Quality & Compliance

Präqualifizierung und Ausschreibungsprozesse – Der Marktzugang der Zukunft

Quality & Compliance in the Global Solar Industry

New Requirements Due to the German Supply Chain Act

Since January 1, 2023, the German Supply Chain Due Diligence Act (LkSG) has been in force. This law challenges companies to make their supply chains more transparent and legally compliant. In the solar industry in particular, the origin of materials, due diligence obligations, and liability issues are gaining major importance.

Transparency, compliance, and the proactive over-fulfillment of legal requirements are increasingly becoming key indicators of quality and competitiveness.

Tenders in the Solar Industry: Prequalification as a Key to Success

International EPCs and solar plant operators are already relying on strict prequalification processes when selecting suppliers. Only those who meet the complex compliance requirements gain access to high-value tenders.

To join the exclusive circle of preferred suppliers, providers must demonstrate compliance with comprehensive requirement catalogues. These include both legal obligations and individual, project-specific criteria defined by the clients.

The result: The expectations placed on manufacturers and suppliers of solar components—such as mounting systems—are being redefined. Prequalification has become the ticket to international projects.

Typische Anforderungen in der Präqualifikation von Herstellern

Tender documents often require proof of compliance with international norms and standards. These include:

DIN, EN, ISO, IEC standards
EN 1090-2: Execution of steel structures
EN 1990: Basis of structural design (Eurocode 0)
EN 1991-1-3 / -1-4: Actions due to snow and wind
EN 1993-1-1 / -1-8: Design of steel structures
EN 1997: Geotechnical design
EN 1998-1: Earthquake-resistant design
EN 1999-1-1 / -1-3: Design of aluminium structures

Our clients’ contracts regularly contain requirements for compliance with international, national, and regional standards and norms.

Industry recommendations from the VDE (Association for Electrical, Electronic & Information Technologies) or the AISE (American Iron and Steel Engineers) are also frequently part of the specifications.

Companies that take early action to ensure transparent supply chains, legally compliant processes, and adherence to international standards not only secure access to high-quality projects but also strengthen their position as reliable partners in the global solar market.

In the context of growing regulatory requirements and an increasingly globalized market, it is essential for EPCs and project developers to rely on partners who not only deliver in compliance with standards, but who can also meet complex demands across the entire value chain.
