Commercial Solar Solution for Two Tyabb Warehouses

Case Study · Commercial Solar

Two neighbouring warehouse units in Tyabb, Victoria required independent commercial solar systems designed around their daytime energy demand. Maxwell Energy engineered and delivered two dedicated 6.6kW rooftop PV systems to increase on-site solar self-consumption, reduce electricity purchased from the grid during business hours and improve long-term operating efficiency.

Project Snapshot

Two buildings. Two independently engineered systems.

Each warehouse was provided with its own dedicated PV system and three-phase inverter, allowing the solar solution to match the independent electrical configuration and operating profile of each commercial unit.

Installed Capacity 2 × 6.6kW Independent Solar PV Systems
Inverters 2 × SolaX 5kW Three-Phase Inverters
Annual Production 8,338kWh Estimated per warehouse
Annual Savings AUD $1,451.29 Estimated per warehouse
Client Objectives

Make more use of solar where it creates value.

The client wanted a practical commercial solar solution focused on daytime self-consumption and operating efficiency, rather than simply maximising installed capacity.

01 Reduce daytime electricity costs
02 Maximise self-consumption of solar energy
03 Improve long-term operating efficiency
04 Install a reliable, low-maintenance commercial energy solution
Project Challenges

Design around two warehouses and an active commercial site.

Although the warehouses were adjacent, their electrical systems were independent. The rooftop layout also needed to accommodate existing services and equipment while normal business operations continued.

01 Two adjacent warehouses with independent electrical systems
02 Maintain normal business operations during installation
03 Optimise array layout around rooftop services and equipment
04 Prioritise self-consumption rather than excess export
Maxwell Energy Solution

Size the system around demand — not maximum roof capacity.

Maxwell Energy assessed the operating profile of each warehouse before determining system capacity. The result was two independent PV systems matched to daytime energy demand rather than simply installing the largest possible array.

01

Review Operating Demand

Consider how each warehouse uses electricity during business hours before determining the appropriate solar capacity.

02

Design Independent Systems

Provide a dedicated 6.6kW PV system for each warehouse to suit its independent electrical configuration.

03

Optimise Rooftop Layout

Use available roof space effectively while working around rooftop services and maintaining safe access.

04

Deliver Professionally

Maintain professional cable management and complete the installation in accordance with relevant Australian Standards.

COMMERCIAL ENERGY PLATFORM Dedicated SolaX three-phase inverter for each warehouse
System Architecture

Independent energy systems for independent commercial units.

Each warehouse uses its own SolaX 5kW three-phase inverter and dedicated 6.6kW rooftop solar array. This approach keeps the two electrical systems independent while allowing each installation to focus on reducing daytime grid consumption.

Warehouse 1 6.6kW Solar PV
Warehouse 2 6.6kW Solar PV
Inverter 1 SolaX 5kW Three-Phase
Inverter 2 SolaX 5kW Three-Phase
Connection Grid Connected
Project Results

Designed to improve commercial energy performance over time.

The completed systems provide each warehouse with dedicated rooftop generation focused on higher self-consumption, reduced daytime grid demand and future energy flexibility.

ESTIMATED ANNUAL GENERATION 8,338kWh Per warehouse
ESTIMATED ANNUAL SAVINGS $1,451.29 AUD per warehouse
INSTALLED SOLAR 6.6kW × 2 Independent systems
DAYTIME GRID CONSUMPTION Reduced During business operating hours
SELF-CONSUMPTION Prioritised System sizing aligned to daytime demand
FUTURE FLEXIBILITY Scalable Platform for battery storage or EV charging
Why This Solution?

The right commercial solar system is not necessarily the largest system the roof can accommodate.

Instead of applying a standard solar package, Maxwell Energy designed each system around the client's operating hours and energy consumption profile. This consultation-led engineering approach creates a balanced solution focused on long-term performance, operational savings and future flexibility.
