The Story

Over $33,141 in estimated lifetime savings. That is what this Wellington Point household will see. We set them up with a 6.65kW solar system and an 18.1kWh battery. They now produce 100 percent of their own energy needs.

The system generates 9,778 kWh every year. That is plenty to handle heavy summer aircon use. The huge battery means they store all that subtropical sun for the evening. Energex peak rates will not bother them anymore.

The whole setup pays for itself in under 11 years. We also locked in $5,872 in government rebates for them.

“I wanted a new solar system with a battery and was recommended connect – but still got another couple of quotes. Grant did a much better job explaining my options than the other two companies – and i was pleasantly surprised that after this their quote was the most reasonable. On the day of the install Brett and his team arrived promptly, were respectful and a pleasure to have in the house and did a good job explaining the solar app before they left my house. Excellent work!”

You do not strictly need one but it makes a huge difference. Energex pays very little for solar you send back to the grid. A battery lets you store your daytime power to run your aircon at night.

How long does a residential solar and battery installation take?
We usually complete residential jobs in a single day. Our crew arrives early and gets the panels and battery sorted safely. We handle all the testing and site cleanup before we leave.

Are there still government rebates for solar in Queensland?
Yes there are solid incentives available right now. This specific Wellington Point job qualified for $5,872 in government rebates. We handle the paperwork so the discount comes straight off your upfront price.
