Solar cooker based on parabolic dish collector with phase change thermal storage unit was investigated. In this experimental setup, solar cooker with phase change thermal storage unit was kept on absorber plate of parabolic dish collector. During day time, acetanilide (phase change material) stores solar heat and during evening, solar cooker is kept in the insulator box. Then, the phase change material delivers heat to the food. To enhance the performance of solar cooker, three cases have been considered: ordinary solar cooker, solar cooker with outer surface painted black, and solar cooker with outer surface painted black along with glazing. It was observed that solar cooker with outer surface painted black along with glazing performs better as compared to other cases. Also phase change material (PCM) in solar cooker with outer surface painted black stored 26.8% more heat as compared to PCM in ordinary solar cooker, whereas PCM in solar cooker with outer surface painted black along with glazing stored 32.3% more heat as compared to PCM in ordinary solar cooker.
