SA farm’s savvy battery investment

In mid-2025, the federal government announced a highly attractive new battery rebate offering 30% off storage systems until 1 January 2026, when the discount would begin to decline. The rebate is set to taper each year until 2030, when it will be fully retired.  

With batteries becoming increasingly financially viable, solar feed-in tariffs offering less return, and this new temporary rebate on the table, South Australian farm owner Zach Trethewey decided it was time to invest in energy storage to complement his existing solar system.  

He engaged commercial solar experts AllState Solar to deliver the project.  

AllState Solar proposed installing two 60kWh batteries, providing the farm with 120kWh of solar storage. This setup would maximise onsite solar consumption and further increase monthly energy savings – but also came with a significant upfront cost. 

Project snapshot

Industry: Agriculture    

Channel Partner: AllState Solar  

Battery system size: 120kWh   

Equipment:   

  • 2 x 60kwh Deye battery  

Payment Plan term: 7 years

To overcome that barrier, AllState Solar suggested that Zach use a $0 upfront Smart Ease Payment Plan to finance the project.  

By August 2025, installation of the battery system was complete.

Zach’s farm is now powered primarily by clean solar energy. During the day, electricity is supplied directly from the farm’s solar panels, while any excess energy is stored in the new battery system for use at night.  

By being proactive with his storage investment, Zach has reduced the farm’s grid reliance and significantly lowered monthly energy bills.  

Best of all, he achieved all this without spending any cash upfront – and secured a 30% discount on his equipment.  

When it comes to investing in clean energy, it truly pays off to act sooner rather than later!
