Join a unique energy community with more than a quarter million members globally, who power their homes using solar batteries.

The number of people using a sonnen solar battery is growing every day. We call them the sonnenCommunity. Yet, we are much more than just "users". We are visionaries who share a common goal: clean, reliable, and affordable energy for all.

How does a solar battery work?

A solar battery makes it possible for you to enjoy the sun's energy at any time of day. Our technology optimises your energy consumption, ensuring you use your self-generated power precisely when you need it the most. No more relying on the grid or purchasing energy at a higher rate in the early morning or evenings. Instead, your solar battery stores any excess energy, allowing you to enjoy a refreshing evening shower or cook your dinner using clean energy captured during the day. Embrace a sustainable life and maximise your energy independence with sonnenBatterie.
