“Our $600 quarterly bills are gone.”
Ross & Holly, Bilambil Heights

The job

Ross and Holly are both self-employed and use their home as a business base: a three-bedroom, two-bathroom home with a garage workspace. They had been looking into solar for two to three years, and every company they spoke to sounded the same. After the cyclone outage they decided it was time, and wanted a system that was cost-effective, reliable and future-proof.

What we installed

• Solar: 19 kW of AIKO panels (40 panels) on a Colorbond roof
• Battery: a Sigenergy battery in the garage, since expanded to 33 kWh
• Ready for the future: sized with room to grow, including EV charging

How it went

The Sigenergy battery went in the garage, compact and tidy. Sigenergy’s modules stack, which is why the battery could be expanded later as the household’s needs grew. Before install day we did a face-to-face site visit to agree the battery position, check the switchboard and confirm what runs in a blackout, so there were no surprises on the day.

Today the home, including the garage workspace, is powered by solar and battery, so the air-con, washing machines and tools can run without worrying about cost, and storms and outages are no longer a stress.
