摘要

Solar cookers represent a transformative solution for rural communities facing energy poverty and environmental challenges. Solar energy plays an important role in the society as well as the community. This study evaluates the energy and exergetic evaluation impacts of solar cooker adoption in off-grid areas, focusing on their potential to alleviate their critical burdens. Through experimental testing and computational modeling, we quantify efficiency losses and identify key optimization parameters for each design. This research aims to make solar cookers more affordable and accessible for widespread rural community use. The research used the quasi-experimental method, comparing an experimental solar cooker and a control solar cooker. The experimental solar cooker is of the compound parabolic type generated by an inscribed parabolic curve. The compound conical reflector of the experimental solar cooker has been defined by comparison with a parabolic reflector and another conical reflector by simulation with SolTrace 3.4.0. The comparison of the energy and exergetic efficiency of the experimental and control kitchen has been carried out in climatic conditions of the Pune city, which is located in western region of India. The resulting energy efficiency of the experimental and control kitchens is 21.43% and 17.46%, respectively, and the exergetic efficiency of the experimental and control kitchens is 2.14% and 1.42%, respectively. The maximum exergetic power obtained with the experimental kitchen is 9.82 W for a temperature difference of 33.5 °C, and the maximum exergetic power obtained with the control kitchen is 5.8 W for a temperature difference of 27.1 °C. These findings position solar cookers as multi-benefit systems that simultaneously address energy access and climate change mitigation in large rural community contexts.
