Project Overview

Client: Metso – Stage 2
Project Size: 200kW DC Solar
Project Type: Rooftop Commercial Solar System
Location: Canning Vale, Western Australia

Westsun Energy was engaged to deliver Stage 2 of a commercial solar installation at Metso in Canning Vale, expanding the site’s renewable energy capacity with an additional 200kW DC system.

The objective was to further reduce electricity costs, increase on-site solar generation, and support the client’s long-term energy and sustainability strategy.

As a WA-based commercial solar EPC provider, Westsun Energy delivered a system designed to integrate seamlessly with existing infrastructure while maximising performance and reliability.

Challenges

System Expansion: Integrating Stage 2 with the existing solar installation while maintaining system performance and consistency.

Operational Continuity: Coordinating installation works with minimal disruption to ongoing site operations.

Maximising Output: Designing a system that efficiently utilises available roof space to deliver strong energy generation.

Solution

Westsun Energy engineered and installed a high-performance commercial solar system featuring:

400 × 500W SunPower Solar Panels: Premium high-efficiency modules selected to maximise energy production across the available rooftop footprint.

2 × SMA Three-Phase Inverters: Delivering reliable power conversion with strong performance for commercial-scale systems.

System design focused on:

Maximising Energy Production: Delivering strong solar output to further offset grid electricity consumption.

Seamless Integration: Ensuring compatibility with the existing solar infrastructure on site.

Reliable Performance: Using proven commercial-grade components suited to Western Australian condition

Results & Benefits

Solar System Size: 200kW DC

Solar Panels Installed: 400 × 500W SunPower modules

Inverter Capacity: 2 × SMA three-phase inverters
