Solar Academy Webinar

The Global Solar Certification Network (GSCN) is working on the global harmonization of procedures for testing, inspection and certification of solar thermal products 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.

During the webinar, you will learn about the latest GSCN and SOLERGY work plus information on standards used within the Global Solar Certification scheme. The webinar will conclude with first-hand experiences with the GSCN from a certifier and a manufacturer.

The webinar was moderated by Bärbel Epp from solrico.
