Why Choose sonnen?
Revolutionising the energy system
Imagine a world where energy is yours.
Where community is the driving force to create positive change. Where clean technologies improve the lives of as many people as possible.
This is the world sonnen is creating for you.
Our endeavours are based on the vision of two pioneers, Christoph Ostermann and Torsten Stiefenhofer. They challenged the status quo and wanted to create a world where energy is clean and affordable for all people. In 2010, they found the perfect place to start sonnen and work on that vision: A small village in Bavaria, Germany, famous for its deep commitment to renewable energy and accelerating the energy transition.
We have been tirelessly working towards developing the best, most innovative energy solutions ever since.
Starting with individual systems that have evolved into a global network, we connect people and technologies every single day. By doing so, we have built a community with thousands of innovators and change-makers: the sonnenCommunity. This community serves not only our customers, but everyone on this planet.
