Sonnen Flat

SonnenFlat is a World first and will definitely shake-up the Australian market. Choosing sonnenFlat as your electricity distributor effectively caps your electricity expenses at $42 to $62/month depending on consumption. It makes you part of a virtual solar power plant which looking into the future could be the means of selling solar power to people who don’t have solar systems but want reliable, cheaper electricity than the grid will be able to provide. This is already happening in Europe. Even if you don’t go for the sonnenFlat deal, you are purchasing a solar battery that can cycle three times a day. As a household you will be capable of producing a lot of solar generated electricity for your own use or to send to the grid.

minimal energy production,
high energy needs.

At sunrise the solar panels Melbourne 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.


highest energy production,
low energy needs.

In the daytime the solar panels’ energy generation is at it’s peak. But since nobody is home the energy consumption is very low so that most of the generated energy is stored in the sonnenBatterie.


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 cover the energy needs with the energy produced in the daytime.
