About Sonnen
One of the most reputable brands in clean energy in the world is the source of the Sonnen Battery. In the German village of Wildpoldsried, Sonnen was founded in 2010 by Christoph Ostermann and Torsten Stiefenhofer with the audacious goal of promoting decentralised renewable energy and removing fossil fuels from the planet.
This dream came true in their hometown of Wildpoldsried, where Sonnen was instrumental in converting the entire community to run entirely on renewable energy.
The multinational energy corporation Shell purchased all of Sonnen’s shares in 2019. Even though it is now a fully owned subsidiary of Shell, Sonnen has maintained its focus on sustainable energy solutions, independence in innovation, and brand name.
