The 6th Annual STERG Symposium took place on the 18th of July 2019 and the 19th of July 2019. We would like to thank all our sponsors, speakers and attendees! Some 23 research presentations were featured at the symposium this year, delivered by delegates from Stellenbosch University (SU), the University of Pretoria (UP), the University of the Free State (UFS) and the Vaal University of Technology (VUT). The event was co-hosted with the 10th Renewable Energy Postgraduate Symposium (REPS), organised by the Centre for Renewable and Sustainable Energy Studies (CRSES). REPS covers a broad range of energy technology, policy and economics research topics.

Three keynote addresses were provided by SolarPACES (delivered by Dr Matti Lubkoll on behalf of Mr Somila Xosa, South Africa’s ExCo representative) and Dr Willem Le Roux (UP) and Prof Johan van der Spuy (SU) speaking about respective university based technology research projects in the CSP sector. The presentations provided an excellent overview of local and global developments and dynamics in the CSP markets and of CSP technologies.
A diverse programme of industry presentations provided a timely update on challenges and successes in constructing and operating CSP plants, as well as industrial applications for high temperature solar heat and lessons arising from the PV industry. The ensuing panel discussion led by Prof Sampson Mamphweli saw industry participants engage with students and academics and offer their perspectives on developments in the global CSP markets.
