Overview

EN ISO 24194:2022/A1:2024 is Amendment 1 to ISO 24194:2022, published by CEN in March 2024. It updates the international standard ISO 24194 - Solar energy - Collector fields - Check of performance. The amendment does not change the overall scope of the parent standard but introduces clarifications and technical corrections to symbols, units and formula notation used throughout the document. National implementation in CEN member countries was required by September 2024.

Key topics

  • Symbol and notation updates: Systematic replacement and indexing of several symbols (for example, alpha, temperature and other parameters) across clauses, examples and annexes to improve clarity and consistency.
  • Formula refinements: Corrections to formula references and variables in key clauses (sections 5 and 6) and worked examples for performance estimation.
  • Unit correction: Correction of heat-transfer related unit notation (e.g., thermal conductivity/heat loss coefficient unit expressed correctly as W/(m·K)).
  • Illustration/figure edits: Updates to figure labels related to irradiance and shading (e.g., shadowing on fixed collectors in rows).
  • Annex adjustments: Aligned symbol usage and formulae in Annex A and Annex B to reflect editorial and technical corrections.
  • Standards governance notes: Confirms adoption under CEN rules and draws attention to possible patent rights and national implementation obligations.

Applications

Who uses EN ISO 24194:2022/A1:2024 and why:

  • Solar thermal system designers and engineers - to ensure consistent computation and verification of collector-field performance.
  • Test laboratories and certification bodies - for repeatable, standardized checks of collector field output and to interpret performance equations correctly.
  • Project developers and asset owners - to validate expected thermal yields and support commissioning or performance acceptance testing.
  • Researchers and academics - for consistent notation when comparing or publishing field-performance studies.
  • Standards committees and regulators - to harmonize national regulations and procurement specifications referencing ISO 24194.

Practical uses include performance checks for non-concentrating and low-focusing collectors, evaluating shading impacts, and setting up equations for field performance estimates.

Related standards

  • ISO 24194:2022 (base standard) - Collector fields: check of performance.
  • Developed by ISO/TC 180 (Solar energy) in collaboration with CEN/TC 312 (Thermal solar systems and components).

Keywords: EN ISO 24194:2022/A1:2024, ISO 24194 amendment 2024, solar energy standard, collector fields, check of performance, solar collector testing, solar thermal performance.

Solar energy - Vocabulary (ISO 9488:2022)
SIST EN ISO 9488:2022

This document defines basic terms relating to the work of ISO/TC 180. The committee covers standardization in the field of the measurement of solar radiation and solar energy utilization in space and water heating, cooling, industrial process heating and air conditioning. Consequently, the vocabulary within this document is focussed on definitions relating to those measurement and utilisation technologies.
Since the 1999 version of this document there has been considerable development in solar photovoltaic technologies and high temperature solar thermal technologies that use heat to produce electricity or to provide high temperatures for processes that require elevated temperatures. This standard has some definitions that are useful also for those technologies; however, there are other documents that cover vocabulary for these technologies in more detail.

External auxiliary water heating devices that are placed in series with the factory made system are not considered to be part of the system. Cold water piping from the cold water grid to the system as well as piping from the system to an external auxiliary heater or to draw-off points is not considered to be part of the system. Piping between components of the factory made system is considered to be part of the system. Any integrated heat exchanger or piping for space heating option (see Introduction, last paragraph) is not considered to be part of the system.

Thermal solar systems and components - Custom built systems - Part 5: Performance test methods for control equipment
SIST EN 12977-5:2018

This European Standard specifies performance test methods for control equipment. Furthermore, this document contains requirements on accuracy, durability and reliability of control equipment.
The tests described in this document are limited to electrically activated components delivered with or for the system by the final supplier. For the purposes of this document controller and control equipment for solar heating systems and auxiliary heaters, if part of the system, are restricted to the following:
a)   Controllers as:
1)   system clocks, timers and counters;
2)   differential thermostats;
3)   multi-function controllers.
b)   Sensors as:
1)   temperature sensors;
2)   irradiance sensors (for short wave radiation);
3)   pressure sensors;
4)   level sensors;
5)   flow meters;
6)   heat meters.
c)   Actuators as:
1)   pumps;
2)   solenoid and motor valves;
3)   relays.
d)   Combinations of controllers, sensors and actuators listed above.
An additional objective of the procedures described in this document is to verify control algorithms and, together with the accuracy of sensors, to determine control parameters. In addition to verifying the functioning of a controller, its equipment and actuators, the determined parameters may be used for numerical system simulations.
Typically, electrical anodes are not part of the control equipment and are not controlled by the control equipment. However, because they are electrical appliances, electrical anodes are included in this document.
This document is valid for control equipment of solar heating systems for the purpose of hot water preparation and/or space heating. If the solar system is connected to or part of a conventional heating system, the validity is extended to the entire system. In combination with the standards EN 12976-1, EN 12976-2 as well as EN 12977-1, EN 12977-2, EN 12977-3 and EN 12977-4, this document is valid for
e) factory made solar heating systems,
f) small custom built solar heating systems,
g) large custom built solar heating systems,
h)   auxiliary heater equipment used in connection with e), f) and g).
