Abstract

Access to affordable and reliable electricity remains a significant challenge in Africa, particularly in remote and rural areas where centralised grid expansion is economically unfeasible. Small-scale solar organic Rankine cycle (SORC) systems offer a promising solution for decentralised power generation. The review explores the potential of solar organic Rankine cycle systems as a small-scale power generation solution for Africa with a specific focus on affordable components, including solar collectors, expanders and working fluids. It highlights the importance of cost-effective solutions for SORC. Despite considerable research on SORC systems globally, there is a noticeable lack of studies specifically addressing SORC performance in the climate conditions of Africa. Future research should prioritise optimising system design for this region, focusing on low-cost, robust solutions for variable solar input and limited infrastructure.
