Solar Storage Community Platform

Combining solar polar, advanced battery technology, and a digital community, sonnen enables the delivery, storage, use, and trade of clean and affordable energy.

The sonnenBatterie is a smart residential energy storage system incorporating a ready-to-install lithium-ion battery to be used for up to 10,000 charge cycles. The battery is charged using electricity from solar panels, enabling a household to cover the biggest part of its electricity needs with emissions-free solar energy. SonnenBatterie works in tandem with sonnenCommunity, an online network of sonnenBatterie owners connected by a central software that links and monitors all members. Members can share their surplus self-produced electricity with others in the sonnenCommunity who cannot produce enough electricity due to bad weather, making the community independent from conventional energy suppliers.
In February 2016, sonnen reached 10,000 customers. The pricing of a fully integrated sonnenBatterie starts at $3,599 including VAT for members of the sonnenCommunity. After acquisition costs, sonnen claims the solution can cut electricity expenses of a typical household by up to 75% within a year.

Relevance of solution

Clean and affordable energy is one of the greatest challenges of our time. By deploying residential battery storage systems to store energy from the sun, the sonnenBatterie and the sonnen-Community are paving the way for a transition from centralized power plants running on fossil fuels to cheap renewable energy.

Triple Bottom Line


With more than 10,000 customers, sonnen saves hundreds of thousands of MWh of fossil fuel-based emissions by using clean, emissions-free electricity.


SonnenCommunity enables members to become independent from conventional energy providers.


Due to the high level of self-consumption, sonnen users are less vulnerable to rising energy prices.
