How it works - the solar energy storage from sonnen


How the sonnenBatterie gets you through the day

Clean energy during the daytime, in the evening and at night.

Morning: minimal energy production, high energy needs.

At sunrise the solar panels start to produce energy, though not enough to cover the morning energy needs. The sonnenBatterie will bridge the gap with the stored energy from the previous day.

Midday: highest energy production, low energy needs.

In the daytime the energy generated from the solar panels is at its peak. But if no one is home the energy consumption is low so an unused generated energy is stored in the sonnenBatterie for use later.

Evening: low energy production, high energy needs.

The highest daily energy consumption is in the evening when the solar panels produce little or no energy. The sonnenBatterie will use the energy stored during the day to cover the household energy needs in the evening.
