sonnenFlat is a unique energy package for sonnenBatterie owners which allows customers to receive a guaranteed
annual allowance of energy for a fixed low monthly fee (starting at $42). With sonnenFlat, you can control your energy bills against rising energy prices.
In exchange for sonnen basically paying your electricity bills for you, you give sonnen access to your battery for helping with grid stabilisation services. For example, if there’s lots of power being exported into the grid from solar systems around the area, grid operators (not retailers) can at the click of a button, push some of that excess power into customers partaking in sonnenFlat whose batteries have spare capacity. In a nutshell, sonnen is able to provide free electricity by leveraging the sonnenFlat network.
There are three sonnenFlat packages available in Australia. Your annual flat fee will depend on which tier you fit. Each package requires a minimum solar and battery system size, see the table below.
Joining sonnen Flat is like having a mobile phone plan, with the monthly administration costs of the deal being only $42, $52 or $62 per month. Imagine paying only $504 a year for power!
sonnenFlat is the way that Aussie homeowners will be able to take back the power from the energy retailers who continue to increase prices year after year.
Natural Solar customer Stephen Fenech signed up to the
sonnenFlat energy tariff scheme in late 2017 when he invested
in a sonnenBatterie system. Since then, he has been receiving
$0 power bills, which has saved him over $2,500 for the year.
And with the ever-rising energy prices in Australia, this saving is
only going to get bigger.
Stephen has taken the cost of energy into his own hands and so
can you!
Natural Solar is selling packages to enable owners to be eligible for a sonnenFlat Tier and are selling all sizes of the sonnenBatterie, both with and without solar panels. Whatever your needs, we can supply it and install it!
For those who do not already have a solar system, getting it installed at the same time as your battery is both a cost-effective and efficient way of getting your system up and running at the lowest cost (bundle pricing, one installation team, etc.).
For those that do already have a solar system, you will get the most out of your system when you are able to take part in the sonnenFlat system, so if you already have an appropriately sized solar system, fantastic! If you don’t, we can add additional solar panels or replace your current panels with much more efficient panels.

and sonnenFlat to Sunrise
sonnenFlat is currently available in NSW, QLD (Energex region), SA,
ACT and TAS, with other states and regions, such as Victoria, to be introduced soon.
These costs are based on the SA Power network in Adelaide but prices may vary depending on your circumstances. This comparison assumes a general energy usage of 4000kWh/year for a residential customer on Energy Locals Time of Use Tariff – (TOU – Peak, Off-Peak & Solar Sponge).
The reference price is set by the Australian Energy Regulator (AER) for a financial year in relation to electricity supply to residential customers in the distribution region and is based on an assumed annual usage amount. Any difference between the reference price and the unconditional price of a plan is expressed as a percentage more or less than the reference price. The terms of any conditional discounts are shown, along with any further difference between the reference price and the discount applied if a condition is met, expressed as a percentage more or less than the reference price.
