Large percentages of the South African population have no access to grid power and are located
at distances that make provision for such facility uneconomical. Also traditional fuels are under
pressure. Most areas in South Africa receive 300 days of sunshine per year. The proposed solar
system addresses the needs of such communities.
A solar thermal energy storage system utilizing phase change material has been proposed that can
overcome the time mismatch between solar availability and demand. The system consists of two
types of thermal heat storage. The latent heat storage used Phase Change Materials (PCM) which
melts at a sufficiently high temperature for cooking a variety of food types. By choosing a
suitable PCM to take advantage of the latent heat absorbed during phase changes. Heat losses
from both the latent heat storage and condenser are captured in the surrounding sensible heat
store.
The objective of this project to develop a prototype modules which together as a system could
provide the essential domestic power requirements of the target groups. This includes power for
cooking, hot water and in addition a limited electrical power supply for the system itself as well
as for other minor loads. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, Durban, 2008.
