Self-consumption with battery

A 6.6 kW solar system in Newcastle generates approximately 28.4 kWh per day based on the local average of 4.3 kWh/kW/day. Without a battery, most households self-consume only about 35% of that generation because they are at work during peak solar hours. The remaining 65% gets exported at low feed-in rates of 5 to 8 cents per kWh.

Adding a home battery increases self-consumption to around 80%. Instead of exporting surplus solar at 5c/kWh, you store it and use it during expensive peak hours at 30c+ per kWh. That shift is worth an estimated $1,400 per year in additional electricity bill savings for a Newcastle household.
