Bondi: 2.8kW solar + 24kWh Sigenergy battery backup

The brief

This Bondi terrace had a small, partly-shaded roof — but the owner wanted maximum energy independence and reliable blackout backup, not just bill savings.

What we installed

We installed a compact, high-efficiency 6-panel array to capture every bit of available sun, then paired it with a large 24.18 kWh Sigenergy battery and SigenStor hybrid inverter for whole-home backup. Near the coast, we used corrosion-resistant, marine-grade mounting throughout.

The result

• Bill reduction: ≈ 36% lower power bills
• Energy stored: Daytime solar stored for evening use
• Backup: Whole-home blackout protection
• Build quality: Marine-grade hardware for the coastal location
