10kW Solar Battery Bardon: Case Study Snapshot

This 10kw solar battery Bardon installation shows how a hail-damage upgrade turned into a complete energy independence system.

The Story

This Bardon property now generates 133% of the power it needs. The owners expect over $98,971 in lifetime savings. A bad hailstorm smashed their old panels, and insurance covered the replacement — Connect Energy stepped in to upgrade the whole setup.

The new system pairs 9.5kW of solar with a 24.2kWh battery. The homeowners claimed over $7,458 in government rebates, and the system produces 13,268 kWh a year, comfortably covering heavy summer aircon use.

The payback period sits at under 6 years. Whole-home blackout protection was also wired in, so when Energex drops out during summer storms, the lights stay on.

Installation Photos

Installer notes: Hailstorms wrecked the existing panels on this property. Insurance paid to strip and replace the damaged gear. We used the opportunity to add a large battery system, and also wired in whole home blackout protection to keep things running during grid faults.

Frequently Asked Questions

Does insurance cover hail damage on solar panels?
Most home insurance policies cover solar panels damaged by hail. You need to check your specific policy documents. We replace systems damaged by storms across Brisbane all the time.
What does whole home blackout protection actually do?
It automatically switches your house to battery power when the Energex grid fails. Your fridge stays cold and the lights stay on. We wire this directly into your switchboard.
Will a big battery run my air conditioning all night?
Yes it absolutely will. A battery that size stores plenty of energy for typical summer cooling. Your exact runtime depends on the size of your unit and your temperature settings.
