"Partnering with Sundust has been a great experience for our organization. As a social education institution, we want to set an example - including in the area of sustainability. Without any investment of our own, we were able to significantly reduce our carbon footprint while also benefiting from stable electricity prices. The fact that we can now cover 60% of our electricity needs with solar energy makes us proud and shows our young people that climate protection and economic activity can go hand in hand. The smooth installation and worry-free operation won us over. We couldn’t have asked for a better solution."

About us

Since our founding in 2017, we have pursued a clear goal: to make sustainable energy generation profitable for businesses and accessible to investors, thereby contributing to the energy transition.

Our approach is simple: partnering with specialized planners, developers and EPCs, we finance, install and operate systems for renewable energy generation and energy efficiency. This way, we offer property owners and businesses customized, comprehensive solutions to reduce energy and investment costs while supporting them in the transition to a carbon-neutral and efficient energy supply.

Sundust AG’s core expertise lies in the financing and operation of energy systems. Our business began with the planning, financing, and operation of industrial photovoltaic systems. This allowed us to establish the necessary processes and partnerships to offer comprehensive energy solutions today.

We firmly believe that the technologies needed to stop climate change already exist. Through comprehensive as-a-service solutions, we aim to make it as easy as possible for companies to implement these technologies—thereby not only supporting the environment but also reducing energy and investment costs for our customers.

Sundust is a member of SWISSOLAR and Switzerland Innovation.
