18.18kW Solar System in Morningside, Brisbane

This Morningside home will save over $30,881 with their massive new solar and battery setup.

The Story

This Morningside household is on track to save over $30,881 over the lifespan of their new system. They wanted to run heavy appliances without worrying about Energex bills. We delivered exactly that.

We started by adding a massive 40kWh Sigenergy Three Phase battery back in December. We secured almost $14,000 in battery rebates for them. The goal was getting this high consumption home completely independent from the grid.

Winter sun in Brisbane can sometimes drop off. We recently added another 7.12kW of Longi 475W panels to boost their generation. The full 18.18kW setup now pays for itself in under four years.

“Great working with the Connect crew again. They hid all the cables inside the walls instead of using ugly pipes. The front of the house looks perfectly clean from the street.”

We originally fitted a 40kWh Sigenergy Three Phase battery to the existing solar array. The clients claimed almost $14,000 in government battery rebates. We noticed winter generation was occasionally falling short. We returned to install an extra 7.12kW of Longi 475W panels. This extra capacity ensures the property generates plenty of power every single day.

Frequently Asked Questions

Will solar panels produce enough power during a Brisbane winter?
Winter days are shorter and the sun sits lower in the sky. Your system will generate less power than in summer. We design your solar array to cover your daily usage even during those cooler months.

Can I add more solar panels to my existing system?
Yes you absolutely can. We often install extra panels to help charge new batteries or run heavy appliances. We just need to check your roof space and inverter capacity.

Are battery rebates still available in Queensland?
The state government offers excellent rebates for eligible battery installations. We help our clients secure these discounts upfront. This property secured almost $14,000 in rebates to significantly lower their total costs.
