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
Prof. Robert Taylor 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 utilization of solar energy in society. As such, his main goal is to provide a more efficient and 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
