Overview
ISO 24194:2022/Amd 1:2024 is the first amendment to the international standard ISO 24194:2022, titled Solar energy - Collector fields - Check of performance. This amendment, published in March 2024 by the International Organization for Standardization (ISO), introduces updates primarily to the mathematical symbols and notations used throughout the standard. The standard is developed by ISO Technical Committee ISO/TC 180, Subcommittee SC 4 focused on solar thermal systems, in collaboration with the European Committee for Standardization (CEN/TC 312).
The amendment improves clarity and consistency within the standard’s documentation and formulas for evaluating performance in solar collector fields. This ensures better harmonization and facilitates accurate performance checks of solar thermal collector systems globally.
Key Updates
The main changes introduced by ISO 24194:2022/Amd 1:2024 include:
- Symbol Replacements: Various symbols used in equations and performance checks have been replaced to improve clarity. For example, the generic symbol "a" has been replaced with "1,∆Q_a1," and "T" replaced with "∆Q_a2" among others.
- Formula Adjustments: Formulas related to non-concentrating and non- or low-focussing collectors now incorporate updated symbols to accurately reflect performance parameters.
- Units Clarification: Units for thermal measurements in collector pipes have been standardized to W/(m·K), replacing older or ambiguous units.
- Notation Consistency: Symbols representing solar irradiance, shadows on fixed collectors, collector area ratios, and other thermal system parameters have been systematically updated to align with international best practices.
- Examples Updated: Example calculations provided in the original standard have been recalibrated with the new symbols for enhanced usability.
These changes directly impact how solar energy professionals perform performance verification and modeling of solar collector fields, ensuring that the outputs are standardized and reliable.
Applications
The ISO 24194:2022/Amd 1:2024 amendment is essential for professionals and organizations involved in:
- Solar Thermal System Design: Engineers designing solar collector fields can apply the updated standard to verify system efficiency and optimize performance.
- Performance Testing and Validation: Testing laboratories and certification bodies use the revised symbols and procedures to assess collector fields’ operational output accurately.
- Research and Development: R&D teams enhance solar collector models based on harmonized formulas to innovate system efficiency.
- Installation and Maintenance: Service providers rely on the standard for maintenance diagnostics and ensuring expected performance thresholds are met.
- Regulatory Compliance: National and international authorities incorporate the updated standard to align solar thermal system approvals with current best practices.
By adopting the amendments, organizations can ensure compliance with the latest solar energy collector field performance review techniques, improving system reliability and energy yield predictions.
Related Standards
ISO 24194:2022 and its amendment relate closely to several other standards in the solar energy and thermal system domain:
- ISO 9806 - Thermal solar systems - Test methods for solar collectors
- ISO 9459 - Solar heating system performance testing
- EN 12975 - Thermal solar systems and components - Solar collectors - Testing and requirements
- IEC 62862 - Concentrated solar power (CSP) systems - Performance testing
- CEN/TC 312 standards on solar thermal systems and components
These standards together create a comprehensive framework for the design, testing, and verification of solar thermal technologies worldwide.
Implementing ISO 24194:2022/Amd 1:2024 ensures that solar collector field performance checks meet enhanced accuracy and consistency. It facilitates better global alignment among manufacturers, installers, and regulators committed to advancing solar thermal energy solutions.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
