their social and environmental performance, while continuously improving their products and services.


Quality assurance for our partners

For Studer’s partners, the label is evidence that our company

  • is based in the Valais
  • holds ISO 9001 certification for quality and ISO 14001 for the environment
  • is committed to the Valais and its inhabitants

In order to be eligible, we had to meet a number of criteria relating to governance, as well as societal, environmental and human aspects. Our internal processes were analysed, in particular those involving the development of our products, our facilities and our relations with local partners.

We were really keen to have a positive influence on the Valais ecosystem, which has allowed us to develop over time.
