Product Sustainability and Responsible Sourcing

Product Sustainability

Sustainability is embedded into each phase of our product lifecycle, from our partnerships with suppliers to our manufacturing practices. Array’s product lifecycle includes four distinct phases:

Sourcing
We source our materials from suppliers that share our commitment to sustainability. We prefer to use recycled aluminum or recycled steel whenever possible to reduce our overall impact, and we identify opportunities to source components that are highly recyclable at the end of their useful life.
Manufacturing
In our manufacturing, we seek to minimize waste, enhance the sustainability of our operations, and ensure that our products are made responsibly. For example, we collect the aluminum shavings from our manufacturing operations to form condensed pucks of aluminum for more efficient recycling. Please see the environmental section for more information about how we incorporate sustainable practices into our manufacturing process.
Installation
During the installation phase, we offer training to customers on product installation to help ensure the quality and durability of our systems.
End of Life
In our installation manual, we provide our customers with guidance on proper disposal of the tracker system at the end of its 30-year lifecycle. Our customers have not retired any sites to date, but we will have more robust data about the rates of recyclability of our products when they reach the end of their useful life.

Supply Chain Management and Responsible Sourcing

We follow a thorough supplier vetting process that helps ensure compliance with all applicable laws. This process leads suppliers through several stages to evaluate their approach to capacity, strategic sourcing, supplier selection, procurement, inventory, engineering, and capability. Each step provides an opportunity for incremental reviews. This process is designed to address critical issues in supply chain management and reflects our risk-based approach to ensuring that our suppliers comply with our quality, environmental and social standards. Our environmental standards include evaluating environmental performances of their activities, ensuring efficient use of water and energy, and working to reduce hazardous waste and emissions. Our social standards include respecting human rights and providing a safe, secure, and healthy workspace for all employees. To increase supplier transparency, our supplier quality engineers conduct regular supplier audits to ensure that suppliers are adhering to the Supplier Quality Manual, which includes ISO 9001, 14001 and 45001 standards. Furthermore, we are continually working to expand the recycled content of our products to ensure that we are sourcing responsibly and improving the environmental profile of our systems. Through strategic partnerships with suppliers like Nucor, we are working to increase the supply of green steel used in our trackers, which not only lowers the embedded energy, carbon, and water impacts of our sourcing, but also improves the recyclability of our products at the end of life.

Product Safety and Quality

We have established programs for Manufacturing Engineering and Packaging Engineering to drive product quality outcome improvements. We are underway with a layout transformation of our Albuquerque facility that includes the purchase of new, more energy efficient saws for production and major refurbishment of existing equipment to improve process control of our production processes. We planned a Lean transformation of our manufacturing operations to reduce waste and streamline our work processes. We have engaged all our employees in training programs with expert consultants to drive cultural transformation. Lean projects will drive improvements in safety by reducing strain and improvement ergonomics of the production processes. Quality Array maintained its status as an ISO 9001:2015 certified organization passing its external audit without any non-conformities. Our Quality Management System includes design, supply, manufacture, and commission of Array solar tracker systems. Key processes with our Quality Management System include:

  • Vendor Approval Process: Utilize robust auditing practices to qualify potential suppliers and ensure existing suppliers maintain our quality standards.
  • Production Part Approval Process: Verify each supplier has effective and sustainable manufacturing practices for each part they produce for Array.
  • Corrective Action Process: Capture issues to investigate root causes to prevent occurrence and recurrence in similar situations.
Advancing Safety and Quality

Our quality objectives focus on risk reduction, opportunity enhancement and ensuring effective process control to prevent defects. In addition to maintaining our status as an ISO 9001 certified organization, we invested in product safety and quality by establishing the Array Tech Research Center and hiring a Manufacturing Engineer and a Packaging Engineer. We are also members of the Asociación Técnica Española de Galvanización (ATEG).

The Array Tech Research Center

We established the Array Tech Research Center in 2021 in Phoenix, Arizona, to accelerate tracker innovation, strengthen customer collaboration and create a space dedicated to researching, developing, and field testing advanced solar tracker technology. This allows us to constantly improve our products and create solar trackers that are highly durable with a fully passive, failure-free wind-load mitigation system that do not rely on sensors or electricity.

ATEG Membership

To further ensure that our trackers can endure extreme weather events, and to prevent the metal components of our solar trackers from functionally deteriorating over time through corrosion, we are members of ATEG – Asociación Técnica Española de Galvanización. This organization promotes technical research and the improvement of the environmental management of the anti-corrosion treatment process, which allows us to provide the highest confidence of quality.

Supplier Code of Conduct

As part of our ESG due diligence and supplier vetting process, our team requests that suppliers sign a Master Service Agreement (MSA), which includes the environmental and social standards that are outlined in our Supplier Code of Conduct. For suppliers that are unable to sign an MSA, our legal team developed a Supplier Compliance Certificate or reviews the supplier’s Code of Conduct to ensure that their business practices align with our standards.
