Purpose: This study aims to develop a cost-effective and environmentally sustainable solar cooking solution for urban and rural populations in developing nations, where the majority rely on non-commercial sources of cooking energy.
Design/Methodology/Approach: The research involves designing a solar stove incorporating a thermal battery, heat-storing materials, and a photovoltaic system. Experimental trials were conducted to determine the melting points and density of different heat-storing materials: potassium nitrate, sodium nitrate, and their combination.
Findings: The experimental results indicate that a potassium and sodium nitrate mixture provides superior heat storage and release performance compared to the individual components. This combination shows promise for maintaining the necessary temperatures for cooking even in the absence of direct sunlight.
Research Limitation: The study is limited to specific heat-storing materials and laboratory-scale experiments, which may differ from real-world conditions.
Practical Implication: It could be especially beneficial for off-grid and rural areas in developing countries where traditional fuel sources are scarce or costly.
Social Implication: This research offers a renewable energy-based cooking method, improving energy accessibility, health, and quality of life for low-income populations.
Originality/Value: It utilises a combination of heat-storing materials that enhances the efficiency and reliability of cooking during off-sunshine hours, distinguishing it from other solar cooking technologies.
