Why Install a Solar Battery?

A solar battery allows you to capture the excess energy your system produces during the day – instead of exporting it back to the grid. That stored energy powers your home at night and during peak rate periods, helping you take control of your electricity usage.

With the right battery system, you can:

  • Store up to 70% of the excess solar energy your system generates
  • Dramatically reduce grid reliance
  • Avoid peak electricity rates
  • Save up to $640 per year, depending on usage
  • Move closer to operating self-sufficiently
  • Protect your household from rising energy costs
  • And, with some batteries, power your home during a blackout
Battery Rebates Available

Australian households can save around 30% through the Federal Government’s Cheaper Home Batteries Program, which provides an upfront discount on eligible battery systems.

This rebate reduces the initial investment required to install solar storage and makes energy independence more achievable for Victorian homes.

Our team will confirm eligibility, recommend a compliant system, and ensure the rebate is applied correctly to your quote.
