Your partner through every step of your renewable journey. Towards a Zero Carbon Footprint Future.
From 1 July 2025, take advantage of the Federal Cheaper Home Batteries Program and enjoy around 30% off your battery purchase upfront.
Zero Energy is making it even easier for Victorians to go solar-smart with our exclusive battery offers—perfect for storing solar energy and powering your home day or night.
With Victoria’s feed-in tariffs now lower than ever, it’s the ideal time to install a home battery. Store your excess solar, reduce grid reliance, and slash your electricity bills.
During the day, solar panels generate electricity from sunlight (DC power).
This electricity first powers your home appliances and lights directly.
Any unused or surplus energy is automatically sent to charge the battery instead of going to the grid.
When the sun goes down or your solar production drops, your home draws electricity from the battery.
If the battery is empty, or the usage exceeds battery capacity, your home will automatically draw from the grid.
To rovide backup power during grid outages—keeping essential appliances like fridges, Wi-Fi, and lights running.
Get a 6.6kW solar system with significant savings after applying your STC and Solar Victoria rebates. Plus, access an interest-free loan from Solar Victoria to further reduce your upfront payment.
Need more power? Upgrade to a 10kW solar system and enjoy great value post-rebates and with the support of a Solar Victoria loan.
