The Story

290 percent energy self sufficiency is a massive result for this Camira property. We installed a huge 16.15kW solar array alongside a 45.2kWh battery. That setup produces 25,388 kWh every single year. It completely wipes out their Energex bills.

The owner originally just wanted a battery for an old system. We crunched the numbers together. A full upgrade made much better financial sense. It allowed them to claim over $10,500 in government rebates. The sub tropical sun now powers their summer aircon without a worry.

The whole setup pays for itself in under 7 years. After that it is pure profit. We estimate over $121,347 in lifetime savings for this household.

“The Connect Energy crew really know their stuff when it comes to system design. I am so glad we found them. The price was brilliant and the installation was spot on.”

The original solar was mounted on a shed separated from the main house. Digging trenches for long underground cables is usually very expensive. We avoided that massive cost by using a unique connection setup on the Sigenergy platform. We also used ethernet over power kits to solve the communication line issue. Everything talks to each other perfectly now.

Frequently Asked Questions

Can I install solar panels on a shed instead of my house in Brisbane?
Yes you absolutely can. We often install panels on separate sheds or garages. We use modern equipment to connect it back to the house without digging expensive underground trenches.
Is it better to upgrade old solar or just add a battery?
It often makes financial sense to replace the entire system. You get fresh warranties and better government rebates. We always run the numbers with you to find the best option.
How big should my home battery be to run air conditioning?
It depends on how much you run your aircon. A large battery like a 45.2kWh unit can easily run multiple air conditioners through the night. We size every battery to match your actual summer energy use.
