6 Frequently Asked Questions about “Solar Collector Design Standards”
Do solar collectors need to be tested?
As the use of solar heating increases, so has the need for testing methods to evaluate the thermal and mechanical performance of solar collectors. Standards have been created over the years defining test methods and acceptable performance.
How to determine the thermal performance of solar collectors?
structure in a way that is deemed to result in decrease of thermal performance. Two generically different methods/ approaches are available in the standard to determine the thermal performance of solar collectors: The Steady state method and the Quasi dynamic method, hereafter generally abbreviated SS and QDT.
How are solar thermal collectors selected?
The solar thermal collectors being submitted for tests must be selected randomly by the designated representative of test laboratory or certification body (this is compulsory for certification according to the Solar Keymark Scheme rules but not a mandatory part of the standard).
What is the standard uncertainty in solar collector efficiency values?
For further information, see section 7.7. The overall standard uncertainty in solar collector efficiency values determined by an accredited test laboratory is about 3 %. The uncertainty in calculated energy gain is even higher and could exceed 10 % depending on the operating temperature and test method applied.
Does a solar collector need a freeze resistance test?
However in this case thermal performance, freeze resistance and internal pressure test of the collector is excluded. v. EN ISO 9488, Solar energy – Vocabulary (ISO 9488:1999). Many essential definitions are explained in this document e.g. collector area definitions.
How much solar irradiance is required for a flat plate collector?
For typical flat plate collectors, this condition usually will be satisfied if at least 80 % of the simulated solar radiation received at any point on the collector under test shall have emanated from a region of the solar irradiance simulator contained within a subtended angle of 60° or less when viewed from any point
