Brussels, BELGIUM (25 March 2026): The Solar Stewardship Initiative (SSI) today announces the first two manufacturing sites certified against its Supply Chain Traceability Standard, marking a significant milestone in strengthening transparency and due diligence across the solar value chain.
The certified and transactions in line with the requirements of the SSI Supply Chain Traceability Standard.
The SSI Supply Chain Traceability Standard, published in December 2024, is designed as a practical, sectors specific framework to ensure companies are identifying and addressing risks in their supply chains, strengthening transparency, and alongside with the SSI ESG Standard, demonstrating credible due diligence across complex global supply chains. Together, the two Standards provide assurance that the systems and controls needed for responsible sourcing and material traceability are in place across the supply chain, from upstream production through to solar module manufacturing.
Importantly, certification at this stage reflects system readiness and capability, rather than a predefined volume of traceable material. Certified sites are able to trace materials and transactions to meet the requirements of the SSI Supply Chain Traceability Standard and requests of customers seeking traceable products. The scale of traceable flows will grow as demand for traceable materials – either from buyers, investors or governments – grows across the market.
Rachel Owens, CEO of the Solar Stewardship Initiative (she/her), said: “These first traceability certifications are an encouraging first step to demonstrate that auditable traceability systems can be implemented within the solar sector. As public and regulatory expectations increase, including under the EU Forced Labour Regulation, companies are being asked to demonstrate effective due diligence and supply chain visibility. Continued progress will depend on collaboration across the value chain. Scaling traceable material flows will require engagement from manufacturers, buyers, investors, international financial institutions, and civil society.”
Certification against the SSI Supply Chain Traceability Standard provides independently verified evidence of traceability systems, supplier level traceability information and documentation. As more sites undergo assessments, buyers will have access to stronger and more reliable data to support due diligence and compliance processes, while manufacturers will be able to demonstrate their readiness to support compliance with emerging legal and market expectations.
