This paper presents the improved approach to outdoor performance testing of solar thermal collectors under quasi-dynamic test conditions. The test requirements and collector theory are closely connected to those long agreed on for steady-state testing, as described in e.g. ISO 9806-1,3 and ASHRAE 93-77.
Since the last decades, solar energy has been used worldwide to overcome foreign dependency on crude oil and to control the pollution due to a limited source of non-renewable energy.

Test facilities for air heating collectors are under construction and the first round robin air collector will be distributed in June 1982. A joint workshop was held with the International Energy Agency collector testing experts in February 1982 on the subject of solar simulators, and proceedings of this are soon to be published. Work on

This recommended qualification procedure is primarily based on the results of work performed on solar collector absorber surfaces within the framework of the International Energy Agency Program on Solar Heating and Cooling. The IEA work on solar collector absorber surfaces is reported in references given in Annex E.
The standards used to test these systems have been EN 12975-1,2 [8] and ISO 9806 [9] for solar thermal collectors and IEC 60904-1,2 [10,11] for photovoltaic modules.
collectors increased their share from close to 15% to 34%. In Europe, the situation is almost the opposite of that in China, with 72% of all solar thermal collectors installed in 2021 being flat plate collectors. In the medium term, however, the share of flat plate collectors decreased in Europe from 81% in 2011 to 72% in 2021. In contrast

solar thermal collectors testing. Historically, an American ASHRAE standard (93-77) was the first to be widely used. Then the ISO 9806 series of standards was developed and from this the EN 12975. Several national standards are available outside Europe, mostly based on the ISO 9806, whereas in Europe the EN 12975 has superseded all national
TESTING SOLAR COLLECTORS 353 or (7.4) Eq. (7.3) implies that if the efficiency is plotted against (tf.; -ta)/I t and if FR, UL, and (Ta). are constant. a straight line will result where the slope is -FRUL and the y intercept is FR(TIl) •. In reality, FRUL is not a constant but rather a function of the operating temperature of the collector and of the ambient weather

The standards used to test these systems have been EN 12975-1,2 [8] and ISO 9806 [9] for solar thermal collectors and IEC 60904-1,2 [10,11] for photovoltaic modules.
Energy Agency (IEA) is currently working within TASK 43 (IEA SHC Rating and Certification Procedures –Advanced Solar Thermal Testing and Characterization for Certification of Collectors and Systems) on the enhancement of established as well as on the development of new test procedures which are urgently needed.
There is a number of different standards describing solar thermal collectors testing. Historically, an American ASHRAE standard (93-77) was the first to be widely used. Then the ISO 9806 series of standards was developed and from this the EN 12975.
Two generically different methods are allowed by the standard to determine the thermal performance characteristics of solar collectors: The Steady State method (“SS”) and the Quasi Dynamic Test method, (“QDT”). Both methods can be used when testing for Solar Keymark certification.
Although the current version of the standard allows the use of a third collector for the mechanical load and rain penetration test, this third sample must be submitted to a pre-conditioning in the case of rain penetration taking into account the decision D8.M10 of the Solar Keymark Network [x2] (see ).
According to Keymark scheme rules, performance tests must be carried out for the smallest as well as the largest collector in a family. Therefore, at least three collectors (the smallest for performance tests and two of the largest collector for parallel performance and reliability testing) will be selected at the factory or from stock.
