About the 15kW Solar System

The 15kW solar system represents the pinnacle of residential and small commercial solar installations. With 36 premium panels and a powerful three-phase or hybrid inverter, this system is an energy powerhouse that can transform even the highest electricity bills into manageable costs. Producing 56-68 kWh per day in North Queensland, the 15kW system generates enough electricity to run large homes with every conceivable appliance, multiple electric vehicle chargers, and commercial equipment simultaneously. For businesses, this system can offset the majority of your daytime electricity costs, delivering a rapid return on investment, typically in under 3 years. The three-phase configuration ensures balanced power delivery across all phases, which is essential for properties with heavy-duty electrical equipment. This system qualifies for the maximum STC rebate based on its size, making the effective cost significantly lower than the sticker price.

Who Is This System For?

Premium systems for high-usage homes or small commercial properties. This is our most powerful residential system, built for properties with extreme energy demands. Think large rural homes, bed and breakfasts, shops, medical practices, and light industrial premises. If you have three-phase power and high electricity consumption, this system delivers the maximum return on investment.
