Cutting Costs, Securing Power: How Schofields Shopping Village Locked in major savings in Year-1
The Challenge
Operating a modern commercial retail hub involves continuous baseline energy consumption across diverse tariff structures (Peak, Shoulder, and Off-Peak). For Schofields Shopping Village, managing predictable daytime operating margins against fluctuating grid electricity rates was a critical operational priority.
With heavy daytime loads and complex multi-rate energy consumption, facility leadership required an advanced, high-capacity renewable energy and storage architecture. The goal was to drastically curb grid reliance, hedge against rising commercial electricity tariffs, and lock in long-term operational cost certainty without compromising tenant or visitor operations.
The Engineered Solution
To address the site’s unique load profile, a robust, enterprise-grade solar PV and hybrid battery storage system was engineered and deployed under strict regulatory compliance with Endeavour Energy. The core hardware and system architecture:
Solar PV Array: 169 x Jinko Tiger Neo N-type 590W panels, delivering high-efficiency generation across optimized roof orientations.
Primary Solar Inverter: 1 x Solis S5 50kW 3-Phase 5 MPPT Inverter for seamless commercial solar conversion.
Advanced Hybrid & Storage System: 1 x Solax X3 Ultra Hybrid 3-Phase 25kW Inverter paired with a 50.4kWh Solax Battery Storage System.
Balance of System & Engineering: Comprehensive BOS, structural engineering, dual 8m scissor lift access, freight, grid connection management, and installation logistics.
Performance & Financial Impact
The completed installation immediately transforms the property’s roof space into a high-yielding, intelligent energy asset:
Immediate Financial Relief: Delivering an impressive $23,531 in Year 1 energy savings, significantly compressing operational overheads.
Optimised Efficiency & Export: Operating at a high 93.0% system efficiency, with a controlled 15.0% export percentage maximizing self-consumption on-site.
Demand Mitigation & Resilience: The integration of the 50.4kWh Solax battery storage system enables intelligent load-shifting, smoothing out peak demand windows and protecting the facility against grid instability.
This case study highlights how tailored commercial solar and hybrid battery infrastructure provides retail and commercial property trusts with long-term energy independence and immediate bottom-line impact.
