Case Study: 39.78kW Commercial Solar Installation at Owston Hotel & Vin Populi
Client: Owston Hotel & Vin Populi
Project Size: 39.78kW DC Solar System
Project Type: Commercial Solar Installation
Location: Fremantle, Western Australia
Project Overview
Westsun Energy was engaged to design and install a 39.78kW commercial solar system at the Owston Hotel & Vin Populi in Fremantle.
The objective of the project was to provide a renewable energy solution that would help reduce electricity costs, support the venue’s sustainability goals, and improve long-term energy efficiency for the hospitality operations.
As a WA-based commercial solar EPC provider, Westsun Energy delivered a high-performance solar installation engineered for reliability, strong energy generation, and long-term operational performance in a busy hospitality environment.
Challenges
→ Commercial Energy Demand: Hospitality venues operate with high and consistent energy loads, requiring a system designed to deliver reliable daytime generation.
→ Rooftop Installation Constraints: Ensuring optimal panel placement while working within the structural and spatial limitations of the building.
→ Operational Environment: Installation had to be completed safely while minimising disruption to hotel and restaurant operations.
Solution
Westsun Energy engineered and installed a 39.78kW commercial solar system featuring:
→ 78 × Canadian Solar Panels: High-efficiency solar modules selected to maximise energy production across the available roof space.
→ 1 × Fronius Verto Inverter: A commercial-grade inverter delivering reliable three-phase power conversion and advanced system monitoring.
System design focused on:
→ Maximising Energy Production: Optimising panel layout and system configuration to generate strong solar output.
→ Reliable Performance: Selecting proven commercial solar components suited to Western Australian conditions.
→ Long-Term Efficiency: Delivering a system designed to support consistent energy savings and reliable performance over time.
Results & Benefits
→ Solar System Size: 39.78kW DC
→ Solar Panels Installed: 78 × Canadian Solar modules
→ Inverter: 1 × Fronius Verto inverter
→ Reduced Electricity Costs: Solar generation helps offset a portion of the venue’s daily energy consumption.
→ Improved Sustainability: Renewable energy generation supports the venue’s commitment to environmentally responsible operations.
→ Reliable Energy Production: A high-quality solar system designed to perform consistently in WA’s climate.
Conclusion
The solar installation at Owston Hotel & Vin Populi demonstrates how commercial hospitality venues can integrate solar energy to reduce operating costs and improve sustainability.
By installing a 39.78kW commercial solar system, Westsun Energy delivered a renewable energy solution designed to provide reliable performance, long-term energy savings, and support the venue’s transition toward cleaner energy.
