The Story

This Bardon property now generates almost all its own power. We installed a new 8.075kW solar setup and an 18.1kWh battery. The numbers speak for themselves. The system will save them over $113,515 during its lifetime. They will pay it off in under four years.

Summer aircon bills used to hit hard. Now they generate 11,793 kWh a year from the Queensland sun. We secured over $6,225 in government rebates to bring the upfront cost down. The design fits perfectly around their upcoming home renovations.

Good design means avoiding headaches later. We mapped the roof space carefully. Now they have a massive battery reserve for the evenings. They hardly draw anything from the Energex network anymore.

“The neighbourhood group chat recommended Connect Energy and I am so glad I listened. The crew did an awesome job and made the whole process easy. Really happy with the outcome and the new setup.”

We designed this 8.075kW array and 18.1kWh battery specifically for the available roof space. The owners have renovations planned soon. We mapped the panel locations carefully to avoid any conflicts with their upcoming building work. Proper sizing ensures they meet their high energy needs.
