20kW Solar Battery Darra: Case Study Snapshot
This 20kw solar battery Darra installation shows what a large-scale system delivers for a Brisbane household.
The Story
This Darra property now generates 183% of its own energy. The new setup produces 34,659 kWh every year, covering daytime operations and easily charging the battery for later.
The homeowners originally just wanted solar. Connect Energy looked at their low nighttime usage and ran the numbers — adding an 18.1kWh battery dropped their payback period to under three years.
The project secured over $9,368 in government rebates, resulting in $157,105 in estimated lifetime savings — a highly efficient system built for the subtropical Brisbane sun.
“We had 42 Longi 475 Watt panels and a SigenStor Battery installed on our industrial shed. Connect Energy were affordable, efficient, genuine, on time and answered all my queries. Highly recommend.”
The new owners wanted a 19.95kW solar system straight away. They initially skipped the idea of battery storage because their night usage is low. We mapped out the costs and return on investment. The numbers showed a better financial outcome with the 18.1kWh battery included, and they approved the full package.

The Solution
Connect Energy installed a complete solar and battery solution for this Darra home, selecting premium equipment suited to the site’s generation profile.
System Performance
The system generates 34,659 kWh per year, with the battery storing excess daytime generation for evening and overnight use. This covers 183% of the household’s annual energy consumption.
Financial Impact
This system significantly reduces the household’s electricity costs, with savings that grow as energy prices rise.
Government incentives applied to this project included Small-scale Technology Certificates (STCs) and the Queensland Cheaper Home Batteries Program, which together reduced the upfront cost by over $9,368.
