 In Case Studies

A 17.39 kW solar system and a 48.4 kWh Sigenergy SigenStor battery built into a new two-storey home in Highton, with seven months of measured results.

Location: Highton, Geelong
Switched on: February 2026
System: 17.39 kW solar with a 48.4 kWh Sigenergy SigenStor battery (three-phase) on a new two-storey home

A local homeowner in Highton had our team fit a 17.39 kW solar system and a 48.4 kWh Sigenergy SigenStor battery to their new two-storey home. The system runs on a three-phase supply and was switched on in February 2026.

Because the home was a new build, the cabling was pre-wired through the house to its final locations. Scaffolding was used for safe roof access.
