If you enter these details into the Solar Analytics Solar Maximiser calculator or the SunSPOT Solar and Battery Calculator, either of these will offer you some advice on optimising your energy management system and the potential savings you can make.

Meanwhile, the team at Solar Quotes have crunched the numbers and the good news is that, in Adelaide, Brisbane, Perth and Sydney, the annual savings are likely to be over $1,000 and the payback period is likely to be around 6-8 years. 

Our analysis Calculating Home Savings Under the Cheaper Home Batteries Program found that a 4-person household in Sydney or Adelaide can save around $5000 on the cost of a 10Kw battery, and can save up to $14,000 in energy costs over the 10year (warrantied) lifetime of the battery. For more details see our report -

Household batteries are expected to last 10-15 years (we don’t really know yet!) and so the deal is a sweet one in these locations. You might want to proceed more cautiously in Melbourne, Canberra and Hobart where the payback period may be more than 10 years even with the federal rebate.
