How much does a sonnenBatterie cost?

As of July 2017, electricity wholesale prices have resulted in yet another power increase for households and business across NSW. Consumers will pay an additional 20% increase for the same level of usage compared to previously. The average consumer will now pay an extra $319 per year for the same existing service.

The sonnenBatterie eco 8 is a solution to rising costs and will save you substantial money in the short term, and massive savings long term.

The largest contributing factor to the price of the sonnenBatterie is the quality of product. The sonnenBatterie is a premium top of the line battery with industry leading features including;  monitoring software which requires no learning to use and enhances the consumers experience with the ability for incredible levels of autonomy.

For a brief comparison, look to a similarly placed product; Tesla’s Powerwall 2 which has a capacity of 13.6kWh standard, and retails between $12,000-13,000AUD fully installed. sonnenBatterie differentiates through high flexibility, offering an extensive range of options between 2kWh-16kWh capacities (with the ability to upgrade in 2kWh steps down the track). Determining a definitive price for such an extensive range is hence quite difficult, especially when factoring in the size of your system, future proofing and rising electricity costs.

How much does a sonnenBatterie cost will depend on many factors including;

  1. The correct size battery your house requires (2kWh-16kWh). A battery with a smaller capacity will cost more per kWh than a larger battery relative as the larger the battery the less you pay per kWh for storage capacity.
  2. Whether you are retrofitting or installing with a new solar system.
  3. Whether you choose to be part of the sonnenFlat community
  4. Your own PV production output and personal consumption (running costs)

Your sonnenBatterie and PV system should cover you for approximately 70-80% of your power requirements. The table below illustrates some savings a consumer would expect to see running a sonnenBatterie with the appropriately sized PV system.

Solar battery technology has reached a stage where the payback period makes the sonnenBatterie an economically viable option. sonnen’s technology is both proven and reliable with an industry leading 10-year or 10,000 cycle warranty.

The considerations above did not factor in sonnenFlat which will reduce the ongoing running cost of electricity to $0 after one small annual fee is paid. To understand the enormity of this proposition, look at your last 4 electricity bills and replace that figure with an absolute maximum of $600! (maximum yearly sonnenFlat fee with the highest tier package – see below for details).
