IEA SHC Solar Academy: Global Solar Certification Network and SOLERGY (2)

About this webinar:

The Global Solar Certification Network (GSCN) is working on the global harmonization of procedures for testing, inspection and certification of solar thermal products in order to strengthen the market for quality solar thermal products. The GSCN established an alliance with the Solar Heating Initiative (SHI) to promote the global implementation of the collector label SOLERGY which is based on collector certification schemes acknowledged by the GSCN such as SolarKEYMARK and SRCC.

This webinar will provide information about the latest developments related to the GSCN and SOLERGY. Furthermore, information about the current status of the standards providing the basis for the certification of solar collectors will be presented. Also, a certifier and a solar collector manufacturer will share their experience as members of the GSCN.


The webinar will welcome the following presenters:

Dr. Harald Drück (University of Stuttgart) & Marisol Oropeza (Solar Heating Initiative) - Latest Developments Related to the Global Solar Certification Network (GSCN) and SOLERGY

Dr. Stephan Fischer (University of Stuttgart)Standards for Global Solar Collector Certification - Current Tests and Upcoming Changes

Shawn Martin (Solar Rating and Certification Corporation) - Certifiers’ Experience with GSCN

Harald Poscharnig (GREENoneTEC) - Manufacturers’ Experience with GSCN 

The webinar will be moderated by Bärbel Epp from solrico.
