Overview
EN 12975:2022 - Solar collectors - General requirements (CEN) is a European standard that defines performance, durability, reliability and safety requirements for fluid-heating solar collectors. Applicable to all types of collectors where the collection process can be separated from thermal storage, this standard focuses on the collector itself (not assemblies or fully integrated storage devices). EN 12975:2022 supersedes EN 12975-1:2006+A1:2010 and aligns testing references with EN ISO 9806:2017, introduces the gross yield concept and formalizes collector family rules.
Key topics and requirements
- Scope: Applies to all fluid-heating solar collectors; excludes devices where storage is integral and inseparable from collection.
- Testing and performance:
- Requires testing largely according to EN ISO 9806:2017 (see Annex A for conversions from earlier test results).
- Reports gross solar yield (GSY) and, for cogenerating collectors, gross thermal yield (GTY) and gross electric yield (GEY).
- Gross yields must be reported for selected locations (Athens, Würzburg, Strasbourg, Davos) and operating temperatures 25 °C, 50 °C, 75 °C (Annex B).
- Durability, reliability and safety:
- Compliance criteria include passing required tests without "major failure" ratings per EN ISO 9806.
- Fire-safety guidance: reaction-to-fire and external-fire tests per EN 13501-1 and EN 13501-5 with sample preparation guidance in Annexes E and F.
- Documentation and labelling:
- Mandatory technical documentation: bill of materials, fully-dimensioned drawings, material specifications.
- Required labelling: manufacturer, model, serial number, production year, peak power, maximum operating pressure, empty weight, etc.
- Additional concepts:
- Collector families and design tolerances (Annex C).
- Retesting guidelines (Annex D).
- Recommended (but not always mandatory) tests such as pressure-drop measurement and specific fire tests.
Applications and practical value
EN 12975:2022 is used to:
- Demonstrate thermal performance, safety and durability of solar collectors for product certification and market access in Europe.
- Provide a consistent testing and reporting basis for manufacturers, independent test laboratories and certification bodies.
- Support procurement specifications, product comparison, and compliance checks for installers, system designers and building authorities.
- Inform product documentation and labelling required for installers and end users.
Keywords: EN 12975:2022, solar collectors, fluid heating, thermal performance, gross solar yield, EN ISO 9806:2017, fire safety, collector testing, collector families.

Annex C shall be considered for solar collector families and Annex D for modifications of solar
collectors.
5.2 Tests
Collectors shall be tested according to Table 1 of EN ISO 9806:2017 except for the pressure drop
measurement which is not required. The results shall be reported as required in the corresponding
clauses and as defined in Annex A of EN ISO 9806:2017. Results determined under the previous
standards EN ISO 9806:2013 and EN 12975-2:2006 can be converted according to Annex A. If Annex A

product label, both providing at least the information listed in Clause 6. For families of collectors the
documentation shall cover all members of the family.
5.4 Performance indicators
The gross solar yield GSY(ϑ ,Loc) shall be reported at least for the locations Athens, Würzburg,
op
Strasbourg and Davos for operating temperatures of 25 °C, 50 °C and 75 °C following Annex B. For co-

Die Norm EN 12975:2022, mit dem Titel „Solar collectors - General requirements“, bietet eine umfassende Grundlage für alle Arten von Flüssigkeitserwärmenden Solarcollectoren. Diese Norm legt klare Leistungsanforderungen für Flüssigkeitserwärmende Solarcollector fest, die sich auf essenzielle Aspekte wie Haltbarkeit, Zuverlässigkeit, Sicherheit und thermische Leistung konzentrieren. Ein wesentlicher Schwerpunkt der Norm liegt auf der Definition und Festlegung von Anforderungen, die sicherstellen, dass Solarcollectoren unter verschiedenen Bedingungen zuverlässig und sicher funktionieren. Die Stärken der EN 12975:2022 manifestieren sich in ihrer Fähigkeit, die Qualität und Leistung von Solarcollectoren zu gewährleisten, was für Hersteller und Anwender von entscheidender Bedeutung ist. Durch die Festlegung von Standards für die thermische Leistung und andere relevante Parameter leistet diese Norm einen wichtigen Beitrag zur Förderung der Nachhaltigkeit und Effizienz in der Solarenergiebranche. Had die Norm klar umrissene Bereiche, die sie abdeckt, so konzentriert sie sich insbesondere auf den Solarcollector selbst und nicht auf Systeme oder Baugruppen, die eine thermische Speichereinheit enthalten. Dies sorgt für eine präzise Anwendung der Leistungsanforderungen und vermeidet Verwirrung in der Anwendung. Die Relevanz von EN 12975:2022 ist unbestreitbar, da sie als Leitfaden für die Entwicklung und Bewertung von Solarcollectoren dient. Dadurch unterstützt sie nicht nur die Industrie, sondern auch Biomasse- und Erneuerbare-Energien-Projekte, indem sie verlässliche Daten und Kriterien zur Verfügung stellt, die zur Planung und Implementierung dieser Systeme verwendet werden können.

One of the key strengths of this standard is its focus on the essential parameters that define the quality and functionality of solar collectors. By emphasizing performance requirements pertinent to thermal performance, reliability, and safety, EN 12975:2022 addresses vital aspects that directly influence the efficacy of fluid heating systems. This relevance is particularly significant as the demand for effective renewable energy solutions continues to grow in response to environmental concerns and energy efficiency goals. Furthermore, the standard delineates its scope clearly by focusing exclusively on the solar collector itself, excluding assemblies that integrate thermal storage units. This targeted approach allows for more precise assessments and measurements of thermal performance, ensuring that stakeholders can evaluate collectors in a manner that reflects their intended operational capabilities effectively. Overall, EN 12975:2022 stands out as a robust framework that not only enhances the quality of solar collectors but also supports industry stakeholders in meeting rising energy demands while adhering to safety and performance benchmarks. Its relevance in the renewable energy landscape remains paramount, making it an essential reference for manufacturers, engineers, and regulators involved in the design and implementation of fluid heating solar collectors.
