They treat the solar collector as a homogeneous body and they are based on four parameters that are considered characteristic: thermal capacity, heat removal coefficient, thermal efficiency coefficient and heat loss coefficient.
TestLab Solar Thermal Systems is accredited by the German Association for Accreditation (DAkkS) according to DIN EN ISO/IEC 17025:2018. TestLab Solar Thermal Systems is a testing laboratory recognized by DIN CERTCO. At our TestLab Solar Thermal Systems, we test solar collectors, components and complete systems.
All current testing standards are fulfilled and the outdoor test facilities are fully accredited within the TestLab Solar Thermal Systems for measurements according to EN 12975 / ISO 9806. To perform hail impact resistance tests at solar collectors as well as roof or facade components.
As already mentioned, the solar collector is a non-fixed object, whose characteristic parameters depend on the operating conditions.
The proper determination of the static and dynamic properties of a solar collector is of key significance, as they constitute a basis for the design of a solar heating installation, as well as a control system.
Furthermore the test facility is ready to classify the energy label for solar thermal products (energy label according to EU regulation No. 812/2013). The test facility is fully accredited within the TestLab Solar Thermal Systems for measurements according to EN 12976 und EN 12977 as well as other standards and regulations.
