Overview

Protecting innovation for solar at scale.

When Neoen and Bouygues joined forces to deliver one of Australia’s largest solar farms, they needed more than just compliant components - they needed solutions that didn’t exist yet.

With over 800,000 cables to manage and tight installation timelines, Identimark engineered two entirely new products to get the job done..

82,000 hangers installed in just 4 days (vs. expected 3-4 weeks)

Custom galvanised motor bridges designed & delivered

Rotag laser impregnated marine grade aluminium tags.

Labour costs significantly reduced through efficient installation

Challenge

What Needed To Be Solved.

The Culcairn Solar Farm project wasn’t just large, it was logistically complex and under intense pressure to meet deadlines.

With over 800,000 cable hangers required, the original installation estimates threatened both labour budgets and the overall schedule.

The site’s use of Nextracker’s moving torque tube system also created a unique technical hurdle: routing cables over the motors safely, without interfering with their movement or breaching compliance.

Delays or missteps in material delivery could ripple into costly project hold-ups.

Key challenges included:

Labour efficiency: Thousands of cables needed to be installed fast to keep project costs under control.

Torque tube interference: String cables needed a secure and tidy routing system to pass over the Nextracker torque tube motors without impacting system function.

Risk of project delays: With large contractor teams on-site, work stoppages due to delayed materials would lead to project delays and cost overruns.

Engineering the Answer.

Over two years, Identimark partnered with Bouygues to design, test and deliver a tailored cable management system for Nextracker infrastructure.

We developed a tool-free, fast-fit cable hanger that cut install time from weeks to days, and a custom galvanised motor bridge to route cables safely and cleanly over torque tubes.

These solutions didn’t just solve the problem — they redefined the standard for solar cable management.

Nextracker-Compatible Cable Hangers

Designed specifically for the Nextracker system, these hangers allowed for rapid installation, cutting expected labour time dramatically.

The first 82,000 hangers were installed in just four days—a process that was initially estimated to take three to four weeks.

Custom Galvanised Motor Bridges

Identimark developed bespoke galvanised steel bridges to safely guide string cables over the Nextracker motors, ensuring a tidy and secure installation that would not interfere with system movement.

Cable Labels & Ties

High-quality UV-resistant cable labels and coated zip ties ensured clear identification and long-term durability in harsh outdoor conditions.
