Performance Evaluation of Magnifying Glass and Reflector Based Solar Cooker

Both parabolic and box type solar cookers have the potential to be effective and efficient solutions for various challenges related to health, economy, environment, and energy. The research conducted a comprehensive study to develop low-cost and efficient designs for these solar cooker models. To assess their performance, the research measured stagnation temperatures within the cooking chambers, conducted cooking trials, and evaluated the overall performance of different solar cooker types, including one parabolic, three box-type, and one panel cooker. The study also examined the thermal efficiency of these cookers and carried out water boiling and kitchen performance tests. These tests were conducted both with and without the use of heat-retaining materials to better understand the impact of thermal insulation.
