Solar developers and manufacturers at the Sustainable Solar Europe 2025 conference warned that the rapid expansion of sustainability and compliance frameworks across the EU is creating operational strain and long-term uncertainty—conditions that could undermine Europe’s clean-energy and manufacturing ambitions.

Regulation Overload

Industry sources said many companies have made substantial investments in compliance systems but still lack detailed, actionable guidance from policymakers.

Market participants argued that while EU regulations are intended to provide a foundation for sustainable growth, the growing level of detail and complexity is proving burdensome—particularly for smaller firms.

Companies are urging policymakers to articulate a clearer, long-term vision for sourcing critical components across the solar supply chain. Many anticipate that Europe will eventually require standardized, verifiable auditing systems supported by clear criteria and accredited auditors, especially to distinguish between the capabilities of large manufacturers and SMEs.

Supply-Chain Risk Now a Financial Priority

A recurring theme throughout the conference was the increasing role of supply-chain diligence in project finance decisions.

According to multilateral finance sources, non-module infrastructure—such as roads, substations, and transmission assets—often introduces greater risk to projects than PV modules themselves.

Finance-sector participants noted that audit fatigue is rising and that only the largest companies are currently able to absorb the costs associated with extensive due diligence. A unified certification or verification system, they said, could help reduce compliance burdens while maintaining investor confidence.

Conference attendees broadly agreed that the link between sustainability and finance is now inseparable: responsible supply chains are increasingly viewed as a prerequisite both for project development and for attracting low-risk capital.
