Certification for Solar Thermal Storage Systems: Ensuring Efficiency and Reliability

The increasing demand for renewable energy sources has led to a surge in the development and deployment of solar thermal storage systems. These systems play a crucial role in harnessing the power of the sun and storing it for later use, providing a reliable source of energy during periods of low sunlight or at night. However, with the proliferation of these systems comes the need for certification programs that ensure their efficiency, reliability, and safety.

Certification is essential to guarantee that solar thermal storage systems meet specific performance standards, adhere to industry best practices, and are safe for installation and operation. In this article, we will explore the importance of certification for solar thermal storage systems, highlight key certifications, and provide detailed information on what to expect from these programs.

Key Certifications:

Several organizations offer certification programs for solar thermal storage systems, each with its own set of requirements and standards. Some of the most prominent certifications include:

  • International Electrotechnical Commission (IEC) 62461: This standard sets out performance requirements for solar collectors used in solar thermal power plants.

  • Solar Keymark: Issued by the European Solar Test Performance Laboratory, this certification ensures that solar thermal systems meet specific safety and performance standards.

  • Institute of Electrical and Electronics Engineers (IEEE) C57.13.4: This standard outlines the testing and evaluation procedures for dry-type transformers used in solar thermal power plants.

    Here are two detailed paragraphs explaining key aspects of certification programs:

    Design and Testing Requirements:

    Solar thermal storage systems must undergo rigorous design and testing to ensure their efficiency, reliability, and safety. Manufacturers must submit their products for evaluation by independent third-party laboratories or testing centers. These evaluations assess the systems performance under various conditions, including extreme temperatures, high pressures, and varying sunlight intensities.

    Key aspects of design and testing requirements include:

  • System configuration and layout

  • Material selection and durability

  • Thermal performance and efficiency

  • Pressure vessel integrity and leak testing

  • Electrical safety and arc fault protection


  • Manufacturers must also provide detailed documentation, including schematics, drawings, and test reports. This information is used to verify compliance with industry standards and regulations.

    Compliance with Industry Standards:

    Solar thermal storage systems must comply with a range of industry standards and regulations. These include:

  • International Building Code (IBC) and National Electric Code (NEC)

  • American Society for Testing and Materials (ASTM) specifications

  • European Union directives, such as the Machinery Directive (2006/42/EC)


  • Compliance with these standards ensures that solar thermal storage systems meet specific requirements for safety, performance, and environmental impact. Manufacturers must demonstrate their products compliance through documentation and testing.
