Case Study: Commercial Solar & Battery Installation – Energy Cost Reduction for Logistics Operations
GT Access sought a renewable energy solution to support its operational energy requirements while reducing long-term electricity costs and carbon emissions.
With energy usage typical of a busy warehouse and logistics operation, the company partnered with M J Wallace Limited to design and install a high-capacity solar PV and battery storage system capable of delivering significant energy savings and improved energy independence.
The project aimed to maximise on-site energy generation while ensuring reliable system performance for a commercial environment.
Challenge
The facility required a renewable energy system capable of supporting high annual electricity demand while maintaining operational reliability.
Key challenges included:
- Designing a solar system large enough to offset significant daytime energy consumption.
- Integrating battery storage to increase on-site energy usage rather than exporting excess electricity.
- Ensuring the system would operate efficiently within the site’s existing electrical infrastructure.
- Providing long-term resilience against rising electricity costs.
Solution
M J Wallace Limited designed and installed a tailored commercial solar and battery system to match the site’s energy profile.
System Specification
- Solar PV Capacity: 41.7 kWp
- Solar Panels: 78 Longi Hi-MO X10 535W bifacial panels
- Inverters: 2 × Fox ESS H3 Pro 20kW three-phase hybrid inverters
- Battery Storage: 74.7 kWh Fox ESS modular lithium-ion system
- Mounting System: Renusol Metasole mounting system for sheet metal roofing
The system generates renewable electricity during the day while storing excess energy in the battery system to be used later, increasing overall energy efficiency.
Our Approach
From initial design through to commissioning, M J Wallace Limited delivered a full turnkey installation.
Our team managed:
- Detailed system design and energy modelling
- Coordination with DNO requirements
- Installation of solar panels, inverters and battery storage
- Electrical integration with the facility’s existing infrastructure
- Full testing, certification and system commissioning
By working closely with the client, we ensured minimal disruption to daily operations throughout the installation process.
Benefits
☀️ High-Capacity Solar Generation
Large-scale solar array produces significant renewable electricity during daylight hours.
🔋 Battery Energy Storage
74.7 kWh battery system stores excess solar power for later use.
⚡ Reduced Grid Dependence
Battery storage increases the proportion of electricity used on-site rather than imported from the grid.
💷 Lower Energy Costs
Renewable generation significantly reduces electricity bills.
🌱 Carbon Reduction
The system contributes to the company’s sustainability targets by reducing CO₂ emissions.
📊 Smart Energy Monitoring
Real-time system monitoring allows the client to track generation, storage and consumption.
Results
The completed installation now generates approximately 38,496 kWh of renewable electricity each year, significantly reducing reliance on grid electricity.
Battery storage increases on-site energy utilisation, allowing the facility to use stored solar power outside peak generation hours.
The project demonstrates how commercial solar and battery systems can help businesses control energy costs while supporting long-term sustainability goals.
