The Story

This Sinnamon Park home is set to save over $45,847 on electricity. We installed a 6.0kW solar array and a massive 18.1kWh battery. That means they generate about 7,300 kWh every year. It is enough power to run the summer aircon without stressing about the next Energex bill.

The client came to us through a work mate. They wanted a local team with a solid reputation. We also secured them over $4,162 in government rebates upfront. The whole setup pays for itself in under 6 years. Good gear installed right always brings real value.

“I asked a mate at work for a recommendation and Connect Energy stood out. The boys did a brilliant job and got it done with zero fuss. Everything was great value and I highly recommend them.”

We did a complete switchboard upgrade while putting in the new battery. This allowed us to properly wire in the blackout protection system. Now the house stays powered even if the grid goes down.

Frequently Asked Questions

How much solar do I need to charge an 18.1kWh battery in Brisbane?
A 6.0kW solar system works well in Brisbane. You need enough panels to cover your daytime use and fill the battery. Our subtropical sun helps max out your generation fast.
Can a solar battery run my house during a blackout?
Yes it absolutely can. We install blackout protection circuits with our batteries. This keeps your fridge running and lights on when the Energex grid drops out.
What government rebates are available for solar in Queensland?
The federal government offers upfront rebates based on the size of your solar system. We claimed over $4,162 for this specific installation. We handle all the paperwork for you.
