13.3kW Solar + 40.3kWh Battery in Paddington, Brisbane

This Paddington home will save over $134,561 with a massive 13.3kW solar and 40.3kWh battery setup.

The Story

This Paddington property now produces 177 percent of the energy it uses. We installed a huge 13.3kW solar array and a massive 40.3kWh battery. That means they generate 21,205 kWh every single year. It completely covers their summer air conditioning and everyday power use.

The owners just bought the place. It had zero solar when they moved in. We designed a system to beat the evening energy tariffs right from the start. They secured over $9,570.50 in government rebates to bring the initial cost down.

The numbers on this job speak for themselves. The payback period is under 7 years. Over the lifespan of the gear they will save more than $134,561. That is serious money staying in their pocket.

“Had a great experience with Brett, Grant and the whole team at Connect Energy. The install of the batteries was seamless – great quality workmanship, a tidy installation and brilliant communication throughout. Would highly recommend Connect Energy to anyone looking to take control of their energy costs.”
