The peak period for energy demand - when you will pay most for your grid electricity - runs in most states from 4.00 pm - 9.00 pm. 

If you are installing a battery to lower your energy bill, your first aim should be to cover your electricity demand during those hours for most of the year. As a rule of thumb, that might require enough storage to cover about one third of your average daily use.

You might decide to get a bigger battery system than you need knowing you only have access to the Cheaper Home Battery rebate once and the very best subsidy rate is right now! The more battery storage you have the better you are covered for those cloudy and rainy days when your solar production shrinks.

If you are looking to ‘right size’ your home energy system, you might like to start your investigations by trying out the SunSPOT Solar and Battery Calculator, an easy to use and free to all, online energy calculator funded by the Australian Government.  It will ask you about your existing energy consumption to consider what combination of solar and battery storage will work best for you.
