Performance Evaluation of an Enhanced Solar Still Using Simulink

Abstract

This study focuses on enhancing the efficiency of solar desalination, particularly for small communities facing water scarcity. Despite the economic viability of solar desalination, the method encounters a technical challenge related to low solar yield. The research proposes innovative solutions, notably the integration of a Compound Parabolic Collector (CPC) and Thermal Energy Storage (TES). The CPC system addresses low solar yield by minimizing losses through reflection, significantly improving the capture efficiency of solar radiation. Additionally, TES serves as a strategic storage component, storing solar energy and providing high energy when needed, thereby enhancing water evaporation rates. Using the SIMULINK platform for evaluation, the study demonstrates that the solar still, enhanced with TES and CPC, consistently produces an average of 15 liters of clean water. This positive outcome underscores the effectiveness of the proposed enhancements and suggests avenues for further refinement. The research not only addresses technical challenges but also establishes a foundation for ongoing improvements in solar desalination technology, offering potential solutions for water-scarce communities.
