IEA SHC Solar Academy: Manufacturing and Design for Reliability and Durability in Solar Thermosyphon Hot Water Systems (1)
Join this session of the IEA SHC Solar Academy webinar series, where experts on solar hot water collector manufacturing, design, and operation will come together to discuss the reliability and durability issues that thermosyphon systems face when installed in the global south like southern Africa, China, and other regions (i.e., stagnation/over-temperature events, high irradiance levels, lack of supply water, corrosion, etc.). The work in this IEA network aims to identify the most suitable solar-derived hot water technologies for now and 2030, focusing on the development of solar thermal thermosyphon systems and solar photovoltaic self-consumption hot water systems, both of which are low-maintenance, cost-effective, and offer potential for further innovation. After hearing from our experts, this session will host a panel discussion on best practices and the potential ways forward by manufacturers, trainers, installers, and end-users in how everyone can work together to mitigate reliability and durability issues for solar hot water for 2030.
Speakers:
- Prof. Robert Taylor, UNSW, Australia - Presentation: Introduction & Overview
- Prof. Li Bojia, Solar Energy Application Center, China Academy of Building Research, China - Presentation: Initial results / findings on system ‘Reliability and Durability’
- Jiao Qingtai, Chief engineer of Solareast Group, China – Presentation: Current situation and development of solar hot water in China
- Rudi Moschik, AEE INTEC, Austria - Presentation: Current situation and development of solar hot water in Southern African Development Community (SADC) region
- Moderator: Bärbel Epp, Solrico
Q/A Session: This 90-minute webinar will include a 30-minute Q/A session and a recording of the webinar will be available online afterwards.
The webinar is organised by the Solar Academy of the IEA Solar Heating and Cooling Programme and hosted by ISES, the International Solar Energy Society.
Special announcement - Webinar re-run on 27 September 2024
ISES and the IEA SHC Solar Academy are happy to announce that this webinar will be broadcast again on 27 September 2024 at 6 AM GMT/UTC to accommodate our global audience, especially from Australia and Asia. The broadcast webinar will then be followed by a separate live Q/A with the webinar speakers starting at 7 AM GMT/UTC.

Prof. Robert Taylor
Prof. Robert A Taylor’s has served as an Academic at the University of New South Wales since 2011. His main research interest is in the development of ‘next generation’ solar and thermal energy systems. Drawing on the fields of heat transfer and nanotechnology, he is researching new/novel components, fluids, materials, and systems to increase the utilisation of solar energy in society. As such, his main goal is to provide a more efficient and more economic coupling between solar energy and useful thermal and/or electrical energy. In these areas, Prof. Taylor has published over 300 academic outputs which have been cited ~18,500 times according to Google Scholar: Robert A Taylor - Google Scholar
