Performance Assessment of a Solar Cooker Box Using Sand as a Heat Storage Material

This research explores the thermal performance of sand as a heat storage material in solar cookers, aiming to optimize their efficiency and reliability. Experimental analysis reveals sand's ability to absorb solar energy, reaching peak temperatures of 80°C, and gradually release stored heat over extended periods, enabling sustained cooking even in the absence of sunlight. Comparative results highlight sand's superiority over systems without heat storage, demonstrating its effectiveness in enhancing thermal stability and energy conservation. With its low cost, abundant availability, and ease of use, sand emerges as a viable material for sustainable solar cooking applications. Future studies are recommended to further optimize sand mixtures and integrate advanced designs for broader scalability.
