IEA SHC Solar Academy on: Global Solar Certification Network (2)

SOLERGY – A new international label for high quality solar thermal products

Last year, the Global Solar Certification Network (GSCN) and the Solar Heating Initiative (SHI) joined forces for the common promotion of high-quality solar thermal products. In this context, the collector label SOLERGY will be jointly promoted worldwide. This webinar will provide information about the key elements of this alliance and its common project: the GSCN and the collector label SOLERGY. Furthermore, a collector manufacturer will report about his experience related to product certification on several continents based on the harmonized procedures established by the GSCN.

The webinar will welcome the following presenters:

- Dr. Harald Drück: GSCN - Unite for Solar Thermal
- Marisol Oropeza and Sören Scholz: Introduction to the collector label SOLERGY
- Harry Michalopoulos: Experience with GSCN and SOLERGY

The webinar will be moderated by Bärbel Epp from solrico.
