Australian clean-tech company Green Energy Systems (GES) has engaged Capral Aluminium to supply LocAl lower-carbon aluminium extrusions for the manufacture of its Solar Waves system, a new modular solar deployment innovation aimed at utility-scale projects globally.
Developed over the past two years, Solar Waves is a patented, prewired solar system designed for rapid installation across diverse environments, including land, waterways, and agricultural settings, Capral said in a LinkedIn article.
Based in Sydney, GES positions its product as a relocatable, recyclable alternative to traditional fixed solar arrays.
“The Solar Waves system is designed to be fast to deploy, easy to relocate, and acts more like a fully functioning appliance. At end of life, it can be 100% recycled. It’s a smarter way to approach utility-scale solar deployment,” said Glenn Carless, Founder and Managing Director of Green Energy System.
The Solar Waves system is delivered in pre-engineered units called “Mega Waves”, featuring a slide-together aluminium frame that allows full robotic assembly in the factory.
This design eliminates the need for conventional nuts, bolts, or clamps, reducing on-site labour and simplifying installation. Carless explained that aluminium was chosen for its strength-to-weight ratio and precision manufacturing capabilities.
GES turned to Capral Aluminium to manufacture 20 custom extrusions forming the structural backbone of the Solar Waves system.
Capral’s involvement extended beyond material supply, according to Carless, who credited the company with helping fine-tune the unique designs and connections within the modular system.
The use of Capral’s LocAl Green aluminium – produced with a certified carbon footprint of 8kg CO?e/kg or less – aligns with GES’s goal of minimising embodied carbon across the Solar Waves lifecycle.
Locally manufactured and fully recyclable, LocAl supports GES’s closed-loop design approach.
“When Leanne from Capral introduced us to LocAl and highlighted its lower embodied carbon, we knew it was exactly what we were looking for,” Carless said.
“It aligned with our sustainability goals and business aspirations.”
Capral Aluminium’s supply of LocAl to GES is backed by Aluminium Stewardship Initiative (ASI) Certification, which verifies environmental and social responsibility across the aluminium supply chain. For GES, ASI Certification was a key factor in supplier selection.
“Knowing that Capral’s aluminium meets ASI’s stringent standards gives us confidence that we are sourcing from a partner who shares our commitment to ethical production and environmental stewardship,” Carless added.
The Solar Waves system is currently being commissioned for a pilot installation over water canals in California, as part of a collaboration involving the Turlock Irrigation District, Solar AquaGrid, the University of California Merced, and the California Department of Water Resources. GES is one of only two finalists in the project’s selection process.
“This trial gives us an opportunity to demonstrate what Solar Waves can do—generate clean power, conserve water, minimise land use, and deliver all of that at an affordable cost, in one package,” said Carless.
Looking ahead, GES intends to scale production through automated facilities in both Australia and the United States to meet expected global demand.
Capral Aluminium said the collaboration with GES demonstrates the potential for Australian manufacturers to support clean energy innovation.
