Project Overview
Client: Porta Craft
Project Size: 59.85kW DC Solar + 96.72kWh Battery Storage
Project Type: Commercial Solar & Battery System
Location: Forrestdale, Western Australia
Westsun Energy was engaged to design and install a 59.85kW solar system paired with 96.72kWh of battery storage for Porta Craft in Forrestdale, WA.
The objective was to reduce electricity costs, improve energy independence, and maximise the use of on-site solar generation through integrated battery storage.
As a WA-based commercial solar EPC provider, Westsun Energy delivered a tailored energy solution designed to support operational efficiency, reduce reliance on the grid, and provide reliable long-term performance.
Challenges
→ Energy Management: Designing a system capable of balancing daytime solar generation with battery storage utilisation.
→ Operational Efficiency: Supporting consistent business operations while reducing exposure to rising electricity costs.
→ Long-Term Reliability: Delivering a commercial-grade integrated energy system engineered for performance and durability.
Solution
Westsun Energy engineered and installed a high-performance solar and battery system featuring:
→ 126 × Jinko Solar Tiger Neo Panels: High-efficiency modules selected to maximise energy production across the available rooftop footprint.
→ 2 × Sigenergy Sigen Hybrid Inverters: Intelligent hybrid inverter technology delivering advanced energy management and reliable system performance.
→ 12 × Sigenergy SigenStor BAT 8.0 Battery Units: Providing a total battery storage capacity of 96.72kWh for stored solar energy utilisation.
System design focused on:
→ Maximising Solar Generation: Delivering strong daytime energy production to offset operational electricity demand.
→ Battery Energy Storage: Capturing excess solar generation for use during evening periods and peak demand times.
→ Reduced Grid Reliance: Supporting greater energy independence through integrated solar and battery technology.
