The Centre for Renewable and Sustainable Energy Studies hosted its annual national symposium to provide masters and doctoral students across South African institutions with the opportunity to present their research.
The 5th symposium took place from 13 to 14 July 2015 in the Knowledge Centre building of the Faculty of Engineering. This symposium incorporated the Solar Thermal Energy Research Group (STERG) symposium on the 14th July, which focused on solar thermal energy topics. The wind, ocean, bio-energy and solar photovoltaic (PV) technology platforms were the focus of the second day of the symposium.
The 2014 papers presented by the students in the renewable energy stream are listed below.
