The Story

This Corinda household is looking at over $64,447 in lifetime savings. They will pay off the whole setup in under five years. The system includes 10.44kW of solar and a massive 27.1kWh battery.

We claimed $5,624 in government rebates to bring the upfront cost down. The panels will generate 1,200 kWh of energy annually. That power goes straight into the battery to run the summer aircon.

Energex tariffs keep climbing every single year. Storing your own power is the best way to beat the evening peak rates. This setup does exactly that.

“The crew completed the install in one day. They were very efficient and did a really neat job.”

We originally installed solar for this property back in 2017 using SolarEdge inverters. For this upgrade we AC coupled the new Sigenergy battery system. This allowed the owner to maintain their existing setup and keep using their SolarEdge optimisers without any issues.
