Project Overview
Client: Banna Property Group
Project Size: 350.88kW DC Solar
Project Type: Large-Scale Commercial Solar System
Location: Kinross, Western Australia
Westsun Energy was engaged to design and install a 350.88kW commercial solar system for Banna Property Group at Kinross Shopping Centre in WA.
The objective was to reduce electricity costs, improve energy efficiency, and support the long-term sustainability of a busy retail precinct with significant daytime energy demand.
As a WA-based commercial solar EPC provider, Westsun Energy delivered a tailored solution designed to maximise solar generation and provide long-term operational savings for the shopping centre.
Challenges
→ Large Retail Energy Demand: Shopping centres experience significant daytime electricity consumption from lighting, air conditioning, refrigeration, and tenant operations.
→ Crane Lift & Site Logistics: Coordinating a large-scale crane lift to safely transport materials and equipment to the rooftop while maintaining safe access and minimising disruption within an operational shopping centre environment.
→ Operational Continuity: Ensuring installation works were completed safely and efficiently while allowing businesses within the centre to continue trading.
→ System Scale: Designing a large-scale rooftop system to maximise available roof space and energy production.
Solution
Westsun Energy engineered and installed a high-performance commercial solar system featuring:
→ 688 × Trina Solar Vertex S+ Panels: High-efficiency solar modules selected to maximise rooftop energy generation.
→ 3 × Fronius Tauro ECO Inverters: Commercial-grade inverter technology delivering reliable performance, advanced monitoring, and efficient power conversion.
→ Crane-Assisted Installation: A crane lift was used to safely position equipment and materials on the rooftop, supporting efficient project delivery and safe installation practices.
System design focused on:
→ Maximising Energy Production: Delivering strong daytime solar output to offset shopping centre electricity consumption.
→ Long-Term Reliability: Utilising proven commercial-grade equipment designed for Western Australian conditions.
→ Operational Efficiency: Supporting reduced energy costs and improved asset performance over the long term.
Results & Benefits
→ Solar System Size: 350.88kW DC
→ Solar Panels Installed: 688 × Trina Solar Vertex S+ modules
→ Inverters: 3 × Fronius Tauro ECO inverters
→ Reduced Electricity Costs: Solar generation helps offset ongoing operational expenses across the shopping centre.
→ Improved Energy Efficiency: Supports common area and tenant energy requirements with renewable energy generation.
→ Sustainability Impact: Reduced carbon emissions through large-scale renewable energy integration.
Conclusion
The Kinross Shopping Centre project demonstrates how large-scale commercial solar can help retail and commercial property owners reduce operating costs while improving long-term energy efficiency.
By installing a 350.88kW rooftop solar system, Westsun Energy delivered a solution designed for reliable performance, long-term savings, and sustainability outcomes.
The successful coordination of crane lifts, site logistics, and installation works within an active shopping centre environment highlights Westsun Energy’s capability in delivering complex large-scale commercial solar projects across Western Australia.
