Store your solar energy for use at night or during blackouts. The federal Cheaper Home Batteries rebate now uses tiered rates: around $258/kWh on the first 14 kWh, then 60% of that from 14 to 28 kWh, and 15% from 28 to 50 kWh. The next step-down is 1 January 2027.
Updated May 2026
Store excess solar during the day to use at night, so more of what your panels make stays in your home.
Keep essential circuits running during power outages. It matters most where the grid is unreliable.
Charge from solar or off-peak rates, then use that power in the expensive peak period.
Earn credits by sharing stored energy with the grid during demand peaks.
