Announced today sonnen, the world’s largest home battery storage manufacturing company will be opening its doors to a battery manufacturing plant in South Australia.
This will be the first plant in Australia to build and manufacture residential and commercial battery storage solutions which is a huge milestone for the Australian battery industry.
This exciting news for consumers in Australia comes following the announcement from the South Australian Government that they will offer $100M in state government subsidies for up to 40,000 households to install battery storage in their homes.
Individual grants of up to $6,000 will be available to help with the purchase of batteries.
Australian made products (sonnenBatteries) and their installers are expected to be prioritised in the rebate.
Natural Solar is the largest solar and battery installer in Australia, and an established partner of sonnen.
As the largest installer of sonnenBatteries nationally, at Natural Solar, we are able to offer our residential, commercial and developer customers the best pricing available in the market due to our purchasing power.
Our competitive home battery storage and solar pricing, coupled with the newly announced rebates will offer an unbelievable return on investment for Australian homeowners, with eligible homeowners to be able to experience high savings and, in some cases $0 electricity bills.

There are a number of tiers within the sonnenFlat program.
|sonnenFlat 8||sonnenFlat 10||sonnenFlat 12|
|Minimum Solar System Size (kWp)||5.0 kWp||7.5 kWp||10.0 kWp|
|sonnenBatterie eco 8 Size (kWh)||8kWh||10kWh||12kWh|
|Monthly Administration Fee||$30||$40||$50|
|Annual Consumption Allowance in kWh||7500||10000||12500|
The Wilsons annual household consumption is 10,000kWh. The Wilsons currently pay $0.31372/kWh (incl.GST) which leaves them with an electricity bill of $3,472 including daily supply charges.
The solar system of 7.5kWp and the sonnenBatterie eco 8.10 (10kWh, 8th Generation battery) enable them to participate in the sonnenFlat 10 tier which leaves them with a significantly reduced energy bill, as per the calculation below.
|Savings per year installing solar system, sonnenBatterie and credit from sonnenFlat||$3,472|
|sonnenFlat 10 fee per year||$480|
|Net savings per year||$2,992|
|Net savings over 10 Years (assuming prices stay at 2017 levels!)||$29,920|
The sonnenFlat concept is already in use in Germany, with about 60,000 customers taking advantage of this system.
So what’s the catch? 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.
Looking at the Germany model for sonnenFlat, it works on a number of tiers, where the owners size of the solar system and the size of their battery energy storage determines the amount of free electricity the owner is entitled to. If a customer exceeds the amount based on their tier, then the owner starts to get charged only for electricity imported from the grid (not from power generated from your solar system and power utilised from your battery) at a rate significantly lower than standard retail electricity rates.
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.
The eligibility criteria for sonnenFlat are:
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.
