Thermal energy storage (TES) systems are crucial for bridging the energy supply-demand gap. While solar energy storage research has focused on flat-plate collectors, the potential of Scheffler solar concentrators remains largely unexplored. This study proposes an innovative approach using a Scheffler solar concentrator and phase change material (PCM) to address energy needs in rural areas with limited electricity access. Real-time testing with paraffin wax as the PCM and computational fluid dynamics (CFD) analysis were performed. The CFD analysis indicated a charging time of 17 minutes, and experimental results showed 18 minutes. This approach demonstrates feasibility in meeting the energy demands of rural communities. Using the response surface method, the optimal charging time was approximately 20.5 minutes, with an optimal discharging time of around 26.3 minutes. Paraffin wax was selected as the PCM due to its desirable thermal properties, such as high latent heat and low cost. The study clarifies that the proposed approach aims to address various energy needs in rural areas, including household heating, cooking, and water sterilization. The study highlights the potential of Scheffler solar concentrators and PCMs for sustainable and reliable TES, offering clean and accessible energy solutions to rural areas with limited electricity access
