"Family" certification process
In order to reduce costs and simplify the procedures, the Solar Keymark scheme foresees the possibility of certification of a product family, be it a collector or a system.
Collector “families”
If the manufacturer produces the “same” collector in different lengths and/or widths
(i.e. the only difference between two collectors is the length and/or the width) the
collector is considered the same subtype (within the same collector “family”).
In this case only one sample of the smallest and one sample of the largest module shall be taken and tested.
Note: the module sizes are compared based on aperture area. Aperture area is defined in EN 12975-2, Annex I. The inspector shall inspect all the different sizes of the type to verify conformity.
The largest module shall be subject to all the tests required in EN 12975-1 clause 5.2, and the smallest shall be subject to a thermal performance test (clause 6 of EN 12975-2). The performance figures used for this type shall be the performance figures corresponding to the measured instantaneous efficiency having the lowest integral in the interval of the reduced temperature from 0 – 0.1 K/(W/m²).
Note: The reduced temperature is defined in EN 12975-2, paragraph 6.1.4.8.3, and the instantaneous efficiency in 6.1.4.8.4.2.
In other words, the efficiency curve used for this subtype shall be the one embracing the smallest area.
System “families”
If the manufacturer produces the “same” system in different sizes, the different sizes of the system is considered being the same subtype (within the same system “family”). Detailed requirements for systems to be of the same subtype are given in Annex D.
Testing requirements for systems of the same subtype are:
- High temperature and safety tests (according to EN 12976) shall be performed on the sub system having the highest collector area to store volume ratio.
- All other tests (according to EN 12976 and including performance test) shall be performed on the “medium” sub system. Detailed testing requirements are given in Annex D.
Performance indicators for the system configurations which are not performance tested can be determined based on the performance test result on the “medium” system configuration according to the procedures described in Annex D.

Solar Certification Fund: 9th call
The Solar Certification Fund (SCF) launched its 9th call for proposals to continue to provide regular and reliable support for (1) developing better and new Solar Thermal certification and standardisation processes, (2) ensuring quality assurance for tomorrow's solar thermal technology.
This new call has an indicative budget of 120 000 Euros and the final allocation will depend on the relevance and quality of the proposals submitted.
The main priorities of this 9th SCF call are extensive and include:
• The development of specific tools, processes and methods to improve the existing Keymark Certificate,
• Work regarding the broadening of the scope of Solar Keymark Certification
• Promotion and quality assurance of solar thermal technology and the Solar Keymark Certification.The 9th SCF Call for proposals full text can be found here and the application form here.
The deadline for submitting proposals is Wednesday, 20th December 2017, 15h00 CET.
