Project Overview
Client: Bullock WA
Project Size: 60kW DC Solar + 58kWh Battery Storage
Project Type: Commercial Solar & Battery System
Location: Malaga, Western Australia
Westsun Energy was engaged to design and install a 59.16kW solar system paired with 57.6kWh of battery storage for Bullock WA in Malaga.
Bullock is an Australian-owned manufacturer supplying quality products to the HVAC industry for over 35 years, with products tested to Australian standards.
The objective was to reduce electricity costs, improve energy efficiency, and increase energy independence through an integrated solar and battery solution designed to support ongoing manufacturing operations.
As a WA-based commercial solar EPC provider, Westsun Energy delivered a tailored energy solution engineered for long-term reliability and operational performance.
Challenges
→ Operational Energy Demand: Supporting consistent daytime manufacturing and operational electricity usage.
→ Battery Integration: Designing a system capable of storing excess solar generation for later use.
→ Long-Term Reliability: Delivering a durable commercial-grade system suited to industrial operations.
Solution
Westsun Energy engineered and installed a high-performance solar and battery system featuring:
→ 116 × Canadian Solar Panels: High-efficiency modules selected to maximise rooftop energy generation.
→ 2 × GoodWe ET Inverters: Delivering reliable three-phase power conversion and intelligent energy management.
→ 2 × GoodWe LX Battery Storage Units: Providing a combined battery storage capacity of 58kWh.
System design focused on:
→ Maximising Solar Generation: Delivering strong daytime output to offset operational electricity demand.
→ Battery Energy Storage: Capturing excess solar energy for use during non-peak generation periods.
→ Reduced Grid Reliance: Supporting greater long-term energy independence and operational efficiency.
