The UP Solar Thermal Spoke has three primary objectives: capacity building, technology development, and decision support. Capacity building focuses on training postgraduate students at MEng and PhD levels, strengthening the pipeline of solar thermal expertise in South Africa. In terms of technology, the spoke aims to develop and improve solar thermal systems at both the component and plant levels, covering hardware and software solutions. This includes creating advanced methodologies, tools, and models for solar thermal analysis, design, and performance optimisation. Finally, in order to promote the sustainable adoption and expansion of solar thermal energy in South Africa, the spoke creates awareness and provides support that may enable stakeholders to make informed strategic decisions.
