sonnenFlat – Never pay an electricity bill again!

Solaray and sonnen

Free electricity with sonnenFlat – never pay an electricity bill again.

sonnenFlat is a new way for consumers to pay $0 ongoing costs for their electricity, once and for all severing their reliance on energy retailers for electricity. This means no longer paying for energy at night (when prices are their highest) when you combine your PV system and sonnenBatterie with the sonnenFlat community.

To be clear, this exciting opportunity means that customers with a sonnenBatterie can sign up to sonnenFlat and only pay one flat pre-determined fee for all their yearly electricity requirements (see the table further below for details)

sonnenFlat is an invitation to a renewable energy community

sonnenFlat is an invitation to a self-sufficient energy driven community. Instead of paying for electricity from an energy retailer such as AGL or Origin (who generate costly carbon laden emission fuelled energy through non-renewables) you say goodbye and join the new sonnenFlat network. The network operates as a free exchange of power between all customers and is managed entirely by sonnen behind the scenes, with no disruption to your energy supply.

Each customer who signs up contributes towards the daily exchange of power through their home energy generation.  sonnen provide free 


electricity by leveraging the network. To understand how this works in practice imagine sonnen as a central battery. sonnen charges this battery by collecting small incremental charges from each individual sonnenBatterie in the network. sonnen then distribute this stored energy to customers who could not generate enough power for their individual daily needs.

As a part of the ecosystem you become entirely self-sufficient through your contribution to the community.
