The sonnen Group

The sonnen Group The sonnen group is the worldwide market leader for energy storage and the operator of the largest energy sharing platform. As one of the fastest growing companies in Germany and Europe, sonnen has received numerous international awards for its technology. In a ranking of the “Top 50 Smartest Companies 2016” by the Massachusetts Institute of Technology (MIT), sonnen was listed alongside Amazon, Facebook and Tesla.

In 2010 Christoph Ostermann and Torsten Stiefenhofer founded the sonnen GmbH. The company's goal from the beginning was to provide all people with clean and affordable energy. Until today this is the vision of sonnen, which the company is implementing step by step and is now pursuing worldwide.

In addition to its headquarters in Wildpoldsried in the Allgäu region of Bavaria and its location in Berlin, sonnen has international offices in Italy, Great Britain, the U.S. and Australia. sonnen also has three production sites in Wildpoldsried (Germany), Atlanta (USA) and Adelaide (Australia). With its core markets, sonnen is active in over 21 countries worldwide realizing a clean and decentralized energy supply from renewable energies.

The basis of this vision is the sonnenBatterie, a smart battery storage system. With the sonnenBatterie, a household can cover around 80 percent of its annual needs with self-generated, clean solar energy.

With the digital networking of the individual solar batteries, Germany's first, decentralized energy community has emerged in which storage owners can generate their own electricity and share it with others. In this way members of the sonnenCommunity can become 100% independent of a traditional provider and supply their households completely by renewable energies.

Members can also participate in the world's largest virtual power plant of thousands of networked solar batteries. The network can compensate fluctuations in the power grid in a matter of seconds by tapping into stores or releasing excess energy. This will make the electricity grid more flexible for the use of renewable energies.

Investors in the Bavarian company include the U.S. technology corporations General Electric and Shell.
