Technical FAQs 4

What are the requirements for a European solar installation?

Equipment deployed in European solar installations must meet stringent standards and certifications to ensure safety, reliability, and performance. Solar panels and associated equipment must carry the CE marking, indicating compliance with EU health, safety, and environmental protection standards.

Why should solar projects be regulated in Europe?

Navigating European solar regulations demands precision and strategic compliance management across every phase of energy projects. Energy regulatory compliance shapes the foundation of successful renewable installations, determining project viability, operational efficiency, and long-term sustainability.

Do solar inverters have to comply with en 50549?

Inverters must comply with EN 50549, which specifies requirements for connecting to the power distribution network. Energy storage systems, increasingly common in solar installations, require UN 38.3 certification for lithium batteries and must meet IEC 62619 standards for safety requirements.

What role does distributed energy play in Europe's power grid?

As renewable energy continues to grow in Europe, distributed energy resources—such as solar power, energy storage systems, wind energy, and hybrid systems—are playing an increasingly vital role in the power grid.
