IEA-SHC 43: On the Way to Harmonize Testing and Certification

When it comes to testing and certification, being a solar thermal manufacturer is definitely not easy: Both procedures have to be repeated in each region or country, in which you want to enter the market outside Europe. This not only slows down market introduction, but also increases the costs for any producer.

The newly formed task force 43 will discuss how to resolve discrepancies between and issues surrounding the different testing standards and their implementation. “This will create a technical foundation for certification bodies to consider accepting tests and certifications across borders, in order to lower barriers for solar heating and cooling products competing in global markets”, the task force writes on its website.

For example, whereas the SRCC standard requires using only one collector for sequential testing, test institutes in Europe allow the use of two identical collectors for parallel testing of 30-day stagnation and solar thermal efficiency. Listing other discrepancies between European and US testing procedures, SRCC’s director Les Nelson says: “The other significant differences are that European tests require a 4-hour rain spray test that is not used in the US, and the US test requires a ‘cold fill’ of a collector with water under stagnating conditions that is not required in European tests.”

The objective of the new IEA-SHC subtask A, “Collectors”, is to examine existing testing and certification procedures for low-temperature evacuated tube and flat-plate collectors, air heating collectors and medium- to high-temperature concentrating collectors. In contrast to that, Subtask B “Systems” will examine existing testing procedures for entire systems. The task force will have had its last meeting by June 2012.
