Partial Shipments, Phased Deliveries and Smarter Solar Site Logistics

How better planning reduces risk, labour time and programme pressure on utility-scale solar sites

On utility-scale solar projects, logistics decisions have a direct impact on installation speed, labour efficiency and overall programme certainty. Material arriving too early can congest site laydown areas. Material arriving too late can bring crews to a standstill.

When cable management logistics are planned properly, and supported by the right technical expertise, EPCs see real, measurable benefits on site.

Why logistics planning delivers tangible EPC benefits

Sites are expansive, exposed to the elements and constantly evolving as construction progresses.

Common challenges include:

• Limited or uncovered laydown areas
• Weather-related access constraints
• Multiple crews working across different blocks
• Tight installation windows

Bulk deliveries without clear phasing often lead to material being moved multiple times before it is installed, costing time, labour and increasing risk.

When logistics are planned early, EPCs benefit from:

• Faster installation rates
• Reduced material handling and rehandling
• Lower risk of damage and waste
• Better labour utilisation
• Fewer programme disruptions

These benefits compound across large sites, where even small inefficiencies are multiplied thousands of times.

How phased deliveries improve installation efficiency

Phased deliveries ensure cable management arrives in line with project sequencing, not all at once.

By working closely with EPCs, deliveries can be planned:

• Block by block
• Run by run
• In clearly labelled, easy-to-handle packaging

This approach reduces congestion, simplifies material distribution and allows installation teams to focus on installing, not sorting, storing or relocating product.

The result is a cleaner site, smoother workflows and faster progress.

Real-world impact: Aldoga 380MW solar project

The value of phased deliveries and technical planning was demonstrated on the 380MW Aldoga utility-scale solar PV project in Queensland, Australia.

Working closely with the EPC, Gripple supported a complex and fast-moving installation schedule by:

• Providing detailed take-offs and block-by-block planning
• Supplying Cable Mini Hangers and over a million metres of wire
• Phasing deliveries in line with site sequencing
• Continuously refining quantities based on installer feedback

This approach minimised overages, avoided material shortages and ensured crews were never waiting on product. As a result, the project is expected to be fully commissioned 14 months ahead of schedule, delivering significant early generation value for the asset owner.

Technical planning that starts before product leaves the factory

At Gripple, logistics planning is supported by a dedicated team of solar specialists providing highly customised technical support from initial concept through to final delivery.

Our services include:

Engineering calculations

Structural and capacity calculations tailored to your project, including:

• Structural modelling
• Catenary load and sag analysis
• Foundation calculations
• Geomembrane securement analysis

Design drawings

Detailed structural and site design drawings to:

• Support procurement efficiencies
• Promote best-practice layout
• Simplify installation sequencing

One-to-one project engineering support

Our technical managers work alongside EPC teams at every stage, providing practical advice and responsive support as site conditions and requirements evolve. By involving our team early, EPCs can evaluate different approaches and select the most efficient solution, often achieving savings on both labour and materials before construction even begins.

Logistics as part of a long-term partnership

Smarter logistics don’t happen in isolation. They are the result of early collaboration, technical understanding and a supplier who designs solutions around how EPCs actually build.

To maximise project efficiencies, involve our team as early as possible.
